New light-based technique reveals the inner workings of cells14:03 Human cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers, including those from the University of Tokyo, used a light-based technique called Raman spectroscopy to create snapshots of the entire protein landscape inside an E. coli cell in a non… The simple link between core strength and brain health14:03 The brain is more mechanically connected to the body than previously appreciated, scientists reported today (April 27) in Nature Neuroscience. Through a study using mice and simulations, the team found a potential biological mechanism underlying why exercise is thought to benefit brain health: abdominal contractions compress blood vessels connected to the spinal cord and the brain, enabling the organ to gently move within the skull. Scientists uncover why brain damage continues after stroke14:03 Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered questions in neuroscience. A new biological switch to slow atherosclerosis progression14:03 A study by researchers at Baylor College of Medicine and collaborating institutions reveals a previously unrecognized way blood vessels can protect themselves from damage and slow the development of atherosclerosis. The findings, published in the Proceedings of the National Academy of Sciences, have implications for both vascular precision medicine and the safety of certain emerging cancer treatm… FINGERS-7B to eradicate Alzheimer's symptoms14:03 Alzheimer's disease is best addressed as early as possible, ideally before symptoms become apparent. To enable early, accurate risk prediction both for individuals and whole populations, a team of AI researchers, physicians, and scientists centered at MIT has released FINGERS-7B, the first AI foundation model built to make Alzheimer's preventable. Modeling the synergy of maternal screening and newborn HBV vaccination13:30 Hepatitis B virus (HBV) infection acquired at birth or during early infancy can lead to lifelong health complications, including chronic liver disease. Despite longstanding recommendations for prenatal screening, an estimated 12% to 16% of pregnant individuals in the US are not screened for hepatitis B. This gap leaves a portion of newborns at risk for undetected exposure. New insights into predicting myeloma drug response13:30 Although patients with the same cancer diagnosis may respond very differently to treatment, clinicians still have limited tools at their disposal to predict who is most likely to benefit or suffer from a particular myeloma therapy. MIT’s optical paradox redefines high-resolution imaging12:57 Massachusetts Institute of Technology researchers discovered a paradoxical phenomenon in optical physics that could enable a new bioimaging method that's faster and higher-resolution than existing technology. Lipid pathways driving diabetes and heart disease risk in South Asians12:57 Identifying lipid-linked genetic pathways in Asian Indians offers insights into diabetes and heart disease, crucial for developing ancestry-specific therapies. Ultra-processed foods linked to poorer attention and higher dementia risk scores12:26 Research shows that higher ultra-processed food consumption may impair attention and elevate modifiable dementia risk, highlighting concerns for brain health. |
