Protected land reserved for Brazil’s indigenous communities is being traded on the social network.

An international team of scientists has developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in today’s digitally connected world.

New research throws wide open the amount of information that can be simultaneously transmitted by a single light source.

Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips.

The new work, reported in a paper published Thursday, February 252021, in the journal Nature Physics, throws wide open the amount of information that can be multiplexed, or simultaneously transmitted, by a coherent light source. A common example of multiplexing is the transmission of multiple telephone calls over a single wire, but there had been fundamental limits to the number of coherent twisted lightwaves that could be directly multiplexed.

A team of researchers at security firm Red Canary has found evidence of a new kind of malware infecting Apple brand computers. They claim on their website that they have found evidence of the malware, which they have named Silver Sparrow, infecting up to 30000 Mac computers.

Great new episode with the details on how NASA JPL’s successful Mars rover program kept the Perseverance rover on track. JPL chief engineer Rob Manning gives us an inside look at the strategies NASA used to make sure the latest rover made a spectacular landing.

NASA’s Rob Manning, JPL’s Chief Engineer, discusses management, logistics, innovation and the future of robotic Mars exploration in this unique episode. With this week’s successful landing of the Perseverance rover on an ancient river delta, NASA ups its game at a time when the rest of the country badly needs some encouraging news. Manning talks about how JPL keeps itself on track when finessing complicated billion-dollar initiatives.

A video of Martian Ripples in the highest quality. All the images you’re going to see are taken by NASA rovers and orbiters in Mars, boosted in quality with AI technology.

The wind has shaped the Martian landscape for much of its history and continues to play a major role today. Here we analyzed Martian Ripples and the similarities they have the ripples here on Earth.

Other information that can be found in this video:
📌- Real images of Martian Ripples.
📌- The density of the Martian Atmosphere.
