‘The spark has ignited.’ Latin American scientists intensify fight against sexual harassment
Feb. 20, 2020
Universities across Latin America are struggling to protect women within cultures that have long tolerated, and even celebrated, male privilege and a set of attitudes known as machismo. Such masculine demography has helped promote a sometimes toxic atmosphere for women in academia—including faculty and students in the sciences—according to dozens of researchers from across Latin America who spoke with Science. But now, the tide might be turning.
Pools in the Mexican desert are a window into Earth’s early life
June 30, 2020
Deep in Mexico's Chihuahuan Desert, the turquoise-blue pools of Cuatro Ciénegas host ancient microbes and provide a "window into early Earth." But this "lost world" has been endangered since the 1970s. The intensive drainage of the precious water to grow alfalfa—a water-intensive crop—for cattle fodder is gradually drying the improbable oasis.

News about new discoveries
This pterosaur supported its giant neck with bones built like bicycle wheels
About 100 million years ago, gigantic flying reptiles with necks longer than those of giraffes cruised the skies of modern-day Morocco. Scientists think this kind of pterosaur, with its large jaw and slim neck, preyed on fish, small mammals, and even baby dinosaurs. But how their necks didn’t snap as they carried their prey has long been a mystery. Now, a new study shows the bones inside had an intricate spokelike structure that made them strong and stable, but light enough for flight.

Octopuses, like humans, sleep in two stages
Mar. 25, 2021
Do octopuses dream? Scientists haven’t cracked that mystery, but they have come a bit closer. A new study reveals that, like us, our eight-legged friends experience both an active and a quiet sleep stage. Because humans and octopuses are separated by more than 500 million years of evolution, the discovery suggests a two-stage sleep pattern evolved independently twice.
Did heavy rains trigger the eruption of the most dangerous U.S. volcano? Scientists are skeptical
Apr. 22, 2020
In May 2018, Hawaii’s Kilauea volcano let loose its largest eruption in 200 years, spewing plumes of ash high into the air, and covering hundreds of homes in lava. The eruption terrified local residents, but it gave scientists a once-in-a-lifetime opportunity to study the volcano’s explosive behavior. Now, a new study claims that extreme rainfall boosted underground pressures and was the “dominant factor” in triggering the eruption.
Body composting promises a sustainable way of death
Feb. 18, 2020
SEATTLE—Death is not environmentally friendly. Cemeteries take up about 500 square kilometers in the United States. Embalming the dead consumes millions of liters of chemicals each year. And cremation takes large amounts of natural gas, producing plentiful greenhouse emissions. So why not take a cue from consumers who recycle their food waste into soil, and do the same to our mortal remains?
How to donate a piece of your brain to science—while you’re still alive
Feb. 15, 2020
SEATTLE—Donating a piece of your brain to biomedical research has never been easier. Scientists have developed a successful live donor program, where patients undergoing brain surgery can contribute a piece of their brain that would otherwise be tossed away. The researchers—led by neuroscientist Ed Lein at the Allen Institute for Brain Science—presented their approach here yesterday at the annual meeting of AAAS, which publishes Science.
The microbes in your gut could predict whether you’re likely to die in the next 15 years
The microbes in our guts have been linked to everything from arthritis to autism. Now, scientists say they can even tell us about our future health. Two new studies find that our “microbiome”—the mix of microbes in our gut—can reveal the presence of many diseases better than our own genes can—and can even anticipate our risk of dying within the next 15 years.

Obituary of Ricardo Valderrama Fernández.
Peruvian scientist and politician Ricardo Valderrama Fernández was first in many things. In the 1970s, he was among the first anthropologists to make contact with the Kugapakori, an Indigenous group living in the Peruvian Amazon. He co-founded the first research institute for Andean studies in Cusco in 1974. And in 1977, he wrote a “revolutionary” work on Indigenous, Quechua-speaking laborers, in which—breaking with anthropological traditions of the time—their testimony took center stage.

Troubles escalate at Ecuador’s dream research university
Oct. 21, 2020
It was supposed to become Ecuador's dream research university—an international hub for science and higher education, nestled in a new campus in the mountains 2 hours north of Quito. Instead, 6-year-old Yachay Tech University has long been mired in conflicts. Now, Ecuador's economic woes and shifting politics have stirred new turmoil that threatens the university's drive for “independent” status, which would allow it to run its own affairs.

Top neuroscientist leaves Mexican university as former trainees allege sexual harassment
Mar. 17, 2020
Earlier this month, Mexico’s leading university, the National Autonomous University of Mexico (UNAM), announced that renowned neuroscientist Ranulfo Romo Trujillo would leave his position after being disciplined for an unspecified offense.
According to a 4 March press release from UNAM, Romo Trujillo voluntarily asked to be separated from his job at UNAM’s University City campus in Mexico City. Sources close to the case say he had been temporarily suspended because a female worker made a formal complaint of sexual harassment against him following an incident in January. But current and former UNAM students and staff say that reports of inappropriate behavior by Romo Trujillo had circulated for years before his departure.

Longest deep-sea animal spotted off Australian coast
Apr. 10, 2020
The deep sea is largely unexplored and marine scientists are constantly surprised by the creatures they find roaming the depths in darkness. While exploring the Ningaloo Canyons off the coast of Western Australia with the SuBastian underwater robot, a team of researchers spotted what they believe is the longest organism ever recorded: a giant siphonophore of the genus Apolemia, Newsweek reports.
Atomic bomb dating reveals true age of whale sharks
Apr. 8, 2020
Whale sharks are the largest fish in the ocean—and one of the longest lived, a new study suggests. Sharks lack otoliths—bony structures in the skull that scientists use to estimate the age of most fish—which makes it tricky to estimate their age. So researchers measured the carbon-14 isotope in the cartilaginous vertebrae of two whale sharks and correlated it to the carbon-14 patterns created by Cold War–era bomb detonations, National Geographic reports.

Unusual Arctic warming explained by overlooked greenhouse gases
Jan. 21, 2020
The same gases that caused holes in Earth’s ozone layer in the past century are responsible for the rapid warming of the Arctic as well, according to a new study published in Nature. Scientists looked at the effect of these gases in climate simulations between 1955 and 2005. They found that the gases accounted for up to half of the warming and sea-ice loss of the Arctic during that period, Nature reports.
