Awesome Thermochromic Jeans Changes Colors with Heat

Here's another off the wall pants idea from Naked and Famous Denim, the craziest jeans company in the entire world: Thermo-chromic denim. Jeans that change color depending on the temperature. Meaning if you get hot in certain areas (yeah, that too), the pants get whiter. More »

Mediterranean diet helps cut risk of heart attack, stroke: Results of PREDIMED study presented

Feb. 25, 2013 ? Results of the PREDIMED study, aimed at assessing the efficacy of the Mediterranean diet in the primary prevention of cardiovascular diseases, have been published in The New England Journal of Medicine. They show that the Mediterranean diet supplemented with extra-virgin olive oil or tree nuts reduces by 30 percent the risk of suffering a cardiovascular death, a myocardial infarction or a stroke.

The study has been coordinated by the researcher Ramon Estruch, from the Faculty of Medicine of the UB and the Hospital Cl?nic -- affiliated centres with the health campus of the UB, HUBc -- and has had the collaboration of the professor Rosa M. Lamuela and her team from the Natural Antioxidant Research Group of the Faculty of Pharmacy -- located at the campus of international excellence BKC -- which determined the biomarkers of Mediterranean diet consumption.

The research is part of the project PREDIMED, a multicentre trial carried out between 2003 and 2011 to study the effects of the Mediterranean diet on the primary prevention of cardiovascular diseases. The study was funded by the Carlos III Health Institute by means of the cooperative research thematic network (RETIC RD06/0045) and the CIBER of Physiopathology of Obesity and Nutrition (CIBERobn).

A total of 7,447 people following major cardiovascular risk factors participated in the study. They were divided into three dietary intervention groups: a Mediterranean diet supplemented with extra-virgin olive oil, a Mediterranean diet supplemented with nuts (walnuts, almonds, hazelnuts), and a low-fat diet (animal and vegetable). A dietician visited the patients every three months and they attended dietary training group sessions, in which they received detailed information about the Mediterranean and the low-fat diet, and the food included in each one. Moreover, they were provided with shopping lists, menus and recipes adapted to each type of diet and each season of the year.

During the study, those participants who followed any of the two types of Mediterranean diet received freely extra-virgin olive oil (one litre per week), and nuts (30 grams per day; 15 grams of walnuts, 7.5 grams of almonds and 7.5 grams of hazelnuts).

After five years, it has been proved that participants who followed any of the two types of Mediterranean diet showed a substantial reduction in the risk of suffering a cardiovascular death, a myocardial infarction or a stroke.

According to the researchers, the results of PREDIMED study are relevant as they prove that a high-vegetable fat diet is healthier at a cardiovascular level than a low-fat diet. The authors state that the study has been controversial as it provides new data to reject the idea that it is necessary to reduce fats in order to improve cardiovascular health.

Hopefully, these results will provide new references to prevent cardiovascular diseases. In addition, the design and methodology used can be easily transferred to the biomedical sector.

The study had the collaboration of several researchers from the Hospital Cl?nic, the Hospital del Mar Medical Research Institute (IMIM), the faculties of Medicine of the universities Rovira i Virgili, Navarra, Valencia, Canary Islands and Malaga, as well as the University Hospital Son Espases of Palma, the Fats Institute in Seville, and the primary health care networks of Barcelona, Seville, Tarragona and Valencia.

Jamie Dupree's Washington Insider: The sequester would really cut the budget

I know it's hard for many people to believe, but instead of just trimming the rate of increase in the federal budget, the $85 billion in automatic budget cuts set to hit on March 1 would actually result in less spending by Uncle Sam.

Really.

Here's the basic figures:

The stop gap budget that the federal government is operating under right now (through March 27) allows for a discretionary budget of $1.047 trillion in Fiscal Year 2013. (Discretionary means everything outside of Medicare and Social Security.)

If the automatic cuts actually go into effect in March, budget number crunchers here in Washington say the baseline for the federal budget would go from $1.047 trillion to $974 billion, a drop of $73 billion.

That is what you call a budget cut, not just a reduction in the rate of increase in the federal budget. The cuts would not be spread out over ten years, they would have to take place by September 30, when the fiscal year ends.

For example, this is the current budget plan with built-in increases for the feds each fiscal year, as agreed to by the Congress and the President:

2012 - $1.043 trillion
2013 - $1.047 trillion
2014 - $1.066 trillion
2015 - $1.086 trillion
2016 - $1.107 trillion
2017 - $1.131 trillion
2018 - $1.156 trillion
2019 - $1.182 trillion
2020 - $1.208 trillion
2021 - $1.234 trillion

You can see how the current plan for the federal budget is that it keeps going up each year, until it reaches $1.234 trillion in 2021. These spending cap numbers were agreed to in the Budget Control Act of 2011, the debt limit deal that included the sequester.

But all of those numbers would have to be lowered if the full $85 billion sequester goes into effect, as the baseline drops to $974 billion.?

Many Republicans say that's a choice which will ensure actual budget cuts, not just "budget savings" or "budget reductions," two phrases that often don't translate into real cuts.

President Obama on Tuesday called the cuts "brutal," saying a "meat cleaver" across the board cut is unacceptable.

One should note that the sequester was evidently his idea, and he signed the bill into law which provided for these automatic cuts.

Speaker Boehner has described the cuts in a similar fashion, labeling it a "meat ax" approach, as Republicans argue in favor of more targeted cuts.

It should also be noted that Congressional leaders named Boehner, Pelosi, Reid and McConnell all voted for the sequester bill - and then it was signed into law by the President.

Now with just over a week until the March 1 deadline (which was already postponed once from January 1), no one seems to be close to a deal on how to restructure the cuts to the liking of both parties.

So, if the automatic across the board cuts do go into effect - and stay in effect - there will be real cuts, not cuts in the rate of increase for the federal budget.

Really.

Unless there's some kind of deal to change the makeup of the $85 billion sequester.

Really.

Acura comes roaring back with NSX supercar

These days, it?s common for automakers to display ?concept cars? on the auto show circuit that are thinly disguised versions of upcoming production models ? like the MDX Acura introduced at the Detroit Auto Show last month.

But the show car that drew the real crowds was a model that won?t hit the street for at least two years, the reincarnation of Acura?s once formidable NSX supercar.

The Japanese maker is desperately hoping that the re-born NSX will grab the high-line brand some much-needed attention and bring curious new shoppers into Acura showrooms even before it reaches production.

When it was launched more than a quarter-century ago, Acura transformed the way Americans thought about Japanese cars, proving that the Asians could challenge the well-established European and domestic luxury brands. But the initial success of the Honda Motor Co. subsidiary proved far too fleeting and in recent years, Acura has lagged in the back of the premium pack.

The Detroit Bureau: Despite Recent Price Spike, DoE Expects Gas to Level Off, Even Decline

?It was a brave experiment when it was first launched,? says automotive analyst George Peterson, of AutoPacific, Inc. And now, he adds, there are signs Acura ?has hit bottom and is on the upswing.?

That was clearly something the maker intended to prove when it invited automotive journalists to the race track in Sonoma, California, several weeks back, to check out the new Acura RLX and pit it against some of its most formidable competitors, including the Mercedes-Benz E-Class and BMW 5-Series.

?This is a big deal for us,? asserted Mike Accavitti, the marque?s head of marketing. ?It?s the best product we have ever built.?

What the Honda subsidiary has pronounced its new ?flagship? is the direct heir to the original Acura Legend, a stylish and technically sophisticated product that turned conventional wisdom on its head. Produced in both coupe and sedan body styles, the original Acura model quickly ran up the sales chart and, if anything, created a conundrum for Honda officials who feared the Legend nameplate was better known than that of Acura itself.

The Detroit Bureau: Ford Looking to Novel Way to Get Back into Compact Pickup Market

Their solution proved disastrous. They not only replaced the Legend but switched to a new, European-style alphanumeric nameplate strategy for its replacement ? and for the new models to follow. The problem is that the cache of the original products was lost and motorists became completely confused by the new names; was the new flagship the RL or TL was a frequently heard question.

?Internally, they believe that (name) change cost them $1.5 billion in lost sales,? says Peterson, who has worked with Acura strategists over the years to figure out how to regain lost momentum.

Compounding the situation, Acura faced a wave of new competitors, including the even more up-market Japanese upstarts Lexus and Infiniti, launched by Toyota and Nissan respectively, which looked at Acura as a ?case study,? says the analyst.

Acura seemed to be regaining its footing in the early days of the new Millennium with an assortment of products such as the downsized RDX crossover, sales climbing to a record 209,610 in 2005 and putting it within striking distance of the first-tier luxury brands.

The Detroit Bureau: VW to Build 261 mpg 2-seater

But then, industry observers suggest, the Honda subsidiary again shot itself in the foot with a series of new mistakes, such as the introduction of an oversized chrome grille shield that has been derisively dubbed the ?beak.?

The new RLX and upcoming MDX feature a significantly smaller version of that shiny proboscis, but Acura remains committed to the alphanumeric nameplate strategy despite senior officials admitting it still confuses many customers.

But they?re hoping that a broader product line that is receiving generally positive reviews will overcome such concerns. It should also help, said Accavitti, to have new products like the Acura RLX offered at prices ?$1000s less than comparably equipped competitors.?

In keeping with its roots, meanwhile, the new models will also put an emphasis on advanced technologies, from state-of-the-art infotainment systems to the electric Super-Handling All-Wheel-Drive Acura will launch in the coming year.

That technical mouthful, abbreviated as e-SH-AWD, is a hybrid drivetrain that can deliver excellent fuel economy in routine driving but transform a vehicle like the RLX into a serious performance machine when the driver stomps the throttle. The unusual layout, which uses a V-6 gas engine and three electric motors also can direct power to individual wheels to help improve handling in aggressive turns, a concept known as torque vectoring.

An even more aggressive version of the system will be the fast-beating heart of the NSX, which is expected to debut in late 2014 or early 2015, Acura officials hint.

The maker clearly needs the boost. Sales tumbled to just 105,723 in 2009, a notably sharper downturn that the overall U.S. automotive market. Last year, the maker posted a strong gain, but at 156,216 cars and crossovers it was still down nearly 25% from its all-time high.

The new year is off to a good start, January volume up about 13%, year-over-year, buoyed by other new models such as the entry-lux sedan the Acura ILX.

Acura still has some serious challenges to overcome, but the maker appears to be making inroads after what some have dubbed a lost decade. It helps to have new products at the top and bottom of the luxury range ? and a striking new NSX supercar in the offing that packs potential buyers in whenever it goes on display.

Urijah Faber and Court McGee take UFC 157 wins

ANAHEIM, Calif. -- Urijah Faber and Court McGee got back on the winning track at UFC 157 on Saturday.

Faber got a first-round submission win over Ivan Menjivar. Faber and Menjivar started the fight with a rolling takedown and Faber ended up on top. He worked the top position until Menjivar got back to his feet. Faber held on, and while attached to Menjivar's back, Faber swung around and sunk in a rear naked choke. Menjivar tapped at 4:34 in the first round. The Anaheim crowd erupted for "The California Kid."

It was an important win for Faber after he lost a title fight to Renan Barao in July. The win puts him at 27-6, with five of his losses coming in title fights.

[Also: Ronda Rousey survives UFC debut, wins via first-round arm bar]

In earlier action, Court McGee punched his way to a decision win over Josh Neer. McGee used an effective strategy early on of working Josh Neer's body. Throughout the first round, Neer was hobbled by McGee's body punches. But in the second, McGee worked more on headshots. Though it wasn't as effective, McGee outstruck Neer. In the final round, McGee worked the ground game and controlled Neer while still leading on strikes. All three judges saw it 30-27 for McGee.

It was McGee's first fight at welterweight.

?I felt great at 170 lbs. This was a great move for me. I felt stronger, faster and had a lot more gas. I was told by FightMetric that I broke the record for most significant strikes ever in a welterweight fight and feel great. I could have stopped it, maybe, early with body shots but I was glad I put on a good performance.?

After the win, McGee's record is 15-3. Though he won "The Ultimate Fighter," he also lost two fights in 2012.

WATCH: Gay Couple Turned Away By Wedding Venue 'Because Of God'

A Texas-based gay couple is crying foul after they say they were turned down by a reception venue who refused to host their forthcoming wedding.

As WFAA News 8 reports, Ben Allen and Justin Hudgins hoped to book a reception for 150 guests at the All Occasion Party Place near Fort Worth. But the couple says they were told by phone and email that the venue wouldn't host a same-sex wedding.

?It is because of God that I will not be a part in your reception, and I know he loves you, but not what you are doing,? All Occasion Party Place employee Robin Hearne is quoted by the news channel as having written to Hudgins in an e-mail. ?I simply said I can not rent to you which is also my right.?

The couple, who will tie the knot in Mexico on April 6, say they were "floored" by the encounter.

"It almost felt like a sucker-punch to the face," Allen told NBCNFW. "I thought, in today's day and age, for someone to deny you simply because you date someone of the same sex, it doesn't really make sense to me."

As NBCNFW points out, the All Occasion Party Place is located outside the Fort Worth city limits, and therefore doesn't fall under the city's anti-discrimination code. Still, the case has nonetheless sparked the ire of local lesbian, gay, bisexual and transgender (LGBT) rights advocates.

Notes Chuck Smith of Equality Texas, "Refusing to provide services or public accommodations to anyone solely because of their sexual orientation or gender identity is wrong."

Allen and Hudgins' case follows that of an Oregon-based lesbian couple, who were turned away by a local bakery after they sought a wedding cake.

"I apologized for wasting their time and said we don?t do same-sex marriages,? Sweet Cakes by Melissa owner Aaron Klein is quoted by KATU as saying. ?I honestly did not mean to hurt anybody, didn?t mean to make anybody upset, [it?s] just something I believe in very strongly.?

In October 2012, a New York-based lesbian couple were similarly turned away by a rural farm where they hoped to tie the knot.

Robert Gifford, who owns Liberty Ridge Farm with his wife Cynthia, confirmed the news, telling WNYT: "I think it's our right to choose who we market to, like any business...we are a family business, and we just feel we ought to stay down the family path."

Fruit flies force their young to drink alcohol for their own good

Feb. 22, 2013 ? The fruit fly study adds to the evidence "that using toxins in the environment to medicate offspring may be common across the animal kingdom," says biologist Todd Schlenke.

When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps.

The discovery by biologists at Emory University is being published in the journal Science on February 22.

"The adult flies actually anticipate an infection risk to their children, and then they medicate them by depositing them in alcohol," says Todd Schlenke, the evolutionary geneticist whose lab did the research. "We found that this medicating behavior was shared by diverse fly species, adding to the evidence that using toxins in the environment to medicate offspring may be common across the animal kingdom."

Adult fruit flies detect the wasps by sight, and appear to have much better vision than previously realized, he adds. "Our data indicate that the flies can visually distinguish the relatively small morphological differences between male and female wasps, and between different species of wasps."

The experiments were led by Balint Zacsoh, who recently graduated from Emory with a degree in biology and still works in the Schlenke lab. The team also included Emory graduate student Zachary Lynch and postdoc Nathan Mortimer.

The larvae of the common fruit fly, Drosophila melanogaster, eat the rot, or fungi and bacteria, that grows on overripe, fermenting fruit. They have evolved a certain amount of resistance to the toxic effects of the alcohol levels in their natural habitat, which can range up to 15 percent.

Tiny, endoparasitoid wasps are major killers of fruit flies. The wasps inject their eggs inside the fruit fly larvae, along with venom that aims to suppress their hosts' cellular immune response. If the flies fail to kill the wasp egg, a wasp larva hatches inside the fruit fly larva and begins to eat its host from the inside out.

Last year, the Schlenke lab published a study showing how fruit fly larvae infected with wasps prefer to eat food high in alcohol. This behavior greatly improves the survival rate of the fruit flies because they have evolved high tolerance of the toxic effects of the alcohol, but the wasps have not.

"The fruit fly larvae raise their blood alcohol levels, so that the wasps living in their blood will suffer," Schlenke says. "When you think of an immune system, you usually think of blood cells and immune proteins, but behavior can also be a big part of an organism's immune defense."

For the latest study, the researchers asked whether the fruit fly parents could sense when their children were at risk for infection, and whether they then sought out alcohol to prophylactically medicate them.

Adult female fruit flies were released in one mesh cage with parasitic wasps and another mesh cage with no wasps. Both cages had two petri dishes containing yeast, the nourishment for lab-raised fruit flies and their larvae. The yeast in one of the petri dishes was mixed with 6 percent alcohol, while the yeast in the other dish was alcohol free. After 24 hours, the petri dishes were removed and the researchers counted the eggs that the fruit flies had laid.

The results were dramatic. In the mesh cage with parasitic wasps, 90 percent of the eggs laid were in the dish containing alcohol. In the cage with no wasps, only 40 percent of the eggs were in the alcohol dish.

"The fruit flies clearly change their reproductive behavior when the wasps are present," Schlenke says. "The alcohol is slightly toxic to the fruit flies as well, but the wasps are a bigger danger than the alcohol."

The fly strains used in the experiments have been bred in the lab for decades. "The flies that we work with have not seen wasps in their lives before, and neither have their ancestors going back hundreds of generations," Schlenke says. "And yet, the flies still recognize these wasps as a danger when they are put in a cage with them."

Further experiments showed that the flies are extremely discerning about differences in the wasps. They preferred to lay their eggs in alcohol when female wasps were present, but not if only male wasps were in the cage.

Theorizing that the flies were reacting to pheromones, the researchers conducted experiments using two groups of mutated fruit flies. One group lacked the ability to smell, and another group lacked sight. The flies unable to smell, however, still preferred to lay their eggs in alcohol when female wasps were present. The blind flies did not make the distinction, choosing the non-alcohol food for their offspring, even in the presence of female wasps.

"This result was a surprise to me," Schlenke says. "I thought the flies were probably using olfaction to sense the female wasps. The small, compound eyes of flies are believed to be more geared to detecting motion than high-resolution images."

The only obvious visual differences between the female and male wasps, he adds, is that the males have longer antennae, slightly smaller bodies, and lack an ovipositor.

Further experimentation showed that the fruit flies can distinguish different species of wasps, and will only choose the alcohol food in response to wasp species that infect larvae, not fly pupae. "Fly larvae usually leave the food before they pupate," Schlenke explains, "so there is likely little benefit to laying eggs at alcoholic sites when pupal parasites are present."

The researchers also connected the exposure to female parasitic wasps to changes in a fruit fly neuropeptide.

Stress, and the resulting reduced level of neuropeptide F, or NPF, has previously been associated with alcohol-seeking behavior in fruit flies. Similarly, levels of a homologous neuropeptide in humans, NPY, is associated with alcoholism.

"We found that when a fruit fly is exposed to female parasitic wasps, this exposure reduces the level of NPF in the fly brain, causing the fly to seek out alcoholic sites for oviposition," Schlenke says. "Furthermore, the alcohol-seeking behavior appears to remain for the duration of the fly's life, even when the parasitic wasps are no longer present, an example of long-term memory."

Finally, Drosophila melanogaster is not unique in using this offspring medication behavior. "We tested a number of fly species," Schlenke says, "and found that each fly species that uses rotting fruit for food mounts this immune behavior against parasitic wasps. Medication may be far more common in nature than we previously thought."

Toxic Medicine: How Venom Can Heal

Of the deadly animals in the wild, no pit viper or scorpion quite matches the hidden danger of the 3-inch long Conus magus, or "magical cone," snail.

On the ocean floor the snail tends to look like a seafaring paperweight, at least until dinner swims by.

Then the formerly unassuming snail uses its snakelike tongue, topped with a tiny harpoon, to inject its prey with immobilizing venom, turning a passing fish into a one-bite meal.

The venom is made up of approximately 200 different kinds of toxins and can kill a grown man as easily as it kills a guppy. Any human unlucky enough to be injected by the venom will be effectively paralyzed by the toxin-filled substance, which can lead to organ failure when the diaphragm muscles are no longer able to contract and pull oxygen into the lungs.

Jon-Paul Bingham, an assistant professor in the department of molecular biosciences and biological engineering at the University of Hawaii, has made a career of studying various species of the cone snail and characterizes them as "pretty horrific, pretty nasty."

But the venom, Bingham said, causes one surprising reaction in its victims: They feel no pain.

This venom's ability to cut off pain receptors has led to a second life as a powerful pain reliever called Prialt. The drug is 1,000 times more potent than morphine and is nonaddictive.

Prialt is just one example of the many ways venom components can be used in therapeutically. Currently, six venom-derived medications have been approved by the U.S. Food and Drug Administration, but new technologies and research have shown how proteins and toxins within venom can provide key blueprints for treating a wider variety of ailments, including autoimmune disease, stroke and multiple sclerosis.

Venom-based cures have been around since at least the seventh century B.C., when snake venom was used to treat arthritis and gastrointestinal problems. Modern venom-derived medications started in the 1970s, when pit viper venom was used to create blood pressure medication, with subsequent medications focusing mostly on the cardiovascular system. Approved by the FDA in 2004, Prialt is one of six drugs derived from venom proteins that were currently approved for use in the United States. Zoltan Takacs, a pharmacologist and founder of the World Toxin Bank, has spent much of his adult life attempting to unlock the key behind venom's potency, sometimes getting bit or stung in the process. Over millions of years, animal venom has evolved to reach specific pathways quickly, often affecting the cardiovascular or nervous systems in an animal's prey. By harnessing these same proteins within the venom, scientists are working to target these pathways for therapeutic reasons.

"Think of it, the very survival of the viper in the Sahara is dependent on its toxins," said Takacs. "For sure nature made them darn good. Literally, evolution has done half of the work for drug development."

With the "magician's cone" snail, the toxins contained within the venom have the ability to target specific channels within the cell that deal with pain.

Bingham said some pain medications were akin to a "skeleton key, which opens multiple locks," meaning the medications address the ailment but also cause side effects. Prialt taps only specific channels, lessening the chances of side effects.

"As pharmaceutical chemists, we want to redesign a key and be able to pick a lock with extreme specificity," said Bingham. "These specific keys that allow us to hit specific locks. We can only learn from them."

R&R Golf Cars closes shop, employees and customers seek answers

RANCHO MIRAGE, Calif. -

Chris Sharp, of Indio, got the news on Wednesday that he along with more than 20 employees at the 3-year-old business R&R Golf Cars in Rancho Mirage were being laid off.

"The owner came up and said we're closing the doors. We went bankrupt. We're done," said Sharp.

Sharp tells us the business closed shop only a week after he was promoted from delivery to parts manager.

"There's a lot of pissed off customers and a lot of angry employees. They have no communication. Everyone's confused on about what's going on out here," said Sharp.

Many of them showed up on Thursday in search of answers from the owner Rory Royston, 23. They also involved the sheriff's department while they could only watch as inventory was loaded up and towed away to be locked down in storage.

"They had trucks lined up. You couldn't even drive in here last night. You couldn't drive in here this morning. They were loading up the golf carts," said Christian Reyes, an employee at neighboring business Patios Plus.

A sign posted on the door reads that the business is closing and "current customers will recieve a call next week."

"They were angry. They wanted to know where their stuff was. They have people's golf carts that they paid for. And they rightfully should get some answers and they don't have that," said Reyes.

We called Royston. He says he laid off nearly two dozen employees at his Rancho Mirage show room and Palm Desert service department, admitting that his business went under and he's filing for bankruptcy.

It was a shock to some, however others felt it coming.

"I've been calling it that they were going out of business just because you couldn't order parts for weeks," said Geoffrey Benedetto, a former employee.

"He tried to grow too fast. He's a young owner, he's really young. He's 23 years old and he owns a multi-million dollar company. I just think he wanted to grow faster than he was able to do and kind of lost track of things," said Sharp.

Royston tells us he's working to "restructure so everyone gets paid."

Meanwhile, customers and vendors say they want their carts and their money.

"I hope that Rory does the right things and all the customers out here are happy and get taken care of and they don't have to deal with losing 10s of thousands of dollars," said Sharp.

Employee Jarvin Aivaz says he will personally help Royston deliver the carts without pay to their rightful owners on Friday.

Royston tells us he did the best he could as a young business owner, but unfortunately failed and hopes to bounce back.

ZTE Open, the company's first Firefox OS phone, gets a spec sheet at MWC

ZTE Open, the company's first Firefox OS phone, gets a full spec sheet at MWC

Remember that ZTE teased the MWC debut of its upcoming Firefox OS phone? Well, according to this spec sheet spotted by a tipster at ZTE's MWC booth, said device will be appropriately named ZTE Open, and it'll come with a moderate set of components: a Cortex-A5-based Qualcomm MSM7225A (which is known to clock at either 600MHz or 800MHz), a 3.5-inch HVGA TFT display with capacitive touchscreen, 256MB DDR SDRAM, 512MB NAND storage and the usual set of radios like WiFi 802.11a/b/g/n, Bluetooth 2.1 (with EDR3), GPS and FM radio. Interestingly, there will be a 3.2-megapixel front-facing camera, but it appears that there'll be none on the back. The Open will be available in three SKUs with different UMTS bands: 850/1900, 850/2100 and 900/2100. As always, we'll be sharing the full announcement and hands-on once we see the phone at MWC, though we have a feeling that we've already played with it before.

Update: As some of you have pointed out, yes, the "FF" may actually mean "fixed focus" instead of "front-facing," and the former seems more likely.

[Thanks, anonymous]

Why some soldiers develop PTSD while others don't

Feb. 21, 2013 ? Pre-war vulnerability is just as important as combat-related trauma in predicting whether veterans' symptoms of post-traumatic stress disorder (PTSD) will be long-lasting, according to new research published in Clinical Psychological Science, a journal of the Association for Psychological Science.

Researcher Bruce Dohrenwend and colleagues at Columbia's Mailman School of Public Health and the New York State Psychiatric Institute found that traumatic experiences during combat predicted the onset of the full complement of symptoms, known as the PTSD "syndrome," in Vietnam veterans. But other factors -- such as pre-war psychological vulnerabilities -- were equally important for predicting whether the syndrome persisted.

The researchers re-examined data from a subsample of 260 male veterans from the National Vietnam Veterans Readjustment Study. All of the veterans in the subsample had received diagnostic examinations by experienced clinicians that included information about the onset of the disorder and whether it was still current 11 to 12 years after the war ended.

Dohrenwend and colleagues focused on the roles of three primary factors: severity of combat exposure (e.g., life-threatening experiences or traumatic events during combat), pre-war vulnerabilities (e.g., childhood physical abuse, family history of substance abuse), and involvement in harming civilians or prisoners.

The data indicated that stressful combat exposure was necessary for the onset of the PTSD syndrome, as 98% of the veterans who developed the PTSD syndrome had experienced one or more traumatic events.

But combat exposure alone was not sufficient to cause the PTSD syndrome.

Of the soldiers who experienced any potentially traumatic combat exposures, only 31.6% developed the PTSD syndrome. When the researchers limited their analysis to the soldiers who experienced the most severe traumatic exposures, there was still a substantial proportion -- about 30% -- that did not develop the syndrome. This suggests that there were other factors and vulnerabilities involved for the minority of exposed who did end up developing the PTSD syndrome.

Among these factors, childhood experiences of physical abuse or a pre-Vietnam psychiatric disorder other than PTSD were strong contributors to PTSD onset. Age also seemed to play an important role: Men who were younger than 25 when they entered the war were seven times more likely to develop PTSD compared to older men. The researchers also found that soldiers who inflicted harm on civilians or prisoners of war were much more likely to develop PTSD.

The combined data from all three primary factors -- combat exposure, prewar vulnerability, and involvement in harming civilians or prisoners -- revealed that PTSD syndrome onset reached an estimated 97% for veterans high on all three. While severity of combat exposure was the strongest predictor of whether the soldiers developed the syndrome, pre-war vulnerability was just as important in predicting the persistence of the syndrome over the long run.

The researchers conclude that these findings have important implications for policies aimed at preventing cases of war-related PTSD.

Given the seemingly potent interaction between combat exposure and pre-war vulnerability, these results emphasize the need to keep the more vulnerable soldiers out of the most severe combat situations.

Dohrenwend and colleagues also point out that the recent conflicts in Iraq and Afghanistan, like the Vietnam War, are "wars amongst the people," and they underline the need for research examining the circumstances in which harm to civilians and prisoners is likely to occur. Such research could provide important clues for preventing such devastating violations of the rules of war.

In addition to Dohrenwend, co-authors on this research include Thomas Yager and Ben Adams at the Mailman School of Public Health at Columbia University; and Melanie Wall of the Mailman School of Public Health and Department of Psychiatry at Columbia University, and the New York State Psychiatric Institute.

The research was supported by the National Institute of Mental Health (Grant R01-MH059309) and by grants from the Spunk Fund, Inc. and a Ruth L. Kirschstein National Research Service Award from the National Institute of Mental Health.

Samsung Galaxy S4 Will Not Come with Exynos CPU, Nor Super AMOLED Display, Release Date Yet Unconfirmed

While the Samsung Galaxy S4 release date is getting closer, more leaked details about the next-gen flagship smartphone of the South Korea-based company are starting to hit the web.

After Eldar Murtazin, the faimous Russian blogger,?said that the Samsung Galaxy S4 release date was set for March 14th?during an event held in New York, the guys at Sammmobile?come with fresh details about the technical specifications of the Android-powered smartphone. It was just yesterday when we?ve told you that Galaxy S4 might not come with the Exynos 5 Octa SoC, as Samsung?s proprietary chipset has overheating issues, and today one of the biggest source for Samsung leaks are confirming the info.

According to a Samsung ?insider? quoted by the?aforementioned?tech publication the Samsung Galaxy S4 will be based on a Snapdragon 600 processor, similar to the one fitted inside the recently announced HTC One. The same report claims that the processor underpinning the Samsung flagship says that the Snapdragon 600 processor is overclocked at 1.9 GHz, compared to HTC One?s 1.7 GHz clock rate. The source also informs that Samsung Galaxy S4 will come with 2 GB of RAM and that it will be available in three variants with 16, 32, or 64 GB of internal storage.

The latest smartphone launches have indicated that the 1080p 5-inch displays are becoming the 2013 standard for the high-end Android segment. Samsung Galaxy S4 will reportedly boast a 4.99-inch screen with full HD resolution, but what?s even more interesting is that the South Korea-based company will ditch the Super AMOLED panels.

Sammobile?s trusted source says that the flagship smartphone will come with a SoLux Display, but didn?t reveal more details about it. Is it based on LCD3 technology like HTC One?s display? We don?t know yet, but if it is to believe Murtazin?s report, we will find out in less than a month.

The dimensions of the Samsung Galaxy S4 also leaked?alongside?with other details and it seems that the terminal will be 140.1 mm tall, 71.8 mm wide and 7.7 mm thin, thinner than it?s biggest rival, Apple?s iPhone 5. As it was previously reported the Galaxy S4 will keep the same two-capacitive-one-physical button combo below the 4.99-inch display.

A low-quality photo of the Galaxy S4 also leaked revealing a smartphone that is not following the design language introduced last year by the SGS3, but a square-ish device reminiscent of the Galaxy S2. We?d recommend you to take the rumor with a grain of salt, as the South Korea-based company is usually using some rubber cases on their prototypes, in order to make sure that the real design of their smartphone isn?t revealed ahead of the official announcement.

The Samsung insider quoted by Sammobile claims that the Galaxy S4?s back is made of plastic, but the smartphone?s sides are made of aluminium.

We know almost everything about the Galaxy S4 so far, and it was yesterday when some photo samples posted on Google Plus confirmed that the SGS4 will come with a 13 megapixel camera. We?ve exclusively told you about the Photo Sphere-like Samsung Orb camera feature of the Galaxy S4 a couple of days ago, and hopefully the company?s software?engineers?will get ready just in time to fit it inside the next-gen flagship, so the camera aspects of the new-comer will sure be impressive.

Are you excited by the Snapdragon 600 -?SoLux display team, or would you rather the Galaxy S4 coming with an Exynos chipset and Super AMOLED display? Please let us know in the comments section below.

New way to probe Earth's deep interior proposed

Feb. 21, 2013 ? Researchers from Amherst College and The University of Texas at Austin have described a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth.

There's just one catch: The technique relies on a fifth force of nature (in addition to gravity, the weak and strong nuclear forces and electromagnetism) that has not yet been detected, but which some particle physicists think might exist. Physicists call this type of force a long-range spin-spin interaction. If it does exist, this exotic new force would connect matter at Earth's surface with matter hundreds or even thousands of kilometers below, deep in Earth's mantle. In other words, the building blocks of atoms -- electrons, protons, and neutrons -- separated over vast distances would "feel" each other's presence. The way these particles interact could provide new information about the composition and characteristics of the mantle, which is poorly understood because of its inaccessibility.

"The most rewarding and surprising thing about this project was realizing that particle physics could actually be used to study the deep Earth," says Jung-Fu "Afu" Lin, associate professor at The University of Texas at Austin's Jackson School of Geosciences and co-author of the study appearing this week in the journal Science.

This new force could help settle a scientific quandary. When earth scientists have tried to model how factors such as iron concentration and physical and chemical properties of matter vary with depth -- for example, using the way earthquake rumbles travel through Earth or through laboratory experiments designed to mimic the intense temperatures and pressures of the deep Earth -- they get different answers. The fifth force, assuming it exists, might help reconcile these conflicting lines of evidence.

Earth's mantle is a thick geological layer sandwiched between the thin outer crust and central core, made up mostly of iron-bearing minerals. The atoms in these minerals and the subatomic particles making up the atoms have a property called spin. Spin can be thought of as an arrow that points in a particular direction. It is thought that Earth's magnetic field causes some of the electrons in these mantle minerals to become slightly spin-polarized, meaning the directions in which they spin are no longer completely random, but have some preferred orientation. These electrons have been dubbed geoelectrons.

The goal with this project was to see whether the scientists could use the proposed long-range spin-spin interaction to detect the presence of these distant geoelectrons.

The researchers, led by Larry Hunter, professor of physics at Amherst College, first created a computer model of Earth's interior to map the expected densities and spin directions of geoelectrons. The model was based in part on insights gained from Lin's laboratory experiments that measure electron spins in minerals at the high temperatures and pressures of Earth's interior. This map gave the researchers clues about the strength and orientations of interactions they might expect to detect in their specific laboratory location in Amherst, Mass.

Second, the researchers used a specially designed apparatus to search for interactions between geoelectrons deep in the mantle and subatomic particles at Earth's surface. The team's experiments essentially explored whether the spins of electrons, neutrons or protons in various laboratories might have a different energy, depending on the direction with respect to Earth that they were pointing.

"We know, for example, that a magnet has a lower energy when it is oriented parallel to the geomagnetic field and it lines up with this particular direction -- that is how a compass works," explains Hunter. "Our experiments removed this magnetic interaction and looked to see if there might be some other interaction with our experimental spins. One interpretation of this 'other' interaction is that it could be a long-range interaction between the spins in our apparatus and the electron spins within the Earth, that have been aligned by the geomagnetic field. This is the long-range spin-spin interaction we were looking for."

Although the apparatus was not able to detect any such interactions, the researchers could at least infer that such interactions, if they exist, must be incredibly weak -- no more than a millionth of the strength of the gravitational attraction between the particles. That's useful information as scientists now look for ways to build ever more sensitive instruments to search for the elusive fifth force.

"No one had previously thought about the possible interactions that might occur between the Earth's spin-polarized electrons and precision laboratory spin-measurements," says Hunter.

"If the long-range spin-spin interactions are discovered in future experiments, geoscientists can eventually use such information to reliably understand the geochemistry and geophysics of the planet's interior," says Lin.

Funding for this research was contributed by the National Science Foundation (grants PHY-0855465, PHY-1205824, EAR-1056670 and EAR-1053446), the Department of Energy's Center for Energy Frontier Research in Extreme Environments (EFree), and the Carnegie/DOE Alliance Center (CDAC).

Stricter gun laws alone won't stop America's urban violence

Getting guns off the streets or out of the hands of criminals won?t by itself address the problem of gun violence in poor urban communities. America needs to address the underlying circumstances that lead people like my inmate students to gun violence in the first place.

By Peggy Rambach / February 21, 2013

Darrell Hartley takes notes during a class run by The Insight Prison Project in a San Quentin, Calif., prison on Jan. 23, 2008. Op-ed contributor Peggy Rambach says implementing the social programs 'that will eradicate the causes for their fear' mean her inmate 'students won?t be condemned to find sanctuary behind prison walls simply because they were too young to know that they would never find it in a gun.'

Robert Gumpert/Special to the Christian Science Monitor

When my students told me that they hated guns, I was surprised. That?s because my students are criminals incarcerated at Suffolk County House of Correction, a medium security prison in Boston where I teach creative writing. I found out about this relationship with guns the day Mario (I use only his first name to protect his identity) read his poem ?The Hammer.? It described how a gun at first empowers a man, but then, like an addiction, the man is overpowered by the gun, and the gun leads him to his death. Apparently, the poem spoke for the whole class. They all said that they wished they?d never laid their hands on one.

But many of them will pick one up the minute they?re back on the street. Not because of the gun. Because of the street.

In the wake of Newtown, there?s been a huge push for gun control ? not just to protect children in suburban schools from mass shootings but to minimize the more frequent gun violence that dominates our urban streets. As I?ve learned from my students, getting guns off the streets or out of the hands of criminals won?t by itself address the problem of gun violence in poor urban communities. America needs to address the underlying circumstances that lead people such as my students to gun violence in the first place.

Especially if their lives resemble the life of my student Robert. He grew up in the 1980s at the height of the crack epidemic, turned up the volume on the TV to drown out his parents? fights over his father?s habit, and lived in an apartment where a bullet just missed him one day when it flew through his window.

When Robert was 10 years old and walking to school in a snowstorm, a guy shoved a gun in his face and, as Robert wrote, stole his coat, hat, and shoes. Whoever had guns had all the power, Robert said, ?and the GI Joe I played with, had a [big] gun, too.? Robert?s first offense was for illegal possession of a firearm, and so was his second.

My students carried guns, but they also know that guns bring nothing to their life that is good. The day Harvey tried writing a poem about how it felt to be shot, the class spoke over each other to help him get it right, and I found out that just about every other man in the room had been shot, too.

In my student Tali?s short story, a bodega owner didn?t send off his customers with a ?Have a good day,? but said, instead, ?Be careful out there.?

And Mike, running through nearby Charlestown, armed with a 2X4 to do battle against a gang he didn?t know and had nothing against, compared the sound of his and his friends? feet to the march of an infantry.

Caves point to thawing of Siberia

Friday, February 22, 2013

Evidence from Siberian caves suggests that a global temperature rise of 1.5 degrees Celsius could see permanently frozen ground thaw over a large area of Siberia, threatening release of carbon from soils, and damage to natural and human environments.

A thaw in Siberia's permafrost (ground frozen throughout the year) could release over 1000 giga-tonnes of the greenhouse gases carbon dioxide and methane into the atmosphere, potentially enhancing global warming.

The data comes from an international team led by Oxford University scientists studying stalactites and stalagmites from caves located along the 'permafrost frontier', where ground begins to be permanently frozen in a layer tens to hundreds of metres thick. Because stalactites and stalagmites only grow when liquid rainwater and snow melt drips into the caves, these formations record 500,000 years of changing permafrost conditions, including warmer periods similar to the climate of today.

Records from a particularly warm period (Marine Isotopic Stage 11) that occurred around 400,000 years ago suggest that global warming of 1.5?C compared to the present is enough to cause substantial thawing of permafrost far north from its present-day southern limit.

A report of the research is published in this week's Science Express. The team included scientists from Britain, Russia, Mongolia and Switzerland.

'The stalactites and stalagmites from these caves are a way of looking back in time to see how warm periods similar to our modern climate affect how far permafrost extends across Siberia,' said Dr Anton Vaks of Oxford University's Department of Earth Sciences, who led the work. 'As permafrost covers 24% of the land surface of the Northern hemisphere significant thawing could affect vast areas and release giga-tonnes of carbon.

'This has huge implications for ecosystems in the region, and for aspects of the human environment. For instance, natural gas facilities in the region, as well as power lines, roads, railways and buildings are all built on permafrost and are vulnerable to thawing. Such a thaw could damage this infrastructure with obvious economic implications.'

The team used radiometric dating techniques to date the growth of cave formations (stalactites and stalagmites). Data from the Ledyanaya Lenskaya Cave ? near the town of Lensk latitude 60?N ? in the coldest region showed that the only period when stalactite growth took place occurred about 400,000 years ago, during a period with a global temperature 1.5?C higher than today. Periods when the world was 0.5-1?C warmer than today did not see any stalactite growth in this northernmost cave, suggesting that around 1.5?C is the 'tipping point' at which the coldest permafrost regions begin to thaw.

Dr Vaks said: 'Although it wasn't the main focus of our research our work also suggests that in a world 1.5?C warmer than today, warm enough to melt the coldest permafrost, adjoining regions would see significant changes with Mongolia's Gobi Desert becoming much wetter than it is today and, potentially, this extremely arid area coming to resemble the present-day Asian steppes.'
