Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well a.....»»
Study sheds light on how antibiotic "Velcro" kills bacteria
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro form a bond......»»

Appropriate exercise is an important part of crew health during space missions
Future missions to the moon and Mars must address many challenges, including preventing loss of bone and muscle tissue in astronauts. Research on the International Space Station is helping to address this challenge......»»
Phycologists discover what makes some brown algae shimmer and others not
Compartments of consistently sized, tightly packed microspheres are what makes some brown algae shimmer like opal. The Kobe University discovery not only sheds light on the mechanism behind the alga's structural coloration, it is also the first to sp.....»»
As bird flu spreads to dairy cows, Minnesota"s raptors show signs of building remarkable immunity
A little barred owl looked up from the crux of Dana Franzen-Klein's elbow, stared the veterinarian in the eye and, in as tough and menacing of a posture as he could muster, clicked his beak. The injured bird was a baby, maybe a month old. His click w.....»»
Bacterial proteins shed light on antiviral immunity
A unique collaboration between two UT Southwestern Medical Center labs—one that studies bacteria and another that studies viruses—has identified two immune proteins that appear key to fighting infections. The findings, published in PLOS Pathogens.....»»
U.S. Supreme Court backs consumer finance watchdog agency"s funding mechanism
Many conservatives and their Republican allies have portrayed the CFPB as part of an overbearing "administrative state," the network of agencies responsible for the array of federal regulations affecting businesses and individuals......»»
Research identifies mechanism behind drug resistance in malaria parasite
Collaborating researchers have discovered a link between malaria parasites' ability to develop resistance to antimalarial drugs—specifically artemisinin (ART)—through a cellular process called transfer ribonucleic acid (tRNA) modification. tRNA m.....»»
