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

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 obesity treatment if future human trials prove successful.

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

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, potentially overcoming major limitations in today's electronics. The discovery could lead to faster computers, more efficient data centers, and breakthroughs in quantum technology.

NASA is racing against time to save the Hubble Space Telescope

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 innovative ways to boost Hubble into a higher orbit, upgrade its capabilities, or safely dispose of it when its mission finally ends.

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

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 tiny squeeze dramatically changes the magnetism of exotic materials

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.

Permanent daylight saving time has a dark side, scientists warn

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

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 surprising discovery could help aging muscles repair themselves

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.

Limited cold stress during pregnancy could lead to increased lamb birth weight, survivability

Research out of South Dakota State University has highlighted a potential connection between limited exposure to cold stress during pregnancy and birth weight. The work showed that shearing ewes at day 50 of gestation, rather than after 100 days, resulted in larger and heavier lambs at birth.

Tiny melt traces shed light on the Colorado Plateau's explosive past

Deep beneath Earth's surface, some minerals hold clues to processes that happened millions of years ago. One such mineral is lawsonite, which forms under high pressure and relatively low temperatures. What makes it significant is its ability to store water within its crystal structure and carry it deep into Earth as tectonic plates move beneath one another.

Scientists develop novel model to forecast internal solitary waves from multiple sources in the Sulu Sea

A research team led by Professor Li Xiaofeng from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has developed a model to forecast internal solitary waves originating from multiple sources in the Sulu Sea. The model combines physical equations and satellite observations to predict wave arrival times and crest positions across this complex marine environment.

Seagrass helps Biscayne Bay's mangroves keep up with rising seas

The mangroves of Biscayne Bay have been getting help from an unlikely neighbor—the seagrass meadows just offshore. Dead seagrass blades and seaweed drift loose until the tide carries them into the mangroves, where they pile up, rot slowly and then become part of the ground.
