Live holographic tumor imaging demonstrated

May 10, 2002

Purdue University scientists are developing a new imaging technology that allows for the first “visual fly-throughs” of a living tumor.

The technique, called optical coherence imaging, uses lasers, holograms, and real-time “dynamic holographic films,” consisting of alternating layers of gallium arsenide and aluminum gallium arsenide semiconductors.

Ray Kurzweil reviews Stephen Wolfram’s long awaited new book ‘A New Kind of Science’

May 10, 2002

On May 14, Stephen Wolfram’s new book “A New Kind of Science,” which he has spent more than ten years writing, goes public. Wolfram, the creator of Mathematica software, presents what he describes as “dramatic discoveries” based on his experiments with cellular automata.
The book addresses a wide array of fundamental issues in science, from the origins of apparent randomness in physical systems to the development of complexity… read more

Supercomputing platform built for gaming

May 13, 2002

The “Butterfly Grid,” a distributed supercomputer games network, could allow more than a million people to play graphics-rich games together via the internet.
The project borrows scientific supercomputer “grid” techniques developed to seamlessly connect scientific computers for research, sharing power and storage via the Internet.

West Virginia-based Butterfly has developed the software that will allow game developers to enable any game to plug into the network… read more

DNA nanoballs boost gene therapy

May 14, 2002

Researchers have developed a way to pack a DNA molecule into 25 nanometer particles, small enough to enter the nuclear pores or cells and make gene therapy safer and more efficient. The technique is now being tested on people with cystic fibrosis.

“In cells grown in culture, there was a 6000-fold increase in the expression of a gene packaged this way compared with unpackaged DNA in liposomes.”

Scientists Get Atoms Ready for a Close-Up

May 15, 2002

Scientists at Lucent Technologies’ Bell Labs have developed a microscopy technique that can image individual atoms within a silicon sheet, allowing for precision analysis of dopant distribution.
As transistor sizes shrink, they require higher concentrations of electrons to work and are more sensitive to problems with dopant distribution.

The Lucent microscope shoots a narrow beam of high-energy electrons and measures deflection angles to locate individual atoms.

Nano breakthrough charges science world

May 21, 2002

IBM researchers have created carbon nanotube field-effect transistors (CNFETs) that suggest that CNFETs may be competitive with Silicon MOSFETs for future nanoelectronic applications.
CNFETs deliver more than twice the amount of electrical current at a faster rate than silicon transistors. Increased current can lead to faster transistors and integrated circuits, so carbon may become a building block of computing in the future.
