The two miniature water worlds, designed by former Biosphere 2 crew members, have been safely transferred to the American space shuttle Atlantis for comprehensive testing of their effects on plants and animals in space. The experiments aim to provide insights into long-term human spaceflight and pharmaceutical research.
Researchers found that Bcl-xL protein can insert itself into artificial membranes, allowing ions to pass through normally impermeable barriers. This discovery suggests a potential lead on how these proteins regulate cell survival and coordinate cellular activities.
A new Cornell University study warns that water shortages will worsen globally unless resource-management practices improve. The report suggests ending irrigation subsidies and rewarding conservation to manage water more efficiently.
