  • Maybe we’re a little hasty in shout-out to aliens Feb 28, 2015 8:47 PM
    “We have already sent signals into space that will alert the aliens to our presence with the transmissions and street lighting of the last 70 years,” Seth Shostak, an astronomer at the SETI Institute and a supporter of the more aggressive approach, has written. “These emissions cannot be recalled.”That’s true only to a point, say the critics of active SETI. They argue that unintentional planetary leakage, such as “I Love Lucy,” is omnidirectional and faint, and much harder to detect than an intentional, narrowly focused signal transmitted at a known planet.

  • Herbicides play role in shrinking monarch population Feb 28, 2015 2:32 PM
    President Barack Obama issued a directive last year to federal agencies to create a strategy to promote the health of honey bees and other pollinators, and as part of the effort, the federal government pledged $3.2 million in February to restore habitat from California to the Corn Belt. And there has been some good news as drought conditions eased, with monarchs experiencing a 69 percent spike in the size of their overwinter habitat in Mexico, although that population remained the second smallest since the World Wildlife Fund in Mexico began record-keeping in 1993.

  • Antarctica’s retreating ice may re-shape Earth Feb 27, 2015 4:13 PM
    Just last month, scientists noticed in satellite images that a giant crack in an ice shelf on the peninsula called Larsen C had grown by about 12 miles in 2014. Ominously, the split broke through a type of ice band that usually stops such cracks. If it keeps going, it could cause the breaking off of a giant iceberg somewhere between the size of Rhode Island and Delaware, about 1,700 to 2,500 square miles, said British Antarctic Survey scientist Paul Holland.
