Our Space Launch System Rocket’s “Green Run” Engine Testing By the Numbers

We continue to make progress toward the first launch of our Space Launch System (SLS) rocket for the Artemis I mission around the Moon. Engineers at NASA’s Stennis Space Center near Bay St. Louis,...

The timestamp that can tell an RNA molecule’s age — to the hour

Technique allows scientists to complete a timeline for gene activity in a single cell.

The first flying dinosaurs were a failed evolutionary experiment

Yi qi and Ambopteryx longibrachium, the first dinosaurs to take to the air, had wings made of membranes like bats, but they could barely glide and were soon outcompeted by birds

The Art of Hubble

Sometimes Hubble Space Telescope data is best visualized through art. Artists and scientists worked together to depict Hubble discoveries in these illustrations.

Promising sign of life on Venus might not exist after all

The detection of phosphine gas in the clouds of Venus—a possible sign of life—might be due to a fluke in data processing, new analyses suggest.

CRISPR turns normal body fat into a type that burns energy

This bird pesticide is legal, but recent deaths are stoking controversy

“Both physically and psychologically, it’s an awful way to die,” says one conservationist of the bird poison Avitrol. Cities around the U.S. and Canada agree—and some have banned it.

Cross-reactive neutralization of SARS-CoV-2 by serum antibodies from recovered SARS patients and immunized animals

The current COVID-19 pandemic is caused by SARS-CoV-2, a novel coronavirus genetically close to SARS-CoV, thus it is important to define the between antigenic cross-reactivity and neutralization. In this study, we first analyzed 20 convalescent serum samples collected from SARS-CoV infected individuals during the 2003 SARS outbreak. All patient sera reacted strongly with the S1 subunit and receptor-binding domain (RBD) of SARS-CoV, cross-reacted with the S ectodomain, S1, RBD, and S2 proteins of SARS-CoV-2, and neutralized both SARS-CoV and SARS-CoV-2 S protein-driven infections. Multiple panels of antisera from mice and rabbits immunized with a full-length S and RBD immunogens of SARS-CoV were also characterized, verifying the cross-reactive neutralization against SARS-CoV-2. Interestingly, we found that a palm civet SARS-CoV-derived RBD elicited more potent cross-neutralizing responses in immunized animals than the RBD from a human SARS-CoV strain, informing a strategy to develop universe vaccines against emerging CoVs.
