NASA-European Sea Level Mission Homes in on El Niño

Sea level data from a satellite launched by NASA and European partners shows that a swell of warm water hundreds of miles wide has arrived in the Pacific Ocean off the coast of South America, a sign that El Niño will likely emerge later in the year. Because water expands as it warms, a rise […]

NASA’s Webb Reveals Black Hole That Formed Before Its Galaxy

Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities. But it’s hard […]

Scientists break 30-year superconductivity record at normal pressure

Scientists at the University of Houston have shattered a long-standing superconductivity record, creating a material that can conduct electricity with zero resistance at the highest temperature ever achieved under normal pressure conditions. Their breakthrough pushes superconductivity to 151 Kelvin (minus 122°C), beating a record that stood for more than 30 years.

Tiny “sesame” sea slug discovered in Taiwan turns out to be a new species

A sea slug smaller than a sesame seed has turned up in Taiwan’s coastal waters — and it’s so tiny and unusual that scientists realized they had discovered a completely new species. Named Thecacera sesama after its black-and-yellow “sesame-like” appearance, the translucent nudibranch was first spotted during a casual dive and later identified with help from a sea slug expert on Facebook.

New drug could finally stop deadly fatty liver disease

Scientists at UC San Diego have unveiled a potentially game-changing treatment for MASH, a severe fatty liver disease affecting millions worldwide. The experimental drug, ION224, blocks a liver enzyme that drives fat buildup and inflammation, two key forces behind liver damage. In clinical trials, patients showed striking improvements in liver health, even without losing weight.

This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, […]

New laser heat treatment could stop blindness before it starts

A new experimental treatment could finally offer hope for millions of people with dry age-related macular degeneration — one of the leading causes of blindness in older adults. Researchers at Aalto University discovered a way to gently heat tissue at the back of the eye using near-infrared light, triggering the cells’ natural “cleanup and repair” systems before major damage occurs.

NASA’s Webb telescope discovers a planet where rock clouds vanish every night

A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed.

NASA’s Fermi telescope reveals the power source behind monster supernovae

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.

Blossoming among spoil heaps: how 1,000 years of lead mining gave birth to banks of pansies and pennycress

Calaminarian grassland is a rare habitat where plants thrive in soils contaminated by heavy metals. But should these toxic meadows be protected or allowed to fade away?At first, the small purple flowers are hard to spot in the weak May sunshine. Slowly the drifts of delicate mountain pansies, along with the white rosettes of alpine pennycress, begin to jump out, scattered across an area little bigger than a football pitch, on the banks of the River Allen in Northumberland.This is a pocket of cal

Scientists say guava juice could make iron supplements work better

Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice — especially with iron supplements — experienced noticeable increases in hemoglobin levels. Since guava contains far more vitamin C than oranges, scientists believe it could become a simple, affordable nutrition tool in regions where anemia is widespread.

Earth’s orbital wobble triggered rapid climate chaos during the dinosaur age

New research suggests Earth’s climate can swing wildly on surprisingly short timescales — even during hot, ice-free greenhouse periods. By studying ancient sediments from the Late Cretaceous, scientists uncovered repeating climate shifts tied to tiny changes in Earth’s orbital wobble. These cycles may have repeatedly pushed the planet between humid and arid states every few thousand years.
