Common plastic chemical linked to lifelong anxiety in new study

13:36
Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed significantly higher anxiety as adults, even long after exposure had ended. The animals were more hesitant to explore open spaces and spent more time froz…

Superconductivity breakthrough could unlock ultra-efficient electronics

11:18
A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields.

A daily probiotic may help relieve depression and anxiety

11:18
A small clinical trial suggests that probiotics may offer a surprising mental health boost for older adults with depression. Seniors who took a daily probiotic alongside their regular antidepressant treatment experienced slightly greater improvements in depression and anxiety symptoms than those who received a placebo.

New plasma trick could unlock smaller, more powerful computer chips

11:18
A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials. Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma processing. The result is a cleaner, more controlled path toward smaller and more capable electronics.

New procedure delivers lasting knee arthritis pain relief without surgery

11:18
A minimally invasive treatment that blocks inflammation-driving blood vessels in the knee provided significant pain relief and improved function for osteoarthritis patients, with benefits lasting at least a year. The procedure was safe, highly successful, and could offer a new alternative for people seeking relief before considering knee replacement.

Scientists say most of what’s in your food is still a mystery

11:18
Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels. This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why different diets affect people in dramatically different ways.

10 surprising ways diabetes and dementia are connected

4:03
Diabetes and dementia appear to be closely intertwined, with each condition potentially influencing the other. Problems with insulin and glucose can affect the brain’s energy supply, increase inflammation, and damage blood vessels linked to memory loss. Researchers are also finding that some popular diabetes medications may lower dementia risk. These discoveries are opening new possibilities for …

Scientists found an early depression clue hidden in children’s eyes

4:03
Depression appears to change what children notice in the faces around them, but the effect depends on family history. Kids with a higher inherited risk became more focused on sadness, while lower-risk children lost some of their natural attention to happy expressions.

Alien messages may have reached Earth without us realizing it

18:24
A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to spot. The effect could be especially important ar…

Scientists just found a hidden weakness in forever chemicals

18:24
Researchers discovered that hydrogen radicals generated by intense UV light can break down stubborn PFAS “forever chemicals” without added chemicals. The breakthrough reveals a key mechanism that could lead to greener and more effective technologies for permanently destroying these pollutants.

Scientists found a way to explain bird flocks that “defy” Newton’s third law

18:24
Physicists have solved a long-standing problem involving systems that appear to violate Newton’s third law, such as bird flocks and bacterial swarms. By adding carefully designed “imaginary partners” to their models, they can now simulate these complex systems with unprecedented accuracy.

New study explores potential cross-species spread of chronic wasting disease

18:24
A new study found that chronic wasting disease can sometimes spread silently, with infectious prions present even in animals that show no symptoms. While there is no confirmed human risk, researchers say the disease’s ability to evolve and spread across species warrants close attention.

Most people who stop GLP-1 drugs like Ozempic eventually return

18:24
Many people prescribed GLP-1 drugs for type 2 diabetes (such as Victoza, Ozempic, or tirzepatide) stop taking them, but a surprising number later return to treatment. Researchers found that newer medications appear to keep patients on therapy longer, while side effects remain a major reason for discontinuation.

Semaglutide (Ozempic) linked to fewer bone fractures despite greater weight loss

18:24
A large real-world study suggests semaglutide (Ozempic, Wegovy, Rybelsus) may offer an unexpected bonus for people with type 2 diabetes: stronger protection against bone fractures while delivering greater weight loss. Researchers analyzing health records from nearly 60,000 adults found that people taking semaglutide experienced about 15% fewer fractures than those using other common weight-loss m…

Copper drug clears toxic Alzheimer’s proteins and restores memory

18:24
A copper-based compound restored the brain’s ability to clear toxic Alzheimer’s proteins, dramatically reducing amyloid buildup and improving memory in laboratory experiments. The findings point to a potentially fast-tracked new treatment strategy because the drug has already been tested in humans for other neurological conditions.
