Light-controlled reactions at the nanoscale

Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation ...

How equal charges in enzymes control biochemical reactions

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes—the biological catalysts in all living organisms—form ...

Tumble-proof cargo transporter in biological cells

ver wondered how a molecular nanomotor works when repairing DNA or transporting material such as organelles in the cell? Typically, nanomotors move along biopolymer filaments to go about their duties in the cell.  To do ...

Switching DNA functions on and off with light

DNA is the basis of life on earth. The function of DNA is to store all the genetic information an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell. Biochemists ...

World's only dog test for a culprit in 'kennel cough'

The world's first diagnostic test for canine pneumovirus, a unique culprit in "kennel cough"—canine respiratory illness common in shelters and kennels—is now available at Cornell's Animal Health Diagnostic Center (AHDC).

Atmospheric beacons guide NASA scientists in search for life

Some exoplanets shine brighter than others in the search for life beyond the solar system. New NASA research proposes a novel approach to sniffing out exoplanet atmospheres. It takes advantage of frequent stellar storms—which ...

Powerful supercomputer peers into the origin of life

(PhysOrg.com) -- Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are helping scientists unravel how nucleic acids could have contributed to the origins of life.
