    How Asian nomadic herders built new Bronze Age cultures

    Nomadic herders living on western Asia’s hilly grasslands made a couple of big moves east and west around 5,000 years ago. These were not typical, back-and-forth treks from one seasonal grazing spot to another. These people blazed new trails.

    A technological revolution had transformed travel for ancient herders around that time. Of course they couldn’t make online hotel reservations....

    Simulating the universe using Einstein’s theory of gravity may solve cosmic puzzles

    If the universe were a soup, it would be more of a chunky minestrone than a silky-smooth tomato bisque.

    Sprinkled with matter that clumps together due to the insatiable pull of gravity, the universe is a network of dense galaxy clusters and filaments — the hearty beans and vegetables of the cosmic stew. Meanwhile, relatively desolate pockets of the cosmos, known as voids, make up a thin...

    A universal flu shot may be nearing reality

    One of the planet’s deadliest viruses makes an annual pass through the United States with little fanfare. It rarely generates flashy headlines or news footage of health workers in hazmat suits. There’s no sudden panic when a sick person shows up coughing and feverish in an emergency room. Yet before next spring, this season’s lethal germ will probably have infected millions of Americans,...

    The list of diseases linked to air pollution is growing

    To the residents of Donora, Pa., a mill town in a crook of the Monongahela River, the daily haze from nearby zinc and steel plants was the price of keeping their families fed. But on October 27, 1948, the city awoke to an unusually sooty sky, even for Donora. The next day, the high school quarterbacks couldn’t see their teammates well enough to complete a single pass.

    The town was...

    Here are the paths of the next 15 total solar eclipses

    August's total solar eclipse won’t be the last time the moon cloaks the sun’s light. From now to 2040, for example, skywatchers around the globe can witness 15 such events.  

    Their predicted paths aren’t random scribbles. Solar eclipses occur in what’s called a Saros cycle — a period that lasts about 18 years, 11 days and eight hours, and is governed by the moon’s orbit. (Lunar eclipses...

    Ancient DNA offers clues to the Canaanites’ fate

    DNA is setting the record straight on ancient Canaanites.

    For the first time, scientists have deciphered the complete genetic instruction manuals of Canaanites. By comparing five Canaanite genomes with those of other ancient and modern populations, the researchers identified the Canaanites’ ancestors and discovered their descendants, modern Lebanese people.

    The results, reported...

    GM moth trial gets a green light from USDA

    Cabbage-chomping moths genetically modified to be real lady-killers may soon take flight in upstate New York. On July 6, the U.S. Department of Agriculture OK’d a small open-air trial of GM diamondback moths (Plutella xylostella), which the agency says do not pose a threat to human or environmental health.

    These male moths carry a gene that kills female offspring before they mature....

    DNA evidence is rewriting domestication origin stories

    One lab full of rats looks pretty much the same as another. But visiting a lab in Siberia, geneticist Alex Cagan can distinguish rats bred to be tame from those bred to be aggressive as soon as he opens the lab door.

    “It’s a completely different response immediately,” he says. All of the tame rats “come to the front of the cage very inquisitively.” The aggressive rats scurry to the backs...

    Primitive whales had mediocre hearing

    Early on, whale hearing may have been ho-hum.

    Unlike today’s whales that specialize in making  — and hearing — very high- or low-pitched sounds, early whales’ ears probably picked up noises somewhere in the middle, paleontologists Mickaël Mourlam and Maeva Orliac report June 8 in Current Biology.

    Looking at CT scans of ancient whale ear bones allowed the researchers, from the...
