Is the PSA test helpful for men without symptoms of prostate cancer?
It is unclear.
But Heather Chappell, senior manager of cancer control policy at the Canadian Cancer Society, interpreted the research differently, saying the impact of PSA testing on mortality was only "marginally significant ... on the cusp of happening by chance," and that the risks are greater than for other forms of screening.
Bob Shiell, president of the Canadian Prostate Cancer Network, was far more unequivocal, saying the new findings are a ringing endorsement of screening and he hopes they will encourage more men to get tested.

Why did the dinosaurs die out?
The dinosaurs died out because of a single meteorite or asteroid impact.
Researchers now recognize five earlier cataclysmic events in the Earth’s prehistory when most species on the planet died out, the last being the Cretaceous-Tertiary extinction event 65 million years ago, which may have been caused by a giant meteorite striking the Earth, and which saw the disappearance of the dinosaurs.
In a paper published today in the influential science journal Nature, William Bottke and colleagues argue that a chunk of asteroid that broke off from a collision in the innermost region of the asteroid belt encountered a gravitational pull that drew it toward Earth over a period of tens of millions of years, eventually smashing into the Yucatan Peninsula, forming the Chicxulub crater and likely causing the extinction of the dinosaurs.
It is now widely accepted that the impact of a 10-kilometre-wide asteroid 65 million years ago coincides with the disappearance of the dinosaurs along with most of the animal species on Earth at the time.

How many Jews died in the Holocaust?
5 to 6 million Jews died in the Holocaust.
It has had some of the very crudest and most insensitive exercises in the history of so-called protest, of which I will cite only “the Holocaust on your plate” campaign, which, in my judgment, reached the level of a blasphemy against the memory of the six million Jewish people exterminated in Hitler's death camps.
