Meyers-Rat-Main-Image

Two Bucknell University professors are working with a U.S. Department of Defense contractor to develop faster and more sophisticated technology and methods to detect land mines. The team has devised a system to train rats to recognize and respond to the explosives.

The rats will be outfitted with miniature backpacks and wireless transmitters that track their positions and movements. During the first part of their training, the… read more

Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.

The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet.

The whole system cost under £2,500 (excluding switches) and… read more

Biological transistor enables computing within living cells

Stanford University bioengineers have taken computing beyond mechanics and electronics into the living realm of biology by creating the “transcriptor” — a biological transistor made from DNA and RNA.

In electronics, a transistor controls the flow of electrons along a circuit. Similarly, a transcriptor controls the flow of a specific protein, RNA polymerase, as it travels along a strand of DNA.

“Transcriptors are the… read more

Professor Tom Kirkwood has demolished a string of misconceptions about the aging process with a groundbreaking study into the health of more than 1,000 older people in the 85-plus generation.

His study, the largest of its kind ever undertaken, has proved revealing on several fronts:

  • Life expectancy is increasing by about two years every decade.
  • People

60 billion planets in our galaxy could sustain water, life: researchers

July 2, 2013

A planet with clouds and surface water orbits a red dwarf star in this artist’s conception of the Gliese 581 star system.

A new study by University of Chicago and Northwestern University researchers that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs, the most common type of stars in the universe.

In our Milky Way galaxy alone, 60 billion planets may be orbiting red dwarf stars in the habitable zone.

Current data from NASA’s… read more

Weak repetitive transcranial magnetic stimulation (rTMS) applied to mice can shift abnormal neural connections to more normal locations in the brain, researchers from The University of Western Australia and the Université Pierre et Marie Curie in France have demonstrated.

The discovery has implications for treatment of nervous system disorders related to abnormal brain organization, such as depression, epilepsy, and tinnitus.

World’s largest offshore wind farm generates first power

November 2, 2012

worlds-largest-offshore-windfarm

The first power has been produced at the London Array Offshore Wind Farm, DONG Energy, E.ON and Masdar have announced .

The 630MW scheme, located in the Thames Estuary, will be the world’s largest offshore wind farm, with construction on schedule to be finished by the end of the year.

The 175 turbines will produce enough power to supply over 470,000 UK homes with electricity.

Here’s how to best secure your data now that the NSA can crack almost any encryption

October 27, 2013

NSA

The latest Snowden-supplied bombshell shook the technology world to its core on Thursday: The NSA can crack many of the encryption technologies in place today, PC World reports — a day after Pew reported that 90 percent of Internet users have taken steps to avoid surveillance in some way.

PC World recommends several open-source encryption tools, such as… read more

Network theory suggests consciousness is global in the brain

March 16, 2015

The black dots correspond to the 264 areas of the cerebral cortex that the researchers probed, and the lines correspond to the increased strength of the functional connections between each of these brain areas when subjects consciously perceive the target. The "hotter" colors are associated with stronger connections. This figure illustrates that awareness of the target corresponds to widespread increase in the strength of functional connections. (credit: Marois/Godwin).

Vanderbilt University researchers have found evidence that awareness or consciousness results from widespread communication across sensory and association areas of the cortex — challenging previous hypotheses that changes in restricted areas of the brain were responsible for producing awareness.

“Identifying the fingerprints of consciousness in humans would be a significant advancement for basic and medical research, let alone its philosophical implications on the underpinnings of the human… read more

Just add water: a portable hydrogen fuel cell

Battery dead in the middle of a phone call and you left your charger home, or worse, you’re on a camping trip. Sound familiar?

No prob, just grab some nanosilicon powder, mix with water, and zap: instant hydrogen fuel to generate recharge current — thanks to University at Buffalo researchers, who have discovered that super-small particles of silicon react with water to produce hydrogenread more

Lifespan-extending drug given late in life reverses age-related heart disease in mice

Elderly mice suffering from age-related heart disease saw a significant improvement in cardiac function after being treated with the FDA-approved drug rapamycin for just three months.

The research, led by a team of scientists at the Buck Institute for Research on Aging, shows how rapamycin impacts mammalian tissues, providing functional insights and possible benefits for a drug that has been shown to extend the lifespan… read more

The Human Brain Project has officially begun

Competing teams announced for $1 million prize incentive to create an artificial liver

September 16, 2014

The U.S. organ wait list has grown rapidly, while the number of organ donors has stagnated --- but the true need is almost 10x larger than the official waiting list suggests: 900,000 annual deaths are preventable by liver transplantation (credit: New Organ)

New Organ — a collective initiative for tissue engineering and regenerative medicine — announced today (Sept. 16) the initial six teams competing for the $1 million New Organ Liver Prize, a global prize competition launched in December 2013 and  sponsored by the Methuselah Foundation, a biomedical charity.

The award will go to “the first team that creates a regenerative or bioengineered solution that keeps a large animal… read more

Panasonic develops highly efficient artificial photosynthesis system generating organic materials from carbon dioxide and water

panasonic_artificial_photosynthesis

Panasonic has developed an artificial photosynthesis system that converts carbon dioxide (CO2) to organic materials by illuminating with sunlight at a world’s top efficiency of 0.2%.

The efficiency is on a level comparable with real plants used for biomass energy. The key to the system is the application of a nitride semiconductor which makes the system simple and efficient.

This development will be a foundation… read more
