Summary: Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme densities if its interaction with the reactor walls is carefully controlled. This finding removes a major obstacle that has slowed progress toward fusion ignition. The advance could help future fusion reactors produce more power

Scientists working with China’s fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have successfully reached a long-theorized “density-free regime” in fusion plasma experiments. In this state, the plasma remains stable even when its density rises far beyond traditional limits. The results, published in Science Advances on January 1, shed new light on how one of fusion energy’s most stubborn physical barriers might finally be overcome on the road to ignition.

When literature became propaganda

Six books you didn’t know were propaganda

Governments influence a surprising amount of literature. Some of it pretty good

“ALL ART is propaganda”, wrote George Orwell in 1940, “but not all propaganda is art.” Few people would argue with the second part of that aphorism. There is nothing artistic about the dreadful ramblings of “Mein Kampf”. But the first seems true only if you are using a broad definition of propaganda. These days great works of art rarely set out to serve the purposes of a government. They may promote causes, but that is not normally why people esteem them. The books on this list, however, partially vindicate the first part of Orwell’s assertion. Governments or ideological groups either encouraged their authors to write them or promoted their writings for political ends. During the cold war Western intelligence agencies subsidised authors, sometimes very good ones. The CIA set up literary magazines in France, Japan and Africa. One purpose was to counter censorship by autocrats. Another was to make global culture friendlier to Western aims. British intelligence services commissioned works of fiction that supported empire. Some writers consciously offered their pens to the state; others did not realise that governments or groups would promote their work. Here are six books, all by authors of merit, that are works of propaganda in one way or another.

Vietnam artist in race to ensure ‘heroic mothers’ not forgotten

CAO LANH CITY, Vietnam, March 29 (Reuters) – On her trusty motorcycle, Vietnamese artist Dang Ai Viet travels around the Southeast Asian country in a quest to ensure that the thousands of women who suffered the loss of two or more loved ones during the Vietnam War are not forgotten.

The 75-year-old has painted the portraits of 2,765 of the women, who are part of a group known in Vietnam as “heroic mothers”, in recognition of their sacrifice during the war that ended in 1975.
