A new study has found that people who exclusively use marijuana have higher levels of potentially dangerous metals in their blood and urine than those who don’t, suggesting the drug may be an overlooked source of metal exposure.

We all know fruit and vegetables are good for our overall health. But in a first-of-its-kind multi-year study, researchers have shown that flavanols found in these foods are tied to brain function, and a deficiency may drive age-related memory loss.

By removing certain amino acids from the diets fed to rodents suffering from glioblastoma, researchers found that brain cancer cells began dying. What's more, mice put on the restrictive diets were also more receptive to chemotherapy treatment.

We might soon replace our stovetops, ovens, and microwaves with 3D printers after mechanical engineers from Columbia University successfully created a cooked slice of cheesecake made from a record-breaking seven ingredients.

Cancer tumors are particularly adept at evading the body’s immune response, making treatment difficult. A new study has genetically engineered a common gut bacteria, enabling it to seek out and destroy cancer tumors from the inside.

In what sounds like sci-fi, transfusions of youthful blood can improve the health of older people. A new study has found that an existing arthritis drug can effectively rejuvenate blood stem cells, mimicking the benefits of young blood transfusions.

While bioengineered skin holds promise for people such as burn victims, the material has so far only been produced in flat sheets. Now, scientists have devised a method of growing it in 3D forms, which could be slipped onto the body like clothing.

In order for a soft-bodied robot to be practical, it has to be simple, light and energy-efficient, yet still reasonably quick. A newly developed mechanism fits the bill, and it's inspired by the humble hair clip.

Scientists at Columbia University are reporting an exciting advance in obesity treatment, demonstrating how positively-charged nanomaterials can be injected into unhealthy fat to return it to a healthy state.

It's assumed that as we get older our health will deteriorate. Our bodies age, wrinkles form, metabolism slows, and our immune system weakens. But how much of what we consider to simply be natural aging is actually due to preventable environmental factors?

Researchers have developed an implantable pump that can deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo the therapy while going about their day-to-day activities.

An incredible study has reported the discovery of a novel gut-brain pathway that drives our appetite for fatty foods. The research found cells in our gut sense the presence of fat in food and can directly talk to parts of our brain to make us keep eating.
