A new study suggests official flood risk plans for the San Francisco Bay Area may underestimate inundation due to sea level rise over the next century by nearly 4 to 91 percent.
Other coastal cities could face similar effects, even under best-case scenarios.

An amateur astronomer from Rosario, Argentina, has accomplished an historic first: capturing the initial moments of a supernova explosion on film.
Although astronomers spot hundreds of supernovas each year, none had previously spied the bright, brief moment when the shock wave first bursts out from the star’s interior — until now.

For stroke survivors, brain injury doesn’t always stop when the stroke has passed. Now, researchers at University of Arizona and Stanford University School of Medicine have moved one step closer to understanding why.

City lights drive back the night a little more each year, disrupting ecological cycles, and the switch from orange-yellow sodium lights to bluish-white LEDs might be making the problem worse.
