Phys.org / Continued monitoring of sunken Soviet submarine shows ongoing radioactive leakage, but little impact
In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy ...
Phys.org / Europe's Late Neanderthals descended from a single population, DNA analysis suggests
A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance ...
Phys.org / Are humans naturally violent? New research challenges long-held assumptions
New research from the University of Lincoln, UK, is challenging a common assumption about the evolutionary origins of human violence, suggesting that everyday aggression does not inevitably lead to lethal conflict. The study, ...
Tech Xplore / New bifacial solar cells yield efficiencies above 32%
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries worldwide. Over the past few years, energy engineers have been exploring alternative designs that could further boost ...
Phys.org / All 5 fundamental units of life's genetic code were just discovered in an asteroid sample
A new study reveals all five fundamental nucleobases—the molecular "letters" of life—have been detected in samples from the asteroid Ryugu.
Phys.org / What 'Project Hail Mary' gets right—and wrong—about astrophysics
"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning ...
Phys.org / Shift in key cosmic inflation measurement could be a statistical artifact
For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big ...
Phys.org / Quantum computers could have a fundamental limit after all
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University ...
Phys.org / The 'private solution trap': Why richer countries may favor adaptation over public solutions, and who pays
A new study, led by the University of Nottingham and conducted by a team of 72 economists and psychologists across the world, has identified a potential "private solution trap" in problems requiring international cooperation ...
Phys.org / Moons orbiting wandering exoplanets could be habitable—with one catch
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
Phys.org / Superconducting quantum processor performs well with significantly less wiring
Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum ...
Phys.org / How birds send heat into space measured for the first time—a hidden reflectance of feathers
As human-caused climate change continues to raise temperatures across the globe, understanding how birds regulate their temperature is vital for their conservation. But how much heat birds emit—an invisible spectrum of ...
