Space-based solar farms power up

February 28, 2013

spsalpha-concept

Space-based solar power (SBSP) has once again begun to attract attention with projects emerging in the US, Russia, China, India and Japan, among others. All are driven by increasing energy demands, soaring oil and gas prices, a desire to find clean alternatives to fossil fuels and by a burgeoning commercial space industry that promises to lower the cost of entry into space and spur on a host of new industries,… read more

The International Federation of Robotics tracked a 50 percent jump in purchases of advanced industrial robots by Chinese manufacturers in 2011, to 22,600 units, and now predicts that China will surpass Japan as the world’s largest market in two years, Technology Review reports.

Foxconn, said last July that the Taiwan-based manufacturing giant would add up to one million industrial robots to its assembly lines inside of three years.

A series of studies over two years with rodents exposed to radio frequency radiation (RFR) found low incidences of malignant gliomas (tumors of glial support cells) in the brain and schwannoma tumors in the heart.*

The studies were performed under the auspices of the U.S. National Toxicology Program (NTP).

Potentially preneoplastic (pre-cancer) lesions were also observed in the brain and heart of male rats… read more

Giant space telescope could image objects at far higher resolution than Hubble

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

They might be caused by common medications used to treat insomnia, anxiety, itching or allergies, according to Dr. Cara Tannenbaum, Research Chair at the Institut universitaire de gériatrie de Montréal (IUGM, Montreal Geriatric University Institute) and Associate Professor of Medicine and Pharmacy at the University of Montreal (UdeM).

Up to 90 percent of people over the age of 65 take at least one prescription medication. Eighteen… 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

A team of researchers at MIT, the University of Brasilia, and the University of British Columbia has engineered an antimicrobial peptide to wipe out many types of bacteria, including some that are resistant to most antibiotics.

A recent study from a U.K. commission on antimicrobial resistance estimated that by 2050, antibiotic-resistant bacterial infections will kill 10 million people per year if no new drugs are developed.

Limb regeneration: do salamanders hold the key?

June 24, 2014

Salamander (credit: UCL)

The secret of how salamanders successfully regrow body parts is being unravelled by University College London (UCL) researchers in a bid to apply it to humans.

For the first time, researchers have found that the “ERK pathway” must be constantly active for salamander cells to be reprogrammed, and hence able to contribute to the regeneration of different body parts.

The team identified a key… read more

FBI launches face recognition project

The Next Generation Identification program will include a nationwide database of criminal faces and other biometric data
September 10, 2012

As part of an update to the national fingerprint database, the FBI has begun rolling out facial recognition to identify criminals, New Scientist reports.

It will form part of the bureau’s long-awaited, $1 billion Next Generation Identification (NGI) program, which will also add biometrics such as iris scans, DNA analysis, and voice identification to the toolkit. A handful of states began uploading their photos as… read more

Moore’s Law threatened by lithography woes

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

Autonomous taxis could be cheaper and improve the environment, says Berkeley Lab study

Self-driving car concept (credit: Google)

It’s the year 2030. A fleet of driverless taxis roams throughout your city, ready to pick you up and take you to your destination at a moment’s notice. As a result, greenhouse gases are now 63 to 82 percent lower than with a privately owned hybrid car and 90 percent lower than a 2014 gasoline-powered private vehicle. …

Those numbers are from a new study from Lawrence Berkeley National Laboratory… 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

Slowing down the aging process by ‘remote control’

September 10, 2014

Activating a gene called AMPK in the nervous system induces the anti-aging cellular recycling process of autophagy in both the brain and intestine. Activating AMPK in the intestine leads to increased autophagy in both the intestine and brain. Matthew Ulgherait, David Walker and UCLA colleagues showed that this 'inter-organ' communication during aging can substantially prolong the healthy lifespan of fruit flies. (Credit: Matthew Ulgherait/UCLA)

UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems.

Working with fruit flies, the life scientists activated a gene called AMPK that is a key energy sensor in cells; it gets activated when cellular energy levels are low.

Increasing the amount of AMPK in fruit flies’ intestines increased their lifespans by about 30 percent… read more
