Proteins produce nano-magnetic computer memory

April 28, 2003

Computer hard drive capacity could be increased a hundredfold by using the protein apoferritin (the main molecule in which iron is stored in the body) to fabricate nanoscale magnetic particles, claims UK company Nanomagnetics.

Each particle can store a bit of information; they can be packed onto a disk drive at much greater density than with existing hard disk manufacturing methods.

Unusually long and aligned ‘buckytubes’ grown at Duke

April 25, 2003

Duke University chemists have developed a method of growing nanotubes 100 times longer than usual (4 mm.), while maintaining straightness with controllable orientation and cross-connecting nanotube grids. The achievement solves a major barrier to nanotubes’ use in ultra-small nanoelectronic devices.

Engineers aim to make average singers sound like virtuoso

April 25, 2003

Researchers are creating computer models for voice analysis and synthesis that break the human singing voice into components (such as pitch, duration, and vibrato) that can then be modified to produce a more professional-sounding rendition of the original voice.

Microsoft to Use Radio Waves on Devices

April 25, 2003

Microsoft Corp. is using FM radio waves to deliver instant messages, headlines and traffic updates to a new generation of gadgets that will fit on your wrist or keychain.

Nanotech is ready for its closeup

April 25, 2003

Molecular movies are helping IBM understand how molecules can be directed to assemble into useful structures. Using a stream of electrons, the system can resolve structures as small as 5 nanometers.

The End of Human Nature

April 24, 2003

“We’re headed toward an era when human beings will be as casually “enhanced” as chickens or marigolds, with higher IQs, better looks, longer lives.”

In his book, Enough: Staying Human in an Engineered Age, Bill McKibben “indicts germline technology, the so-called designer baby science that aims to let parents improve their offspring by pasting desirable genes into their kid’s DNA.”

Unusually Long and Aligned ‘Buckytubes’ Grown at Duke

April 23, 2003

Duke University chemists have developed a method of growing one-atom-thick cylinders of carbon (nanotubes) 100 times longer than usual, while maintaining a soda-straw straightness with controllable orientation. Their achievement solves a major barrier to the nanotubes’ use in ultra-small nanoelectronic devices, said the team’s leader.

Baby teeth revealed as source of stem cells

April 23, 2003

Scientists have discovered that baby teeth are a source of stem cells. The cells could differentiate into neural cells and fat cells to help repair damaged teeth and perhaps even treat neural injuries or degenerative diseases.

Dealing with future nanotech dangers

April 22, 2003

New York — The Center for Responsible Nanotechnology (CRN) issued a report today identifying 11 significant risks of molecular nanotechnology (MNT) along with possible solutions.

MNT has “the potential to disrupt many aspects of society and politics,” the report says. “The power of the technology may cause two competing nations to enter a disruptive and unstable arms race. The flexibility and small size of molecular manufacturing systems and their… read more

Distributed computers power new search engine

April 22, 2003

A distributed computing project called Grub, which harnesses individual users’ spare computing power and Internet bandwidth, began cataloguing millions of web pages this week.

LookSmart, the US company behind Grub, believes the distributed service has the potential to one day rival Google.

Startups Seek Perfect Particles To Search And Destroy Cancer

April 21, 2003

Several companies are developing new cancer treatments that send nanoparticles into patients’ bodies to find tumor cells. Once they do, doctors excite the particles with electromagnetic energy to attack the tumor without collateral damage to nearby healthy cells and without the frightening side effects of chemotherapy and radiation: hair loss, nausea, and ravaged immune systems.

The Unmanned Army

April 21, 2003

“The unmanned combat aerial vehicle (UCAV) is the first tangible evidence of [a] robotic future….If the UCAV program succeeds, it could lead us to a distant point on the horizon where no Americans in uniform will ever again fight on the battlefield — automated submarines launching cruise missiles, divisions of unmanned ground vehicles racing toward enemy capitals. Autonomous helicopters will charge ahead of the columns, flying 15 feet off the… read more

Planning for the Next Net War

April 18, 2003

The Department of Defense is introducing network-centric warfare in Iraq, using “real-time video images to target missiles in flight, wireless PDAs to connect with stateside medical records from the battlefield, and virtual- reality simulations to provide just-in-time delivery of material to front-line troops.”

Future war technologies will include information from sensors reporting such things as the shape of radar waveforms, acoustic signals and seismic analysis, used to immediately notify… read more

In the Skies Over Iraq, Silent Observers Become Futuristic Weapons

April 18, 2003

“Remotely piloted aircraft like the Predator have played a crucial role in the Iraq war, not only providing a bird’s-eye view of the battlefield but also giving military planners the ability to kill fiercely defended targets with a futuristic weapon — all without risking American lives.”

All the armed services are now using unpiloted aerial vehicles, with more than ten different unmanned aerial vehicles on the battlefield.
