Tech Q&A: Chip security fix hurts some PCs

Q: On Jan. 8, my 10-year-old, custom-built Windows 7 PC crashed. (I got the "blue screen of death.")

Helpware: Mice that keep you healthy

In the early days of electronic pagination some 40 years ago, I worked for a newspaper that bought the first one on the market. It was a monster of a computer, with a screen that was more than 30 inches wide. The screen's resolution was awful. The monitor flickered anytime a task was performed. The mouse was about as big as a size-15 men's shoe ...Read more

Researchers have new evidence that animals are exquisitely vulnerable to the effects of warfare. They analyzed 65 years of armed conflicts in Africa and found that exposure to just one year of war within a...Read more

Mysterious series of fast radio bursts may have been twisted by extreme environment

Astronomers watching a fast-radio burst flashing from more than 3 billion light-years away say that its source lies in an extreme environment with a powerful magnetic field -- perhaps a supermassive black hole, or the remains of a supernova.

The findings about the phenomenon known as FRB 121102, described in the journal Nature and at the ...Read more
