Phys.org / Electrically tunable spin polarization in graphene opens path toward low-power spintronic devices
Researchers at the National Graphene Institute, in collaboration with the National University of Singapore, have shown that the magnetic behavior of electrons in graphene can be precisely controlled using electricity, revealing ...
Phys.org / World's highest-consuming 10% cause up to $5.7 trillion a year in environmental damage, study finds
The environmental damage caused by the world's highest-consuming 10% of people is worth $1.7 trillion to $5.7 trillion a year. At the central and upper estimates, this is several times more than the international community ...
Phys.org / Long gamma-ray bursts may trace collapsing stars rather than neutron-star mergers
Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few seconds than the sun emits in 10 billion years. Los Alamos National Laboratory scientists, having discovered ...
Phys.org / Energetic neutral atoms may help map Uranus's odd magnetic environment
Sending a spacecraft to the underexplored planet Uranus is at the top of many planetary scientists' wish lists. But which spacecraft-mounted instruments would be most useful for answering questions about the mysterious ice ...
Phys.org / Mystery of 17th century shipwreck holding 400 gold coins finally solved after 30 years
The identity of a centuries-old shipwreck discovered off the south coast of England, holding 400 gold coins, has finally been identified as the Dutch trading ship "Dom van Keulen," which left Morocco for the Netherlands in ...
Phys.org / Climate change is now causing more local extinction in temperate regions than the tropics, study shows
Imagine returning to a favorite hiking trail 15 years after your first visit and discovering that many of the plants and animals that once lived there are gone. While these species may still exist elsewhere, these disappearances—known ...
Phys.org / Circular polarization could cut laser backscatter in fusion experiments
Experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the ...
Phys.org / Orangutans eat medicinal plants in patterns that suggest self-medication
Orangutans seek out plants with antimicrobial, anti-inflammatory and wound-healing properties, new research shows. Based on 20 years of observations of orangutans in Indonesian Borneo, scientists assessed how often the animals ...
Phys.org / Suburban street design has driven emissions since WWII, study suggests
Half of all Americans live in the suburbs. For decades, planners and policymakers have blamed suburban sprawl's environmental and social costs on one thing: distance. The farther people live from city centers, the more they ...
Phys.org / Asteroid Donaldjohanson wobbles as it rotates, Lucy flyby reveals
Southwest Research Institute (SwRI) scientists studying the inner main-belt asteroid Donaldjohanson have found that its rotation wobbles. Rather than rolling through space in a steady pattern, Donaldjohanson turns on two ...
Phys.org / Hidden fungus inside desert moss could rewrite 470-million-year story of how plants moved onto land
Mosses are survivors. They can dry into what looks like green dust, only to spring back to life minutes after rain. They can grow on rocks, in deserts, and there's talk of using them to terraform Mars someday. According to ...
Phys.org / Fermi mission uncovers possible sibling supernova remnants
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star's detonation sent its binary companion hurtling ...
