The detection of tissue-damaging pungent chemicals like those found in wasabi, tear gas and cigarette smoke is called chemical nociception. It’s different than either taste or smell, and according to recent phylogenetics research, this defensive sensor has been conserved across 500 million years of evolution.

Forensic scientists may soon have a valuable new item in their toolkits—a way to identify individuals using unique, telltale types of hand bacteria left behind on objects like keyboards and computer mice, says a new Univ. of Colorado at Boulder study.

Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals, which is most therapies rely on drugs that block chemical signals. Scientists can now show, however, for the first time, that direct physical force can also change the way cellular proteins conduct chemical activity.

Scientists at the Georgia Institute of Technology have discovered that small molecules could have acted as “molecular midwives” in helping the building blocks of life’s genetic material form long chains and may have assisted in selecting the base pairs of the DNA double helix.

DNA may provide the blueprint for life, but scientists are learning more about the role of a chemical code that governs the way that blueprint is read. Univ. of Wisconsin-Madison researchers have developed a new technique for observing the proteins that operate by that controlling code—called the epigenome—and assembled a library of interactions between the proteins and key positions on packets of DNA.

Researchers from the Arizona State Univ. have helped advance understanding about the antibacterial activity of clay minerals and their ability to kill what the best antibiotics on the market can't touch.

A Univ. of Calgary chemistry professor is a step closer to helping solve a complex problem in nanotechnology: the impact nanoparticles have on human health and the environment.

Like silkworm moths, butterflies, and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, Univ. of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery.

A new technique to study protein dynamics in living cells has been created by a team of Univ. of Illinois scientists, and evidence yielded from the new method indicates that an in vivo environment strongly modulates a protein’s stability and folding rate.

Researchers at North Carolina Univ. have developed a “metal foam” that has a similar elasticity to bone, which could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, such as titanium.
