Nerve cells soldered to semiconductors cross computing with neuroscience
Scientists in the United States are soldering nerve cells to semiconductors. Christine Schmidt and colleagues from the University of Texas at Austin use a sliver of protein to connect neurons and tiny crystals of semiconductors called quantum dots 1 .
This cross between biology and electronics could have useful applications, including the manufacture of prosthetics operated directly by a
A gene may protect people against variant Creutzfeldt-Jakob disease.
People who lack a gene involved in immune responses may be three times more likely to suffer from variant Creutzfeldt-Jakob disease (vCJD), a new study suggests1. The result, if borne out in larger studies, could point researchers toward therapies for the incurable brain disease.
vCJD is thought to occur when people are exposed to misshapen prion proteins from cows with bovine spongiform encephalopathy – B
You would be forgiven for underestimating the intelligence of sheep, considering that their daily activities revolve around grazing. But research reported in the current issue of Nature indicates that, in fact, sheep possess more smarts than previously thought.
Keith Kendrick and colleagues at the Babraham Institute in Cambridge, England, investigated the sheep’s ability to distinguish and remember faces of both other sheep and humans. Presenting 20 sheep with pictures of 25 pairs of sheep
Ultra-minaturized electrical components could shrink supercomputers.
Researchers in the Netherlands and the United States have constructed simple computer circuits with electrical components many times smaller than those on commercial silicon chips 1 , 2 . These ultra-minaturized logic circuits hold out the prospect of hand-held computers as powerful as today’s state-of-the-art supercomputers.

It’s an enduring enigma in paleoanthropology: when and where did modern human behavior arise? The fossil record suggests that anatomically modern humans appeared in Africa sometime between 150,000 and 100,000 years ago. Yet the earliest convincing indications of behavioral modernity in our species, archaeologists have argued, date to tens of thousands of years later and have turned up in Europe, not Africa. With that in mind, some theorists posited that modern behavior blossomed late and rather sudd
Our brains use angular measurements to decide how far away objects are.
Even if trigonometry wasn’t your strong suit in school, your brain uses it constantly. You judge distance by measuring the angle between the ground and your line of sight to an object, a new study shows. The finding could improve the design of robots and artificial vision systems 1 .
Volunteers who looked through prisms that increased this angle thought objects were closer than they reall
