Researchers use CRISPR to manipulate social behavior in ants

The gene-editing technology called CRISPR has revolutionized the way that the function of genes is studied. So far, CRISPR has been widely used to precisely modify single-celled organisms and, more importantly, specific types ...

Decoding ants' coat of many odors

It's a waxy layer that covers their bodies and is the source of the complex aromas that ants use to communicate. These odorant blends act like biochemical uniforms, identifying individual ants by caste, colony and species. ...

Study yields insight into the mystery of smell

Researchers at the University of Pittsburgh School of Medicine have uncovered the mechanism underlying a phenomenon in how we smell that has puzzled researchers for decades. In an article appearing online today in the Proceedings ...

Design and enantioselective synthesis of new Cashmeran odorants

When a perfume is said to include Cashmere Wood, it means the typical smell of the odorant Cashmeran. As described in the journal Angewandte Chemie, scientists from Switzerland and Germany have introduced new members in this ...

Chemists discover way nose perceives common class of odors

Biologists claim that humans can perceive and distinguish a trillion different odors, but little is known about the underlying chemical processes involved. Biochemists at The City College of New York have found an unexpected ...

Odor code for food is based on a few volatile substances

(Phys.org) —The actual flavor of a food is experienced through our sense of smell rather than with our tongue. However, of the large number of volatile compounds in foods, only about 230 are involved in the scent, as reported ...

The first insects were not yet able to smell well

An insect's sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at ...

Mosquito sperm have 'sense of smell'

Vanderbilt biologists have discovered that mosquito sperm have a "sense of smell" and that some of same chemicals that the mosquito can smell cause the sperm to swim harder.
