But when you’re a multimillion-dollar spacecraft, caution is usually the only response you get preprogrammed with. Adding to poor beleaguered NASA’s spate of recent glitches, the Mars Reconnaissance Orbiter went into safe mode on Monday after suffering what appears to have…

It is only relatively recently that it has dawned upon humans that the ocean is not something that can be taken for granted. Vast, deep, unfathomable in so many ways, the great body of liquid that envelops our planet at an average depth of some six miles acts as the main regulator of our weather…

It seems fitting that in a year being celebrated worldwide as the 400th anniversary of telescopic astronomy, NASA and ESA have chosen one of Galileo’s first loves, Jupiter, as their next top planet. Cut-away images show the insides of Io, Ganymede, … In January of 1610 the famed Italian Galileo Galilei pointed a homemade ‘scope…

The New Electric Mini-Cooper

Chionodraco hamatus, one of the Antartic’s ice fish, can withstand temperatures that freeze the blood of all other types of fish, Census of Marine Life scientists reported today. The ice fish is sometimes called a bloodless or white-blooded fish, because it lost its ability to make hemoglobin during its evolution.This makes the fish a medical…

Without decisive action, global warming in the 21st century is likely to accelerate at a much faster pace and cause more environmental damage than predicted, according to a leading member of the Intergovernmental Panel on Climate Change (IPCC). “There is a real risk that human-caused climate change will accelerate the release of carbon dioxide from…

The birds and the bees don’t celebrate Valentine’s Day, of course, but some certainly have bizarre mating rituals. Some of the stories National Geographic News published about this over the years included pandas watching porn, damselfly mating games that turn males gay, spiders that glow with fluorescence in the presence of potential mates, gorillas mating in the…
