2 . Smartphones, tablets and other digital devices can be addictive. They affect sleep. They draw kids into an alternate universe, often distracting（使分心）them from more productive-and healthier-real-world activities. And they are often linked to anxiety and depression, learning disabilities and obesity（肥胖）. Yet for many teenagers, cellphones and social media are also absolutely necessary tools for planning their social lives, keeping up with schoolwork and staying in touch with out-of-town friends and relatives.
How can parents make the most of the constructive uses of screen-based technology while minimizing its harmful effects？
The key is helping kids use technology as a tool, not a toy, “where there’s some purpose other than the medication of boredom,” says Jim Taylor, a psychologist and author of the book Raising Generation Tech：Preparing Your Children for a Media-fueled World. Taylor, like many other medical and mental health professionals, advises parents to set limits and stick to them. They should restrict the amount of time their kids spend on devices, create tech-free zones-no cellphones in their bedrooms, for example-and tech-free times, such as at the dinner table, in restaurants and on family outings.
Perhaps the best thing you can do is serve as a good role model by exhibiting the same online behavior you expect of your children, says Dr. Elias Aboujaoude, a Stanford University psychiatrist. “If parents are breaking their own rules,” Aboujaoude says, “kids cannot be expected to behave differently.”
Chad Landgraf, 44, of Oklahoma, told me he was worried about how addicted his 12-year-old son and 5-year-old daughter became when they were on their devices. So, hoping to set an example, he switched from e-books to old-fashioned print. “When I had my Kindle or ipad open, they. didn’t know if I was reading or surfing the net,” Landgraf says. “But at least if I have a paper copy of a book, they know I am reading. Modeling seems like the easiest way.”

3 . China has just officially opened its FAST radio telescope to international scientists. Scientists across the world can submit proposals for astronomical observations using the telescope.
FAST is short for Five-hundred-meter Aperture Spherical Telescope (球面射电望远镜) and it is also believed to be the world's largest radio telescope and the most sensitive single-dish radio telescope. The receiving surface area of FAST is 250,000 square meters, about the size of 30 standard football fields. Its construction was completed in September 2016 and it officially began operating in January 2020.
The major scientific task of the telescope is the observation of pulsars (脉冲星) – the rotating neutron stars. The study of pulsars can help to confirm the existence of gravitational radiation and black holes, and help solve many other major questions in physics. Another scientific goal of FAST is to search for outer space civilization.
The telescope is located in a naturally deep and round karst depression in southwest China's Guizhou Province. The first advantage of the selected site is the altitude. The average altitude of Guizhou is about 1,100 meters, which maximizes the effectiveness of the observation equipment. Secondly, the radio telescope needs to have a “big pan” to receive better signal. The huge natural depression could reduce the amount of excavation (挖掘) and difficulty of construction. Moreover, the selected site in Guizhou is far away from cities, and has a small population, which reduces the interference (干扰) caused by wireless devices such as TVs, mobile phones and radios from human activities.
FAST has identified over 300 pulsars. Experts predict that the number could reach 1,000 in five years and that the telescope could locate and identify the first pulsar outside the galaxy. With the opening-up to international scientists, China's FAST is expected to make more contribution to astronomical research in the future.

4 . Each year, about 250 billion to-go cups serve coffee and tea from places like Starbucks and McDonald’s are produced to satisfy the world’s love for hot drinks on the run. These paper-based cups have the inside surface covered with plastic to prevent water from escaping, and keep water from being absorbed into the material. Despite this, that also removes any opportunity for the cups to be biodegradable (可生物降解的).
The materials that created these cups of goodness and convenience are recyclable but only if separated. In addition, the demand for such resources is low, so they are worth next to nothing.
In response to this great challenge, NextGen Consortium, multi-year partnership led by Starbucks and McDonald’s launched their first big initiative (倡议)—NextGen Cup. The first step in NextGen Cup was an open competition where participants presented ideas for sleeves, cups, lids and other parts of the hot-cold paper-based takeaway coffee cup that would make it reusable, recyclable, or biodegradable; to finally be widely used. 12 winners, announced in 2019, shared a prize of $1 million, as well as personalized growth, and support from members of NextGen Consortium.
Later, they launched two pilot programs at independent coffee shops in California. In one case, customers were given “smart” reusable cups made mostly from recyclable plastic. They then could drop their empties into collection containers at key locations, for washing and reuse. These cups were printed with RFID chips or QR codes, through which coffee shops can know where there is the greatest need for collection containers and how many are not using them.
To reduce coffee cup waste, Cup Club is already replacing millions of takeaway cups in the UK, while Recup in Germany, has performed a deposit system that simply adds a small extra fee to any coffee cup which is returned to the buyer after the cup is deposited in any registered collection point.

5 . Plants: we eat them, juice them-and now it seems we can mine them too!
After a successful experiment on the island of Borneo, the botany professor Alan Baker and a group of researchers want to introduce phytomining (harvesting minerals from plants) as a better, partial substitute for traditional mining.
Phytomining, also known as agromining, means collecting metals from live plants. However, this can only be done with a group of plants known as "hyperaccumulators". There are around 700 identified types worldwide, and what makes these hyperaccumulators special is that they naturally attract and absorb minerals through their roots-metals poisonous to other plants-and then store huge, pure concentrations of these minerals in their bodies. The metals can then be extracted from the plants' sap(汁;液), oil, or sometimes even live tissue.
Baker and his colleagues see a lot of potential in phytomining. Not only can it help meet the growing global demand for metals, but is a way of undoing some of that damage to the environment by traditional mining.
One of the biggest problems with traditional mining is that it pollutes the surrounding area. Phytomining can extract metal waste, plus planting the hyperaccumulators would regrow the deforested areas caused by mining operations. Aside from this, if phytomining is able to replace part of traditional mining, then there would be fewer instances of bad mining practices like abandoned mines, which pollute the nearby waters. Also, since phytomining provides metals that are already naturally pure, there is no need to use huge amounts of energy to purify the ore(矿石).
Phytomining has its drawbacks. Harvesting plants on a large scale is expensive today, compared to traditional mining. Besides, plants can be wiped out by diseases or unexpected weather conditions.
However, there are many reasons to consider phytomining. After all, we need to make sure that our planet can keep up and sustainable practices like phytomining give us the hope that our advancement doesn't mean sacrificing Mother Earth.

6 . Windows are a key component in a building's design, but they are also the least energy- efficient part. According to a 2009 report by the United Nations, buildings account for 40 percent of global energy usage, and windows are responsible for half of that energy consumption. If conventional windows are used to better block sunlight passing into a building, they need expensive coatings. Even so, they can not adjust the indoor temperature effectively.
Scientists at the Nanyang Technological University, Singapore (NTU) have developed a smart liquid window panel that can help. By creating a mixture of micro-hydrogel (水凝胶), water, and a stabilizer, they found that it can effectively reduce energy consumption in a variety of climates. Thanks to the hydrogel, the mixture becomes hard-to-see- through when exposed to heat, thus blocking sunlight, and, when cool, it returns to its original clear state. The high heat capacity of water allows a large amount of heat energy to be stored instead of getting transferred through the glass and into the building during the hot daytime when office buildings mainly operate. The heat will then be gradually cooled and released at night when the staff are off duty.
As a proof of concept, the scientists conducted outdoor tests in hot (Singapore, Guangzhou) and cold (Beijing) environments. The Singapore test revealed that the smart liquid window had a lower temperature (50°C) during the hottest time of the day (noon) compared to a normal glass window (84°C), The Beijing tests showed that the room using the smart liquid window consumed 11 percent less energy to maintain the same temperature compared to the room with a normal glass window. They also measured when the highest value of stored heat energy of the day occurred. This "temperature peak" in the normal glass window was 2 pm, and in the smart liquid window was shifted to 3 pm. If this temperature peak shift leads to a shift in the time when a building needs to draw on electrical power to cool or warm the building, it should result in lower energy charges for users. The research team is seeking ways to cut down the cost of producing the smart window and so far, they have found several industry partners to commercialize it.

9 . With the world’s attention on vaccines (疫苗), now feels like a good moment to sing the praises of an often forgotten contribution to their development. Three hundred years ago this month, Lady Mary Wortley Montagu got her daughter inoculated (接种) against smallpox, making her child the first person in the West to be protected in this way. Without Montagu’s willingness to adopt a practice she had learned from other cultures, the introduction of vaccines around 80 years later would never have taken place.
Montagu first witnessed inoculation when she accompanied her husband to Turkey in 1717. Inoculation had started in Asia, probably in China, as early as the 10th century AD. Montagu observed how older women in Turkey took a tiny amount of pus (脓) from a person with smallpox. They then used needles to make cuts on people’s wrists and ankles and added the pus to their bloodstream. This helped people gain immunity from future infection.
Like other visitors to the country, Montagu took steps to ensure that her son was inoculated in Turkey. This worked well, but she knew that trying it in England would be far more challenging. Inoculation performed by unlicensed amateurs would threaten doctors’ professional standing and potentially rob them of valuable income. Churchmen also disagree with the practice, as they saw it as going against nature.
Back in England, Montagu observed the increased severity of smallpox infections. Eventually, in April 1721, she decided to use the Turkish practice to have her daughter inoculated, because she believed that the rewards would outweigh the risks. After a safe time had passed following the inoculation, Montagu allowed doctors to examine her daughter.
Doctors in Britain gradually accepted the practice. About so years later, a pioneering physician found smallpox vaccines to destroy smallpox completely. As early as last century, academics argued that Montagu was no more than an enthusiastic amateur. In truth, she made a vital scientific contribution towards finding the cure for smallpox.
