All over the globe and in some of the world's most prestigious art galleries and museums there is always one form of artwork that you'll find gracing the walls-watercolors.
Creating artwork using watercolors is one of the most popular ways of capturing beautiful scenery, painting life-like portraits and studying still-life objects. However, an unfortunate side effect of using watercolors is that they begin to fade over time, and as the years go by there is a risk of these masterpieces being lost to us forever. But just how do we prevent these wonderful paintings from disappearing? Well, thanks to the advances of modern technology, we now have the ability to scan watercolors, capturing every detail of them in the process and then saving them in a digital form.
Not only does this help to preserve the artwork in a very modern way, but when these digital captures are uploaded to a website, it offers the public more chances to appreciate them. One such website is Water colour World, which is one of the many organizations supported by Javad Marandi, one of the Joint Chairs of the Marendi Foundation which helps to provide opportunities in education, and supports some of the most vulnerable communities in the United Kingdom, as well as art and cultural initiatives. Scanning watercolors is certainly a lot more advanced than the usual scanning you might be more familiar with. Keeping the liveliness of the painting, the depths of the colors requires the correct equipment, software and a great eye for detail.
If you're an artist and you'd like to digitize (数字化) your watercolors through scanning, or if you're generally interested in how it's achieved, we've broken down the process below to give you a better idea of how art is transformed from paint to pixels (像素)!

The proof-of-concept design, described in Science of Food, combines a multiwavelength laser cooker, roughly the size of five smartphones put together, with a microwave-oven-sized food printer. Beyond applying complex substance and presentation designs, this type of software-controlled setup could someday scan a QR code to automatically prepare dishes adapted to individual eating habits and dietary requirements, says Blutinger, lead author of the paper and a digital-cooking researcher at Columbia.
The new technology is “astounding”, says Megan Ross, a food scientist who studies 3-D printing at Ireland’s University College Cork and was not involved in the study. Ross notes that the design is still at an early stage and that many technical challenges still remain, such as preventing cross contamination (交叉污染) between layers of uncooked and cooked meat. Still, Ross is impressed by the device’s ability to produce foods outside the kingdom of traditional cooking. “Is this going to be sold in shops everywhere in the next few years? No,” she says. “But everyone has to start somewhere.”
Compared with 3-D-printed chicken cooked in a traditional oven, the laser-cooked chicken had nearly twice as much weight and size, the researchers found. “That chicken is going to be juicy,” says Liam Macleod, a Denver-based chef (厨师) and former 3-D food printing specialist at the Culinary Institute of America who was not involved in the study. Macleod does not think such technology will ever replace chefs, but it might “add a tool to their collection” to deliver a new sensory experience. “Cooking is a skill set that has been practiced and perfected for thousands of years,” he says. “It’s very exciting to come up with something new and unique that people haven’t experienced yet.”

【推荐2】To persist, life must reproduce. Scientists at the University of Vermont, Tufts University, and the Wyss Institute for Biologically Inspired Engineering at Harvard University have discovered an entirely new form of biological reproduction and applied their discovery to create the first-ever, self-replicating (自我复制的) living robots.
Named Xenobots after the African clawed frog from which scientists take their stem cells, the machines are less than 0.04 inches wide——small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups. They even have regenerative capabilities; when the scientists sliced into one robot, it healed by itself and kept moving.
The Xenobots could potentially be used toward a host of tasks. Xenobots could be used to clean up radioactive waste and collect microplastics in the oceans. Some Xenobots had holes in their center, which could potentially be used to transport drugs or medicines. Traditional robots “degrade (降解) over time and can produce harmful ecological and health side effects," researchers said in the study, which was published in the Proceedings of the National Academy of Sciences. As biological machines, Xenobots are more environmentally friendly and safer for human health. Aside from these immediate practical tasks, Xenobots could also help researchers to learn more about cell biology——opening the doors to future advancement in human health and longevity.
While the prospect of self-replicating biotechnology could spark concern, the researchers said that the living machines were entirely contained in a lab and easily destroyed, as they are biodegradable and regulated by experts."There are many things that are possible if we take advantage of this kind of plasticity (可塑性) and ability of cells to solve problems,”said Joshua Bongard, one of the lead researchers at the university of Vermont.

【推荐3】Booking your next vacation to space with out-of-this-world views could soon be a reality. Orbital Assembly Corporation announced two new station concepts designed with space tourism accommodations. One of the stations, called Pioneer, could orbit Earth as early as 2025.
The Gateway Foundation circulated ideas for a space hotel in 2019. The goal of the stations is to run a space business park that can serve as a home away from home with room for offices and tourists. Orbital Assembly was founded by the Gateway Foundation team as a way to help make these dreams come true.
The proposed Pioneer station can accommodate 28 people. The second station, Voyager, scheduled to open in 2027, can hold up to 400 people. “The goal has always been to make it possible for large numbers of people to live, work and thrive in space,” says Orbital Assembly’s COO Tim Alatorre.
Both stations look like a wheel and will feature artificial gravity that allows guests to move comfortably on each station. Pioneer features five modules built around the rotating “Gravity Ring” architecture design. Tourists may still feel some weightlessness but will also be able to drink out of a cup and won’t have to be tied to a bed to sleep. The gravity works similar to how a spinning bucket pushes the water out to the sides of the bucket and stays in place, Alatorre explains. Near the middle of the station, there will be no artificial gravity, but gravity gradually increases further away from the center.
While the Pioneer station will be smaller than Voyager, guests can still shower, eat and drink sitting down in areas with gravity. Each station is furnished like luxury hotels on Earth. Voyager will feature a restaurant and suites with views of Earth.
A significant barrier to space travel is the cost. However, Orbital Assembly expects tourists to seek a trek into space as space travel eventually becomes less expensive. “We envision our Pioneer and Voyager space stations as the ultimate ecotourism destinations. Once people get to space, it will change their perspective about Earth,” Alatorre says. “Space travel is still at its early stage, and we’re excited to do our part to push it forward to help improve life on Earth.”

【推荐1】An afternoon nap (午睡) is one of the joys of life, although too much napping is not very good. In some cultures, people will have a daily nap — this is fine. The warning comes when people start sleeping during the daytime, when they did not before. There is certainly a good reason to believe that daytime sleepiness — as in the Alzheimer’s study (阿兹海默症) — can be a marker of a potential condition.
For most people, napping during the day is mainly a sign that you are not getting enough sleep at night, says Dr. Neil Stanley, a sleep expert. “If you feel sleepy during the day, you should think about taking a nap. That is what the body needs — it doesn't need to be kept awake with caffeine, it needs sleep. ”The feeling to notice is “sleepiness”, he says, not “tiredness”, which could be more psychological and linked to stress.
So how do you nap well? The key thing, says Stanley, is how long your nap lasts. Choose either a 20-or 90-minute nap. “When you fall asleep, you'll quickly go through the lighter stages of sleep into your first period of deep sleep. You don't want to wake up in deep sleep because that’s when you wake and feel worse than you did before. ”Napping for 20 minutes means you will wake up before you go into deep sleep; napping for 90 minutes means you’ll complete a sleep cycle.
Once you calculate the time it takes to fall asleep — some people are better at napping than others but, says Stanley, “a healthy adult will fall asleep in between 5 and 12 minutes” — you can set an alarm, allowing a 30- to 40-minute period for a short nap, and up to two hours for a longer one.
A good time to nap is during the body’s natural circle in the afternoon, between 2 pm and 4 pm. “You don’t really want to be napping much past that because then you are going to consume your night-time sleep,” Stanley says. The point, he stresses, is to get good night-time sleep, which would ensure you probably don’t need to nap at all.

【推荐2】As the Intergovernmental Panel on Climate Change (IPCC) states, if we are to avoid a world that is too hot to live in, we need to do everything we possibly can, right now, to cut greenhouse gas emissions into the atmosphere. The fashion industry (时装行业) contributes up to 10% of global emissions — more than international aviation (航空) and shipping combined. It also contributes to biodiversity loss, pollution, landfill issues unsafe work practices and more.
It’s not the first time that people have adapted their clothing in response to the demands of a crisis. During the second world war, clothing styles changed in the United Kingdom and Australia. To protect precious resources, shorter skirts, minimal detailing and a focus on practicability became the norm.
In our current context, the most helpful thing we can do is to buy fewer new clothes, wear them for longer and restrain our desire.
Australians buy a lot of clothes, about 56 items per year on average. That makes Australians the second highest textiles consumers in the world after the USA. The price of clothes has dropped significantly over the past couple of decades, and the number of clothes people have in their closets has grown.
The Berlin-based Hot or Cool Institute suggests a wardrobe (衣柜) of 74 garments ( including shoes but excluding undergarments) is typically sufficient for people who live in a two-season climate (in the tropics) and 85 pieces for those who live in a four-season climate, as most Australians do. If we buy 10 to 12 new items a year, we can replace our entire wardrobe in about seven years.
If we do care about sustainable (可持续的) development, that means changing those choices that are no longer suited to the climate crisis. Clothes need to reflect a person’s situation as well as their identity to “work” well. This may mean that what we wear changes as we make different buying decisions, just as people did in the second world war. We may start to look different, but that change means our values in action.

【推荐3】Household appliances and consumer electronic products witnessed strong sales during last year’s Spring Festival holiday, as stay-at-home consumers purchased cutting-edge (尖端的) digital products to keep themselves entertained or to send wishes to family members in other cities.According to the Ministry of Commerce, sales of communication equipment and household appliances rose by 39 percent and 29.9 percent respectively during the seven-day holiday.
Ma Ke, a white-collar worker in Beijing, did not go back to her hometown in Wuhan, Hubei Province during the holiday.Instead, she bought a 5G smartphone and a smartwatch for her parents as New Year gifts.“My father is a fan of electronic products.He always wants to be an early user of the latest phones and smartwatches,” Ma said.Consumers like Ma answered the call to stay where they work during the holiday period in a bid to reduce the potential spread of the COVID-19.While staying put, they bought the latest digital products and adopted cutting-edge digital technologies.Some of them also bought new fitness equipment, as the stay-at-home-fitness trend was booming in China.
Sensing many consumers did not travel during the holidays, shopping malls also came up with new ideas to better entertain them.Shopping malls in Shenzhen and Beijing, for instance, set robots powered by artificial intelligence (AI) to issue a variety of coupons (优惠券) for dining, movies, sports and other activities to attract consumers.
Jacky Han, vice-president of marketing at tech company Cheetah Mobile, said shopping malls played a central role in the retail ecosystem.“AI-powered robots set there can help merchants to turn foot traffic into intelligent data, by functioning as an interactive advertising platform and information desk and improving the customer experiences,” Han said.

【推荐2】Language and culture are connected to each other in so many ways: language names and explains important events and people. When the Fourth Earl of Sandwich (1718-1792) ordered a lunch (so that he didn’t have to leave the gaming tables) there was no word to refer to the bread-and-butter-encased food that has ever since borne his name. Another example is grog, a drink of rum(朗姆酒)mixed with water. The word was coined from the nickname(绰号)of Admiral Edward Vernon (1684-1757)—Old Grog. The nickname came from the cloak(披风)of “ grogram ” which he habitually wore, and it provided the word for watered-down rum which he gave to sailors. In Australia it has become the word for alcoholic(含酒精的)drink of any kind. Both sandwich and grog are known throughout the English-speaking world, and have been borrowed into other European languages—sandwich into French, and grog into German.
In Australia some rather more specialised foods go by the names of local heroes and heroines. The lamington owes its name to Charles Wallace Alexander Napier Cochrane-Baillie, Second Baron of Lamington, who was governor of Queensland from 1896 to 1901. He was well-known for his concern for the treatment of local workers in northern Qucensland. Another sweet, Peach Melba, was invented in 1892 or 1893 by the French cook Auguste Escoffier at the Savoy Hotel, London, to respect the Australian singer Nellie Melba.
Some words have their origin in the sports world. The boxer Larry Foley (1849-1917) stopped boxing at the age of 30, having developed a training school for young boxers. His name is probably the one behind the expression “give someone Larry Dooley". Also a sporting hero was the footballer Roy Cazaly (1893-1963), who is the person in “ Up There Cazaly ” , used well beyond football as an expression of encouragement. He became a great footballer by taking amazingly high marks for the St Kilda and South Melbourne clubs.

【推荐1】When I was a child, I dreamed of becoming many things. Sometimes, I wished I was an astronaut going up into space, finding new planets and jumping around in a cool space suit. Other times, I imagined being a cowboy in the Wild West, wearing stylish cowboy boots. On other occasions, I pretended to be a famous footballer, using my skills to score lots of goals for my team.
Looking back, I realize that imagination is a wonderful thing. I was able to create entire environments and scenarios in my head, using nothing more than my brain, and to be able to adapt things in my everyday surroundings to fit the specific story of the day. Growing up with siblings (兄弟姐妹) also helped, as it meant that even bigger stories could be created, combining our ideas and putting our thoughts into action. It also allowed for more varieties in the stories, as sometimes I could be the hero while on other occasions, I would be the bad guy.
One of my all-time favorite memories as a kid was playing in my back garden. I played the role of Indiana Jones, which cleaned up at the cinema at that time, with my younger sister as my assistant and my brother as a bad person. We used everything in our garden, from the path to the fence, as part of the storyline to create obstacles that needed to be overcome, and we would keep the story going for hours!
My personal favorite game was Indiana Jones and the Stolen Easter Eggs, where my brother hid small chocolate eggs around the garden and my sister and I had to find them by answering questions or solving a puzzle. It was difficult, but eventually we found all the eggs and shared them together.
Since then, I have seen many great things and met many amazing people. The elements of fun and varieties of my creative imaginations are what I try to bring into every part of my positive life. So I can enjoy sharing with and hearing about other people’s stories, too.

【推荐2】This commercial kitchen in central London prepares one-and-a-half thousand meals a day. It provides catering for a museum and a conference centre. Kitchens like these typically throw away 20% of the ingredients they buy. Some are thrown away even though they are edible. And sometimes food ends up in the bin simply because it's not needed after all.
To stop this happening, this kitchen has been using a new piece of technology which can simply be connected to a normal bin on scales (磅秤). This is what’s known as a smart bin. Kitchen staff use it like a supermarket self-checkout. The idea is to keep an accurate digital record of the food being thrown out. This helps the head chef make more informed choices.
Bill Owen, head chef said, ''It was a shocker how many tons are actually saved through using this. '' By keeping an eye on exactly what kind of food is being thrown out, the chef can not only adjust his orders of ingredients, but also make whole new menus based on what was previously being thrown away. ''In an operation where you make a significant amount of your food in advance, you can typically cut food waste in half. '' Mark Zornes Winnow added.
Do people actually have time to sort the food as they are putting it into the bin? They do. To start with, take a little while to get used to the bin system. It is just about familiarizing yourself with where the buttons are.
However effective they may be, there is one important factor that holds these smart bins back. Andrew Stephen, CEO of Sustainable Restaurant Association, explained, ''Traditionally, smart bin technology has been at quite a high price point for particularly small operators. There is only a relatively small part that can afford that upfront implementation (安装启用). '' It seems that smart bins are just one part of the solution to the pressing problem of food waste.

【推荐3】People who are cheerful and relaxed are less likely to suffer from colds.It's possible that being full of vim and vigor helps the body fight illnesses,say the researchers from Carnegie Mellon University(CMC)in Pittsburgh.
"We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,"says psychologist Sheldon Cohen,the study's lead researcher.
In a previous study,Cohen and his colleagues found that people who tended to be cheerful and lively were least likely to develop sniffles,coughs and other cold symptoms.People who showed positive feelings were also less likely to mention symptoms to their doctors,even when medical tests detected those symptoms.
Those findings were interesting,but they didn't prove that a person's attitude affects whether he or she gets sick.Instead,it was still possible that a person's underlying personality is what matters.
Evidence suggests,for instance,that certain people are naturally more likely to be outgoing and optimistic,with high self-esteem and a sense of control over life.This would mean that who we are,not how we feel,ultimately decides our chances of catching colds.
To figure out which mattered more,personality or emotions,the researchers interviewed 193 healthy adults.The researchers talked to each person over the phone every evening for 2 weeks. They told the researchers about the positive and negative feelings they had experienced that day.
The results showed that everyone in the study was equally likely to get infected.Their symptoms,however,differed depending on the types of emotions that they had reported over the previous fortnight.
Among those who reported good moods and had been infected with the flu virus,for example, 28 percent developed coughs and stuffy noses.On the other hand,those symptoms struck 41 percent of people who had been less positive.Scientists argue about whether negative emotions or positive emotions have a stronger effect on how healthy we are.For now,it can't hurt to look on the bright side more often than not!
