Phys.org / Screens dominate the dinner table, with 77.6% of parents using devices
Food has always had a unique way of bringing people together. It becomes especially evident during family mealtimes, when children and adults gather around the table to share more than just a meal. They share stories, catch ...
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 / 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 / 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 / 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 / Mars life search gets boost as rover test distinguishes mirrored biosignature molecules
Billions of years ago, environmental conditions on Mars were significantly more hospitable than they are today. Our neighboring planet was likely warm, humid and surrounded by a dense atmosphere. Whether simple microorganisms ...
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 / Alpha Magnetic Spectrometer reveals four cosmic ray classes across 20 elements, defying current models
Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life. In fact, the star may ...
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 / 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 ...
Phys.org / Laser pulses set layered metals vibrating 1 trillion times per second, revealing electron-driven motion
How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely ...
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 ...
