NASA Is Building a $127 Million Space Mechanic
Artist’s concept of Restore-L. Image: NASA You would never buy a hundred million-dollar computer without a repair plan, but that’s exactly what NASA does when it sends costly satellites into space. To ensure that its prized eyes-in-the-sky don’t become the solar system’s most expensive e-waste, the space agency is now building a robot capable of repairing and refueling satellites in orbit. NASA has just announced that it will award a $127 million contract to the California-based satellite c..>> view originalHow Lasers and a Goggle-Wearing Parrot Could Aid Flying Robot Designs
A barely visible fog hangs in the air in a California laboratory, illuminated by a laser. And through it flies a parrot, outfitted with a pair of tiny, red-tinted goggles to protect its eyes. As the bird flaps its way through the water particles, its ...>> view originalMystery of ancient Egyptian legs likely solved: They're Queen Nefertari's knees
The mummified remains. (CC 2016 Habicht et al./PLOS One) In 1904, the pioneering Italian archaeologist Ernesto Schiaparelli cracked open a tomb in Egypt’s Valley of the Queens. The crypt, which had been lost for millennia, showed signs of long-ago disaster. Two things were clear to the archaeologist: This tomb was once the final resting place of Queen Nefertari. And, plunderers looted the burial site in antiquity, possibly within a few hundred years of its royal inhabitant’s death. The 3,200..>> view originalCaesarean births may be 'affecting human evolution': Study
Continuous usage of caesarean sections or c-section may be impacting human evolution as more mothers now need surgery to deliver a baby due to their narrow pelvis size, scientists say. C-section is the delivery of a baby through a surgical incision in the mother's abdomen and uterus. "Women with a very narrow pelvis pass on their genes encoding for a narrow pelvis to their daughters," Philipp Mitteroecker from the University of Vienna in Austria, was quoted as saying to bbc.com.

The amount of sea ice at both the Antarctica and the Arctic has hit record lows, leading scientists to worry that the effects of global warming might be far worse than previously thought. The worrying findings come after an area roughly the size of India melted away because of rising global temperatures and bizarre weather. Despite global warming and melting elsewhere, ice in the Southern Ocean off Antarctica has tended to expand. But it is now quickly shrinking at both ends of the planet, lead..>> view originalHow NASA (and the internet) would respond to the discovery of a killer asteroid
Here is one good and accurate plot for a science fiction movie courtesy of NASA.Humanity has a catastrophic problem. We still have no solid barrier against killer asteroids and other space rocks that lurk around our planet.According to British physicist Stephen Hawking, a NEO, or a near-Earth object, is a major threat to humanity.“One of the major threats to intelligent life in our universe is high probability of an asteroid colliding with inhabited planets,” said the renowned scientist in a vid..>> view originalThese 'crazy ants' love to munch on cellphones and TVs. Are they headed your way?
Of the nonnative animals crawling, buzzing and slithering across the American South, very few are officially designated "crazy." The crazy ant is an exception. When a Texas exterminator, Tom Rasberry, spotted ants moving in an erratic swarm in 2002, the strange insects took his name: Rasberry crazy ants. A decade later, after biologists completed the species' taxonomic identification, they renamed the ant in Latin Nylanderia fulva. In English, they dropped the Rasberry but kept the crazy, and n..>> view originalWhat can we learn from Google's time-lapse photography?
Evidence of rapid change across the earth’s surface in the past three decades is now readily available, thanks to new technology and satellite imagery compiled by Google that shows the impact of human activity and development on nature.Using Google’s latest toy, “Timelapse,” it’s possible to scroll over cities, landmarks, and natural wonders, watching as they develop or shrink between 1984 and 2016. The video service pulls more than 5 million satellite images largely from the Landsat project, a..>> view originalYup, Trump met with Al Gore. But his transition tells a very different story
Former Vice President Al Gore talks to the media after meeting with President-elect Donald Trump at Trump Tower on Dec. 5 in New York City. (Photo by Kevin Hagen/Getty Images) On Monday, an eyebrow-raising meeting between Donald Trump and former vice president Al Gore added fuel to recent speculation that the president-elect might be softening his stance on climate change, which he’s famously referred to in the past as a “hoax invented by the Chinese.” Gore later told reporters that the meet..>> view original
