Many medicines are twisted molecules with two mirror image versions, but the body uses only one. Inspired by photosynthetic bacteria, a team built a catalyst that guides chemical reactions toward the right version of twisted molecules. It could lead to more efficient production of some medicines.
Read moreClinician burnout is affecting between one-third and one-half of all of US nurses and physicians, and 45 to 60% of medical students and residents, according to a new report.
Read moreResearchers have uncovered new details about several proteins implicated in tumor growth and metastasis, opening a potential avenue for the development of treatments for diseases such as breast cancer.
Read moreTadpoles that can typically regrow amputated tails or limbs lost their ability to regenerate after researchers blocked the expression of a newly identified gene that is one of the drivers for this regrowth. Furthermore, scientists hypothesize that the loss of appendage regeneration in warm-blooded animals might have been caused by the gain or loss of this gene, dubbed c-Answer, in an ancestor's genome during evolution.
Read moreA new antiviral drug that induces mutations in the genetic material of influenza virus is highly effective in treating influenza infection in animals and human airway tissue and could be a groundbreaking advance in influenza therapy.
Read moreResearchers have presented a swarm of tiny drones that can explore unknown environments completely by themselves. This work forms a significant step in the field of swarm robotics.
Read moreWomen scientists were 21% less likely to author invited commentaries in medical journals during a five-year period than men with similar scientific expertise, seniority, and publication metrics.
Read moreTo inspire advanced robotic technology, researchers have published the most complete description of how flying insects land upside-down.
Read moreSuperbly preserved fossils from Russia cast new and surprising light on one of the earliest tetrapods — the group of animals that made the evolutionary transition from water to land and ultimately became the ancestors not just of amphibians, reptiles, birds and mammals, but of ourselves.
Read moreInvestigators sought to understand the series of events that occur between salt consumption and poor cognition and concluded that lowering salt intake and maintaining healthy blood vessels in the brain may 'stave off' dementia. Accumulation of tau deposits has been implicated in the development of Alzheimer's disease in humans.
