Researchers recovered more than 1,400 cannabis seeds and detected THC and cannabinol in preserved human hair, providing direct molecular evidence of psychoactive cannabis use at an elite tomb in southern Siberia dating back 2,800 years.
The 4.1 billion year old Teghaza 001 meteorite contains evidence of water altered Martian crust, unusual minerals and zircon crystals that let researchers examine a previously unsampled region from the earliest stages of Mars’s history.
Wisconsin has recorded 431 measles cases in 13 counties this year as vaccination coverage among kindergarteners sits near 85%. The infant’s death is the state’s first measles related fatality in more than 35 years.
A study of nearly 450,000 American adults linked occasional and frequent cannabis use with increased cardiovascular risks, particularly stroke, while researchers cautioned that the preliminary observational findings cannot establish that marijuana caused those conditions.
A large observational study linked GLP-1 medications to lower risks of diabetes, death and major cardiovascular problems among adults with prediabetes and obesity, though researchers caution that the preliminary findings cannot prove the drugs caused those outcomes.
Mice given olive oil before glucose had a smaller early rise in blood sugar, but researchers and nutrition experts caution that human studies are needed and balanced meals remain more important than treating olive oil as a quick fix.
Experts say balance can improve through a few minutes of consistent daily practice. Simple movements using body weight offer a safe starting point, while equipment such as pads, balls and sliders can add difficulty after a stable foundation develops.
After more than two decades observing powerful cosmic events, the Neil Gehrels Swift Observatory has fallen to Earth. Its archive, built from thousands of gamma-ray bursts, supernovae and other targets, is expected to fuel discoveries for decades.
A glass case inside an ordinary looking Austrian church holds the completely mummified remains of a parish vicar believed to have died in the mid to late 1700s, revealing a startling example of deliberate anthropogenic mummification.
Researchers found no blue whales during an intensive Galápagos survey, while unusually warm water and a mismatch between food and ideal temperatures raised questions about whether El Niño influenced their movements.
A study of more than 1,000 adults with likely long COVID found sustained improvement in 50.1% after three years, while 26.9% experienced complete symptom remission, offering hopeful evidence about patients’ recovery over time.
Up to 20% of people report out of body experiences, and Bart Simpson’s fictional brush with death mirrors many of their features. The resemblance is striking, but it does not prove that anyone actually left the body.
An experimental vaccine targeting common KRAS mutations failed to significantly extend disease free survival, but it produced lasting T-cell responses in nearly every vaccinated patient and offered clues for designing a larger phase 3 trial.
Evidence from a 1,500 kilometer journey across the Arabian Desert suggests that fresh water alone could not sustain early human occupation. Access to stone suitable for toolmaking may have determined where populations could settle.
Cychlorphine has reached about 25 states and has been linked to at least 122 US deaths, yet experts expect its spread to decline. Its potency, dangerous mixtures and resistance to common testing still create serious overdose risks.
A study examining school schedules and fatal crashes estimates that permanent Daylight Saving Time could produce more than 2 billion additional dark morning school commutes annually, raising concerns about pedestrian dangers for children.
An AI equipped acoustic buoy is listening for endangered southern resident killer whales as shipping noise disrupts their hunting and communication, while a voluntary vessel slowdown has reduced underwater noise by as much as 50%.
