New industry alliance launched to promote use of IP in networks of smart objects

September 22, 2008

A group of leading technology vendors has formed the IP for Smart Objects (IPSO) Alliance, whose goal is to promote the use of the Internet Protocol (IP) to connect “smart objects” in the physical world that transmit information about their condition or environment, ranging from automated and energy-efficient homes and office buildings, factory equipment maintenance and asset tracking to hospital patient monitoring and safety and compliance assurance.

New Graphene Transistors Show Promise

March 6, 2007

Researchers at the University of Manchester have announced a single-electron transistor made out of graphene, a single sheet of graphite only one atom thick.

The researchers’ device, which is the first single-electron transistor to operate at room temperature, offers evidence that graphene is a promising alternative to silicon.

When most metals are shrunk to the size of quantum dots–about two to three nanometers wide–they become fragile and move… read more

Digital Paper Makes Device Debut

April 27, 2004

Sony, Philips, and digital paper pioneer E-Ink have announced Librié, an electronic book reader the size of a paperback book that can hold 500 documents in memory and allow owners to download new content. The display has a resolution of 170 pixels per inch, comparable to the print quality of newspapers.

Mind Over Mass Media

Robot Sex

May 6, 2004

The more robots interact with us humans, the more important their apparent gender becomes because it will make robots more compatible with their human masters.

Such thinking is behind a growing movement in robotics by Cynthia Breazeal and others to build machines that portray emotions.

The Internet IS a Series of Tubes: Real-Time Mapping of the London Underground

CPR: Mouth-to-Mouth Not Much Help

March 19, 2007

For adults who suddenly collapse, CPR is more effective if rescuers focus on chest compression over mouth-to-mouth ventilation.

By interrupting lifesaving chest compressions, mouth-to-mouth resuscitation may do more harm than good.

See_Me_a

DARPA wants to build inexpensive, “disposable” satellites for timely overhead imagery.

It’s seeking expertise from mobile phone, medical pneumatics, industrial machinery, optics, and automobile racing communities

DARPA’s SeeMe program (Space Enabled Effects for Military Engagements) aims to give mobile individual U.S. warfighters access to on-demand, space-based tactical information in remote and beyond-line-of-sight conditions.

If successful, SeeMe will provide small squads and individual teams… read more

Globe Grows Darker as Sunshine Diminishes 10% to 37%

May 13, 2004

Instruments around the world recorded a drop in sunshine reaching the surface of Earth, as much as 10 percent from the late 1950′s to the early 90′s, or 2 percent to 3 percent a decade.

In some regions like Asia, the United States and Europe, the drop was even steeper. In Hong Kong, sunlight decreased 37 percent.

Pollution dims sunlight in two ways, scientists theorize. Some light bounces… read more

Discovering the Virtues of a Wandering Mind
