Philae was moved Friday so that solar panels could recharge the depleted batteries. But on Saturday, there was still no communication with the comet lander.
Could Cape Cod become cod-free? Google seeks to curb overfishing.On Thursday, NOAA abruptly cut short the fishing season for Atlantic cod, which has experienced severe population decline in recent years. That same day, Google Earth Outreach and two partner organizations released a prototype of a new online platform to track overfishing.
