Physicists “trick” photons into behaving like electrons using a “synthetic” magnetic field

Stressing a metasurface with a honeycomb generates an artificial magnetic field for light, which can be adjusted by embedding the metasurface in a waveguide cavity. Credit: University of Exeter Scientists have found an elegant way to manipulate light with the help of Lorentz’s “synthetic” force, which in nature is responsible for many fascinating phenomena, including Aurora Borealis. A team of …

Antarctic glaciers are growing unstable above and below water

This study, published today in Notices of the National Academy of Sciences, concludes that understanding how the ice field breaks as it moves through the rock is vital to understanding when this collapse can occur. In addition to identifying weaknesses in the glacier, Lhermitte and colleagues created a computer model to predict how such cracking and distortion could affect other …

Non-native seeds found in shipping containers pose significant threats

With backpack vacuums, the research team began looking for non-native plant seeds on the air intake grilles in refrigerated containers – and found thousands of them. Credit: Rima Lucardi, USFS Seeds that are carried in the air can hitchhike in unusual places – such as the air intake grille of a refrigerated container. A team of researchers from the USDA …

The Arctic we know is disappearing due to climate change

The remnants of sea ice off Greenland. Photo: Joe Riddle (Getty images) This year in the Arctic quite strange things happened, with historical levels of ice melting,, absurdly high temperatures, and Forest fires in an area that should be the definition of cold. A new study by scientists from the National Center for Atmospheric Research (NCAR) shows that we should …

What did the ancients eat? Now scientists can tell us.

What is cooking?Photo: headlight (Getty Images) The old pot never gets really clean, no matter how much you rub. People in the old days before antibacterial soap probably already understood it, but they just left their pots for archaeologists to find. They didn’t leave the cookbooks, either because they didn’t have them, or because the books fell apart over the …
