What makes tissue soft and yet so tough

Engineers at ETH Zurich have discovered that soft biological tissue deforms very differently under tension than previously assumed. Their findings are already being put to use in medical research projects.

Study clears way to growing replacement body organs

A discovery involving Monash University scientists promises to pave the way to producing replacement organs for damaged hearts, kidneys and bowels, using patients' own stem cells.

Fish study shows important genome interactions in animal cells

In a new study, researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science examined how the interaction of two genomes in animal cells—the mitochondrial and nuclear genomes—interact ...

Researchers imitate molecular crowding in cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for ...

Safe and ethical ways to edit the human genome

The National Academies of Science and Medicine (NASEM) released a report on Feb. 14 exploring the implications of new technologies that can alter the genome of living organisms, including humans.

GM shares fall on reports of antitrust penalty in China

A Chinese state-run newspaper reported Wednesday that the government will penalize an unidentified U.S. automaker soon for alleged anti-competitive behavior. With signs pointing to General Motors, shares of the Detroit company ...

Nanofiber coating prevents infections of prosthetic joints

In a proof-of-concept study with mice, scientists at The Johns Hopkins University show that a novel coating they made with antibiotic-releasing nanofibers has the potential to better prevent at least some serious bacterial ...
