Early humans arrived in three waves, DNA study says

By ERYN BROWN July 14, 2012, 04:34 PM

Supporting a controversial view of how humans might have populated the Western Hemisphere, geneticists have found that groups from Asia traveled over the Bering Strait into North America in at least three separate migrations beginning more than 15,000 years ago -- not in a single wave, as has been widely thought.

Key results ahead for Alzheimer's drugs

July 11, 2012, 09:57 PM

What's next: We're about to find out if there will be a way anytime soon to slow the course of Alzheimer's disease. Results are due in about a month from key studies of two drugs that aim to clear the sticky plaque gumming up patients' brains. A pivotal study of a third drug will end later this year, and results from a small, early test of it will be reported next week in Vancouver, British Columbia.

What you need to know

July 05, 2012, 09:03 PM

If you want to make sure you'll still be able to use the Internet when you wake up Monday, go to www.dcwg.org, click "Detect," and follow the instructions from there. That's the website of the DNS Changer Working Group, set up by court order to fix a bunch of servers that had been taken over by an Estonian crime ring to redirect millions of users to rogue websites. The FBI took over the servers and cleaned them up, but it doesn't want to be in the business of running DNS servers permanently -- so it's shutting them down Monday.

It's like tryng to push your car off the road...

July 04, 2012, 08:40 PM

The idea of the Higgs particle was proposed nearly 50 years ago. It was discussed almost as a curiosity, to get around some inconsistencies between predictions and theory at the time in particle physics, that if an otherwise invisible background field exists, permeating empty space throughout the universe, then elementary particles can interact with this field.
