No defects found in reproductive ability of male mice returning from short stay in space

Male mice raised in space using specially developed cages were returned safely to Earth. The sperm production/fertilizing ability of the mice were normal and the reproduction ability of the offspring were not affected by their parents' stay in outer space. The findings on the effects of the environment in space on the male reproductive system will contribute to the accumulation of basic knowledge for humankind to expand the range of its activity to space.

Hello, world! A new approach for physics in de sitter space

For decades, physicists have been attempting to reconcile quantum mechanics, the physics of the very small, with gravity, the physics of the very large. While many academics are working on quantum gravity, they often use models that don't consider certain aspects of our own universe, like its accelerated expansion. A team reports a new approach to quantum gravity using a model that more closely matches our reality.
