A new study has pinpointed how the APOE4 gene variant sabotages the brain’s energy balance, blocking neurons from burning fat for fuel when glucose runs low, a discovery that could reveal new ways to prevent or slow Alzheimer’s disease.

Not all concussions are created equal. A new study has revealed nine early warning signs that a mild head injury might linger longer than expected, and why spotting them within hours could change recovery outcomes.

For decades, scientists have suspected that the voices heard by people with schizophrenia might be their own inner speech gone awry. Now, researchers have found brainwave evidence showing exactly how this self-monitoring glitch occurs.

A humble kitchen spice could pack a powerful antiviral punch. Researchers have found that compounds in cardamom seeds can trigger the body’s virus-detecting systems, potentially paving the way for natural cold and flu treatments.

Pickleball’s boom has brought an unexpected side effect: a surge in serious eye injuries. A new study has revealed a sharp rise in pickleball-related eye trauma, promoting calls for protective eyewear standards.

After examining 13 million hours of light exposure data, researchers found that experiencing bright light during the dark hours can significantly increase the risk of heart failure and heart attack. The effect was most notable in younger adults.

For years, millions of people have sworn that gluten makes them ill – even if they've returned negative results when tested for coeliac disease. Now, researchers have found that it's far more complicated, and gluten itself may not be the culprit.

Stanford researchers and global collaborators have developed a wireless retinal implant called PRIMA that's helping people with untreatable eyesight loss see not just light, but actual shapes and patterns – what scientists call form vision.

Getting a COVID shot might do more than protect against the virus – it could also help cancer patients live longer. A new study found that mRNA vaccines were linked to a doubling in three-year survival for those on immunotherapy.

New research challenges fears about stopping long-term prescription opioid use, uncovering no associated rise in suicide risk and a sharp drop in overdose death. The findings offer reassurance for clinicians and patients managing chronic pain.

A 13-year-old boy was admitted to hospital after four days of abdominal pain – when he then admitted to doctors that he'd swallowed 80-100 small high-powered magnets. It's the latest in a trend that's more serious that what it may first appear to be.

In a world-first breakthrough, scientists have discovered how a sugary “cloak” helps bowel cancer hide from the immune system, and how stripping it away could turn the body’s anti-cancer defenses back on.

When choosing a protein powder, we want it to be low in sugar and carbs, and to taste good enough. We don't think that it might also be packed with dangerously high levels of lead – which, a new study finds, is exactly what is in many popular brands.

Training a service dog doesn’t just change the life of another veteran; it may help heal the trainer, too. A new study finds that volunteering with dogs could slow biological aging in female veterans with PTSD while easing stress and anxiety.

A novel treatment for irritable bowel syndrome (IBS) is on the horizon, with the discovery that two specific gut microbes produce serotonin that protects against inflammation and damage.
