A study involving more than 11,000 people has found that exposure to light at night is associated with potentially harmful changes in both the structure and function of the heart. The findings were published September 9 in the European Heart Journal. The research was led by Professor Lu Qi of…
A large study across Ontario has found that widely used medications, including statins and iron supplements, can sometimes trigger a chain of additional prescriptions in older adults. In these cases, a side effect from one drug may be mistaken for a new medical condition, prompting treatment with another medication. The…
The development of a nanolaser could mark an early step toward a future in which microchips communicate entirely with particles of light. Researchers at DTU have created a tiny nanolaser that could eventually help make computers, smartphones, and data centers faster while using much less energy. The breakthrough was published…
Quantum computers remain highly vulnerable to errors and tiny disturbances from their surroundings. The longer a quantum operation takes to complete, the more time there is for those errors to build up. Researchers at Chalmers University of Technology in Sweden have now developed a method that can perform a broad…
Summer can be lovely – until a wasp turns up. Whether they present as an irritating picnic visitor or an uninvited loft guest, common social wasps are as much a part of our summer as festivals, sun cream and the growing despair of how to entertain children who’ve forgotten how…
Osteoporosis, a condition that weakens bones and increases the risk of fractures, affects millions of people and remains a major challenge for doctors seeking safe treatments that can be used over long periods. In Germany alone, about six million people are affected, most of them women. Because existing therapies can…
University of Maryland researchers have identified a promising new way to treat venomous snakebites by borrowing from snakes’ own natural defenses. Their approach uses toxin-blocking proteins that western diamondback rattlesnakes evolved to protect themselves from venom. By combining specific proteins found in rattlesnake blood, the researchers achieved unusually strong protection…
An international team of scientists has identified more than 1,200 genetic variants associated with the Big Five personality traits. The findings also suggest that many of the same genetic patterns connected to personality are related to a wide range of life outcomes, including health, longevity, education, careers, and income. The…
Glucagon-like peptide-1 receptor agonists (GLP-1RAs), widely used to treat diabetes and support weight loss, may also have benefits for mental health, particularly among people with bipolar disorder, according to new research from Griffith University. Diabetes, obesity, and bipolar disorder frequently occur together and may share some underlying biological mechanisms. According…
A newly identified dinosaur species discovered during construction work in northeastern Brazil is offering fresh clues about how giant dinosaurs spread across ancient continents. The species, named Dasosaurus tocantinensis, is described in a study published in the Journal of Systematic Palaeontology. The animal measured about 20 meters long and lived…
An international team that includes Nobel Prize-winning physicist Professor Sir Roger Penrose has directly observed a long-predicted gravitational effect in a falling quantum object for the first time. The finding shows that a central principle of Einstein’s theory of gravity continues to agree with quantum behavior under the conditions tested.…
New research led by scientists at the University of California, Santa Cruz, is reshaping what is known about Miracinonyx trumani, the extinct North American predator commonly called the American cheetah. Evidence from nuclear paleogenomes and stable isotopes shows that the animal was not actually a cheetah. Instead, it was a…
About one in eight men will be diagnosed with prostate cancer at some point in their lives. Many patients survive the disease, but prostate cancer can sometimes spread to other parts of the body and become metastatic. In the United States, prostate cancer is the second leading cause of cancer…
Starting statin treatment soon after a type 2 diabetes diagnosis was associated with a reduced risk of developing dementia, according to research presented at ESC Congress 2026 and published in The Lancet Regional Health – Europe. As populations age, the number of people living with dementia is expected to increase…
A critically endangered roloway monkey has given birth only months after a pioneering operation spared her from having her foot amputated. Masaya, a 15-year-old roloway monkey living at Chester Zoo, underwent complex surgery last summer after developing a golf-ball-sized mass on her foot. Zoo veterinarians worked with surgeons from the…
The immune system relies on many different types of cells that work together after an injury. Among the earliest to reach damaged tissue are neutrophils, immune cells that were long viewed mainly as a cleanup crew responsible for removing debris. New research from the Becker team shows that some neutrophils…
Liver disease is most often associated with a handful of familiar causes. These include heavy alcohol use, fat accumulation in the liver connected to obesity, diabetes and high cholesterol, as well as infections with hepatitis B or C. But new research suggests that an environmental chemical may deserve more attention…
Could lasting love have a mathematical formula? Researchers who have studied romantic relationships for decades say that the way feelings change over time may follow patterns that can be modeled with surprising precision. Professor Laurent Pujo-Menjouet of the University of Lyon I and other researchers around the world have been…
Archival discoveries, including a long-forgotten 19th-century autobiography, are changing how historians understand Shadrack Byfield, an English veteran of the War of 1812 who buried his own amputated arm and later created a custom prosthesis. Byfield has appeared repeatedly in television documentaries, books, and museum exhibits in the USA and Canada,…
A widely used erectile dysfunction medication may be associated with a greater risk of glaucoma when taken long-term to relieve urinary symptoms caused by an enlarged prostate, according to a large comparative study published online in the British Journal of Ophthalmology. The findings suggest that men who use tadalafil (Cialis)…
The human gut is home to trillions of microorganisms (the microbiome), a vast community that helps shape digestion, immune function and metabolism. Now, researchers led by the University of Vienna have found that many gut bacterial species are more complex than they appear. Using an analytical strategy known as ‘reverse…
Researchers at HZB have taken an important step toward bringing one of quantum physics’ more unusual predictions closer to experimental reality. Fractons, exotic quasiparticles previously predicted in quantum spin liquids using highly generalized gauge field theories, have now also appeared in simulations of a more realistic quantum solid-state model. Quasiparticles…
A major new analysis led by the American Cancer Society (ACS) paints a troubling picture of cancer worldwide while also highlighting how much of the burden could potentially be reduced through prevention, earlier diagnosis, and better access to care. According to Global Cancer Statistics, 2026, nearly 21 million people were…
More than 10,000 people in the United States with chronic liver disease are currently waiting for a liver transplant, yet the supply of donated organs falls far short of demand. Some patients with liver failure also cannot undergo transplantation because they are not healthy enough to withstand the operation. MIT…
Artificial intelligence (AI) and other information and communication technologies (ICTs) are producing and processing data at a scale never seen before. Internet searches, AI-generated images, recommendation systems, scientific simulations, and large language models all depend on enormous amounts of information being created, moved, stored, and analyzed. As AI becomes more…
