The study tested whether a small electrical pulse to the brain can change how people feel and react when they are anxious. Researchers used a special test that makes people feel uneasy by breathing in air with 7. 5% carbon dioxide. This is a common way to create anxiety safely in a lab. They turned
Wild mustard species have found clever ways to live in water‑logged places. When rain turns a field into a pond, these plants do not simply drown. Instead they grow special air‑filled tissues that let oxygen reach their roots. Some species develop extra roots on the surface, while others ch
The world watches missiles fly over the Middle East and sees the obvious damage: people hurt, leaders lost, oil prices jump. But a hidden cost is also growing, one that shows up not on a battlefield map but in laboratories and libraries. In June of last year, two missiles from Iran hit the Weizma
The idea that moving clocks forward or back might help wildlife is surprising, but research shows it can make a real difference for animals that share roads with humans. In the United States, traffic accidents involving deer and other large mammals happen over a million times each year. These collis
In forests of North Patagonia, scientists looked at how the shape of a plant’s root system affects tiny roots that do most of the work. They studied eight perennial herb species, half of which grow a single main root (tap‑rooted) and the other half grow many small roots from the stem (adventitious).
A new study shows how changing the space inside a special material can help store more magnesium ions. The material is made of niobium and sulfur atoms arranged in a quasi‑one‑dimensional pattern. By adding large organic ions called BMPyrr⁺, the layers of this material open up. This opening lets mag
The new sensor uses a single CRISPR enzyme, Cas12a, to spot damaged DNA without extra steps. A specially designed double‑stranded DNA keeps Cas12a quiet until the enzyme uracil‑DNA glycosylase (UDG) removes a uracil base. When UDG cuts the uracil out, the balance of the DNA changes and Cas12a
The editorial team has opened a new section that shines a light on cutting‑edge studies about bacteria, their biology and the drugs we use against them. They invite readers to explore a collection of papers that push the boundaries of what we know about how microbes work. Each article offers f
A new online resource gathers a wide range of information on more than 1, 000 cactus species. The collection links physical traits, where each plant lives, the climates they occupy, and their evolutionary relationships. It also offers data on how large each species’ range is, the speed at which new
NASA has announced big changes to its Artemis plan, aiming to get more rockets flying and reduce risks. The new strategy keeps the goal of landing astronauts on the Moon in 2028 but rearranges how that happens. Instead of waiting three years between launches, the agency now wants a flight every ten
