Turning Old Smartphones into Battery-free, Biodegradable Ecosystem Monitors
If the goal of monitoring our natural resources is to protect the environment, shouldn’t the technology involved be sustainable as well?
Scientists Show How to Grow More Nutritious Rice That Uses Less Fertilizer
The cultivation of rice—the staple grain for more than 3.5 billion people around the world—comes with extremely high environmental, climate and economic costs.
This forgotten king united England long before 1066
Æthelstan, crowned in 925, was the first true king of England but remains overshadowed by Alfred the Great and later rulers. A new biography highlights his military triumphs, legal innovations, and cultural patronage that shaped England’s identity. From the decisive Battle of Brunanburh to his reforms in governance and learning,...
A tiny mineral may hold the secret to feeding billions sustainably
Rice, a staple for billions, is one of the most resource-hungry crops on the planet—but scientists may have found a way to change that. By applying nanoscale selenium directly to rice plants, researchers dramatically improved nitrogen efficiency, boosted yields, and made grains more nutritious while reducing fertilizer use and cutting...
Scientists crack the explosive secret of how diamonds reach the surface
Diamonds hitch a ride to the surface through explosive kimberlite eruptions, powered by volatile-rich magmas. New simulations show that carbon dioxide and water are the secret ingredients that make these eruptions possible.
Diamonds reveal hidden chemistry deep inside Earth
South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts infiltrated reduced rocks, trapping both the cause and effect of diamond formation. These reactions help explain volatile-rich magmas like kimberlites, linking mantle...
Dogs can tell how toys work without any training
Gifted dogs can categorize toys by function, not just appearance. In playful at-home tests, they linked labels like “fetch” and “pull” to toys—even ones they’d never seen before. The findings hint that dogs form mental concepts of objects, much like humans, pointing to deeper cognitive abilities.
Fish love songs recorded for 12 years reveal a surprising shift
By recording grouper grunts for 12 years, scientists discovered major shifts in how red hind spawn and compete. Courtship calls once dominated, but territorial sounds have surged, suggesting changes in population structure. Machine learning helped decode the patterns quickly, offering a groundbreaking way to monitor and conserve reef fish.
Breaking Barriers in the Ice
For years, managing personal hygiene, particularly menstruation and toileting, in the extreme Antarctic environment was often a solitary and unspoken challenge, especially for women and non-binary individuals.
