Orders for nuclear radiation detectors have surged on domestic e-commerce platforms, with many stores claiming to have sold out, the Global Times learned from industry insiders. Concerns have mounted following the news of Japan's dumping of nuclear-contaminated wastewater into the sea. Several online vendors reached by the Global Times on Monday said that their products […]
Beyond the small mining town of Newman in Western Australia lie the first fairy circles scientists have described outside of Africa. These patches of bare soil dot outback grasslands in almost regular polka-dot patterns, just like the puzzling circle landscapes known from Namibia, says ecologist Stephan Getzin of the Helmholtz Center for Environmental Research-UFZ in […]
Family ties last 430 million years — at least for one newly discovered arthropod species. Researchers discovered the fossilized remains of Aquilonifer spinosus encased in carbonate from a formation called the Herefordshire Lagerstätte in England. Shields covered the 9.5-millimeter arthropod from head to tail, and long spines protruded from its armor. But that’s not all: […]
A DNA-damaging protein in typhoid bacteria might keep infected animals alive and provide a safe haven for the microbes. Typhoid toxin, a protein produced by the typhoid fever-causing bacterium Salmonella enterica Typhi, tears DNA molecules apart. But the protein actually prolonged survival and reduced gut inflammation in mice infected with S. enterica, an international team […]
Physicists may soon know if a potential new subatomic particle is something beyond their wildest dreams — or if it exists at all. Hints of the new particle emerged last December at the Large Hadron Collider. Theorists have churned out hundreds of papers attempting to explain the existence of the particle —assuming it’s not a […]
Good gut bacteria might not help people with Crohn’s disease. Protective microbial messages go unread in mice and in human immune cells with certain defective genes, researchers report online May 5 in Science. The findings are the first to tie together the roles of genes and beneficial microbes in the inflammatory bowel disease, says biologist […]
Sure, mosquitoes spread Zika virus. Scientists have already identified the yellow fever mosquito (Aedes aegypti) as a major spreader in the Americas of Zika and its risk of birth defects and possible paralysis. But Ae. aegypti may not be the only culprit. Recent evidence raises concerns that a relative, the Asian tiger mosquito (Ae. albopictus), […]
In at least one part of Stone Age Europe, Neandertals were lords of the rings. Humankind’s close evolutionary cousins built large, circular structures out of stalagmites in a French cave around 176,500 years ago, researchers say. Neandertal groups explored the cave’s dark recesses, where they assembled stalagmite pieces into complex configurations, archaeologist Jacques Jaubert of […]
In a feat that demonstrates the feasibility of using satellites to transmit uncrackable quantum messages, scientists have measured the quantum properties of photons sent to space and back again. Physicists beamed the blips of light up to a satellite that reflected them back to Earth. Upon the photons’ return, the team, led by Paolo Villoresi […]
The world’s current game plan to combat climate change will miss the mark. Crunching the numbers on 187 nations’ climate action proposals announced in advance of the December 2015 Paris Agreement, researchers estimate that the efforts will limit global warming to 2.6 to 3.1 degrees Celsius above preindustrial levels. That’s far above the goal agreed […]
