Revving up the world’s fastest nanomotor

May 2, 2008
Tracks left by various types of speeding nanomotors (American Chemical Society)

Arizona State University researchers have developed a new generation of nanomotors with an average speed of 60 micrometers per second.

Existing catalytic nanomotors–made with gold and platinum nanowires and fueled with hydrogen peroxide–have top speeds of about 10 micrometers per second.

The new design adds carbon nanotubes to the platinum (boosting the average speed) and spikes the hydrogen peroxide fuel with hydrazine to increase the nanomotor’s… read more

Positioning atoms with lasers

June 19, 2001

An atomic conveyor belt/catapult that uses lasers to position individual atoms has been developed, researchers report in the June 15 issue of Science.

The German researchers use laser beams to retard fast-moving caesium atoms, which they hold in a trap of light and magnetic fields. The team then pulls these “cold” atoms out of the trap one at a time using two laser beams. They can stop… read more

Updated: Intel revamps teraflop MPU efforts

December 3, 2009

Intel Corp. has re-positioned its “tera-scale” processor R&D efforts, moving towards a more mainstream, x86-based multicore design instead of a proprietary technology.

Intel has demonstrated an experimental, 48-core processor–or “single-chip cloud computer” (because it resembles the organization of datacenters used to create a “cloud” of computing) based on a 45-nm process using high-k and metal-gate technology.

In the future, Intel’s “single-chip cloud computer” processor could be powerful enough… read more

Technology Research Advances of 2004

January 3, 2005

The profusion of technology research in 2004 includes a nanowire-based biochip developed by Harvard University researchers that detects single viruses, fault-tolerant chip design for nanowire logic circuits, a software program for designing computer chips made from DNA-assembled carbon nanotubes, and a scheme for storing light pulses using a photonic crystal that could make possible blazingly fast all-optical computer chips, quantum computers and quantum communications systems.

Nanowires for Displays

May 7, 2008

Researchers at the University of Illinois in Urbana Champaign have developed a simple process to grow upright copper nanowires on different surfaces.

The nanowire arrays could find use in field-emission displays, a new type of display technology that promises to provide brighter, more vivid pictures than existing flat-panel displays.

Scientists Make Embryos for Cells

July 11, 2001

Human embryos have been created in the lab for the sole purpose of harvesting their stem cells for the first time.

Until now, scientists had derived stem cells only from excess embryos donated from infertility treatments. In this case, the scientists approached donors and informed them that their eggs and sperm would be used to develop embryos for stem-cell research.

The work, conducted by researchers at the Jones… read more

Nanotubes as chemical reactor for nanoribbon production

August 10, 2011

Nanotube Reactor

Researchers at The University of Nottingham have pioneered a new method of using carbon nanotubes as nanoscale chemical reactors (containing chemical reactions).

Chemical reactions involving carbon and sulfur atoms held within a carbon nanotube lead to the formation of atomically thin strips of carbon (graphene nanoribbon) decorated with sulfur atoms around the edge.

The team has also discovered that nanoribbons — far from being… read more

Innovation: Making a map for everyone, by everyone

December 9, 2009

Crowdsourcing a map of the world and letting anybody edit it (via OpenStreetMap’s database) is now more feasible, thanks to some new user-friendly phone apps.

Video organizes paper

January 13, 2005

University of Washington researchers are working to more closely integrate the paper world with the world of electronic data.

Their system uses a computer and overhead video camera to track physical documents on a desk and automatically link them to appropriate electronic documents.

The paper-tracking system allows users to pinpoint the location of a given document within a stack of documents on the desktop. Users can find documents… read more

The Department of Defense is testing Virtual Iraq, a virtual-reality program for treating post-traumatic stress disorder.

Gates: AI for the billions

SEATTLE, Aug. 8 – The vast majority of Microsoft research–included in the firm’s $5.3 billion R&D budget for FY 2002–is for AI-related projects, Microsoft Chairman Bill Gates said, speaking at the International Joint Conference on Artificial Intelligence.
Microsoft’s research is focused on traditional AI areas, such as decision-making, learning, language, and speech recognition. “We are putting our money where our beliefs are: that these things will become real and allow… read more

Lifeboat Foundation 2009 Guardian Award goes to De Jager for Y2K warnings

December 16, 2009

Peter de Jager has been named the Lifeboat Foundation 2009 Guardian Award Winner, annually bestowed upon a respected scientist or public figure who has warned of a future fraught with dangers and encouraged measures to prevent them.

This award is in recognition of his 1993 warning that alerted the world to the potential Y2K disaster that might have occurred on January 1, 2000 and his efforts in… read more

Human Brain Design Gets a New Timetable

January 25, 2005

The genes that specify the architecture of the human brain seem to have started evolving faster some 20 million years ago, when the great apes split off from Old World monkeys.

The genes then doubled their speed of evolution after the human lineage parted ways with that of chimpanzees five million years ago.

The finding shows many different genes are involved in constructing the special features of the… read more

Green tea compounds beat OSA-related brain deficits

May 16, 2008

Chemicals found in green tea may be able to stave off the cognitive deficits that occur with obstructive sleep apnea (OSA), according to a study led by David Gozal, M.D., professor and director of Kosair Children’s Hospital Research Institute at the University of Louisville.

Parasite corrals computer power

August 31, 2001

Using the Internet itself as a computer, researchers have solved a mathematical problem with the unwitting assistance of machines in North America, Europe and Asia.The Notre Dame team exploited the Internet transmission control protocol (TCP). The TCP ensures accurate communication, using a “checksum” — a mathematical operation performed by sender and receiver. The two computers compare answers — if they differ, data has been corrupted in transit and they try… read more
