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

Here’s how to best secure your data now that the NSA can crack almost any encryption

October 27, 2013

NSA

The latest Snowden-supplied bombshell shook the technology world to its core on Thursday: The NSA can crack many of the encryption technologies in place today, PC World reports — a day after Pew reported that 90 percent of Internet users have taken steps to avoid surveillance in some way.

PC World recommends several open-source encryption tools, such as… read more

Toyota has unveiled a new assistant robot alled the Human Support Robot (HSR),  designed to help the disabled live more independently, Gizmag reports.

The HSR can be controlled using a simple graphical user interface via tablet. It can also wear a tablet atop its head, which would allow caregivers and family members to communicate with the robot’s owner over Skype or other services.

Unlike recent telepresence robots,… read more

Elderly mice suffering from age-related heart disease saw a significant improvement in cardiac function after being treated with the FDA-approved drug rapamycin for just three months.

The research, led by a team of scientists at the Buck Institute for Research on Aging, shows how rapamycin impacts mammalian tissues, providing functional insights and possible benefits for a drug that has been shown to extend the lifespan… read more

Growing number of chemicals linked with brain disorders in children

214 human neurotoxicants now identified -- many widely used and disseminated extensively in the global environment

Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children — such as autism, attention-deficit hyperactivity disorder, and dyslexia — according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai. The researchers say a new global prevention strategy to control the use of these substances is urgently needed.

The report was published online February… read more

Laser could trigger rain and lightning

April 22, 2014

Illustration of a high-intensity laser dressed with a secondary laser that helps provide fuel to extend the distance of the primary beam.

Researchers at the University of Central Florida’s College of Optics & Photonics and the University of Arizona have further developed a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning.

The solution: surround the beam with a second beam to act as an energy reservoir, sustaining the central beam to greater distances than previously possible. The secondary “dress” beam… read more

Facebook, CNN, and the rise of social voting

July 13, 2012

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

Southampton engineers build a Raspberry Pi supercomputer

September 12, 2012

raspberry_pi_supercomputer_5

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

Hovering moon base may be on NASA’s horizon

November 16, 2012

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

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

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

Google’s plan to take over the world

June 18, 2013

Google isn’t just the backbone of the Internet anymore, writes Steve Kovach at Business Insider.

“It’s rapidly becoming the backbone of your entire life, all thanks to data you’re voluntarily giving up to a private company based on your Web searches, photos, Gmail messages, and more. …

“It’s the most apparent in Google Now, a voice-powered personal assistant that launched on Android phones last year.” [...]
