Water is a precious resource, and scientists are working hard to make filters that can clean it faster and more reliably. One type of filter, called a nanofiltration membrane, is especially good at separating useful molecules from waste. The key to making these membranes work well lies in the tiny b
Leanne Fan, an 18‑year‑old senior from Westview High School in San Diego, has turned her bedroom into a mini laboratory. She built a low‑cost device that spins samples to mimic the weightlessness astronauts feel in orbit, allowing her to study how living cells respond when gravity is absent. Inst
Mice were trained to decide whether a picture meant “go” or “no‑go. ” Scientists recorded the electrical activity of single neurons in ten brain areas for weeks. They used ultra‑flexible wires that stayed attached to the mice’s heads, so they could watch how each region talked to the others du
The study shows that if a matrix filled with 0s and 1s has either a small γ₂‑norm or a small normalized trace norm, it must hide a large square of all 1s or all 0s. This confirms a claim made by Hambardzumyan, Hatami, and Hatami. The researchers also explore other patterns that arise when Boolean ma
The new Focus Issue on molecular microbiology is a celebration of science that improves health. Here are some standout papers from the recent archive that show how basic research can lead to real benefits for people. First, a study revealed how tiny changes in bacterial DNA help microbes survi
This study looked at how rocks under farmland can put harmful metals into soil and rice. Three common rock types were studied: phosphorite, black shale, and basalt. The researchers measured the amounts of lead, arsenic, mercury, cadmium, zinc, chromium, nickel and copper in the soil and in rice grai
Scientists have found that bananas grown close to the Doce River estuary in Brazil could be risky for children under six. The danger comes from metals left over after a 2015 dam collapse that released mining waste into the area. Researchers from Brazil and Spain tested bananas, cassava, and cocoa pu
A new German invention has pushed the limits of gas turbines. Researchers at Karlsruhe Institute of Technology built a compressorless turbine that ran for 303 seconds—longer than NASA’s previous record of 250 seconds. Unlike conventional turbines, which waste half their energy compressing air,
Scientists have long used a material called Me‑4PACz, or Me4, as a layer that pulls holes out of inverted perovskite solar cells. The layer is handy, but it often clumps together in solution and does not spread well over the next layer. Because of this, the contact between layers is weak and the cry
"The journal has reached its eleventh year and is witnessing a surge in readership. It aims to stand out among open‑access publications by combining rigorous research standards with a welcoming approach for authors worldwide. Speed of publication remains a priority, so the community can quickly acce
