SLAC scientists find conclusive proof of a mysterious third type of magnetism

14:59
For nearly 90 years, scientists believed magnetism fell into just two categories, but researchers have now confirmed a remarkable third type called altermagnetism. Using specialized X-rays, they uncovered a unique magnetic signature that proves these materials behave differently from conventional magnets. Altermagnets combine stability with the ability to efficiently carry information, potentiall…

NASA is racing against time to save the Hubble Space Telescope

14:59
NASA is exploring a daring plan to save the legendary Hubble Space Telescope from its eventual fiery plunge into Earth's atmosphere. After more than 35 years of groundbreaking discoveries, Hubble is slowly losing altitude, and without intervention, it could fall back to Earth as early as 2033 or 2034. To keep the iconic observatory operating, NASA is asking private space companies to propose inno…

MIT scientists break a 20-year rule and unlock never-before-seen crystal structures

14:59
MIT scientists have challenged two decades of conventional thinking by discovering that flexible molecular connections, rather than rigid ones, can unlock entirely new ways to arrange nanoparticles. The breakthrough could lead to a new generation of designer materials with unusual properties and applications in electronics, medicine, and energy.

A surprising discovery could help aging muscles repair themselves

14:59
Scientists have discovered a compound that transforms a natural muscle-repair protein into a more powerful version dubbed "Super HGF," more than doubling its ability to bind to a key receptor while protecting it from age-related chemical damage. The breakthrough, supported by early mouse experiments, could eventually help combat muscle loss and preserve strength as people age.

AI helps Stanford scientists discover a “natural Ozempic” with a surprising advantage

14:59
Stanford researchers have discovered an AI-identified natural molecule that dramatically suppresses appetite and promotes fat loss in animals, potentially offering an Ozempic-like weight-loss treatment without common digestive side effects or significant muscle loss. Called BRP, the molecule reduced food intake by up to 50% and targets a different brain pathway, raising hopes for a more precise o…

Permanent daylight saving time has a dark side, scientists warn

14:59
A new study warns that permanent daylight saving time could force American children to make at least 2 billion additional school commutes in darkness, potentially increasing safety risks and disrupting their biological clocks. Researchers found that fatal crashes involving school-aged pedestrians were roughly twice as likely during dark mornings as after sunrise.

Scientists may have finally explained why our brains and bodies are cross-wired

14:59
Scientists propose that the brain’s mysterious cross-wiring, which connects each hemisphere to the opposite side of the body, may have originated more than 500 million years ago in the visual systems of ancient fish. Rather than evolving for a specific advantage, this unusual arrangement may simply be a legacy of evolution building new brain circuits on an ancient foundation.

A tiny squeeze dramatically changes the magnetism of exotic materials

14:59
Scientists have discovered that a simple mechanical squeeze can dramatically alter the magnetic properties and electrical behavior of exotic materials called altermagnets. The surprising breakthrough could open the door to faster, more energy-efficient electronics and new technologies for quantum computing.

A hidden star is plowing through Betelgeuse’s atmosphere, new evidence suggests

5:57
Something mysterious is disturbing Betelgeuse, and astronomers believe they have identified the culprit: a hidden companion star called Siwarha. New radio observations reveal that the smaller star may be plowing through Betelgeuse’s enormous atmosphere, creating disturbances that subtly stretch and distort the red supergiant’s shape.

Gene editing could replace a lifetime of medication, but there's a catch

5:57
A single gene-editing treatment could someday protect against heart disease, high cholesterol, and other common conditions for decades, potentially replacing lifelong medications. But scientists warn that permanently altering genes introduces risks that could take years to emerge, making long-term safety a critical challenge.

Scientists trick cancer cells into making the drugs that kill them

5:57
Scientists have developed a promising new cancer-fighting strategy that uses carbon monoxide naturally produced by tumor cells to manufacture powerful drugs inside the cancer cells themselves. Early laboratory experiments suggest the technique could selectively attack cancer while sparing healthy cells, potentially paving the way for safer chemotherapy alternatives.

Kids who eat more ultra-processed foods show a troubling brain response

5:57
A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's reward system when viewing tempting foods like cookies and French fries. These heightened brain responses were linked to g…

NASA smashed into an asteroid. Now Hera is closing in to see what happened

3.listopadu
Europe’s Hera spacecraft has captured its first clear view of two asteroids involved in NASA’s historic 2022 experiment to redirect a potentially dangerous space rock. Now approaching the pair, Hera will investigate the mysterious aftermath of the collision and uncover why the asteroid shifted far more than scientists predicted.

NASA’s Voyager 1 is about to reach a historic one-light-day milestone

3.listopadu
NASA’s Voyager 1 is approaching an extraordinary milestone nearly 50 years after its launch, even as engineers battle dwindling power and mysterious technical problems. A clever energy-saving maneuver has extended the spacecraft’s scientific mission, while an unexplained 48-hour communications blackout recently gave NASA a scare. On November 18, Voyager 1 will reach a distance of one light-day fr…

Scientists identify two overlooked skills that predict reading success

3.listopadu
A massive new study reveals that intelligence plays a surprisingly limited role in children's reading success, while visual processing showed no meaningful connection at all. Instead, the strongest predictors are sound recognition, vocabulary, and background knowledge, offering new clues about how to help struggling readers.
