Giant ridges on the surface of landslides on Mars could have formed without ice, challenging their use by some as unequivocal evidence of past ice on the red planet, finds a new study using state-of-the-art satellite data.
Read moreA new study describes a novel approach for purifying rare earth metals, crucial components of technology that require environmentally-damaging mining procedures. By relying on the metal's magnetic fields during the crystallization process, researchers were able to efficiently and selectively separate mixtures of rare earth metals.
Read moreResearchers report the discovery of a protein, P17/PERMIT, that is key to recycling aging and damaged mitochondria. Defective mitochondria are characteristic of a number of age-related diseases, including cancer and Alzheimer's. The MUSC team showed P17/PERMIT transports the machinery that produces ceramide, a molecule that signals old mitochondria for destruction, to the mitochondria. There, it can mass-produce ceramide at the location needed for mitochondrial regulation.
Read moreNew cellular and molecular processes underlying communication between gut microbes and brain cells have been described for the first time.
Read moreMany 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.
