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.

A new animal study has shown sugar contributes to metabolic diseases by altering the microbiome. The findings reveal how certain gut bacteria protect against the harmful effects of a high-fat diet, and how sugar disrupts those protective mechanisms.

Transmitting data from medical implants in the body can be tricky, but a new technique can essentially write data to ions in human tissue, where it can then be read from a receiver outside the body at high transmission speeds.

Scientists exploring a novel but highly promising avenue of cancer treatment have developed a type of "invisibility cloak" that helps engineered bacteria sneak through the body's immune defenses, with potent anti-tumor effects.

Even though it's now possible to 3D-print foods into millimeter-precise shapes and forms, cooking those printed foods is still an inexact process. Scientists are trying to change that, by using lasers to cook foods to specific optimized standards.

Scientists at Columbia University believe they have uncovered an answer to why some cancer cells can evade immune system attacks, discovering a type of "blast shield " made of fat that can be weakened with specific compounds.

A new study has produced first-of-a-kind scientific evidence of the connection between stress and graying hair, identifying proteins that seem to drive this process while also demonstrating how it might even be reversed.

If you smiled at someone and they didn't smile back, you'd probably find it off-putting. Well, that's what usually happens if you smile at a humanoid robot … but not in the case of the expression-mirroring EVA.

Results from a trial testing an ultrasound therapy for hypertension show the treatment can deliver meaningful reductions in blood pressure. The treatment is based on a hypothesis that disrupting signals from renal nerves can reduce blood pressure.
