Howler monkeys may owe their color vision to leaf hue

BOSTON — A taste for reddish young leaves might have pushed howler monkeys toward full-spectrum color vision. The ability to tell red from green could have helped howlers pick out the more nutritious, younger leaves, researchers reported February 19 at the annual meeting of the American Association for the Advancement of Science. That’s a skill […]

Certain birth defects are on the rise since Zika arrived in the U.S.

Certain birth defects were 20 times more prevalent in babies born to Zika virus–infected mothers in the U.S. in 2016 than they were before the virus cropped up in the United States, a CDC study suggests. The finding strengthens the evidence that a mother’s Zika infection during pregnancy raises her baby’s risk of microcephaly and […]

In new Cassini portraits, Saturn’s moon Pan looks like pasta

Saturn serves up the closest thing to space pasta, the latest round of images from NASA’s Cassini probe, released March 9, show. On March 7, the spacecraft snapped a series of portraits of Pan, Saturn’s small moon that orbits within a 325-kilometer gap in one of the planet’s rings. Taken at a distance of 24,572 […]

Large Hadron Collider experiment nabs five new particles

Physicists have snagged a bounty of five new particles in one go. Members of the LHCb experiment, located at the Large Hadron Collider near Geneva, reported the prolific particle procurement in a paper posted online March 14 at arXiv.org. The five particles are each composed of three quarks — a class of particle that makes […]

Ancient Romans may have been cozier with Huns than they let on

Nomadic warriors and herders known as the Huns are described in historical accounts as having instigated the fifth century fall of the Roman Empire under Attila’s leadership. But the invaders weren’t always so fierce. Sometimes they shared rather than fought with the Romans, new evidence suggests. Huns and farmers living around the Roman Empire’s eastern […]

‘Specimens’ goes behind the scenes of Chicago’s Field Museum

Most visitors to a large natural history museum don’t know it, but they are only scratching the surface of the museum’s holdings, even if they check out every exhibition. Most of the scientific treasures are tucked away in collection rooms filled with millions of specimens, which scientists use in their research. The Field Museum in […]

Common virus may be celiac disease culprit

A common and usually harmless virus may trigger celiac disease. Infection with the suspected culprit, a reovirus, could cause the immune system to react to gluten as if it was a dangerous pathogen instead of a harmless food protein, an international team of researchers reports April 7 in Science. In a study in mice, the […]

Gene knockouts in people provide drug safety, effectiveness clues

Some Pakistani people are real knockouts, a new DNA study finds. Knockouts in this sense doesn’t refer to boxing or a stunning appearance, but to natural mutations that inactivate, or “knock out” certain genes. The study suggests that human knockouts could prove valuable evidence for understanding how genes work and for developing drugs. Among 10,503 […]

The Arctic is a final garbage dump for ocean plastic

The Arctic Ocean is a final resting place for plastic debris dumped into the North Atlantic Ocean, new research suggests. A 2013 circumpolar expedition discovered hundreds of tons of plastic debris, from fishing lines to plastic films, ecologist Andrés Cózar of the University of Cádiz in Spain and colleagues report April 19 in Science Advances. […]

We went to the March for Science in D.C. Here’s what happened

The March for Science, Washington, D.C. — On April 22, 2017 — Earth Day — thousands of scientists, science advocates and general enthusiasts rallied on the grounds of the Washington Monument in Washington, D.C., at the first-ever March for Science. The organizers estimate that over 600 sister marches also occurred around the world. The march […]
