Alpha particle therapy, such as diffusing alpha-emitters radiation therapy (DaRT) and targeted alpha-particle therapy (TAT), exploits the short range and high linear energy transfer (LET) of alpha particles to destroy cancer cells locally with minimal damage to surrounding healthy cells. Dosimetry for DaRT and TAT is challenging, as their radiation sources produce mixed radiation fields of α particles, β particles and γ rays. There is currently no dosimeter for real-time in vivo dosimetry of DaRT or TAT. Metal-oxide-semiconductor field-effect transistors (MOSFETs) have features that are ide...

IMAGINE an atom: like a miniature solar system with the nucleus in the centre and electrons orbiting around like planets.  Although the picture is familiar, analogies like this can mislead. New research published in Science last week by a team largely based in Darmstadt, Germany, emphasises that the atom is far stranger than our simple images. We still have much to learn about its inner citadel: the nucleus.  The discovery of the atomic nucleus is a little over a century old. Earlier ideas about the atoms imagined them like tiny billiard balls.  Then, in the early 20th century, the atom wa...

>> yeah. >> so for example, i'm not saying this is the answer, i'm just saying for example. there is a company trying to do very, very hot fusion. this is not cold fusion. this is very hot fusion. since i was a kid, since i was in engineering school, people have been trying to do fusion by shooting a beam of hydrons. that has an extra nutron. it has not worked. these people have boron and hydrogen. >> you just happened to have that laying there. >> i just have it. to produce the three alpha particles, the same alpha parts that we get inside the sun. and they believe they can do it for $30 bill...

Iraqi tanks didn't stand a chance against these sophisticated munitions dug rocky and his unit worked to selvage us armored vehicles that had been contaminated through exposure to depleted uranium we collected it all together we buried a lot in the desert and we shipped a lot back to the united states have been took over three years of cleanup. later some allied soldiers began showing symptoms of what would later be called gulf war syndrome. the depleted uranium becomes dangerous only after the munitions hit their targets and the toxic material is released into the environment the d.-u. partic...
