In the three-and-a-half years since the U.S. Supreme Court overturned the constitutional right to an abortion in Dobbs v. Jackson Women’s Health Organization, the fragmented state of abortion access has put medical professionals in a precarious position. Many states have tightened abortion restrictions, with some enacting criminal penalties up to life in prison for physicians who perform abortions. Medical schools have curtailed abortion-related curricula. New research led in part by the University of Washington found that the new restrictions are not only affecting the current medical workforce — they may ...

URBANA, Ill. – Fried foods are popular with consumers, but their high fat content can contribute to health challenges like obesity and hypertension. If the food industry can offer lower-fat options of similar quality, people can more easily make health-conscious food choices. Researchers at the University of Illinois Urbana-Champaign have explored microwave frying of French fries, providing insights that can help food manufacturers modify their production methods. They propose combining conventional frying with microwave frying to provide the desired crispiness and texture while reducing the cooking time and oil absorption. “Consumers ...

When a cocaine addict relapses, it isn’t a matter of personal failure — it’s the biological result of their brain’s rewiring, new research finds. Michigan State University scientists found that cocaine changes how the hippocampus functions, contributing to the ongoing compulsion to seek out the drug. Their National Institutes of Health-supported research, published in Science Advances, not only explains why cocaine addiction is notoriously difficult to treat, but it could also help scientists develop new pharmaceutical therapies. “Addiction is a disease ...

Mosquitoes transmit several pathogens of public health importance, including malaria, dengue, chikungunya and ZIKA. These vector-borne diseases are responsible for millions of cases every year, and hundreds of thousands of deaths. The most effective way to cope with the threat of emerging or re-emerging vector borne diseases is the prevention by rigorous surveillance system, which can help early detection of risk and the initiation of mitigation efforts (e.g. mosquito control). In recent years, numerous technologies have been developed to monitor and control vectors and vector-borne diseases, many of which rely ...

UCLA scientists have developed a next-generation CAR-T cell therapy that can overcome the immunosuppressive tumor microenvironment, a protective shield that tumors use to weaken immune cells, block their attack and fuel tumor growth.  By equipping CAR-T cells with the ability to block a key tumor-produced protein called VEGF, the researchers gave the engineered immune cells the power not only to attack cancer directly, but also to dismantle the tumor’s defenses and restore the immune system’s ability to fight back.  In preclinical ...

Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as well as the onset of a period of unusual stability in Earth's magnetic field, known as the Cretaceous Normal Superchron (CNS), which lasted about 38 million years. The prevailing hypothesis has been that rapid, volcanism-driven atmospheric CO₂ emissions triggered an immediate and globally synchronous carbon-cycle perturbation across both land and ocean systems, particularly marked by the onset of OAE1a. Proving this hypothesis has been challenging, ...

New 3D reconstructions of a key sensory organ in ctenophores reveal an unexpected structural and functional complexity. The findings suggest that an elementary brain may have already appeared in our most ancient relatives, reshaping our understanding of nervous system evolution in animals. Ctenophores – or comb jellies– are gelatinous animals that appeared in the ocean an estimated 550 million years ago. The delicate animals possess a specialized sensory structure called the aboral organ (AO), which allows them ...

HOUSTON (March 4, 2026) – A team of researchers at Texas Children’s Duncan Neurological Research Institute (NRI) and Baylor College of Medicine report in Science Translational Medicine a potential new approach to treat Rett syndrome – offering early promise for a rare neurodevelopmental disorder that currently has no cure. “Rett syndrome is a rare genetic neurodevelopmental condition that causes a regression in development, typically after 6 to 18 months of normal growth, leading to severe impairments in motor skills, speech and communication,” said corresponding ...

Expertise isn’t easy to pass down. Take riding a bike: A seasoned cyclist might talk a beginner through the basics of how to sit and when to push off. But other skills, like how hard to pedal to keep balanced, are more intuitive and harder to articulate. This implicit know-how is known as tacit knowledge, and very often, it can only be learned with experience and time.  But a team of MIT engineers wondered: Could an expert’s unconscious know-how be accessed, and even taught, to quickly bring a novice up to an expert’s level?  The answer appears to be “yes,” at least for a particular type of visual-learning task.  In a study published ...

Just a few days in simulated microgravity can subtly change the way women’s blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser University researchers.  First reported in 2020, an International Space Station mission detected an unexpected blood clot in a female astronaut’s jugular vein. To date, space-health research has had more male participants but with the number of female astronauts on the rise, a new SFU–European Space Agency study examined how microgravity affects blood clotting specifically ...

Irvine, Calif., March 4, 2026 — Cataracts are a leading cause of blindness worldwide and are considered a priority disease by the World Health Organization. In a new study, researchers at the University of California, Irvine uncovered how a subtle chemical change in an eye lens protein can make the protein more likely to clump together over time, suggesting an early step in cataract formation. The research, published in Biophysical Reports, focuses on proteins called crystallins, which help keep the eye lens clear. These proteins are meant to last a lifetime. But unlike most cells in the body, the lens cannot replace damaged proteins, so chemical changes can gradually accumulate ...

All-solid-state batteries (ASSB) are widely recognized as a safer and potentially more energy-dense alternative to conventional lithium-ion technologies. Their performance critically depends on fast ionic conduction within solid electrolytes. Traditional methods to identify such materials involve labour-intensive synthesis and characterization processes, often hampered by the limitations of existing computational models in accurately capturing disordered, high-temperature ionic behaviours. The detection and prediction of liquid-like ion motion in crystalline materials has remained a major challenge, particularly because conventional computational ...

Philadelphia, March 4, 2026 – The use of generative artificial intelligence (AI), able to produce text, images and video on demand, has grown exponentially in recent years. While its applications for personal and professional use continue to expand, many have questions about how children might be interacting with this technology. In a new state of the review article, researchers from Children’s Hospital of Philadelphia (CHOP) describe the potential benefits and risks to children and adolescents and how these might vary over different age groups. Their findings were published today ...

Nijmegen, 27 February 2026 - Think about the last time you told a story to a friend. You probably adjusted it halfway through. You saw their eyebrows lift. You noticed them lean in, or glance away. You clarified a detail. You sped up the ending. That constant fine-tuning is not a bonus feature of communication: it ís communication. And you can read all about this real-time coordination process in a new review by Judith Holler and Anna K. Kuhlen (Max Planck Institute for Psycholinguistics), published in Nature Reviews Psychology. Holler ...

The DNA foundation model Evo 2, first released in February 2025 as a preprint, is now published in the journal Nature. Trained on the DNA of over 100,000 species across the entire tree of life, Evo 2 can identify patterns in gene sequences across disparate organisms that experimental researchers would need years to uncover. The machine learning model can accurately identify disease-causing mutations in human genes and is capable of designing new genomes that are as long as the genomes of simple bacteria. Evo 2 was developed by scientists from Arc Institute and NVIDIA, convening collaborators across Stanford University, UC Berkeley, ...

Cambridge scientists have shown that when tumours first emerge, interactions with healthy cells in the underlying supportive tissue determine their ability to survive, grow, and progress to advanced stages of disease. The study, carried out in mice and further validated using human tissue, may explain why some tiny, newly-formed tumours disappear, while others manage to survive and eventually grow into cancer. Tumours arise when our DNA accumulates errors, or mutations, causing the cells to grow faster and ignore signals that would otherwise instruct ...
