Single-molecule motor sits on a single-atom ball bearing

Can be run forward or in reverse, depending on where electrons are injected
December 31, 2012

The base of the device holds a Ru atom, and the five-armed device can rotate on top of it (credit:

Researchers have created a reversible rotor that sits atop a ball bearing — a single ruthenium atom, Ars Technica reports.

The base of the system involves a boron atom that coordinates three ringed structures that are chemically similar to the bases of DNA. Nitrogens at a corner of these ringed structures coordinate the ruthenium atom, placing it at the peak of a three-sided pyramid.

The ruthenium atom acts… read more

Six medical innovations are poised to transform the way we fight disease, The Wall Street Journal reports.

  • Surgeons at Boston Children’s Hospital have developed a way to help children born with half a heart to essentially grow a whole one — by marshaling the body’s natural capacity to heal and develop.
  • Oxford Nanopore Technologies has unveiled the first of a generation of tiny DNA sequencing devices that

Adafruit, the kit-based electronics retailer and promoter of hobbyist engineering, is aiming to teach electronics to a younger demographic, using puppets, says Wired.

Their new online show, titled Circuit Playground, will teach the essentials of electronics and circuitry to children through kid-friendly dolls.

As a learning companion, Adafruit has also recently produced the coloring book E is for Electronics, and will carry … read more

Is growth over?

Global growth from the current industrial revolution (computers, the web, mobile phones) is slowing — especially in advanced-technology economies, and long-term economic growth may grind to a halt, Robert J. Gordon, Stanley G. Harris Professor in the Social Sciences and Professor of Economics at Northwestern University, has argued.

Now economist Paul Krugman counters in The New York Times that we are moving toward a… read more

Synaptic electronic circuits that learn and forget like neural processes

December 27, 2012

nanoionic device

Rui Yang, Kazuya Terabe and colleagues at the National Institute for Materials Science (NIMS), and the International Center for Materials Nanoarchitectonics (MANA) in Japan and at the California NanoSystems Institute/UCLA have developednanoionic” (processes connected with fast ion transport in all-solid-state nanoscale systems) devices capable of a broad range of neuromorphic and electrical functions.

Background

Such a device would allow for fabrication of on-demand configurable circuits,… read more

‘Neuristor’: memristors used to create neuron-like behavior

December 27, 2012

neuron-640x480

HP Labs researchers may have figured out a way to create a chip that generates neuron-like spikes (sharp signal pulses), using a combination of memristors and capacitors to create a spiking output pattern, Ars Technica reports.

Neurons encode information in the pattern and timing of  spikes. The researchers used a simplified model of neurons based on sodium-potassium ion channels to turn the neuron on and off.… read more

A high-resolution nanoscale window to the live biological world

December 27, 2012

vtech_nanoscale_window

Investigators at the Virginia Tech Carilion Research Institute have invented a way to directly image biological structures at nanometer-resolution in their natural habitats (a liquid environment).

The technique is a major advancement toward the ultimate goal of imaging biological processes in action at the atomic level.

The technique uses two silicon-nitride microchips with windows etched in their centers and pressing them together until only… read more

Thiel Fellowship applications open until December 31

Program awards $100,000 grants to innovative, driven young people with creative ideas who want to make a difference for the world
December 27, 2012

thiel_fellowship

Applications for the Thiel Foundation’s 20 Under 20 fellowship program for 2013 are due by 11:59 P.M. (UTC–12) on December 31, 2012.

Thiel Fellowships consist of separate grants of $100,000 to 20 people under 20 years old, so that they can leave the classroom and pursue innovation. In addition to the financial support, Thiel Fellows are mentored by hundreds of highly accomplished entrepreneurs, scientists, investors, thinkers, and innovators of the Thiel Network.… read more

Advanced humanoid Roboy to be ‘born’ in nine months

December 26, 2012

roboy

Meet Roboy, “one of the most advanced humanoid robots,” say researchers at the Artificial Intelligence Laboratory of the University of Zurich.

Their 15 project partners and over 40 engineers and scientists are constructing Roboy as a tendon-driven robot modeled on human beings (robots usually have their motors in their joints, giving them that “robot” break-dance look), so it will move almost as elegantly as a… read more

What will your next body be like?

“Many engineers, including me, think that some time around 2050, we will be able to make very high quality links between the brains and machines. … If your mind is so well connected, you could inhabit a new body, without having to vacate your existing one,” suggests futurologist Ian Pearson.

“Using a detachable brain is one option, or not to put a brain in at all, using empty immobile husks that… read more

How to ID people exposed to ionizing radiation

Research could lead to a blood test that triages victims after a radiation-related incident
December 24, 2012

DNA damage

Research conducted by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) could lead to a blood test that detects if a person has been exposed to radiation, measures their dose, and separates people suffering from inflammation injuries — all in a matter of hours.

Background: dealing with a nuclear incident

There’s a reason emergency personnel train for the aftermath of… read more

Low-cost, transparent, flexible, light solar cells

MIT researchers develop a new approach using graphene sheets coated with nanowires
December 24, 2012

Illustration shows the layered structure of the new device, starting with a flexible layer of graphene, a one-atom-thick carbon material. A layer of polymer is bonded to that, and then a layer of zinc-oxide nano wires (shown in magenta), and finally a layer of a material that can extract energy from sunlight, such as quantum dots or a polymer-based material.

MIT researchers have produced a new kind of photovoltaic cell based on sheets of flexible graphene coated with a layer of nanowires.

The approach could lead to low-cost, transparent and flexible solar cells that could be deployed on windows, roofs or other surfaces.

The new approach is detailed in a report published in the journal Nano Letters, co-authored by MIT postdocs Hyesung Park and… read more
