The technology behind the Arena X-Glide

Recently, the new Arena Powerskin X-Glide® was named one of the top 50 inventions of 2009.  This swimsuit utilizes various forms of technology to give the swimmer as many advantages as possible. Unlike other racing suits, it uses a full polyurethane coating, giving it the advantage of reduced friction. This coating also traps air, increasing the buoyancy of the swimmer and reducing drag. Underneath this coating, there are two layers – one layer of titanium alloy and a layer of Read more…

What are tachyons?

Tachyons- A class of particles proposed in the late 1950’s by physicist Arnold Sommerfeld, which are thought to travel faster than the speed of light. All light travels at approximately 2.99792468 *108 meters per second - an increasingly high speed so intense that it would take one-tenth of a second to travel around the world at the equator. As a result, people often question the origins of such a large speed, and in order to understand tachyons, one needs to Read more…

The Vision of a Hammerhead

Ever wondered what evolutionary benefit could possibly arise from having a T-shaped head? Well, the hammerhead shark can certainly attest. In a recent study on hammerhead sharks at Florida Atlantic University, team study member Michelle McComb found that hammerhead sharks had amazing peripheral vision. Michelle’s team performed lab tests on different varieties of sharks that included sweeping a light in various arcs around the shark’s head and measuring electrical activity in the eye. What they found was that the hammerhead Read more…

Bless You: What nosey scientists have unearthed about the secrets of sneezing

“ACHOO” is more than just the sound made when sneezing; it is actually the acronym for the Autosomal-dominant Compelling Helio-Opthalmic Outburst syndrome, in which one sneezes upon sudden exposure to bright light. When people think of sneezing, the most common causes people relate it to are colds or irritations in the nose, such as pepper.  This is logical, considering the function of a sneeze (also known as a sternutation) – to cleanse the nasal passages by expelling foreign particles through Read more…

Will Copenhagen Count?

The impending Climate Change Conference that is scheduled to start December 7th in Copenhagen has created quite a stir internationally. With over 190 nations planning to attend (almost every nation in the world will be represented), along with various non-governmental organizations, the United Nations has raised the stakes concerning global climate change. Unfortunately, the barrage of references to the gathering in Denmark has allowed the public to tune out mentions of the meeting as simply white noise. Ironically, the media Read more…
