7 . More than 50 percent of the largest lakes in the world are losing water, storing less water than they did three decades ago, according to a new assessment published today in Science. The key causes are not surprising: The warming climate and unsustainable human consumption.

Lead author Fangfang Yao, a climate fellow at University of Virginia, and his team created a technique to measure changes in water levels of nearly 2,000 of the world’s biggest lakes and reservoirs (水库), which represent 95 percent of the total lake water storage on Earth.

They used 250,000 lake-area pictures taken by satellites between 1992 and 2020 to survey the area of 1,972 of Earth’s biggest lakes. They collected water levels from nine satellite altimeters (测高计) and used long-term water levels to reduce any uncertainty. For lakes without a long-term level record, they used recent water measurements made by newer instruments on satellites. Combining recent level measurements with longer-term area measurements allowed scientists to reconstruct the volume of lakes dating back decades.

The result was staggering: 53 percent of lakes globally experienced a decline in water storage. The authors compare this loss with the size of 17 Lake Meads, the largest reservoir in the United States.

To explain the trends in natural lakes, the team used recent advancements in water use and climate modeling. “Climate change and human water consumption were mainly responsible for the global net decline in natural lake volume and water losses in about 100 large lakes,” Yao said. “And many of the human and climate change footprints on lake water losses were previously unknown, such as the dryness of Lake Good-e-Zareh in Afghanistan.”

And their research offers an understanding into possible solutions. Yao said, “If human consumption is a large cause of lake water storage decline, then we can adapt and explore new policies to reduce large-scale (大范围) declines.” This happened in one of the lakes the team studied, Lake Sevan in Armenia. Lake Sevan has seen an increase in water storage, in the last 20 years, which the authors linked to the enforcement (实施) of conservation laws on water withdrawal since the early 2000s.

8 . Researchers have trained a robot “chef” to watch and learn from cooking videos, and recreate the dish itself.

Grzegorz Sochacki, a PhD in Bio-Inspired Robotics Laboratory, and his colleagues designed eight simple salad recipes and filmed themselves making them. They then used a publicly available neural network (神经元网络) to train their robot chef. The neural network had already been programmed to identify a range of different objects, including the fruits and vegetables used in the eight salad recipes.

Using computer vision techniques, the robot analyzed each frame (画面) of videos and was able to identify the different objects and features, such as a knife and the ingredients (佐料), as well as the human demonstrator’s arms, hands and face. Both the recipes and the videos were changed to vectors (模型) and the robot performed mathematical operations on the vectors to determine the similarity between a demonstration and a vector. By correctly identifying the ingredients and the actions of the human chef, the robot could determine which of the recipes was being prepared. The robot could infer that if the human chef was holding a knife in one hand and a carrot in the other, the carrot would then get cut up.

Of the 16 videos it watched, the robot recognized the correct recipes 93% of the time. The robot was also able to detect that slight changes in a recipe, such as making a double portion (份) or normal human errors, were changes and didn’t mean a new recipe. The robot also correctly recognized the demonstration of a new, ninth salad, added it to its cookbook and made it.

“Our robot isn’t interested in the sorts of food videos that are popular online, which quickly move back and forth between the person preparing the food and the dish they’re preparing—they’re simply too hard to follow,” said Sochacki.   “But as these robot chefs get better and faster, they will be able to use those videos to learn a whole range of recipes.”

9 . On April 10, the University of Utah became officially Bee Campus certificated. This process was started by senior Zoē Bross in her second year on campus. Bee Campus USA hopes to protect the native pollinators (传粉者) on college campuses by increasing the number of native plants, providing nest sites, reducing the use of pesticides, and offering educational opportunities that help with pollinator conservation.

After first hearing her school wasn’t certificated a Bee Campus and finding becoming Bee Campus certificated would give the University more point s on the Advancement of Sustainability in Higher Education Sustainability Tracking, Assessment & Rating System (STARS) program, which decides ratings to campuses according to their sustainable efforts, Bross wanted to help.

There are many requirements to become Bee Campus certificated. The first major step for Bross was to create a standing Bee Campus committee with a mix of students and staff. Bross tried to reach out to professors and people specializing in this field. After many efforts, the program was finally passed through and a garden for it was created.

Over 100 people showed up to help plant in the garden. After the planting was done, Grounds, responsible for planting the pollinator gardens, set up their hydroseeder (水力播种机) and let attendees take turns spraying the hill, with a mixture of water and wildflower seeds, making the area more pollinator-friendly. Rocky, the school robot, even made an appearance, taking turns spraying.

Certificated by Bee Campus USA, Bee Campuses are expected to continue maintaining or improving pollinator habitats on campuses, as well as maintaining an educational online presence. “I see the campus continuing to be very interested,” Bross stated.

Future plans for the campus include more pollinator gardens, native wildflowers, and even bee sculptures to provide new habitats. As for Bross? She pictures herself somewhere warm and sunny in the near future, working in environmental communications and doing something for the change she wants to see in the world.

10 . A school Picture Day usually occurs either once in the fall, or twice a year during both the start of the fall and spring terms. A school Picture Day is you and your children’s chance to record and keep memories for the school year. Missing a Picture Day means missing out on joy and special moments of the childhood—so it’s important to plan ahead.

Hairstyle

Don’t get a new haircut right before the Picture Day. If you’re planning your children’s haircut for the Picture Day, make sure it gets done at least two weeks before the Picture Day. This will ensure that any bad spots have time to grow back before the photos.

Try to stick to a neutral haircut. Recent trending hairstyles, colors and other unique hairstyles may not go well. You should find a hairstyle that is both neutral and something that represents your children’s personality.

Keep the hair out of their face. If your children’s hair naturally falls in front of their face, try to use hairpins, hair spray, or even a fresh haircut to keep their bright smile shining through.

Clothing

Dress for the weather. If it’s cold outside, you should make sure your children arrive at school in clothing that keeps them warm. On the contrary, if the Picture Day is scheduled on a forecast heatwave, dressing your children in warmer clothing (even if it’s your favorite one) could result in sweat showing up in the photos.

Don’t make your children wear anything they don’t like. They’ll shine in clothing they’re comfortable in, but will look obviously less comfortable in one they don’t like. Help your children show their best side by letting them wear clothes they love.

Accessories (配饰)

Keep jewelry minimal. You never want children’s jewelry to distract from their photos. If they do want to wear some sort of jewelry, make sure that it’s small or understated.

Avoid hats. Hats do little help, other than covering up your children’s head and face and should never be included.
