5 . Two vaccines（疫苗）developed by a Maryland company are showing promise in the fight against malaria（疟疾）. One vaccine was 100 percent effective in preventing the deadly disease malaria.

Malaria is a disease caused by parasites（寄生虫）and carried by mosquitoes. Parasites are organisms that live on or in an organism of another species and feed off it or get protection from it. Mosquitoes spread the disease to people by biting on their skin. The World Health Organization says there are 214 million cases of malaria each year. And the deadly disease kills over 400,000 people a year worldwide. People who have malaria often have a fever, chills, and flu-like illness. Serious complications happen, including death, when the disease is left untreated.

The new vaccines work by preparing the immune system to fight the disease. Researchers do this by introducing live, but weakened, young parasites called sporozoites. They are injected into the body by infected mosquitoes. Both vaccines target Plasmodium Falciparum（恶性疟原虫），which is the most common and deadly form of the disease.

One successful trail was carried out in Germany. Different amounts of the vaccine were injected into 27 healthy people who volunteered for the study. Another group of 15 was given a placebo, which is a substance given to a patient like a drug, but t has no physical effect on the person. Eight to 10 weeks after the last vaccine amount, both groups were then exposed to the parasites that carried the malaria.

Stephen Hoffman is chief executive and scientific officer of Sanaria. He says the researchers were surprised by the results from nine of the people who received the highest vaccine amount. “We got 100% protection against malaria at ten weeks after the last amount of the vaccine. That is really beginning to look like something quite extraordinary and that's never been done before.”

6 . Thinking about holidaying alone, but a bit concerned about the pitfalls? You needn’t worry if you consider these tips first.

Safety

Unless you positively invite danger—i.e. hanging around a remote park at 4 a.m. with headphones on—travelling alone isn’t actually that risky. The biggest danger is being taken for a ride. Literally, in the case of taxi drivers: always ask for an estimated fare before setting off. Otherwise, try to never look like a tourist. Ensure that someone else knows your journey and commit to regular contact with them.

Plan

Being alone means you can’t use your friends’ phones when yours runs out of juice, or rely on them should you lose your wallet. Put emergency systems in place: write down key numbers (friends, hotels, embassies, emergency services), have change for phone boxes and always keep some back-up money in your bag.

Making friends

This is another common and very valid worry when travelling alone: what if no one likes me? Acquiring new companions is always easier than feared, but still a scary subject. It helps to look approachable—smile at people, have open body language and lose the sunglasses. Read something interesting to start a conversation, or ask strangers a question.

More hands-on methods include visiting expatriate bars, joining tours or using apps designed to help people make friends, such as Meetup.

7 . The River Thames has some of the highest recorded levels of microplastics for any river in the world.

Scientists have estimated that 94,000 microplastics per second flow down the river in places. The quantity is larger than that measured in other European rivers, such as the Danube and Rhine. Tiny bits of plastic have been found inside the bodies of crabs living in the Thames.

Researchers at Royal Holloway, University of London, are calling for stricter regulations on the labelling and disposal of plastic products. They warn that careless disposal of plastic gloves and masks during the coronavirus pandemic might make the problem of plastic pollution worse.

“Taken together, these studies show how many different types of plastic, from microplastics in the water through to larger items of debris physically altering the foreshore, can potentially affect a wide range of organisms in the River Thames,” said Prof Dave Morritt from Royal Holloway, “The increased use of single- use plastic items, and the inappropriate disposal of such items, including masks and gloves, along with plastic- containing cleaning products, during the current COVID-19 pandemic, may well make this problem even worse.”

Many forms of microplastics were found in the Thames, including glitter, microbeads from cosmetics and plastic debris from larger items. Most of the microplastics came from the break-down of large plastics, with food packaging thought to be a significant source. “Flushable” wet wipes were found in high abundance on the shoreline forming “wet wipe reefs”.

Study researcher, Katherine McCoy, said, “Our study shows that stricter regulations are needed for the labelling and disposal of these products. There is great range to further research the impacts of microplastics and indeed microfibres on Thames organisms.”

8 . Marco Springmann and his colleagues, at the Oxford Martin School's Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan, the greenhouse gas emissions declines would be around 70%.

In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars——but it is cars, not steaks, that regularly come up in discussions about global warming.

Food, especially livestock, also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.

However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. "I'm sitting here in Scotland where the Highlands' environment is very man-made and based largely on grazing by sheep," says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. "If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity. "

Plus, meat is an important part of history , tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.

And nowadays, moderation in meal-eating's frequency and portion size is key to solving these conflicts. "Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions," says Springmann, "like putting a higher price lag on meat and making fresh fruits and vegetables cheaper. "

In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to implement those changes.
