Student Design Ecological, Portable Bug Trap
2008-03-23 03:10:00
Conventional insect traps may present health risks, besides the fact that they make noise or smell bad. Old bug catchers usually blow bugs into thousands of tiny pieces potentially containing colonies of bacteria that could spread inside the room and possibly infect human residents. They also can blow up particles containing small bits of ...

Why Does The Number 1 Appear So Frequently? Scientists Can?t Explain It
2008-03-23 03:10:00
Number 1 is very frequently used around the world. That wouldn’t be much of a curiosity, if you knew all the fields it appears in. It’s the most commonly found figure in groups as disparate as populations, death rates, physical and chemical constants, baseball statistics, the half-lives of radioactive isotopes, answers in a physics ...

Future Airliners: More Comfortable, Resistant and Made of Plastic
2008-03-23 03:10:00
It may take as little as ten years for the airplanes on long, international flights to be made more out of plastic than metal. The most modern aircrafts of today are made of aluminum, a light but strong material than can be easily obtained from natural compound. The airliners of tomorrow will be made of ...

Radical Engine Redesign Reduces Fuel Consumption by 20 Percent
2008-03-23 03:10:00
In a normal internal combustion engine, the movement of the pistons turns the crankshaft, which is linked to a camshaft that opens and closes the valves, directing the flow of air and exhaust into and out of the cylinders. A new computational model greatly increases the engine performance from one combustion cycle to the next ...

Metal That Remembers and Returns to The Original Shape
2008-03-16 06:26:00
Everybody knows that a piece of metal, once bent, is impossible to be reverted to its original state. But, a recent study revealed that, when heat is added to bent metal films having the right microstructure, the films return to their original shapes. The higher the temperature, the sooner the metal films revert. “It’s as ...

It is known that the Earth ’s molten metal core fuels a magnetic field. Now, a team has generated similar self-sustaining fields even when the flow is highly turbulent. The new approach is a closer simulation of the Earth’s dynamo than other experiments as the fluid flows freely in a large tank and is not channeled ...

Brightest Synthetic Fluorescent Particles Ever
2008-03-16 06:26:00
Fluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. Usually the absorbed photon is in the ...

Could Cold Fusion Be Possible ?
2008-03-16 06:26:00
In March 1989, cold fusion was brought into popular consciousness by the controversy surrounding the Fleischmann-Pons experiment, when “cold fusion” was hailed as a scientific breakthrough with the potential to solve the world’s energy problems by providing a virtually unlimited energy source. It was dismissed by some scientists as “bad” science due to alleged errors ...

Closer to Absolute Zero
2008-03-16 06:26:00
Absolute zero is the lowest possible temperature, occurring when no heat energy remains in a substance. It is the point at which molecules do not move (relative to the rest of the body) more than they are required to by a quantum mechanical effect called zero-point energy. By international agreement, absolute zero is defined as ...

World?s Largest Particle Accelerator Unveiled
2008-03-16 06:26:00
A particle accelerator is a device that uses electric fields to propel electrically charged particles to high speeds and to contain them. An ordinary CRT television set is a simple form of accelerator. There are two basic types: linear (in a straight-line) accelerators and circular accelerators. In a linear accelerator (linac), particles are accelerated in ...

Xenon and the Electric Breakdown
2008-03-16 06:26:00
An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, similar to the instant spark, resulting from a current flowing through normally nonconductive media such as air. An archaic term is voltaic arc as used in the phrase “voltaic arc lamp”. Whether it’s a lightning bolt or the spark inside ...
