Mars rover wraps survey of Jezero crater’s surprising volcanic floor | Science

THE WOODLANDS, TEXAS—After a year exploring the floor of Mars’s Jezero crater, where it gathered seven—soon to be eight—chalk-size rock samples for return to Earth, NASA’s Perseverance rover is set to speed toward its longstanding target at the crater’s edge: the remnants of a delta, deposited by water billions of years ago, that may contain … Read more

A network of young scientists and doctors aims to rebuild Venezuela’s devastated public health system | Science

A version of this story appeared in Science, Vol 375, Issue 6585. The reconnaissance trip in western Venezuela was going smoothly—until a gunman took aim at their windshield. It was March 2019, and two infectious disease specialists, Alberto Paniz Mondolfi and Carlos Hernandez, were driving back to their headquarters from villages in Venezuela’s disease-ridden Portuguesa … Read more

New insight into magma chambers could improve volcano models | Science

Researchers have discovered a simple and surprising control over the depth of a volcano’s magma chamber: how much water it contains. The finding is significant because water fuels the most devastating eruptions—from Vesuvius in 79 C.E. to Mount Pinatubo in 1991. The work could also help improve models that predict eruptions, which for years have … Read more

One More Pioneering Woman in Science You’ve Probably Never Heard of

It is a regrettable fact that science has historically undervalued the contributions of women. Elizabeth Stern is probably one of the most significant physician-scientists who worked at the interface of epidemiology and cancer in the mid-20th century, but it is unlikely you have ever heard her name. You won’t read about Stern’s research in medical … Read more

Few journals heed calls to boycott Russian papers | Science

Since Russian forces invaded their country, Ukrainian scientists have repeatedly issued a plea to the world’s journal editors: Punish Russia by declining to publish manuscripts from its scientists. But editors and publishers have largely refused the call. The journals cite a long-held principle in scientific publishing, enshrined by the International Science Council and other organizations, … Read more

Controversial impact crater under Greenland’s ice is surprisingly ancient | Science

In 2018, an international team of scientists announced a startling discovery: Buried beneath the thick ice of the Hiawatha Glacier in northwest Greenland is an impact crater 31 kilometers wide—not as big as the crater from the dinosaur-killing impact 66 million years ago, but perhaps still big enough to mess with the climate. Scientists were … Read more

Congress poised to boost U.S. science funding, launch new health agency | Science

U.S. research agencies would get budget boosts of roughly 5% this year under a final 2022 spending bill that congressional leaders unveiled early today and hope to pass in the next few days. But those amounts fall far short of aspirational funding levels for several science agencies that Congress is weighing under separate legislation now … Read more

In a first, state bill would require nearly perfect welfare record for research dog and cat suppliers | Science

A major supplier of dogs and other animals for academic and corporate research, which was cited last year for dozens of Animal Welfare Act (AWA) violations at its Virginia beagle-breeding facility, was targeted by the state’s lawmakers this week. On 7 and 8 March, both houses of the Virginia General Assembly unanimously passed a bill … Read more
