Interesting read.

When Hippocrates first described cancer around 400 B.C., he referred to the disease’s telltale tumors as “karkinos” — the Greek word for crab. The “Father of Western Medicine” likely noted that cancer’s creeping projections mirrored certain crustaceans, and the tumors ‘ characteristic hardness resembled a crab’s armored shell.

Later, scientists added another attribute: Tumors are hypoxic. That is, they grow so large and dense that they exclude blood vessels, causing a lack of oxygen in their cores. But what role these characteristics play in the development of cancer has remained a mystery.

Adding flouride to drinking water is a safe and effective measure for preventing tooth decay, National Health and Medical Research Council analysis finds.

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.

About time.

Who watches the drones? Other drones.

The existence of worms holes has been long debated and has even become a staple in science fiction.
