Within days, NASA's robotic rovers and orbiters working on Mars will go silent.
Starting today, communication with all machines working on Mars will become spotty -- and within about a week should stop all together, according to Richard Zurek, chief scientist in the Mars Program Office at NASA's Jet Propulsion Laboratory.
The strategy uses a technique called gravitational microlensing, currently used by a Japan-New Zealand collaboration called MOA (Microlensing Observations in Astrophysics) at New Zealand's Mt John Observatory. Their work will appear in the Oxford University Press journal Monthly Notices of the Royal Astronomical Society.
Lead author Dr Phil Yock from the University of Auckland's Department of Physics explains that the work will require a combination of data from microlensing and the NASA Kepler space telescope.
A dark matter-hunting telescope perched on the International Space Station has spotted millions of particles of antimatter. It could be the first clear evidence of dark matter particles smashing into each other – or something much more mundane.
"It's an indication, but by no means is it a proof" of dark matter, says Nobel laureate Samuel Ting of the Massachusetts Institute of Technology, the principle investigator for the Alpha Magnetic Spectrometer experiment.
In 1936, Alan Turing showed that all computers are simply manifestations of an underlying logical architecture, no matter what materials they're made of. Although most of the computer's we're familiar with are made of silicon semiconductors, other computers have been made of DNA, light, legos, paper, and many other unconventional materials.
I recently posted about Brain Games, the new National Geographic TV show with mind-bending interactivity, and shared an infographic about intelligence. I follow that with an infographic my friend just made for Veracode on hacking the mind–perhaps a dark side of brain science.
Earlier today I was listening to one of my favorite podcasts, The Drill Down, and Dwayne D. mentioned how frustrating it is for many people to juggle multiple passwords, especially those that need to change frequently.
