New rechargeable flow battery enables cheaper, large-scale energy storage

Design may support widespread use of solar and wind energy
August 20, 2013

(credit:

MIT researchers have engineered a new rechargeable flow battery that doesn’t rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.

The palm-sized prototype generates three times as much power per square centimeter as other membraneless systems — a power density that is an order of magnitude higher than that of many lithium-ion batteries… read more

Northwestern Medicine researchers have developed a biodegradable nanoparticle  that stealthily delivers an antigen that tricks the immune system into stopping its attack on myelin and haltd a model of relapsing remitting multiple sclerosis (MS) in mice, according to new research.

The nanoparticles can also be applied to other immune-mediated diseases, including Type 1 diabetes, food allergies, and asthma.

Newcastle University researchers say they have discovered how neurons age.

Experts previously identified the molecular pathway that reacts to cell damage and stems the cell’s ability to divide, known as cell senescence. However, in cells that do not have this ability to divide, such as neurons in the brain and elsewhere, little was understood of the aging process.

Now scientists at Newcastle University, led by Professorread more

Moore’s Law threatened by lithography woes

October 9, 2012

Moore’s Law is losing steam due to delayed introduction of next-generation extreme ultraviolet lithography (EUV), said experts at the 2012 International Symposium on Extreme Ultraviolet Lithography, EE Times reports.

EUV systems need light sources that are nearly 20 times more powerful than the ones used today to lay down patterns on next-generation chips that target sizes as small as 14 nm. Lithography experts said that… read more

Wireless device converts ‘lost’ microwave energy into electric power

November 8, 2013

Power harvesting split-ring resonator

Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels.

The device wirelessly converts a microwave signal to direct current voltage that is capable of recharging a cell phone battery or other small electronic device.

It operates on a principle similar to… read more

Self-driving cars in 2019, report says

August 23, 2012

kpmg_self_driving_cars

Autonomous cars will be in showrooms as early as 2019, or maybe even sooner, according to a report released by KPMG and the Center for Automotive Research,

The report’s authors explain that “sensor-based technologies” and “connected-vehicle communications” need to converge. Essentially, cars need to be able to communicate with other vehicles on the road so they don’t bash into each other.

They also need the ability to sense… read more

New flexible classroom design

February 8, 2013

Classroom (credit:

Researchers at North Carolina State University have developed a classroom design that gives instructors increased flexibility in how to teach their courses and improves accessibility for students, while slashing administrative costs.

The new flexible approach acknowledges the fact that students are now bringing their own laptops to class. The classrooms also include mobile infrastructure, where whiteboards, desks and tables can be reconfigured according to the… read more

FDA clears first autonomous telemedicine robot for hospitals

Now doctors can provide patient care from anywhere in the world via a telemedicine solution. But what happens to nursing jobs, and how will patients react to a giant robotic machine?

Robot-for-hospitals

iRobot Corp., a leader in delivering robotic solutions, has announced that its RP-VITA Remote Presence Robot has received 510(k) clearance by the U.S. Food and Drug Administration (FDA) for use in hospitals. RP-VITA is the first autonomous navigation remote presence robot to receive FDA clearance.

RP-VITA is a joint effort between iRobot and InTouch Health. The robot combines the latest in autonomous navigation and mobility… read more

How to connect your home appliances to the Internet of Things

Is it really smart to connect smart grids to the Internet?
November 13, 2012

sigfox

French startup SigFox thinks it can help usher in a second mobile Internet boom by connecting millions of low-power sensors worldwide to the Internet, MIT Technology Review reports.

SigFox is focused on connecting cheap sensors and “dumb” home appliances to the Internet. The goal is to make all kinds of appliances and infrastructure, from power grids to microwave ovens, smarter by letting them share data.… read more

New brain gene gives us edge over apes

November 15, 2012

human_and_ape

An international team led by the University of Edinburgh has discovered a new gene called miR-941 that helps explain how humans evolved evolved from apes by playing a crucial role in human brain development, and may shed light on how we learned to use tools and language.

The researchers say it is the first time that a new gene — carried only by humans and not by apes —… read more

Possible breakthrough using graphene for solar cells

Graphene retains its exceptional conductivity and transparency when coated with silicon film
October 14, 2013

Researchers at the Helmholtz-Zentrum Berlin (HZB) Institute for Silicon Photovoltaics have shown that graphene retains its impressive set of properties when it is coated with a thin silicon film.

These findings may allow for entirely new possibilities to use graphene in thin-film photovoltaics.

Graphene has extreme conductivity and is completely transparent while being inexpensive and nontoxic. This would makes it a perfect candidate material… read more

Why Google’s self-driving car may save lives — if all cars are computer-driven

May 11, 2012

The technology behind Google’s self-driving car represents a potential leap forward in auto safety.

More than 30,000 people are killed each year in crashes despite huge advances in auto safety. The overwhelming majority of those crashes are caused by human-driver error.

Computer driven cars could reduce traffic deaths by a very significant degree, said David Champion, head of auto testing at Consumer Reports, but only if all cars are… read more

European scientists from six institutes and two universities have developed an online platform where robots can learn new skills from each other worldwide — a kind of “Wikipedia for robots.”

The objective is to help develop robots better at helping elders with caring and household tasks.

“The problem right now is that robots are often developed specifically for one task”, says René van de Molengraft, TU/e researcher and… read more

Defense Secretary Leon E. Panetta warned Thursday that the United States was facing the possibility of a “cyber-Pearl Harbor” and was increasingly vulnerable to foreign computer hackers who could dismantle the nation’s power grid, transportation system, financial networks and government, The New York Times reports.

He said he was reacting to increasing aggressiveness… read more
