Tiny plastics in drinking water may be making dangerous bacteria stronger

Tiny plastic particles in drinking water may be doing more than contaminating the environment. New research suggests nanoplastics can actually help harmful bacteria survive by strengthening the slimy biofilms they form inside water systems. These tougher biofilms become more resistant to disinfectants, making them harder to remove and potentially increasing public health risks.

New Alzheimer's drug repairs DNA damage and reduces brain inflammation

A drug originally developed for spinal cord injury may offer a fresh approach to treating Alzheimer’s disease. In mouse studies, KCL-286 repaired dangerous DNA damage, reduced inflammation, and targeted multiple disease-related pathways instead of focusing on just amyloid or tau. Since it has already cleared an initial human safety trial, researchers believe it could move more quickly into Alzheimer’s clinical testing.

NASA's James Webb Space Telescope reveals a strange atmosphere on a hellish lava planet

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds.

Archaeologists found Homer's Iliad inside a 1,600-year-old Egyptian mummy

A 1,600-year-old mummy discovered in Egypt has revealed something archaeologists had never seen before: a fragment of Homer’s Iliad used during embalming. The papyrus was identified as part of the famous "Catalogue of Ships," one of the best-known sections of the ancient epic. Researchers say it is the first archaeological evidence of a Greek literary text being intentionally incorporated into the mummification process, adding a fascinating new chapter to the history of both literature and ancient burial customs.

Why have humans collected crystals for 780,000 years? Chimpanzees may hold the answer

Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use.

New dark matter theory could solve multiple cosmic mysteries at once

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gravitational lensing.

Scientists discovered the brain doesn't make decisions the way we thought

A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward. This more dynamic view of brain function could help engineers design future AI systems that think more like biological brains while using far less power.

Future moon landings could wipe out clues to how life began on Earth

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution before it becomes widespread.

Alzheimer's tau protein has a surprising secret role in memory

Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the recall of existing ones.

Why gold never tarnishes has finally been explained

Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold. Beyond explaining why gold jewelry stays bright for generations, the finding could help scientists create more powerful gold-based catalysts for manufacturing and clean energy.

Rare fossil goose rewrites the story of New Zealand's giant birds

Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese evolved from much more recent arrivals, revealing a far more dynamic evolutionary history than once believed.

Scientists just debunked a dangerous baby rattlesnake myth

A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more serious bites. The team also uncovered how the myth spread through decades of inaccurate news reports and misleading quotes from trusted sources.

Scientists finally crack nature's secret for building better cancer drugs

Researchers have cracked the code behind bacteria's ability to naturally manufacture multiple versions of powerful anti-cancer drugs. The discovery could make it much easier to engineer new cancer treatments inspired by nature, including improved versions of existing medicines.
