North Korea reportedly threatens ‘new round of the Korean War’ to end US

Posted by in categories: existential risks, military

North Korea’s embassy in Moscow has threatened to use its nation’s nuclear weapons against the United States in what they claim would be “a particularly sensational event,” a Russian state-owned news agency reports.

The reporting comes from the TASS news agency, a state-owned wire service known largely as a propaganda outlet for the Kremlin, which claims the embassy sent them the threat in the form of a statement over the weekend.

The agency quotes the embassy as stating, “This year, the U.S. military has been carrying out various kinds of military maneuvers in South Korea and its vicinity with the purpose of striking North Korea quickly.”

Nuclear waste shipment leaves Germany for Russia

Posted by in category: nuclear energy

The waste will reportedly be moved by sea and rail to a plant in the Urals.

Urenco told the BBC its uranium would be further enriched in Russia and the process met environmental standards.

But environmental activists have long been concerned that Russia may become a “dumping ground” for radioactive waste from power plants.

Solar-powered poultry farm floated for Rotterdam harbor

Posted by in categories: food, sustainability

We’ve reported on several eye-catching floating architecture projects lately, including a “parkipelago” and a greenery-covered office. This solar-powered urban poultry farm is the most off-the-wall idea of the bunch though and, assuming it goes ahead as planned, will host roughly 7,000 egg-laying hens, as well as an area for growing food, in a harbor in Rotterdam, the Netherlands.

The building is officially named Floating Farm Poultry and was designed by Goldsmith for a company named Floating Farm Holding BV.

It will be based on a floating platform with three pontoons and will measure 3,500 sq m (roughly 37,670 sq ft), spread over three floors. Its interior layout will consist of a lower level used for farming vegetables, herbs and cresses under LED lighting, while upstairs will be a production factory floor for processing and packaging. The uppermost level is conceived as the poultry area and will contain the egg-laying hens.

NASA’s Ingenuity helicopter is traveling to Mars attached to the belly of the Perseverance rover and must safely detach to begin the first attempt at powered flight on another planet. Tests done at NASA’s Jet Propulsion Laboratory and Lockheed Martin Space show the sequence of events that will bring the helicopter down to the Martian surface.

We must become a multi-planet species

Posted by in categories: Elon Musk, existential risks, genetics, space travel, sustainability

Former astronaut Jeffrey Hoffman: For the long-term survival of our species, we have to become a multi-planet being.


With our rising planet’s population competing for space and resources, some people are convinced we need to look beyond Earth to help ensure humanity’s survival. As Elon Musk, the entrepreneur behind space tourism company SpaceX told Aeon’s Ross Andersen: “I think there is a strong argument for making life multi-planetary in order to safeguard the existence of humanity in the event that something catastrophic were to happen.”

At Long Last: An Answer to the Mystery Surrounding Matter and Antimatter

Posted by in category: physics

An element that could hold the key to the long-standing mystery around why there is much more matter than antimatter in our universe has been discovered in Physics research involving the University of Strathclyde.

The study has discovered that an isotope of the element thorium possesses the most pear-shaped nucleus yet to be discovered.

Nuclei similar to thorium-228 may now be able to be used to perform new tests to try find the answer to the mystery surrounding matter and antimatter.

A structural light switch for magnetism

Posted by in categories: computing, physics

Magnetic materials have been a mainstay in computing technology due to their ability to permanently store information in their magnetic state. Current technologies are based on ferromagnets, whose states can be flipped readily by magnetic fields. Faster, denser, and more robust next-generation devices would be made possible by using a different class of materials, known as antiferromagnets. Their magnetic state, however, is notoriously difficult to control.

Now, a research team from the MPSD and the University of Oxford has managed to drive a prototypical antiferromagnet into a new magnetic state using terahertz frequency . Their groundbreaking method produced an effect orders of magnitude larger than previously achieved, and on ultrafast time scales. The team’s work has just been published in Nature Physics.

The strength and direction of a magnet’s ‘north pole’ is denoted by its so-called magnetization. In ferromagnets, this easily reversible magnetization can represent a ‘bit’ of information, which has made them the materials of choice for magnet-based technologies. But ferromagnets are slow to operate and react to stray magnetic fields, which means they are prone to errors and cannot be packed very closely together.

An experiment suggested by a Ph.D. student may rewrite chemistry textbooks

Posted by in categories: chemistry, innovation

Yan McMullen had never heard of the USC Dornsife College of Letters, Arts and Sciences when he started casting about for a graduate chemistry program. But on the recommendation of one of his professors, he sent an email to the College’s Professor of Chemistry Stephen Bradforth proposing an experiment to tease out what makes a metal really a metal.

The proposal would not only turn into his Ph.D. thesis but a major scientific breakthrough.
