Staying Out of a Jam: Air Force Looks at Nanotube Sheets for Electromagnetic ShieldingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Aerospace and aircraft companies as well as the military have been challenged to find ways of effectively shielding sensitive electronic equipment such as radar and radios from electromagnetic interference (EMI) without adding a lot of weight to aircraft and satellites (the more massive they are, the more fuel they need to stay in the air or achieve orbit, respectively). Whereas EMI can lead to headaches like erased data and loss of connectivity for casual computer and cell phone users, the problem is far more serious in aircraft, where interference can jam cockpit radio and radar signals, preventing pilots from sending an...

Research in a Vacuum: DARPA Tries to Tap Elusive Casimir Effect for Breakthrough TechnologyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Named for a Dutch physicist, the Casimir effect governs interactions of matter with the energy that is present in a vacuum. Success in harnessing this force could someday help researchers develop low-friction ballistics and even levitating objects that defy gravity. For now, the U.S. Defense Department's Defense Advanced Research Projects Agency (DARPA) has launched a two-year, $10-million project encouraging scientists to work on ways to manipulate this quirk of quantum electrodynamics.

Turbocharging the Brain--Pills to Make You Smarter? (preview)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The symbol H+ is the code sign used by some futurists to denote an enhanced version of humanity. The plus version of the human race would deploy a mix of advanced technologies, including stem cells, robotics, cognition-enhancing drugs, and the like, to overcome basic mental and physical limitations.The notion of enhancing mental functions by gulping down a pill that improves attention, memory and planning--the very foundations of cognition--is no longer just a fantasy shared by futurists. The 1990s, proclaimed the decade of the brain by President George H. W. Bush, has been followed by what might be labeled “the deca...

Our deep need to delve into how things began is the inspiration for a new academic initiative. Scientific American columnist ( Critical Mass , which begins with the September 2009 issue) and theoretical astrophysicist Lawrence M. Krauss, head of the Origins Initiative at Arizona State University, organized the first Origins Symposium, held in April 2009. The event drew 80 scientists from a variety of disciplines, many of them Nobel Prizewinners. We asked Krauss to describe the results of the symposium.

Drug-Dispensing Contact Lens Could Replace Imprecise Eye DropsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Eye drops often provide quick relief to those suffering from minor eye problems such as redness, itching and dryness, but doctors have found that such dollops of medicine do not work very well for more serious conditions such as glaucoma, chronic dry-eye and corneal ulcers. Help may be on the way for those suffering from these or other ocular ailments in the form of a contact lens that sandwiches medicine between two layers of polymer film and administers large doses of medication at constant rates over extended periods.

When two of us (Langer and Vacanti) last wrote in this magazine 10 years ago about prospects for tissue engineering, the very idea that living flesh could be “constructed” by following engineering principles and combining nonliving materials with cells sounded fantastical to many. Yet the need for such transplantable human tissues to replace, restore or enhance organ function was, and remains, urgent. Today nearly 50 million people in the U.S. are alive because of various forms of artificial organ therapy, and one in every five people older than 65 in developed nations is very likely to benefit from organ repla...

It is easy to imagine how frightening this condition must have been before we had modern medical facilities for monitoring heart rate and for addressing anomalies. How can you effectively treat a condition without the means to understand the nature of the problem or the impact of your treatment? You clearly cannot and it would be folly, if not downright dangerous, to undertake the remediation of a condition that y...

I Know That Nose When you’re trying to recognize a face, the first thing you look at is the nose--whether you know it or not.

They found that most people look first just to the left of the nose, then to the center of the nose, then to the eyes. The first look was enough for people to recognize a face more than half the time, the second look increased accuracy, but the third did not--those two glances at the nose were enough. The researchers speculate that glancing at the center of the fa...

Amnio Alternative Amniocentesis and other prenatal tests designed to assess fetal health carry a small risk of miscarriage.

The fetal DNA, which tends to be shorter than that of the mother, is duplicated and subjected to a “molecular counting” technique that tallies b...

Although deaths from some specific conditions have gone up, overall mortality from cancer is on the decline for both men and women of almost all ethnic groups, as it has been since the early 1990s, in large part because of a shrinking t...
