By Will Dunham WASHINGTON (Reuters) - If you want to know how vampire bats can survive on a diet that -- as everyone knows -- consists exclusively of blood, the answer is simple. Scientists on Monday said they have mapped for the first time the complete genome of a vampire bat, finding that this flying mammal boasts numerous genetic traits that help it thrive on an exotic food source that offers nutritional disadvantages and exposes it to blood-borne pathogens. The researchers compared the genome of the common vampire bat, scientific name Desmodus rotundus, to genomes of bat species that eat nectar, fruit, insects and meat.
NASA has had an incredible streak of good luck as of late with spacecraft that have far outlived their expectations. Cassini at Saturn, the Opportunity rover on Mars, and several other pieces of high-tech space hardware have performed for much longer than was initially expected of them. Unfortunately, the Mars Reconnaissance Orbiter, which was launched in 2005 and has delivered more data on the Red Planet than any other Mars mission, is starting to cause some headaches.
According to NASA's Jet Propulsion Laboratory, the spacecraft has been put into "precautionary standby status" after it alerted its handlers of low battery voltage. The craft is equipped with solar panels that power its instruments, but when it swings to the dark side of the planet it relies on rechargeable batteries to keep it up and running. Now, NASA has to figure out exactly what is wrong, and do so from over 30 million miles away.
"We're in the diagnostic stage, to better understand the behavior of the batteries and ways to give ourselves more options for managing them in the future," MRO Project Manager Dan Johnston explains. "We will restore MRO's service as a relay for other missions as soon as we can do so with confidence in spacecraft safety, likely in about one week. After that, we will resume science observations."
NASA is optimistic that they can iron out whatever issues are leading to the spacecraft's battery woes, but it's not exactly shocking that the hardware is having problems when you consider its age. Launching in 2005, the Mars Reconnaissance Orbit was slated to have a two-year mission window which it completed with flying colors. Following that success, NASA has issues extended missions five times, allowing the orbiter to continue gathering and relaying a treasure trove of data about the planet. According to NASA, the MRO has delivered over 317 terabits of data thus far, which is more than all other Mars mission combined.
In just a couple of years, NASA is slated to launch its Mars 2020 mission which will feature the delivery of a new rover to the Red Planet. The rover will be a cutting-edge piece of scientific hardware capable of making advanced observations about the composition of the Martian surface.
WASHINGTON (AP) — There is no Harvard study that says a British children's television cartoon causes autism, despite what a social media post claims. In fact, there's at least one peer-reviewed study that hints that a children's television show may help autistic kids.

The French government announced Monday it will allow the wolf population to grow 40 percent despite pressure from farmers in mountain regions who are worried about their sheep flocks. A new strategy unveiled by the centrist government of President Emmanuel Macron will enable the number of wolves to increase from an estimated 360 now to 500 by 2023. Hunting wiped out the grey wolf in France during the 1930s and they only returned in 1992 via Italy -- currently home to around 2,000 wolves -- before spreading into Switzerland and Germany.
Here a cuttlefish can be seen camouflaging itself against the algae-covered rocks that surround it. “The biggest surprise for us was to see that these skin spikes, called papillae, can hold their shape in the extended position for more than an hour, without neural signals controlling them,” Paloma Gonzalez-Bellido, from the University of Cambridge, an author of the study, said in a statement.

The midlife crisis guy is an easily recognizable cultural archetype. Maybe he’s got a big stupid Corvette and a small dumb hat to match his crippling self-doubt. Maybe he’s hitting on a waitress. Maybe he’s letting a marriage dissolve. He’s a pathetic sort of villain facing down a long-deferred personal reckoning with failure and feelings. But...

Humans are fascinated by aliens. Whether they’re chest-bursting assassins or cuddly childhood friends, pop culture is awash with extraterrestrials. Science, too, has been looking for little green men for years with the Search for Extra-Terrestrial Intelligence (SETI) Institute and more recently with Breakthrough Listen.
