Girls sweep Siemens science competition for US high schools

For the first time in history, the Siemens Competition, formerly the Siemens-Westinghouse Competition, was won by two females. The competition, which along with the Intel Competition are one of the two most prestigious competitions for high school science research in the United States. The Siemens Competition has two competitions, one for individual research and the other for team research. For the first time in history both the individual and team awards were won by women.

Drug-resistant staph deaths surpass AIDS in the United States

Methicillin-resistant staphylococcus aureus (MRSA), a drug-resistant strain of bacteria, killed nearly 19,000 Americans in 2005 alone, according to a new study in the Journal of the American Medical Association. That is more people than were killed by AIDS in the United States. More than 194,000 Americans were afflicted with MRSA infections in 2005. Although the supergerm, or superbug, is primarily found in hospitals, a growing number of cases have been contracted at public gyms and schools. In...

US scientist says he created first 'artificial life form'

According to reports, American biologist Craig Venter is going to announce that he has created the first ever "artificial life form" on Earth at the J. Craig Venter Institute, a U.S. laboratory and research center, using synthetic chromosomes made from chemicals. The Guardian Unlimited reports that Venter may announce the discovery on Monday, but could publish the report within a few weeks. "[This is] a very important philosophical step in the history of our species. We are going from reading...

NASA says star system contains 'earth-like planet' in the making

NASA scientists have stated that an "earth-like" planet is currently forming in a star system's 'habitable zone' just over 400 light-years from Earth. The new discovery was made by NASA's Spitzer Space telescope. According to scientists, dust and rock orbiting a 10 million year old star in the system HD 113766 contains "enough [material] to build a Mars-size planet or larger." "The timing for this system to be building an Earth is very good. If the system was too young, its...

Cell Phones And Brain Tumors

The use of cellular phones has increased rapidly during the late 1990’s. On that period, newer wireless communication technologies have emerged. Currently, According to CTIA - The Wireless Association, cellular phone owners in U.S have reached to 194.5 million which captured over 65 percent of total U.S. Population. However, there are several issues being discussed to asses the safety implications of mobile phones to human health. For many users, a new finished study was published online in the...

When Asphalt and Dinosaurs Roamed the Earth

You may not be aware of it but a part of the highways and parking lots that you drive your car into may have been around for millions of years! Those roadways and pavements considerable history can be attributed to one if its key component: asphalt. Yes, the asphalt that is used to pave the roads that you drive through has indeed been around since the prehistoric times to merit a discussion. Asphalt has been dated back as early as the prehistoric period. Evidence of this claim can be...

Fast evolution observed in butterflies

Scientists reported that they had documented very fast evolution in the butterfly species Hypolimnas bolina. After infection by Wolbachia, the fraction of the population that was male dropped drastically to about 1% of the total population. However, after approximately ten generations (about a year) the male population had rebounded to about 39% of the overall population. In the case of H. bolina, infected females were unable to have male offspring since the male embryos died early on....

The History of Tornadoes and Hurricanes

While the numbers of hurricanes and tornadoes have increased since 1994, there are no clear signs that this is a worldwide trend. Many people have argued that the increasing number of hurricanes and tornadoes are a result of global warming, but as of this time, there is not a lot of scientific evidence to support this. The aspect of these storms which is universally agreed upon by everyone is that they have become much more expensive. Photoshop can also be used to create tornado and hurricane...

The History Of Wind Generated Power

With the increased costs of energy derived from fossil fuels, many consumers are interested in alternative sources of energy. Unfortunately the market trend tells us that little to no relief in oil prices is in sight. A great source of power can be harnessed from the wind using electricity generating windmills. Below is a brief history of wind power, and how it came to be. Wind power has been harnessed for many, many years. Nobody knows for sure when man started using the wind's power to grind...

NASA readies Mars lander for launch

NASA technicians are beginning final launch preparations on the Phoenix Mars Lander spacecraft destined for the planet Mars. The unmanned spacecraft is scheduled to launch from Cape Canaveral Air Force Station on Florida's east coast on August 3, at around 5:35 a.m. EST (9.35 UTC). Phoenix will land in the Red Planet's northern polar region to search for signs of life, and analyze the Martian climate from a polar perspective. The launch period for Phoenix extends from August 3, 2007 until...
