Molecular Manufacturing: Start Planning

August 20, 2003

“There is very little doubt that molecular nanotechnology manufacturing will be developed within the next three decades,” says Chris Phoenix, Director of Research for the Center for Responsible Nanotechnology, and it may be as soon as ten years because of the immense utility and the increasing ease of development.

But there are risks: an unstable arms race, criminal and terrorist activity, invasion of privacy from microscopic devices, gray goo,… read more

Down on the pharm

August 20, 2003

Genetically modified crops that produce drugs are the latest rage. But American farmers are lighting a prairie fire of revolt.

Free online journal gives sneak preview

August 20, 2003

The Public Library of Science has released a sneak preview of the research papers it will be giving away for free from October. Its first journal, PLoS Biology, is a monthly, peer-reviewed journal intended to compete head-to-head with the most prestigious paid-for journals.

Big questions for tiny particles

August 19, 2003

From clear sunscreen to self-cleaning cars, nanotechnology seeps into daily life and starts to raise tough ethical issues.

Computer model forecasts crime sprees

August 19, 2003

A more powerful tool for forecasting crime is emerging from a huge electronic database of six million crimes.

A team from Carnegie Mellon University analyzed the data in two ways: A statistical analysis that spots broad trends allowed researchers to quantify the rules of thumb that police officers often learn from experience; and a list leading indicators — minor offences such as vandalism and trespassing that crime analysts believe… read more

Aggregators Attack Info Overload

August 19, 2003

A new breed of software, called newsreaders or aggregators, is helping manage information overload by allowing users to subscribe to feeds from diverse news sources and blogs.

Gamma-ray weapons could trigger next arms race

August 19, 2003

An exotic kind of nuclear explosive being developed by the US Department of Defense could blur the critical distinction between conventional and nuclear weapons. The work has also raised fears that weapons based on this technology could trigger the next arms race.

One gram of fully charged hafnium isomer could store more energy than 50 kilograms of TNT. Miniature missiles could be made with warheads that are far more… read more

Company Plans Power ‘Valve’ Employing Superconductors

August 18, 2003

To suppress surges, Intermagnetics General plans to use superconductors as valves on the electric-utility power grid, letting their temperature rise to choke off the flow of power. The device would also generate a magnetic field, which further lowers superconductor conductivity.

The idea is to reduce the surge to a level that conventional circuit breakers can handle.

Human-rabbit embryos intensify stem cell debate

August 18, 2003

“Human” embryonic stem cells have been harvested from cloned embryos created by fusing human cells with rabbit eggs, claims a soon-to-be published report by Chinese scientists.

The goal of the experiments: create a new source of embryonic stem cells (ESCs), which can transform into any tissue, making them potential sources of replacement cells for the treatment of many diseases.

Unlike controversial fertilized human embryos, which must be destroyed… read more

Power Up!

August 18, 2003

The electricity grids of all the nations of North and South America should be interconnected within the next 10 years. Twenty years from now, the whole world will be sharing electricity through one grid.

By making electric power as easily transferrable as data, analysts expect a global grid to smooth the market spikes out of the world’s most useful commodity.

For Those Needing 32 More Bits

August 18, 2003

The arrival of 64-bit desktop processors signifies a new era of computing — initially for professionals who are bumping up against the memory limits of existing PC’s. Soon afterward the new chips will affect everyday computer users, for whom a new generation of media machines should offer remarkable improvements in audio and visual effects.

DNA Power Computing? Could Be

August 18, 2003

A growing amount of research supports the idea that DNA, the basic building block of life, could also be the basis of a staggeringly powerful new generation of computers.

Columbia University researcher Milan Strojanovic and a colleague published a paper in the current issue of the journal Nature Biotechnology describing how they built a biological-based computer that can’t lose a game of tic-tac-toe to man and doesn’t need any… read more

It’s a Flawed World After All

August 18, 2003

The recent MSBlaster worm and power blackout incidents have laid bare the brittleness of increasingly complex, interconnected systems, leading some to question their near-total dependence on them.

Smart chips making daily life easier

August 18, 2003

The Smart-Its Project has a vision to tag almost any object in the home with microchips to make peoples’ daily lives easier.

For examples, the sensors would recognize if has fallen on the floor or can’t stand up, which is less intrusive than cameras.

Are Pulsar Signals Evidence of Astro-Engineered Signalling Systems?

August 18, 2003

In his recent book, The Talk of the Galaxy, Dr. Paul LaViolette shows how new high-resolution recordings of pulsar signals reveal features that are inconsistent with the long-standing “neutron star lighthouse” pulsar model.

LaViolette argues compellingly that the interesting and quite intricate behaviors of pulsars fit much more easily with a model of an extraterrestrial intelligence (ETI) beacon carrying information.

For example, pulse transmissions may be interrupted for… read more
