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

University of New South Wales (UNSW) solar researchers have converted more than 40% of the sunlight hitting a solar system into electricity, “the highest efficiency ever reported for sunlight conversion into electricity,” UNSW Scientia Professor and Director of the Australian Centre for Advanced Photovoltaics (ACAP) Professor Martin Green said.

“We used commercial solar cells, but in a new way, so these efficiency improvements are readily accessible to the solar… read more

University of Colorado Boulder researchers plan to update NASA officials this week on a revolutionary space telescope concept selected by the agency for study last June that could provide images up to 1,000 times sharper than the Hubble Space Telescope.

CU-Boulder Professor Webster Cash said the instrument package would consist of an orbiting space telescope with an opaque disk in front… read more

Kim Suozzi, diagnosed at age 21 with brain cancer while studying neuroscience at college, passed away Thursday, January 17, 2013 at age 23.

The Society for Venturism, a cryonics advocacy and support group, started a charity fund for her cryonic suspension in August of 2012 and through an overwhelming amount of support from the extreme life extension community, enough funds were raised for her to be cryopreserved with Alcor.… 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

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

May 11, 2012

Google_autonomous_vehicle

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

How teachers’ myths about the brain are hampering teaching

October 17, 2014

Photographs of the left and right midsagittal sections of Einstein’s brain with original labels (Falk et al., 2013), reproduced here with permission from the National Museum of Health and Medicine, Silver Spring, MD. The red circles indicate two breaches on each<br />
hemisphere of Einstein’s corpus callosum that have different shapes, which may have been introduced when the two hemispheres were<br />
separated in 1955.

Teachers in the UK, Holland, Turkey, Greece and China were presented with seven “neuromyths” and asked whether they believe them to be true.

A quarter or more of teachers in the UK and Turkey believe a student’s brain would shrink if they drank less than six to eight glasses of water a day, while around half or more of those surveyed believe a student’s brain is only 10 per… 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

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

Wi-Fi signal used to track moving humans — even behind walls

July 3, 2013

(credit: Christine Daniloff/MIT

‘Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory.are developing a system called “Wi-Vi” that transmits a low-power Wi-Fi signal and uses its reflections to track moving humans — even if they are in closed rooms or hiding behind a wall.

How it works

The researchers borrowed a technique called inverse synthetic aperture radar (ISAR), which has been… 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
