A robotic arm that moves too quickly can feel creepy. One that moves too slowly feels awkward and unhelpful. In a VR study, researchers found that AI-powered prosthetic arms were best accepted when they moved at a natural, human-like speed—about one second…

A protein called HIF1 may be the missing link behind painful tendon injuries like jumper’s knee and tennis elbow. Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, turning…

Microplastics and nanoplastics are now found everywhere on Earth, from ocean depths to agricultural soils and even inside the human body. Yet scientists still struggle to understand what these particles actually do once they enter living organisms. A new…

A low-fat vegan diet—without cutting calories or carbs—may help people with type 1 diabetes significantly reduce how much insulin they need, and how much they spend on it. In a new analysis published in BMC Nutrition, participants following the plant-based…

Despite longstanding guidelines, many dementia patients are still prescribed brain-altering medications that can raise the risk of falls and confusion. A new study shows that while prescribing has decreased overall, people with cognitive impairment remain…

If you've ever read a food label and come away feeling more confused, you're not alone. Since 2014, Australian shoppers have relied on the Health Star Rating scheme to help them choose which foods to ...

A new study reveals that alpha brain waves help the brain decide what belongs to your body. Faster rhythms allow the brain to match sight and touch more precisely, strengthening the feeling that a body part is truly yours. Slower rhythms blur that timing…

A damaging cotton virus thought to be a recent invader has actually been hiding in U.S. fields for nearly two decades. New research shows cotton leafroll dwarf virus was present as early as 2006, quietly spreading across major cotton-growing states long before…

Fish oil’s cancer-fighting reputation may hinge on a little-known gene. Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially…

Psychedelic substances are increasingly being used under medical supervision to treat anxiety disorders and depression. However, the mechanisms by which these substances influence our perception and consciousness ...

Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from…

A massive international brain study has revealed that memory decline with age isn’t driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time. Analyzing thousands of MRI scans and memory tests from…

Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine darkwaves”…

Although humans' visual perception of the world appears complete, our eyes contain a visual blind spot where the optic nerve connects to the retina. Scientists are still uncertain whether the brain fully ...

Cell and gene therapies, or CGT, have come a long way since they were first introduced. In the last few decades, both cell therapy—the transplantation of living cells—and gene therapy—the use of ...

King's College London researchers have created a unique collection of human stem cell models that could help to uncover why HIV leads to different outcomes in different people. The research was carried ...

Acupuncture may be an effective treatment for migraine without aura, a type of migraine that occurs without warning signs like flickering lights. A new study published in the journal JAMA Network Open ...

A new discovery may explain why so many people abandon cholesterol-lowering statins because of muscle pain and weakness. Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells.…

Scientists are taking a closer look at monk fruit and discovering it’s more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive compounds that may support health. Different varieties offer different…

Scientists have traditionally studied how the brain controls movement by asking patients to perform structured tasks while connected to multiple sensors in a lab. While these studies have provided important ...

A positive newborn screening for spinal muscular atrophy (SMA) is currently considered a medical emergency. Without early treatment, severe disability or death in infancy are likely. However, research ...
