Molecular motor structural changes imaged

(Phys.org) —The brain's repute took a big hit in 1997 when an IBM supercomputer defeated world chess champion Gary Kasparov in a match reported around the world. But in the second round, the brain is back.

(Phys.org) —In a factory, outside forces dictate the assembly of parts. Robots lift widgets from trays, assemble them and send them on their way. Even though embryos are not factories, theories about embryonic ...

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechan ...

It is rare that an unpublished piece of research or theory remains significant after half a century. It is also a wonderful example of the boundless curiosity of the late Francis Crick. A previously unpublished work by Francis ...

New research by scientists at the University of Massachusetts Medical School shows at the single cell level how an external stimulus sets off a molecular chain reaction in the transparent roundworm C. elegans, a proc ...

(Phys.org) —Molecular motor proteins inside the body, called kinesins, are a lot like the motor in your car. The molecular motors convert stored chemical energy into specific conformational changes, which ...

By day, insects provide the white noise of the South, but the night belongs to the amphibians. In a typical year, the Southern air hangs heavy from the humidity and the sounds of wildlife.

Researchers at Rutgers, The State University of New Jersey, and City University of New York have invented a proprietary new formulation called Visikol that effectively clears organisms to be viewed under microscopes. Visikol ...

Archaeologists have made a discovery in southern subtropical China which could revolutionise thinking about how ancient humans lived in the region.

A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming ...

A new way of valuing ecosystem services, incorporating the local perspective, is the driving force behind a project assessing aquatic ecosystems in highland areas of Asia

Dog parks are a great place to socialize dogs and let them play, but they also have some hidden dangers, according to a Kansas State University veterinarian.
