Neurosecurity: security and privacy for neural devices.
"An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define 'neurosecurity'—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices."

Imagine nature's most elegant ideas organized by design and engineering function, so you can enter "filter salt from water" and see how mangroves, penguins, and shorebirds desalinate without fossil fuels. That's the idea behind AskNature
, the online inspiration source for the biomimicry
community. The featured pages
are a good starting point. Cross-pollinating biology with design. [more inside]

- Manipulate LEGO TECHNIC gears, beams, conveyor belts and motors to complete the ten pre-built puzzles or create your own levels. [In my case - Then watch them crash in a heap when you test them.]

A glance will show / Why Phoebe Snow / Prefers this route / To Buffalo.
And Phoebe's right / No route is quite / As short as Road / of Anthracite.
In 1908 the Delaware, Lackawanna and Western Railroad began work on the New Jersey Cut-Off
to make its New York to Buffalo mainline (the Road of Anthracite so liked
by Phoebe Snow
) even shorter and faster. It was to have no grade crossings, and was to be as straight and level as possible — through hilly terrain. The 28-mile Lackawanna Cut-Off
, as it is now known, was built over three years, cost $11 million, and was an engineering marvel
of massive reinforced concrete bridges, enormous cuts, and the largest railroad embankment in the world. All of this has been abandoned
for years, though there are plans afoot to restore the Cut-Off for commuter rail
. [more inside]

The coming memristor revolution in electronics and how it works.
The newly created memristor, only the fourth fundamental fundamental type of passive circuit element, has the promise of computing advances both prosaic (faster, cheaper and "bigger" flash drives) and momentous (relatively effortless mimicry of brain cells and their activity). This is the story of the memristor's genesis, told by R. Stanley Williams, the leader of the team that created the device. [more inside]

Flawless Aircraft Emergency Landings
(QLYTP). Breatheless reporting aside, it looks like when a pilot can control the landing, these aircraft are tough enough that no one need be hurt. Many more excellent videos in the post-video links, too.

In a single 1931 document
, electrical engineer Alan Blumlein
patented stereo records, stereo movie sountracks and surround sound. His equipment was used to make some of the first stereo recordings
at EMI's Abbey Road studios - several decades before the technology came into popular use. Blumlein went on to pioneer 405 line TV
(the first wholly electronic format which won out over John Logie Baird's rival system) and to produce the equipment that made the first outside TV broadcast
possible. At the outbreak of World War 2 he was a key architect of the secret H2S
radar project. Unfortunately he was killed in a plane crash while testing the technology and the whole incident was kept secret. Hence he remains an obscure figure despite his achievements. A recent BBC Radio 4 program
contains a lot of the archive stereo footage and tells his story.

Later this year, geophysicist Dan Lathrop's DIY Planet Earth
will be filled with liquid sodium, weigh in at 26 tons, and will be spun-up to 80mph at its equator in an effort to discover how the earth's magnetic field is generated. Currently undergoing tests, even those can be pretty impressive

When programmers kill.
[pdf] In 1982, Atomic Energy Canada, Limited, introduced the now-infamous Therac-25, a solely software-driven successor to its earlier medical linear accelerators. Six patients
received massive amounts of radiation, and three died, before AECL was compelled to supplement the (faulty) software-only error-checking with hardware interlocks to prevent overexposure. [more inside]

are the names of four artificial islands immediately off the Southern California port of Long Beach. From the shore
, they each look like an inhabited island paradise
, complete with waterfalls, interesting buildings, many palm trees and crazy nighttime party lighting
. In fact, they are offshore oil wells
, built on 10 acre Dubai-esque man-made islands created for the purpose of housing the oil wells
, and disguised so as to comply with local aesthetic standards.

For years, MDI
has been developing a car that runs on compressed air. Last month, they signed an agreement
with Tata Motors to produce the MiniCat - a zero-emissions vehicle that will travel up to 180 miles on $3 worth of fuel. See it in action here
