In 2012, the US Navy initiated the SSL Technology Maturation (SSL-TM) program, in which industry teams led by BAE Systems, Northrop Grumman, and Raytheon, among others, competed to develop a shipboard laser with a beam power of 100 kW to 150 kW by 2016.

Boosting beam power further—to something like 200 kW or 300 kW—could permit a laser to counter at least some ASCMs. Even stronger beam powers—on the order of at least several hundred kW, if not one megawatt (MW) or more—could improve a laser’s effectiveness against ASCMs (Anti-Ship Cruise Missile) and enable it to counter ASBMs (Anti-Ship Ballistic Missile.

By 2020, it should be possible to demonstrate a 250–500 kW laser weapon system, one appropriate for deployment on current surface combatants and capable of being a game changer in the Navy’s struggle to address the growing A2/AD challenge.

Munich. BMW has become the first car manufacturer to introduce a mixed reality system into vehicle development that has been devised entirely using components from the computer games industry. This offers some significant advantages over the VR systems that have existed to date, and is the first step towards making virtual reality a very real part of many developer workstations in the not-too-distant future.

The adoption of this computer system makes it possible to save a great deal of time and effort, especially during the early stages of development. VR investigations could previously only be conducted at costly specialised facilities. By incorporating consumer electronics, the developers gain an unprecedented degree of flexibility, because any modifications can be implemented and tested very quickly. In addition to this, developers around the globe will be able to take part in the decision-making process from their own office without having to travel too far. Only once the draft designs have been approved with the help of the 3D headsets will they actually be built for further testing.

BMW has been employing VR systems in the development process since the 1990s. It is now reaffirming its pioneering status by systematically implementing technology from a sector which has not previously been the focal point of industrial applications. Since this spring, components from the computer games industry have been allowing engineers and designers to immerse themselves more and more often in virtual worlds that are increasingly realistic. The shorter innovation cycles of consumer electronics result in a far wider scope of functions together with lower costs. This thereby enables more vehicle functions to be translated to a VR model in ever more realistic fashion. It is furthermore possible to scale the system to many different developer workstations with little effort.

The U.S. Marine Corps has launched a cyberspace warfare group to help man, equip and train the military branch’s cyber mission teams to conduct defensive and offensive operations.

The service branch said March 25 the Marine Corps Cyberspace Warfare Group was officially activated during a ceremony held March 25 at Fort Meade in Maryland.

The CRISPR/Cas9 gene-editing platform may need a little bit more tweaking before it can be used as an effective antiviral, reports a study published April 7 in Cell Reports. Researchers who used CRISPR/Cas9 to mutate HIV-1 within cellular DNA found that while single mutations can inhibit viral replication, some also led to unexpected resistance. The researchers believe targeting multiple viral DNA regions may be necessary for the potential antiviral aspect of CRISPR/Cas9 to be effective.

Upon entry into a cell, HIV’s RNA genome is converted into DNA and becomes entwined with the cellular DNA. From here, CRISPR/Cas9 can be programmed to target a DNA sequence and cleave viral DNA. The problem is that HIV is notoriously good at surviving and thriving with new mutations, so while many viruses are killed by the targeted approach, those that escape the CRISPR/Cas9 treatment become more difficult to target.

“When we sequence the viral RNA of escaped HIV, the surprise is that the majority of the mutations that the virus has are nicely aligned at the site where Cas9 cleaves the DNA, which immediately indicates that these mutations, instead of resulting from the errors of viral reverse transcriptase, are rather introduced by the cellular non-homologous end joining machinery when repairing the broken DNA,” says senior study author Chen Liang, Senior Investigator at the Lady Davis Institute at the Jewish General Hospital and the Associate Professor of Medicine at the McGill University AIDS Centre.

The theoretical results of a piece of international research published in Nature, whose first author is Ion Errea, a researcher at the UPV/EHU and DIPC, suggest that the quantum nature of hydrogen (in other words, the possibility of it behaving like a particle or a wave) considerably affects the structural properties of hydrogen-rich compounds (potential room-temperature superconducting substances). This is in fact the case of the superconductor hydrogen sulphide: a stinking compound that smells of rotten eggs, which when subjected to pressures a million times higher than atmospheric pressure, behaves like a superconductor at the highest temperature ever identified. This new advance in understanding the physics of high-temperature superconductivity could help to drive forward progress in the search for room-temperature superconductors, which could be used in levitating trains or next-generation supercomputers, for example.

Superconductors are materials that carry electrical current with zero electrical resistance. Conventional or low-temperature ones behave that way only when the substance is cooled down to temperatures close to absolute zero (−273 °C o 0 degrees Kelvin). Last year, however, German researchers identified the high-temperature superconducting properties of hydrogen sulphide which makes it the superconductor at the highest temperature ever discovered: −70 °C or 203 K.

Nice read that ties Quantum properties such as tunneling to everything around us including our own blood supply in our bodies.

Objects of the quantum world are of a concealed and cold-blooded nature: they usually behave in a quantum manner only when they are significantly cooled and isolated from the environment. Experiments carried out by chemists and physicists from Warsaw have destroyed this simple picture. It turns out that not only does one of the most interesting quantum effects occur at room temperature and higher, but it plays a dominant role in the course of chemical reactions in solutions!

We generally derive our experimental knowledge of quantum phenomena from experiments carried out using sophisticated equipment under exotic conditions: at extremely low temperatures and in a vacuum, isolating quantum objects from the disturbing influence of the environment. Scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw, led by Prof. Jacek Waluk and Prof. Czeslaw Radzewicz’s group from the Faculty of Physics, University of Warsaw (FUW), have just shown that one of the most spectacular quantum phenomena — that of tunneling — takes place even at temperatures above the boiling point of water. However, what is particularly surprising is the fact that the observed effect applies to hydrogen nuclei, which tunnel in particles floating in solution. The results of measurements leave no doubt: in the studied system, in conditions typical for our environment, tunneling turns out to be the main factor responsible for the chemical reaction!
