Lightning might not strike twice, but black holes apparently do. An international group of researchers led by Tel Aviv University astronomers observed a flare caused when a star falls onto a black hole and is destroyed. Surprisingly, this flare occurred about two years after a nearly identical flare named AT…
New research led by the University of Victoria (UVic) has illuminated a significant and previously unrecognized source of seismic hazard for the Yukon Territory of northwestern Canada. The Tintina fault is a major geologic fault approximately 1,000 km long that trends northwestward across the entire territory. It has slipped laterally…
In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a “neurobiotic sense,” a newly identified system that lets the brain respond in real time to signals from microbes living in our gut. The new research, led by Duke University School of…
A new article appearing in the current issue of the peer-reviewed Journal of Agriculture and Food Chemistry explores the concept of “superfoods” and makes a case that fresh grapes have earned what should be a prominent position in the superfood family. The author, leading resveratrol and cancer researcher John M.…
Cancer cells and tumors do not exist in a vacuum. Far from the isolation and self-sufficiency of the fictional Wakanda, tumors develop in and alter the nearby milieu of immune cells, connective tissue, blood vessels and a sea of proteins and carbohydrates that provide structure and other supportive functions. Cancer…
McGill University researchers have developed and are licensing a digital tool to help safely reduce patients’ use of medications that may be unnecessary or even harmful to them. When clinicians review a patient’s file, MedSafer flags potentially inappropriate medications. In a new clinical trial, the software helped deprescribe such medications…
When given nutritionally matched diets, participants lost twice as much weight eating minimally processed foods compared to ultra-processed foods, suggesting that cutting down on processing could help to sustain a healthy weight long term, finds a new clinical trial led by researchers at UCL and UCLH. The study, published in…
A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs — including spinosaurs and allosaurs — had much weaker bites and instead…
A team of Chinese researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences has developed two new genome editing technologies, known collectively as Programmable Chromosome Engineering (PCE) systems. The study, published online in Cell on August 4, achieves multiple…
Johns Hopkins University researchers have grown a novel whole-brain organoid, complete with neural tissues and rudimentary blood vessels — an advance that could usher in a new era of research into neuropsychiatric disorders such as autism. “We’ve made the next generation of brain organoids,” said lead author Annie Kathuria, an…
The brain’s health depends on more than just its neurons. A complex network of blood vessels and immune cells acts as the brain’s dedicated guardians — controlling what enters, cleaning up waste, and protecting it from threats by forming the blood-brain barrier. A new study from Gladstone Institutes and UC…
Paleontologists have identified a new species of ancient marine reptile from Germany’s world-renowned Posidonia Shale fossil beds, expanding our understanding of prehistoric ocean ecosystems that existed nearly 183 million years ago. The newly classified species, named Plesionectes longicollum (“long-necked near-swimmer”), represents a previously unknown type of plesiosauroid — the group…
Rich with detail, the spiral galaxy NGC 1309 shines in this NASA/ESA Hubble Space Telescope Picture of the Week. NGC 1309 is situated about 100 million light-years away in the constellation Eridanus. This stunning Hubble image encompasses NGC 1309’s bluish stars, dark brown gas clouds and pearly white centre, as…
Following a successful launch on July 30, the NISAR satellite will orbit Earth for at least three years, using its sophisticated radar systems to scan nearly all the planet’s land and ice surfaces twice every 12 days. NASA and the Indian Space Research Organisation (ISRO) will jointly operate the spacecraft…
Some butterflies can smell others of the same species, allowing them to identify each other in areas where multiple species all look the same, new research finds. A large international team has genetically mapped glasswing butterflies found across Central and South America, rewriting the evolutionary tree and highlighting six new…
Florida’s Avon Park bombing range is teeming with life. Over 40 at-risk species occupy this 106,000-acre expanse used by the U.S. Air Force for training exercises. Conservation biologists from Michigan State University are using the range to test something other than weapons: innovative strategies to save threatened species. Using decades’…
Mass General Brigham investigators led a nationwide study that found that financial hardship, food insecurity, lack of healthcare access, and other social risk factors are linked to higher risks of long COVID. Long COVID includes a wide range of symptoms that present or persist three or more months after SARS-CoV-2…
Lupus is a “classic” autoimmune disease. It causes the immune system’s first-line viral defenses — known as interferons — to attack the body. Nearly every organ is at risk, leading to conditions like kidney and heart disease. But unlike many other autoimmune or chronic illnesses, lupus can improve as patients…
Head and neck squamous cell carcinomas (HNSCC) are a group of cancers that affect cells in and around our mouth and nose. With 890,000 new cases and 450,000 deaths annually, HNSCC accounts for roughly 4.5% of cancer diagnoses and deaths worldwide. Treatment options for HNSCC are very limited, so nearly…
Researchers from the University of Adelaide, New Zealand’s Manaaki Whenua-Landcare Research and University of Auckland have discovered that more than 80 per cent of parasites detected in kākāpō poo prior to the 1990s are no longer present in contemporary populations. The project used ancient DNA and microscopic techniques to sample…
Crystals and glasses have opposite heat-conduction properties, which play a pivotal role in a variety of technologies. These range from the miniaturization and efficiency of electronic devices to waste-heat recovery systems, as well as the lifespan of thermal shields for aerospace applications. The problem of optimizing the performance and durability…
NASA’s largest interplanetary probe tested its radar during a Mars flyby. The results include a detailed image and bode well for the mission at Jupiter’s moon Europa. As it soared past Mars in March, NASA’s Europa Clipper conducted a critical radar test that had been impossible to accomplish on Earth.…
Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had cooled down enough for the first elements to form, primarily hydrogen and helium. These were still completely ionized at this…
Macquarie University astronomers have tracked an extreme planet’s orbital decay, confirming it is spiralling towards its star in a cosmic death dance that could end in three possible ways. The ultra-hot Jupiter exoplanet TOI-2109b, located 870 light-years from Earth, completes an orbit around its star in just 16 hours –…
A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar system. The research shows that cosmic rays may not only be harmless in certain environments but…
A frog croaks from a walking trail. A hiker snaps a photo and uploads it to iNaturalist. That single act — one person, one amphibian and one click — feeds into a growing global dataset that scientists now use to map shifting species ranges, detect invasive threats and even discover…
While chemotherapy remains a cornerstone of lung cancer treatment, it often weakens the immune system it relies on for long-term control. Now, researchers have found a way to turn this weakness into strength — by transplanting healthy mitochondria into the tumor environment. In advanced non-small cell lung cancer (NSCLC), combining…
Researchers have demonstrated a novel vaccine delivery method in an animal model, using dental floss to introduce vaccine via the tissue between the teeth and gums. The testing found that the new technique stimulates the production of antibodies in mucosal surfaces, such as the lining of the nose and lungs.…
Did you know that patients with post traumatic stress disorder (PTSD) often struggle to forget traumatic memories, even long after the danger has passed? This failure to extinguish fear memories has long puzzled scientists and posed a major hurdle for treatment, especially since current medications targeting serotonin receptors offer limited…
Three studies presented recently at the Society of NeuroInterventional Surgery’s (SNIS) 22nd Annual Meeting discussed whether using GLP-1 inhibitors could lessen the impacts of stroke and related brain injuries or reduce the risk of stroke altogether. These medications, which lower blood sugar and often cause weight loss, are commonly prescribed for…
