  1. Re:I was always suspicious of this on The Adult Brain Does Grow New Neurons After All, Study Says · · Score: 1

    ...............
    Each section of the brain has RISC like processing dedicated to certain skills, sensory, knowledge, understanding, and logic. But also shows CISC like adaptability as we also have evidence of an area of the brain remapping to perform other tasks not originally processed there. ...................

    The brain must be some sort of FPGA

  2. Toxic aminoacids on Eating Processed Foods Tied To Shorter Life, Study Suggests (theguardian.com) · · Score: 1

    I suspect part of the aminoacids of the protein in food are chemically changed by the industrial processing to unnatural toxic aminoacids.

    Here are examples of toxic aminoacids:

    I suspect the body could use the unnatural aminoacids to build proteins. Those proteins could cause proteopathy, like for example alzheimer's.

  3. Magnetic properties on Scientists Discover a New Kind of Magnet (ieee.org) · · Score: 1

    If the magnetism goes away quickly, the material wouldn't be suitable for mass storage such as a harddisk of magnetic tape. However, then it could be suitable as a core of a coil, the same as a coil with a ferrite core.

    Is this material diamagnetic, paramagnetic of ferromagnetic?

  5. Multicore will be next on Intel CPUs Impacted by New PortSmash Side-Channel Vulnerability (zdnet.com) · · Score: 5, Insightful

    If a hyperthread can spy on the other hyperthread that runs on the same core, it is possible to disable hyperthreading.

    However, the next exploit will be that one core can spy on another core. This is possible because all cores use the memory subsystem including the L3 cache that is shared between all cores.

  6. Spectre or meltdown on Mysterious $15,000 'GrayKey' Promises To Unlock iPhone X For The Feds (forbes.com) · · Score: 1

    This might exploit some spectre or meltdown like vulnerability to get the encryption keys that are located in an until now safe part of the processor chip.

  7. If you have a quadcore processor, would it be possible to run the kernel and nothing else on 1 core, and use the other 3 cores for user programs?

    Would the above prevent user programs to access kernel memory that shouldn't be accessible to user programs?

  10. RFID pressure sensor on NFL Releases Deflategate Report · · Score: 1

    They should build a rfid pressure sensor in the balls.

    That way the pressure can be checked just before the ball will be used in the game. Balls with a wrong pressure can be inflated / deflated or rejected immediately.

    Some alien scouts have recently landed on earth. Right now, the alien scounts are investigating the best way to invade earth. They have found 'humans', and learned that humans use something called 'internet' to ask for information.

    The aliens were detected when they submitted a question to slashdot to investigate if their invasion would be detected.

  12. Hypoxic air technology for fire prevention on Former NATO Nuclear Bunker Now an 'Airless' Unmanned Data Center · · Score: 2

    Hypoxic air technology for fire prevention

    Hypoxic air technology for fire prevention, also known as oxygen reduction system, is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms. Unlike traditional fire suppression systems that usually extinguish fire after it is detected, hypoxic air is able to prevent fire.

    Design and operation

    Air with a reduced oxygen content is injected to the protected volumes to lower the oxygen concentration until the desired oxygen concentration is reached.

    Air with low oxygen concentration is produced by hypoxic air generators, also known as air splitting units.

    Effects on health

    Fire-prevention systems which result in the oxygen content being less than 19.5% are not permitted for occupied spaces by federal regulation (OSHA) in the United States [3].

    However, hypoxic air is considered by some to be safe to breathe for most people.[6] Medical studies have been undertaken on this topic. Angerer and Novak's conclusion is that "working environments with low oxygen concentrations to a minimum of 13% and normal barometric pressure do not impose a health hazard, provided that precautions are observed, comprising medical examinations and limitation of exposure time".[7] Küpper et al.[8] say that oxygen concentration between 17.0-14.8% does not cause any risk for healthy people by hypoxia. It also does not cause risks for people with chronic diseases of moderate severity.

  19. TRAFFIC "EXPERIMENTS" AND A CURE FOR WAVES & J on Boston Using IBM Engineers To Solve Traffic Problems · · Score: 2

    TRAFFIC "EXPERIMENTS" AND A CURE FOR WAVES & JAMS
    1998 William Beaty Electrical Engineer

    My first 'experiment': accidentally erasing waves!
    Once upon a time, years ago, I was driving through a number of stop/go traffic waves on I-520 at rush hour in Seattle. I decided to try something. On a day when I immediately started hitting the usual "waves" of stopped cars, I decided to drive smoothly. Rather than repeatedly rushing ahead with everyone else, only to come to a halt, I decided to try to move at the average speed of the traffic. I let a huge gap open up ahead of me, and timed things so I was arriving at the next "stop-wave" just as the last red brakelights were turning off ahead of me. It certainly felt weird to have that huge empty space ahead of me, but I knew I was driving no slower than anyone else. Sometimes I hit it just right and never had to touch the brakes at all. Other times I was too fast or slow. There were many "waves" that evening, and this gave me many opportunities to improve my skill as I drove along.

        I kept this up for maybe half an hour while approaching the city. Finally I happened to glance at my rearview mirror. There was an interesting sight.
    It was dusk, the headlights were on, and I was going down a long hill to the bridges. I had a view of miles of highway behind me. In the neighboring lane I could see maybe five of the traffic stop-waves. But in the lane behind me, for miles, TOTALLY UNIFORM DISTRIBUTION. I hadn't realized it, but by driving at the average speed of the traffic around me, my car had been "eating" the traffic waves. Everyone ahead of me was caught in the stop/go cycle, while everyone behind me was forced to go at a nice smooth 35MPH or so. My single tiny car had erased miles and miles of stop-and-go traffic. Just one single "lubricant atom" had a profound effect on the turbulent particle flow within the entire miles of "tube."

  25. Change the magnetic field to test on Scientists Discover Cows Point North · · Score: 1

    Maybe the cows orientate themselves away from the sun, and the magnetic field of the earth has nothing to do with it.

    To test the influence or lack of influence of the magnetic field of the earth on cows, it would be possible to locally change the direction of the magnetic field with a giant helmholz coil. Then they can see if the cows really orient themselves using the magnetic field, or not.
