Vision deterioration in astronauts who spend a long time in space is likely due to the lack of a day-night cycle in intracranial pressure. But using a vacuum device to lower pressure for part of each day might prevent the problem, UT Southwestern Medical Center researchers said.

Discovery Could Lead to Jet Engines That Run Hotter—and Cleaner

Researchers here have made a discovery in materials science that sounds like something from the old Saturday morning cartoon Super Friends: They’ve found a way to deactivate “nano twins” to improve the high-temperature properties of superalloys that are used in jet engines.The advance could speed the development of powerful and environmentally friendly turbine engines of all sorts, including those used for transportation and power generation.

Tigers Could Roam Again in Central Asia, Scientists Say

1ESFMikhailYurievichPaltsyn.Tiger.jpg

Caspian tigers, some of the largest cats that ever lived, roamed through much of Central Asia before they were designated as extinct in the middle of the 20th century. But there is a chance that tigers — using a subspecies that is nearly identical, genetically, to the Caspian — could be restored to Central Asia.
