By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond — the nitrogen-vacancy center — in a method that allows for more unified control than conventional processes.
The method is also more versatile, and opens up the possibility of exploring new solid-state quantum systems.
“In contrast to conventional electronics, we developed an all-optical scheme… read more
Scientists from The Children’s Hospital of Philadelphia and the Sloan-Kettering Institute for Cancer Research have led a study team that has manipulated human stem cells into producing types of brain cells known to play important roles in neurodevelopmental disorders such as epilepsy, schizophrenia and autism.
The new model cell system allows neuroscientists to investigate normal brain development, as well as to identify specific disruptions in biological signals… read more
Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.
“This new method is a game changer,” says Jaenisch, who is also a professor of biology at MIT. “We can now make a… read more
A quantum internet capable of sending perfectly secure messages has been running at Los Alamos National Labs for the last two and a half years, MIT Technology Review reports.
One of the dreams for security experts is the creation of a quantum internet using quantum cryptography that allows perfectly secure communication based on the powerful laws of quantum mechanics.
The researchers created a quantum network based around… read more
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
