A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently。 In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect。 High-fructose corn syrup triggered a stronger response and was preferred by the animals

Researchers found that twisting layered sheets of hexagonal boron nitride can dramatically change the light produced by quantum emitters embedded within the material。 The technique offers an unexpected new level of control over components that could power future quantum computers, communications systems, and sensors

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most。 When researchers temporarily switched off these neurons in mice, the animals became unusually distractible—similar to what is seen in ADHD—but regained normal f

A clever nanoscale redesign may have solved one of superconductivity’s biggest problems。 Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years。 Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds。 If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—

A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1。79 million years ago。 Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintained by human ancestors

Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads。 Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material。 If future studies confirm the roads are durable, the technology co

A hidden population of South African leopards has revealed a remarkable evolutionary story。 Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for roughly 20,000 years。 Surprisingly, despite their s

Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy。 The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago。 Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly

Apple rejected the suggestion its practices are anti-competitive, saying many customers rely on third-party alternatives

For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen。 New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth and humidity, and dedicate entire teams of attendants to raising future

The tech giant has consistently stood by its Majorana chip research despite scepticism from some experts in the field

Scientists have uncovered a surprising new twist in what happens when cells die。 As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains。 But researchers found that influenza viruses can exploit this process, hiding inside these microsc

The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into

Astronomers have finally cracked the mystery of the famous “Pink Planet,” a strange world 57 light-years away that has puzzled scientists for more than a decade。 Using the James Webb Space Telescope, researchers discovered that its atmosphere contains water vapor, methane, carbon dioxide, ammonia, and something never directly confirmed before in su

Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected。 Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw mate

NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways。 The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth

Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries。 If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative to lithium for EVs and large-scale energy storage
