Eosinophilic esophagitis (EE) is a rapidly rising disorder characterized by severely elevated levels of eosinophils in the esophagus, leading to vomiting and difficulty swallowing. The disease has a familial pattern suggesting genetic or environmental factors, warranting further study.
Research reveals high charges in cloud drops may influence precipitation and study suggests Arctic clouds' structure affects global warming. A new model also proposes ancient snowfall as a source of water for Mars' channels near Tharsis.
Researchers at Duke University Medical Center discovered molecular portals in dendritic spines of neurons that facilitate endocytosis of receptors. This finding reveals a previously unknown level of organization in the brain, with implications for understanding neural connections and memory.
Researchers at NJIT have developed a new compound derived from pine trees that could change the face of green chemistry. The chiral ionic liquid, created through a Diels-Alder reaction, offers non-toxic and cost-efficient methods for pharmaceutical and fine chemical industry processes.
Researchers at UCI are working on a vaccine against melioidosis, caused by B. pseudomallei, a bacterium that thrives in water and can cause severe pneumonia and septic shock. The development of a safe and effective vaccine is crucial to blunt bioterrorism threats.
Researchers found that wastewater treatment plants employing reverse osmosis successfully removed more contaminants, including pharmaceuticals and hormones. This process improves the quality of reused water for irrigation and groundwater recharge.
Researchers discovered a critical link in the molecular pathway that enables the immune system to target invaders with precision. The discovery may also provide new information on lymphoma, a type of leukemia where certain immune cells proliferate uncontrollably.
A recent NCAR study found a significant decrease in frost days worldwide over the last 50 years, with greatest reductions in the western US and Canada. The factors at work are attributed to changes in atmospheric circulation, including increased mild air from the Pacific and cold Canadian air from the east.
Researchers at Boston Children's Hospital have made a breakthrough in understanding how rotavirus enters cells, paving the way for a new and safer vaccine. The study used crystallography and electron microscopy to determine the geometric structure of the virus's surface protein VP4, revealing its entry mechanism.
A new study suggests that endovascular surgery (EVAR) reduces mortality rates by around two-thirds compared to conventional open surgery for large abdominal aortic aneurysms. The study involved over 1000 patients and found that EVAR was associated with lower 30-day mortality rates, but also led to more secondary procedures.
Researchers at Virginia Tech have developed a system that converts light energy from the sun into chemical energy, producing hydrogen gas. The team's molecular machines use light signals to collect and deliver electrons, enabling the production of hydrogen through artificial photosynthesis.
Researchers found that worms seek mates when alone but remain near food sources with potential mates. In cone-only retinas, rod bipolar neurons maintain their morphology and connectivity despite lacking rods, while remaining light-sensitive.
The Delacour's langur is one of the most Critically Endangered primates in the world, with only 300 individuals remaining. Conservation efforts are underway to protect the species, but time is running out, and it may soon become extinct.
Researchers at Harvard Medical School have developed a method to generate potentially hundreds of aminocoumarin variants, which are inhibitors of bacterial type II topoisomerases. The approach uses bacterial enzymes to add different chemical moieties to the coumermycin A1 backbone, resulting in compounds with tailored properties.
Researchers found pronounced nitrogen oxide pollution plumes extending across central Indian Ocean, mainly from Africa and southeast Asia. The study suggests that the Indian Ocean is not always pristine and that feedbacks in atmospheric chemistry can result in downwind regions being highly insensitive to upwind emissions.
Astronomers have discovered a Jupiter-sized gas giant orbiting a star located 500 light-years from Earth. The newly found world circles its star every 3.03 days at a distance of only 4 million miles, much closer and faster than Mercury in our solar system.
A new study challenges the long-held view that high-dose steroids cause bone loss in children. Researchers found no signs of osteoporosis in 60 steroid-sensitive nephrotic syndrome patients, contradicting previous findings in other childhood diseases treated with steroids. Obesity may actually stimulate bone growth and increase bone mass.
Researchers at Temple University are developing metal oxide nanoparticles using ferritin protein to remove toxic metals like Chromium-6 and Technetium-7 from lakes, rivers, and groundwater. The nanoparticles can be activated by visible light, reducing chromium from hexavalent to trivalent, making it easier to filter out.
Using electron-stimulated desorption (ESD), researchers at Georgia Tech demonstrated that hydrochloric acid dissociates quickly upon contact with icy surfaces, even at temperatures below 100 degrees Kelvin. This study provides new insights into atmospheric chemistry and the surface activity of ice crystals.
Researchers found that unicellular organisms are fixing nitrogen at rates up to three times higher than previously reported for the Pacific Ocean. This influx of nitrogen has significant implications for global carbon sequestration and climate regulation.
Researchers will create mechanical systems with one or two motors to accomplish tasks currently done by robots. The goal is to provide a cheaper and lower maintenance alternative for assembly line designers.
Researchers at the University of Illinois have developed a novel polyester lubricant called SHP that improves computer hard drive performance and lasts longer. The lubricant, which has good adhesion properties, shields the disk from damage during contact with the head, allowing for faster reading and writing.
Researchers at Johns Hopkins University have found that riverbank filtration can significantly decrease bacteria and viruses in drinking water, as well as reduce the presence of Giardia and Cryptosporidium. This technique involves passing river water through nearby sediment, which removes impurities and reduces treatment costs.
Dr. Arthur Anker's research on alpheidae, a diverse family of snapping shrimp, has led to the discovery of two new species: Automate hayashii from Hokkaido, Japan, and Bermudacaris australiensis off Western Australia. These finds expand our understanding of this unique family's range and ecological diversity.
Researchers have developed a new hydrogen generator that uses sunflower oil, air, and water vapor to produce hydrogen intermittently. The process reduces dependence on foreign oil and generates fewer pollutants than traditional methods.
A Stanford researcher has devised a method to identify potential drug compounds using a network of over 150,000 home computers and innovative algorithms. The method accurately predicts how well molecules will bind to a given protein, which is crucial in drug development.
The new powder-based vaccine formulation has shown an 83-100% survival rate in rabbits exposed to lethal doses of inhalation anthrax. Initial data indicates improved stability over the liquid version, allowing for stockpiling without refrigeration. Further studies are needed before clinical trials could begin within two to three years.
