Possible Source of Cosmic Rays Found

November 4, 2004

Astronomers have discovered that a supernova is acting like a giant particle accelerator in space, and is thus a likely source of the cosmic rays in our galaxy.

Green groups baulk at joining nanotechnology talks

November 4, 2004

Leading environmental groups turned down invitations to join the International Council on Nanotechnology (ICON), set up to drive open discussion about the benefits and pitfalls of the nanotechnology.

California says ‘yes’ to stem-cell research

November 4, 2004

Californians said “yes” to Proposition 71, the California Stem Cell Research and Cures Initiative, which will raise $3 billion.

The measure will create the Institute for Regenerative Medicine, to distribute the funds and establish research guidelines. It will amend the state constitution to guarantee biologists’ right to do embryonic stem-cell research, and protect the institute from interference or supervision by the legislature.

Defining a Moment in History

November 3, 2004

National Public Radio’s Talk of the Nation has aired “Defining a Moment in History,” taking a step away from the election to talk about some of the key developments in other areas.

Ray Kurzweil was the guest representing “science” in this show, which is archived for listening.

Early embryos fuel hopes for shortcut to stem-cell creation

November 3, 2004

In an advance that could boost the production of stem cells for medical research, fertility researchers have grown human embryonic stem cells from an embryo that was younger (four days) than any used before.

First insects are cloned

November 2, 2004

Scientists have succeeded in cloning flies. The research may help to fine-tune the cloning process in other animals and even in humans, for therapeutic stem cells.

Mice Brains Can Fix Themselves

November 2, 2004

Harvard scientists have manipulated stem cells already present in the brains of mice to induce the birth of new neurons, an advance once considered impossible by most scientists.

They induced the birth of new cells by killing nearby neurons in mice, which set off a cascade of events that led to stem cells, producing new neurons in the cerebral cortex. If scientists can turn this into a therapy for… read more

The Futurist

November 1, 2004

Taking proper care of the body today, Ray Kurzweil believes, is a necessary step on the path to immortality for himself and his fellow baby boomers.

In 20 years, he predicts, biotechnology will be able to block the circuits that cause disease and will radically slow aging.

After that, what he calls the “full blossoming of nanotechnology” will allow us to replace the fragile and disease-prone cells we… read more

Nanotechnology Poised to Revolutionize Tech, Manufacturing Markets

November 1, 2004

Sales of products incorporating nanotechnology will total $2.6 trillion in 10 years, approximately one-sixth of the current Gross Domestic Product, greatly exceeding previous estimates, according to a new report released by Lux Research Inc.

The report predicts improvements across a wide range of industry categories including healthcare, water purification, materials, and information technology.

Nano Self-Assembly: An NSTI Executive Briefing

November 1, 2004

Another maturing vein of nano-science, “nano-structured fluids,” is capturing the imagination of some of the nation’s top nano researchers.

The Nano Science and Technology Institute (NSTI) will for the first time, provide an international briefing on why “nano-structured fluids” research is poised to dramatically change the direction of traditional nano-materials work, in a variety of unexpected ways.

Doctors Use Nanotechnology to Improve Health Care

November 1, 2004

Evidence is accumulating that nanotechnology may enable better early warning systems for cancer and heart disease, cures for progressive diseases like cystic fibrosis, techniques for making implants like artificial hips more successful, and even artificial kidneys.

Now, for example, device makers not only shape the surfaces of their products, but they may also add specialty coatings like those from Biophan Technologies. Biophan’s coatings, made up of magnetic particles 20… read more

Organised chaos gets robots going

November 1, 2004

A control system based on chaos has made a simulated, multi-legged robot walk successfully.

In chaotic systems, small effects are amplified so rapidly that the systems’ behavior becomes impossible to predict more than a short time ahead.

The robot was able to learn to walk and negotiate obstacles without any conventional programming. And its behavior emerged far more quickly than it would if it had used genetic algorithms.… read more

Natalie Jeremijenko: The WorldChanging Interview

November 1, 2004

From releasing packs of Feral Robot Dogs that sniff out chemical contamination, to teaching Yale engineering students socially responsible design, from creating pollution-detecting Clear Skies Masks for bicycle riders, to co-authoring Biotech Hobbyist Magazine, Natalie Jeremijenko’s work merges engineering, biology and art to explore socio-political hot spots along the fault line where design meets information meets society.

Pompeii gets digital make-over

November 1, 2004

The Lifeplus project will provide tourists with computer-augmented versions of archaeological attractions.

Visitor will wear a head-mounted display with a miniature camera and a backpack computer. The camera captures the view and feeds it to software on the computer, where the visitor’s viewpoint is combined with animated virtual elements.

At Pompeii for example, the visitor would not just see the frescos, taverns and villas that have been excavated,… read more

Research to explore gene sequencing

October 29, 2004

The National Human Genome Research Institute (NHGRI) of the National Institutes of Health has awarded a $550,000 three-year grant to Stuart Lindsay of Arizona State University to further develop a nanotechnology project for rapid genetic profiling.

The new sequencing technology involves using Atomic Force Microscopy (AFM) in combination with naturally occurring ring-shaped sugar molecules called cyclodextrins. Lindsay believes that the ring molecules, when paired with the AFM probe tip,… read more
