Sociologists at the AAAS annual meeting have reported that China is making major investments in nanotechnology. Their aim is to 'Leapfrog' past the United States in technological development by focusing on long-ranging scientific goals. So far, the Chinese government has poured about $400 million into the hot field of research. Considering the low cost of equipment and labor over there, that is a very large sum of money. Singapore and Russia have similar programs.

Scientists from Korea and the Czech Republic have discovered new drugs that can counteract the chemical overload caused by nerve gas. All of the experimental medications belong to a family of chemicals called oximes. Those molecules reactivate the enzyme that is damaged by the chemical weapons. Last year, the FDA approved the first combined atropine and oxime auto-injector for use by emergency personnel. Israel has been providing them to their citizens since the first Gulf War.

Psychologists at the University of Nebraska have read 300 threatening letters and 99 angry emails to members of congress. They concluded that the authors of the electronic messages show less signs of serious mental illness, but they are more profane and disorganized. The report was published in the September issue [subscription] of the Journal of Forensic Sciences.

Forty years ago, LOGO, a derivative of LISP, was born. Several years later, it became the cornerstone of educational software that simultaneously taught geometry and how to think like a coder. With a plethora of high-end educational software packages to choose from, each with flashy multimedia and trademarked characters, parents and teachers may find the humble turtle a bit outdated. Thankfully, several LOGO programs are available for free through a variety of websites, but perhaps 3D programming environments like Alice will be the wave of the future.

On the most recent edition of his new show, Dan Rather reported that the new 787 Dreamliner aircraft may be unsafe. Since then, dozens of news agencies have jumped on the bandwagon. Most of them are reporting that the carbon fiber frame may not be as sturdy as aluminum. Few have bothered to question Rather's claims that the composite materials are brittle, more likely to shatter on impact, and prone to emit poisonous chemicals when ignited. While there is a lot of weight behind the argument that composite materials are not as well-studied as aircraft aluminum, the reasoning behind the flurry of recent articles may be faulty. The very title of Rather's story, Plastic Planes, indicates a lack of grounding in science. Perhaps the greatest concern should be how well the plane will hold up to water. Because they are vulnerable to slow and steady degradation by moisture, the new materials may not last as long as aluminum. Testing them for wear and tear will be more difficult too.

Hollywood is not known for providing a wealth of positive female role models. Danica McKellar, the actress that played Winnie Cooper on The Wonder Years and Elsie Snuffin on The West Wing, has written a math book for teenage girls. Math Doesn't Suck is in the style of a teen magazine. It even includes a horoscope, cute doodles of shoes and jewelry, and testimonials from attractive young career women that use math at work. It focuses on fractions and pre-algebra and uses mnemonics like calling a reciprocal a "refliprocal", because you just take the fraction and flip it upside down. Wired interviewed McKellar about the new book and her crusade to eliminate the achievement gap between boys and girls in math courses. McKellar graduated Summa Cum Laude from UCLA. While studying there, she co-authored a proof and presented it at a conference. After she and Mayim Bialik — star of Blossom and a PhD in neuroscience — appeared in a 20/20 episode about intellectual actresses, several literary agents came knocking on her door.

In 2004, the FDA approved the cone snail venom ziconotide (Prialt) for the treatment of chronic pain. It is only used for severe cases because it must be injected directly into the spinal column. This month, researchers from the University of Utah have reported the discovery of a new snail venom with a completely different amino acid sequence. Because it very selectively attaches to and blocks nerve signals by binding to a particular type of acetylcholine receptor without causing any collateral damage, the newly discovered venom could also become a fantastic medical tool.

The Wired Science blog has production stills and a story about a side project that several Industrial Light and Magic employees have been working on. They are producing the short story Maelstrom II as an independent film. The entire thing was shot in front of a bluescreen so that all of the sets and props will be CGI. The lone actor, Chuck Marra, plays a guy that hitches a ride on an electromagnetically launched freight capsule from the moon to earth. When the nuclear reactor that powers the catapult fails, he is thrown into space, but not far enough to escape lunar gravity — leading to an Apollo 13 style rescue mission. The original story was written by Arthur C. Clarke, author of 2001: A Space Odyssey.
