Astronomers find evidence for most powerful pulsar in distant galaxy
Astronomers analyzing data from the VLA Sky Survey (VLASS) have discovered one of the youngest known neutron stars — the superdense remnant of a massive star that exploded as a supernova. Images from the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) indicate that bright radio emission powered by the spinning pulsar’s magnetic […]
Higher wheat yields and protein content on the horizon
A team of international researchers has discovered a way to produce higher quality wheat. The scientists from the University of Adelaide and the UK’s John Innes Centre have identified a genetic driver that improves yield traits in wheat, which unexpectedly can also lead to increasing protein content by up to 25 per cent. “Little is […]
Sampling the deep graveyard of Earth’s earliest crust
In an international collaboration, Earth scientists at the University of Cologne and Freie Universität Berlin discovered that some magmas on Earth, which made their way through the deep terrestrial mantle and erupted at Earth’s surface, originate from mantle portions that contain remnants of Earth’s earliest crust. This ancient material must have been buried in a […]
Newly identified cell type could be the key to restoring damaged salivary glands: Scientists make fundamental advance in understanding salivary gland biology
Scientists at Scripps Research and the National Institute of Dental and Craniofacial Research have discovered a special type of cell that resides in salivary glands and is likely crucial for oral health. As the researchers described in Cell Reports on April 12, 2022, the new type of salivary gland cell called “ionocyte” that works to […]
Researchers have uncovered a regulator of body weight that could lead to new treatments for metabolic disorders
Yale scientists uncover key regulator of body weight. Yale scientists have discovered that a protein known as augmentor-alpha regulates body weight in mice, an insight that could lead to new treatments for metabolic disorders. The findings were published April 11 in the Proceedings of the National Academy of Sciences. The research team decided to take […]
Chemical compound promotes healthy aging, study finds: BAM15 helped geriatric mice with obesity add muscle, strength and energy while losing fat
A recently discovered chemical compound helped elderly mice with obesity lose fat and weight, add muscle and strength, reduce age-related inflammation and increase physical activity, a new study shows. The study, published in the Journal of Cachexia, Sarcopenia and Muscle, provides the first evidence that BAM15, a mitochondrial uncoupler, prevents sarcopenic obesity, or age-related muscle […]
Genetic ‘hotspots’ that speed up and slow down brain aging could provide new targets for Alzheimer’s drugs
Researchers from a USC-led consortium have discovered 15 “hotspots” in the genome that either speed up brain aging or slow it down — a finding that could provide new drug targets to resist Alzheimer’s disease and other degenerative brain disorders, as well as developmental delays. The research appears online today in Nature Neuroscience. “The big […]
Researchers discover source of super-fast electron ‘rain’: The downpours, which can affect satellites and space travel, are caused by electromagnetic whistler waves, scientists say
UCLA scientists have discovered a new source of super-fast, energetic electrons raining down on Earth, a phenomenon that contributes to the colorful aurora borealis but also poses hazards to satellites, spacecraft and astronauts. The researchers observed unexpected, rapid “electron precipitation” from low-Earth orbit using the ELFIN mission, a pair of tiny satellites built and operated […]
New Fermi arcs could provide a new path for electronics
Newly discovered Fermi arcs that can be controlled through magnetism could be the future of electronics based on electron spins. These new Fermi arcs were discovered by a team of researchers from Ames Laboratory and Iowa State University, as well as collaborators from the United States, Germany, and the United Kingdom. During their investigation of […]
Researchers discover that anti-malaria drugs can fight pulmonary disease
A research team at Colorado State University has discovered that drugs used to treat malaria are also effective at treating a pulmonary disease similar to tuberculosis. Their findings were featured on the cover of the Feb. 23 issue of Science Translational Medicine. The study is a significant development in the fight against infections caused by […]
