A group of scientists from NUST MISIS developed a ceramic material with the highest melting point among currently known compounds. Due to the unique combination of physical, mechanical and thermal properties, the material is promising for use in the most heat-loaded components of aircraft, such as nose fairings, jet engines and sharp front edges of wings operating at temperatures above 2000 degrees C. The results are published in Ceramics International.

EXECUTIVE SUMMARY: The US Department of Defense has been working with American companies for the past year on a project to develop a prototype for a portable nuclear microreactor, a device intended for use by the US military in security scenarios around the world. The US Department of Energy is also involved in the project, with the aim of providing electricity to remote sites that are difficult to link to the grid. The project thus represents a symbiosis between military and civilian technological development.

A symbiotic relationship between military and civilian aspects of technological development gained momentum in the US after the end of WWII. This was particularly visible among applications in the communication, computing, and aerospace fields, but was also present in the field of nuclear technology. Some technology projects were presented as dual-use in order to justify the cost of their development.

One example of nuclear energy symbiosis was the development of nuclear power-generating reactors. By 1956, more than a decade after the destruction of the Japanese cities of Hiroshima and Nagasaki by nuclear bombs, only the UK’s Calder Hall nuclear power plant, which had four reactors each producing 60 MW electricity (MWe), was in operation. However, as of December 2019, 443 nuclear power generators were operating worldwide, with a total output of 395 gigawatts electric (GWe)—an average output of nearly 900 MWe per reactor.

Twin shock waves produced by the galaxy’s central black hole could have inflated the gargantuan Fermi Bubbles about 6 million years ago, a new study suggests.

It is common knowledge that neural networks are very powerful and they can be used for almost any statistical learning problem with great results. But have you thought about why is this the case? Why is this method more powerful in most scenarios than many other algorithms?

Just as a literature buff might explore a novel for recurring themes, physicists and mathematicians search for repeating structures present throughout nature.

For example, a certain geometrical structure of knots, which scientists call a Hopfion, manifests itself in unexpected corners of the universe, ranging from particle physics, to biology, to cosmology. Like the Fibonacci spiral and the golden ratio, the Hopfion pattern unites different scientific fields, and deeper understanding of its structure and influence will help scientists to develop transformative technologies.

Politicians have become more cautious about immunisation prospects. They are right to be.

Recorded May 27, 2020: Watch history unfold on Wednesday, May 27, as NASA and SpaceX launch astronauts Robert Behnken and Douglas Hurley to the International Space Station. This mission marks the first time since the retirement of the space shuttle in 2011 that humans will fly to the space station from U.S. soil.

Tune in starting at 12:15 p.m. EDT as NASA and SpaceX provide joint, live coverage from launch to arrival at the space station. Teams are targeting 4:33 p.m. EDT for the launch of the SpaceX Crew Dragon spacecraft atop a Falcon 9 rocket from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The Crew Dragon is scheduled to dock to the space station at 11:29 a.m. Thursday, May 28.

Advances in artificial intelligence could soon make creating convincing fake audio and video – known as “deepfakes” – relatively easy. Making a person appear to say or do something they did not has the potential to take the war of disinformation to a whole new level. Scroll down for more on deepfakes and what the US government is doing to combat them.

Today we stand at an inflection point. In the months and years ahead, deepfakes threaten to grow from an Internet oddity to a widely destructive political and social force. Society needs to act now to prepare itself.

The first use case to which deepfake technology has been widely applied— as is often the case with new technologies—is pornography. As of September 2019, 96% of deepfake videos online were pornographic, according to the Deeptrace report.

A handful of websites dedicated specifically to deepfake pornography have emerged, collectively garnering hundreds of millions of views over the past two years. Deepfake pornography is almost always non-consensual, involving the artificial synthesis of explicit videos that feature famous celebrities or personal contacts.
