Leaves from the lotus plant have an ability to repel nearly all the rain and dew that hits them. Scientists who want to make new waterproof materials are beginning to look at them. Chuan-Hua Chen and his team from Duke University have created a material that repels water like the lotus plant. They took high speed videos that [...]

Tungsten Ions May Diagnose Fusion Energy Reactors
October 29th, 2009 · No Comments · Chemistry, Physics
Ordinary sodium gas radiates bright yellow-orange light which scientists have termed the “D” spectral lines. Tungsten ions emit intense light in analogous “D” spectral lines, but they have higher energy levels.Measuring the wavelengths and relative intensities of lines in the spectrum of light released by a population of tungsten ions in the plasma can provide [...]

Lasers Generate Underwater Sound: Potential For Naval And Commercial Underwater Acoustic Applications
October 29th, 2009 · No Comments · Physics
In this article I discovered that if you have a good conversion of light into sound can be achieved by concentrating the light sufficiently to ionize a small amount of water, which then absorbs laser energy and superheats, which then becomes a small explosion of steam, which can generate a 220 decibel pulse of sound.

Harvesting Energy from Natural Motion: Magnets, Cantilever Capture Wide Range of Frequencies
October 28th, 2009 · 1 Comment · Physics
Energy Harvesting is essentially converting one type of energy, like the motion of wind, to another type of energy, like electricity. For example: in a “wind farm” wind blowing through the area causing giant propellers to turn. Because the propellers are turning it creates energy which can be converted to energy. Some propellers are also [...]

Light From Black Holes
October 28th, 2009 · No Comments · Uncategorized
As far as most people know, black holes are the darkest things out there. Their gravity is so intense that not even light can escape their grasp. Black holes aren’t studied with telescopes, but with computers, because you really can’t see them. Black holes might not be as dark as we thought though. Gases being [...]

Pumpkin Skin May Scare Away Germs
October 28th, 2009 · No Comments · Biology
Recently scientists have made and extraordinary discovery which is that pumpkin skin in fact scares away infectious diseases in yeast. Scientists took a closer look at the pumpkin skins to observe that Candida albicans (C. albicans) fungus causes vaginal yeast infections, diaper rash in infants, is not toxic to the pumpkin skins this could lead [...]
Tiny but adaptable wasp brains show ability to alter their architecture
October 28th, 2009 · 1 Comment · Biology
These wasp have a brain about the size of two grains of sand. so there must be alot of power packed into such a small brain. When these wasp are young, there job is inside the hive. Then they get aliitle older and they move farther out of the hive and eventualy outside the hive [...]

Rot-resistant Wheat Could Save Farmers Millions
October 28th, 2009 · 1 Comment · Biology
This article is about a fungus called Crown Rot, whicheats through wheat and barley. This fungus normally eats through about $79 million a year. Because of this scientists and farmers are trying to develop a rot resistant crop. Not only will it stop crop loss, but it will lessen some sicknesses that this rot produces. [...]

A Fifth State of Matter?
October 28th, 2009 · No Comments · Physics
“Physicists at the University of Alberta, in Edmonton, Alberta, Canada, have made a major advance in the understanding of what appears to be a new state of matter.” At very low temperatures, helium gas turns into a liquid. Put under extreme pressure the liquid turns into a solid. Physicists have been manipulating solid helium so [...]

FASTER COMPUTERS?
October 28th, 2009 · No Comments · Uncategorized
team of French physicists say they have used a femtosecond laser (ultra-fast bursts of laser light) to alter electron spin and this would speed up retrieval and storage. The technique could increase the speed up to 100000 times. imagine the possibility to be able to surf the net even faster computer work and computer operated [...]
