A tiny laser beam could make computer memory 1,000 times faster

Scientists at UC San Diego have developed a surprising new way to store digital information using light instead of magnets, potentially paving the way for smaller, faster, and more energy-efficient memory devices. By precisely shaping and shrinking an ultrafast laser beam, researchers demonstrated that they could switch magnetic states in a material, the basic process used to write digital data. The technique could potentially operate more than 1,000 times faster than conventional magnetic switching methods.

A psychologist explains his theory for why orcas are attacking boats

Over the past six years, orcas have made headlines for a unique behavior: Some individuals have repeatedly damaged or destroyed rudders on boats. The behavior has prompted a wide range of explanations, including that it's playful, a form of revenge, a warning against getting too close to the pod, or even a type of cultural transmission, in which one orca observes another interacting with a boat and then imitates it. But Christian Frings, a cognitive psychologist who studies how humans control their actions, thinks it could be deliberate. While Frings, who is also chair of general psychology and methodology at Trier University in Germany, does not study orcas directly, he believes that theori...

Do spiders dream? Scientists just found a surprising clue

Scientists have discovered that spiders may sleep in ways surprisingly similar to humans, complete with distinct sleep stages and a dream-like REM state. Researchers at the University of Bonn studied the Australian jumping spider Portia fimbriata, a remarkably clever hunter known for its sophisticated strategies. By recording the spiders over several days and nights, they found clear evidence of regulated sleep, including a REM-like stage marked by eye movements and muscle twitches.

Scientists discover a surprising clue to why some brains resist Alzheimer’s

Why do some people stay mentally sharp even when their brains show signs of Alzheimer’s disease? Scientists in the Netherlands may have uncovered an important clue hidden in a rare group of immature brain cells. Researchers discovered that these cells remain present even in people over 80, but their behavior differs dramatically between those who develop dementia and those who remain cognitively healthy.

Mayo Clinic discovers new ways to fight the “zombie” cells that drive aging

Mayo Clinic scientists have uncovered surprising new insights into “zombie cells,” aging cells that linger in the body and contribute to inflammation and disease. Seven studies reveal why these cells are harmful and identify new strategies for targeting them, including a natural compound found in tomatoes. In aging mice, experimental treatments reduced inflammation and improved physical and brain health. The findings could open the door to therapies that combat some of the biological processes behind aging.

1.9-million-year-old discovery rewrites the story of human evolution

New evidence suggests that early humans reached the Jordan Valley at least 1.9 million years ago, hundreds of thousands of years earlier than scientists previously thought. Advanced dating methods revealed that the ‘Ubeidiya site is roughly as old as the famous Dmanisi site in Georgia, placing both among the earliest known human settlements outside Africa.

NASA's Swift observatory ends 22-year mission, will crash to Earth 'in the next few weeks'

A pioneering NASA space telescope is no more. In sad news for Swifties everywhere, the Neil Gehrels Swift Observatory has officially ended its mission after more than 20 years of tracking the most powerful explosions in the universe since the Big Bang. According to a NASA announcement, the Swift team shut down the telescope's science operations Tuesday (Oct. 20) after the observatory fell too low in its orbit to continue taking reliable measurements of the cosmos. In the coming weeks, Swift will drop even further, eventually passing a point of no return and taking a fiery plunge through Earth's atmosphere.The observatory is the latest victim of intense solar activity, which increases the dra...

A neglected particle from the dawn of time could explain why everything in the universe exists

A neglected "ghost particle" may have dominated the universe right after the Big Bang ‪—‬ changing how the cosmos expanded in its first moments and reshaping the conditions under which matter won out over antimatter, a new study suggests. In other words, it may explain why anything exists at all.The particle, a hypothetical "right-handed" neutrino, briefly could have held more energy than everything else in the infant universe combined, which would have sped up cosmic expansion and delayed key particle interactions, the study proposes. The research was published Sept. 8 in the journal Physical Review Letters.Neutrinos are ghostly particles that rarely interact with anything. A typical neutri...

'A potential glimpse into the future': Climate change has triggered 'permafrost landslides' with house-size blocks of ice in Canada

There's a new type of landslide affecting northern latitudes, and it could affect more areas as the planet continues to warm. These landslides, called permafrost detachment slides, occur in areas with relatively thin permafrost and seem to be a long-term impact of wildfire in these environments, according to a paper published Sept. 23 in the journal Geophysical Research Letters. Such slides have not been observed in the region before and may be unprecedented over the past 10,000 years or more, said study leader Joseph Young, who completed the work as part of his doctoral degree at the University of Alberta. "It has been stable, and then it just flipped a switch, essentially," Young told Live...

Colorectal cancer cases in kids have risen sixfold over past 2 decades ‪—‬ researchers are racing to understand why

More children, teens and very young adults are being diagnosed with colorectal cancer in the United States, and new research suggests they often experience aggressive forms of the disease. While diagnosis rates are rising, the disease is still rare among young people. Colorectal cancer, which affects the lower intestines and rectum, is largely a disease of age: 55% of all colorectal cancers are diagnosed in people over 65, and only 16% occur in people ages 49 or younger, according to a 2026 study published in the flagship journal of the American Cancer Society. Only a few hundred cases per year are diagnosed in people under age 21 in the U.S. Nevertheless, the numbers of cases in the very yo...
