Scientists are developing tiny magnetic particles called nanodots that are only a few billionth of a meter in diameter. The nanodots are showing promise in decreasing the amount of data storage space by at least one-hundred times what is currently held with hard disk drives. With storage requirements doubling about every year, nanodots may hold the answer to handling increasingly large amounts of digital data.

On January 11, 2007, at about 5:28 p.m. EST, China destroyed one of its aging weather satellites—Feng Yun (FY-1C)—with a ground-based, modified medium-range ballistic missile equipped with a kinetic kill projectile aboard—generally called an ASAT (anti-satellite) missile system.

Large Hadron Collider: Does every particle in the universe consist of points, strings, or loops?

For many years String theory has been a viable adjustment to the Standard Model of particle physics—a quantum field theory that cosmologists hope will unite all the fundamental forces of nature (weak, strong, electromagnetic, and gravitational). In other words, explain how the universe works. The problem so far has been that the Standard Model does not explain the gravitational force. And recently, String theory, without any experimental conclusions to back it up, has being challenged by other theories such as Loop Quantum Gravity.

NASA goes metric for Moon missions

Every country in the world has adopted the metric system for its units of measurements except for Liberia, Myanmar (formerly Burma), and the United States. The people of the United States tried to convert to metric—mostly in the 1960s and 1970s (remember metrification?)—but it failed miserably. However, to avoid confusion, minimize safety concerns, and support international cooperation, NASA has decided to use the metric units for all operations with respect to its new lunar initiatives.
