Math that powers spam filters used to understand how brain learns to move our muscles

...to look at that same spot. The learner’s speed and pattern in adapting its movements matched the experimental results of the monkeys almost perfectly. “We found that this Bayesian model can explain almost all of the phenomena we observe in regard to learning motor movements,” says Shadmehr. Beyond possib...

Ancient DNA traces the woolly mammoth's disappearance

...umbers until even later. In search of a general pattern in the new study, Barnes and Lister’s team looked to the extinct woolly mammoth. What they found, however, was an “interesting pattern, not like those of the other species.” Their genetic data indicate that Siberian mammoths expanded from a small ...

New findings challenge established views on human genome

...cripts extensively overlap one another. This broad pattern of transcription challenges the long-standing view that the human genome consists of a relatively small set of discrete genes, along with a vast amount of so-called junk DNA that is not biologically active. The new data indicate the genome contain...

Reconstructing the biology of extinct species: A new approach

... tie between the semicircular canals and locomotor pattern is evident both within the primates alone and within the entire mammalian sample. "How an animal moves is a basic adaptation," says Walker, an expert in primate locomotion. "Now we have a way to reconstruct how extinct species moved that is compl...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

The researchers speculate that from an evolutionary standpoint, there may be some microbes that are fought better when sleep is disrupted, although clearly not the two microbes they tested in the current study. "We think that is the re...

Dinosaur hearing, listening to muscle noise, quieter cubicles

To sleep, perchance to dream: New insight into melatonin production

...n the middle of the night. Melatonin's expression pattern is mimicked by a protein called AANAT, which is a key enzyme in the melatonin biosynthesis pathway. Dr. Kim and colleagues uncovered the mechanism of rhythmic control of AANAT mRNA translation, and thereby melatonin synthesis. The researchers fou...

"We don't know whether this pattern will hold up for other species or other cities, but people should certainly be looking," said Angilletta, an Associate Professor of Ecology and Organismal Biology. "Ultimately, this research could help us to understand how species will respond to glo...

Deconstructing brain wiring, one neuron at a time

...So, researchers have been trying to figure out the pattern of connections typical of a type of neuron, to see which other cell types they connect with and how those connections are configured. To do this, they need a tracer that can tease apart the chain of directly connecting neurons, identifying them one b...
