It is believed that protons of energies exceeding 50 MeV are the result of the beta decay of neutrons created by cosmic ray collisions with nuclei of the upper atmosphere. The source of lower energy protons is believed to be proton diffusion due to changes in the magnetic field during geomagnetic storms.
Next-generation DNA sequencing has the potential to dramatically accelerate biological and biomedical research, by enabling the comprehensive analysis of genomes, transcriptomes and interactomes to become inexpensive, routine and widespread, rather than requiring significant production-scale efforts.
We travel and only sometimes seem to arrive, the longest journey our ultimately unknowable destination. The only thing that remains for us is to observe the winds and currents which hinder or assist our passage.
Learning the language of modern art is like renting a room in a foreign city. If you don’t know what the questions mean, you might end up in the basement. If you know what the questions mean, you might choose the basement anyway.
