Thunderstorms emit fluxes of gamma rays known as gamma-ray glows1,2, sporadically observed by aircraft1,3,4,5,6,7, balloons8,9,10,11 and from the ground12,13,14,15,16,17,18. Observations report increased gamma-ray emissions by tens of percent up to two orders of magnitude above the...

The results are presented as a function of velocity of primary ionizing particle in order to ...

Physical space is also an excuse for one of my favorite underused tropes: a character who carries more than one type of weapon. They might havea bow to use at range, a war hammer for big open spaces, a long sword for urban streets, and a dagger for cramped alleys. Not only does thi...
We know light travels at about 300,000 kilometres per second. That is 300 billion millimetres per second. How far will the first newly created light and gamma rays travel by the time the entire detonation process has completed? About 1.5 millimetres, or about a 16th of an inch. The whole...
We show that such jets can accelerate cosmic rays to high enough energies to produce high energy neutrinos. While the neutrinos stream out freely, the gamma-rays that accompany the neutrino production remain trapped inside the optically thick envelope. This explains the lack of observational ...
use those substances to detect onset and end of the fertile phase offemales," says Marlen Kücklich, lead author of the study, from the University of Leipzig and the Max Planck Institute for Evolutionary Anthropology. Therefore, in a second part of the study,odorsamples were presented to ...
by Yi Ruiqin and Albert Fahrenbach from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, Japan, has recently shown that a variety of compounds useful for the synthesis of RNA, are produced when simple compounds, combined with sodiumchloride, are exposed to gamma rays....

Mutation rates can be increased by many different means including temperature, long-term seed storage, tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g. cobalt 60 or cesium 137), neutrons, (product of nuclear fission by uranium 235 in an atomic reactor), Beta radiation...
