Weightless environment kills 80% of cancer cells

Australian researchers found that more than 80% of cancer cells have died after one day of weight loss. The results of this test confirm the similar findings of German researchers in 2017. The researchers plan to send cancer cells to the International Space Station for further research.

“We can’t develop a panacea for cancer, because everyone has different types of cancer and different body reactions,” said Joshua Zhou, a researcher at the University of Technology, Sydney. “But I want to know if there are some commonalities between these cancers. “They placed different cancer cells from four body parts – breast, ovary, lung and nose under microgravity conditions and found that these cancer cells had a mortality rate of 80% to 90% within 24 hours.”

Zhou Zheng plans to send cancer cells to the International Space Station in 2020 with his assistants. “We want to see if it is microgravity or something else in space, such as solar radiation, which has an effect on cancer cells.”

Is the current popular vegetarianism lowering the IQ of the next generation? According to the British “Daily Mail” reported on August 30, public health nutritionist Dr. Derby Hill published an article in the British medical journal Nutrition, Prevention and Health, saying that long-term vegetarian diet may cause choline deficiency, and gallbladder Alkali is a nutrient necessary for the development and functioning of the brain, especially in women of childbearing age. If the intake of choline is insufficient, it is likely to cause the next generation of IQ to be low. Choline can be obtained from meat, liver and eggs. If it is not adequately ingested, it needs additional supplementation.

Studies have shown that the current British intake of meat is less than ever, with 21% of British households reducing their intake of meat in the past two years. Currently, 10% of households in the UK have intermittent vegetarian diets. 5% of families are vegans. More and more evidence shows the importance of choline, but this nutrient has long been ignored by vegetarians.

Brazilian President Bossonaro is dissatisfied with the proposal of French President Mark Long to put the Amazon rainforest on fire on the agenda of the G-7 summit. He said that in view of Mark Long’s remarks on the Amazon rainforest fire, he will stop using the French Bickey ballpoint pen.

According to Agence France-Presse reported on August 31, Bosonaro said on August 30: “I will use Compac⁃torpen (a Brazilian brand) instead of the French Bickey ballpoint pen.” When asked about the president’s remarks Whether it was just a joke, the Brazilian president’s office declined to comment. A spokesperson for the Bick company said that most of the Bik ballpoint pens sold in Brazil are produced in the factory in Manaus, the capital of the Brazilian state of Brazil.

According to reports, because the Bic is cheaper and very common in Brazil, Bossonaro often uses his signature documents to show his low-key, economical style. Some foreign netizens commented on the Mercopress news website in South America. Bosonaro is getting more and more “Trumps”. Like a 5-year-old child, he should throw away his favorite Montblanc pen. After all, these pens are Named after Mont Blanc in France

In addition to ordinary ceramics, British fashion restaurants are digging into other materials to hold dishes – they are eyeing slate tiles, which exposes construction workers to the shortage of materials when building roofs.

According to the British “Daily Mail” reported on the 1st, the use of slate tiles to display dishes has led to a shortage of such building materials, as quarries have turned to produce more profitable slate tableware products.

Roof construction expert Philip Brooke said that the demand for tableware is not the only reason for the shortage of slate tiles, but it is one of the important reasons: because the construction company’s bid is not as high as the restaurant, the difficulty of obtaining such building materials is increasing. “Price is the main factor. Compared with tableware manufacturers, the construction industry is putting more pressure on suppliers in terms of price.” In addition, he said that the source countries have closed many quarries due to environmental reasons, which has further led to supply. insufficient.

a research report published by the famous academic journal Science recently stated that homosexuality is not determined by a single gene, but by the joint influence of congenital genes and acquired environment.

Scientists from Finland, the United States and other countries conducted detailed investigations on DNA samples and living habits of nearly 500,000 people in the United States and the United States, and conducted genome-wide association analysis. The study found that sexual orientation does have genetic components, but overall it is not as large as some studies think. For sexual orientation, there is no single homosexual gene in the world, but a certain influence of various genetic interactions.

The researchers said that five genetic markers are “significantly” associated with homosexual behavior, but one’s sexual orientation is still difficult to predict. Researchers say this suggests that non-genetic factors such as the environment, parenting style, personality and educational approach are more likely to significantly affect a person’s sexual orientation, just like personality, behavior, and physical characteristics.

More and more French people are fascinated by the use of magnets to “suck gold” in the river, but the authorities warned that the act is not only environmentally unimagined, but can also lead to personal danger. According to a report by France’s 24 TV station on August 31, bicycles, kitchen utensils, metal fences… are all “babies” that history enthusiasts and environmentalists have used to salvage rivers and lakes with powerful magnets. This has become a popular pastime for many French people and is seen as a good way to hunt for treasure and remove pollution.

Owen, who has been “sucking gold” on the Oise River in a small town near Paris, said that many military fans “sucked” metal medals and relics of war in the water and also picked up a lot of waste products and cleaned the river.

However, people’s casual salvage can also be dangerous. In some cities that were traumatized by World War I, some people used to salvage rifles and grenades in the river. In May of this year, an accident involving a “golden smuggler” wounded by a mustard gas bomb was found in Dunkirk. In addition, experts say that heavy magnets tend to scratch the bottom of the river, possibly destroying fish eggs and destroying underwater ecosystems. At present, the French government has asked people to obtain relevant permits to start salvage.
