The Hawaiian Islands represent a wide diversity of ecosystems and environments, including areas of breathtaking natural beauty as well as densely populated coastal cities. These unique environments are already changing under the influence of climate change from the effects of increasing temperatures, decreasing rainfall, rising seas, coastal erosion, land use and development changes, and increasing demands on our natural resources

(Phys.org) —Examination of one of the Almahata Sitta meteorites (aka, ALM-A, found in Sudan in 2008) by a team of space scientists working in Germany has revealed a volcanic past. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they dated the meteorite to just a few million years after our solar system was born and uncovered evidence that it suggests it was produced by volcanic activity.

The Russian news agency ITAR-TASS is claiming that Russian officials have confirmed that Russian cosmonauts have found sea plankton on the outside of the International Space Station. The news agency reports that the cosmonauts have also found traces of other organisms on the outside of the station as well.

Introduction Using MPEG Layer-3 compression, 40 MByte audio files have been compressed to approximately 3.5 MBytes. With the wide availability of MP3 files via the Internet, portable MP3 players have become increasingly popular. MP3 players are currently available that utilize either Compact Discs, SmartMedia, Compact Flash, or a hard-drive as their storage medium. Our interest […]

When a colony of honeybees grows to about 4,000 members, it triggers an important first stage in its reproductive cycle: the building of a special type of comb used for rearing male reproductive, called drones. A team of experts from the Department of Neurobiology and Behaviour at Cornell University, led by Michael Smith, studied what starts the reproductive cycle of honeybee colonies

Introduction: Our ECE 476 Spring 2002 final project is a musical synthesizer that mimics the sounds produced by a piano and a clarinet.  We wanted to create a device that could produce different musical signals by direct digital synthesis.  Using Fourier analysis of the signals, we were able to imitate the sounds from different musical […]

Introduction For years scientists and scholars alike have been plagued by one common obstacle which, until now, has proven to be impossible to overcome.  How do you find the country you want on a globe?  Sure, the easy answer is to just use the longitude and latitude coordinates, but really, that’s quite confusing.  Some may […]

Researchers are reporting new discoveries about how militarization affects the general, civilian population, and the biggest positive impact is adequate sanitation and access to education. The research led by Steve Carlton-Ford, professor and head of the University of Cincinnati Sociology Department, was presented at the 109th meeting of the American Sociological Association in San Francisco.

Introduction With all focus of computer technology advancement placed on processors and memory, sometimes the most simple of components are overlooked.  This is especially the case with the mouse, a device that has changed very little since its conception by Xerox.  It still retains its basic shape and function in moving a cursor within a […]

A convergence of factors is propelling a market rollout of the hydrogen fuel cell vehicle, according to a new study from the Institute of Transportation Studies at the University of California, Davis. A key to hydrogen’s potential success is a new smart solution that clusters hydrogen fuel infrastructure in urban or regional networks, limiting initial costs and enabling an early market for the technology before committing to a full national deployment, suggests the study.
