Leanest teens are biggest energy users and consumers

...sue of The International Journal of Obesity. "This allows your child to eat more calories, which encourages more healthy eating habits while remaining in energy balance." Unfortunately, even the leanest of the 661 healthy black and white Augusta teens didn't have great eating habits, researchers note. ...

"And we are delighted that the management of SPOC, whose technology was deve...

Cells selectively absorb short nanotubes

...bes because this renders them soluble in water and allows them to be sorted and separated by length. The researchers then exposed human lung fibroblasts to solutions containing unsorted nanotubes. Regardless of the concentration levels, the cells did not absorb between about one-fourth and one-third of the ...

Penn scientists engineer small molecules to probe proteins deep inside cell membrane

... this approach are a long way off, but this method allows us to now study these interactions that are so fundamental to the way in which cells cooperate to carry out essential functions," says Bennett. "In the future, this knowledge can provide insights for identifying novel drug targets."...

It has applications in ecology, conservation, physiology, palaeontology, amongst other fields, and it will also shed new light on the evolution of our own spe...

Scientists reveal structure of gateways to gene control

... the exact DNA sequences for all these nucleosomes allows us to precisely map their positions across the entire genome," explains Schuster. The map reveals, for the first time, precisely which DNA sequences are part of the control-center's H2A.Z nucleosome for each gene in the yeast genome. Also for the f...

Chromosomal microarray analysis proves accurate

One membrane, many frequencies

...e end, they form a flimsy, net-like structure that allows the membrane to be flexible; on the rigid side, the fibers are densely and uniformly packed. The more rigid a tectorial membrane is, the higher the frequency at which it can vibrate. Thus, the flexible end of the membrane, which should respond to l...

A person will carry a combination of two copies of the protein, one from the mother and one from the father. "If you have the overactive type, you are twice as lik...

LED array signals successful binding of drug-delivery molecules to DNA

...the special molecules successfully bind to DNA. It allows us to do 100 tests per day, instead of one or two, said Karen Brewer, professor of chemistry at Virginia Tech. The research will be presented at the 233rd national meeting of the American Chemical Society in Chicago March 25-29. Pussin and chemis...

Researchers figure out what makes a simple biological clock tick

...ell than it does when it is dephosphorylated. That allows the bioclock to turn various cellular processes on and off. Based on previous research, Johnson and his colleagues had some insight into the role of the two smaller proteins. They knew that when KaiA binds to KaiC the phosphorylation rate increases, ...
