North Dakota State University. researchers have developed a new way of embedding traceable chips within “smart” paper — raising the possibility of banks and governments guarding against counterfeiting and even tracking the usage of paper money, IEEE Spectrum reports.

A record-setting blast of gamma rays from a dying star in a galaxy about 3.6 billion light-years away has wowed astronomers around the world — the highest-energy light ever detected from such an event.
At 3:47 a.m. EDT, April 27, Fermi’s Gamma-ray Burst Monitor (GBM) triggered on an eruption, designated GRB 130427A, of high-energy light in the constellation Leo.
The Fermi Large Area Telescope (LAT) recorded one gamma ray… read more

The CAD file is downloadable* at DEFCAD, operated by Defense Distributed — a “makeshift response to Makerbot Industries’ decision to censor files uploaded in good faith at Thingiverse, specifically firearms-related files.”
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
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

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
