Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.

It is true that self-driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver, nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation(航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

Therefore, comparisons between humans and auto-mated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.

European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future. Researchers from the European Space Agency, or ESA, carried out the experiments at a laboratory in the Netherlands.

The team says ESA's experimental "plant" was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith, a top layer of dirt and rock pieces that sit on the surface of the moon. Samples of regolith returned from the moon have confirmed that the material contains about 45 percent oxygen by weight. However, the oxygen is chemically locked in the form of minerals or glass, so it is not easily available for use. Having real samples of regolith from the moon made it possible for the researchers to create the simulated moon dust material used during testing.

The oxygen extraction(提取) process is carried out using a method called molten salt electrolysis(熔盐电解). This includes first placing the regolith in a metal container. Calcium chloride salt is added to the mixture, which is then heated to 950 degrees Celsius. At this temperature, the regolith remains solid. Next, an electrical current is passed through the material. The researchers say it is this step that results in oxygen being extracted from the regolith. The study reported that up to 96 percent of oxygen in the simulated moon dust was extracted during the experiments.

ESA's long-term goal is to design an oxygen-producing "pilot plant" to operate full-time on the moon. The first technology demonstration of the system is expected to take place in the middle 2020s. Beth Lomax, a lead researcher on the project, said, "Being able to acquire oxygen from resources found on the moon would obviously be hugely useful for future lunar settlers, both for breathing and the local production of rocket fuel. "The researchers reported that "as a bonus", the process also results in the production of usable metallic materials.

ESA and the US space agency NASA are both working on plans to return human beings to the moon. NASA has set a goal for 2024 with the aim to keep humans on the moon for long periods.

A new study published this week in the journal Nature Communications has concluded that a 100 percent change to organic(有机的) food production in England and Wales would actually lead to a great increase in greenhouse(温室) gas emissions(排放). In turn, this would contribute to further climate change.

Although organic farming directly pours out fewer emissions than conventional farming—around 20 percent lower for crops and 4 percent for farm animals—it produces notably less food. As to this study's findings, total organic agriculture in England and Wales would produce 40 percent less food. With less food in the market, the countries would need to increase food imports, which would produce more global greenhouse gas emissions.

Organic farming also increases the amount of absorbing carbon, a process where carbon dioxide (CO₂) is "absorbed" out of the atmosphere and captured by plants and stored in the soil. However, even a total change to organic farming would only be equal to a tiny part of the higher emissions from overseas land use.

"We predict a drop in total food production of 40 percent under a fully organic farming process, compared to conventional farming, if we keep to the same national diet, " Dr Adrian Williams, lead author and reader in Agri-Environmental Systems at Cranfield University, said in a statement. "This results from lower crop quantity, because output is limited by a lower supply of nitrogen, which is mainly from other crops or solid waste from cattle on the grassland. "

Nevertheless, it is important to note that organic farming still holds some useful benefits for the environment, such as reducing exposure to chemicals and improving the varieties of creatures. In conclusion, the study suggests that organic farming will continue to play a key role in resolving the world's environmental problems. However, it's just one part of a much wider solution.

Here's how it 4. Volunteers help clean up 300 miles of shoreline. Then, 5 only plastic from the beach cleanup, Angela and many other volunteers create sculptures of sea 6. She explains, "I mean to create sculptures that make people take a look and 7, 'How can there be this much waste on the beach？' 8, these sculptures will make people consider what they have 9 in their daily life and realize how so much plastic ends up in the oceans."

How to be strong and healthy

It is obvious that some students are neither in good health nor full of energy.

A knock at the front door announced a visitor. Phil Radcliffe opened the door, looked down, and found a small boy of about 10, head down and face hidden, nose sniffling(抽鼻子), obviously in some unhappiness.

Phil and his wife Molly lived in this neighbourhood for almost three decades. The families here all knew and trusted one another. Youngsters bounced from home to home looking for friends and entertainment. In the school holidays, Molly and Phil had been known to take children at a time to the local cinema to give some of the parents a break.

Having taken him to the living room and had him seated, Phil asked the boy, "Philip, what's happened?"

The boy seemed genuinely upset by the inquiry. "Sorry, Mr. Radcliffe, " he sobbed, "My dad's just left home. He is not going to live with us any more. Mum's crying. It's made me cry. I don't think I'm going to see him again. "

Phil sat down next to him and put a comforting arm around his shoulders, trying to reassure the youngster, "I'm sure that you'll see your father again very soon Philip. You're a lovely boy and he'll want to see you a lot. And your teachers will understand if sometimes you're a bit sad. "

The boy wiped away his tears with the back of a hand.

"Let me get something for us," Phil suggested. He went into the kitchen, and then returned with an orange juice for the boy, a coffee for himself and a selection of biscuits for them. However upset he might have been, young Philip was obviously happy with the drink and concentrated on the chocolate samples among the biscuits.

Once the boy seemed more settled, Phil proposed, "Perhaps you should call your mum and tell her where you are, so that she doesn't worry. "

"It's OK, Mr. Radcliffe" he insisted. "I'll go home in a few minutes. But I like talking to you. "

"You can stay as long as you want, Philip. I just don't want your mother to think that she's lost you. "
