New research suggests obesity may leave a long-lasting “memory” on the immune system, even years after weight loss. Researchers have found that obesity may leave a lasting biological “memory” in the immune system, potentially increasing the risk of obesity-related diseases years after a person loses weight. The findings come from a decade-long study published in […]
Breakthrough Parkinson’s Drug Targets Disease at Its Genetic Roots
An experimental gene-silencing therapy safely lowered LRRK2 protein levels in an early Parkinson’s trial, but its effect on symptoms remains untested. An experimental medicine built to silence a gene closely associated with Parkinson’s disease has produced encouraging results in its first clinical test in people, according to a study published in Nature Medicine. The treatment, […]

Just 4 Weeks of Simple Diet Changes Reversed Signs of Aging in Older Adults
Short-term dietary changes may reduce biological age in older adults, especially with lower-fat or more plant-based eating patterns. What if changing your diet for just a few weeks could make your body appear biologically younger? A new study from the University of Sydney suggests that older adults who reduced either dietary fat or animal-based protein […]
Scientists May Have Finally Solved Why Humans Are Right-Handed
Scientists say the mystery of why humans are so right-handed may trace back to our first steps on two legs. Why do humans overwhelmingly prefer their right hand while other primates do not? Scientists have debated that question for decades, but a new study suggests the answer may be rooted in two defining moments of […]
Physicists Found String Theory Without Even Looking for It
Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory. Imagine slicing an apple into smaller and smaller pieces. First you would reach molecules, then atoms, and eventually the subatomic particles inside them, including protons, quarks, and gluons. According to string theory, however, nature may continue […]

Ultra-Faint Dwarf Galaxies Could Unlock Secrets of the Early Universe
Tiny galaxies orbiting the Milky Way may hold clues to one of cosmology’s biggest mysteries. Ultra-faint dwarf galaxies are among the smallest known galaxies orbiting the Milky Way. Astronomers have long viewed them as ancient remnants from the early cosmos. Now, researchers at the Oskar Klein Centre and the LYRA collaboration have used a powerful […]
Massive Genetic Study Reveals Hidden Causes of Pregnancy Sickness
A major international study has uncovered several new genetic clues tied to hyperemesis gravidarum, a debilitating form of pregnancy sickness once widely misunderstood. The USC team that recently identified the hormone-encoding gene GDF15 as a major driver of pregnancy sickness has now linked nine more genes to its most severe form, hyperemesis gravidarum (HG). Six […]
