Phys.org / Rule-breaking supermassive black hole discovered in the early universe
An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing supermassive black holes known ...
Phys.org / Human penis size influences female attraction and male assessment of rivals, study suggests
Men assess potential rivals that have a larger penis as more of a threat, both physically and sexually, according to a study by Upama Aich at the University of Western Australia and colleagues, published in PLOS Biology.
Phys.org / Rethinking where life could exist beyond Earth
Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that this ring is too strict: ...
Phys.org / Stress-reduction molecule has potential to treat aging and metabolic disorders
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and treatment for metabolic disorders and aging.
Phys.org / Space station crew credits ultrasound machine for handling in-orbit health crisis
The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in "super handy" during the medical crisis.
Phys.org / Molecular surgery: 'Deleting' a single atom from a molecule
Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This process, called skeletal editing, can dramatically speed up drug discovery or be applied for upcycling ...
Phys.org / Aging zoo animals threaten long-term species conservation goals
Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. ...
Phys.org / ATLAS confirms collective nature of quark soup's radial expansion
Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world's most powerful particle collider, located at CERN, the European Organization for Nuclear Research—have new evidence that ...
Phys.org / Study challenges long-held theory that language is built on grammar trees
Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-spoken or -written sentences," said Morten H. Christiansen, the ...
Phys.org / Arctic cloud and ice formation affected by Russian river runoff as region studied for first time
Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
Phys.org / A new optical centrifuge is helping physicists probe the mysteries of superfluids
Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.
Phys.org / Beneath Antarctica's largest ice shelf, a hidden ocean is revealing its secrets
Beneath Antarctica's Ross Ice Shelf lies one of the least measured oceans on Earth—a vast, dark cavity roughly twice the volume of the North Sea.
