Staying Out in Front

April 25, 2005

A published road map for the semiconductor industry has the smallest distances between wires on a memory chip shrinking from 90 nanometers today to 65nm in 2007, to 45nm in 2010, to 32nm in 2013 and on down from there.

HP hopes to apply some of its research ideas toward the 32nm milestone. The idea isn’t to replace silicon transistors but to build certain devices, such as ultradense memories,… read more

Hot Off the Presses, New Skin for Burn Victims

February 22, 2011

Using skin cells as ink and a human body as paper, James Yoo of Wake Forest University School of Medicine in Winston-Salem, North Carolina has designed a printer that can analyze a burn. First, it uses a laser scanner to determine the exact size and shape of the lesion. Then it creates a 3D reconstruction. Finally, it prints the layers of different cells needed — all in less than an… read more

(IMEC)

Researchers at the Interuniversity Micro-Electronic Centre (IMEC) in the Netherlands have developed a flexible, wireless cardiac patch that could help preempt serious illness by detecting early symptoms of heart trouble through continuous monitoring.

The new device just sticks onto the patient’s chest and wirelessly sends electrical signals detected from the heart to a credit-card-like receiver.

And other new software can even provide answers to unasked questions.

Radio for the YouTube Era?

March 1, 2011

Broadcastr, a Brooklyn-based start-up whose service went live on a public beta site on Monday, collects audio clips from various sources and pins them to physical locations, so people can be fed stories, audio tour guides and historical clips that are relevant to their physical locations.

Playlists can also be formed based on subject matter or source. The start-up’s founders see the project as a tool for… read more

TRANSCEND: Nine Steps to Living Well Forever by Ray Kurzweil and Terry Grossman, MD, published April 28, presents an easy-to-follow, practical, nine-step program to dramatically slow down aging and disease processes “so that you can be in good health when we get dramatic new technologies that will enable us to essentially reprogram the outdated ‘software’ (our genes) that runs in our bodies,” said Kurzweil. “These new methods are only ten… read more

More ‘functional’ DNA in genome than previously thought

December 12, 2007

Johns Hopkins researchers have found that the computer programs used in current methods of scanning the genome for regulatory DNA, regions of DNA that can control gene activity, could miss more than 60% of these regulatory DNA sequences.

In their pilot project, Hopkins researchers conducted an exhaustive analysis of the DNA sequence around the phox2b gene in Zebrafish, and found 17 regulatory sequences. The team then analyzed the entire… read more
