Bio-inspired Assembly of Nanoparticle Building Blocks

November 30, 2006
V-shaped amphiphilic molecules containing gold nanoparticles form cylindrical micelles when exposed to water

Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature’s oldest known chemical innovations — the self-assembly of lipid membranes that surround every living cell.

Researchers believe the new method will allow them to create a wide variety of useful materials, including extra-potent cancer drugs and more… read more

Transforming Thoughts Into Deeds

January 15, 2004

A brain-computer interface created by Cyberkinetics called BrainGate could help patients with no mobility to control a computer, a robot, or eventually their own rewired muscles, using only their thoughts.

Babbage nanomachine promises low-energy computing

March 26, 2010

Boston University researchers have created a nanoscale mechanical logic gate using vibrating silicon strips that could form the basis of future nanocomputers.

Rocket-powered racing plane takes flight

July 30, 2008

The Rocket Racing League’s first racing plane took to the skies on Tuesday.

Billed as a NASCAR for the skies, the league hopes to pit rocket-powered planes against each other on a 3D track.

DNA-like ice ‘seen’ inside carbon nanotubes

December 13, 2006

Nanoscale ice formations resembling the double helices of DNA will form when water molecules are frozen inside carbon nanotubes, detailed computer simulations suggest.

Nanotechnology Takes On Cancer

January 30, 2004

The NIH Roadmap for Medical Research includes nanomedicine research for cancer therapy.

For example, the Center For Biologic Nanotechnology at the University of Michigan is developing dendrimers (molecules shaped like spheres and made up of nanoscale polymers in a very specific pattern) that can create smart-therapeutic nanodevices used to treat disease. One type seeks out and recognizes only cancer cells. Another type can diagnose what type of cancer it… read more

Carbon nanotubes broken down by white blood cells

April 6, 2010

A team of Swedish and American scientists has shown for the first time that carbon nanotubes can be broken into water and carbon dioxide by an enzyme — myeloperoxidase (MPO) — found in white blood cells.

This enzyme is expressed in certain types of white blood cell (neutrophils), which use it to neutralize harmful bacteria.

Carbon nanotubes were once considered biopersistent and potentially toxic.

“This means that… read more

A first in integrated nanowire sensor circuitry

August 5, 2008

Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world’s first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics made of different crystalline materials.

Their method can be used to reproduce numerous such devices with high uniformity.

Robots of the Future

December 22, 2006

DARPA’s Urban Challenge, safety issues, artificial muscles, a multifunctional home robot, and Microsoft involvement will be the five key developments in robots in 2007.

Superconductors, Quantum Mechanics and Nanotech to the Rescue

February 11, 2004

A trio of high technologies — superconductors, quantum mechanics and nanotech — may allow cancer specialists to spot tumors so small they elude today’s best imaging methods.

A “Superconducting QUantum Interference Device,” or SQUID, lets oncologists and surgeons locate previously injected tumor-specific nanoparticles that act like submicroscopic cancer-detection beacons.

Motivated Multitasking: How the Brain Keeps Tabs on Two Tasks at Once

April 16, 2010

The brain can handle two tasks by distributing them between the two hemispheres of the brain, assuming it perceives a worthy reward for doing so, but with large dual-task costs, researchers at the French National Institute for Health and Medical Research have found.

The study also explains why people tend to prefer binary options, such as yes-or-no questions and if-then statements: the frontopolar cortex (which organizes pending goals while… read more

Insufficient vitamin D linked to chronic pain, increased risk of death

August 12, 2008

Low levels of vitamin D have been linked to chronic pain in women, and increased risk of death for all people.

Researchers at Johns Hopkins analyzed a diverse sample of 13,000 people and found a 26% increased risk of death for participants in the lowest quartile of vitamin D levels. This is consistent with other studies that have linked low levels of vitamin D to diabetes, cancer,… read more

Nanoscale Cubes and Spheres

January 4, 2007

University of Minnesota have developed a new process for the production of nanoscopic cubes and spheres of silicon dioxide. Instead of building their particles from smaller units, they used the controlled disassembly of larger, lattice-like structures.

Porous nano-objects with defined sizes and structures are particularly interesting, for example, as capsules for enzymes, a means of transport for pharmaceutical agents, or building blocks for larger nanostructures.

Earth sows its seeds in space

February 23, 2004

Deep-frozen spores that spread life in space (the Panspermia concept) could survive if they can escape the Sun’s gravity more quickly. And that might happen if the rocks they sit on are first ground to dust, says William Napier, an astronomer at the Armagh Observatory in Northern Ireland.

The pressure of sunlight can quickly blow grains this small out of the solar system and such a grain could travel… read more

2010 Humanity+ Summit

April 26, 2010

The H+ Summit, a two- day event that explores how humanity will be radically changed by technology in the near future, is scheduled for June 12-13 at Harvard University.

Speakers include Ray Kurzweil, Aubrey de Grey (“Hype and anti-hype in academic biogerontology research: a call to action”), Alex Lightman (“The Rise of Citizen-Scientists in the Eversmarter World”), David Orban (“Intelligence Augmentation, Decision Power, And The Emerging Data… read more
