How Geckos Stick — New Find May Lead to New Glue

August 29, 2002
Copyright (c) 2000 Kellar Autumn

A team of biologists and engineers has cracked the molecular secrets of the gecko’s unsurpassed sticking power, opening the door for engineers to fabricate prototypes of dry, adhesive microstructures that work even underwater or in a vacuum.

The gecko’s amazing climbing ability, the researchers found, depends on weak molecular attractive forces called van der Waals forces (electrodynamic forces that operate over very small distances but bond to nearly any… read more

Sony latest to demo videogame motion-sensing controller

June 3, 2009

Sony on Tuesday demonstrated a prototype motion-sensing videogame controller.

A camera tracks the player’s movements, and software translates their movements to those of onscreen characters.

Star Trek-like ‘Phraselateor’ device helps police communicate

January 17, 2008

VoxTec’s Phraselator PDA-like device, developed through DARPA for use by soldiers in Afghanistan and Iraq, is now being used by police in California, Florida, and Nevada.

Thin skin will help robots ‘feel’

August 16, 2005

University of Tokyo researchers have developed a flexible artificial “skin” capable of sensing pressure and temperature that could give robots a humanlike sense of touch.

Future artificial skins could incorporate sensors also for light, humidity, strain or sound.

Human+: forecasting our future

April 18, 2011

Human Plus

The premise underlying Human+, an exhibition that opened April 15 at the Science Gallery at Trinity College Dublin, Ireland, is that the future is knowable.

Science Gallery director Michael John Gorman and his team have put together a fascinating array of objects, creations, and schemes, each of which explores some aspect of our engineered future.

Human+ is organized into five categories: “extended ecologies,” “authoring evolution,” “augmented abilities,” “non-human… read more

Microchips in the Blood

September 18, 2002

Many of the promised genomic drugs will be impossible to swallow as pills. Instead, they will have to be injected in minute quantities at precise intervals for months at a time. Just the job for an implantable syringe-on-a-chip. Researchers in this field refer to their goal as intelligent drug delivery. The intelligence is derived from a piece of silicon one centimetre square. Etched in the silicon is a matrix of… read more

Global IP Traffic to Increase Fivefold by 2013

June 10, 2009

By 2013, annual global IP traffic will reach 667 exabytes (667 billion gigabytes), according to the new Cisco Visual Networking Index (VNI) Forecast and Methodology, 2008-2013.

Video communications traffic will increase 10-fold from 2008 to 2013 and mobile data traffic will roughly double each year from 2008 to 2013, increasing 66 times between 2008 and 2013, with video accounting for 64 percent of it by 2013.… read more

DNA-Based Artificial Nose

January 23, 2008

Scientists working on “electric nose” technologies have found a way to quickly identify which DNA sequences are ideal for detecting a particular odor and to turn dried DNA into odor detectors.

The new platform, developed by Cogniscent (New Jersey) researchers, could be used to create a wide array of sensors using existing high-throughput molecular-biology equipment.

A simple way to cloak objects at microwave frequencies to improve transmission

October 8, 2012

sylinteri

A metal object can be made invisible to to electromagnetic radiation at microwave frequencies by approximately 70 per cent with the help of ordinary plastic, Aalto University researchers have shown.

In practical terms, this means that electromagnetic waves travelling, for example, between two antennas, do not detect an object located in their path, allowing the waves to travel the distance between them despite the obstacle, without any disruption… read more

On the Internet, Nobody Knows You’re a Bot

WinHoldEm, the first commercially available autoplaying poker software, wins real money while you sleep.

Data-intensive supercomputing

April 25, 2011

The amount of digital data generated by instruments such as DNA sequencers, cameras, telescopes, and MRIs is now doubling every 18 months, says Michael Norman, director of the San Diego Supercomputer Center (SDSC) at the University of California, San Diego (UCSD).

“Digital data is advancing at least as fast, and probably faster, than Moore’s Law,” said Norman…. But I/O (input/output) transfer rates are not keeping… read more

Darwin’s Theory May Explain Ill Health

October 11, 2002

Professor Randolph Nesse believes that conditions like heart disease, obesity and drug abuse can all be explained by the fact that the human body was not designed for the 21st Century. Nesse, professor of psychiatry at the University of Michigan, is one of the leading proponents of evolutionary or Darwinian medicine. Evolutionary medicine examines why some diseases still exist. According to Nesse, our bodies are designed to like things that… read more

Scientists invent 1.2nm molecular gear

June 16, 2009

A 1.2 nanometer molecular gear has been developed by scientists at the Agency for Science, Technology and Research.

Graphene photodetector speeds up light-to-electricity conversion

May result in faster data transmission and broadband photodetectors
April 15, 2015

90016_web

Researchers at MIT, UC Riverside, and ICFO have demonstrated a graphene-based photodetector that converts absorbed light into an electrical voltage in an extremely short time*.

The finding opens up a new path to ultra-fast optoelectronic (light to electricity and vice versa) conversion, which is essential for faster data transmission, and to photodetectors that operate over a broad range of frequencies.

To demonstrate… read more

Researchers Demonstrate Quantum Teleportation and Memory in Tandem

January 30, 2008

An international team of researchers created an experiment in which a quantum bit of information was transported across a distance of seven meters and briefly stored in memory, the first time that both quantum memory and teleportation have been demonstrated in a single experiment.
