Atom laser-beam microscope

July 17, 2001

An atom laser-beam microscope that could have sharper vision while causing less damage to a sample than an electron microscope is being developed by physicists at the Ludwig-Maximilians University in Munich.

The development of lenses and mirrors to sharpen atom laser beams might also improve technologies to build atomic-scale structures, similar to how an ink-jet printer writes text.
Just as an optical laser beam is better than a light… read more

The emerging science of DNA cryptography

March 19, 2009

A new approach to using DNA for data encryption, based on how information from DNA is processed inside cells, has been developed by independent researcher Nang King.

Micromachine grows its own muscles

January 18, 2005

UCLA scientists ahve developed a micromachine that walks using muscles that it grows for itself. The device could lead to nanobots that clear away plaque from inside the walls of a human coronary artery or to muscle-based nerve stimulators that let paralyzed patients breathe without a ventilator.

They built the micromachine by etching the silicon structure using photolithography before coating the frame with a polymer and selectively depositing gold… read more

Technology, the Stealthy Tattletale

October 29, 2007

A technological revolution is making it possible to track down escaping bank robbers and find missing things and people far more quickly and precisely than ever.

The change is powered less by new technologies than the artful combination of existing ones, mainly the Internet, cellphones and GPS satellites. In some cases, the new devices linked to these systems can even detect a theft before it happens.

SGI Reality Center wows SIGGRAPH attendees

August 15, 2001

LOS ANGELES, August 14 — SGI is wowing SIGGRAPH attendees with its 35 by 10 foot wraparound immersive Reality Center visualization facility here.The display seamlessly combines images from three projectors driven by SGI Onyx 3400 computers, generating 3.5 million pixel images in real time.

Demonstrations include a breathtaking journey through the sixth-century Buddhist kingdom of Silla, from the SGI Reality Center in Seoul, Korea; an urban drive-around simulation of… read more

The World’s Biggest Laser Powers Up

March 26, 2009

The National Ignition Facility (NIF), a laser system designed to produce nuclear fusion reactions that release more energy than used to produce them, is now up and running.

By 2010 or 2011 the NIF’s 192 lasers will be able to deliver 1.8 megajoules of energy in a few billionths of a second to one 2-millimeter sphere filled with hydrogen isotopes. The energy will ignite a fusion reaction and generate… read more

Animal-Human Hybrids Spark Controversy

January 27, 2005

Scientists have begun blurring the line between human and animal by producing chimeras—a hybrid creature that’s part human, part animal.

Chinese scientists at the Shanghai Second Medical University in 2003 successfully fused human cells with rabbit eggs.

In Minnesota last year researchers at the Mayo Clinic created pigs with human blood flowing through their bodies.

And at Stanford University in California an experiment might be done later… read more

Mirror, Mirror In The Brain: Mirror Neurons, Self-understanding And Autism Research

November 8, 2007

Recent findings are rapidly expanding researchers’ understanding of mirror neurons, which are active both when people perform an action and when they watch it being performed.

Accelerated Living

September 7, 2001

“Imagine a Web, circa 2030, that will offer a panoply of virtual environments incorporating all of our senses, and in which there will be no clear distinction between real and simulated people.” That’s part of Ray Kurzweil’s imaginative view of the future in PC Magazine’s special “20th Anniversary of PCs” issue.
Among Kurzweil’s other forecasts for the next 30 years:

  • Miniaturized displays on our eyeglasses will provide
  • read more

    Real-Time Searches Lead to Real-Time Malware

    July 30, 2010

    Searching for a hot news topic or buzzword can lead an unsuspecting person to harmful malware, said Dan Hubbard, CTO of Websense, at the Cloud Security Alliance Summit, which took place at the Black Hat security conference in Las Vegas.

    Estimates have suggested that about 14 percent of traditional searches for trending news go to sites hosting malware.

    Much of the problem stems from the nature of information… read more

    DNA-Based Assembly Line for Nano-Construction of New Biosensors, Solar Cells (w/Video)

    March 31, 2009

    A molecular assembly line using DNA linkers for predictable, high-precision nano-construction has been developed by scientists at the U.S. Department of Energy’s Brookhaven National Laboratory.

    Quantum well’ transistor promises lean computing

    February 11, 2005

    Researchers at Intel and Qinetiq have developed a transistor that uses one-tenth of the power of existing components.

    It uses indium antimonide, which allows electrons to speed through faster than conventional silicon-based transistors due to its highly active and greater number of charge carriers.

    European researchers have demonstrated a new method for hydrogen production by algae.

    In a recent issue of PNAS, the team presented a method using copper to block oxygen generation in the cells of Chlamydomonas reinhardtii that could lead to a consistent cycle of hydrogen production.

    Tech Companies See Market for Detection

    October 1, 2001

    Cutting-edge identification and detection technologies have helped specialists in the battle against terrorism, but the Sept. 11 attacks on the Pentagon and the World Trade Center could transform these once exotic gadgets into everyday tools of airport safety.
    Biometrics technologies include detecting stress by reading flickering eye movements, X-rays to conduct virtual strip-searches, facial recognition (videotaping faces in a crowded room and matching them to known terrorists), measuring eye movements… read more

    Mind-reading marketers have ways of making you buy

    August 9, 2010

    The great hope of neuromarketing is to use EEG and fMRI machines to extract subconscious hidden information directly from people’s brains, bypassing unreliable verbal reports. Neuroeconomists now think of the amount of activity in the emotion-related limbic system as a sort of universal currency of desirability, allowing the brain to weigh up different rewards.
