Our Sun may have escaped the Milky Way’s center with thousands of twin stars
Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of Sun-like stars billions of years ago. The journey may have carried the solar system away from the galaxy’s crowded center into a calmer region where life could eventually emerge.
Scientists warn Australia’s “zombie tree” could vanish within a generation
A newly identified Australian tree has been dubbed the “zombie” tree because it’s alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow disease-free seedlings in protected locations. Their hope is that a future generation may evolve resistance and bring the species back from the brink.
Monty Python Got It Wrong About Medieval Disease
In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases like leprosy were buried in these high-status spots. Instead of excluding the sick, many communities appear to have treated them much like everyone else.
Gut bacteria that make serotonin may hold the key to IBS
Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal movement. The study also found that people with IBS have lower levels of one of these bacteria. The discovery suggests gut microbes could become a powerful new target for treating digestive disorders.
Microplastics may be quietly damaging your brain and fueling Alzheimer’s and Parkinson’s
Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Scientists estimate adults may consume about 250 grams of these particles each year, and some can accumulate in organs including the brain.
Scientists crack a 20-year nuclear mystery behind the creation of gold
Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to understand the nuclear steps that create them. Now, nuclear physicists have uncovered three key discoveries about how unstable atomic nuclei decay during the rapid neutron-capture process, the chain reaction responsible for forging elements like gold and platinum.
Simple water trick cuts diesel engine pollution by over 60%
Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions that improve fuel mixing and lower combustion temperatures. Studies show this technique can slash nitrogen oxide and soot emissions by more than 60% while sometimes even improving engine efficiency. Because it works in existing engines without redesign, it could provide a quick path to cleaner diesel
The surprising new ways bacteria spread without propellers
Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and creating tiny fluid currents that carry them forward — a newly identified behavior researchers call “swashing.” In another study, a different group of bacteria was shown to control its movement using a microscopic molecular “gearbox” that can
Scientists discovered a secret deal between a plant and beetles
A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of those fruits, yet the larvae survive by escaping into the soil. The discovery suggests that fruit drop is not punishment but a compromise that keeps the plant–insect relationship stable.
Depression may start with an energy problem in brain cells
Researchers have discovered a surprising change in how cells produce energy in people with depression. Brain and blood cells in young adults with major depressive disorder produced more energy molecules at rest but had trouble increasing energy production when needed. Scientists believe this imbalance may contribute to symptoms such as fatigue and low motivation. The finding could help pave the way for earlier diagnosis and more personalized treatments.
A surprising blood protein pattern may reveal Alzheimer’s
A new study suggests Alzheimer’s disease may be detectable through subtle shape changes in proteins found in the blood. Researchers discovered that structural differences in three blood proteins closely track the progression of the disease. By analyzing these changes in more than 500 people, the team was able to distinguish healthy individuals from those with mild cognitive impairment or Alzheimer’s with impressive accuracy. The approach could help move diagnosis and treatment to earlier stages.
Chickpeas could become the first food grown on the Moon
Scientists have grown chickpeas in simulated moon soil, offering a promising step toward farming on the lunar surface. Researchers mixed moon-like regolith with worm-produced compost and helpful fungi that protect plants from toxic metals. The combination allowed chickpeas to grow and produce a harvest in soil that normally cannot support plant life. Scientists now need to confirm the crops are safe and nutritious for astronauts.
