Popular GLP-1 drugs help many people drop tremendous amounts of weight, but the drugs fail to provide a key improvement in heart and lung function essential for long-term good health, University of Virginia experts warn in a new paper. The researchers emphasize that weight loss associated with GLP-1 drugs has many clear health benefits for people with obesity, type 2 diabetes and heart failure, including improving blood-sugar control, short-term cardiorenal benefits and improvements in survival outcomes. But doctors may need to consider recommending exercise programs or develop other approaches, such as nutrition supplements or complementary medications, to help ...

A new high-resolution flood dataset, FloodPlanet, is enhancing satellite-based flood monitoring through more accurate training of deep learning models. By manually labeling inundation data from commercial satellites and aligning them with public sensor imagery, researchers improved flood detection accuracy by up to 15.6%. This work addresses critical limitations in current flood mapping and opens the door for more reliable global inundation response systems. Flooding affects more people globally than any other environmental hazard, yet accurate ...

Recent research shows that your brain doesn’t pay attention in one smooth stream—instead, it switches focus in quick bursts, about 8 times per second. This process, called “attentional sampling,” helps your brain deal with too much information by jumping back and forth between different things you're seeing. It’s kind of like your brain is taking rapid snapshots instead of watching a constant video. And when you need to focus on more than one thing, the rhythm splits to allow focusing on each one around 4 times ...

Photocatalysis, a technology that converts solar energy into chemical reactions, holds immense promise for addressing energy shortages and environmental pollution.

Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disc with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disc spiral. “We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, ...

In the race to develop AI that understands complex images like financial forecasts, medical diagrams and nutrition labels — essential for AI to operate independently in everyday settings — closed-source systems like ChatGPT and Claude currently set the pace. But no one outside their makers knows how those models were trained or what data they used, leaving open-source alternatives scrambling to catch up.  Now, researchers at Penn Engineering and the Allen Institute for AI (Ai2) have developed a new approach to train open-source models: using AI to create scientific figures, charts and tables that teach other AI systems ...

When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration, and chronic inflammation. A new chemical tool developed at UC Riverside interrupts that process, helping preserve DNA before the damage leads to disease. The study, published in the German Chemical Society journal Angewandte Chemie International Edition, focused on mitochondrial DNA, which is separate from the DNA housed in a cell’s nucleus. While nuclear DNA contains the vast majority of the genetic code, mitochondria carry their own smaller genomes that are essential for ...

What if we could prevent people from developing obesity? The World Obesity Federation expects more than half the global population to develop overweight or obesity by 2035. However, treatment strategies such as lifestyle change, surgery and medications are not universally available or effective. By drawing on genetic data from over five million people, an international team of researchers has created a genetic test called a polygenic risk score (PGS) that predicts adulthood obesity already in early childhood. This finding could help to identify children ...

A new commentary published in Nature Communications by Dr James Bradley, Reader in Environmental Science at Queen Mary University of London, and his team reveals a dramatic and concerning shift in the Arctic winter.

A new genetic analysis using data from over five million people has provided a clearer understanding of the risk of going on to live with obesity.  New research led by the Universities of Copenhagen and Bristol shows analysing genes at a young age may support early strategies to prevent obesity developing later in life. The World Obesity Federation expects more than half the global population to become overweight or obese by 2035. However, treatment strategies such as lifestyle change, surgery and medications are not universally available or effective. By drawing on genetic data from over five million people, ...

As far back as the 4th Century B.C., Aristotle marveled at the nimble gecko's ability to “run up and down a tree in any way, even with the head downwards.”  Its grippy toes, able to latch on to even the slipperiest surface with extraordinary force, have inspired everything from super glues to “Superman” climbing suits to sponges for soaking up environmental toxins. Now CU Boulder scientists have taken a cue from the reptile to develop a material able to stick to tumors inside the body, pumping out chemotherapy drugs for days. The technology, developed ...

Tracking race-specific rates of cancer incidence and mortality is important for identifying racial differences in these outcomes and for monitoring efforts aimed at achieving the highest level of health for all. Researchers have assessed how well US race data collection standards and their revisions have captured cancer burdens for various racial groups over the years. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. Race data collection has followed recommendations from the US Office of ...

Immune responses rely on the efficient movement of immune cells within the complex and geometrically unpredictable three-dimensional tissues that make up our bodies. Recent research by the Sixt group at the Institute of Science and Technology Austria (ISTA) unveils how immune cells use their cytoskeleton to exert forces on their surrounding environment to push their way through tissues. The findings were published in Nature Immunology. “Eww; what, inside of me?” A common response when Patricia Reis-Rodrigues, a PhD student in the Sixt group at ISTA, reveals ...

ANN ARBOR, Mich. – Transitioning from diapers to the toilet is a major step for young children — and their parents. Now a new report shines a light on just how bumpy that journey can be. One in five parents say their child had potty anxiety during toilet training and another one in five say the process was harder than they expected, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health. “Learning to use the toilet is a major step in a young child’s development and requires time, patience, and consistency,” said Mott Poll Co-Director and Mott pediatrician Susan Woolford, M.D. “Our ...

Accurate removal of tumors is the most critical aspect of cancer surgery, yet it remains a significant challenge in clinical practice. In breast cancer, for example, the positive margin rate—where cancer cells remain at the surgical boundary—can reach up to 35%, often requiring reoperation and increasing the risk of recurrence. Preoperative imaging or ultrasound is often insufficient to fully identify tumor boundaries, forcing surgeons to rely heavily on experience. These limitations highlight the urgent need for technologies that can provide real-time tumor visualization during surgery. A joint research team led by ...

Owning a smartphone before age 13 is associated with poorer mind health and wellbeing in early adulthood, according to a global study of more than 100,000 young people. Published today in the peer-reviewed Journal of Human Development and Capabilities, the study found that 18- to 24-year-olds who had received their first smartphone at age 12 or younger were more likely to report suicidal thoughts, aggression, detachment from reality, poorer emotional regulation, and low self-worth. The data also shows ...

Beneath the scales of Australia’s iconic monitor lizards (commonly known as goannas), scientists have discovered an unexpected secret: a hidden layer of bony skin structures known as osteoderms. These structures, which have been long overlooked, may hold the key to understanding how these ancient reptiles not only survived but thrived in one of the world’s harshest environments.  The findings, published today in the prestigious Zoological Journal of the Linnean Society, mark the first large-scale global study of osteoderms in lizards and snakes. The international collaboration brought together researchers from Australia, Europe and the United States, who ...

Vaccination of pregnant women has been linked to a drop in newborns being admitted to hospital with a serious lung infection, research suggests. Researchers found the respiratory syncytial virus (RSV) vaccine, introduced across the UK in late summer 2024, led to a 72 per cent reduction in babies hospitalised with the virus if mothers were vaccinated. The findings are the first to show the real-world effectiveness of the vaccine in pregnant women in the UK. Uptake of the jab among pregnant women could help to limit the number of sick babies each winter, reducing hospital pressures, experts say. RSV is a common virus that causes coughs and colds but can lead to ...

JULY 2025 TIP SHEET Blood Cancer Expanding Donor Pool for Stem Cell Transplant Patients Blood cancer patients who have struggled to find a donor match for transplantation now have more options, according to new research from Sylvester. The study, published in the Journal of Clinical Oncology, showed that patients can achieve good outcomes with a partial match drawn from the national public donor registry when they are treated with the immune-suppressing drug cyclophosphamide. These findings should expand the donor pool for patients struggling to find a full match, said Antonio Jimenez Jimenez, M.D., physician-scientist and senior study author. Pap ...
