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

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

This Is how Dennis Tito plans to send people to Mars

February 28, 2013

Mars-Capsule_220213.m

If Dennis Tito has his way, two people will leave our planet in January 2018 and make a trip to Mars and back, with a quick flyby, SpaceRef reports.

The project is being spearheaded by a non-profit organization, the Inspiration Mars Foundation.

Tito’s mission will be facilitated by donors, not investors.

Tito and a group of coauthors from NASA and several aerospace companies… read more

Pupil dilation reveals sexual orientation in new Cornell study

August 7, 2012

Blue Eye Macro

There is a popular belief that sexual orientation can be revealed by one’s pupil dilation when viewing attractive people, but there has been no scientific evidence.

Now Cornell University researchers have confirmed it in an experiment, using a specialized infrared lens to measure pupillary changes in participants watching erotic videos.

Pupils widened most to videos of people who participants found attractive, thereby revealing where they were on… read more

Mayo Clinic researchers extend lifespan by up to 35 percent in mice

Researchers at Mayo Clinic have discovered that senescent cells — cells that no longer divide and accumulate with age — shorten lifespan by as much as 35 percent in normal mice.

Removing these aging cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects, the researchers found, writing Feb. 3 in Nature.

“Cellular senescence is a biological mechanism that functions as… read more

Memory capacity of brain is 10 times more than previously thought

The brain’s memory capacity is in the petabyte range, as much as the entire Web, data from the Salk Institute show; may lead to more energy-efficient computers
January 20, 2016

Salk scientists computationally reconstructed brain tissue in the hippocampus to study the sizes of connections (synapses). The larger the synapse, the more likely the neuron will send a signal to a neighboring neuron. The team found that there are actually 26 discrete sizes that can change over a span of a few minutes, meaning that the brain has a far great capacity at storing information than previously thought. Pictured here is a synapse between an axon (green) and dendrite (yellow). (credit: Salk Institute)

Salk researchers and collaborators have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The new work also answers a longstanding question as to how the brain is so energy efficient, and could help engineers build computers that are incredibly powerful but also conserve energy.

“This is a real bombshell in the field of neuroscience,” says … 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
