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 ...

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it's becoming clear that the body is far more complex--and . ...

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 . ...

A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America. Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating. Researchers found . ...

Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help repair DNA, but when overproduced it starts cutting DNA ...

Animals from different species often rely on surprisingly sophisticated communication to work together, whether finding food, cleaning parasites, or gaining protection. New research suggests these interspecies "conversations" are flexible, evolved, . ...

A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, dust-filled starburst galaxies could account for a . ...

Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers. The method uses Shannon entropy to identify guesses that reveal the most about the hidden word. Each guess is .. ...

A newly identified molecule called OLE helped restore the brain's immune cells to a more protective state in Alzheimer's models. The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach.

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn't expanding wildly fast. The study suggests that the very shape of space-time may protect the ...
