Independent robots team up for search task

June 14, 2006

Researchers at the University of Pennsylvania have created a team of autonomous flying and ground-based robots that have successfully cooperated to search for and locate targets in the streets of an urban warfare training ground.

Semantic Sense for the Desktop

December 17, 2008

A European endeavor called the Nepomuk Project plans to introduce the Semantic Web to computers in the form of a “semantic desktop.”

The software generates semantic information by using “crawlers” to go through a computer and annotate as many files as possible. These crawlers look through a user’s address book, for example, and search for files related to the people found in there. Nepomuk can then connect a file… read more

Fastest network simulations

August 11, 2003

Researchers at the Georgia Institute of Technology have created the fastest detailed computer simulations of computer networks ever constructed, simulating networks containing more than 5 million network elements and more than one million web browsers in near real time.

This work will lead to improved speed, reliability and security of future networks such as the Internet, according to Professor Richard Fujimoto, lead principal investigator of the DARPA-funded project.… read more

Brain Boosters

June 28, 2007

A Technology Review reporter enters the new world of neuroenhancers by having his brain zapped with electricity and dosed with chemicals.

Immortality Institute’s Second Book Project invites abstracts

June 26, 2006

The Immortality Institute is inviting abstracts for possible chapters in a forthcoming anthology on the science and ethics of life extension.

ImmInst’s first book, “The Scientific Conquest of Death,” is available online and includes eighteen essays from leading scientists such as Aubrey de Gray, Ray Kurzweil, Marvin Minsky, Robert Freitas, Nick Bostrom, Max More, Mike West and William Sims Bainbridge.

World record data density for ferroelectric recording

August 18, 2010

Scientists at Tohoku University in Japan have recorded data at a density of 4 trillion bits per square inch,  a world record for the experimental ferroelectric data storage method, and about eight times the density of today’s most advanced magnetic hard-disk drives.

The data-recording device uses a tiny cantilever tip that rides in contact with the surface of a ferroelectric material. To write data, an electric pulse is sent… read more

A year in the quantum world

December 26, 2008

Four radical routes to a theory of everything, The great antimatter mystery, Anyons: the breakthrough quantum computing needs?, and Matter is merely vacuum fluctuations are among the year’s top 10 in-depth articles about the quantum world.

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.

Forcing cancer cells to shape-shift stops them from migrating, Mayo Clinic researchers find

December 12, 2013

Shape-Shifting

Researchers at Mayo Clinic in Florida have identified a number of agents — some already used in the clinic for different disorders — that may force shape-shifting in tumor cells to immobilize them and thus prevent metastasis.

“We are starting to understand mechanistically how cancer cells move and migrate, which gives us opportunities to manipulate these cells, alter their shape, and stop their spread,” says the study’s lead… read more

Scientists Create Breakthrough Sensor Capable of Detecting Individual Molecules

July 9, 2007

Applied physicists at the California Institute of Technology have figured out a way to detect single biological molecules with a microscopic optical device.

The method has already proven effective for detecting the signaling proteins called cytokines that indicate the function of the immune system, and it could be used in numerous medical applications, such as the extremely early detection of cancer and other diseases, as well as in basic… read more

Make way for the terabyte laptop drive

July 7, 2006

Seagate Technology Inc. plans to increase disk capacity by 10 times with new technology it has just patented, meaning a computer hard drive could soon be storing as much as a terabyte of data.

The Heat-Assisted Magnetic Recording (HAMR) technology created by Seagate includes nanotube-based lubrication to allow the read/write head of a disk to get closer to the surface and store more information.

Hand-held detector aims to diagnose disease

August 27, 2010

(Cambridge Consultants)

Cambridge Consultants is developing CliniHub, a cheap detector that senses a telltale fluorescent glow from disease markers.

Credit-card-sized sample trays inserted in a modem-sized reader hold antibody-coated polystyrene beads containing a fluorescent label. The antibodies interact with specific disease markers, causing the beads to clump together, quickly producing a strong red fluorescence under UV light from an LED. That glow is picked up by a built-in light detector based on… read more

Sharpest infrared image of Milky Way’s core unveile

January 6, 2009

Astronomers released the sharpest infrared picture yet taken of the center of our galaxy, revealing massive filaments of gas and a new population of about 200 massive, rogue stars.

Is it time to move beyond zeroes and ones?

August 27, 2003

The economics of semiconductor manufacturing now is forcing us to consider moving beyond binary to ternary and quaternary logic.

This would effectively increase a device’s information density without further shrinking the transistor structure. This option should be considered as we move ultimately into the sub-nanometer range, where we are already facing problems relating to the cost of the fabrication equipment and more fundamentally, quantum uncertainties.

TransVision 2007 explores transhuman frontiers

July 17, 2007

Would you store the essence of your self in digital mindfiles that can be revived in the future via cyberconsciousness mindware so future scientists could bring “you” back via cybernetic consciousness or cellular/nanobio regeneration? Do we live in an “almost spookily bio-friendly” intelligent universe where we will some day create baby universes? When neurological enhancements can create believable simulated worlds like Second Life in your own brain, where and who… read more
