Self-driving vehicle technology is not yet at a stage that it can be authorized for use by the public for general driving, according to a U.S. Department of Transportation recommendation to state governments, PC World reports.

If a state decides to permit operation of self-driving vehicles other than for testing, at a minimum it should require that a person licensed to drive self-driving vehicles should be seated… read more

Scientists suggest that cancer is purely man-made

October 15, 2010

Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study by University of Manchester scientists has strongly suggested.

A study of remains and literature from ancient Egypt and Greece and earlier periods — carried out at the University of Manchester’s KNH Centre for Biomedical Egyptology and published in Nature — includes the first histological diagnosis of cancer in an Egyptian mummy.… read more

Professor Tom Kirkwood has demolished a string of misconceptions about the aging process with a groundbreaking study into the health of more than 1,000 older people in the 85-plus generation.

His study, the largest of its kind ever undertaken, has proved revealing on several fronts:

  • Life expectancy is increasing by about two years every decade.
  • People

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

How to build a million-qubit quantum computer

December 4, 2012

Hybrid dual-quantum dot/superconducting resonator device

A team led by Princeton‘s Associate Professor of Physics Jason Petta has developed a new method that could eventually allow engineers to build a working quantum computer consisting of millions of quantum bits (qubits).

Quantum computers take advantage of the strange behaviors of subatomic particles like electrons. By harnessing electrons as they spin, scientists could use the particles to form the basis for a… 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

Competing teams announced for $1 million prize incentive to create an artificial liver

September 16, 2014

The U.S. organ wait list has grown rapidly, while the number of organ donors has stagnated --- but the true need is almost 10x larger than the official waiting list suggests: 900,000 annual deaths are preventable by liver transplantation (credit: New Organ)

New Organ — a collective initiative for tissue engineering and regenerative medicine — announced today (Sept. 16) the initial six teams competing for the $1 million New Organ Liver Prize, a global prize competition launched in December 2013 and  sponsored by the Methuselah Foundation, a biomedical charity.

The award will go to “the first team that creates a regenerative or bioengineered solution that keeps a large animal… read more

Yes. A space elevator appears possible and space elevator infrastructure could indeed be built via a major international effort, a study conducted by experts under the auspices of the International Academy of Astronautics has found, Space.com writer Leonard David reports.

Two technologies pacing the development of the space elevator are an ultra-strong space tether and other space elevator components, and lightweight solar cells, according to study lead… read more

3D-printing human embryonic stem cells for drug testing, future replacement of human organs

New 3D printing process is first to print the more delicate (and more useful) hESCs

3D printing with embryonic stem cells (credit: )

A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.

The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more

CNN and Facebook have joined forces to make the “I’m Voting” Facebook app, which enables Facebook users to endorse candidates and issues, and to commit to voting.

If you use the app and commit to voting for someone, that information appears in your timeline, news feed, and real-time ticker.

During CNN’s political coverage this fall, CNN personalities will use the app to poll users on issues.

“We fundamentally… read more

Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.

The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet.

The whole system cost under £2,500 (excluding switches) and… read more

NASA is considering plans for a hovering moon base parked in orbit about 60,000 kilometers from the moon’s far side, at Lagrange point 2 (EML-2)New Scientist reports.

There, the combined gravity of Earth and the moon would tug on a spacecraft with exactly the force needed for it to hover near the moon without spending fuel. This might assist human missions to an asteroid or to Mars… read more
