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.

Duke Univ. researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.

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.

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of scientists from Houston's Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs.

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.

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.

Agilent Technologies Inc. announced a system that speeds and simplifies the use of DNA to identify fish species in food products, making this technique feasible for routine verification of seafood labeling and detecting species substitutions.

An extremely small RNA molecule created by a Univ. of Colorado at Boulder team can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward understanding "the very origin of Earthly life," the lead researcher contends.
