MIT scientists said today they’ve just created one the strongest materials known (ten times stronger than steel, but also one of the lightest, with a density of just 5 percent of that of steel) by compressing and fusing flakes of graphene, a two-dimensional form of carbon.

In its two-dimensional form, graphene is thought to be the strongest of all known materials. But researchers until now have had a hard… read more

Scientists at the Agency for Science, Technology and Research’s (A*STAR) Institute of Molecular and Cell Biology (IMCB) have developed a method to generate human induced pluripotent stem cells (hiPSCs) from a single drop of finger-pricked blood.

The method also enables donors to collect their own blood samples, which they can then send to a laboratory for further processing. The easy access to blood samples using the new… read more

Samsung Electronics Co. said Sunday that it has successfully developed fifth-generation network (5G) core technology for the first time, allowing users to access faster data services expected to be available by 2020, Yonhap News Agency reports.

Under the new platform, users will be able to download and upload data at speeds of up to tens of gigabits per second (Gbps), compared to 75 megabits per second (Mbps)… read more

IBM unveils concept for a future brain-inspired 3D computer

October 20, 2013

IBM 3D computer

IBM has unveiled a prototype of a new brain-inspired computer powered by what it calls “electronic blood,” BBC News reports.

The firm says it is learning from nature by building computers fueled and cooled by a liquid, like our minds.

The human brain packs phenomenal computing power into a tiny space and uses only 20 watts of energy – an efficiency IBM is keen to match.… read more

Dear science fiction writers: stop being so pessimistic!

March 21, 2012

Neal Stephenson

Stephenson has seen the future — and he doesn’t like it.

Today’s science fiction, he argues, is fixated on nihilism and apocalyptic scenarios — think recent films such as The Road and TV series like “The Walking Dead.” Gone are the hopeful visions prevalent in the mid-20th century.

So in Fall 2011, Stephenson launched the Hieroglyph project to rally writers to infuse science fiction with… read more

University of Missouri (MU) researchers have developed a prototype of an efficient nuclear-energy-powered* battery that does not require recharging and could be a reliable energy source in automobiles and space vehicles.

Betavoltaics [a battery technology that generates electrical power from beta-particle radiation] has been studied as an energy source since the 1950s,” said Jae W. Kwon, an associate professor of electrical and computer engineering and… read more

New dimension to high-temperature superconductivity discovered

An unprecedented blend of intense magnetic and X-ray laser pulses produces surprising 3-D effect

The dream to push the operating temperature for superconductors to room temperature — leading to future advances in computing, electronics and power grid technologies — has just become more real.

A team led by scientists at the Department of Energy’s SLAC National Accelerator Laboratory has combined powerful magnetic pulses with some of the brightest X-rays on the planet, discovering a surprising 3-D arrangement of a material’s electrons that appears… read more

Fukushima plant spilling 300 tons of radioactive water every day into the sea since 2011

August 13, 2013

Mass contamination from major radiation exposure events, such as the meltdown at Japan’s Fukushima Daiichi nuclear power plant, require prompt treatment in the form of a pill, such as the treatment being developed at Berkeley Lab (credit: satellite image from Digital Globe)

Workers at the crippled Fukushima nuclear plant have told the Australian Broadcasting Company (ABC) that contaminated water has most likely been seeping into the sea since the disaster two-and-a-half years ago.

They do not have much faith in Tokyo Electric Power Company’s (TEPCO) ability to handle the situation and they claim another accident is inevitable.

Japan’s nuclear watchdog has described the leaks as a “state of… read more

Future Day event in Second Life

A Future Day event was held at Terasem Island in Second Life on March 1, with speakers Natasha Vita-More, Martine Rothblatt, Howard Bloom, Giulio Prisco, Adam A. Ford, and Ben Goertzel (via audio) and about 50 participants.

One of the projects discussed at the event was a Future Day film with positive and solar visions of the future (mostly interviews), for release at Future Day 2013… read more

‘This house wants to defeat aging entirely’: de Grey vs. Blakemore

April 24, 2012

Aubrey de Grey

Oxford University Scientific Society is hosting a debate on Wednesday, April, 25, 2012, addressing whether aging should be a target of decisive medical intervention — raising the possibility of substantial extension of human lifespan.

Dr. Aubrey de Grey will propose the motion, “This house wants to defeat aging entirely“ and Professor Colin Blakemore will be opposing. The debate will be chaired and moderated by Professor Sir Richard… read more

Beyond Second Life: more realistic avatars

May 21, 2013

avatar

Philip Rosedale, founder of once-popular virtual world Second Life, has created a new company called High Fidelity. As suggested by the video above and the blog, the company is developing more natural ways for avatars to communicate (with heads and hand movements, for example) and with low latency (faster response time).

“Imagine holding your phone and being able to twist and move your avatar’s hand.… read more

A NASA-funded new approach to power-beaming solar-power satellites has been developed by John Mankins, who led the first NASA solar-power-satellite development team in the 90s.

Called the SPS-ALPHA (Solar Power Satellite via Arbitrarily Large PHased Array), this “first practical solar-power satellite concept” uses a novel “biomimetic” approach.

Mankins said that this project would make possible the construction of huge platforms from tens of thousands of small elements that can deliver… read more

BioPen rewrites orthopedic implant surgery

Delivers live stem cells and growth factors at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue
December 13, 2013

biopen3

Australian researchers have developed a handheld “BioPen” that will allow surgeons to precisely design and deliver customized bone and other implant materials (live stem cells and growth factors) at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue.

Here’s how it works:

  1. Similar to a multi-material 3D printer, the BioPen delivers stem cells embedded in a biopolymer carrier (such as alginate, a seaweed extract), protected
