The Neolithic Agricultural Revolution is one of the most thoroughly-studied episodes in prehistory. But a new article shows that most explanations for it don't agree with the evidence, and offers a new interpretation.

The Neolithic Agricultural Revolution is one of the most thoroughly-studied episodes in prehistory. But a new article shows that most explanations for it don't agree with the evidence, and offers a new interpretation.
Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted.
Argonne scientists look to 3-D printing to ease separation anxiety, which paves the way to recycle more nuclear material.
The experts tell us that small, easy changes alone will not be enough to combat climate change.
Stratolaunch, the company that was founded by the late Seattle billionaire Paul Allen in 2011 to build a flying launch pad for rockets, says it's under new ownership. The transition serves as the latest sign that Jody Allen — Paul Allen's sister, who took control of his Vulcan Inc. holding company as the trustee and executor of his estate — is paring back and refocusing his many...
A new study in the Journal of the American Chemical Society explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide.
Soviet cosmonaut Alexei Leonov floated above the Earth for 12 minutes in 1965.
It was a Sunday tradition at Bethany Slavic Missionary Church. After morning services, Florin Ciuriuc joined the line of worshippers waiting to fill their jugs with gallons of free drinking water from a well on the property, a practice church leaders had encouraged.
Danish brewer Carlsberg says it is developing a paper beer bottle made from sustainably sourced wood fibers.
A vivid fresco depicting an armour-clad gladiator standing victorious as his wounded opponent stumbles gushing blood has been discovered in the ancient Roman city of Pompeii, Italy's culture ministry said Friday.
The "necklace" injuries, many caused by discarded plastic waste, are becoming more common, says the RSPCA.
Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.
For the first-time we can take a molecular-level look at one of the world's deadliest crop killers.
Population aging projections across the US show a divide between cities and rural areas, which could lead to pockets of vulnerability to climate change.
Anthropogenic noise pollution (ANP) is a globally invasive phenomenon impacting natural systems, but most research has occurred at local scales with few species. Researchers in this study investigated continental-scale breeding season associations with ANP for 322 bird species to test whether local-scale predictions related to breeding habitat, migratory behavior, body mass, and vocal traits are...
Standing amid cottonwood trees and a thicket of other vegetation, Jon Hansen looks out over a sunlight-dappled ribbon of crystal water running over a rocky bed. He's standing on a site that until recently was filled with houses and mobile homes—properties that flooded six times in 20 years when the Cedar River spilled over its banks.
Nearly 600 former Environmental Protection Agency officials have called for an investigation into whether the agency's leaders abused their authority by threatening punitive action against California.
Two weeks ago, the head of NASA seemed sick of waiting for SpaceX and Boeing Co. to finish developing the capsules that are supposed to carry U.S. astronauts to and from the International Space Station.
The company’s LauncherOne system is designed to send satellites to low-Earth orbit. Does it really have the power to send a payload to the Red Planet?
New microbial research at the University of Copenhagen suggests that 'survival of the friendliest' outweighs 'survival of the fittest' for groups of bacteria. Bacteria make space for one another and sacrifice properties if it benefits the bacterial community as a whole. The discovery is a major step towards understanding complex bacteria interactions and the development of new treatment models for...
A U.S. Naval Research Laboratory (NRL) instrument aboard NASA's Ionospheric Connection Explorer (ICON) satellite will deliver unprecedented information to help scientists investigate how both terrestrial and solar weather impact the ionosphere, the ionized region of Earth's upper atmosphere. ICON launched from Cape Canaveral, Florida, Oct. 10.
The walking speed of 45-year-olds can be used as a marker of their aging brains and bodies. The evidence was there in neurocognitive testing these individuals took at age 3 to indicate who would become the slower walkers. At 45, slower walkers have 'accelerated aging' on a 19-measure scale devised by researchers, and their lungs, teeth and immune systems tended to be in worse shape than the people...
Current testing for Lyme disease, called the standard 2-tiered approach or the STT, involves running two complex assays (ELISA and western blot) to detect antibodies against the bacterium, and requires experienced personnel in a lab, and a few hours to carry out and interpret. Biomedical engineers have developed a rapid microfluidic test that can detect Lyme disease with similar performance as the...
When asked to answer questions quickly and impulsively, people tend to respond with a socially desirable answer rather than an honest one, a set of experiments shows.
