Water Ice Found in Another Star System

Universe Today Feed - Thu, 05/15/2025 - 2:22am

Just as ice dominates the outer Solar System, blanketing the moons of giant planets and coating objects in the Kuiper Belt and Oort Cloud—astronomers using the James Webb Space Telescope have made a chilly discovery in a distant planetary system. The alien system HD 181327, 155 light-years away harbours significant deposits of both ordinary and crystalline water ice. They detected the ice in regions that are farther away from the star, with the outer area containing as much as 20% water ice.

Venus Might Have Tectonic Activity After All

Universe Today Feed - Thu, 05/15/2025 - 1:26am

One of the big differences between Venus and Earth is the lack of plate tectonics. While Earth's continents float on tectonic plates—constantly reshaping our world—Venus was previously thought to remain locked in a largely static crust with only occasional volcanic hotspots. But everything we thought we knew might be wrong! Researchers examining 30-year-old NASA Magellan spacecraft images have spotted what appears to be the smoking gun of tectonic activity on our hellish sister planet, potentially rewriting planetary science as we know it.

China's CO2 emissions have started falling – is this finally the peak?

New Scientist Feed - Wed, 05/14/2025 - 5:01pm
For the first time ever, China’s carbon dioxide emissions have declined even as its power demand has increased, a possible sign of a longer-term fall in emissions

Light-driven cockroach cyborgs navigate without wires or surgery

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:16pm
have created a new type of insect cyborg that can navigate autonomously -- without wires, surgery, or stress-inducing electrical shocks. The system uses a small ultraviolet (UV) light helmet to steer cockroaches by taking advantage of their natural tendency to avoid bright light, especially in the UV range. This method not only preserves the insect's sensory organs but also maintains consistent control over time.

Understanding carbon traps

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:16pm
As industries seek innovative solutions for carbon capture, scientists have turned to advanced materials that efficiently trap and store carbon dioxide (CO ) from industrial emissions. A recent study sheds light on the gas adsorption physics of so-called Calgary Framework 20 (CALF-20), a zinc-based metal-organic framework (MOF). While applying a combination of advanced techniques, the scientists reveal the material's unique adaptability under varying conditions.

New study offers insights into designing safe, effective nasal vaccines

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:12pm
Most vaccines -- and boosters -- are injected directly into muscle tissue, usually in the upper arm, to kickstart the body's immune system in the fight against disease. But for respiratory diseases like COVID-19, it can be important to have protection right where the virus enters: the respiratory tract. In a new study, researchers found that nasal vaccine boosters can trigger strong immune defenses in the respiratory tract, even without the help of immune-boosting ingredients known as adjuvants. The findings, researchers suggest, may offer critical insights into developing safer, more effective nasal vaccines in the future.

Drinking water, select foods linked to PFAS in California adults

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:09pm
A new study examined associations between diet, drinking water, and 'legacy' PFAS -- chemicals that were phased out of production in the US in the 2000s -- with blood samples from California residents. PFAS exposure was associated with consumption of seafood, eggs, and brown rice, but fewer other foods than suggested by earlier studies. PFAS levels were elevated among people who lived in areas where these chemicals were detectable in their drinking water supply, but lower than levels found in highly contaminated communities.

Superconductors: Amazingly orderly disorder

Computers and Math from Science Daily Feed - Wed, 05/14/2025 - 3:09pm
A surprising connection has been found, between two seemingly very different classes of superconductors. In a new material, atoms are distributed irregularly, but still manage to create long-range magnetic order.
