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

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

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

August 1, 2012

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

Growing number of chemicals linked with brain disorders in children

214 human neurotoxicants now identified -- many widely used and disseminated extensively in the global environment

MRI-scans---mercury

Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children — such as autism, attention-deficit hyperactivity disorder, and dyslexia — according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai. The researchers say a new global prevention strategy to control the use of these substances is urgently needed.

The report was published online February… read more

How to build a million-qubit quantum computer

December 4, 2012

Hybrid dual-quantum dot/superconducting resonator device

A team led by Princeton‘s Associate Professor of Physics Jason Petta has developed a new method that could eventually allow engineers to build a working quantum computer consisting of millions of quantum bits (qubits).

Quantum computers take advantage of the strange behaviors of subatomic particles like electrons. By harnessing electrons as they spin, scientists could use the particles to form the basis for a… read more

Transparent solar cells for windows that generate electricity

July 23, 2012

ucla_transparent_solar_cell

Researchers from UCLA and California NanoSystems Institute have developed a new transparent solar cell, giving windows in homes and other buildings the ability to generate electricity.

This new kind of polymer solar cell (PSC) produces energy by absorbing more near-infrared light but is less sensitive to visible light, making the cells nearly 70% transparent to the human eye. They use a near-infrared light-sensitive polymer and silver nanowire composite films as… read more

Hovering moon base may be on NASA’s horizon

NASA is considering plans for a hovering moon base parked in orbit about 60,000 kilometers from the moon’s far side, at Lagrange point 2 (EML-2)New Scientist reports.

There, the combined gravity of Earth and the moon would tug on a spacecraft with exactly the force needed for it to hover near the moon without spending fuel. This might assist human missions to an asteroid or to Mars… read more

University of Copenhagen researchers and an international team have for the first time mapped telomerase, an enzyme with a rejuvenating effect on cell aging.

This is one of the results of a major research project involving more than 1,000 researchers worldwide, four years of hard work, DKK 55 million from the EU, and blood samples from more than 200,000 people.

It is the largest collaboration project… read more

“I’ve experienced both sides” of the privacy debate on Google Glass, Nick Bilton writes in The New York Times.

But other gadgets have plenty of privacy-invading potential too, he says. Memoto, a tiny, automatic camera that looks like a pin you can wear on a shirt, can snap two photos a minute and later upload it to an online service.

Apple is… read more

Disney Research 3-D printer can combine fabrics, wiring

April 20, 2015

layered fabric 3D printed objects-ft

A team from Disney Research, Carnegie Mellon University and Cornell University have devised a 3-D printer that layers together laser-cut sheets of fabric to form soft, squeezable objects such as phone cases and toys. These objects can have complex geometries and incorporate circuitry that makes them interactive.

“Today’s 3-D printers can easily create custom metal, plastic, and rubber objects,” said Jim McCann, associate… read more

A tiny computer attracts a million tinkerers

January 31, 2013

The Raspberry Pi Model B is a credit–card sized computer board that plugs into a TV. It’s a miniature ARM–based PC that can perform many of the functions of a large desktop PC such as spreadsheets, word–processers and games. It also plays High–Definition videos. (Credit: Raspberry Pi)

Almost one million $35 Raspberry Pi computers have shipped since last February, capturing the imaginations of educators, hobbyists and tinkerers around the world, The New York Times reports.

The Raspberry Pi — about 3 inches by 2 inches and less than an inch high — was intended to replace the expensive computers in school science labs. For less than the price of a new keyboard, a… read more
