Ukrainians Are Defending the Values Americans Claim to Hold
Illustrations by Sergiy Maidukov I had no business going to Ukraine. The country didn't need another reporter to cover the war. Ukrainian journalists were already doing that much better than I could hope to, and so were plenty of foreigners. I had never set foot in Ukraine; I spoke neither of its languages; I was, my children told me, too old to be a war correspondent again. It would be completel

Scientists design and synthesize a new layered air-stable topological crystalline insulator candidate
Exploring novel topological materials and related phase transitions has been a central research theme in condensed matter physics and materials science. Topological materials with nontrivial anti-band crossings have attracted much attention. Hourglass fermion surface state, located at the vertex in the neck of an hourglass-like dispersion, enables exploration of remarkable topological phases, such

Researchers report counterintuitive friction effect
When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, or even fuse together. It is important for industry to understand such effects. After all, wear can destroy machinery and cost a lot of money.

Researchers construct most complex, complete synthetic microbiome
Key studies in the last decade have shown that the gut microbiome, the collection of hundreds of bacterial species that live in the human digestive system, influences neural development, response to cancer immunotherapies, and other aspects of health. But these communities are complex and without systematic ways to study the constituents, the exact cells and molecules linked with certain diseases

Keeping bacteria at bay in Hawaiian water bodies
During heavy rains, Hawaii's streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, and some of these bacteria can be harmful to human health. They can cause problems like gastroenteritis—also known as the stomach flu—as well as skin and respiratory diseases.
