The simulated brain - "The scientists behind Blue Brain hope to have a virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to digitally simulate a brain accurately? Can it only be analog? And are there quantum effects to be considered? (previously 1 2 3 4) [more inside]

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]

Dorkbot is a "monthly meeting of artists (sound/image/movement/whatever), designers, engineers, students, scientists, and other interested parties who are involved in the creative use of electricity." Started in NYC in 2000 by Douglas Repetto, Director of Research at the Columbia University Computer Music Center as well as one of Wired's 10 Sexiest Geeks, there are now dozens all over the world. Past presenters have been featured here on the blue. For instance Jeff Han presented his multi-touch interface at dorkbot-nyc in April of 2006. Miru Kim presented her naked city spleen at dorkbot-nyc in October of 2006. Bummed that there's not one in your own city? Start your own! [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]

Biomimetics: Design by Nature. "Burs on a dog's coat led to the invention of Velcro. That's an example of biomimetics—the young science of adapting designs from nature to solve modern problems. Now it may be coming of age."

nanoHUB is an information goldmine, aimed primarily at scientists and engineers engaged under the broad umbrella of nanotechnology research, funded by the NSF, and based at Purdue University. Start with a series of nano tutorial lessons at the undergraduate or graduate level. Move on to seminars from top researchers on a variety of topics, or try some self-paced learning modules. Then run (real, useful) simulations in your browser. [some stuff requires free registration]

All the episodes of The Secret Life of Machines are available online. Created by engineer, artist, tinkerer and cartoonist Tim Hunkin, the show took a look at the science and mechanics behind common household objects, with a bit of social history, homemade laboratory experiments, and downplayed humor. The series grew out of a long-running strip, which Hunkin has now offers as his own cartoon encyclopedia. You can also try some experiments of your own, marvel at the coin-operated contraptions he made for the Under the Pier Show in Suffolk (don't miss the film), and read his thoughts about his brief foray into the fine art world and his ruminations about how art and engineering mix.

"In his talk... [Harvard President Larry] Summers also used as an example one of his daughters, who as a child was given two trucks in an effort at gender-neutral parenting. Yet she treated them almost like dolls, naming one of them 'daddy truck,' and one 'baby truck.'

"It was during his comments on ability that Hopkins, sitting only 10 feet from Summers, closed her computer, put on her coat, and walked out. 'It is so upsetting that all these brilliant young women [at Harvard] are being led by a man who views them this way,' she said later in an interview." Summers then responded with the currently in vogue non-apology apology.

Synthetic Trees could purify the air - "It looks like a goal post with Venetian blinds," said the Columbia University physicist...synthetic trees could help clean up an atmosphere grown heavy with carbon dioxide..."You can be a thousand times better than a living tree...There are a number of engineering issues which need to be worked out," he said. (BBC) Hurry up, then - "Ice dams are blocking Latvian ports, winds and storms are battering Europe, Portugal is freezing, Vietnam has lost one-third its rice crop, and the cold has caused close to 2,000 deaths in usually temperate South Asia."

Why the towers fell. PBS is airing a special episode of Nova about the science behind while the World Trade Center towers collapse. Nova's reputation for converting esoteric science & engineering into understandable explanations for the layman should make the show something to watch. 7PM EDT/PDT on most PBS stations. Set your Tivos.
