Popular sweeteners may leave effects that last for generations
Two widely used zero-calorie sweeteners, sucralose and stevia, may have effects that linger far longer than the sweet taste itself. In mice, researchers found that …
One injection could keep osteoarthritis drugs working for weeks
Scientists have created an injectable gel that can remain inside arthritic joints for weeks, slowly releasing medication while also improving lubrication. The approach could make …
Your waist size may reveal health risks BMI misses
A simple waist measurement may be nearly as effective as more complicated methods for detecting unhealthy levels of body fat. Researchers also found that BMI …
Scientists discover two superconducting states hiding as one
Scientists have uncovered hidden complexity inside two ultrathin superconductors that seemed much simpler than they really are. Niobium diselenide and tantalum disulfide appeared to have …
A “quantum bath” puts quantum entanglement on autopilot
Physicists have demonstrated a new way to entangle distant quantum bits without the constant measurements and active control normally required. The team created a “quantum …
Scientists challenge a 70-year-old “lizard brain” myth
A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that …
Fossil feet may be misleading scientists about human evolution
Wild monkeys in West Africa can climb vertical tree trunks using foot flexibility scientists did not realize they possessed. The discovery challenges a key assumption …
Scientists find why the liver may not heal even after you stop …
Alcohol-related liver disease may trap damaged liver cells in a regenerative limbo, preventing the organ from rebuilding itself even after drinking stops. Researchers linked the …
NASA’s Roman Space Telescope launches to reveal the Universe’s darkest secrets
NASA’s Roman Space Telescope has launched on a million mile journey to L2, where it will scan huge portions of the cosmos for clues about …
Rocky planets may have formed just 100 million years after the Big …
Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building …
Scientists discover diamonds can generate electricity
Diamond was thought to be incapable of producing electricity through mechanical deformation, but ultrathin flexible diamond membranes have now shown a strong and repeatable piezoelectric …
1.4-million-year-old footprints reveal a surprisingly large human relative
Ancient footprints in Kenya reveal that eight Paranthropus boisei may have traveled together 1.4 million years ago, with some individuals reaching surprisingly large, human-like body …
This strange “spacetime crystal” can suddenly become a black hole
Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in …
Common supplements rival antibiotics for severe gum disease
Omega-3 and low-dose aspirin matched the effectiveness of antibiotics in a year-long study of patients with severe gum disease, with both approaches helping about 58% …
IBM quantum computer solves classically intractable problem in 15 minutes
IBM and University of Chicago researchers have completed a quantum computation that leading classical methods could not practically reproduce. The system used 70 error-corrected logical …
HEPA air purifiers may boost brain function after just one month
Adults aged 40 and older performed about 12% faster on a test of executive function after using a HEPA air purifier at home for one …
Hundreds of hidden earthquakes found at Antarctica’s Doomsday Glacier
Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be …
Scientists discover a massive heat anomaly deep inside Mars
Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help …
A new recipe unlocks “impossible” nanocrystals for LEDs, implants, and superconductors
Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough …
Seven new frog species were hiding beneath Madagascar’s forest floor
Scientists have discovered seven new species of Madagascar’s elusive diamond frogs, using DNA from modern and century-old museum specimens to solve a long-running biological puzzle. …
Ancient Egyptian princesses were buried with weapons. Their bones reveal why
Weapons buried with ancient Egyptian princesses may have been more than ceremonial decorations. Researchers studying royal mummies from Dahshur found bone changes consistent with years …
Researchers unveil sustainable spirulina solution to vitamin B12 deficiency
Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow …
The next Cascadia megaquake could hit Oregon harder than expected
The Juan de Fuca plate beneath northern Oregon appears to be shallower than previously estimated, potentially making shaking from a future Cascadia megathrust earthquake significantly …
Some signs of quantum gravity may be an illusion
Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A …
