Freedom Phones and PINs: How to Find Osama bin Laden and Other Terrorists

October 1, 2001

Scientists and Middle East experts have come up with an idea for inexpensive “informer cell phones” dropped from airplanes and an anonymous reward scheme to encourage those with information on the identity and whereabouts of terrorists to provide this information to U.S authorities such as the FBI. The intelligence gathering operation, proposed by physicist and radio personality Dr. Bill Wattenberg on KGO radio in San Francisco, uses a unique PIN… read more

Unveiling the “Sixth Sense,” game-changing wearable tech

March 11, 2009

TED has just released the video of MIT scientists Pattie Maes & Pranav Mistry unveiling their “Sixth Sense,” a wearable device with a projector, as in Minority Report — the buzz of TED.

Invisibility Made Easier

October 15, 2007
Anthony Hoffman, Princeton University

Princeton University researchers have demonstrated a new way to create metamaterials that bend light in unusual ways.

The new proces allows for metamaterials that are both higher performing and much easier to manufacture, perhaps bringing these applications closer to reality.

Tiny Is Beautiful: Translating ‘Nano’ Into Practical

February 22, 2005

Nanoparticles of various sorts are already found in products like sunscreen, paint and inkjet paper. More exotic varieties offer promise in medicine for sensitive diagnostic tests and novel treatments: the detection of Alzheimer’s disease by finding a protein in spinal fluid, for instance, or nanoparticles that heat up and kill cancer cells.

Blood vessels for lab-grown tissues

January 12, 2011

Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They’ve found a way to grow the blood vessels and capillaries needed to keep tissues alive.

The new research is available online and due to appear in the January issue of the journal Acta Biomaterialia.

“The inability to grow blood-vessel networks –… read more

Devastating attacks on the net ‘imminent,’ says report

October 26, 2001

A new wave of devastating Internet attacks is just waiting to happen and there is there is currently little chance of preventing it.
The threat is a variation of the “denial of service” (DoS) attack, commonly used by malicious hackers to block a website by bombarding it with spurious requests. However, the new threat would target routers, key hubs of the Internet’s infrastructure, instead of individual websites.

“We believe… read more

Robot Plays Follows the Leader

March 17, 2009

Image-recognition software and an infrared camera developed at Brown University let a robot follow people in different environments.

India to host world toilet summit

October 25, 2007

Health and sanitation experts from 40 countries will meet in New Delhi later this month to find ways to provide toilets for everyone by 2025.

An estimated 2.6 billion people have no access to a proper toilet, according to the World Health Organization. More than half live in India or China.

Scientists to make ‘Stuart Little’ mouse with the brain of a human

March 9, 2005

Stanford University researchers plan to create a chimera mouse whose brain cells are 100 per cent human, using stem cells from aborted fetuses.

The university’s ethics committee approved the research, under certain conditions. Prof Henry Greely, the head of the committee, said: “If the mouse shows human-like behaviours, like improved memory or problem-solving, it’s time to stop.”

3D Technology: Ready for the PC?

November 27, 2001

Technology advances such as accelerated graphics cards and graphics ports have driven PC hardware capabilities up and prices down, making 3D more accessible to consumers and furthering research on methods and algorithms.

Another key trends is overcoming network-bandwidth limitations by sending compressed content instead of full-resolution geometry.

3D graphics can be used to visualize objects and products prior to construction, model weather systems for meteorologists, study medical anomalies… read more

Brain wave patterns can predict blunders, new study finds

March 24, 2009
(Donders Institute)

A distinct electric signature in the brain that predicts that an error is about to be made has been found by UC Davis and Donders Institute neuroscientists by analyzing recorded magnetoencephalographic (MEG) brain activity.

About a second before errors were committed, alpha wave activity was about 25 percent stronger in the back of the head (the occipital region), and in the middle region, the sensorimotor cortex, there… read more

The Charge of the Ultra-Capacitors

November 5, 2007

MIT scientists plan to replace the activated carbon of current ultracapacitors, which can can store more charge than a capacitor, with a dense, microscopic forest of carbon nanotubes grown directly on the surface of the current collector.

This would create a device that can hold up to 50 percent as much electrical energy as a comparably sized battery, while being more effective at rapid, regenerative energy storage than chemical… read more

Microbes used to make bioelectronic circuits

March 18, 2005

University of Wisconsin-Madison scientists have used single bacterial cells to make tiny bioelectronic circuits.

The bacteria, are guided, one at a time, down a channel to a pair of electrodes and become electrical “junctions,” allowing researchers to capture, interrogate and release bacterial cells one by one. Built into a sensor, such a capability would enable real-time detection of dangerous biological agents.

Reverse-Engineering the Visual Process

December 19, 2001

Researchers at the Office of Naval Research are using a combination of engineering and neurobiology to model mammalian brain processes.They are learning how the architecture and physiological properties of cells in visual cortex integrate visual cues for target recognition.

“Right now we’re building a cellular-level model of a small piece of visual cortex,” says Dr. Leif Finkel, head of the University of Pennsylvania’s Neuroengineering Research Lab. “It’s a very… read more
