As physicists gather in early August to celebrate a century since the initial discovery of cosmic rays, Alan Watson, emeritus professor of physics at the University of Leeds, explains how physicists have gradually revealed the nature of these mysterious objects and examines the progress being made in understanding where they come from.
It is now widely accepted that cosmic rays are the nuclei of atoms, from the entire range of naturally occurring elements, that travel at near-light-speeds for millions of years before reaching Earth. However, identifying the source of cosmic rays has proved to be a very difficult task.
Why are women's looks so often a topic of fascination — and criticism — even among women themselves? We seem so ready to judge the choices our fellow sisters make, from how we handle our relationships, children and careers, to how we deal with our aging appearance.

Following an exercise plan can ease depression in patients with heart failure, creating improvements in mood that are comparable to the effects seen with medication, a new study found.
Concussions and even lesser head impacts may speed up the brain's natural aging process by causing signaling pathways in the brain to break down more quickly than they would in someone who has never suffered a brain injury or concussion.
The earliest unambiguous evidence for modern human behavior has been discovered by an international team of researchers in a South African cave…
Although 75,000-year-old evidence for human innovation has previously been found in southern Africa, the meaning of these artifacts has been difficult to interpret.
