Continued destruction of Earth’s plant life places humankind in jeopardy, say researchers

July 15, 2015

Earth-space battery. The planet is a positive charge of stored chemical energy (cathode) in the form of fossil and nuclear fuels and biomass. As this energy is dissipated by humans, it eventually radiates as heat toward the chemical equilibrium of deep space (anode). The battery is rapidly discharging without replenishment.

Unless humans slow the destruction of Earth’s declining supply of plant life, civilization like it is now may become completely unsustainable, according to a paper published recently by University of Georgia researchers in the Proceedings of the National Academy of Sciences.

“You can think of the Earth like a battery that has been charged very slowly over billions of years,” said the study’s lead author,… read more

Gerald Burgess, a University of Leicester lecturer in clinical psychology, has described treating an individual who suffered a “Memento/Before I Go to Sleep“-style anterograde amnesia memory loss after a treatment at a dentist — “like nothing we have ever seen before.”

Since the one-hour root-canal treatment, during which the a 38-year-old man from the UK was given a local anesthetic, the individual cannot remember anything… read more

The U.S. Patent and Trademark Office has awarded a patent (US 9,068,562) to Boeing engineers and scientists for a laser- and nuclear-driven airplane engine.

“A stream of pellets containing nuclear material such as Deuterium or Tritium is fed into a hot-stop within a thruster of the aircraft,” Patent Yogi explains. “Then multiple high powered laser beams are all focused onto the hot-spot. The pellet is… read more

Instead of heating or cooling your whole house, imagine a fabric that will keep your body at a comfortable temperature — regardless of how hot or cold it actually is.

That’s the goal of an engineering project called ATTACH (Adaptive Textiles Technology with Active Cooling and Heating) at the University of California, San Diego, funded with a $2.6M grant from the U.S. Department of Energy’sread more

3D printers could revolutionize food processing in the next 10 to 20 years, said Hod Lipson, Ph.D., a professor of engineering at Columbia University, speaking at IFT15: Where Science Feeds Innovation.

“The technology is getting faster, cheaper, and better by the minute. Food printing could be the killer app for 3D printing.”

Lipson, who is co-author of Fabricated: The New World of 3D Printing, said 3D… read more

Using graphene-based film for efficient cooling of electronics

A method for efficiently cooling electronics using graphene-based film — with a thermal conductivity capacity four times higher than copper — has been developed by researchers at Chalmers University of Technology. The film can be attached to computer chips and other silicon-based electronic components.

Electronic systems available today accumulate a great deal of heat, mostly due to the ever-increasing demand on functionality. Getting rid of excess… read more

Gene therapy restores hearing in deaf mice

Clinical trials of gene therapy for humans expected within 5 to 10 years

Patients with hearing loss will one day have their genome sequenced and their hearing restored by gene therapy, says Jeffrey Holt, PhD,  a scientist in the F.M. Kirby Neurobiology Center at Boston Children’s Hospital and an associate professor of Otolaryngology at Harvard Medical School.

A proof-of-principle study published by the journal Science Translational Medicine takes a step in that direction, restoring hearing in deaf mice. Clinical trials of gene therapy for… read more

IBM announces first 7nm node test chips

IBM Research has announced the semiconductor industry’s first 7nm (nanometer) node test chips, which could allow for chips with more than 20 billion transistors, IBM believes — a big step forward from today’s most advanced chips, made using 14nm technology.

IBM achieved the 7 nm node through a combination of new materials, tools and techniques, explained Mukesh Khare, VP, IBM Semiconductor Technology Research in a blog post.… read more

Transhumanist Party presidential candidate to drive ‘Immortality Bus’ across the U.S.

Don’t freak out if you see a 40-foot bus resembling a coffin sometime soon. It’s the “Immortality Bus” — a “pro-science symbol of resistance against aging and death” to be driven across the U.S. by futurist and 2016 Transhumanist Party presidential candidate Zoltan Istvan, along with scientists and supporters.

“We’re trying to spread a culture that looks positively at indefinite human lifespans,” Istvan told… read more

How to visually determine thickness at one-nanometer resolution by eye

European scientists have taught volunteers in an experiment how to determine the thickness of a titanium dioxide thin film only a few nanometers thick by simply observing the color it presents under under highly controlled, precise lighting conditions, according to Sandy Peterhänsel, University of Stuttgart, Germany and principal author of an open-access paper in the journal Optica.

The optical properties of thin films are the… read more

University of California, Berkeley, physicists have used graphene to build lightweight ultrasonic loudspeakers and microphones, enabling people to mimic bats or dolphins’ ability to use sound to communicate and gauge the distance and speed of objects around them.

More practically, the wireless ultrasound devices complement standard radio transmission using electromagnetic waves in areas where radio is impractical, such as underwater, but with far greater fidelity than current ultrasound or sonar… read more

Crowdsourcing neurofeedback data

Crowdsourcing brain data with hundreds of adults could be a new frontier in neuroscience and could lead to new insights about the brain
