First mammalian 'cell phone'

(Phys.org)—Researchers from ETH Zurich have quite literally created a "cell phone": they have reprogrammed mammalian cells in such a way that they can "phone" each other via chemical signals.

New tools developed to unveil mystery of the 'glycome'

Scientists at The Scripps Research Institute have developed chemical compounds that can make key modifications to common sugar molecules ("glycans"), which are found on the surface of all cells in our body. The new study ...

New study reveals basic molecular 'wiring' of stem cells

Despite the promise associated with the therapeutic use of human stem cells, a complete understanding of the mechanisms that control the fundamental question of whether a stem cell becomes a specific cell type within the ...

'Worm speak' uses chemicals to communicate

(PhysOrg.com) -- A species of small, transparent roundworms have a highly evolved language in which they combine chemical fragments to create precise molecular messages that control social behavior, reports a new study from ...

New strategy could lead to dose reduction in X-ray imaging

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach ...

New biosensor benefits from melding of carbon nanotubes, DNA

Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and ...

Nailing down a crucial plant signaling system

Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. ...
