Hydrogen cars for the masses one step closer to reality, thanks to UCLA invention

UCLA Newsroom

UCLA researchers have designed a device that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars.

How tiger sharks are helping seagrass


A heatwave along Australia’s western coast in 2011 killed off many of the region’s treasured seagrass beds. While recovery of the marine ecosystem has been slow, scientists have discovered that tiger sharks are aiding in the regrowth of seagrass beds by scaring off grazers such as dugongs.
