When climate risk hits home, people listen: Local details can enhance disaster preparedness messaging
A subtle change in how climate risk is communicated—mentioning a person's local area—can significantly increase attention to disaster preparedness messages, according to a new study by researchers at the Stockholm School of Economics and Harvard University, published in Nature
Scientists uncover a volcanic trigger behind the Black Death
A newly analyzed set of climate data points to a major volcanic eruption that may have played a key role in the Black Death’s arrival. Cooling and crop failures across Europe pushed Italian states to bring in grain from the Black Sea. Those shipments may have carried
A violent star explosion just revealed a hidden recipe for life
XRISM’s high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models predicted, showing that supernovae can be major sources of these life-critical
Garlic mouthwash shows shockingly strong germ-fighting power
Garlic extract is emerging as a surprisingly powerful contender to chlorhexidine, the long-standing “gold standard” in antimicrobial mouthwashes. A systematic review of clinical studies shows that higher-concentration garlic mouthwash can rival chlorhexidine in killing
Humans are built for nature not modern life
Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both health and reproduction. Evidence ranging from global fertility declines to
A sound defense: Noisy pupae puff away potential predators
Insect pupae hiss like snakes for defense. A Kobe University team now reveals the mechanisms, opening the door to further studies involving predator reactions to defensive sounds.
New fat-burning diabetes pill protects muscle and appetite
Researchers have developed a new oral drug that boosts metabolic activity in muscle rather than altering appetite like GLP-1 drugs. Early trials suggest it improves blood sugar control and fat metabolism while preserving muscle mass, with fewer side effects. Because it acts
Researchers solve a century-old North Atlantic cold spot mystery
A century-old North Atlantic cold patch is now linked to a long-term slowdown in the AMOC, the climate-regulating conveyor belt of ocean water. Only weakened-AMOC models match observed temperature and salinity patterns, overturning recent model trends. This slowdown affects
Study measuring impacts of deep-sea mining machine finds abundance of animals at the site decreased by 37%
A new report reveals the results of a study exploring biodiversity in a region targeted for seabed mining—capturing baseline data, tracking natural changes and assessing the impacts of a polymetallic nodule mining machine. This represents the largest study of the impacts of
Membrane 'neighborhood' helps transporter protein regulate cell signaling
When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways accidentally, cAMP levels must be maintained around their point of origin and at
Impossible translations: Why we struggle to translate words when we don't experience the concept
If you are fluent in any language other than English, you have probably noticed that some things are impossible to translate exactly.
Scientists reveal a surprising new timeline for ancient Egypt
A new radiocarbon study has clarified the timing of the colossal Thera eruption, placing it before Egypt’s New Kingdom. Researchers analyzed artifacts tied to Pharaoh Ahmose, gaining rare access to museum materials. Their results favor a younger chronology for early 18th
Scientists say this viral rosemary skincare trend actually works
Researchers have found scientific support for the viral claim that rosemary can improve wound healing. Carnosic acid, a natural antioxidant in rosemary, promoted scar-free healing in mice by activating a nerve sensor tied to regenerative repair. Rosemary proved more potent and
