UC Berkeley researchers have developed an new method for inserting genes into retina cells that is easier and more effective, It could greatly expand gene therapy to help restore sight to patients with blinding diseases ranging from inherited defects like retinitis pigmentosa to degenerative illnesses of old age, such as macular degeneration.

Unlike current treatments, the new procedure delivers genes to hard-to-reach cells throughout the entire retina,… read more

The number of new cases in Liberia is “increasing exponentially,” according to a statement Monday by the World Health Organization (WHO), and “many thousands of new cases are expected in Liberia over the coming 3 weeks.”

There’s also a 20% chance that that the Ebola epidemic (as it is now called) will reach the U.S. by the end of September, according to experts writing in… read more

Flip of a single molecular switch makes an old brain young

March 8, 2013

A cultured neuron with projecting dendrites studded with sites of communication between neurons, known as dendritic spines (Yale University)

The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability.

Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.

Scientists have long known that the young and old brains are very different. Adolescent brains… read more

The touch-screen generation

touch-screen generation

Young children — even toddlers — are spending more and more time with digital technology. What will it mean for their development?

The Atlantic magazine explores this trend in its cover story, “The Touch-Screen Generation.”

Rooftop solar, other renewables make 9GW of baseload fossil fuels no longer needed in Australia

August 1, 2013

AGL Energy, one of the big three power utilities in Australia, says that 9,000MW of fossil-fuel baseload capacity needs to be taken out of the national electricity market (NEM) to bring it back into balance, RenewEconomy reports.

That assessment of 9,000MW equates to nearly one-third of the country’s baseload generation — a sure sign that renewables, and in particularly rooftop solar, are changing the dynamics of the… read more

An easy, low-cost way to get into 3D printing

January 7, 2014

MakerBot Mini

If you’ve been thinking about getting into 3D printing, the compact MakerBot Replicator Mini 3D printer, just introduced at CES, could make it easy and affordable at $1,375 (available spring 2014).

It’s limited to printing objects around 4 x 4 x 4 inches, but the company claims it’s easy to use, with no 3D skills needed. You can download models from the free MakerBot Printshop and Thingverse,… read more

A boost for quantum reality

May 9, 2012

In a controversial paper in Nature Physics, theorists claim they can prove that wavefunctions — the entity that determines the probability of different outcomes of measurements on quantum-mechanical particles — are real states.

The paper is thought by some to be one of the most important in quantum foundations in decades. The authors say that the mathematics leaves no doubt that the wavefunction is not just a statistical tool, but rather, a… read more

Japanese researchers at the National Institute for Materials Science and Shinshu University have developed a way to shrink capacitors — key components that store energy — further, which could accelerate the development of more compact, high-performance next-gen electronic devices. The study appears in the journal ACS Nano.

Takayoshi Sasaki and colleagues note that current technology has almost reached its limit in terms of materials and processing, which in turn… read more

With 120 million monochrome and 5 million color receptors, the eye and brain are able to do what even our most advanced cameras are unable to, according to computer graphics pioneer Tim Sweeney of Epic Games.

With a resolution of about 30 megapixels, the human eye is able to gather information at about 72 frames per second, which explains why many gamers debate the need for frame rates higher than… read more

Mystery deepens: Mike Treder has crossed over into Canada

March 22, 2012

Michael Treder, the transhumanist leader and IEET fellow who disappeared during a visit to Detroit, has crossed the border into Canada and hasn’t been seen since, according to Detroit police spokeswoman Sgt. Eren Stephens, the Detroit Free Press reported today (March 22).

Treder, 58, from Brooklyn, N.Y., was last heard from March 14, according to his family, who said he left all of his possessions in his room at… read more

Ultra-high-res 100,000 dpi color printing

April 12, 2013

Variation in post size and spacing in the metal array alters which incoming wavelength of light (red, green or blue) is reflected back (K. Kumar et al./A*STAR)

Commercial laser printers typically produce pin-sharp images with spots of ink about 20 micrometers apart, resulting in a resolution of 1,200 dots per inch (dpi).

By shrinking the separation to just 250 nanometers — 80 times smaller, a research team at A*STAR can now print images at an incredible 100,000 dpi, the highest possible resolution for a color image.

These images could be used… read more

The self-driving car logs more miles on new wheels

Members of the Google self-driving car team will soon start using the cars solo (rather than in pairs) for things like commuting to work, says Google Official Blog.

Our vehicles, of which about a dozen are on the road at any given time, have now completed more than 300,000 miles of testing. They’ve covered a wide range of traffic conditions, and there hasn’t been a single accident… read more

Max Planck Institute (MPI) for Medical Research scientists are developing a complete circuit diagram of the brain of the mouse using an electron microscope to make fine extensions of almost every single neuron visible.

Most axons are less than one micron thick, some even smaller than 100 nanometers. “The electron microscope is the only microscope with a high enough resolution to enable individual axons lying next to each other… read more
