Evolution may explain 'Runner's high,' study says
(HealthDay) -- The pleasurable feeling known as "runner's high" that's triggered by aerobic exercise may have played a role in the evolution of humans' ability to run long distances, a new study suggests.
Climate scientists discover new weak point of the Antarctic ice sheet
The Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet. These predictions ...
Space weather expert has ominous forecast
A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt.
Black hole caught red-handed in a stellar homicide
(Phys.org) -- Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close.
New research suggests initial mass function for galaxies not universal
Tiny 'spherules' reveal details about Earth's asteroid impacts
(Phys.org) -- Researchers are learning details about asteroid impacts going back to the Earth's early history by using a new method for extracting precise information from tiny "spherules" embedded in layers ...
Study finds warm ocean currents cause majority of ice loss from Antarctica
Reporting this week in the journal Nature, an international team of scientists led by British Antarctic Survey (BAS) has established that warm ocean currents are the dominant cause of recent ice loss from A ...
Research finds autumn advantage for invasive plants in Eastern United States
Much like the fabled tortoise and the hare, the competition between native and invasive plants growing in deciduous forests in the Eastern United States is all about how the plants cross the finish line in autumn.
Splatters of molten rock signal period of intense asteroid impacts on Earth
New research reveals that the Archean era a formative time for early life from 3.8 billion years ago to 2.5 billion years ago experienced far more major asteroid impacts than had been previously ...
Physicists benchmark quantum simulator with hundreds of qubits
Physicists at the National Institute of Standards and Technology have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits) -- 10 times more than previous devices. ...
Genetic similarity promotes cooperation
In a dog-eat-dog world of ruthless competition and 'survival of the fittest,' new research from the University of Leicester reveals that individuals are genetically programmed to work together and cooperate ...
Long predicted but never observed: A new kind of quantum junction
A new type of quantum bit called a "phase-slip qubit", devised by researchers at the RIKEN Advanced Science Institute and their collaborators, has enabled the world's first-ever experimental demonstration ...
Great Unconformity: Evidence for a geologic trigger of the Cambrian explosion
(Phys.org) -- The oceans teemed with life 600 million years ago, but the simple, soft-bodied creatures would have been hardly recognizable as the ancestors of nearly all animals on Earth today.
