The telescope that points itself‎

I'll admit to using AI for things it was probably never designed for. When my van threw a fault I couldn't immediately figure out—one that seems notorious for trips back and forth to a repair shop—I ended up in a long (but cheaper) back-and-forth with an AI system, working through the symptoms. The same happened with a run of gutters and with stud framing in my house. It isn't magic, and perhaps more often than I'd like, it's wrong, but as a way of thinking through a problem with something that's read more manuals than I ever will, it has earned its place in the toolbox. So I read this next story with some sympathy and interest.

Improvisational theater, meditation and games support anxious teens‎

Adolescence is a key stage of development, characterized by heightened emotional vulnerability. According to the World Health Organization (WHO), one in seven young people ages 10–19 lives with a mental health condition. In this context, developing social and emotional skills offers a promising way to support both academic success and young people's ability to cope with the challenges of adolescence, particularly for those who are most vulnerable. Identifying approaches that are both effective and well suited to this age group is therefore an important priority.

A coral among the stars: New species discovered on Costa Rica's deep-sea seamounts‎

Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification. Bright yellow and tree-like, the coral was found growing some 360 to 529 meters (1,180 to 1,735 feet) beneath the surface of the Pacific. The discovery is described in the open-access journal ZooKeys.

Opposition to local data centers rises sharply, survey finds‎

As protesters rally against data center construction in dozens of states and New York and Texas pause the issuance of permits for large data centers, a new nationally representative survey finds that Americans' opposition to data centers in their communities has risen sharply since last spring.

Researchers develop new framework for understanding how emotions shape behavior online‎

Every day, billions of people scroll through social media posts, online reviews and news feeds filled with emotional content—from glowing five-star reviews to rage-inducing social media rants. Those emotions can quietly shape what people buy, what they believe and how they act.

Decoding smell: Study reveals how wind transforms odor signals‎

Humans trust dogs to help find missing people, and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.

A smarter way to track satellites beyond Earth's orbit‎

Most current space activities operate close to Earth in what is called near–Earth orbit. However, as more satellites and other infrastructure begin to extend beyond that region, maintaining situational awareness of those objects will be crucial.

Color-sensing yeast could make biofactories more programmable and precise‎

Baker's yeast is one of biotechnology's most important microorganisms. It has long been used to leaven bread and ferment beer. More recently, advances in synthetic biology have enabled engineered yeast to convert sugar into a wide range of products, including medicines, fuels and industrial chemicals. Yet even well-engineered yeast cells can be difficult to control in a precise and timely way.

Australia's plastic exports may deepen health risks in Indonesian communities‎

A new commentary in BMJ Global Health, co-authored by the George Institute, reveals that Australia exported 22,333 metric tons of plastic waste to Indonesia in 2023–24 alone, part of a wider crisis that has seen the country take in more than 200,000 metric tons of imported waste it cannot safely process. Up to 80% of it ends up burned or dumped.
