Some of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere provides new clues about the atmosphere's history.
The risk of blindness caused by spinal fusion, one of the most common surgeries performed in the U.S., has dropped almost three-fold since the late 1990s, according to the largest study of the topic to date.
Proteins that play key roles in the timing of cell division also moonlight in regulating blood sugar levels, researchers have found.
Researchers have described a new genus and species of cavefish from Mexico -- the Oaxaca Cave Sleeper.
Engineers have created a new computer modeling package that people anywhere in the world could use to assess the potential of a stream for small-scale, 'run of river' hydropower, an option to produce electricity that's of special importance in the developing world.
New research shows similarities in the social organization of bees and mammals, and provides insight into the genetics of social behavior for other animals. These findings use sociogenomics -- a field that explores the relationship between social behavior and the genome -- to show strong similarities in socially genetic circuits common in honey bees and mammals.
Scientists have found the first 'fingerprints of healing' for the Antarctic ozone hole. The September ozone hole has shrunk by more than 4 million square kilometers since 2000, when ozone depletion was at its peak.
Plants can grow faster as atmospheric carbon dioxide concentrations increase, but only if they have enough nitrogen or partner with fungi that help them get it, according to new research.
With potentially major implications for the future treatment of autoimmunity and related conditions, scientists have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system. They studied an autoimmune disease called pemphigus vulgaris, a condition in which a patient's own immune cells attack a protein called desmoglein-3 that normally adheres skin cells.
Cell replacement therapies hold promise for many age-related diseases, but efforts to bring treatments to patients have not been very successful -- in large part because the newly derived cells can't integrate efficiently into tissues affected by the ravages of aging. This is poised to change. Researchers have harnessed a naturally occurring anti-inflammatory mechanism that repaired the eye and significantly enhanced the success of retinal regenerative therapies in mice. The results could be particularly significant for macular degeneration.
Aedes aegypti mosquitoes transmit dengue, chikungunya, and Zika viruses. A study reports a new technique that could make one approach to mosquito control -- using Wolbachia bacteria that reduce the mosquitoes' ability to transmit viral pathogens -- a whole lot easier and cheaper to implement and evaluate.
Most adults carry multiple herpesviruses. Following the initial acute infection, these viruses establish life-long infections in their hosts and cause cold sores, keratitis, genital herpes, shingles, infectious mononucleosis, and other diseases. A new study suggests that attacking herpesvirus DNA with CRISPR/Cas9 genome editing technology can suppress virus replication and, in some cases, lead to elimination of the virus.
