New research reveals a safe path to overcoming food allergies for older children and others who can't risk consuming allergens orally to build up their resistance. It's called sublingual immunotherapy (SLIT), and it involves placing smaller amounts of food allergens under the tongue. A study has found SLIT to be as safe and effective for high-risk older children and adolescents as oral immunotherapy is for preschoolers.
Researchershave found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris.
The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response through lymphatic vessels along the optic nerve.
Chemists fill a major gap in origin-of-life theories.
Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Scientists uncover the mechanism by which cells mark the protein cGAS for degradation, which is critical in preventing the immune system from mistakenly attacking the body's own tissues.
Scientists may have discovered a new way to test for autism by measuring how children's eyes move when they turn their heads.
Researchers identified environmental factors that explain why reports of Unidentified Anomalous Phenomena (UAP) are more common in certain regions of the country. Most sightings occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding the environmental context of these sightings will make it easier to find explanations for their occurrence and help identify truly anomalous objects that may be a legitimate threat.
Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.
Chemistry in the ground affect how many kids wild animals have Areas with more copper and selenium in the ground lead to higher reproductive success in wild musk oxen in Greenland.
Organic materials discovered on Mars may have originated from atmospheric formaldehyde, according to new research, marking a step forward in our understanding of the possibility of past life on the Red Planet.
Researchers have developed a microporous covalent organic framework with dense donor-acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide through the photosynthesis process with water and air.
More frequent use of cannabis was associated with higher odds of adverse cardiovascular outcomes, finds new study.
Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more.
Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.
Engineers have unveiled an encodable multifunctional material that can dynamically tune its shape and mechanical properties in real time.
High levels of air pollution can affect teams doing complex tasks, which holds implications for emerging economies.
According to new research, sitting for long hours without breaks increases risk of early death.
New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Stimulating a key brain rhythm with light and sound increases peptide release from interneurons, driving clearance of Alzheimer's protein via the brain's glymphatic system, new study suggests.
