The battle between butter and margarine comes down to chemistry. Butter's naturally occurring fats create rich flavors, golden browning, and flaky baked goods, while margarine's modified plant oils offer consistency and a longer shelf life. Although ...

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High ...

Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 ...

Researchers found that a rare liver cancer evades immunotherapy by luring immune T cells away from the tumor and trapping them in nearby fibrous tissue. An FDA-approved drug called AMD3100 freed those T cells to attack the cancer, significantly ...

How does a single cell build a brain with billions of precisely organized neurons? Researchers suggest that brain cells use their lineage--their cellular family tree--as a kind of positional map. Cells that come from the same ancestor stay near one . ...

Healthy older adults experienced measurable improvements in memory, physical performance, and stress after taking placebo pills for just three weeks. The most surprising finding was that the placebo often worked even when participants knew the pills ...

Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and ...

What if consciousness isn't limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on ...

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in . ...

Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny "footprints of death" packed with newly discovered particles that help guide the immune system to clean up the remains ...
