It might be possible to restore lost memories

Memories not stored in synapses, neurobiologist finds

New UCLA research indicates that lost memories can be restored, offering hope for patients in the early stages of Alzheimer’s disease.

For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses.

“Long-term memory is not… read more

Events in the future seem closer than those in the past

We say that time flies, it marches on, it flows like a river — our descriptions of time are closely linked to our experiences of moving through space.

Now, new research suggests that the illusions that influence how we perceive movement through space also influence our perception of time. The findings provide evidence that our experiences of space and time have even more in common than previously… read more

A virus that kills cancer: the cure that’s waiting in the cold

September 5, 2012

oncolytic_virus

Professor Magnus Essand has developed a virus that may kill cancer cells, The Telegraph reports.

Cheap to produce, the virus is exquisitely precise, with only mild, flu-like side-effects in humans. But Ad5[CgA-E1A-miR122]PTD is never going to be tested to see if it might also save humans, due to lack of funding.

Brainwave training boosts brain network for cognitive control

October 25, 2012

eeg_amplitide_change_during_feedback

Researchers at  University of Western Ontario and the Lawson Health Research Institute have found that functional changes within a key brain network occur directly after a 30-minute session of noninvasive, neurofeedback training.

Background

Dysfunction of this cognitive-control network has previously been implicated in a range of brain disorders including attention deficit hyperactivity disorder, schizophrenia, depression, and post-traumatic stress disorder.

During neurofeedback, users learn to… 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

Scanadu has announced updates to its Scanadu Scout, the “first medical Tricorder,” a prototype device designed to measure vital signs; and the launch of an indiegogo campaign.

A first-edition Scout can be reserved on indiegogo and will be available in March 2014.

The Scout is sold as an exploratory tool. “By helping us collect data, we can file our application to the FDA for market… read more

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

June 12, 2013

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

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

Skyscraper-style carbon-nanotube chip design ‘boosts electronic performance by factor of a thousand’

December 9, 2015

A multi-campus team led by Stanford engineers Subhasish Mitra and H.-S. Philip Wong has developed a revolutionary high-rise architecture for computing (Stanford University)

Researchers at Stanford and three other universities are creating a revolutionary new skyscraper-like high-rise architecture for computing based on carbon nanotube materials instead of silicon.

In Rebooting Computing, a special issue (in press) of the IEEE Computer journal, the team describes its new approach as “Nano-Engineered Computing Systems Technology,” or N3XT.

Suburban-style chip layouts create long commutes and regular traffic jams in electronic circuits, wasting time and energy, they note.… read more

The Human Brain Project has officially begun

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

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

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
