Room-temperature superconductors could revolutionize electronics – an electrical engineer explains the materials’ potential

Superconductors make highly efficient electronics, but the ultralow temperatures and ultrahigh pressures make them costly and difficult to use. Room-temperature superconductors promise to change that.

A shortage of native seeds is slowing land restoration across the US, which is crucial for tackling climate change and extinctions

Native plants help damaged landscapes by stabilizing soil, fighting invasive species and sheltering pollinators. Two horticulture experts explain what they’re doing to help develop new seed sources.

Israel’s military reservists are joining protests – potentially transforming a political crisis into a security crisis

Israel’s leader, Benjamin Netanyahu, has fired the country’s defense minister. That deepened the country’s crisis over proposed judicial reforms that even military reservists have protested.

Watermarking ChatGPT, DALL-E and other generative AIs could help protect against fraud and misinformation

In a world of increasingly convincing AI-generated text, photos and videos, it’s more important than ever to be able to distinguish authentic media from fakes and imitations. The challenge is how.

What is xylazine? A medical toxicologist explains how it increases overdose risk, and why Narcan can still save a life

Xylazine, or tranq, is increasingly being mixed with drugs like fentanyl or heroin and can be difficult to detect. Most people who use drugs are unable to tell if they have been exposed to it.

Presidential hopefuls are considering these 5 practical factors before launching their 2024 campaigns

Senators, governors, representatives and past presidents have to weigh multiple factors before declaring their 2024 run for president. Campaign financing is one of them.

How do superconductors work? A physicist explains what it means to have resistance-free electricity

Superconductors are materials that can transmit electricity without any resistance. Researchers are getting closer to creating superconducting materials that can function in everyday life.

Reaction to bronze sculpture of Coretta and Martin Luther King Jr. in Boston hasn’t been good – and that’s not bad for art that shatters conventions

A memorial to Coretta Scott and Martin Luther King Jr. has received stinging criticisms, but time will tell whether ‘The Embrace’ will endure as a cherished work of public art.
