Shining a light on helical polymers

Due to their singular properties and the functionality attributed to their unique scaffolding, helical polymers are of particular interest to the scientific community. There are specific points along the polymer chain of ...

A new way to assemble cells into 3-D microtissues

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory can now control how cells connect with one another in vitro and assemble themselves into three-dimensional, multicellular microtissues. The ...

Turning glass into clay

The magic mineral and microbial processes that transform volcanic glass into clay have been identified, adding important knowledge to how clay is formed.

Scientists discover how chemical repellants trip up insects

Fire up the citronella-scented tiki torches, and slather on the DEET: Everybody knows these simple precautions repel insects, notably mosquitoes, whose bites not only itch and irritate, but also transmit diseases such as ...

All eyes on retinal degeneration

Research by Johns Hopkins sensory biologists studying fruit flies, has revealed a critical step in fly vision. Humans with problems in this same step suffer retinal dystrophies, which manifest as visual defects ranging from ...

Computer simulations reveal the energy landscape of ion channels

Every cell of our body is separated from its environment by a lipid bilayer. In order to maintain their biological function and to transduce signals, special proteins, so called ion channels, are embedded in the membrane. ...

Drug side effects examined

Yellow vision, pseudo-pulmonary obstruction, involuntary body movements, respiratory paralysis. These are some of the 1,600 known side effects (SEs) produced by drugs. Adverse effects are one of the main causes of hospital ...
