These tiny soil microbes could rescue crops from salty farmland

9:38
Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilient. Greenhouse and field tests showed healthier plants and higher yields in salty conditions. The findings could lead t…

Brain activity under anesthesia challenges what we know about consciousness

9:38
The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more remarkably, neural activity showed signs of predicting upcoming words before they were heard. The results challenge tradi…

Millions take omega-3 fish oil for brain health but a new study found no benefit

9:38
Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer’s-related brain changes. The results challenge the idea that fish oil pills can help prevent Alzheimer’s and shift attention toward overall diet and lifestyle instead.

James Webb uncovers exotic salt clouds on a mysterious pink world

28.června
Astronomers have finally cracked the mystery of the famous “Pink Planet,” a strange world 57 light-years away that has puzzled scientists for more than a decade. Using the James Webb Space Telescope, researchers discovered that its atmosphere contains water vapor, methane, carbon dioxide, ammonia, and something never directly confirmed before in such an object: salty clouds.

Only one workout helped older adults lose fat without losing muscle

28.června
A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise: it helped reduce body fat while preserving valuable muscle mass. While moderate and low-intensity workouts also led to some fat loss, only HIIT maintained lean muscle, which becomes increasingly important with age.

Common pesticide linked to more than double the risk of Parkinson’s disease

28.června
Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson’s disease. People exposed to the chemical near their homes were more than twice as likely to develop the condition. Laboratory studies showed that chlorpyrifos damages dopamine neurons and interferes with the brain’s ability to remove toxic protein buildup.

Hawaii is turning ocean plastic and fishing nets into roads

28.června
Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads. Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material. If future studies confirm the roads are durable, the technology could help tackle both marine pollution and overflo…

New vitamin B12 therapy shows promise against deadly brain cancer

28.června
Researchers have identified a vitamin B12–based compound that can cross the blood-brain barrier and home in on glioblastoma tumors. In animal studies, the compound accumulated preferentially in tumor tissue and delivered sustained nitric oxide directly to cancer cells. It also worked synergistically with existing glioblastoma treatments, significantly enhancing their tumor-fighting effects.

Massive study links teen marijuana use to double the risk of serious mental illness

28.června
Teens who use cannabis may face a substantially greater risk of developing serious mental health conditions, including psychotic and bipolar disorders, according to a study of more than 463,000 adolescents. Researchers found cannabis use often preceded these diagnoses by nearly two years, strengthening concerns about its long-term effects on developing brains.

Yellowstone’s supervolcano may be fueled by something unexpected

28.června
Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath Yellowstone, generating magma closer to the surface. This process helps create a massive underground magma network and may explain how supervolcanoes remain active for long periods.

Astronomers found two rare super puff planets lighter than cotton candy

27.června
Two newly confirmed "super-puff" planets are so diffuse that they are less dense than cotton candy, despite being about the size of Jupiter. Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how some of the strangest planets in the galaxy come to exist.

Scientists discover what triggers belly fat as we age

27.června
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.

Einstein Probe may have caught a black hole tearing apart a white dwarf for the first time

26.června
Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in its earliest moments, revealing an unusual sequence of intense X-ray flashes unlike anything seen in a typical gamma-ray burst.

Earth may have been seeding Venus with life for billions of years

26.června
A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—it may have come from Earth.

Researchers discover why fructose doesn't satisfy hunger like glucose

26.června
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. The findings suggest that the type of sugar—not just the calories…
