Scientists have identified an enzyme that may act as a natural defense against the worsening of fatty liver disease, which affects an estimated 100 million Americans. The enzyme, called UBE2N, helps liver cells clear…
ESA’s Juice spacecraft raced past Earth on September 28, using our planet’s gravity to dramatically reshape its path toward Jupiter without burning much fuel. The flyby changed its direction by 20 degrees and increased…
Scientists studying Chang’e-6 lunar soil have discovered a previously unknown magnetic mineral in natural Moon samples: a form of metallic iron called γ-Fe. Found inside tiny impact-glass particles, the nanoscale iron…
Covered by Phys.org, ScienceDaily. Researchers have used some of the most detailed simulations yet of the early universe to investigate how the first stars and galaxies formed. Led by researchers at the University of Bath in the U.K., alongside…
The essential amino acid leucine can boost cellular energy production by protecting key proteins on mitochondria from being destroyed. The discovery reveals a new connection between nutrition and metabolism that could…
The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing…
Researchers have demonstrated that quantum fluctuations in supposedly empty space can strengthen superconductivity, raising the transition temperature of an ultrathin material by as much as 5.4%. The discovery opens the…
Vitamin C may do more than support the immune system. In a phase 2 trial of people with precancerous or low risk blood cancers, daily vitamin C did not slow abnormal cell growth, but it was linked to favorable changes…
Covered by Phys.org, ScienceDaily. Look up at the night sky with the naked eye and it may seem like it rarely changes. Yet the universe is in constant flux. Stars drift through space, orbiting the center of the Milky Way as planets orbit them. They…
Nearly 6 in 10 people with high blood pressure in a large England study had never been diagnosed or treated, and half of those already taking medication still had elevated readings. Researchers say a more proactive…
Mysterious 97-million-year-old magnetic fossils may be the oldest evidence of an animal using Earth’s magnetic field like a built-in GPS. Their sophisticated magnetic structure could have helped an unknown ocean…
JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically…
Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting…
High-risk MDS stem cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the…
Strength training may be one of the most powerful tools for staying independent as you age. Age related muscle loss, known as sarcopenia, can make everyday tasks harder while increasing the risk of falls, fractures, and…
Researchers say stress on Southern California’s San Andreas and San Jacinto faults has reached some of the highest levels seen in a 1,000-year simulation. Because both faults are highly stressed at the same time, the…
Weak sunlight can still damage skin DNA if you spend enough time outdoors, according to a landmark Australian study. Even UV doses too low to cause visible redness triggered cellular damage that could accumulate over…
Scientists at the University of Chicago have uncovered a surprising quantum state in the layered magnetic material Fe5GeTe2, where huge numbers of electrons move together unusually slowly while remaining quantum…
Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings…
Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is unusually good at…
