Researchers have defined what it means for time translation symmetry to be spontaneously broken in a quantum system, and show with analytical arguments and numerical simulations that this occurs in a large class of many-body-localized driven systems with discrete time-translation symmetry. In 2012 Nobel laureate Frank Wilczek first proposed the idea of time crystals. He …
The head of the Chinese air force, Ma Xiaotian, stated that China is developing a new long-range bomber. “We are now developing a new generation of long-range bomber, and you’ll see it in the future,” Ma told the Global Times without elaborating. China has been ramping up research into advanced new military equipment, including submarines, …
More than two billion people could be at risk from Zika virus outbreaks in parts of Africa and Asia, according to scientists writing in The Lancet Infectious Diseases. Populations in India, Indonesia and Nigeria are some of the most vulnerable to transmission, the researchers said. They used data on air traveller numbers to help model …
South Korea has renewed calls to deploy nuclear-powered submarines on the battlefront, refueling debate about using the advanced weapons against North Korean ballistic missile threats. The communist state marked its first successful firing of a submarine-launched ballistic missile last week, undermining South Korea’s resolve to neutralize threats via land-based missile defense systems. “The SLBM launch …
Spacex plans to use a lot more carbon fiber components instead of aluminum in their rockets. SpaceX aims to hold down expenses by reusing rockets and spacecraft. Originally, the company made rockets mostly out of aluminum to keep costs low, using carbon fiber only for a few parts, such as connecting joints. Japanese materials maker …
The fourth low production rate copy of the Chinese J-20 stealth fighter has been spotted The J-20 will fly at up to 1305 mph The appearance of LRIP aircraft suggests that the type is nearing introduction into service with the People’s Liberation Army Air Force. A number of J-20s have been seen on satellite imagery …
The United States military had problems in the Vietnam war but introduced precision guided weapons in the first Gulf war. Russia’s air force cannot match the United States in terms of the number of 5th generation planes. This primarily matters in terms of a WW3 or pre-WW3 showdown. However, Russia’s nuclear weapons and conventional capability …
America, Japan and China are racing to be the first nation to make nuclear energy completely renewable. The hurdle is making it economic to extract uranium from seawater, because the amount of uranium in seawater is truly inexhaustible. James Conca at Forbes describes the latest developments with uranium seawater extraction. James has some update from …
Researchers propose a novel combination therapy consisting of an agent for chelating redox-active metals (Fe2+) and an antioxidant to reduce damage caused by residual oxygen free radicals, in addition to resveratrol, a modulator of AMPK and sirtuin pathways (nuclear transcription). The addition of resveratrol may have the capacity to increase activity of the NAD+- dependant …
Pratt and Whitney are working on a block one improvement to the F135 engine (used on the F-35 stealth fighter) which will offer between a 7% and 10% improvement in thrust, as well as between 5% and 7% better mission fuel burn, and is undergoing testing now. Although higher thrust and better fuel burn have …
Tens of millions more tonnes of fish have been taken from the seas than are recorded in official statistics, suggests a huge and controversial project aiming to estimate the ‘true catch’ of the world’s fishing industry. The work is detailed in a paper in Nature Communications by fisheries researchers Daniel Pauly and Dirk Zeller of …
