Stephanie Kirsop didn't believe her son when he phoned to say a crocodile was lurking in a creek near their home.
Phys.org / Warming El Nino may return later this year: UN
The warming El Niño weather phenomenon could return later this year as its cooling opposite La Niña fades away, the United Nations said Tuesday.
Tech Xplore / Second-hand phones surf rising green consumer wave
The secondhand market for smartphones has surged in recent years, borne up by lower prices as well as interest in eco-friendly consumption even as some still fear buying a dud.
Tech Xplore / China's overstretched health care looks to AI boom
Throughout her first pregnancy, Wang Yifan had lots of questions, which she usually put to renowned obstetrician Duan Tao—or rather, an AI clone of the top Shanghai-based doctor.
Phys.org / Tiny Purgatorius fossils in Denver Basin hint at early primate spread southward
New minuscule fossils of Purgatorius, the earliest-known relative of all primates—including humans—have been unearthed in a more southern region of North America than ever before, and the breakthrough is providing paleontologists ...
Phys.org / Modern twist on wildfire management methods has a bonus feature that protects water supplies
Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires ...
Phys.org / Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating ...
Phys.org / Quantum dynamics show 'memory' depends on whether states or observables evolve
An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while retaining memory from ...
Phys.org / NASA's MAVEN detects first evidence of lightning-like activity on Mars
While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused ...
Phys.org / Dense, dark forests in Europe are a modern phenomenon
For over 20 million years, the landscape of Europe has been a tree-rich mosaic of grasslands, scrubs and more or less open woodlands with an abundance of wildflowers. This is the conclusion of a new and comprehensive study ...
Phys.org / Physicists discover long-predicted 'clock magnetism' in an atomically thin crystal
Strange things happen to materials when you peel them down, layer by layer, from thick chunks all the way to sheets just an atom thick. Reporting in the journal Nature Materials, a team led by physicists at The University ...
Tech Xplore / AI often escalates to nuclear action in war games
There are some things perhaps we might not want artificial intelligence to handle, at least for the time being. When leading chatbots were put through war-game simulations, they opted for nuclear signaling or escalation in ...
