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,…
About 65% of U.S. adults report drinking at least one sugar-sweetened beverage each day. New research from the Mass General Brigham Cancer Institute suggests that this common habit may be associated with a higher risk of gastric cancer. The researchers found that people who consumed sugar-sweetened beverages every day were…
Scientists at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences have uncovered molecular evidence that could point to a previously unknown connection between Homo erectus and modern humans. At the same time, the team developed new paleoproteomics techniques that can extract valuable information from…
Paint exposed to the elements does not last forever. A garden fence may need a fresh coat after only a few years because weather has gradually worn the surface down. The same basic problem affects far larger structures, including the Eiffel Tower and the Golden Gate Bridge, which require extensive…
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…
