NASA is preparing to launch an inexpensive, football-sized probe to study lightning, including its effects on the atmosphere and the possible link between the phenomenon and powerful energy bursts known as terrestrial gamma ray flashes.
Astronomers have long wondered exactly what the enigmatic jets given off by black holes are made of. Now, an international team of scientists, writing in the journal Nature, has apparently solved the mystery and discovered the composition of those high-speed beams of matter.
A new chapter has been opened in our understanding of the chemical activity of nanoparticles says a team of international scientists.
Whether it is diagnostic imaging, analysis of unknown substances or ultrafast communication – terahertz radiation sources are becoming more and more important. At the Vienna University of Technology, an important breakthrough has been achieved.
MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.
Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns out that all the red vases are intact and all the green ones are smashed to pieces?
Every day, all day, our DNA gets beaten up by chemicals and radiation -- but remarkably, most of us stay healthy. Now, an investigation by a team of French and Canadian researchers has produced insights into a little-studied but common radiation threat to DNA: low-energy electrons (LEEs), with energies of 0-15 electron volts.
This video and article explain how sudden exercise releases free radicals (loose electrons) in the body and how those electrons damage organs, tissues and can cause death.
Topology -- the understanding of how things are connected -- remains abstract, even with the popular example of doughnuts and coffee cups.
The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
