Phys.org / Rodent eradication sparks insect boom on Lord Howe Island
The removal of invasive rodents from Lord Howe Island has triggered a rebound of invertebrate life, with researchers from the University of Sydney and collaborators documenting sharp increases in the abundance of insects ...
Phys.org / Controlled experiments reveal how nuclear fallout particles form
In less than a millionth of a second after a nuclear detonation or a severe nuclear reactor accident, an enormous burst of energy heats the surrounding air and materials. Everything in the vicinity is vaporized into a hot, ...
Tech Xplore / Could sodium replace lithium as the dominant ingredient in batteries?
The world we live in today runs on batteries. But the lithium ion batteries that dominate the market are expensive and environmentally demanding to extract. The raw materials for lithium ion batteries are scarce and concentrated ...
Phys.org / Why restoring soil health is a win-win for farmers and the environment
More than half of Europe's soils are degraded. Researchers are showing that restoring soil through better farming makes both ecological and financial sense.
Phys.org / Tropical cyclones now release ocean carbon, but warming could flip role by 2035
The ocean is an important carbon sink that absorbs 20–30% of the total anthropogenic CO2 emissions in the industrial era (1.0–3.0 Pg annually, 1 Pg = 1015 g). Tropical cyclones are among the most devastating weather systems ...
Phys.org / Rethinking hysteresis—a thermodynamic framework for history-dependent solids
Many solid materials "remember" their past. A piece of metal may respond differently after being stretched, heated, or cooled, and memory materials rely precisely on this kind of history-dependent behavior. This phenomenon, ...
Medical Xpress / Ebola outbreak in the DRC: Four reasons it will be hard to contain

The inaugural Enhanced Games are underway in Las Vegas and are set to be a unique spectacle that promotes drug-induced "enhancement." The International Olympic Committee has condemned the event as a way to "destroy any concept ...
Phys.org / Astronomers may have discovered the tiniest odd radio circle
Astronomers have identified a possible new member of one of astronomy's strangest classes of objects: Odd radio circles (ORCs), enormous ring-like structures visible only at radio wavelengths. The newly discovered source, ...
Medical Xpress / Chronic liver disease in Europe: A preventable crisis going undetected
Europe is facing a growing chronic liver disease threat, according to a new series published in The Lancet Regional Health—Europe, that engaged more than 75 co-authors from 30 countries and was led by the Barcelona Institute ...
Science X / A whale meets itself at last: Belugas may have crossed a cognition line to join an elite group of animals
For humans, recognizing our reflection comes naturally, and we barely give it a second thought. Called mirror self-recognition (MSR), it is widely considered a sign of self-awareness and cognitive development. In the animal ...
