After you finish your fries, eat the package. When you add your noodles to boiling water, throw the bag into the pot, too. If these instructions sound confusing to you, it’s only because you haven’t yet heard of Notpla, a London-based start-up company that is designing a seaweed-based replacement for single-use plastic packaging.
The approach feels especially great as the world is coming to terms with the effects of decades of plastic production. According to the UN, 330 million tons of plastic waste is produced globally each year, and out of the 9 billion tons of plastic produced since the early 1950s, about 60% has been buried or thrown away as rubbish. Microplastics — tiny pieces that are often the result of larger plastics breaking down — pollute the ocean, the air and our bodies.
“It’s getting more and more clear how big the plastic problem is,” Notpla design director Karlijn Sibbel said. “Producers are ‘using materials that last for thousands of years for products that are only in use for a few minutes’. We firstly looked to seaweed as the solution to the world’s plastic problem because there is plenty of it, it crows quickly, it doesn’t compete with land crops, and it absorbs carbon from the air,” added Sibbel.
“The exciting thing is that the new product named Ooho is a film that can replace most of the flexible packaging that you see around,” Sibbel said. The potential contents could include coffee grounds, toilet paper or the nails used for making furniture. For foods, such as noodles, they have even experimented with adding more taste to the packaging, so that dissolving the bag could add seasoning to the pot.
Last year, Notpla tested 30,000 takeaway boxes in partnership with the online food ordering service Just Eat. The two companies handed out the takeaway boxes at different UK restaurants and plans are being made to offer the boxes around Europe in 2022. As they expand, Notpla’s team hopes seaweed could replace single-use plastic in the supply chain more broadly, but with a large quantity of plastics used around the world, she understands how difficult such a task is, Sibbel said.

【推荐1】You’re on the third lap around the car park, there are no open spaces, and you’re already 15 minutes late for your appointment. Right now you’re wishing you could jump out of the car and let it go find its own spot.
Now there’s an app for that. Virtual Valet lets your iPhone tell your car to park without you in it. “You pull up to the roadside, push a button on your smartphone and the car takes care of everything else,” says Aeron Steinfeld, the lead researcher for the project at Carnegie Mellon University in Pittsburgh, Pennsylvania.
To find its own spot, the system uses a sensor suite similar to those found in many luxury cars. This includes a motion sensor that scans for moving cars and pedestrians, and a forward-facing laser rangefinder normally found in adaptive cruise control to determine the distance of objects in front of the car. Information from these sensors is then fed to an onboard computer to plan the vehicle’s course. The user can watch the whole process from his or her phone.
Better still, it will be affordable. The team has spent the last year moving from high-end imaging and processing equipment to less expensive components. In experiments, the vehicle was able to navigate through a crowded parking structure, find an empty spot, and park all on its own. And the greatest appeal of the Virtual Valet Parking App is that it requires no change to existing parking facilities or infrastructure.
For the moment, the only car equipped for control by Virtual Valet is Carnegie Mellon’s modified (改进的) Jeep Wrangler, which the researchers have named NavLab11. But Steinfeld hopes that major car manufacturers will adopt the technology.
It might be more than technology that holds up the show, however. Self-driving cars have been licensed in only three US states — California, Nevada and Florida — and it’s unclear how this app would agree with self-driving laws. Until these questions are settled, your insurance provider might be unwilling to cover a ding from a parking incident.

【推荐2】Li Bai holds a wine cup in his hand, while Du Fu sits in front of a desk, writing poems on the paper in front of him. It’s not that we have traveled to the past. Modern technology has brought ancient poets “back to life” .
The two great poets, along with other humanoid robots were presented at the World Robot Conference 2023 in late August in Beijing. They looked similar to real human beings.
“The skin is made of medical-grade bionic silicone (仿生硅胶) which is why the skin looks soft and veins can be seen through it,” CGTN explained in a video about Liaoning-based producer EXROBOTS. Goosebumps (鸡皮疙瘩) and palm lines can also be seen on the arms and hands.
Researchers are also trying hard to create other features of humans on robots. A US robotics company Apptronik brought out its humanoid robot called Apollo on Aug 23. Apollo has around 30 muscles. However, humans have around 300 muscles in our bodies. For now, engineers can only simplify the muscles, allowing them to do basic movements like holding objects and walking.
The robot also contains cameras, helping it map out a 360-degree view of its environment. It also has sensors (传感器) in its head to help keep balance when walking on uncertain surfaces.
Nowadays, bionic human-like robots mostly work with humans, as tour guides or by helping visitors at front desks. There are also robots that share the work of nurses, such as handing out medicine. This could be because people are comfortable living and working with machines that look or act like them. “They can strike a chord (引起共鸣) with people,” a US robotics scientist Marc Raibert told New Yorker.
As more humanoid robots come out, safety will be the key, according to the Robot Reportwebsite. When a 70- kilogram robot breaks down and falls, humans nearby may be hurt.

【推荐3】Scientists have designed a new machine—a robot which looks exactly like the famous scientist Albert Einstein. It can recognize and respond to human emotions (情感). The robot is made of special material that allows it to change facial expressions. The material that makes up the robot’s face is so detailed that it looks like real human skin.
The robot’s designers chose Einstein, the Nobel Prize winner, because he was one of the greatest scientists of all time. They also chose Einstein because his face is very well known and he appear ‘loveable’.
Dr. Hanson, who designed the robot, explained that it was important to develop machines that know what human beings are feeling.
The robot uses computer software that helps it to understand hundreds of human expressions such as sadness, anger, fear and happiness. It can also recognize a person’s age, and whether they are male or female. Mr. Movellan, who designed the software, said that in the future the robot could be in museums to help people from different cultures to understand one another.

【推荐1】Can everything be recycled? No, not all things can be recycled. But you might be surprised to learn how many things can be recycled. You may already know about plastic bottles. Did you know you can also recycle glass?
Glass can be recycled to make all sorts of things. Recycling glass really helps the planet. Making new products from recycled glass causes less air and water pollution. It also uses less energy than making new glass.
When glass arrives at a recycling plant, people and machines sort it by color. Similar colors of glass must be recycled together. That way, recycled products are as pure as possible. This makes them stronger and less likely to break. Once the glass is sorted, it's washed. That's when the breaking begins. That's right! To be recycled, glass has to be broken to make a material called cullet(碎玻璃).
Glass manufacturers love cullet. It's cheaper than the raw materials they'd need to make new glass. It also melts at a lower temperature. That means they save energy during the production process. Glass manufacturers mix cullet with other materials like sand and soda ash. Then they heat it to over 2,600℉. This makes liquid glass, which can then be poured into a mold (模具). There, it cools and forms a finished glass product.
Most recycled glass is used to make new glass containers, such as jars and bottles. However, recycled glass can also find its way into all sorts of other products including a variety of construction products.
Do you recycle at home or school? What glass products should you be sure to recycle when you’ re done with them? With everyone doing their part, recycling glass can make a huge difference to the planet!

【推荐2】The blanket of pollution resulting from carbon dioxide emissions from fossil fuels is already warming the planet and causing more extreme weather disasters. One way to keep climate change from getting worse is to take some of those historic emissions out of the atmosphere. More than 200 scientists have signed onto a letter pushing for “responsible” research into ways to trap planet-heating carbon dioxide in the world’s oceans.
Oceans already do that for us, absorbing and holding around 50 times more carbon than the atmosphere. What if humans could supercharge that ability? That’s what scientists want to better understand, along with any side effects that might come with messing with the chemistry of our oceans.Startups are already developing new technologies to sequester(隔绝)more CO2 in the sea. But there’s still a lot we don’t know about what impact that might have or what strategies might be most successful, the letter says.
These are all pretty early efforts, and hacking the high seas is no replacement for preventing greenhouse gas emissions from accumulating in the atmosphere by getting rid of fossil fuels. Some environmental advocates are also worried about new CO2-filtering technologies harming marine life.
The letter today calls for controlled field trials to evaluate carbon removal strategies, along with a third-party review of the results. There also need to be safety measures in place to address any “unintended or harmful consequences” and inclusive policies to engage different stakeholders(利益相关者).Some big names in climate and environmental sciences have signed on.
“I have seen these massive declines in ocean health...Doing nothing is unethical(不道德的) essentially,” says Débora, Ecology, Evolution, and Marine Biology department chair at the University of California, Santa Barbara, who signed the letter released today. When it comes to studying new ways to use oceans to tackle climate change, she says,“ We need to at least figure out the risks and the benefits, see whether we can help resolve the problem we have created.”

【推荐3】1970 was World Conservation Year. The United Nations wanted every one to know that the world is in danger. They hoped the governments would act quickly in order to “conserve” nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can’t live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future? Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through something called “No one’s going to change our world”, which was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

Protected areas have mixed success in protecting wildlife, according to the largest study on the effects of reserves(保护区).
A team led by researchers from the U.K. examined water bird data from 1,506 protected areas and analyzed more than 27,000 bird populations across the world. The authors write that their study, published in Nature, is the first robust(强有力的), global assessment of protected areas’ influence on bird populations. The scientists found that protected areas with management of water birds and their habitats were more likely to benefit those populations.
“Our study shows that, while many protected areas are working well, many others are failing to have positive effect,” lead author Hannah Wauchope of the University of Exeter says in a statement. The study compared water bird populations before and after the establishment of protected areas and also compared trends of similar populations within and outside of protected areas. Water birds respond quickly to changes in site quality, making them a good group to look at when studying the impact of protected areas.
“In the majority of places we looked at, wildlife populations were still stable or were increasing, but they weren’t doing any better than in unprotected areas,” Wauchope says. “That’s disappointing, but not surprising. There seems to be this disconnect between people talking about how much land is protected and whether those areas are actually doing anything positive.”
This research comes ahead of a United Nations meeting in China to discuss biodiversity goals for the next decade. Several countries have already devoted to protecting 30 percent of the planet by 2030, yet researchers say protection alone does not necessarily ensure positive outcomes for species.
“We are not saying protected areas don’t work,” Wauchope concludes in the statement.” The key point is that their effects vary hugely, and the biggest thing this depends on is whether they are managed with species in mind—we can’t just expect protected areas to work without effective management.”

【推荐2】Some of the greatest moments in human history were fueled by emotional intelligence. When Martin Luther King Jr. presented his dream, he chose language that would stir the hearts of his audience. Delivering this electrifying (展性的) message required emotional intelligence — the ability to recognize, understand, and manage emotions.
Emotional intelligence has been highly recommended by leaders, policymakers, and educators as the solution to a wide range of social problems. If we can teach our children to manage emotions, the argument goes, we’ll have less bullying and more cooperation. If we can cultivate emotional intelligence among leaders and doctors, we’ll have more caring workplaces and more compassionate healthcare.
Emotional intelligence is important, but the uncontrolled enthusiasm has obscured (掩盖) a dark side. New evidence shows that when people sharpen their emotional skills, they become better at manipulating (把持) others. When you`re good at controlling your own emotions, you can hide your true feelings. When you know what others are feeling, you can motivate them to act against their own best interests.
Social scientists have begun to document this dark side of emotional intelligence. In a research led by University of professor Jochen Menges, when a leader gave an inspiring speech filled with emotion, the audience was Jess likely to scrutinize (细察) the message and remembered of the content. Ironically (讽刺的是) audience members were so moved by the speech that they claimed to recall more of it.
The authors call this the awestruck effect, but it might just as easily be described as the dumbstruck effect. One observer reflected that Hitler’s persuasive impact came from his ability to strategically express emotions — he would “ear open his heart — and these emotions affected his followers to the point that they would stop thinking critically and just emote.”
Leaders who master emotions can rob us of our capacities to reason. If their values are out of step with our own, the results can be destructive. New evidence suggests that when people have self-serving motives (动机), emotional intelligence becomes a weapon for manipulating others. In a study led by the University of Toronto psychologist Stephane Cote, university employees filled out a survey about their Machiavellian (不择手段的) tendencies, and took a test measuring their knowledge about effective strategies for managing emotions. Then, Cote’s team assessed how often the employees deliberately undermined (逐渐削弱) their colleagues. The employees involved in the most harmful behaviors were Machiavellians with high emotional intelligence. They used their emotional skills to lower the dignity of their peers for personal gain.
Shining a light on this dark side of emotional intelligence is one mission of a research team led by University College London professor Martin Kilduff. According to these experts, emotional intelligence helps people disguise (伪装) one set of emotions while expressing another for personal Professor Kiiduit’s team writes, “The strategic disguise of one’s own emotions and the manipulation of others’ emotions for strategic ends are behaviors evident not only on Shakespeare’s stage but also in the offices and corridors where power and influence are traded.”
Of course, people aren’t always using emotional intelligence for nefarious ends. More often than not, emotional skills are simply instrumental tools for goal accomplishment. A research team discovered that founder Anita Roddick used emotional intelligence to inspire her employees fundraise for charity. As Roddick explained, “Whenever we wanted to persuade our staff to support a particular project, we always tried to break their hearts.”
There is growing recognition that emotional intelligence-like any skill-can be used for good or evil. So if we’re going to teach emotional intelligence in schools and develop it at work, we need to consider the values that go along with it and here it’s actually useful.
