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…
Researchers at the University of Warwick have found a striking association between ADHD and digestive health after analyzing data from more than 1.9 million people across 23 studies. Overall, people with ADHD were almost 50% more likely to experience gastrointestinal symptoms than people without ADHD. Some individual conditions showed even…
Quantum mechanics has always challenged our everyday understanding of reality. In the quantum world, particles can exist in a superposition of states, meaning they can occupy multiple possible positions or configurations at the same time. Physicists describe these possibilities mathematically using a wavefunction. That picture is very different from ordinary…
For roughly two centuries, human life expectancy climbed steadily as medicine, sanitation, nutrition, and healthcare improved. More recent research, however, suggests that this long upward trend may now be leveling off in developed countries. If that is the case, the next major challenge may no longer be simply preventing disease,…
Researchers from the University of Sydney, the Baird Institute and Royal Prince Alfred Hospital in Sydney have found that the human heart can produce new muscle cells after a heart attack. The discovery challenges the long-held assumption that heart muscle lost during an attack cannot regenerate and could eventually help…
A new UIC study suggests that time-restricted eating could offer a safe and potentially effective way to improve blood sugar control in adults with Type 1 diabetes. The research was led by kinesiology and nutrition professor Krista Varady, a longtime researcher in the field of intermittent fasting. “This is the…
Earth has an unusually large moon compared with other rocky planets in the solar system, but scientists still do not fully understand how it formed. A new study from researchers at the Southwest Research Institute and the University of Arizona suggests that one long-overlooked factor may have played a major…
T cell receptor therapy, known as TCR therapy, is a form of cancer treatment that genetically modifies immune cells called T cells so they can recognize and attack cancer with high precision. The approach resembles CAR T-cell therapy, but there is an important difference. CAR T-cell therapy can recognize proteins…
DNA carries a negative electrical charge. Because objects with the same charge normally push away from each other, DNA molecules might be expected to repel one another. Yet inside living cells, DNA must sometimes come into close contact and recognize matching sequences. These interactions are essential for processes including genetic…
Researchers have identified four additional sailors from Sir John Franklin’s ill-fated 1845 Arctic expedition, including one man whose identity had remained the subject of debate for more than a century. Anthropologists from the Faculty of Arts at the University of Waterloo led the research, using DNA recovered from skeletal remains…
Look closely at Hokusai’s The Great Wave off Kanagawa, one of Japan’s most famous works of art, and the brilliant whites seem almost painted onto the scene. Yet the white foam of the waves, the snow covering Mount Fuji, and the clouds in the sky contain no white pigment at…
The first moment you look inside a newly discovered ancient tomb is at once exciting and terrifying. I was fortunate to experience this recently as director of an international research team carrying out fieldwork in the Theban necropolis, a Unesco world heritage site near the modern Egyptian city of Luxor.…
Archaeologists from Griffith University have found evidence suggesting that humans were using mind-altering substances much earlier in time than scientists once thought. The research was led by Professor Adam Brumm of Griffith’s Australian Research Centre for Human Evolution (ARCHE), together with ARCHE colleagues Associate Professors Carney Matheson and Michelle Langley.…
On the French Riviera, a tsunami could arrive before a warning reaches people on the beach. In some local scenarios, the first waves could reach shore in under 10 minutes. France’s national warning center, meanwhile, is designed to send its initial alert to authorities within 15 minutes of a potentially…
High cholesterol can quietly damage arteries for years, raising the risk of heart disease and other cardiovascular problems. Now, researchers from the University of Barcelona and the University of Oregon have developed an experimental strategy that could offer a new way to bring cholesterol levels down. The approach targets PCSK9,…
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…
