The brain can store 1 petabyte of memories, or 13 years of HD video

Jeff Williams | Feb 22, 2016 8:01 AM CST

Researchers at the Salk Institute for Biological Studies have made a pretty startling discovering, finally figuring out just how large a capacity our brain actually has when put in normal computing terms. With the help of GPU computing they figured out that we can store around one petabyte, which is nearly 10 times larger than what we originally thought.

Modeling the full function of the brain isn't easy, and even with clusters of GPU powerhouse servers it takes time to properly model the actual function of the connection between neurons, the synapses. The team of researchers modeled the full hippocampus of a rat with startling accuracy and 26 different sizes of synapses. Size matters, apparently, and the bigger the more storage the accompanying neurons have. They found that the average amount of information that can be held in one synapse is around 4.7 bits, far more than we thought previously.

The amount of information stored and transferred across those still misunderstood synapses doesn't translate directly to computing terms, however. We obviously don't store our moving memories as GIF's or even H.265 encoded MPEG's either. In fact, our brain is incredibly efficient, moving information across the synapse at a rate of around 10-20% of the time.

NASA's new 'WFIRST' space telescope sees 100x more than Hubble can

Anthony Garreffa | Feb 21, 2016 1:29 PM CST

Up until now, the Hubble Space Telescope was the one that was looking to the utter edges of the universe, taking a few photos and blowing the world away each time. Well, NASA could retire Hubble very soon with its new WFIRST telescope.

The Wide Field Infrared Survey Telescope (or WFIRST) has a field of view 100x larger than Hubble, and it's designed to block the glare from individual stars, which will make NASA's job of finding the chemical makeup of exoplanets easier. NASA won't launch WFIRST until the mid-2020s, so we should see the James Webb telescope that will be finished in 2018 be the champion until at around 2025 or so.

Once NASA has WFIRST online, it will provide a view of space that we've never seen before. NASA should be better capable of understanding the shape of the universe, as well as provide the US space agency with more insight into how dark energy and dark matter work, which could solve some very big problems and mysteries we have here on Earth.

LG's new Rolling Ball works with the company's new G5 smartphone and turns it into a remote that can control the Rolling Ball from anywhere in the world. It features an on-board camera that records footage, but it's also a speaker that lets you speak through it - like, to your pet. LG's Rolling Ball also includes an IR blaster that lets you turn your TV on, from your smartphone, through the Rolling Ball.

The hardware powering the LG Rolling Ball are found in the center stripe, with the two large hemispheres are the engine that turns the robot in any direction. LG isn't talking about the price on the Rolling Ball just yet, but we should find out in the near future.

Tatooine found, cool photos of developing planet in a binary system

Jeff Williams | Feb 15, 2016 8:00 AM CST

It's not unusual these days to find evidence of new world's hanging out beyond our solar-system. The original Kepler project found thousands of candidates that are still being confirmed as potential exo-planets. But finding nearly visible evidence of a planet being formed in the presence of the harsh conditions of a binary star system? That doesn't come along every day.

Just 450 light-years away, shining brightly in the constellation Taurus, the HD 132527 star system just birthed a new planet, and it's been caught in some stunning high-resolution photos from both the Hubble telescope in the past and now from the Atcama Large Millimeter/sub-millimeter Array (ALMA) by researchers at Rice University. This is the first time we've ever had clear evidence of what planet formation actually looks like.

There's a tremendous amount of detail being recorded right now by the ALMA array, and it shows dust and gases coming together to actually make a planet. In the photo above, the bright red is where there's the most dust and where carbon monoxide is appearing. That gas is freezing inside the dust, clumping together to form solid rock formations that seem to be sticking together, making an even larger object.

Within 30 years, AI 'could leave half of world unemployed'

Anthony Garreffa | Feb 14, 2016 8:23 PM CST

The threat of AI blowing up the world or keeping us in cages like animals might scare most people, but I think the prospects of AI could be truly transformative - and that we're bound by other things like society, religion, government and more - but according to one scientist, AI "could leave half the world unemployed".

According to Moshe Vardi, who told the American Association for the Advancement of Science (AAAS): "We are approaching a time when machines will be able to outperform humans at almost any task. I believe that society needs to confront this question before it is upon us: if machines are capable of doing almost any work humans can do, what will humans do?".

Vardi is a professor at Rice University Guggenheim fellow, adding that technology is a bigger threat than UAVs that some fear, adding that AI could see unemployment numbers hitting 50%, taking away middle-class jobs, and making the wealth gap even bigger.

Scientists begin tinkering on 'deleting' your unwanted memories

Anthony Garreffa | Feb 14, 2016 5:44 AM CST

It might seem like fantasy, but scientists have found a way to delete bad memories from your head - forever. The news is coming from a new documentary being shown in the US this week called "Memory Hackers".

Memory Hackers is a NOVA documentary from PBS, which looks into the cutting edge research being done on the nature of memory, and how it might be used for the benefit of mankind. The filmmakers said: "For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays it intact".

They continue: "But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories".

North Korean Satellite tumbling out of control, not even functional

Jeff Williams | Feb 10, 2016 2:34 PM CST

North Korea set a major record over the weekend following the launch of their first satellite -carrying rocket. The problem, however, is that the Kwangmyŏngsŏng-4 satellite doesn't even work at all. And it's tumbling about in orbit, on a trajectory to burn-up in orbit. And smash into the Earth.

The US Department of Defense and other agencies around the world have analyzed the orbital object and have determined that it's in an unstable orbit, and absolutely incapable of functioning in any useful way. Other than as a proof of concept.

Of course officials from various countries and the U.N. Security Council are worried that this test is a display of their technological prowess and a secretive way to test technologies that could evolve into better intercontinental ballistic missiles, or even spy satellites.

NASA provides MIT with humanoid robot, will help out space missions

Anthony Garreffa | Feb 10, 2016 6:19 AM CST

NASA has announced that it will be providing MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) with one of its huge 6-foot, 290-pound humanoid robots. MIT will use it to test and develop for future space missions to Mars, and beyond.

CSAIL Principal Investigator Russ Tedrake will work on algorithms for the robot, which is known as "Valkyrie" or "R5". Tedrake's work will be part of NASA's upcoming Space Robotics Challenge, with its missions to create more dexterous autonomous robots that will help, or one day replace humans on "extreme space" missions.

NASA says that it's interested in humanoid robots because they can assist, or replace humans working in extreme space environments. For future missions, humanoid robots can do tasks that humans simply can't do - like out in space itself, where humans die with a lack of oxygen - and that little thing called gravity.

Associate Administrator for the Space Technology Mission DiDirectorateSTMD) at NASA HQ in Washington, Steve Jurczyk, said: "Advances in robotics, including human-robotic collaboration, are critical to developing the capabilities required for our journey to Mars. We are excited to engage these university research groups to help NASA with this next big step in robotics technology development".

German nuclear fusion reactor yields hydrogen plasma for first time

Derek Strickland | Feb 4, 2016 6:30 PM CST

Fusion power is seen as the holy grail for renewable and clean energy sources. Harnessing the power of the stars would propel mankind to extraordinary heights, and instantly resolve our growing energy crises to boot. Now thanks to the nuclear fusion experiments conducted by the Max Planck Institute of Physics in Germany, we're one step closer to unlocking the secrets of fusion power.

The world's largest nuclear fusion stellarator, the Wendelstein 7-X, has just made history by being the first stellarator-type fusion device to produce hydrogen plasma. Hydrogen plasma is vital to re-creating and molding the specific conditions of our Sun, thus facilitating fusion reactions.

"It's a very clean source of power, the cleanest you could possibly wish for. We're not doing this for us, but for our children and grandchildren," Karlsruhe Institute of Technology physicist John Jelonnek said.
