Phys.org / A new class of strange one-dimensional particles
Physicists have long categorized every elementary particle in our three-dimensional universe as being either a boson or a fermion—the former category mostly capturing force carriers like photons, the latter including the ...
Phys.org / Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way
Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...
Phys.org / Ultra-thin metasurface chip turns invisible infrared light into steerable visible beams
The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science Research Center at the CUNY ...
Phys.org / Stacked graphene sandwich reveals switchable memory without traditional ferroelectrics
A research team led by Professor Youngwook Kim from the Department of Physics and Chemistry, DGIST, in collaboration with the research team of Professor Gil Young Cho at KAIST, have discovered a new memory principle that ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
Phys.org / Two huge hot blobs of rock influence Earth's magnetic field, study reveals
Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 km. Consequently, little ...
Phys.org / Reproduction in space, an environment hostile to human biology
As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now "urgently practical," according ...
Phys.org / Ozone-depleting CFCs detected in historical measurements—20 years earlier than previously known
An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier than previously known. ...
Phys.org / One-of-a-kind 'plasma tunnel' recreates extreme conditions spacecraft face upon reentry
Picture a spacecraft returning to Earth after a long journey. The vehicle slams into the planet's atmosphere at roughly 17,000 miles per hour. A shockwave erupts. Molecules in the air are ripped apart, forming a plasma—a ...
Phys.org / Political division in the US surged from 2008 onward, study suggests
Divisions within the US population on social and political issues have increased by 64% since 1988, with almost all this coming after 2008, according to a study tracking polarization from the end of the Reagan era to the ...
Phys.org / Ancient American pronghorns were built for speed
The fastest land animal in North America is the American pronghorn, and previously, researchers thought it evolved its speed because of pressure from the now-extinct American cheetah. But recently, that theory has come under ...
Phys.org / High-tech scans of an enigmatic 400-million-year-old lungfish reveal new details
New pieces have been added to the puzzle of the evolution of some of the oldest fish that lived on Earth more than 400 million years ago. In two separate studies, experts in Australia and China have found new clues about ...
