Spatial attention enhances the processing of specific regions within a visual scene as people view their surroundings, much like a spotlight. Do people orient spatial attention the same way when processing mental images from memory? Anthony Clément and Catherine Tallon-Baudry, from École normale supérieure, explored whether neural mechanisms of spatial attention differ when discriminating between locations in mental images versus visuals on a screen.  In their JNeurosci paper, the researchers present an experimental task they developed that enabled them to record brain activity while human ...

A groundbreaking study published in Hypertension, the journal of the American Heart Association, has identified a set of blood-based biomarkers that can predict improvements in blood pressure five years after adolescents underwent metabolic bariatric surgery. This is the first study to demonstrate that measures of a patient’s unique biological profile taken before weight loss surgery can outperform traditional demographic and clinical risk factors in forecasting long-term blood pressure outcomes. “This is the first time blood-based biomarkers have been identified that predict which adolescents are most likely to experience improvements in blood pressure after bariatric ...

When ultra-runners lace up for races that stretch hundreds of miles and days, they’re not merely testing their mental grit and muscle strength—they’re probing the limits of human biology. Reporting in the Cell Press journal Current Biology on October 20, researchers found that even the most extreme athletes cannot surpass an average “metabolic ceiling” of 2.5 times their basal metabolic rate (BMR) in energy expenditure.  The metabolic ceiling represents the maximum number of calories a body can burn. Previous research suggested that people can burn up to 10 times their BMR, or the minimum energy required while at rest, for short bursts. ...

Depending on where you live in the United States, the meat you eat each year could be responsible for a level of greenhouse gas emissions that's similar to what's emitted to power your house. That's according to new research from the University of Michigan and the University of Minnesota published in the journal Nature Climate Change. The study provides a first-of-its kind, systematic analysis that digs into the environmental impacts of the sprawling supply chains that the country relies on for its beef, pork and chicken. Supported in part by the U.S. National Science Foundation, the team calculated and mapped those impacts, which they've dubbed meat's ...

Imagine you are a security guard in one of those casino heist movies where your ability to recognize an emerging crime will depend on whether you notice a subtle change on one of the many security monitors arrayed on your desk. That’s a challenge of visual working memory. According to a new study by neuroscientists in The Picower Institute for Learning and Memory at MIT, your ability to quickly spot the anomaly could depend on a theta-frequency brain wave (3–6 Hz) that scans through a region of the cortex that maps your field of view. The findings in animals, published Oct. 20 in Neuron, help to explain how the brain implements visual working memory and why performance ...

About one-third of patients with focal epilepsy, a common form of the neurological disorder, are believed to respond poorly to available therapies. Yet they too may eventually see improvement, if not total relief, from their seizures, a new study shows.  Most people with epilepsy have focal epilepsy, which occurs when nerve cells in a certain brain region send out a sudden, excessive burst of electrical signals. This uncontrolled activity, which is called a focal seizure, can cause problems such as abnormal emotions or feelings and unusual behaviors.  Led by NYU Langone Health researchers, the new study, which was part of the international ...

Scientists at University of California San Diego have developed a new approach to destroying cancer stem cells – hard-to-find cells that help cancers spread, come back after treatment and resist therapy. The new approach, which the researchers tested in colon cancer, leveraged artificial intelligence (AI) to identify treatments that can reprogram cancer stem cells, ultimately triggering them to self-destruct. Because it only targets cancer cells without affecting surrounding tissues, the approach could be a safer and more precise alternative to current therapeutic approaches. The results are published in Cell Reports Medicine. "Cancer stem ...

About The Study: This study characterized trends in the number of physicians participating in the Medicare program from 2013 to 2023 and identified physician- and county-level characteristics associated with program exit. Consistent with previous work, this study found a 6.3% increase in participating physicians, but physicians located in nonmetropolitan counties and full-shortage Health Professional Shortage Area counties were more likely to exit the program. The increased likelihood of Medicare program exits will likely reduce access to care for already underserved communities. Corresponding Author: To contact the corresponding author, Christopher ...

Ghent, 20 October 2025 – Researchers at VIB and Ghent University have uncovered a key mechanism that protects the skin from harmful inflammation. The findings, published in Immunity, could open new avenues for treating chronic skin diseases and other inflammatory disorders. Our skin is more than just a barrier; it is an active immune organ. When skin cells die in a controlled way, the body usually clears them without issues. But when too many cells die at once or in the wrong way, this process acts like an alarm signal that can trigger conditions such as psoriasis, lupus, or other inflammatory ...

Spinal cord injury (SCI) causes paralysis in roughly one million people worldwide, with incident cases rising yearly. Beyond motor and sensory deficits, patients frequently experience muscle atrophy, spasticity, heterotopic ossification, and autonomic dysfunction, all of which severely impair quality of life. Current treatments are rehabilitation-centered; medications, physical therapies, and surgery rarely reverse neural damage. In recent years, epidural electrical stimulation (EES) has emerged as a neurorehabilitation approach. Prior animal and clinical studies suggest that EES, delivered via electrodes implanted ...

CLEVELAND—Many eye banks won’t accept corneas from donors with diabetes, concerned they might be harder to prepare for transplant surgery or are more likely to fail. But a new study led by researchers at Case Western Reserve University and University Hospitals suggests otherwise. The results, published Oct. 17 in the journal JAMA Ophthalmology, found no significant differences in patients who received corneas from donors with diabetes than from those without the disease one year after the surgery. The implication is that the number of corneas available for transplant worldwide could be ...

PITTSBURGH, October 20, 2025 – A wireless retinal implant can restore central vision in patients with advanced age-related macular degeneration (AMD), according to clinical trial results published today in the New England Journal of Medicine. Advanced atrophic AMD, also known as geographic atrophy (GA), is the leading cause of irreversible blindness in older adults, affecting more than 5 million people worldwide.    The international, multi-center trial was co-led by José-Alain Sahel, M.D., director of the UPMC Vision ...

A tiny wireless chip implanted in the back of the eye and a pair of high-tech glasses have partially restored vision to people with an advanced form of age-related macular degeneration. In a clinical trial led by Stanford Medicine researchers and international collaborators, 27 out of 32 participants had regained the ability to read a year after receiving the device.  With digital enhancements enabled by the device, such as zoom and higher contrast, some participants could read with acuity equivalent to 20/42 vision. The results of the trial will be published Oct. 20 in the New England Journal of Medicine. The ...

After being treated with an electronic eye implant paired with augmented-reality glasses, people with sight loss have recovered reading vision, reports a trial involving a UCL (University College London) and Moorfields Eye Hospital clinical researcher. The results of the European clinical trial, published in The New England Journal of Medicine, showed 84% of participants were able to read letters, numbers and words using prosthetic vision through an eye that had previously lost its sight due to the untreatable ...

Age-related macular degeneration (AMD) causes progressive vision loss in many elderly people, and no treatment is available for the so-called atrophic form of the disease. A neurostimulation system called Prima, including a subretinal implant, could change all that. The results of a clinical trial involving Inserm, Sorbonne University and CNRS - via the Institut de la vision -, the Hôpital Fondation Adolphe de Rothschild and the Hôpital national des 15-20 show that it partially restored sight in over 80% of participants with AMD, who recovered their ability to read letters, numbers and words. The results are published in the New England journal of medicine. Age-related macular ...

Trains move through the world’s subway stations in a consistent pattern: arriving, stopping, and moving to the next stop—and repeated by other trains throughout the day. A new study by a team of New York University psychology and linguistics researchers finds that our brains work much the same way when processing several words at once—as we routinely do when listening to others speak. The work, which uncovers new ways the brain functions, appears in the journal Proceedings of the National Academy ...

The shrinking sea ice in the Arctic Ocean is, overall, a disaster. But paradoxically, the melting of the ice can also fuel the engine of the Arctic food chains: algae. Algae are the main food source for life in the sea, but they need nitrogen to grow. And nitrogen is in short supply in the Arctic Ocean. However, a new international study led by the University of Copenhagen indicates therewill probably be more of it in the future than previously thought. This could change the future prospects for marine life in the High North and possibly for the carbon budget. The researchers ...

Acute myeloid leukemia (AML), an aggressive and often fatal blood cancer, has long resisted a class of drugs called proteasome inhibitors, which work well in multiple myeloma. A new study by University of California San Diego researchers shows why: AML cells activate backup stress-response systems to stay alive when proteasomes are blocked. Proteasomes are cellular machines responsible for breaking down and recycling proteins, allowing cells to stay healthy. By combining proteasome inhibitors with a second drug that disables one of two backup survival pathways, the team was able to kill AML cells more effectively, reduce disease burden and extend ...
