BSOD from SPACE

Blue Screen of Death (BSOD)

Pretty much everyone knows what the blue screen of death is. That dreaded complete system failure that happens every so often. Sometimes for no reason at all. It can happen on any device – PC, Mac, Android, iOS/iPhone… most of the time the device just reboots.

Any number of issues can cause them – software bug, hardware driver issue, poorly manufactured hardware, an operating system (OS) error, malware (like viruses, adware, etc.). However, those times when it just seems to happen out of the blue (pun intended) might be because of space. Yes, that big blue-in-the day, black-in-the-night thing above you.

Inkless Paper Developed

Purple glow within a shade containing an ultraviolet (UV) light bulb.

Phys.org reports on a breakthrough in printing: paper that uses ultraviolet light to print on coated paper. The paper can be heated to 250°F to erase what was printed and re-written to it up to 80 times (re-writable paper).  The researchers believe that this paper, which uses ultraviolet light to speed up chemical reactions between titanium dioxide and Prussian Blue [Bob Ross, anyone?] pigment, can be produced cheaply on a commercial scale. Given that all the required materials – paper, titanium dioxide (already heavily used in beauty products/makeup, sunscreen, and as pigments for medicines, toothpaste, lipstick, creams, etc.), Prussian Blue pigment/dye, and ultraviolet bulbs – are all inexpensive means the materials are likely to be affordable. However, there are a few drawbacks:

Fiber Picks Up Speed

Fiber optic wires spread apart and sending out light.

Our demand for data continues to grow and so to does the amount of data fiber optic networks can transmit. Phys.org reports on research completed by NTT Access Network Service Systems Laboratories in Japan where they were able to fit 12 individual cores inside a standard diameter for fiber optics. Since the amount of data we can pack into current single-core networks is approaching maximum – meaning more fiber optic lines need to be laid to transmit the same amount of information – research into optical wires that contain multiple single cores is picking up. While this is not yet ready to be deployed out in the field it does bring such upgrades a step closer by producing a wire which experiences less distortion than similar multi-core wires. They are now looking to continue scaling up as well as find solutions to make multi-core fibers require less complex signal processing.
