Nanoscale ‘Coaxial Cables’ for Solar Energy Harvesting

April 25, 2007
A cross-section of the nanoscale coaxial cable, in which nitrogen, phosphorus, and gallium atoms are shown in blue, yellow, and magenta, respectively. White spheres represent hydrogen atoms, which help render the surface of the wire chemically non-reactive.

Scientists have designed a new type of nanowire — a tiny coaxial cable – that could vastly improve a few key renewable energy technologies, particularly solar cells, and could even impact other cutting-edge, developing technologies, such as quantum computing and nanoelectronics.

NPR’s ‘OnPoint’ interviews Ray Kurzweil on Radical Life Extension

July 9, 2004

Futurist Ray Kurzweil was interviewed by NPR “On Point” host Tom Ashbrook on radical life extension, Monday, July 12th, 8-9 p.m. EST.

On “Living Forever,” Kurzweil discussed how to dramatically slow down the aging process, even stop and reverse it, and the social and cultural ramifications. He also described his forthcoming book, “Fantastic Voyage: Live Long Enough to Live Forever,” co-authored with Terry Grossman, M.D.

A System for Connecting Brains to the Outside World

August 3, 2010

Dr. John Donoghue, a professor of engineering and neuroscience at Brown University, speaks with the New York Times about his studies of how human brain signals could combine with modern electronics to help paralyzed people gain greater control over their environments. He’s designed a machine, the BrainGate, that uses thought to move limbs.

Obama Election Ushering In First Internet Presidency

November 7, 2008

The Obama administration is expected to build on a foundation of grassroots support in his private social network, on Facebook, YouTube, and Twitter, and a similar social networking for his legislative initiatives, recruiting supporters to lobby Congress to get his policies enacted into law.

Detecting objects as small as protein molecules using multispectral imaging

December 10, 2013

Die encapsulated in carbon nanotube improves detection by

Richard Martel and his research team at the Department of Chemistry of the University of Montreal have discovered a method to improve detection of the “infinitely small” by encapsulating a dye inside carbon nanotubes for multispectral imaging.

Raman scattering provides information on the ways molecules vibrate, which is equivalent to taking their fingerprint. It’s a bit like a bar code,” said Martel. “Raman signals are… read more

Doctors Change the Way They Think About Death

May 2, 2007

Standard emergency-room procedure has it backward, says Dr. Lance Becker, director of the University of Pennsylvania Center for Resuscitation Science: blood-starved heart muscle is suddenly flooded with oxygen, precisely the situation that leads to cell death.

Instead, Becker says, we should aim to reduce oxygen uptake, slow metabolism and adjust the blood chemistry for gradual and safe reperfusion.

Motorola rolls out Wi-Fi phone

July 27, 2004

Motorola has introduced a new phone that it says will switch calls seamlessly between cellular services and wireless WiFi Internet networks, potentially offering big savings for customers.

It is planned to be commercially available by fall or early 2005,

Removing a barrier to regrowing organs

August 11, 2010

Disabling an evolutionary backup plan for protecting against cancer could be part of a future means to regrow lost limbs or regenerate damaged organs.

A protein called ARF, which acts as a fail-safe mechanism to protect against cancer, also prevents regeneration in mammals, a study published August 6 inĀ Cell Stem Cell suggests. ARF backs up Rb, an important anticancer protein, by limiting the ability of mature cells to divide… read more

Will the Next Ice Age Be Permanent?

November 13, 2008

The world may be witnessing the final stages of a 50-million-year transition from a planet with a persistent warm climate and scant polar ice to one with greatly expanded ice sheets at both poles, two climatologists suggest in Nature.

The Nature paper goes on to propose that humans, as long as they have a technologically powerful society, would be likely to avert such a slide into a long big… read more

India’s elephant in the room: Weak patent laws

May 10, 2007

India’s fast-growing biotech business has the potential to be one of the driving forces behind its enviable 8 percent GDP growth, and a government estimate sees the industry increasing 15-fold over the next eight years.

Mapping the Physical And Mental Universes

August 5, 2004

If the manual of life is encoded in our DNA, where do we look to find the blueprint of consciousness? This was a subject that fascinated Francis Crick, who, along with James Watson, discovered the double-helix structure of DNA 50 years ago.

Engrossed in the mysterious relationship between mind and body, Crick later felt impelled to turn his attention from matter to mind and from biology to philosophy –… read more

Quantum calibration paves way for super-secure communication

November 18, 2008

A new approach to calibrating quantum mechanical measurement has allowed scientists to calibrate a detector that can sense the presence of multiple individual photons.

This means that devices that rely on information being transmitted via light, such as the fiber-optic technologies used in everyday communications, could detect the safe arrival of that light energy with an unprecedented level of accuracy, leading to ultra-secure communications technologies in the future via… read more

Google’s goal to organise your daily life

May 23, 2007

Google envisages a day when it can tell people what jobs to take and how they might spend their days off, says CEO Eric Schmidt.

The race to accumulate the most comprehensive database of individual information has become the new battleground for search engines, to enable personalized ads, which would command higher rates.

Artificial Retina

August 19, 2004

A retinal prosthesise implanted in the eye could restore the sight of millions.

It would use a digital video camera mounted on a pair of glasses, coupled via a miniature transmitter to a retinal implant array underneath the retina. The array’s electrodes would stimulate surviving nerve cells in response to images from the camera, providing a small patch of vision.

The Boston Retinal Implant Project hopes to test… read more

Silicon nanocrystals break miniaturization barrier for memory chips

September 1, 2010


Rice University scientists have created the first two-terminal memory chips that use only silicon to generate nanocrystal wires as small as 5 nanometers — far smaller than circuitry in even the most advanced computers and electronic devices. The technology breakthrough promises to extend the limits of miniaturization subject to Moore’s Law, and should be easily adaptable to nanoelectronic manufacturing techniques.

Jun Yao, a graduate student in Rice… read more
