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…
Engineers from RMIT University, Australia, have produced a new type of 3D-printed titanium that’s about a third cheaper than commonly used titanium alloys. The team used readily available and cheaper alternative materials to replace the increasingly expensive vanadium. RMIT has filed a provisional patent on their innovative approach, which has…
Society has long struggled with petroleum-derived plastic pollution, and awareness of microplastics’ detrimental effects on food and water supplies adds further pressure. In response, researchers have been developing biodegradable versions of traditional plastics, or “bioplastics.” However, current bioplastics face challenges as well: Current versions are not as strong as petrochemical-based…
Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers led by Abubakar Fadul from the Max Planck Institute for Astronomy (MPIA) has discovered complex organic molecules – including the first tentative detection of ethylene glycol and glycolonitrile – in the protoplanetary disc of the outbursting protostar V883 Orionis.…
The solar atmosphere, or corona, is far hotter than the Sun’s surface, a paradox that has puzzled scientists for decades. Furthermore, the constant outflow of plasma and magnetic fields from the Sun, known as the solar wind, is accelerated to incredible speeds. Turbulent dissipation – the process by which mechanical…
Climate interventions are accelerating in our oceans – but without responsible governance, they could do more harm than good, according to new research. Coral bleaching, rising sea levels, and biodiversity loss are no longer distant threats – they are unfolding now, with profound consequences for marine ecosystems and the communities…
Terrestrial plants drove an increase in global photosynthesis between 2003 and 2021, a trend partially offset by a weak decline in photosynthesis — the process of using sunlight to make food — among marine algae, according to a new study published in Nature Climate Change on August 1. The findings…
As early humans spread from lush African forests into grasslands, their need for ready sources of energy led them to develop a taste for grassy plants, especially grains and the starchy plant tissue hidden underground. But a new Dartmouth-led study shows that hominins began feasting on these carbohydrate-rich foods before…
A research team from Kumamoto University has made a groundbreaking discovery that reveals how the human T-cell leukemia virus type 1 (HTLV-1) silently persists in the body, potentially laying the foundation for new therapeutic approaches. Their findings, published on May 13, 2025, in Nature Microbiology, identify a previously unknown genetic…
The earliest warning signs of multiple sclerosis (MS) may emerge more than a decade before the first classical neurological symptoms occur, according to new research from the University of British Columbia. Published on August 1 in JAMA Network Open, the study analyzed the health records of more than 12,000 people in…
Scientific breakthroughs in one disease don’t always shed light on treating other diseases. But that’s been the surprising journey of one Mayo Clinic research team. After identifying a sugar molecule that cancer cells use on their surfaces to hide from the immune system, the researchers have found the same molecule…
Researchers from New Jersey Institute of Technology (NJIT) have used artificial intelligence to tackle a critical problem facing the future of energy storage: finding affordable, sustainable alternatives to lithium-ion batteries. In research published in Cell Reports Physical Science, the NJIT team led by Professor Dibakar Datta successfully applied generative AI…
Most stars in the Universe exist in binary or multiple star systems, where the presence of close-in companion stars in such systems can adversely influence the formation and orbital stability of planets around one of the stars. An international team of astrophysicists led by Professor Man Hoi LEE from the…
MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of light. They also happen to confirm that Albert Einstein was wrong about this particular quantum scenario. The experiment in question is…
