Earth and Mars: Built from different cosmic recipes

Four and a half billion years ago, Earth and Mars were born in the rotating cloud of gas and dust that would eventually become our solar system. Yet exactly how the planets formed remains one of the most disputed questions in planetary science.

Alpine bacteria show unexpected ability to fight viruses

A silent, long-running competition has been taking place in Swiss alpine lakes for millions of years, killing trillions of organisms every day without anyone noticing. This competition between bacteria and viruses pushes both into a relentless evolutionary battle.

Study: Paid internships deliver strong payoff early in careers

A new national study co-authored by UW–Madison School of Education professor Mindi Thompson, who directs the university's Center for Research on College‑Workforce Transitions (CCWT), offers evidence that paid internships give college graduates a lasting advantage in earnings,

As I said… How intonation influences perception

"Between the lines"—that's how we describe unspoken messages that the actual text may omit but that are conveyed, for example, through word choice or tone of voice. A research team led by the Max Planck Institute for Empirical Aesthetics (MPIEA) in Frankfurt am Main, Germany,

Laser-made muons produce first images of dense objects

Muons are constantly being created as cosmic rays collide with molecules in Earth's upper atmosphere. With their ability to penetrate far into dense, solid materials, these cosmic muons are often used to image the insides of objects that are otherwise hidden from view. However,

The north pole of Mars is less dusty than scientists thought

Although Mars may have once resembled Earth, the rocky red planet now appears far from hospitable. Still, certain details—such as ice-bound water—pique researchers' curiosity. As on Earth, ice on Mars contains valuable records of past climate that could reveal whether the

More cats: The key to happy countries?

National happiness is influenced by complex relationships beyond basic economic factors, according to a study by Javier I. Borráz-León of the Secretariat of Science, Humanities, Technology, and Innovation in Mexico City and colleagues.

Ocean heatwaves are hiding months of extra warming

Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on average, potentially overlooking

Mulberry may reshape gut bacteria and influence metabolism

Mulberry compounds may reshape the gut microbiome in ways that support intestinal health and metabolism, with some combinations showing especially strong effects in animal studies. However, the results vary depending on the plant part and processing method, and the benefits
