A complex mathematical problem known as the Travelling Salesman Problem, and which is known to take a supercomputer days to solve, is effectively being solved by bees in real time. Researchers at Queen Mary, University of London and Royal Holloway have discovered that bees can quickly determine the shortest route between flowers even when they learn about the flowers in a different order. The problem that the Travelling Salesman must solve is finding the shortest route that allows him to visit all the locations on his route. The current method used by computers to solve it is by comparing the length of all possible routes and choosing the shortest. Scientists hope to study the bees to better manage our own networks while also learning the “minimal neural circuitry required for complex problem solving.”

According to our most recent studies, fears that we are the last generation to see coral reef due to the rising acidification of our waters is unfounded. This has been a fear raised by climate change studies which suggest CO2 concentration could jack up the pH balance of the seas and kill off marine life.

There is a whole ton of science on Matt Ridley’s awesome blog but here is the money shot:

In conclusion, claims of impending marine species extinctions driven by increases in the atmosphere’s CO2 concentration do not appear to be founded in empirical reality, based on the experimental findings we have analyzed above.

We are safe! Hooray!

No word on if we can just affect the pH balance enough to create monster fish or open a crack in an Arizona lake releasing thousands of blood-thirsty piranhas, in 3D.

Is our reality really 2D? Is our concept of third dimensional space really an optical illusion? Are our eyes deceiving us to believe we are anything other than Super Mario sidescrolling through life?

Is the above commercial featuring Peyton Manning and Justin Timberlake really a frightening prophecy?

Fermilab is currently building a Holometer to determine the answer to all these questions. Or something. To be honest, I really can’t even wrap my head around what they are talking about but here is open season for you kind readers to take your stab at it.

Israeli researchers have discovered a way to assemble transparent nanospheres that unite to form the stiffest biological material the world has ever seen. This could lead to printable body armor, tougher steel and more bullet-proof bulletproof glass.

There has been a long simmering debate in the scientific community over “the Hobbit” or Homo floresiensis by it’s fancy name. On one side is a cadre of folks who claim that the Hobbits (whose remains were first found inside a Indonesian cave in 2003) are a different species than humans.

But new research suggests those people can stick that theory in their pipes an smoke it. It looks like Homo floresiensis could be just regular old Homo sapiens afflicted with an iodine deficiency.

Oh well.

A new species of buffed-cheeked gibbon with a very distinctive call was identified by German researchers. Not only does this have implications on the heavily endangered gibbon in general, but the ape song could be the precursor to human music…

“An analysis of the frequency and tempo of their calls, along with genetic research, show that this is, in fact, a new species.”

The distinctive song “serves to defend territory or might even be a precursor of the music humans make,” the statement added.

Buffed-cheeked gibbon sounds like a third guy in on a remix, like “Tik Tok by Ke$ha feat. Lok D and Buffed-Cheek Gibbon.”

Okay, there is still no evidence that it actually happened but now science can explain a scenario in which the biblical parting of the Red Sea could have gone down. You know, without the power of a all-knowing God and stuff:

A strong east wind, blowing overnight, could have swept water off a bend where an ancient river is believed to have merged with a coastal lagoon along the Mediterranean Sea, said study team member Carl Drews of the National Center for Atmospheric Research. While archaeologists and Egyptologists have found little evidence that any events described in Exodus actually happened, the study outlines a perfect storm that could have led to the 3,000-year-old escape.

“People have always been fascinated by this Exodus story, wondering if it comes from historical facts,” Drews said. “What this study shows is that the description of the waters parting indeed has a basis in physical laws.”

Hell yeah.

Spider silk milked from goats may be used to replace body’s strained tendons, ligaments and bones in the future.

In a new experiment, Professor Lewis and his team at the University of Wyoming successfully implanted the silk-making genes from a golden orb spider into a herd of goats.

Spider silk has been used for centuries to dress wounds with varying degrees of success, but the problem has until now been how to get it.

“We needed a way to produce large quantities of the spider silk proteins,” News.com.au quoted Lewis, as saying.

He added: “Spiders can’t be farmed, so that route is out and since they make six different silks, even that would not work if you could.”

It’s all fun and games until spider DNA in a goat creates a real Chupacabra…

If you thought staying away from airports would keep you safe from the new full-body scanners that were recently deployed think again. As this video shows back-scatter enabled vans are already rolling out.

According to Forbes:

American Science & Engineering, a company based in Billerica, Massachusetts, has sold U.S. and foreign government agencies more than 500 backscatter x-ray scanners mounted in vans that can be driven past neighboring vehicles to see their contents

Due to this recent development, now may be the perfect time to invest in lead underwear.

Who hasn’t dealt with a psychopath? You offer to help them put a sofa in the back of a van one moment, badda bing badda boom you’re putting the lotion on your skin or else you get the hose again…

A new report by Scientific American’s MIND magazine looks into the new research being done into the area of criminally crazy people. Included among the findings on the studies of sociopaths:

• Aided by EEGs and brain scans, scientists have discovered that psychopaths possess significant impairments that affect their ability to feel emotions, read other people’s cues and learn from their mistakes.

• These deficiencies may be apparent in children who are as young as five years old.

• When you tally trials, prison stays and inflicted damage, psychopaths cost us $250 billion to $400 billion a year.

• Psychopaths have traditionally been considered untreatable, but novel forms of therapy show promise.

A cure for psychopaths! Rejoice, Great Big Fat People the world over!

Finally, science is addressing the truly important questions… Namely, why that homely girl you took home after a night of drinking seemed much hotter the night before.

…two photos of the same person were supplied. One was natural. The other was subtly altered to make their face less symmetrical. Symmetry is one of the keys to perceived beauty. Respondents were asked which photo they preferred.

In the second test, more altered photos were supplied. The pub-goers were asked to rate the attractiveness of those.

As it turns out, alcohol keeps us from properly assessing the symmetry in people’s faces, and as we all know the more symmetrical a face the more attractive we perceive it to be.  What’s worse is that the uglier the person is the more this effect is enhanced.

See? Now instead of making excuses to your friends you can defend yourself with sound scientific fact!

We told you last week about a possible new therapy hoping to regrow body parts. Unlike the ill-fated research of Dr. Curt Connors, it does not use the DNA of an animal that naturally regrows limbs so the likelihood of the recipient turning into a giant lizard and forcing Spider-man to do a backflip whilst saying something glib… is unlikely.

But that was that therapy. This therapy makes none of the same boring promises.

Scientists are regrowing mouse limbs with newt and salamander DNA and humans could be next.

“Newts regenerate tissues very effectively,” said Helen Blau, PhD, the Donald E. and Delia B. Baxter Professor and a member of Stanford’s Institute for Stem Cell Biology and Regenerative Medicine. “In contrast, mammals are pathetic. We can regenerate our livers, and that’s about it. Until now it’s been a mystery as to how they do it.”

Not noted in the story is that lightning struck right after she called mammals pathetic.

The unsolved puzzle to limb regeneration is apparently the rampant cancer that unchecked cell replication can kick start. Mouse trials have utilized two tumor-suppressing proteins to keep that mess in check.

Peter Parker, it’s time you came face to face with… The Newt.

Paging Dr. Connors… Dr. Curt Connors…

Researchers at the Tufts Center for Regenerative & Developmental Biology at Tufts University are testing whether a replicated amniotic (womb fluid) environment can promote limb regeneration in adult mammals.

Trials in rats have now begun. No word yet if Empire State University has received their grant yet…

Ladies and gentlemen, I present to you the Cadillac of dead body retrieval technology…

The system involves a small aluminum pipette that can detect trace amounts of a chemical called ninhydrin-reactive nitrogen, which collects in air pockets around a grave site. It’s the only known example of testing the chemical in its vapor phase, NIST says. As an added bonus, the system works at ambient temperatures instead of freezing cold, which could make it easy to transport.

Chemists Thomas J. Bruno and Tara M. Lovestead tested it on dead rats, burying some in 3 inches of soil and laying others on top of the soil. For comparison, they also tested boxes with no dead rats in them. The NRN compound was still detectable after nearly five months, the researchers say. A paper on their findings was published in the journal Forensic Science International.

Cross that one off your Christmas wish list.
