Working from his garden shed, Israeli inventor Izhar Gafni has invented a $20 cardboard bike, says The Telegraph.

The solid tires are made of reconstituted rubber from old car tires and some proprietary materials have been added for water protection and other purposes.

“This is a real game changer,” said Nimrod Elmish, Gafni’s business partner. ”It changes … the way products are manufactured and shipped, it causes factories to… read more

A challenge facing designers of future computer chips

November 8, 2012

The total conductance per unit area is similar for both tungsten (W) and gold (Au). However, by joining the two highly conducting metals, one finds a conductance density that is about 4 times lower of either material individually. (Credit: David J. Olivera et al./PNAS)

To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.

Researchers at at McGill University General Motors R&D, have shown that electrical current could be drastically reduced when wires from two dissimilar metals meet. The surprisingly sharp reduction in current reveals a significant challenge… read more

Ivanpah solar electric generating system connects to grid

September 30, 2013

ivanpah featured

The Ivanpah Solar Electric Generating System in California’s Mojave Desert produced its first output of energy when the first of three towers was synchronized last week to the power grid for the first time.

Power generated from Ivanpah will first go to Pacific Gas and Electric (PG&E), followed by Southern California Edison in the coming months.

Ivanpah is the largest solar thermal plant in the… read more

When does your baby become conscious?

April 19, 2013

New research shows that babies display glimmers of consciousness and memory as early as 5 months old, Science Now reports.

Studies on adults show a particular pattern of brain activity: When your senses detect something, such as a moving object, the vision center of your brain activates, even if the object goes by too fast for you to notice. But if the object remains in your visual… read more

Elon Musk has released a video demonstrating SpaceX’s new custom 3D design interface, inspired by Iron Man.

It includes use of Leap Motion control, free-standing glass projections (from Iron Man), 3D projections using glasses, and the Occulus Rift VR headset.

After generating and manipulating the 3D model, Musk then 3D-prints an actual titanium metallic rocket-engine part from the model.

“I believe we are on the… read more

Paging Dr. Watson: artificial intelligence as a prescription for health care

“It’s not humanly possible to practice the best possible medicine. We need machines,” said Herbert Chase, a professor of clinical medicine at Columbia University and member of IBM’s Watson Healthcare Advisory Board, Wired Science reports.

“A machine like [IBM's Watson], with massively parallel processing, is like 500,000 of me sitting at Google and Pubmed, trying to find the right information.”

Yet though Watson is clearly a powerful tool,… read more

Human v 2.0: Ray Kurzweil vs. Hugo de Garis

October 24, 2006

“Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v2.0.

“It’s predicted that by 2029 computer intelligence will equal the power of the human brain. Some believe this will revolutionise humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to… read more

Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new… read more

DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.

DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more

How unconscious processing improves decision-making

February 15, 2013

New brain imaging research from Carnegie Mellon University provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision making. Published in the journal Social Cognitive and Affective Neuroscience, the study found that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task.

Evidence that photosynthesis efficiency is based on quantum mechanics

January 17, 2014

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis, published in the journal Nature Communications (open access).

The majority of light-gathering macromolecules are composed of chromophores (responsible for the color of molecules) attached to proteins, which carry out the first step of photosynthesis, capturing… read more

NASA mulls plan to drag asteroid into moon’s orbit

NASA is mulling over a plan to build a robotic spacecraft to grab a small asteroid and place it in high lunar orbit, according to researchers with the Keck Institute for Space Studies in California.

The mission would cost about $2.6 billion and could be completed by the 2020s, New Scientist reports.

The Obama administration has said it also wants to send astronauts to a near-Earth asteroid. One… read more

Supplement added to a standard diet improves health and prolongs life in mice

Representative photographs from blinded histopathological analysis of kidney, liver, and lung panels for mice on standard diet (SD) and SRT1720 supplementation

Activating a protein called sirtuin 1 extends lifespan, delays the onset of age-related metabolic diseases, and improves general health in mice. The findings, which appear online February 27 in the Cell Press journal Cell Reports, point to a potentially promising strategy for improving health and longevity.

Sirtuin 1, or SIRT1, is known to play an important role in maintaining metabolic balance in multiple tissues, and studies in… read more
