Bionic ‘sex chip’ that stimulates pleasure centre in brain developed by scientists

December 22, 2008

Scientists are developing an electronic “sex chip” that works by stimulating the orbitofrontal cortex, which is associated with the pleasure felt when eating and having sex.

A Web That Thinks Like You

July 5, 2007

Radar Networks plans later this year to launch Radar, which uses semantic Web technologies to help individuals and communities mine and share information from Internet sites, blogs, and social media services.

Built-in artificial intelligence will continually learn as people use the service and computers troll for similar information.

Water Filters Rely on Nanotech

October 15, 2004

A slow, methodical transformation of the $400-billion-a-year water-management industry is currently in progress, and nanotechnology appears to be leading the way.

The promise of nanofiltration devices that “clean” polluted water, sifting out bacteria, viruses, heavy metals and organic material, is driving companies like Argonide and KX Industries, which developed technology used in Brita filters, to make nanotechnology-based filters for consumers. Two products incorporating nanotechnology are going to hit the… read more

Exercise and your brain: Why working out may help memory

December 31, 2008

Researchers from four universities report in the Annals of Neurology that people who absorb glucose more slowly than those who metabolize it quickly are more forgetful and are more likely to have a faulty dentate gyrus, a pocket in the hippocampus section of the brain. The hippocampus is involved with learning and memory formation.

Researchers noted in previous studies that physical activity reduced the risk of age-related memory loss… read more

Quest for Synthetic Organisms Calls for New Rules, Critics Say

July 12, 2007

Critics say questions about dangers that could arise with manmade organisms — which can reproduce on their own — remain unaddressed.

“The notion is that, as we engineer more complex systems, our ability to predict their behavior diminishes,” said Boston University microbiologist James Collins. “How can we ensure that we don’t create something dangerous? Now is the time to start thinking about it.”

Until manmade organisms are fully… read more

TI Puts Digital TV on Cell Phones

October 22, 2004

Texas Instruments Inc. today announced development of the wireless industry’s first digital TV on a single chip for cell phones.

The chip will receive live digital TV broadcasts at 24 to 30 frames per second. Manufacturers are expected to launch products in conjunction with a new mobile digital TV infrastructure, with mass deployments in 2007.

New Tech Makes Classroom Computers a Reality Worldwide

January 9, 2009

Intel on Friday at the Consumer Electronics Show will unveil its new low-priced simplified PCs Classmate netbook PC, which is faster than its predecessors, with a touch screen for easier use, intended for kids worldwide, especially in developing countries, and costs about $300 to make.

Bio-printing tissues for cheaper, faster drug testing

3D-printing technology specifically tailored to printing biological materials, not repurposed
March 28, 2014


Bio-printed tissues can help better predict and test whether a drug will be effective on people and at less cost, researchers at the University of British Columbia Department of Electrical and Computer Engineering and spinoff Aspect Biosystems hope to prove.

Ultimately, this work could also lead to growing organs for human transplant.

Developing a new drug costs upward of $4 billion, a fee that gets passed… read more

Saving Neurons and Memories

July 24, 2007

Harvard and MIT scientists have shown that the SIRT1 gene and resveratrol can protect against neuron degeneration of Alzheimer’s disease and amyotrophic lateral sclerosis in a mouse model.

The Harvard/MIT study could also shed light on the mechanisms behind Alzheimer’s.

Presidential panel urges more flexible use of spectrum

June 1, 2012

radio spectrum

A just-completed report from a presidential advisory committee urges President Obama to issue an executive order to adopt new “cognitive” or “agile” radio technologies to make better use of a huge swath of the radio spectrum now controlled by federal agencies.

The plan calls for electronically sharing spectrum for short periods of time using newly available computerized radio technologies,

Doctors Use Nanotechnology to Improve Health Care

November 1, 2004

Evidence is accumulating that nanotechnology may enable better early warning systems for cancer and heart disease, cures for progressive diseases like cystic fibrosis, techniques for making implants like artificial hips more successful, and even artificial kidneys.

Now, for example, device makers not only shape the surfaces of their products, but they may also add specialty coatings like those from Biophan Technologies. Biophan’s coatings, made up of magnetic particles 20… read more

Human Markup Language

March 27, 2001

A Human Markup Language discussion group has been formed to help define XML standards for gestures, thoughts, emotions, and attitudes. There’s an initial proposal.

Our world may be a giant hologram

January 16, 2009

Fermilab scientists have found anomalous “holographic noise” in their GEO600 gravitational-wave detector that suggests the possibility that we live in a hologram.

Virtual worlds: Perfect for studying humans?

August 1, 2007

William Sims Bainbridge — co-director of Human-Centered Computing at the National Science Foundation (NSF) — wrote in a review paper published in last week’s Science that virtual worlds would be ideal for performing sociological experiments.

Cited benefits include tapping into an unusually large population of subjects, acquiring lots of quantitative data about everyday activities, and repeating experiments under near identical circumstances.

A few pioneering researchers, such as Mary… read more

Could future computer viruses infect humans?

November 15, 2004

Kevin Warwick, professor of cybernetics at Reading University, warned the day will come when computer viruses can infect humans as well as PCs.

“We’re looking at software viruses and biological viruses becoming one and the same,” he said. “The security problems [will] be much, much greater… they will have to become critical in future.”

If humans were networked, the implications of being hacked would be far more serious… read more
