A surprise toilet malfunction tested Artemis II—but the crew fixed it fast and is back on track for the Moon. NASA’s Artemis II astronauts recently dealt with an unexpected but important issue aboard the Orion spacecraft. After completing a proximity operations demonstration, which involves carefully maneuvering the spacecraft near another object to test navigation and […]
Surviving Burns May Have Changed Human Evolution
Frequent burn exposure may have driven human genetic adaptations that improve healing but worsen severe injury outcomes. Humans may have been shaped in part by an unexpected force: repeated exposure to high-temperature burn injuries. New research suggests this long history has influenced how the body repairs damage, responds to infection, and reacts under severe trauma. […]
Scientists Discover Hidden “Footprint of Death” That Could Transform How We Fight Disease
Scientists have uncovered a previously unknown feature of cell death that reshapes how the immune system identifies and clears dying cells. Scientists at La Trobe University have identified a previously unknown way viruses may spread through the body, a finding that could inform the development of more effective treatments. The study, published in Nature Communications, […]
Scientists Uncover Massive Climate Secret Beneath Sweden’s Forests
Undisturbed boreal forests may hold far more carbon than expected. Earth’s vast northern forests may be doing far more to slow climate change than scientists once realized. New research from Sweden shows that untouched, old-growth boreal forests store dramatically more carbon than the managed forests that often replace them, raising new questions about how forests […]

“We Were Truly Astonished”: New Discovery Rewrites Earth’s Origin Story
A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed almost entirely from nearby material rather than distant sources. Planetary scientists have long debated the origin of the material that formed Earth. Although our planet sits in the inner Solar System, many researchers have estimated that between […]
A Simple Nose Swab Could Detect Alzheimer’s Years Before Symptoms Appear
A simple nasal swab may offer an unexpected window into the earliest biological signals of Alzheimer’s disease. Alzheimer’s disease affects millions worldwide, but it is most difficult to detect in its earliest stages, when treatment may be most effective. A new study from Duke Health suggests that a simple outpatient nasal swab could reveal early […]

Scientists Warn: Vaping Likely Causes Cancer
A sweeping scientific review is raising new concerns about the long-term health effects of vaping. Nicotine-based e-cigarettes may pose a serious cancer risk, according to a major new review that challenges the long-standing perception of vaping as a safer alternative to smoking. The study, led by UNSW Sydney and published in Carcinogenesis, brings together evidence […]
