Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel, a water-based gel material, made from silk proteins and a plant-derived compound. In laboratory tests, the material promoted complete wound closure within 72 hours, suggesting
A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise: it helped reduce body fat while preserving valuable muscle mass. While moderate and low-intensity workouts also led
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" was simply doing something ordinary that many stars
Astronomers have finally cracked the mystery of the famous “Pink Planet,” a strange world 57 light-years away that has puzzled scientists for more than a decade. Using the James Webb Space Telescope, researchers discovered that its atmosphere contains water vapor, methane,
One year ago, on July 1, 2025, astronomers discovered a fascinating new object moving through the solar system. Detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS), the object was quickly recognized as something special.
Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson’s disease. People exposed to the chemical near their homes were more than twice as likely to develop the condition. Laboratory studies showed that
A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely related to the earliest land plants, researchers have
The study, by researchers Chase Foster (King's College London) and Jeffry Frieden (Columbia University), analyzed 134 national elections in 16 countries between 1990 and 2021, alongside data from 11 waves of the European Social Survey. The research is published in the journal
Australia will expand shark-spotting drone coverage year-round at beaches across Sydney and beyond from July 1, authorities said Sunday, following a rise in attacks and sightings.
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, one to clean the wound and one to support recovery.
NASA is racing to save an aging telescope from falling back to Earth with a daring rescue mission.
The World Health Organization said Sunday that more than 1,300 excess deaths had been recorded in Europe since June 21 in connection with the record-breaking heat wave roasting much of the continent.
When I was a school social worker, a teary-eyed father once came to the school to tell his 4-year-old daughter's teacher that the child's mother had been in an accident. He did not speak to his child as she looked on, but simply relayed pickup arrangements to the teacher before
For decades, scientists have searched for a clear link between the sun's explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see
Plants that become invasive may owe their success to an advantage shaped long before they arrive, according to new research led by King's College London.
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at the center of a visible galaxy. The paper outlining this
Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically
Human-caused climate change is "unequivocally" responsible for the intensity of a record-breaking heat wave scorching Europe, scientists said Friday.
A field guide to the space rocks you might see streaking across the night sky
Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads. Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled
Teens who use cannabis may face a substantially greater risk of developing serious mental health conditions, including psychotic and bipolar disorders, according to a study of more than 463,000 adolescents. Researchers found cannabis use often preceded these diagnoses by nearly
Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath Yellowstone, generating magma closer to the surface. This process helps
A surprising ecological makeover unfolded when mountain lions began frequenting a small preserve south of San Francisco. Deer activity dropped, plants recovered, and shifts among predators like coyotes, bobcats, and foxes followed. The study shows that powerful “trophic
Baboons are one of the most widespread of Africa's primate groups. They range across sub-Saharan Africa and into the Arabian Peninsula. Baboons' ability to spread across such a vast geographic area is based on their great ecological adaptability and dietary flexibility. This
Researchers have identified a vitamin B12–based compound that can cross the blood-brain barrier and home in on glioblastoma tumors. In animal studies, the compound accumulated preferentially in tumor tissue and delivered sustained nitric oxide directly to cancer cells. It also
Greater agility in the sales system—that is, a company's ability to rapidly adapt its sales channels to changing market conditions—is associated with higher operating profit, but only under certain conditions. That is the result of an observational, survey-based study involving
A University of Alberta research team has designed a promising alternative for treating antimicrobial-resistant infections, a pressing global health issue. In a paper recently published in Cell Biomaterials, the team describes preclinical testing results for its human-derived
A chemical analysis of residential soils and ash around California homes burned by the Eaton and Palisades wildfires in early 2025 revealed wide variation in contamination by potentially harmful elements, including lead, according to a study published in Environmental Science
From "harmless" white lies to infidelity, dishonesty in romantic relationships is a complex phenomenon that takes on many forms. New research from the University of Copenhagen shows that while dishonesty between partners often fuels distrust and resentment, it may also, in some
