Improved 'molecular light switch' could restore sight, hearing and heart rhythm

When you're sick you'll often produce more phlegm, and might notice it's thicker or a different color: white, green, yellow or maybe even brown.

Solitary drinking has soared among young adults, climbing to rates not seen since the late 1970s.

An international study casts doubt on the widespread belief that higher levels of formal education directly protect against cognitive decline and brain aging. The study analyzed longitudinal data from more than 170,000 people in 33 western countries, making it one of the largest studies of cognitive aging to date.

You need fiber. That much is true. But in the world of online health trends, what started out as sound dietary advice has spiraled into "fibermaxxing"—a push to consume eye-watering amounts in the name of wellness.

Researchers at Edith Cowan University (ECU) have developed a cutting-edge Artificial Intelligence (AI) system that could support medical professionals in detecting and accurately diagnosing the stage of disease in a range of serious health conditions, including cardiovascular disease (CVD), diabetic eye complications, and cancer.

The targeted drug olutasidenib is highly effective in certain patients with myelodysplastic syndrome (MDS), a condition considered incurable without transplantation, according to a new clinical study led by researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

A research project led by the Ineos Oxford Institute for antimicrobial research (IOI) to study the cause and impact of antimicrobial-resistant sepsis in Nigeria has resulted in reduced newborn deaths, improved awareness about neonatal infection prevention among parents, and strengthened capacity and training for local doctors. The findings have been published in Nature Communications.

A groundbreaking new medical dataset is poised to revolutionize health care in Africa by improving chatbots' understanding of the continent's most pressing medical issues and increasing their awareness of accessible treatment options.

How much does your weight really say about your health? Probably less than you think. You could eat your five-a-day, hit the gym regularly, have textbook blood pressure and cholesterol levels—and still be dismissed as "unhealthy" based on the number on the scale. Meanwhile, someone with a so-called "healthy" weight might be skipping meals, running on stress and caffeine, and rarely moving their body.

In a first-of-its-kind study, researchers used a unique dataset to show that patients with type 2 diabetes have significantly worse financial outcomes than other patients.

Simple technology that harnesses ultraviolet light to zap airborne viruses has been shown to significantly lower the number of respiratory infections in aged care facilities, paving the way for smarter infection control.

Researchers at the University of Tokyo have explored how female body odor can influence behaviors in men. They found that certain scent compounds in female body odor increased during ovulation and can subtly influence how men feel.

A healthy diet can slow down the accumulation of chronic diseases in older adults, while inflammatory diets accelerate it. This is shown by a new study from Karolinska Institutet published in Nature Aging.

Green tea and red wine may seem like simple dietary choices—but beneath the surface, they harbor compounds with remarkable medical potential. Scientists are uncovering how these everyday drinks might support cancer treatment, not by replacing conventional therapies like chemotherapy or radiotherapy, but by enhancing their effectiveness and reducing their side-effects.

A Northeastern University researcher has identified a way to target two of the deadliest cancer types, melanoma and triple negative breast cancer, with chemotherapy drugs but without the harms associated with chemotherapy.

Harvard T.H. Chan School of Public Health suggests combining GLP-1 weight-loss medication with tailored nutrition and physical activity intervention is critical to mitigate side effects, preserve muscle, and prevent nutritional deficiencies.

An international research team has developed an easy online test capable of detecting toxoplasmosis infection without a blood sample, opening the door for a better understanding of how the common parasite affects human behavior.

Researchers at Nagoya University in Japan have developed a lipid nanoparticle that delivers mRNA to cells five times more effectively. By attaching a sulfur-containing ring structure—a cyclic disulfide—to lipid molecules, they found that significantly more mRNA can escape from cell components that normally destroy genetic material. When tested as a cancer vaccine in mice, the new delivery system stopped tumor growth.
