US FAA Finds No Blue Origin Safety Issues After Review

The United States Federal Aviation Administration said on Friday it had found no safety concerns after investigating allegations against Blue Origin’s manned space flight program. The FAA announced in September that it would review safety concerns raised by former Blue Origin employees.

With the help of a laboratory, whiskey distillers avoid aging in oak barrels. What does it taste like?

In a small laboratory in Silicon Valley, California, Martin Janousek and Stu Aaron make whiskey. There are no oak barrels stacked from floor to ceiling. In fact, there is almost no wood at all. Instead, they use syringes, beakers, and flasks to find a more sustainable way to distill whiskey.

Footprints in Spain show carnivorous dinosaurs were fast and furious

It is almost not fair. The carnivorous dinosaurs were armed with menacing teeth inside muscular jaws, brandished dangerous claws on their hands and feet, and boasted of a keen sight and smell. And, as new research confirms, some were pretty quick as well. Two fossilized footprints from the Cretaceous period discovered around 120 million years ago in the La Rioja region of northern Spain show that the medium-sized carnivorous dinosaur species that made them could run to around 45 km / h, scientists said on Thursday.

Japanese researchers use ostrich cells to make illuminated COVID-19 detection masks

Japanese researchers have developed masks that use ostrich antibodies to detect COVID-19 by glowing under ultraviolet light. The discovery of Yasuhiro Tsukamoto and his team at Kyoto Prefectural University in western Japan could allow low-cost home testing of the virus, they said in a press release.
