Fresh insights into how immune cells are regulated could signal a new approach to tackling infections.

A tiny, transparent device that can fit into a contact lens has a bright future, potentially helping a range of scientific endeavors from biomedicine to geology.

People with hemophilia require regular infusions of clotting factor to prevent them from experiencing uncontrolled bleeding. But a significant fraction develop antibodies against the clotting factor, essentially experiencing an allergic reaction to the very treatment that can prolong their lives.

Research from York University’s Lassonde School of Engineering, has found a new set of algorithms that can help determine the 3D structure of proteins to one day find new treatments for a range of diseases including Alzheimer’s, HIV and cancer. The research, published in the current edition of the journal Nature Methods, shows that these new algorithms rapidly generate 3-D structures of viruses, which could revolutionize the development of new drug therapies.

Pregnancy in the UK has never been safer, say scientists from King's College London writing in the latest edition of The Lancet.

The biological formation of neurotoxic methyl mercury is an enigmatic process underpinning mercury-related health and environmental hazards. Nevertheless, the exact mechanisms and the factors controlling the process are still not well understood.

In a collaborative effort, researchers at Uppsala and Umeå University now show that the formation of methylmercury in sediment is controlled by the molecular composition of the organic matter. The study has been published in Nature Communications.

A brown cloud of air pollution now frequently shrouds much of northern India. It’s a growing regional health and environmental problem, and scientists are working to understand its many causes, which range from the burning of agricultural waste to auto emissions.

We’ve all known for a long time that eating fast food is bad for you. It’s greasy, fatty, high in sodium and the calorie count is obscene. Now comes news that even the packaging that food comes in might be dangerous to your health.

A new study found dangerous chemical compounds in almost half of the 400 fast food containers it tested from 27 fast food franchises. Packaging tested in this study came from the Big Four: McDonald’s, Chipotle Mexican Grill, Starbucks and Yum! Brands, Inc., which operates Taco Bell, KFC, Pizza Hut and WingStreet.

The substances in question are perfluorinated chemicals (PFCs). That’s the same stuff that once was used to make Dupont’s Teflon before it had to be removed from the market. It’s also used in carpeting, furniture, clothing and cosmetics because of its water-repellant and stain-resistant qualities. We’re exposed to it every day.

A major report led by Vanderbilt investigators found that the mere presence of even a small amount of calcified coronary plaque, more commonly referred to as coronary artery calcium (CAC), in people under age 50 — even small amounts — was strongly associated with increased risk of developing clinical coronary heart disease over the ensuing decade.

A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks acquire immunity that limits the size of subsequent epidemics.

The study, published February 8 in Proceedings of the Royal Society B, involved researchers from UC Santa Cruz, Stanford University, and the New York State Department of Health. They analyzed 15 years of data on human West Nile virus infections from across the United States and found that epidemics were much larger in drought years and in regions that had not suffered large epidemics in the past.
