Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars.

In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany. PPPL founder Lyman Spitzer Jr. invented the stellarator in the early 1950s.

Most stellarators use a set of complex twisted coils that spiral like stripes on a candy cane to produce magnetic fields that shape and control the plasma that fuels fusion reactions. Refrigerator-like permanent magnets could produce the hard part of these essential fields, the researchers say, allowing simple, non-twisted coils to produce the remaining part in place of the complex coils.

Population Research Institute President Steven W. Mosher wrote at the New York Post on Saturday that China’s coronavirus epidemic could have been unleashed by researchers who sold laboratory animals to the notorious “wet markets” of Wuhan for extra cash.

Mosher is not the first skeptic of Beijing’s official coronavirus narrative to note the presence of an advanced microbiology lab near Wuhan, the city where the epidemic originated. Since the early days of the crisis, theories have suggested everything from the lab accidentally releasing the virus to speculation that the virus might have been deliberately designed as a biological weapon.

His theory cited as evidence the release of new guidelines from the Chinese Ministry of Science and Technology calling for “strengthening biosecurity management in microbiology labs that handle advanced viruses like the novel coronavirus.”

The House is preparing to vote on Thursday on a coronavirus-relief bill that would provide Americans with paid sick leave, food assistance, free coronavirus testing, and more substantial unemployment benefits.

But Ocasio-Cortez pushed for a more sweeping response, including expanding Medicare or Medicaid to cover all Americans, a freeze on evictions, a universal basic income, ending work requirements for food-assistance programs, criminal-justice reform, and freezing student-debt collection.

“This is not the time for half measures,” she tweeted on Thursday. “We need to take dramatic action now to stave off the worst public health & economic affects. That includes making moves on paid leave, debt relief, waiving work req’s, guaranteeing healthcare, UBI, detention relief (pretrial, elderly, imm).”

“In the case of the Industrial Revolution, people’s lives didn’t improve for seven decades,” Frey says. “That’s two generations. I think we need to be very concerned about some of these short-term effects on people.”

Frey says for seven decades wages were stagnant, food consumption decreased and “people’s living standards deteriorated.” The economy was doing quite well, but most of the workers weren’t seeing the benefits of that economy.

“Because people’s living standards deteriorated, people rioted against mechanized factories. The Luddites are often portrayed as these irrational enemies of progress, and to some extent, that’s right if you take a very long term view,””


The case against the flawed argument that automation won’t be so bad.

In a new publication in Nature Plants, assistant professor of Plant Science at the University of Maryland Yiping Qi has established a new CRISPR genome engineering system as viable in plants for the first time: CRISPR-Cas12b. CRISPR is often thought of as molecular scissors used for precision breeding to cut DNA so that a certain trait can be removed, replaced, or edited. Most people who know CRISPR are likely thinking of CRISPR-Cas9, the system that started it all. But Qi and his lab are constantly exploring new CRISPR tools that are more effective, efficient, and sophisticated for a variety of applications in crops that can help curb diseases, pests, and the effects of a changing climate. With CRISPR-Cas12b, Qi is presenting a system in plants that is versatile, customizable, and ultimately provides effective gene editing, activation, and repression all in one system.

“This is the first demonstration of this new CRISPR-Cas12b system for plant genome engineering, and we are excited to be able to fill in gaps and improve systems like this through new technology,” says Qi. “We wanted to develop a full package of tools for this system to show how useful it can be, so we focused not only on editing, but on developing gene repression and activation methods.”

It is this complete suite of methods that has ultimately been missing in other CRISPR systems in . The two major systems available before this paper in plants were CRISPR-Cas9 and CRISPR-Cas12a. CRISPR-Cas9 is popular for its simplicity and for recognizing very short DNA sequences to make its cuts in the genome, whereas CRISPR-Cas12a recognizes a different DNA targeting sequence and allows for larger staggered cuts in the DNA with additional complexity to customize the system. CRISPR-Cas12b is more similar to CRISPR-Cas12a as the names suggest, but there was never a strong ability to provide gene activation in plants with this system. CRISPR-Cas12b provides greater efficiency for gene activation and the potential for broader targeting sites for , making it useful in cases where genetic expression of a trait needs to be turned on/up (activation) or off/down (repression).
