Nuclear clocks would measure time based on changes inside an atom's nucleus, which would make them less sensitive to external disturbances and potentially more accurate than atomic clocks. These clocks could lead to improved timekeeping and navigation, faster internet speeds, and advances in fundamental physics research. Scientists have demonstrated key components of a nuclear clock, such as precise frequency measurements of an energy jump in a thorium-229 nucleus. Read more ›

A new study shines a light on the enormous scale of uncollected rubbish and open burning of plastic waste in the first ever global plastics pollution inventory. Researchers used A.I. to model waste management in more than 50,000 municipalities around the world. This model allowed the team to predict how much waste was generated globally and what happens to it. Read more ›

Researchers have designed, in mice, an approach to minimizing the damage from a spinal cord injury through the use of engineered immune cells. Mice given the treatment had improved recovery from injuries, demonstrating potential for developing the therapy for people. Read more ›

Our risk of developing atherosclerosis -- 'furring' of the arteries -- can begin much earlier in life than was previously thought, highlighting the need to keep cholesterol levels low even when we are young, new research has discovered. Read more ›

The new approach marks a major step forward in the design of AI tools to support clinical decisions in cancer diagnosis, therapy. The model uses features of a tumor's microenvironment to forecast how a patient might respond to therapy and to help inform individualized treatments. The model can expedite the identification of patients not likely to benefit from standard treatments used in some forms of cancer. Read more ›

The most frequently used mpox vaccine provides partial immunity to the disease but isn't always able to prevent severe symptoms or disease transmission. A new vaccine candidate from Moderna, mRNA-1769, more effectively limits symptoms and disease duration in primates that were infected with a lethal strain of the mpox virus when compared to a currently licensed modified vaccinia Ankara (MVA) vaccine.

Immune checkpoint inhibitors are a type of cancer treatment that helps the immune system attack cancer cells more effectively. One of the key proteins involved in this process is Lymphocyte Activation Gene-3 (LAG3), which suppresses the antitumor immune response. Researchers have made an important discovery about LAG3, revealing how it interacts with other proteins to control immune activity. Their study could lead to better cancer treatments by enhancing the effectiveness... Read more ›

Bad behavior often occurs away from home, leading parents to blame and limit contact with peers. However, a new study shows that banning friendships can backfire, worsening behavior instead of improving it. When moms disapprove of their kids' friends in an effort to curb misbehavior, it often alienates the child from their peers, exacerbating the very issues they aimed to prevent. Meddling in friendships can harm a child's social standing... Read more ›

Rain and water in ponds and lakes slowly seeps into the soil, moving through minute cracks to refill underground aquifers. Per- and polyfluoroalkyl substances (PFAS), often described as forever chemicals, can tag along into groundwater that's later removed for drinking. Researchers analyzed water from over 100 wells in Denmark for one particularly persistent PFAS: trifluoroacetate. They report steadily increasing levels of the forever chemical in recent decades.

Chemists offer a new explanation for how collagen in dinosaur bones may have survived millions of years: An atomic-level interaction prevents its bonds from being broken down by water. Read more ›

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the methylation of their genetic material, which endowes these special astrocytes with stem cell properties. In mice, the researchers showed that experimentally induced lack of blood supply in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn... Read more ›

New research addresses the fundamental science necessary to increase the efficiency of nuclear energy. Researchers have now documented the unique chemistry dynamics and structure of high-temperature liquid uranium trichloride salt, a potential nuclear fuel source for next-generation reactors.

Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 times larger than the one that ended the age of the dinosaurs on Earth, and caused one of the biggest impacts with clear traces in the Solar System.

Over billions of years, the universe's stars and galaxies shined their light into space, leaving behind an imperceptibly faint night light known as the cosmic optical background. NASA's New Horizons spacecraft has traveled to the edge of Earth's solar system and captured the most accurate measurement of this glow to date. Read more ›

Despite what we've been led to believe, the timing of evening screen use, rather than the activity itself, negatively impacts youth sleep, a new study has found. Read more ›

The bigmouth buffalo is a fish that's native to Minnesota and known for its longevity. Researchers wanted to find out more about the species, especially how they migrate, spawn, and how often their offspring live into adulthood. Read more ›

Researchers have discovered that inflammation in the gut leaves long-term marks on intestinal stem cells (ISCs) that reduce their ability to heal the intestine, even after inflammation has receded. This is important because it affects ISCs' response to future challenges. Read more ›
