Haunting Hubble telescope image captures cosmic cycle of destruction and creation — Space photo of the week
Quick factsWhat it is: The nebula LHA 120-N44Where it is: 160,000 light-years away, in the constellation DoradoWhen it was shared: Sept. 3, 2026It looks like a gigantic hole punched through a cloud, but this spectacular new image from the Hubble Space Telescope captures something more complicated: a cosmic cycle of destruction and creation, with one generation of stars tearing apart its birthplace while simultaneously helping a new generation form.LHA 120-N44 (N44, for short) is a nebula that lies about 160,000 light-years away in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way. From Earth, it appears in the constellation Dorado. This enormous, empty-looking region measu...

Why do cats lick each other?
In a multicat household, it's common to see one cat licking another. When some people see this behavior, known as allogrooming ("allo" means "another individual"), they assume it's a sign of friendship. But is that really the case? Are there hidden, more complex reasons for why cats lick each other?While research into allogrooming is ongoing, scientists have suggested different explanations for why cats lick each other, including some social reasons and some more practical ones.Social bonding or social tension?The historical view, based on observations of free-roaming-cat colonies, was that allogrooming is a sign of affection and helps cats create and maintain bonds with other cats in their ...

Venus’s pale yellow clouds may hide something surprisingly dark
A century-old mystery in Venus’s clouds just became more intriguing, as scientists calculated how strongly the unidentified material behind its dark ultraviolet patterns must absorb light. The results sharply narrow the possibilities and could help future spacecraft determine whether the mysterious substance is organic, inorganic, or something unexpected.

Scientists find water was fueling volcanoes 3 billion years ago
Ancient rocks from Western Australia suggest water was reaching deep inside Earth more than three billion years ago, long before modern plate tectonics may have fully developed. Researchers propose that water-rich pieces of crust periodically sank into the mantle through a process they call “dripduction.” The buried water then helped produce magma and volcanic eruptions.

A hidden compound in healthy foods may worsen IBD
A natural compound found in foods such as spinach, almonds, and sweet potatoes may aggravate gut inflammation in people with Crohn’s disease and ulcerative colitis because their intestines appear to handle it differently. Researchers say the finding could open the door to lower-oxalate diets or microbiome treatments tailored specifically to people with IBD.

Ozempic and Wegovy may raise hair loss risk in some men
GLP-1 drugs such as Ozempic, Wegovy, and Zepbound may increase hair-loss risk by 7% in men who are already genetically susceptible to male-pattern baldness. The findings suggest thinning hair may not be caused only by rapid weight loss and could also reflect a biological link between GLP-1 activity and hair follicles.

Scientists discover a hidden switch that shuts down inflammation
Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential new treatments for chronic inflammatory diseases.

Japan's Hayabusa2 achieves first-ever laser ranging experiment with an asteroid
The Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft reached another milestone this summer, a first for space agencies. On Sunday, July 5, the probe conducted the first successful laser-ranging experiment during a flyby of asteroid Torifune, the first exploration target of Hayabusa2's Extended Mission. This latest milestone will advance the capabilities of JAXA and other space agencies as they pursue future missions involving near-Earth asteroids (NEAs) and other deep-space objects.

A brief history of the hangover and its remedies—from cabbages to cloves and the lungs of a goat
Anyone who has ever woken up with a hangover will recognize its physical and psychological effects: headache, nausea, self-loathing, regret and perhaps even some shame at the uninhibited behavior that accompanied the intoxication.

Unified framework shows thermoelectric performance depends on more than the material itself
Thermoelectric materials can directly convert heat into electricity, making them promising for recovering waste heat from factories, vehicles and other sources. They can also transport heat when an electric current is applied through a phenomenon known as the Peltier effect. These properties have attracted considerable interest in energy-saving technologies and thermal management.

Silicon nanosphere coatings deliver glossy, nonfading color on 3D surfaces
"Color coatings are expected to provide vivid color, brightness, gloss and long-term durability, yet no existing technology satisfies all of these requirements simultaneously," says Kobe University materials engineer Hiroshi Sugimoto. Conventional coatings usually rely on relatively thick pigment layers that fade and add significant weight.

Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios
Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme weather, sea level rise, ecosystem loss and the risk of triggering irreversible climate tipping points, a new study, published in Science Advances, finds that reducing CO2 levels may have an unexpected effect. Climate simulations used in the study suggest that the Southern Ocean around Antarctica may switch from being an important carbon sink to being a prolific source of carbon.

Why do some salivary glands fail? Researchers point to hidden cell stress
For cancer patients undergoing head and neck radiation therapy, people living with Sjögren's syndrome, people with diabetes or older people, reduced saliva production and the resulting dry mouth are far more than uncomfortable. They can have major consequences for quality of life, making it difficult to eat, speak and swallow, altering taste perception, and increasing the risk of dental cavities and oral infections.

CERN finds gluons behaving strangely deep inside atomic nuclei
Physicists at CERN have found a new way to peer deep inside atomic nuclei and distinguish between two competing explanations for how gluons behave. Using the ALICE experiment at the Large Hadron Collider, researchers measured particle production at unprecedented spatial resolution, revealing structures as small as about one-quarter the size of a proton. At the smallest scales, they saw a surprising drop in J/ψ production that conventional “nuclear shadowing” struggles to explain.

Who really needs a heart calcium scan?
A 10-year study of more than 6,000 adults found that popular coronary calcium scans may add little to standard heart disease risk estimates for many people. But for patients with borderline or intermediate risk, the scans could make a meaningful difference by revealing who is actually more likely to develop heart disease.
