Hagfish-slime clothes could be new fashion statement



Hagfish? More like "hagfashion!"

Welcome to the library. Would you rather read the book "50 Shades of Grey" or the article "The production of fibers and films from solubilized hagfish slime thread proteins?" Good choice! Here's your hagfish reading.


For defensive purposes, hagfish produce a slime full of protein threads. Draw it out into a thread, and you have the potential for an incredibly strong fabric that isn't made from petroleum like popular existing synthetics.


A team from the University of Guelph in Ontario, Canada, is looking to turn this hagfish squickiness into the latest fabric. The newest breakthrough is the ability to extract a cord of material from processed hagfish slime. This is the sort of awesome thing scientists (and we at Crave) get excited about.



My dream of vast hagfish ranches isn't likely to come true. The ultimate goal is to re-create the hagfish goodies using biomimetic methods such as modifying bacteria to create the protein threads.


I can't wait for the day when I'm all dressed up for a fancy event and someone comes up to me to say, "Oh, what a lovely dress!" I'll say, "Thank you, it's made from hagfish slime."


For a more visceral look at the stuff behind your future hagfish clothes, check out the video demonstrating a fiber pull from the gooky material. All that's missing is a pulsing techno soundtrack.

Plants Grow Fine Without Gravity


When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Royal Hoax: DJs 'Shattered' After Nurse's Suicide













The two Australian radio DJs who prank-called the London hospital where Kate Middleton was being treated last week said they were "shattered" and "gutted" after the nurse who answered their call apparently killed herself.


Shock jocks Mel Greig, 30, and Michael Christian, 25, cried as they spoke to Australia's Channel 9 overnight in their first public interview since Jacintha Saldanha, 46, the nurse who last week connected the pair to the duchess' room, was found dead Friday morning.


"I'm shattered, gutted, heartbroken," Christian said. "Mel and myself are incredibly sorry for the situation and what's happened. I had the idea. … It was just a simple harmless phone call. It was going to go on for 30 seconds. We were going to get hung up on."

The host of the "2Day" FM radio show pretended to be Queen Elizabeth and Prince Charles, asking for an update on Middleton's condition when they called up King Edward VII Hospital in central London. With no receptionist on duty overnight, Saldanha answered the prank call and put it through.


"It was just something that was fun and light-hearted and a tragic turn of events that I don't think anyone had expected," Christian said.

Saldanha was found dead Friday morning after police were called to an address near the hospital to "reports of a woman found unconscious," according to a statement from Scotland Yard.


Investigators have not said how she might have killed herself.


Greig cried today when asked about the moment she heard of the death of Saldanha, a mother of two.


"It was the worst phone call I've ever had in my life," she said through tears. "There's not a minute that goes by that we don't think about her family and the thought that we may have played a part in that is gut-wrenching."


The DJs said they never expected to get through to Middleton's nurse and assumed "the same phone calls had been made 100 times that morning," Christian said.


Grieg said, "We wanted to be hung up on with our silly voices and wanted a 20-second segment to air of us doing stupid voice. … Not for a second did we expect to even speak to Kate or even have a conversation with anyone at the hospital. We wanted to be hung up on."


The global backlash against the duo has been fierce, from online death threats to calls for prison time. Their radio station has announced it is banning phony phone calls altogether, and suspending advertising indefinitely.


Max Moore-Wilton, the chairman of Southern Cross Austereo, said in a letter Sunday to Lord Glenarthur, chairman of King Edward VII's Hospital, that the company is reviewing the station's broadcast policies, the AP reported.


"I can assure you we are taking immediate action and reviewing the broadcast and processes involved," Moore-Wilton said in the letter. "As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable."


Greig and Michael have been taken off the air, silenced indefinitely.

Female lemurs avoid the wrong love in the dark



































IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.












The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).












Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

Nobel-winners vow Europe will emerge stronger from crisis






OSLO: The three European Union leaders in Norway to collect the Nobel peace prize moved Sunday to defuse criticism of the 2012 award, vowing the crisis-hit bloc would emerge strong and remain on a course of peace.

"Europe is going through a difficult period," EU president Herman Van Rompuy told a packed news conference on the eve of the awards ceremony.

"We are working hard, jointly as a union and in all individual countries, to overcome these problems," he added.

"I'm sure we will succeed. We will come out of this time of uncertainty and recession stronger than we were before."

Van Rompuy was speaking in euro-sceptic Norway, a country stubbornly opposed to joining the bloc.

As protests and job cuts traumatise Europe after three years of dire economic crisis, the Nobel Committee has come under attack for its decision to commend the EU for turning a continent at war into a continent at peace.

But the Nobel Committee chairman, the ardently pro-European Thorbjoern Jagland, justified the choice by the absence of conflict on a scale seen in the two world wars of the 20th century.

"The disputes and dramas have never led to war. On the contrary they have led to compromises,"

But highlighting the strain building as the EU weathers its worst crisis in 60 years, half a dozen leaders, including Britain's premier David Cameron, will snub Monday's ceremony.

"We want Europe to become again a symbol of hope," Van Rompuy added.

He flew into snowbound Oslo with European Commission chief Jose Manuel Barroso and European parliament head Martin Schulz. Together, they will pick up the prize on behalf of the EU.

But the crisis is undermining solidarity and generosity inside the EU.

Only last month, efforts to agree a new multi-year budget collapsed month in an ugly showdown between the rich nations of northern Europe and the struggling economies of the south.

And as the jobless figures rise, so too does support for nationalist and xenophobic movements.

In Greece, where unemployment is running at one-in-four and in Spain, where a half of under-25s are jobless, there is increasing talk of a "lost generation".

"The unprecedented financial crisis shows we were not fully equipped to cope with a crisis of this magnitude," Barroso conceded.

But the answer, he said, was more union. "All the steps were in favour of more integration, not less."

And he still hoped for agreement at a summit next week, only four days after the Nobel award. That meeting will look at setting up a banking union between the 17 eurozone nations, a first step towards tighter economic and monetary union.

Attending the ceremony in Oslo will be the leaders of the "big two" powers, France and Germany, Francois Hollande and Angela Merkel.

But relations between these two are rocky, with disagreements between the two leaders holding up the deal on a banking union.

Hailing the bloc's contribution in strengthening democracy for half a billion people -- some only recently emerging from authoritarian regimes -- Barroso said that "over the next 60 years Europe must lead the global quest for peace."

And next year, the bloc prepares to enlarge yet further by embracing Croatia as its 28th member next year.

Shulz, a German Socialist at the head of the European parliament, said the award must be "a warning, an alert" to stick to the ideals of the founders of the bloc in the aftermath of World War II.

John McAfee feeling better, fights to stay in Guatemala

Antivirus-software pioneer John McAfee, who is facing deportation from Guatemala to Belize in connection with a murder, is feeling better after suffering chest pains earlier this week and has filed three appeals in an effort to stay in the country.


McAfee, whose request for political asylum has already been rejected by the Guatemalan government, filed an appeal of the asylum decision and petitions to stay in the country indefinitely, as well as another that ensures his physical integrity, his attorney told the media.


Attorney Telesforo Guerra told reporters outside the detention center where McAfee has been held since his arrest Wednesday that the software pioneer turned fugitive is in good health, according to the Associated Press. McAfee, who was arrested for entering the Central American country illegally, complained of chest pains not long after his request for political asylum was rejected by the Guatemalan government on Thursday. His attorney later said that his client was suffering from stress and hypertension.


Police in neighboring Belize has been pursuing McAfee for the past few weeks in connection with the shooting death of his neighbor. McAfee had been on the run since November 12, when his neighbor Gregory Faull, a contractor and restaurant owner, was discovered with a bullet in his head.




The 67-year-old founder of the company that bears his name has also said he would like to return to the United States.


"My goal is to get back to America as soon as possible," McAfee told Reuters. "I wish I could just pack my bags and go to Miami. I don't think I fully understood the political situation. I'm an embarrassment to the Guatemalan government and I'm jeopardizing their relationship with Belize."


McAfee has told the media that he's being wrongfully persecuted by officials in Belize and that he fears for his life if he is arrested by Belize police.

Cowboys Players Were Like 'Brothers'













Dallas Cowboys players Joshua Price-Brent and Jerry Brown Jr., had a brotherly bond that began when they were teammates at the University of Illinois and carried on when they were both signed, in different years, to the NFL franchise.


But in an instant, the lives of the young, successful men who were living out their NFL dreams were altered.


Irving police suspect Price-Brent, 24, was intoxicated when he was behind the wheel of his 2007 Mercedes early Saturday morning. He was allegedly speeding when his car hit a curb, flipped, landed in the middle of a service road and caught fire, killing his passenger, Brown, 25, who had been a linebacker on the Cowboys practice squad.


Price-Brent, who is scheduled to be arraigned today on an intoxication manslaughter charge, released a statement Saturday night from his jail cell.


"I will live with this horrific and tragic loss every day for the rest of my life," he wrote.


His attorney, George Milner, called Brown's death a "tremendous loss" and said "this was like losing a little brother" for his client.








Kansas City Chiefs Player Jovan Belcher's Murder-Suicide Watch Video





Authorities were alerted to the accident, which occurred at about 2:21 a.m., by several 911 callers, Irving Police Department spokesman John Argumaniz said. When police arrived, they found Price-Brent pulling Brown from his 2007 Mercedes, which had caught fire, he said.


Brown was unresponsive and was transported to a local hospital, where he was pronounced dead.


It was not known where the men were coming from or where they were going, but Argumaniz said officers suspected alcohol may have been a factor in the crash and asked Price-Brent to perform field sobriety tests.


"Based on the results of the tests, along with the officer's observations and conversations with Price-Brent, he was arrested for driving while intoxicated," Argumaniz said.


This is the second week in a row an NFL player has been accused of being involved in another person's death. Jovan Belcher of the Kansas City Chiefs killed his girlfriend early Dec. 1, then committed suicide while talking to team officials in the parking lot at Arrowhead Stadium.

Price-Brent was taken to a hospital for a mandatory blood draw where he was treated for minor scrapes, Argumaniz said. He was then booked on an intoxication manslaughter charge after it was learned Brown had died of injuries suffered in the crash.


It is expected that results from the blood draw could take several weeks, the police spokesman said.


If convicted, the second-degree felony intoxication manslaughter charge carries a sentence of two to 20 years in prison and a $10,000 fine.


Milner suggested that ongoing construction in the area of the crash may have played a role.

Kenyan elephant numbers plummet by 1000 in four years









































IT'S a case of up then down for Kenya's second largest population of elephants. After a promising growth spurt, the elephants are now dying faster than they are being born. The decline is being blamed on illegal poaching, driven by Asia's demand for ivory.












The Kenya Wildlife Service recently conducted a census of the Samburu/Laikipia population, the country's second largest. It found that the population lost over 1000 elephants in just four years, and now stands at 6361. Previous censuses in 1992, 1998, 2002 and 2008 had revealed a growing population, which appears to have peaked at 7415 in 2008.












Poaching is suspected. A July report by three conservation groups found that it has been on the rise across Africa since 2006. Poaching is also spreading eastwards from central Africa into countries like Kenya, says Richard Thomas of TRAFFIC in Cambridge, UK, one of the three groups that drafted the report. The July report found that more than half of all elephants found dead in Africa in 2011 had been illegally killed.












The rise in poaching appears to be driven by increasing affluence in China and Thailand, where ivory is often used to make religious sculptures and other decorations.












Organised criminal gangs have capitalised on this increased demand. "If it's worth someone's while to smuggle the ivory, they'll take the risk," Thomas says. There is evidence that gangs are moving into Kenya to hunt elephants.

Football: Comfortable Bayern cruise as Dortmund slip






BERLIN: Bayern Munich moved a step closer to the Bundesliga title on Saturday as they beat Augsburg 2-0 and extended their lead over two-time reigning champions Borussia Dortmund to 14 points.

Thomas Mueller and Mario Gomez scored in Bayern's victory while 10-man Dortmund lost 3-2 at home against Wolfsburg. Munich jumped onto 41 points while Dortmund remained on 27 points one game day before the winter break.

Second-placed Bayer Leverkusen have 30 points and will play at Hanover 96 on Sunday.

Bayern dominated the proceedings in Augsburg and finally grabbed the lead in the 40th minute from the spot through Mueller after Augsburg's Gibril Sankoh handled Toni Kroos' pass.

Mario Gomez doubled the advantage in the 62nd minute, just two minutes after coming on, to decide the contest.

"Three points, so it was a nice Saturday," said Bayern captain Philipp Lahm.

"In order to win the championship, we have to win these kinds of game, and we did that," said Gomez.

In Dortmund, Juergen Klopp's hosts went ahead on a free kick by Marco Reus in the sixth minute.

Wolfsburg equalised in the 36th minute from the spot through Diego one minute after Marcel Schmelzer was red-carded for stopping Bas Dost's shot on the line with his hand - though replays showed the defender blocked the ball with his knee.

Wolfsburg took a 2-1 lead in the 41st minute as Naldo volleyed home Diego's free kick pass.

Jakub Blaszczykowski converted a penalty in the 61st minute as Dortmund pulled even at 2-2 but Dost re-established Wolfsburg's lead in the 73rd minute.

"I am satisfied with our performance - but the result hurts us a lot," said Klopp.

"It decided the game that we had to play the final 54 minutes a man down. Still, we had more ball possession and still felt we could win. But it was difficult to maintain the high energy level."

Fourth-placed Schalke 04's dropped further behind the leading trio with a 3-1 loss at VfB Stuttgart thanks to Vedad Ibisevic's hat-trick.

Stuttgart, who pulled even with Schalke with 25 points each, stormed ahead after two minutes through Ibisevic before Schalke equalised in the 12th minute though Ciprian Marica.

Ibisevic gave Stuttgart the lead 2-1 from the spot in the 38th minute and completed his hat-trick after 61 minutes.

Both teams finished with 10 men as Gotoku Sakai of Stuttgart (67th minute) and Schalke's Jermaine Jones (73rd) were sent off.

With 24 points, Eintracht Frankfurt could pass Schalke if they get a point at home against Werder Bremen later Saturday.

On Friday, Artjoms Rednevs scored two goals in Hamburg's 2-0 victory at home over Hoffenheim. Hamburg have 24 points and Hoffenheim 12.

Sebastian Polter (27th minute) and Markus Feulner (90th) scored to give Nuremberg (19 points) a 2-0 win over Fortuna Duesseldorf (18).

Freiburg (23) won 1-0 over Greuther Fuerth (8) thanks to Daniel Caligiuri's goal in the 15th minute.

The other Sunday match is Borussia Moenchengladbach (21) hosting Mainz 05 (23).
