1 . African penguins live on the rocky coasts of South Africa, Namibia and nearby islands. Like other types of penguins, the birds have white feathers covering their chests and black feathers covering their backs. They form lifelong pair bonds with mates, but they nest in huge colonies — so, scientists wondered how the birds were able to identify their partners among the sea of black-and-white birds. They wondered if their chest spots had something to do with it. To test this theory, they studied 12 African penguins at a zoo and marine park near Rome called Zoomarine Italia.

In one test, they hung two life-size photographs of the African penguins. One showed a random member of the colony, while the other showed the test subject’s mate. The scientists recorded the birds’ interactions with the photos: How long did they spend looking at each one, as well as how much time did they spend standing near each photograph? The penguins spent more time gazing at the photo of their partners — about 23 seconds longer, on average — than looking at the other photo. They also stood next to the image of their beau s for twice as long. Then, the researchers covered up the heads of the birds in the photographs, leaving only their speckled bodies visible, and the penguins still lingered near their partners’ portraits.

In another experiment, the researchers hung up two photos of a bird’s mate — but, in one, they had digitally removed its spots. In this case, the penguin again spent more time looking at the photo with the dots.

Finally, the researchers posted two photographs of penguins with digitally removed spots — one of the test subject’s mate and the other of a random penguin from the colony. In this scenario, the penguins did not appear to recognize their partners. They spent roughly the same amount of time gazing at or standing near both photos.

Together, the results of these experiments suggest African penguins are zeroing in on their partners’ spots and using them like name tags, scientists say.

“Our results provide the first evidence of a specific visual cue responsible for spontaneous individual recognition by a bird and highlight the importance of considering all sensory modalities in the study of animal communication,” the researchers write in the paper.

3 . Nanjing Yunjin brocade is traditional Chinese silk art with a history of about 1,600 years. Its complex weaving techniques, various colors and patterns, and its particular choices of materials make it valuable and ancient people said, “An inch of brocade, an inch of gold.” Today, the traditional characteristics and unique skills of yunjin remain to be an award-winning art treasure. Its techniques are passed down from generation to generation by artisans.

Zhou Shuangxi, a national-level inheritor of yunjin weaving techniques, is one of them. Back in 1973, he graduated from a mining school and was selected to become a student at the NanjingYunjin Research Institute along with five other students, just because he was “in good shape”. There were only several masters in their 70s and not even a loom (织布机) to use. “The old masters finally remembered a loom was stored somewhere. When I opened the door, I saw what seemed like a pile of wood,” Zhou recalled.

“Weaving was difficult, but different from mining. Mining requires heavy physical labor, but working with the soft and thin silk requires studying and practicing in front of a loom for decades until you master the technique. My hands became quite awkward due to mining, so I used to put my hands in warm water whenever I could. In this way, they could become softer and weave the silk more easily,” he said.

Out of the six or so students, Zhou is the only one who has insisted on the trade to this day. Having devoted the past five decades to yunjin production despite all the sweat and struggles, he has developed his techniques to the point where he can weave the antique dragon robes in all their small details. He also made various artworks that not only show China's intangible cultural heritage but also serve as Zhou Shuangxi's artistic creations.

“I am lucky to be in such a good era and I have the honor of being a representative inheritor,” Zhou said.

4 . Four Top Family Camping Trips

Camp Clearwater in White Lake, North Carolina, features its own 1, 100-acre lake complete with 1, 300 feet of shorefront. On-site facilities here include a mini-golf area, sports fields and a park that allows pets. Further, the family campground hosts various activities, including games, cornhole tournaments and golf cart parades. Overnight campsites run from $40 to $60 per night.

Those cager to try tiny living in a natural setting should check out this tiny location in the heart of the Catskills Mountains region. There are on-site facilities including a pool, a dog park, kayaks, massage services and even goat yoga. You can spend your time walking on the waterfront trails or relaxing on a boat. Rates start at $295 per night for tiny homes that sleep two, but some tiny homes with more space for additional guests or amenities（便利设施） cost more.

The Meeman-Shelby Forest State Park features 12, 539 acres of outdoor space along the Mississippi River. This area is known for its magnificent trees as well as the many endangered and protected plants that call it home. You can camp here in a two-bedroom cabin（小木屋） or on one of the 49 campsites. Cabin rentals start around $110 per night, and you can rent a camping spot for as little as $25 per night.

Families within close driving distance to the Florida Everglades have plenty of outdoor options to consider, including houseboat and eco-tent rentals through Flamingo Adventures. Houseboat rentals sleep four adults and two kids maximum and prices start at $350 per night. Eco-tents, which sit on platforms and feature bed linens, electricity, sitting areas and plenty of storage, start at $50 per night.

5 . There’re plenty of fresh fruits and vegetables available in local markets. But while those red juicy strawberries look fresh, consumers have no way of knowing how long the fruit can be stored at home. The same goes for distribution centers and supermarkets.

Now, the food technology startup OneThird, located in the Netherlands, is looking to change that with an infrared (红外线) scanner that can accurately predict how long fresh fruits and vegetables will last. The startup is named OneThird because one-third of food is wasted due to spoilage (变质) every year.

The startup’s founders were inspired by a UK company that uses this type of technology in the medical field and decided to see if it was applicable for food. “I looked at the challenges in the food-supply chain and found out that 40 percent of food waste is fresh produce. One of the biggest causes of waste is that nobody knows shelf life.” founder and CEO of OneThird, Marco Snikkers said.

Quality inspections at farms and distribution centers are done manually (手动地). An inspector checks the fruits and vegetables and makes notes about the size and quality. Then the food is sent to consumers without considering travel time or how long the produce will remain usable.

Using the infrared scanner at the distribution center means that inspectors can use the information to approve shipments that will ensure the produce can be distributed on a timely basis. This means that a shipment of rip e tomatoes will not be sent long distances away.

OneThird’s scanner combines the technology of optical scanners, image modeling, and Artificial Intelligence to provide accurate shelf-life predictions.

The startup found that the technology can reduce up to 25 percent produce waste that was caused by spoilage. “Global food waste has an enormous environmental impact; reducing global food waste cuts global greenhouse gas emissions and promotes global food security,” said Jacob Smith, a climate expert from the University of Maine.
