Science! (autoplaying video) The 42nd season of "Sesame Street," which premiered today, will be including a few new educational categories for preschoolers in its usual mix of lessons and parodies: STEM skills — Science, Technology, Engineering and Mathematics. In addition to more scientifically accurate slapstick, characters will try experiments, build bridges and boats, launch rockets and think through problems that require trial and error, observation and data -- all problem areas for America's students.

In February 2011, every teacher in Providence, Rhode Island was pink slipped. Not all 1,926 of them got fired, of course, but with the district facing a $40 million deficit, anything is possible. The district says it needs flexibility, just in case. Every school district in the United States faces its own version of what’s happening in Providence. However, “IMAGINATION: Creating the Future of Education and Work” is focused not on how we got here but rather how we can move forward from here immediately even as the education system continues to struggle.

Saturday August 27 Bill Nye dedicated a solar noon clock he designed. The clock is embedded in the facade of Rhodes Hall. At Solar Noon, when the Sun culminates, that is, reaches its highest point in the sky, the sun-shaped feature will light up. It is the marrying of mechanical and electrical engineering with astronomy. What could be better?

Ever made an indie action film and needed something for that epic glass-break scene? How about the blackest black you can find? Want to adjust your boots so that they are mud repellant? Inventables has everything you need - for the budding inventor, busy set designer, or Q in training.
For a number of years now work has been proceding in order to bring to the crudely conceived idea of a transmission that would not only supply inverse reactive current for use in unilateral phase detractors, but would also be capable of automaticaly synchronizing cardinal grammeters. Such an instrument is the turbo encabulator. [more inside]
Stephen Biesty is an award-winning British illustrator famous for his bestselling "Incredible" series of engineering art books: Incredible Cross-Sections, Incredible Explosions, Incredible Body, and many more. A master draftsman, Biesty does not use computers or even rulers in composing his intricate and imaginative drawings, relying on nothing more than pen and ink, watercolor, and a steady hand. Over the years, he's adapted his work to many other mediums, including pop-up books, educational games (video), interactive history sites, and animation. You can view much of his work in the zoomable galleries on his professional page, or click inside for a full listing of direct links to high-resolution, desktop-quality copies from his and other sites, including several with written commentary from collaborator Richard Platt [site, .mp3 chat].

The internet is full of answers, and some of them might even be true. For almost 20 years, the the Newton BBS has been a source of answers to science questions that may be accessed directly via the Web
as well as through telnet (no public telnet access any more, sorry). The Newton BBS "Ask A Scientist" archive has answers from 15 science fields, from astronomy to zoology, for a total of more than 20,000 questions answered. This was covered previously, and the site is aimed at teachers and students from grades K-12, so io9's Ask a Physicist questions (with answers from Dr. Dave Goldberg) might be more engaging.

iPhone 4's reception woes, wherein bridging the area where the metal bands meet (affectionately dubbed "the spot") results in a dramatic loss in signal strength, have been widely covered in the media over the past few weeks. Apple acknowledged the concerns publicly with a letter to customers where they concluded that the issue was not with the phone, but rather that they were being too generous in the way the software communicated signal quality as bars. After an update to iOS, the bars are in fact different but the problems persist. Most recently, Consumer Reports stated it was unable to recommend iPhone 4 because of the significant design flaw, despite listing it as the highest rated overall smartphone they've tested to date. The latest wrinkle in the story has been an open letter to Steve Jobs from Chuck Schumer, yes -- United States Senator from New York Chuck Schumer, in which he questions the adequacy and transparency of Apple's response to customer concerns. Apple will be holding a press conference at 10AM tomorrow in San Francisco to address the matter. [more inside]

Value engineering (also known as Value Analysis) is an approach to cost-effective product development that seems to have had its heyday in the developed world. However, as this recent student project "Value Engineering Project (Tata Nano)" seems to show, it is still popular in the developing world. Comparing this definition of Carlos Ghosn's now famous phrase "Frugal Engineering" with VE's seems to imply "new name; same approach" - understandable since Tata are the leading lights of the Indian Value Engineering society. Is it time for a global revival of interest?

For 36 years, engineering students from colleges across North America (and beyond) have aspired to succeed at winter's most prestigious, most arduous, most ridiculous challenge - to build and ride the world's fastest sled . . . made of concrete. Tomorrow, if you're in the greater Hamilton Ontario area, you can witness the Great Northern Concrete Toboggan Race yourself. Expect to see
- teams of five ride 150 kilo. sleds to speeds above 60 kph
- costumed revelry, not always appropriate for the weather
- exemplary standards of professional decorum
Audiophoolery: Pseudoscience in Consumer Audio. You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

Asian Carp update: since 2003(previously), the inexorable advance of Asian Carp up the Mississippi delta has brought them to within 6 miles of Lake Michigan. These invasive "100-pound Zebra Mussels" suck rivers clean and starve native fish. Asian Carp are now 97% of the fish biomass in the Mississippi delta. The "electric fence" across the canal didn't stop them. The poisoning of the canal won't stop them. Closing the Chicago sewage canal locks is the only way to be sure. But the Army Corps of Engineers have the jurisdiction. Feel safe? [more inside]

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."
