Often in class, I hear students asking teachers to go to the office and get some ibuprofen to get rid of a headache. Ibuprofen is such a common painkiller that we almost take it for granted. But scientists in the United Kingdom have been studying the effects of ibuprofen, and have come to realize that [...]

Robotic Gecko
May 31st, 2011 · 1 Comment · Chemistry
A Stanford mechanical engineer is using the biology of a gecko’s sticky foot to create a similar robotic model. The robot gecko has feet exactly like that of an ordinary gecko, which means it can virtually do anything a real-life gecko can do. It can climb vertical slippery walls just like a real gecko. After [...]

Stamping out Low Cost Nanodevices
May 31st, 2011 · 1 Comment · Chemistry
A new simple technique for stamping patterns which are invisible to the human eye onto a special class of nano material. This technique provides a cost-effective way to produce novel devices in areas from drug delivery to solar cells. It works because the materials that are riddled with tiny voids that give them unique optical, electrical, chemical and mechanical [...]

“Spooky Action at a Distance.”
May 31st, 2011 · 1 Comment · Chemistry
Physicists have been trying to develop over a many years to use a certain practice for absolutely safe data transmissions. A team of scientists have demonstrated that two remote atomic quantum systems could prepared in a shared “entangled” state located in two different facilities. The team realized that the building block for a quantum network consisting of [...]

Can Carbon Dioxide Be A Good Thing?
May 31st, 2011 · No Comments · Biology, Chemistry
A lot carbon dioxide can be bad, but sometimes it can be good for plants and trees. The more carbon we dump into the air, the faster forests and plants grow. This idea came from research done by the North American carbon program. Scott Denning is a physicist from Colorado State University in Fort Collins, Colorado. [...]

Nanowires Improve Computer Memory
May 31st, 2011 · 1 Comment · Chemistry
Studies recently conducted at the National Institute of Science and Technology and George Mason University could have revealed characteristics of a new and improved type of computer memory. Nanowires are composed of silicon wires that are extremely thin and packed together. These nanowires are being studied because they could potentially store data more efficiently and [...]

Battery-Less?
May 30th, 2011 · 1 Comment · Chemistry
Have you ever wanted to detect a certain type of chemical but just cant because of the battery? Well no more they have recently been experimenting with a newer device that works with out a battery. It instead reacts differently to different chemicals. No battery required! It makes use of nano wires, unexposed and exposed wires. The team has tested it with many different [...]

Tiger Sharks Dying because of Internal Bleeding
May 30th, 2011 · 2 Comments · Biology
Leopard sharks have been found dead on beaches. One was found dead due to internal bleeding. It was bleeding so much that the blood was coming out of its skin. Inflammation, bleeding and lesions were found in the brains of these sharks. Results of a test found that around 50 of the sharks that were [...]

Songbirds and their voices
May 30th, 2011 · 1 Comment · Biology
Not everyone may know this, but noise pollution also has its effects on wildlife. Birds rely on their songs to mark territory and to attract mates. When louder noises drown out the bird’s song, it can often alter its voice so it can be heard. Some birds can change the frequency of its voice so [...]

Low Vitamin D Linked to Child Obesity
May 30th, 2011 · 1 Comment · Biology
Vitamin D deficiency is common in America and is also linked to child obesity. Researchers tested the Vitamin D levels in 240 white and black, healthy and obese children. Most of them were Vitamin D deficient. Low levels of Vitamin D show that there is a higher body mass index level and a higher level [...]
