Oldest-known arm bone found in Pennsylvania

...use it represents a part of the anatomy where many functional changes were taking place. "It's a mosaic of primitive fish and derived amphibian," said Shubin, lead author of the paper. This integral piece of the evolutionary puzzle not only shares features with primitive fish fins, but also has characteristics ...

Fat hormone leptin alters brain architecture and activity, which in turn drives feeding behavior

...s suggest that these leptin-induced structural and functional changes are responsible for changes in the animal's behavior, too. Six hours after administering leptin to obese mice, changes could be seen in their synaptic connections. Forty-eight hours later, they were eating less and at 12 days the mice had lo...

NJIT chemists pave way for cheap, usable field test for polluted, toxic, water, air, food

... Miniaturization using nanotechnology yields many functional and economical benefits because of the reduction of a necessary sample size, the decrease in reagent consumption and the lower costs of mass production. However, scientists cannot sacrifice results to create alternatives. "Yes, the idea behind ...

NIST-led research de-mystifies origins of 'junk' DNA

...own function) that it takes up more space than the functional parts. Much of this junk consists of "introns," which appear as interruptions plopped down in the middle of genes. Discovered in the 1970s, introns mystify scientists but are readily accounted for by cells: when the cellular machinery transcribes a g...

New tumor suppressor may play important role in deadly brain tumors

...ional Institutes of Health," says Garkavtsev. "Its functional role in the prevention of tumor progression had not been investigated. When we found that malignant gliomas have strikingly lower levels of ING4 and knowing that ING4 regulates angiogenesis, this sparked interest toward potential targets that were in...

Researchers confirm novel form of the Rett syndrome protein

...s interesting and raises questions about potential functional differences between the two proteins," said Zoghbi. "Currently about 15 % of patients with a clinical diagnosis of RTT are testing negative for mutations in the MECP2 gene. This development may help to further identify mutations in exon 1. Incorporat...

The arousal difficulties may result in behavioral disturbances and meltdowns from being over-aroused and not being able to appropriately calm down when needed." These findings also help illuminate a somewhat controversial area...

MGH research team grows long-lasting blood vessels

...successfully induced the growth of new networks of functional blood vessels in mice. In the March 11 issue of Nature, the team from the Steele Laboratory in the MGH Department of Radiation Therapy describes how their technique led to the growth of long-lasting blood vessels without the need for genetic manipul...

McGill scientists publish detailed picture of how nutrients and other molecules get into cells

...ructions for making the proteins. Proteins do the functional work in the cell and are much more complex than DNA. The roughly 30,000 human genes lead to more than three hundred thousand different proteins. The ability to rapidly and globally detect proteins represents the next step in biology. Revolutions i...
