SpaceX’s Crew Dragon capsule Endeavour splashed down in the Atlantic Ocean, off the coast of Jacksonville, Florida, with the Ax-1 crew onboard.

Gaining clarity about the factors that contributed to a runaway greenhouse state on Venus, Earth’s closest planetary neighbor, can also help improve models of what could one day happen to Earth’s climate.

“Ultimately, my motivation in studying Venus is to better understand the Earth,” Kane said.

At the Max Rady College of Medicine, University of Manitoba, in Canada, researchers have developed a stem-cell-based therapy that is regenerating spinal cords in laboratory animals and may become available for human clinical trials.

Blocking inhibitory molecules that cause neuronal cells to degenerate, and inhibit stem cell transplants may prove a breakthrough therapy.

Deep learning is one of the best technological advancements having numerous applications which leverage the neural network features for projects like neural enhance and the controversial face-swap technology used in deepfake videos.

Can humanity become a Type I civilization without causing our own Great Filter?

There are several ways we can measure the progress of human civilization. Population growth, the rise and fall of empires, our technological ability to reach for the stars. But one simple measure is to calculate the amount of energy humans use at any given time. As humanity has spread and advanced, our ability to harness energy is one of our most useful skills. If one assumes civilizations on other planets might possess similar skills, the energy consumption of a species is a good rough measure of its technological prowess. This is the idea behind the Kardashev Scale.

Russian astrophysicist Nikolai Kardashev proposed the scale in 1964. He categorized civilizations into three types: planetary, stellar, and galactic. A Type I species is able to harness energy on a scale equal to the amount stellar energy that reaches its home planet. Type II species can harness energy on the scale of its home star, and Type III can harness the energy of its home galaxy. The idea was further popularized by Carl Sagan, who suggested a continuous scale of measurement rather than simply three types.
