Why Pickle Brine On Icy Roads Could Be Smarter Than Salt Rock salt is one of the most effective substances for deicing roads when winter weather strikes. But while it makes roads safer, tons of salt end up in lakes, rivers and marshes where it poses dangers to aquatic life and the potability of water sources. In some cases, it’s been building up, layer by layer, since the 1930s. Currently, the U.S. dumps about 15 million tons each year. It doesn't

But one of the greatest obstacles on this road is stability: to be commercially viable, perovskite solar cells must also be able to maintain their efficiency over tim

Immune cells play key role in early breast cancer metastasis even before a tumor develops (New York, NY – January 2, 2018) –Mount Sinai researchers have discovered that normal immune cells called macrophages, which reside in healthy breast tissue surrounding milk ducts, play a major role in helping early breast cancer cells leave the breast for other parts of the body, potentially creating metastasis before a tumor has even developed, according to a study published in Nature Communic

86 stars get official names In December, astronomers and space enthusiasts received an early present: 86 newly official star names. Such designations are often derived from Arabic, Greek or Latin origins. But the new monikers also draw inspiration from ancient mythologies and historical star names from indigenous cultures around the world, including in China, Australia and southern Africa. The star names were officially rec

My Year on "Mars" The wind sweeps quietly across the barren, dry landscape. There is not a shrub in sight, not a tree, not a single blade of grass that the wind might disturb. Only barren grayish-red rocks. The wind never touched us as we peered out of our only window, which was more of a porthole than a real window. We did hear it though as it swept across our white dome perched on the slope of the volcano.

Sundhedsminister om SSI's manglende tilsyn: »Ikke godt nok og stærkt kritisabelt« Sundhedsminister Ellen Trane Nørby (V) går nu ind i sagen om Statens Serum Institut (SSI), som har forsømt at føre tilsyn med, om danskeres person- og sundhedsdata er blevet behandlet korrekt. Ministeren kræver, at SSI udarbejder en redegørelse for, hvordan de vil håndtere danskernes data lovligt i fremtiden. Reaktionen kommer efter, at Version2 tidligere i dag kunne afsløre, at SSI ikke har ført

Spansk entreprenør afkræves 625 mio. kr for fejl i Niels Bohr Bygningen Et krav om at betale 625 millioner kroner var formentlig ikke den julegave, som den spanske entreprenørkoncern Inabensa havde håbet på. Det var ikke desto mindre det, virksomheden fik fra Bygningsstyrelsen. Det fremgår af en pressemeddelelse fra styrelsen. Inabensa vandt i sin tid opgaven med at installere VVS, køl, varme, CTS, kloak, konstruktioner, sprinkler og gas i Niels Bohr Bygningen – et g

Streams can be ‘sensors’ for sustainable watersheds Streams can be diagnostic “sensors” for a watershed’s sensitivity to changes in land use practices, such as the long-term use of fertilizers, according a new study. “The manipulation of phosphorous and nitrogen in the landscape is one of the greatest threats to the fate of humanity and the rest of life on this planet…” Using streams as sensors—specifically, near the headwaters—can allow scientist

How Snakes Lost Their Legs A Chinese riddle invites on to guess the identity of runners without a leg, swimmers without a flipper, gliders without a wing. The answer, of course, is snakes. Today more than 3,000 species share a long, limbless body that can negotiate land, water and even the air between trees. Their ancient ancestors, however, had limbs of various shapes. How, scientists have wondered, did snakes lose their

These compounds starve blood cancer to death Newly synthesized compounds can starve multiple myeloma—a rare form of blood cancer—to death, according to a series of studies using patient samples. The new compounds offer “a new strategy for attacking multiple myeloma…” Tumor cells, including those of the largely fatal plasma cell malignancy multiple myeloma, thrive on glucose. In this cancer, the tumor co-opts the GLUT4 protein, a vital gluco

Navigating the Uncanny Valley of Food A quarter century ago, Steven Spielberg created velociraptors that were viscerally compelling enough to toe-claw tap dance straight into our nightmares. Last year, the VFX team behind Rogue One gave us a posthumously CGI-reanimated Peter Cushing as Grand Moff Tarkin , and that inspired a different and unintended kind of unease.

Forskere: Fortællingen om Fimbulvinteren holder stik Det er ikke kun i den populære tv-serie Game of Thrones, at årstidernes længde varierer. Ifølge den nordiske mytologi varer Fimbulvinteren tre år, og varsler begyndelsen på Ragnarok – Jordens undergang, hvor alt liv dør. Men mytologien har formentlig rod i virkeligheden. De seneste år har forskere i Norge og Sverige nemlig fundet stadig flere spor, der tyder på, at der indtraf en klimakatastrofe

A sinking, melting ancient tectonic plate may fuel Yellowstone’s supervolcano The driving force behind Yellowstone’s long and explosive volcanic history may not be as deep as once thought. A new study suggests that instead of a plume of hot mantle that extends down to Earth’s core, the real culprit is a subducting tectonic plate that began sinking beneath North America hundreds of millions of years ago. Computer simulations show that movement of broken-up remnants of the a
