Red Sea Urchin Almost Immortal

December 17, 2003

The red sea urchin can last for more than 200 years with few signs of age-related disease, researchers have found. This could help scientists uncover the secret of longevity and aging.

Connected sky: surfing the web above the clouds

May 14, 2012


A recent deal between the British satellite telecommunications company Inmarsat and one of the biggest global aviation suppliers, Honeywell, may help give in-flight connectivity speed a boost.

Inmarsat plans to launch three satellites into orbit in the years to come, with the first one planned for 2013. The firm says the project, called Global Xpress, will provide global coverage and essentially make in-flight Wi-fi fast, cheap, reliable, and available… read more

Two supercomputers now exceed petaflop/s barrier

November 18, 2008

IBM’s Roadrunner, a 1.105 petaflop/s supercomputer at Los Alamos National Laboratory, retained the top spot as the world’s fastest supercomputer in the 32nd edition of the list of the world’s TOP500 supercomputers, released Friday.

A close second place went to the Cray XT5 supercomputer at Oak Ridge National Laboratory, called Jaguar. The system, only the second to break the petaflop/s barrier, posted a top performance of 1.059… read more

Researcher builds machines that daydream

September 27, 2010


Perth, Australia computer scientist Graham Mann is developing algorithms to simulate “free thinking” and emotion.

“I’ve reached the conclusion that an intelligent system must have emotions built into it before it can function….I believe that it is possible — if we start to model the way human beings reason about things — to achieve much more flexible processing of storylines, plans, even understanding how human beings behave,” he said.… read more

Peak Oil Theory faulty: CERA report

In contrast to a widely discussed theory that world oil production will soon reach a peak and go into sharp decline, a new report by Cambridge Energy Research Associates (CERA) finds that the remaining global oil resource base is actually 3.74 trillion barrels — three times as large as the 1.2 trillion barrels estimated by the theory’s proponents — and that the “peak oil” argument is based on… read more

Nanotube antennas boost signal reception

December 31, 2003

Antennas in the form of carbon nanotube transistors can dramatically enhance the reception of RF signals, according to a study by USC scientist Bart Kosko, a professor in the school’s Electrical Engineering Department.

The finding is based on a theory called “stochastic resonance” that claims noise, or unwanted signals, can actually improve the detection of faint electrical signals. Kosko’s graduate student, Ian Lee, generated a sequence of faint electrical… read more

Real-time Beethoven

November 24, 2008
(Line Halsnes)

Oyvind Brandtsegg, from the Norwegian University of Science and Technology, has created a new link between composition and improvisation.

His ImproSculpt software splits any live or recorded sound into a number of very short (1 to 10 millisecond)sound segments that can be infinitely reshuffled, making it possible to vary the music with no change in the fundamental theme, all controlled by a body sensor.

Breaking the noise barrier: Enter the phonon computer

October 5, 2010

A growing number of researchers and chip-makers are exploring ways to overcome electrical noise, which limits to performance of low-power chips.

In fact, it may one day be possible to use noise itself to store, carry and process information, opening up a new era of ultra-low-power computing.

The Future of War

November 29, 2006

Technology will increasingly allow the most sophisticated and best equipped militaries — primarily that of the US — to fight battles using robots rather than soldiers.

Ideas on the drawing board or in development include killer satellites that could destroy an enemy’s satellites, a Common Aero Vehicle (CAV) that could swoop with hypersonic speed up to 3,000 miles to attack a target, Hyper-Velocity Rod Bundles that would fire tungsten… read more

Ultimate Parasites Threaten Man

January 13, 2004

Viruses and bacteria are the ultimate parasites — and our only true predators. With the advent of international jet travel, these parasites can escape from their remote lairs to every corner of the world in just a few hours. The greatest threat humanity is facing is that one day a virus will emerge that can spread as efficiently as tuberculosis and that is as deadly as Ebola.

Making an Old Brain Young

December 1, 2008

New ways to manipulate neural plasticity–the brain’s ability to rewire itself–could make adult brains as facile as young ones, at least in part.

Drugs that target these mechanisms might eventually help treat neurological disorders as diverse as Alzheimer’s, stroke, schizophrenia, and autism.

Bio-ink printer makes stem cells differentiate

December 11, 2006

An inkjet device that prints tiny “bio-ink” patterns has been used to simultaneously grow both muscle and bone tissue from the stem cells of adult mice.

Surgeons could one day use the technology to repair various damaged tissues at the same time.

Microsoft, BBC test interactive 3-D photographic views of historic sites

June 7, 2007

Using its Photosynth technology, Microsoft Live Labs announced Wednesday a collaboration with the British Broadcasting Corp. in a time-limited technical trial to launch unique three-dimensional photographic representations of historic sites throughout the United Kingdom.

The online 3-D viewing experience will be available in conjunction with the BBC’s new series “How We Built Britain” beginning now and running through mid-July.

E-Mail Worm Snarls Computers Around Globe

January 28, 2004

A new malicious computer program (Mydoom or Norvag) is spreading rapidly throughout the Internet today, swamping e-mail in-boxes and crashing corporate computer servers in what some computer security analysts are predicting will become the largest ever outbreak of viral e-mail. It may eventually involve millions of machines, according to experts.

New record for information storage and retrieval lifetime advances quantum networks

December 8, 2008

Georgia Institute of Technology physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms: 7 milliseconds.

Even that short lifetime should be enough to allow transmission of data from one quantum repeater to another on an optical network.
