Two separate teams of researchers working on DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program, led by the University of Stuttgart in Germany and IBM’s Almaden Research Center, have developed a nanoscale magnetometer that enables magnetic resonance imaging (MRI) with sufficient resolution to measure as few as 10,000 protons in a volume of only 125 cubic nanometers, which approaches the level of individual protein molecules. … read more
A fluorescent dye that enables high-resolution (about 1 micron) 3D images of the cerebral vascular system has been synthesized by researchers at the Laboratoire de Chimie (CNRS) in France in collaboration with the Institut des Neurosciences (Université Joseph Fourier).
The “Lem-PHEA chromophore” dye fluoresces in the red-near infrared region biological transparency window using two-photon absorption and can pass through the skin. It features solubility in biological… read more
MicroGen has developed a “piezo-MEMS” (piezoelectric microelectromechanical systems) device that gathers ambient vibrations and converts them into electrical energy.
Vibration causes a tiny flap in the device to swing back and forth, generateing electrical current that charges an ultra-capacitor (a thin-film battery).
The “BOLT micro-power module” (MPM) begins commercial-scale production in summer 2013. It was researched and developed by the company at the… read more
Vehicles, robots and other autonomous devices could soon collaborate with humans, thanks to researchers at MIT who are developing systems capable of negotiating with people to determine the best way to achieve their goals.
“In general, everything around us is getting smarter,” says Brian Williams, a professor of aeronautics and astronautics and leader of the Model-Based Embedded and Robotic Systems group… read more
Developer Michael DiGiovanni has revealed on github a beta android app for Google Glass called “Winky” that takes a photo — replacing the wordy “”OK, Glass, take a picture.”
“Users will be able to lifelog with little to no effort. It allows more pictures to be taken easily and to become a timeline of where you have been,” says Roundarch Isobar, where DiGiovanni is Emerging… read more
Painful finger-prick blood tests for diabetics could become a thing of the past, say physicists who have built a sensor that measures glucose in saliva.
Mitchell Lerner at the University of Pennsylvania and associates have developed just such a device, MIT Technology Review reports. Their glucose sensor is essentially a carbon nanotube-based transistor in which the nanotubes are coated with pyrene-1-boronic acid molecules that bind to glucose.… read more
Researchers from the RIKEN Center for Life Science Technologies have developed a new molecular imaging technology that enables them to visualize bio-metals and bio-molecules simultaneously in a live mouse.
This new technology will enable researchers to study the complex interactions between metal elements and molecules in living organisms.
Metal elements such as zinc, iron and copper are present in trace amounts in the body… read more
An Australian team led by researchers at the University of New South Wales is the first in the world to detect the spin, or quantum state, of a single atom using a combined optical and electrical approach.
This is a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers — connected via a quantum internet — closer to reality,… read more
Haptic devices — technologies that simulate the feel of an object — should be used as early as possible in children fitted with visual prosthetics, and also for older congenitally blind and late-blind people, George van Doorn and colleagues at Monash University suggest.
The haptic device can provide supplementary or redundant information that allows cross-referencing with the visual input from the prosthetic, they explain. This will help… read more
Scientists at Princeton University have used a 3D printer to create a functional ear that can “hear” radio frequencies up to microwave frequencies.
The researchers’ primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3D printing of cells and nanoparticles, followed by cell culture to combine a small coil antenna with cartilage, creating what they term… read more
Scientists at Albert Einstein College of Medicine of Yeshiva University have found that the hypothalamus of mice controls aging throughout the body.
Their discovery of a specific age-related signaling pathway opens up new strategies for combating diseases of old age and extending lifespan.
Background: the hypothalmus and inflammation
“Scientists have long wondered whether aging occurs independently in the body’s various tissues or if it… read more
‘Superlattice’ structure could give a huge boost to oxygen reaction in fuel cells, increasing their power potential.
New research at MIT could dramatically improve the efficiency of fuel cells, which are considered a promising alternative to batteries for powering everything from electronic devices to cars and homes.
Fuel cells make electricity by combining hydrogen, or hydrocarbon fuels, with oxygen. But the most efficient types, called solid… read more
University of Florida researchers have developed a “DNA nanotrain” that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body.
The nanotrains can cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter.
DNA nanotechnology holds great promise as a new way to deliver chemotherapy directly to cancer cells, but… read more
A new brain implant can warn of seizures minutes before they strike, enabling them to get out of situations that could present a safety risk, New Scientist reports.
With funding from NeuroVista, a medical device company in Seattle, Mark Cook of the University of Melbourne and his colleagues have developed a brain implant that consists of a small patch of electrodes that measure brain… read more
A new transistor capable of revolutionizing technologies for medical imaging and security screening has been developed by graphene researchers from the Universities of Manchester and Nottingham.
This is the first graphene-based transistor with bistable characteristics, which means that the device can spontaneously switch between two electronic states.
Such devices are in great demand as emitters of terahertz (trillions of oscillations per second, or thousands of gigahertz)… read more
