Phys.org / Arctic shipping alters cloud formation, study finds

A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region.

Tech Xplore / Microscopic image changes can bypass AI guardrails, nearly doubling unsafe responses

It may look like a picture of a panda bear to you, but to your business's AI agent, it can act like a skeleton key, bypassing safety safeguards and potentially causing the model to generate harmful, misleading or policy-violating ...

Tech Xplore / Food waste can become jet fuel through simpler refining and 50-50 blending

The aviation industry accounts for a large portion of global greenhouse gas emissions. Biobased, sustainable aviation fuel (SAF) can mitigate climate impacts, but transitioning to SAF faces critical supply chain constraints. ...

Phys.org / Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this ...

Phys.org / Using less, living better: Demand-side climate action wins public support

Climate strategies are still judged largely across two dimensions: how much they cost and how many tons of CO2 they save. A new study published in Communications Sustainability argues that this narrow lens overlooks much ...

Phys.org / Titan and Pluto exhibit the same mysterious spectral feature—and researchers can't figure out its origin

Researchers are constantly sifting through new spectral data gathered by powerful telescopes, like the James Webb Space Telescope (JWST). Most of the time, when they identify spectral features—specific absorption or emission ...

Phys.org / How languages recycle parts of words to avoid confusion

Many languages recycle words, giving them different meanings. For example, in English, "run" can mean to move quickly but also to manage something, like "run a company." In Spanish, "lengua" is both the word for tongue and ...
