Beyond batteries: Storing power in a sheet of paper
...ed device, he said. The components are molecularly attached to each other: the carbon nanotube print is embedded in the paper, and the electrolyte is soaked into the paper. The end result is a device that looks, feels, and weighs the same as paper. The creation of this unique nanocomposite paper drew from a...New technology reveals seal behavior

Results are published this week in the journal Proceedings of the National Academy of Sciences. The seals were tagged at the islands of South Georgia, Kerguelen ...Secret life of elephant seals not secret anymore!
Miniature oceanographic sensors attached to southern elephant seals have provided scientists with an unprecedented peek into the secret lives of seals. The measurements reveal in detail where the seals go on their winter feeding trips, where they find food and where they dont, and help ex...In a first, Einstein scientists discover the dynamics of transcription in living mammalian cells
...ew RNA, they saw many cases where enzyme molecules attached and then promptly fell off. One surprising finding was how inefficient the transcription process really is, particularly during its first two stages, says Dr. Singer. It turns out that only one percent of polymerases that bind to the gene actually...How cells change the pace of their steps

They serve as the link between the neurotransmitter binding site and the membrane region where the gate is located, Chen said. The sugar is kind of like a hinge. Its pulling the door open and closed.

...A strand includes a sugar and phosphate "backbone" attached to one of four bases, which encode genetic sequences. The strength of the interactions within individual strands comes largely from the chemical attraction between the stacked bases. But the integrity of double-stranded DNA depends on both the stacki...Bernese Mountain Dogs prone to Borrelia burgdorferi infection

The team used an enzyme-linked immunosorbent assay (ELISA) as well as a Western blot test to see whether the dogs had developed antibodies against B. burgdorferi.

This setup allowed the researchers to measure the position and force on the bead, creating a very precise sensor o...Time-lapse recordings reveal why IVF embryos are more likely to develop into twins
