A drug for extreme hunger offers clues to obesity's complexity

One of the nation's largest food companies is planning a big change to its ingredients list.

Brain death determination sits at the fraught intersection of critical-care medicine, ethics, and organ-donation logistics. Missteps risk either prolonging mechanical support with no prospect of recovery or declaring death in error—a prospect that evokes the terrors of many Edgar Allan Poe writings.

There are over 15 million people living with spinal cord injury (SCI) worldwide. Experimental treatments using electrical stimulation through the skin may help some patients regain movement, but researchers still have a lot to learn.

Up to 1 in 3 adults and young people with epilepsy also have mental health conditions such as depression and anxiety. A new set of recommendations aims to help neurologists offer a more integrated approach to care.

Researchers from the University of California San Diego and UC San Francisco have found that Proposition 56, a major tobacco tax increase that was overwhelmingly approved by California voters in 2016, was associated with a significant increase in smoking cessation over the next three years. The study, published in the Journal of the National Cancer Institute, also reported significant differences in state tobacco spending and the proportion of people smoking daily.

The liver is one of the hardest working organs in the human body. It detoxifies harmful substances, helps with digestion, stores nutrients, and regulates metabolism.

As the weather warms up, few of us can resist a nice evening walk through the park, or a trip to the countryside to immerse ourselves in natural surroundings.

Many experts believe that social isolation is a risk factor for Alzheimer's disease. But a new study, led by UC San Francisco and Boston University, examined the social habits and genetic data of half a million Britons whose average age was 56, and found that the disease may make them more sociable rather than less—at least in the early stages.

Proteoglycans are large molecules that are important for tissues all over the body. For example, they play key roles in the development of cartilage and blood vessels, and they can also protect against inflammation and infection. But their role in cancer is less clear: while some proteoglycans protect against cancer, others can promote tumor growth.

Living in a U.S. coastal county bordered by ocean waters with very high concentrations of microplastics may increase the risk of heart and metabolic diseases, such as type 2 diabetes, coronary artery disease and stroke.

Gene expression, where cells use the genetic information encoded in DNA to produce proteins, has been thought of as a dimmer light.

Runny nose, itching eyes, worsening asthma symptoms—the effects of hay fever are nothing to sneeze at, experts say, warning of an "explosion" of allergies as climate change lengthens and intensifies pollen seasons.
