Interstellar comet may be oldest object seen in our solar system, research finds

Observations suggest comet spent billions of years on ‘vast unimaginable trajectories’ around our galaxyAn interstellar comet that blazed past the sun last year could be nearly three times older than our solar system and is unlike anything ever before seen in our cosmic back yard, astronomers said Monday.The comet 3I/Atlas is just the third visitor from beyond our solar system that humanity has ever observed, its unusual brightness offering scientists an unprecedented opportunity to study someth

NASA’s Webb Finds Clues to Ancient, Distant Origin of Comet 3I/ATLAS

As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted […]

More trees can mean fewer birds, new study reveals

Trees planted to protect farmland from wind may not be the biodiversity boost many assume. In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers found grassland bird abundance dropped by more than 70% near shelterbelts.

Future astronauts could walk across rocks from deep inside the Moon

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.

A common vitamin could help fight one of the deadliest brain cancers

A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected.

Butterfly that barely ages could help unlock longevity secrets

Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helping them stay healthy for longer.

Ebola and hantavirus can start like the flu but turn deadly fast

Two dangerous viruses are back in the spotlight, reminding health officials how quickly infectious diseases can become serious threats. Hantavirus, often linked to rodents, can cause severe heart and lung complications and has no specific treatment or vaccine, while certain strains can even spread between people. Ebola remains one of the world's most feared diseases, with some outbreaks killing up to half of those infected, although vaccines and antivirals have improved outcomes for some strains

T. rex took 40 years to reach full size, scientists find

Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years.

One common fat may fuel type 2 diabetes while another helps fight it

Not all fats affect your body the same way. Researchers found that palmitic acid, a saturated fat common in many foods, may contribute to insulin resistance and type 2 diabetes by triggering inflammation, toxic fat buildup, and cellular stress. In contrast, oleic acid—the heart-healthy fat abundant in olive oil—appears to help protect insulin function and may even counter some of the harmful effects of palmitic acid.

Chinese sodium battery surprised scientists by matching key Tesla benchmarks

Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries. If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative to lithium for EVs and large-scale energy storage.

As lakes turn brown, trout and bass decline while pike and walleye thrive

Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations. Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters. Meanwhile, walleye and northern pike often become more abundant because they are better adapted to low-visibility conditions. The shift could change both lake ecosystems and the fishing experience for millions of anglers.

Tubulin prevents toxic brain protein clumps linked to Alzheimer’s and Parkinson’s

Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the protein that builds the cell’s internal transport network—can redirect these proteins away from forming toxic clumps and toward healthy, productive work.

Yale study finds nearly half of older adults improved with age

A long-term Yale study is challenging one of the biggest myths about aging. Nearly half of adults over 65 improved physically, mentally, or both over time, despite the common belief that aging means constant decline. Researchers found that people with more positive attitudes about getting older were significantly more likely to show these gains.

Scientists discover neurons must break their DNA to build the brain

As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the damage almost immediately.
