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 mice, the animals became unusually distractible—similar to what is seen in ADHD—but regained normal f
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。 But researchers found that influenza viruses can exploit this process, hiding inside these microsc
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 may also help keep cellular powerhouses called mitochondria functioning properly
A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones。 By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow the disease's relentless progression
Aging may trigger the appearance of specialized stem cells that supercharge the body's ability to create new belly fat。 The discovery reveals a potential biological driver of middle-age weight gain and a promising target for future anti-obesity treatments
Some brains appear to fight back against Alzheimer's by helping immature brain cells survive damage instead of succumbing to it。 Understanding this natural resilience could point researchers toward entirely new ways to protect memory and slow dementia
NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways。 The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth
Biology could explain the find, but there are other potential explanations
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-fructose corn syrup triggered a stronger response and was preferred by the animals
Scientists have solved a long-standing mystery by discovering the missing genetic ingredient that helps melanoma cells become effectively immortal。 The breakthrough could open the door to new treatments aimed at disrupting one of cancer's most important survival strategies
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 Earth。 Drawing on the vastness of the universe and the likely existence of countless alien civiliza
