Noninvasive Raman device tracks blood glucose accurately in under a minute

MIT researchers developed a compact band-pass Raman spectroscopy device that noninvasively tracks glucose through the skin in under a minute using physically interpretable optical signals. In a pilot study and tissue phantom validation, the system showed glucose measurements comparable to commercial continuous glucose monitors, supporting further clinical evaluation.

Kiwifruit intake boosts vitamin C in skin and supports dermal structure

Study shows that increasing dietary vitamin C intake with kiwifruit raises vitamin C levels in both the dermis and epidermis through active transport from the bloodstream. Higher skin vitamin C levels were associated with increased skin density and epidermal cell proliferation, but not with improved UV protection or measurable increases in new collagen markers.

Calcium supplements do not prevent pre-eclampsia, large trials show no meaningful benefit

Despite long-standing recommendations, a major updated Cochrane review finds that calcium supplementation during pregnancy does not meaningfully reduce pre-eclampsia risk, prompting a rethink of how best to prevent hypertensive disorders in pregnancy.

Human researchers still outperform AI when it comes to writing trustworthy systematic reviews

Human researchers outperformed large language models across all major stages of systematic review preparation, particularly in study selection, synthesis, and final manuscript drafting. While LLMs demonstrated speed and partial accuracy in early screening and data extraction, they could not independently produce high-quality, guideline-compliant systematic reviews.

Walking speed before surgery predicts who thrives after hip replacement

This study shows that preoperative gait speed is a strong predictor of patient-reported pain relief, function, and joint awareness after total hip arthroplasty for osteoarthritis. A walking speed of at least 1.0 m/s before surgery independently predicts excellent postoperative outcomes.

Early exposure to fat-related food smells increases lifelong obesity risk

Early exposure to fat-related food odors during development alters central sensory processing and metabolic regulation, independently of maternal obesity or nutrient intake. These sensory cues program long-term susceptibility to obesity, impaired thermogenesis, and altered brain responses to dietary fat in adulthood.

Smartphone motor tests can predict dopamine deficiency in Parkinson’s disease without brain scans

Researchers explore the use of smartphones coupled with clinical scores to evaluate motor function and predict dopamine deficiency.

Study reveals how viral social interactions shape resistance to antivirals

Interactions among viruses can help them succeed inside their hosts or impart vulnerabilities that make them easier to treat. Scientists are learning the ways viruses mingle inside the cells they infect, as well as the consequences of their socializing.

Brainwide circuitry mapping reveals how psilocybin drives therapeutic neural rewiring

An international collaboration led by Cornell University researchers used a combination of psilocybin and the rabies virus to map how – and where – the psychedelic compound rewires the connections in the brain.

New Lancet series blends social science with medicine to tackle global health inequities

Can doctors in California learn from a patient who was bounced from one specialist to another in Japan? Can clinicians in London take lessons from a patient seeking asylum while suffering a medical emergency at the U.S.-Mexico border? Can doctors treating refugees in Africa inform health policy around the world?

CRISPR-based Cellgorithm technology ushers in a new era of cell programming

Syntax Bio, a synthetic biology company programming the next generation of cell therapies, today announced the publication of new research in Science Advances detailing the company's CRISPR-based Cellgorithm technology, which lays the groundwork for programmable control of gene activity in human stem cells and offers an alternative to the slow, variable manual processes researchers use today.

New atomic structure reveals how NBCn1 transporter protein aids breast cancer cell survival

UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps explain how these tumors resist environmental stress and thrive in acidic, low-oxygen environments that would normally be toxic to healthy cells.

Researchers highlight five pathways through which microplastics can harm the brain

Microplastics could be fueling neurodegenerative diseases like Alzheimer's and Parkinson's, with a new study highlighting five ways microplastics can trigger inflammation and damage in the brain.

Novel antibody suppresses primary tumor growth and spread of triple-negative breast cancer

Triple-negative breast cancer (TNBC) is one of the most aggressive and treatment-resistant forms of breast cancer. It grows quickly, spreads early and lacks the hormone receptors that make other breast cancers treatable with targeted therapies.

Smoking fewer cigarettes does not eliminate cardiovascular disease risk

In a study funded by the National Heart, Lung, and Blood Institute, new research from Johns Hopkins Medicine adds to existing evidence that smoking fewer cigarettes does not eliminate cardiovascular disease risk, and quitting entirely is the most effective strategy for improving health.

Study shows how respiratory rhythm shapes memory processes

First and foremost, we breathe in order to absorb oxygen - but this vital rhythm could also have other functions. Over the past few years, a range of studies have shown that respiration influences neural processes, including the processing of stimuli and memory processes.
