Hydroxyl radicals in UV-exposed water reveal surprising reaction pathway

How do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection. For example, with regard to the overfertilization of water bodies by intensive ...

How an internal plant 'thermostat' guides root growth in unpredictable temperatures

Plants can't move to escape the heat like humans can; they are forced to adapt. As temperatures fluctuate, one key survival strategy is the ability of roots to keep growing, allowing plants to access water and nutrients farther ...

Without the right tests, the best medicines make no difference

A new analysis from UC San Francisco argues that diagnostics—medical tests that match patients to the appropriate treatment—are being overlooked both in the United States and around the world. This is slowing progress against ...

What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

It's OK to love all the bees (the honey bees, too)

North America's bee populations are in trouble, but don't blame the honey bees. While some people argue that an overabundance of managed honey bees—those raised to help pollinate crops and produce honey—is causing native ...

Study rethinks the dropout-crime connection

Dropping out of high school has been linked to higher rates of delinquency and lower socioeconomic status, but thinking of high school dropouts collectively, as one group, is a flawed belief that could be affecting interventions. ...

This giant virus just gave up its atomic blueprint

A research group has successfully determined, for the first time in the world, the capsid (outer shell) structure of Melbournevirus—a member of the giant virus family—at a resolution of 4.4 Å using cryo-electron microscopy ...

Twin NASA control rooms support Artemis safety, success

Twin control rooms at NASA's Marshall Space Flight Center in Huntsville, Alabama, are actively supporting real-time mission operations in lunar orbit as part of the agency's Artemis II mission, helping ensure astronaut safety ...

Emperor penguins listed as endangered species: IUCN

The emperor penguin has been declared an endangered species as climate change pushes the icon of Antarctica a step closer to extinction, the global authority on threatened wildlife announced on Thursday.

Compact flat-lens system can generate nondiffracting bottle beams

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long distances. To overcome this challenge, ...

How noise limits today's quantum circuits

Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one perfectly, all the way down the line, producing an amazing result at the end. A quantum circuit is like ...

Addressing the Achilles' heel of marine protected areas

New research led by James Cook University (JCU) emphasizes that the success of marine protected areas (MPAs) depends largely on understanding and influencing people's behaviors within their borders. The study demonstrates ...
