Endosonographic imaging is more accurate than surgery for staging of lung cancer, but a new study suggests it has no effect on rates of survival.

A federal appeals court questioned during a hearing Tuesday whether the city of Berkeley is unduly discouraging customers from buying cell phones by requiring retailers to warn them about the possible radiation effects of carrying switched-on phones close to their bodies.

Berkeley’s ordinance, challenged by the cell phone industry, requires dealers to notify customers that the federal government sets radiation standards for the phones and that a user may be exposed to levels above those standards by carrying a cell phone in a pocket or tucked into a bra when the device is connected to a wireless network.

U.S. District Judge Edward Chen of San Francisco allowed the law to take effect in January, saying the warning was based on research and guidelines by the Federal Communications Commission.

Definitely a big deal.

I look forward to the day when everything lives and adapts as well as interacts in their environments. Buildings, machines, autos, planes, etc. Last month we read about the living buildings that DARPA is focused on that utilizes synthetic cells which enables buildings and other structures to self repair themselves much like human cells do.

Definitely glad to see more and more people jump on the Singularity path.

Not a complete list — where are al the various joint ventures & start ups that are also in play; however, what about all those Laboratories (Governmental, Universities, and joint venture related labs) such as Los Alamos or ORNL or MIT or USC, and what about all of the governmental agencies (NASA, DoD, etc.), and how about all of those special programs like DARPA. And, this is only the US not to mention what has been happening in China, Australia, Canada, UK, Spain, Germany, Russia, Singapore, etc.

Nice article to use as a starting list only; itmissed many, many other companies, labs, universities, and governments who are really leading most of the progress forward in QC. Some start up to add — Qubitekk, QC Ware, Rigetti Computing to just name 3 off the top of my head. Article is missing a lot in its list.

Google, Microsoft, and Airbus are investing in quantum computing. In all, we identified 18 corporates developing the tech, or partnering with startups like D-Wave to do so, and what they hope to achieve.

We illustrate how it is possible to calculate the quantum gravitational effects on the spectra of primordial scalar/tensor perturbations starting from the canonical, Wheeler-De Witt, approach to quantum cosmology. The composite matter-gravity system is analysed through a Born-Oppenheimer approach in which gravitation is associated with the heavy degrees of freedom and matter (here represented by a scalar field) with the light ones. Once the independent degrees of freedom are identified the system is canonically quantised. The differential equation governing the dynamics of the primordial spectra with its quantum-gravitational corrections is then obtained and is applied to diverse inflationary evolutions. Finally, the analytical results are compared to observations through a Monte Carlo Markov Chain technique and an estimate of the free parameters of our approach is finally presented and the results obtained are compared with previous ones.

WASHINGTON — Researchers have developed a new laser that makes it possible to measure electron transition energies in small atoms and molecules with unprecedented precision. The instrument will help scientists test one of the bedrock theories of modern physics to new limits, and may help resolve an unexplained discrepancy in measurements of the size of the proton.

The team will present their work during the Frontiers in Optics (FiO) / Laser Science (LS) conference in Rochester, New York, USA on 17 −21 October 2016.

“Our target is the best tested theory there is: quantum electrodynamics,” said Kjeld Eikema, a physicist at Vrije University, The Netherlands, who led the team that built the laser. Quantum electrodynamics, or QED, was developed in the 1940s to make sense of small unexplained deviations in the measured structure of atomic hydrogen. The theory describes how light and matter interact, including the effect of ghostly ‘virtual particles.’ Its predictions have been rigorously tested and are remarkably accurate, but like extremely dedicated quality control officers, physicists keep ordering new tests, hoping to find new insights lurking in the experimentally hard-to-reach regions where the theory may yet break down.

Electromagnetic waves created on a layer of organic molecules could provide the perfect on-chip light source for future quantum communication systems.

A team of scientists including researchers at Agency for Science, Technology and Research (A*STAR), Singapore, has captured tiny flashes of light from an ultrathin layer of organic molecules sandwiched between two electrodes that could replace lasers and LEDs as signal sources for future miniature, ultrafast quantum computing and light-based communication systems.

To investigate electromagnetic waves called plasmons, which skim along the interface between two materials, Nikodem Tomczak from the A*STAR Institute of Materials Research and Engineering and colleagues collaborated with Christian A. Nijhuis from the National University of Singapore to construct a junction consisting of a layer of thiol molecules on a metal electrode and liquid gallium-indium alloy as a top electrode.
