What do you do when your CEO confesses that he's cracking under the stress of his job?

China has ordered the world's top pork producer, WH Group Ltd , to shut a major slaughterhouse as authorities race to stop the spread of deadly African swine fever (ASF) after a second outbreak in the planet's biggest hog herd in two weeks. The discovery of infected pigs in Zhengzhou city, in central Henan province, about 1,000 km (625 miles) from the first case ever reported in China, pushed pig prices lower on Friday and stirred animal health experts' fears of fresh outbreaks - as well as food safety concerns among the public.

The imam of a mosque attended by the Manchester bomber praised “jihad for the sake of Allah” at a sermon months before the atrocity, it has emerged. Didsbury Mosque insisted there was no call for “military” jihad but rather a struggle for the oppressed, and denied any links between its teachings and Salman Abedi’s radicalisation. Police are reviewing a recording obtained by the BBC of a sermon given by imam Mustafa Graf in December 2016, days before Abedi bought a ticket for the Ariana Grande concert where he would detonate a suicide bomb that killed 22 victims.

South Korea's Jin Air escaped the worst of regulatory wrath on Friday when it was allowed to keep its business licence in the wake of public outrage over the behaviour of members of its founding family. The country's No.2 budget carrier's licence was put under review after it was found that family member Emily Cho - in the spotlight after reports of an angry tantrum earlier this year - held U.S. citizenship while serving as board director in violation of South Korean law. Although Jin Air kept its licence, it will be restricted from registering new aircraft and routes for a "certain period of time", the transport ministry said in a decision that pared initial sky-high gains for its stock.

Two women charged with murdering the estranged half-brother of North Korean leader Kim Jong Un must answer for their role in a well-planned conspiracy, a Malaysian judge said on Thursday, but added that the evidence did not prove a political assassination. Indonesian Siti Aisyah and Doan Thi Huong, a Vietnamese, face the death penalty on charges of murdering Kim Jong Nam by smearing his face with VX, a nerve agent banned by the United Nations, at a Kuala Lumpur airport on Feb. 13 last year. The murder was a "well-planned conspiracy between the women and the four North Koreans at large", trial judge Azmi Ariffin said in a ruling that took more than two hours to read.

With all the incredible medical and technological advancements coming out of the scientific community these days you might not think that researchers would be spending time studying spaghetti, but you'd be wrong. In a new paper published in Proceedings of the National Academy of Sciences, MIT scientists explain how to correctly break strands of the stringy pasta in half. If you've ever made spaghetti you'll be very familiar with this particular problem: Dry spaghetti strands don't fit perfectly in most stovetop pots. You can either drop them in at full length and let them hang over the edge as the bottom half goes soft to snap them in half, in which case you'll end up with a bunch of smaller pasta chunks and a metric ton of tiny spaghetti fragments that aren't good for much of anything. Not wanting to pass up the opportunity to solve a problem, a duo of MIT researchers decided to test the mechanics that leads to dry spaghetti strands busting up into a million tiny chunks rather than two uniform halves. What they discovered is an issue that plagues many long, thin objects, and they've even come up with a solution. "A well-known problem with direct implications for the fracture behavior of elongated brittle objects, such as vaulting poles or long fibers, goes back to the famous physicist Richard Feynman who observed that dry spaghetti almost always breaks into three or more pieces when exposed to large bending stresses," the researchers write. The fix? Add a twist to the pasta as you bend it. A twisting motion of approximately 270 degrees seems to be the sweet spot. This helps to control the stress on the object and results in a much cleaner split. "Our experimental and theoretical results demonstrate that twisting enables remarkable fracture control by using the different propagation speeds of twist and bending waves," the team explains. This all might sound a little silly, but the research has implications far beyond your dinner plate. The neat thing about experiments like this is that the knowledge gained can be used for other applications, and the results of the experiments can now be used as a foundation for better understanding the fracturing habits of other, slightly more important objects than spaghetti.
