NASA's Mars 2020 rover tests descent-stage separation
In this picture from Sept. 28, 2019, engineers and technicians working on the assembly and testing of the Mars 2020 spacecraft look on as a crane lifts the rocket-powered descent stage away from the rover. They've just completed a successful separation test at NASA's Jet Propulsion Laboratory in Pasadena, California.
Museum of the Bible quietly replaces questioned artifact
The Museum of the Bible in Washington quietly replaced an artifact purported to be one of a handful of miniature Bibles that a NASA astronaut carried to the moon in 1971 after an expert questioned its authenticity.
Scientists: Red tide is back in Florida's southwest coast
Scientists say toxic red tide is back in the waters off the Florida southwest coast after fading away earlier this year following a 15-month bloom.

- 19/10/5 19:40
Researchers have built what they believe is 'the world's most efficient single-photon source.' And they are still improving it. With planned upgrades, the apparatus could generate upwards of 30 photons at unprecedented efficiencies. Sources of that caliber are precisely what's needed for optical quantum information applications.
Scientists find way to quantify how well cutting-edge microscopy technique works

Scientists provide a foundation for quantitatively determining how differences in viewing angles affect the resulting 3D structures of proteins, and could help other researchers determine the best setup for experiments to improve the imaging technique called cryo-EM.
Treating pulmonary embolism: How safe and effective are new devices?
- ScienceDaily
- 19/10/5 19:40
A new scientific statement identifies the risks and benefits of novel interventional devices compared to anticoagulation alone in the treatment of patients with pulmonary embolism. Authors conclude there is little data -- particularly, as it pertains to the treatment of patients with 'intermediate-risk PE' -- that suggests these interventional approaches are more safe and effective than the use of...
Anesthetizing fish may affect research outcomes

Fish use colorful patterns to signal to each other, including advertising for mates and warding off rivals. Studying the relationship between color and behavior sometimes entails anesthetizing and photographing the fish, but anesthetics may alter coloration, influencing the traits researchers are trying to study.
