Muscle-Sensing T-Shirt Improves Athletic Technique

Lisa Zyga — Sat, 05 Jul 2008 19:57:46 -0700

As countless coaches have advised their athletes, often the best way to improve technique is to break things down into one movement at a time.

A new T-shirt that measures muscle output could take this strategy to the extreme. The shirt, which is embedded with small sensors, enables athletes to find out which muscles they're using at different moments, and how hard. The invention is part of the ConText Project.

Insects Use Plants as Telephones

Lisa Zyga — Tue, 02 Dec 2008 11:48:08 -0800

Some insects use plants as telephones, communicating with each other at opposite ends of the plant, researchers have found. Insects that live below ground and feed on a plant's roots send chemical signals via the leaves of the plant, alerting leaf-eating insects that live above ground that the plant is already occupied.

Flawed Fishing Policies Result in Fewer Fish

Lisa Zyga — Mon, 01 Dec 2008 12:06:07 -0800

In an effort to maintain a steady population of fish, many fisheries have rules for minimum fish sizes or weights. If the fish is too small, it must be thrown back to give it more time to grow and reproduce. Now researchers have found that this policy is flawed.

Scientists to Evolve Viruses to Death

Lisa Zyga — Tue, 11 Nov 2008 13:49:20 -0800

Evolution, by the very meaning of the word, is generally thought to be a process that slowly unfolds over time, without outside interference.

But now scientists from Rice University are trying to force certain viruses to evolve erratically, in an attempt to kill them. The technique is called "lethal mutagenesis," and while it may sound vicious, it could be a last resort of self-defense against contagious viruses that attack humans.

Sunscreen for Plants Could Increase Worldwide Crop Yields

Lisa Zyga — Mon, 03 Nov 2008 13:50:43 -0800

According to clean chemical company Purfresh, food growers lose between 20 and 40 percent of their crops every year due to sun damage, especially in water-limited regions. The company recently developed a kind of "plant sunscreen" rated at SPF 45 that protects crops from harmful UV and IR rays while permitting beneficial rays to reach the plants.

Buzz Aldrin: Mars Pioneers Should Remain Permanently On Mars

Lisa Zyga — Sun, 26 Oct 2008 18:33:42 -0700

A trip to Mars could take years and cost billions of dollars. If NASA and the European Space Agency are going to commit to such an ambitious endeavor, they should try to get the most out of their investment. That's why, according to astronaut Buzz Aldrin, the first Mars pioneers should stay there permanently.

Lisa Zyga — Tue, 09 Sep 2008 14:49:36 -0700

In response to the growing concern of light pollution in urban areas, researchers have developed a system that automatically measures light pollution and optimizes lighting design. This quantitative data is the first published information that the researchers know of showing how much light escapes from outdoor lighting installations.

Folding Light Could Lead to Tiny Cell Phone Cameras

Lisa Zyga — Fri, 05 Sep 2008 11:05:09 -0700

In a standard camera lens, light is focused onto a single point in order to magnify a scene. In telescopes, on the other hand, lenses work differently, by reflecting light back and forth to achieve greater magnification. This idea can also be thought of as "folding" light.
