I seem to be missing something when I read articles that refer to the immense pressures at Earth’s core. If the source of gravity is mass and there’s equal mass in all directions at the core, then the core should be suspended in zero gravity. It’s very frustrating for me to get this wrong. Glenn […]

Hanging around Mom’s web helps everybody
For nearly grown spiderlings, lingering in their mother's web instead of setting off on their own turns out to be a boon for the mom, as well as themselves.

Reading this article, I wondered about other species. I have a golden retriever that licks her legs to the point of making them raw. I had thought it was a nervous habit learned as a puppy, then a previous golden retriever owner told me that it is a trait of the breed. I am now […]

Ancient Gene Takes Grooming in Hand
A gene involved in body development also plays a critical role in regulating the grooming behavior of mice, a discovery that may advance the understanding of certain psychiatric disorders.

Electrons grab unexpected energy share
When atoms or molecules react with a metal surface, even briefly, they can inject much more energy into surface electrons than previously realized.

Liquid computer takes key quantum step
The first, rudimentary implementation of a method, called Shor's algorithm, for using quantum mechanics in computations suggests that larger-scale implementations are possible and may eventually break the codes used today to protect secret messages on the Internet and elsewhere.

Finding fault for an old earthquake
Scientists in Southern California believe they've found evidence that finally identifies the source of one of the region's largest quakes, a magnitude 7-plus temblor that struck the area on Dec. 21, 1812.

Satellites could help track sea level
Experiments that used signals from Global Positioning System satellites to precisely measure altitude above a lake's surface may pave the way for fleets of spaceborne sensors that can quickly and inexpensively monitor local and global changes in sea level.
