Researchers have developed a new method of repairing bone using a synthetic bone graft substitute material. Combined with gene therapy, they say it can mimic real bone tissue and has potential to regenerate bone in patients who have lost large areas of bone from disease or trauma.

The researchers have developed a scaffold material made from collagen and nano-sized particles of hydroxyapatite which acts as a frame for the body’s own cells and repairs bone in the damaged area using gene therapy. The cells are tricked into overproducing bone producing BMPs (proteins), encouraging regrowth of healthy bone tissue. 

Can anyone accurately forecast the result of the London Olympics while they are a week away?

Even more daring, can they forecast results without in depth knowledge of athlete training?

Economists at Ruhr-Universität Bochum are taking a shot at it and, if it sounds like complete madness, we'll go ahead and spoil it and tell you they believe that China, USA, and Russia will top the score table with 102, 100, and 71 medals, respectively, so you can move on to another article. 

But if you are interested in the nuts and bolts, read on.  You can decide if this is mumbo-jumbo or solid science.

Can modern physicists examine ancient myths and teach us about modern social networks, even science ones like Science 2.0?

Pesky humanities types are always butting into science and a new article in EPL (Europhysics Letters) turns the tables.  Pádraig Mac Carron and Ralph Kenna from Coventry University performed detailed text analyses of the Iliad, Beowulf and the Táin Bó Cuailnge and found that the interactions between the characters in all three myths were consistent with those seen in real-life social networks. Taking this further, the researchers compared the myths to four known works of fiction -- Les Misérables, Richard III, Fellowship of the Ring, and Harry Potter -- and found clear differences.

How might real dogs react to robotic dogs? 

The Sony Corporation has been investigating. Researchers at its Computer Science Laboratory in Paris, which “… engages in fundamental research in cutting edge areas of science that are relevant for pushing the state of the art in computing.” tested the ground by exposing real dogs to AIBO – their now-famous computer-controlled semi-autonomous dog-bot.

Null results are important in science, but that doesn't mean scientists want other people to see theirs. The reason is obvious: competition.  If one group has a null result and another group is working on something similar, they potentially give the competitor a shortcut by publishing a negative result.

So it goes in just about every field. The food industry has its own null results, but they can be a lot more expensive.  The failure rate of new product launches is a shocking (to outsiders) 50%. It seems shocking because these are experts, armed with expensive demographic analyses and psychological information on the marketplace. They should know what people want.

Defense Advanced Research Projects Agency (DARPA) and the National Institutes of Health (NIH) are teaming up to provide $32 million for development of a technology platform that will mimic human physiological systems in the laboratory, using an array of integrated, interchangeable engineered human tissue constructs - a human body on a chip.

The new program is called “Barrier-Immune-Organ: MIcrophysiology, Microenvironment Engineered TIssue Construct Systems” (BIO-MIMETICS) and includes the Department of Biological Engineering at MIT, the Charles Stark Draper Laboratory, MatTek Corp. and Zyoxel Ltd.

Is ‘a pair’ big enough to be called ‘a group’? The tricky subject of dyads has recently been causing considerable professorial debate in the journal ‘Small Group Research’. (Note: the word ‘dyad ‘ is derived from the Greek ‘dýo’, meaning ‘two’.)

In the 1990s, life was simpler for environmentalists.  Crippling the logging industry was all that was needed to protect trees and birds.  

But, as in abortion or gun control, you have to sue everyone or you can sue no one and even responsible logging and clearing brush was stopped by environmental lawsuits and as a result, wildfires have become far more frequent and far more devastating.  Now add a new wrinkle - no logging is leading to more global warming.

How will the Universe end?  And when? It's been speculation in religion and philosophy since man realized he was special.  Can physics offer anything new?

Let's go to the Dark Energy hypotheses and see.  1998 really messed us up, theoretically. Until then, we knew the Universe had to slow down - well, theoretically.  But then the Hubble showed us truly distant supernovae and we got the uncomfortable reality that the Universe was actually expanding more slowly in the past than it is now.  That meant gravity has not been slowing Universal expansion, it has been accelerating. 

Slowly but surely, because it is a good idea, the Quantum Randi Challenge (QRC) generates interest behind the curtains. Some think that because of this, it is all over, but they are mistaken. Several researchers wanted to properly quote the QRC despite of it finding still no support by ‘professional’ journals on the grounds that it is “extremely important but just not quite right for our fine publication”.
