The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the disease caused by the virus. The immune response may explain rare clots after AstraZeneca vaccination seats for the first all-civilian space crew were filled

A college science professor and aerospace data analyst were named Tuesday to round out a crew of four for a SpaceX launch into orbit that will be billed as the first all-civil spaceflight in history later this year. The two newest citizen astronauts were unveiled at a press conference streamed live from the Kennedy Space Center in Florida by SpaceX chief of human spaceflight Benji Reed and billionaire entrepreneur Jared Isaacman, who designed the mission partly as a charity drive.

The SpaceX Starship SN11 rocket does not land safely after the test launch in Texas: SpaceX

An unscrewed SpaceX Starship prototype rocket failed to land safely on Tuesday after a test launch from Boca Chica, Texas, and engineers are investigating it, SpaceX said. “We seem to have lost all of the vehicle’s data,” said SpaceX engineer John Insprucker in a webcast video of the rocket’s flight test. “We have to find out from the team what happened.”

Pfizer / BioNTech Vaccine Safe, Effective in Adolescent Carnivorous dinosaurs with short snouts and strong bites threaten Patagonia

Scientists in Argentina have discovered the well-preserved skull of a carnivorous dinosaur that roamed northern Patagonia about 85 million years ago – an animal with a short snout, sharp hearing, and strong bite that made it a daunting predator. The dinosaur, named Llukalkan aliocranianus, was about five meters long and was a member of a carnivorous group called the abelisaurids that thrived in South America and other parts of the southern hemisphere during the Cretaceous.

Graffiti or homage? Hi-tech imaging illuminates the crosses on the walls of the Holy Sepulcher

Crosses etched in mysterious profusion over the walls of Christianity’s holiest church have long been considered graffiti, but they could be the work of medieval masons paid by pilgrims to carve them. Venerated in Christian tradition as the place of the crucifixion and burial of Jesus, Jerusalem’s Church of the Holy Sepulcher is usually full of worshipers and clergymen. This has made the study of the sacred markings difficult.
