During the July 4th weekend of 1994, while riding in a 1988 Chevy Blazer with his wife at the wheel, a computer engineer named Jeff Bezos laid the groundwork for a retail revolution. Back then, the Internet was an insider's tool, largely limited to government and academic circles

Scientists calculate that a "perfect lens," a slab of artificial material engineered to focus electromagnetic fields in ways that natural materials can't, may increase the efficiency of some wireless power transfer systems.

(PhysOrg.com) -- The past decade has seen the emergence of the field of spintronics, aimed at increasing the efficiency of information processing and computer memories. The idea behind spintronics is to harness the magnetic property of the electron, referred to as its spin. This property can then be used, in addition to the electron charge, for increasing the functionality of the semiconductor computer chip, in terms of its capacity to store and process information.

Robot Fly Trap A professor at the University of Maine has made a robot version of a plant that in some ways is a robot all by itself...the Venus Fly Trap. The diminutive fly-grabber is partly made of a nanomaterial called ionic polymeric metal composite, which acts to replicate the tiny sensitive hairs inside a real trap that send a signal to the closing mechanism when stimulated by a fly landing inside--in this case the nanomaterial, when flexed, sends a tiny electrical signal through an amplifier to the two "leaves" of the trap, made out of the same material. When the bigger signal hits the leaves, they flex in reaction...and trap the fly.

Using an engine design that was largely abandoned after World War II, new engines find fuel savings where big auto companies--weighed down by the inertia of their designs--can't. Decades of refining today's automobile engine technology has come to this: We're investing more and more, but getting less and less in terms of efficiency, performance, and durability
