A Single Autonomous Car Has a Huge Impact on Alleviating Traffic


Just one autonomous car out of 20 vehicles can significantly alleviate traffic congestion, according to research from the University of Illinois.  The culprit behind many traffic jams is the variability in speed of human drivers — waves of excessive braking and acceleration that can cause long backups.  By avoiding jackrabbit starts and sudden stops, a more even driving pace inserted in the traffic flow by an autonomous car dramatically reduces variability-induced congestion.  What’s more, according to the research team fuel consumption is reduced by up to 40 percent when averaged across all the cars in the traffic flow.

Fortunately, it may not take very long to gain these advantages — more uniform driving can be accomplished with relatively simple control systems (think intelligent cruise control augmented by automated braking).  A completely autonomous vehicle is not required.

Handpainted scenes from the original Star Wars trilogy, with a link to a cool documentary on 1980’s special effects from Industrial Light and Magic.

Interesting recent gallery exhibit and some interviews with Tara Donovan.  See also this, and for a comprehensive look at her work, just Google “Tara Donovan” and look at the images.  Amazing stuff.

Why Do Gas Station Prices Constantly Change? Blame the Algorithm.  Retailers are using artificial-intelligence software to set optimal prices on thousands of items a day, sometimes as often as every hour.

Vantablack, the Darkest Substance Ever Made


This is not photoshopped…

The photo above shows two identical sculptures, one of which is painted with Vantablack, a carbon-fiber coating from surrey nanosystems. It is the darkest substance known to man, absorbing more than 99.96% of incident light; so dark that details disappear and laser light is not reflected.  The original version could only by applied by vapor disposition, but it can now also be sprayed onto a surface.  Find out more about its amazing properties at “A Visual Guide to Vantablack” and at Surrey Nanosystems.

States with the most NIH funding

Updated for fiscal year 2016:


California dominates in overall funding (above), but Massachusetts, DC, and Maryland stand out in NIH funding per capita (next chart).



Below, you can see more clearly how Massachusetts has the highest per capita and second highest overall level of NIH funding.  Not surprisingly, most of the U.S. biotech clusters are located in the outlier states along the top and right edges of this chart:

What’s Stored in DNA? An Old French Movie and a $50 Amazon Gift Card

So many people are now tapping into the internet and social media that the torrent of data they’re creating is outstripping the storage capacity of traditional devices such as hard drives, optical discs, and magnetic tape.

New research advances hope that the same genetic chemistry found in the building blocks of life may provide enough storage to handle the explosive growth of digital data; the entire internet in a single beaker.

The technology to encode digital information in DNA has progressed to the point where as much as 215 petabytes of data can be stored in a single gram of the material.  In fact, text, images, music videos, even an Amazon gift card bar code have all been encoded in DNA.

Last April, film industry giant Technicolor made DNA copies of a 1902 French silent film called “Voyage to The Moon,” widely considered the first science-fiction film.

DNA is also extremely stable — for example fragments of wooly mammoth DNA have been recovered from animals encased in permafrost.  Under dry storage conditions pure DNA should be even more long-lived.  Good luck reading a 10,000 year old DVD.

All told, the DNA process cost about $3,500 per megabyte of storage, comparable to the cost of the first computer magnetic disk drive introduced by the IBM Corp in 1956—a memory device so big it had it to be carried on a forklift. It could store 3.5 megabytes of data and leased for $3,200 a month.

The technology is still expensive and slow, but more improvements are on the way.  As an long-term archival material, it may be the storage medium of the future.

Read the news article at the Wall Street Journal, and the original scientific article in Science:  DNA Fountain enables a robust and efficient storage architecture.  More commentary is also here: DNA Could Store All the Worlds Data in One Room.

How Ikea’s Billy Bookcase Took over the World


The Billy bookcase is perhaps the archetypal Ikea product.

It was dreamed up in 1978 by an Ikea designer called Gillis Lundgren who sketched it on the back of a napkin, worried that he would forget it.

Now there are 60-odd million in the world, nearly one for every 100 people – not bad for a humble bookcase.

In fact, so ubiquitous are they, Bloomberg uses them to compare purchasing power across the world.

According to the Bloomberg Billy Bookcase Index – yes, that’s a thing – they cost most in Egypt, just over $100 (£79), whereas in Slovakia you can get them for less than $40 (£31).

Every three seconds, another Billy bookcase rolls off the production line of the Gyllensvaans Mobler factory in Kattilstorp, a tiny village in southern Sweden.

How Liquefaction Occurs During an Earthquake

liquefaction_demo With a little shaking, solid earth can behave like a liquid – heavy objects on the surface (e.g. buildings) sink, low density buried objects (e.g. fuel tanks) rise upward.
