Traces of antidepressants and painkillers found in crustaceans
Researchers from SINTEF, the Norwegian Polar Institute and the University Centre in Svalbard have collected samples from Arctic crustaceans close to the settlement of Ny-Ålesund on the west coast of Spitsbergen. During the spring and summer, they di.....»»
20% of grocery store milk has traces of bird flu, suggesting wider outbreak
The milk is still considered safe, but disease experts are alarmed by the prevalence. Enlarge (credit: Getty | Jeffrey Greenberg) The Food and Drug Administration reported late Thursday that about 20 percent of retail mi.....»»
Scientists confine, study Chinook at restored Snoqualmie River habitat
In newly restored river channels on the Snoqualmie, baby Chinook salmon are confined in 19 enclosures about the size of large suitcases as they munch on little crustaceans and invertebrate insects floating or swimming by......»»
Signs of "spider" phenomenon on Mars
ESA's Mars Express has snapped the telltale traces of "spiders" scattered across the southern polar region of Mars......»»
Traces of DNA in the stomachs of predatory snails provide new insights into the ecology of placozoans
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or fl.....»»
New research traces the fates of stars living near the Milky Way"s central black hole
Despite their ancient ages, some stars orbiting the Milky Way's central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these stars look young for a much.....»»
Preventive drone attacks based on digital traces are a gray area under international law
Identifying terrorists by analyzing their online activities is an approach that is sometimes at odds with international law, especially if the outcome is death. A study has documented this problematic legal and ethical issue......»»
Thousands of Asus routers taken over by malware to form new proxy service
Outdated Asus routers are being assimilated into a malicious botnet used by hackers to hide their traces.....»»
Giving particle detectors a boost: New device acts like a superconductivity switch
In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors in these facilities use s.....»»
Archaeologists unearth abandoned townsite at Washington on The Brazos
A short walk from the banks of the Brazos River in Washington County, members of a small crew dressed in sun hats and gardening gloves push buckets of mud through metal sieves, picking out nails, bits of glass and ceramic, and other traces of a log c.....»»
Earthquake research traces the pace of an approaching "seismic dragon king"
The 'Dragon King' theory was proposed based on the physics of complexity. According to this theory, 'Dragon King' events deviate from the power law distribution as a statistical outlier and, noticeably, have predictability......»»
Earth as a test object to evaluate the planned LIFE space mission
Physicists at ETH Zurich and the University of Zurich wanted to know whether the planned LIFE space mission could really detect traces of life on other planets. Yes, it can, say the researchers, with the help of observations of our own planet......»»
Study details toxic elements found in stranded whales, dolphins over 15 years
Whales and dolphins get their nutrients and essential elements through their diet. While eating fish, squid, octopus, crustaceans, and other marine mammals, they are also exposed to heavy metal contaminants......»»
Mercury levels in tuna remain nearly unchanged since 1971, study says
Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environ.....»»
Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night
In the dark and cold of the months-long polar night, food resources are limited. Some groups of marine organisms in the polar regions overcome this challenge by going into a metabolic resting state in winter, surviving on reserves accumulated during.....»»
Traces of Stone Age hunter-gatherers discovered in the Baltic Sea
In autumn 2021, geologists discovered an unusual row of stones, almost 1 km long, at the bottom of Mecklenburg Bight. The site is located around 10 kilometers off Rerik at a 21-meter water depth. The approximately 1,500 stones are aligned so regularl.....»»
Hubble traces "string of pearls" star clusters in galaxy collisions
Contrary to what you might think, galaxy collisions do not destroy stars. In fact, the rough-and-tumble dynamics trigger new generations of stars and presumably accompanying planets......»»
Studying lake deposits in Idaho could give scientists insight into ancient traces of life on Mars
Does life exist elsewhere in the universe? If so, how do scientists search for and identify it? Finding life beyond Earth is extremely difficult, partly because other planets are so far away and partly because we are not sure what to look for......»»
Hermit crabs find new homes in plastic waste: Shell shortage or clever choice?
The crustaceans are making the most of what they find on the seafloor. Enlarge / Scientists have found that hermit crabs are increasingly using plastic and other litter as makeshift shell homes. (credit: Luis Diaz Devesa/Getty).....»»
Study traces the roots of longstanding cultural interactions across the Tibetan Plateau to prehistoric times
The 1 million-square-mile Tibetan Plateau—often called the "roof of the world"—is the highest landmass in the world, averaging 14,000 feet in altitude. Despite the extreme environment, humans have been permanent inhabitants there since prehistori.....»»
On tropical coasts, hermit crabs are now making their homes in plastic waste
Terrestrial hermit crabs are soft-bodied crustaceans that live near water in the world's tropical areas. Without any natural protection of their own, these crabs normally find shelter in discarded mollusk shells. But a number of terrestrial hermit cr.....»»
