Mutations disrupt touch-based learning, study finds
2025-03-13
You may scarcely notice it, but much of what you do every day requires your brain to engage in perceptual learning. To safely cross an intersection or quickly retrieve something from your bag, you depend upon your brain to first assign meaning to sensory input from your eyes or fingertips.
Usually, it’s effortless.
Research from The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology shows a gene called Syngap1 enables touch-based perception, while certain mutations can lead to mixed signals. The research was made possible through grants from the National Institute of Mental Health and the National Institute ...

NIH’s flat 15% funding policy is misguided and damaging
2025-03-13
The U.S. National Institutes of Health’s recent decision to impose a 15% cap on facilities and administrative (F&A) cost reimbursements threatens to undermine the quality and sustainability of university research by slashing indirect funding by $4 billion. In a Policy Forum, Jeongwon Choi and colleagues argue that this policy is fundamentally flawed, as it disregards the essential role of indirect costs, such as infrastructure, utilities, and administrative support, in enabling scientific research. The current system, governed by rigorous federal oversight and audits, ensures that F&A reimbursements are fair and necessary, varying across institutions based on actual costs. NIH’s ...
AI reveals new insights into the flow of Antarctic ice
2025-03-13
As the planet warms, Antarctica’s ice sheet is melting and contributing to sea-level rise around the globe. Antarctica holds enough frozen water to raise global sea levels by 190 feet, so precisely predicting how it will move and melt now and in the future is vital for protecting coastal areas. But most climate models struggle to accurately simulate the movement of Antarctic ice due to sparse data and the complexity of interactions between the ocean, atmosphere, and frozen surface.
In a paper published March 13 in Science, researchers at Stanford University used machine learning to analyze high-resolution ...

Astronomy’s dirty window to space
2025-03-13
When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it appears? Or does the star merely look reddish, since its light has had to travel through a cloud of cosmic dust to reach our telescope? For accurate observations, astronomers need to know the amount of dust between them and their distant targets. Not only does dust make objects appear reddish (“reddening”), it also makes them appear fainter than they really are (“extinction”). It’s like we are looking out into space through a dirty ...

Combination immunotherapy before surgery may increase survival in people with head and neck cancer
2025-03-13
CHAPEL HILL, North Carolina—Researchers conducting a clinical trial of immunotherapy drugs for people with head and neck squamous cell carcinomas (HNSCCs) found that patients responded better to a combination of two immunotherapies than patients who received just one immunotherapy drug.
The scientists also analyzed immune cells in each person’s tumor after one month of immunotherapy to see which type of immune cells were activated to fight their cancer, suggesting that some of the cells and targets they identified could help individualize treatment benefit.
The findings appeared March 13, 2025 in Cancer Cell.
HNSCCs occur in the oral cavity, pharynx, hypopharynx, larynx, nasal ...
MIT engineers turn skin cells directly into neurons for cell therapy
2025-03-13
CAMBRIDGE, MA -- Converting one type of cell to another — for example, a skin cell to a neuron — can be done through a process that requires the skin cell to be induced into a “pluripotent” stem cell, then differentiated into a neuron. Researchers at MIT have now devised a simplified process that bypasses the stem cell stage, converting a skin cell directly into a neuron.
Working with mouse cells, the researchers developed a conversion method that is highly efficient and can produce more than 10 neurons from a single skin cell. If replicated in human ...

Checking PSA levels too soon after prostate cancer surgery can lead to overtreatment
2025-03-13
After surgical removal of the prostate to treat prostate cancer, clinicians monitor Prostate Specific Antigen (PSA) levels. Persistently elevated PSA levels indicate residual cancer and are linked to worse outcomes. But in a paper published in JAMA Oncology, Mass General Brigham researchers found that the current standard monitoring time of one-and-a-half to two months following surgery is too short to accurately identify recurrence and inform treatment decisions. Rather, PSA levels should be measured for at least three months to avoid overtreatment.
“Checking ...
