Saturday's emergency spacewalk outside the International Space Station failed to replace the faulty cooling pump that malfunctioned last week, prompting NASA to schedule a third spacewalk in addition to the two already scheduled for the task. The second could be performed as early as Wednesday, giving NASA engineers time to consider the problem while lawmakers continue to mull NASA's future, which is pinned to the success of the ISS.
Egyptologists are hoping some 21st-century tech will help them unlock secrets from 4,500 years ago. They're using a robot to explore the Great Pyramid of Giza.
The robot will traverse two unexplored shafts leading from the Queen's Chamber in the pyramid. Nobody knows where the shafts, which were discovered in 1872, lead.
They're not making any more real estate; not until we colonize other planets at least. Laying out our dead horizontally, and leaving them in peace forever, is becoming an expensive proposition. That's why inventor Donald Scruggs has come up with the screw-in coffin.
Holding a body vertically, it is screwed down into the ground securely, to optimize graveyards' use of space.
Diabetics may have yet another tool in their blood-sugar management arsenal -- an implantable, fluorescent blood-sugar monitor. It involves small hydrogel beads that vary the intensity of emitted light depending on glucose concentration. They're called Life Beans.
The system, developed at the University of Tokyo, could lead to implantable blood-glucose monitors, which could enable 24-7 monitoring of a diabetic's blood sugar without having to prick the skin or use an attachable pump.
Shigeru Kondo spent some $18,000 to build a desktop Windows computer that, over the course of three months, shattered the world record for calculating pi. Running in the 54-year-old system engineer's home, where he lives with his wife and mother, the machine calculated pi to 5 trillion decimal places, nearly double the previous record of 2.7 trillion set by French programmer Fabrice Bellard late last year.
The Pentagon wants a U.S. fighting force with global reach, ready to deploy anywhere at any time and operate at full capacity. But while keeping our troops in shape and our powder dry are relatively easy tasks, environmental variables are out of our fighting force’s hands. As such, DARPA has awarded $4.7 million to researchers to come up with inhalable drugs that eliminate the negative impacts of high altitude on soldiers by helping their bodies to rapidly acclimate.
The much-hyped, rarely understood Google Wave project--essentially an email application with more intensive real-time collaboration and communication tools bolted on--will be developed no longer, Google announced in a blog post this afternoon. Can't say that it's much of a surprise.
Puzzle-loving gamers are better at solving molecular biology problems than a supercomputer, according to a new study published today in the journal Nature. Playing a game called Foldit, which involves protein folding, gamers outsmarted computers on problems that required radical moves, risks and long-term vision.
The researchers, based at the University of Washington in Seattle, are incorporating the best Foldit players' strategies into their own algorithms. Forget distributed computing -- this is distributed thinking.
In 2016, NASA and the European Space Agency will launch the first-ever joint U.S./Euro mission to Mars, and Tuesday they unveiled exactly what kind of toys the ExoMars Trace Gas Orbiter will have on board. Among the highlights: the Mars Atmospheric Trace Molecule Occultation Spectrometer (MATMOS) that can detect concentrations of gas down to parts per trillion.
