6 . Different photoreceptors (视细胞) in the eyes can affect how we see the world around us. Animals including bees and some birds can see ultraviolet light (紫外线) that human eyes cannot see. By reconstructing the colors that we know animals can see, scientists can learn more about how they communicate and find their position. Getting an accurate view of what animals are seeing has been a challenge, but a camera system developed by scientists at the University of Sussex in the United Kingdom and George Mason University in Virginia could help ecologists and filmmakers create videos that closely copy the colors that different animals see in their natural environments.
The camera system builds on the current technique called spectrophotometry. By using this technique, images are taken at specific wavelength ranges that are typically beyond what humans can see. However, using the method can be time-consuming, produce false colors, require specific lighting conditions, and can’t always capture (拍摄) something that is moving. To overcome some of these limitations, the team developed a camera and software system that captures animal-view videos of moving objects under natural lighting conditions.
One of the cameras records videos in four different color channels at the same time: blue, green, red, and UV. That data is then processed into perceptual units using a popular programming language called Python. This generates a more accurate video of how animals see those colors. The team tested this new system against the traditional spectrophotometry methods and their new system predicted the perceived colors with an accuracy of over 92 percent. “Our project was quite involved, and we had many surprises along the way,” says Daniel Hanley, a leading researcher. “The most surprising thing that we discovered was how much clouds can impact an observed color. We didn’t tend to notice these shifts, but they were notable.”
“We plan to apply the camera system as broadly as possible. Currently, we are exploring a range of applications,” says Hanley. “Our hope is that through community engagement our designs can improve and we will gather many novel observations about colors in nature.”

7 . Oaks Farms is a combination of experiences that are designed to keep your students engaged in fun and exciting learning opportunities. We are truly a classroom without walls, offering educator-developed programs and field trips. We invite you here to explore sustainability (可持续发展), which includes not only the environment but also animal welfare, safety and our community.
The Pig Adventure
This program will help you learn all about pork and its benefits and discover the growth cycle of pigs from little babies to full grown-ups. Monitor the development of baby pigs and see how the farm works at the Pork Education Center. You will get first-hand knowledge about how our feeding system works.
The Dairy Adventure
This program encourages you to play as you learn, by opening up a fun space for dairy discovery including learning how to use a “real” station. Understand the nutrition of the animal products, and how robots are used in the Voluntary Milking System. You can start at the entrance to the adventure, and then stop by our Birthing Barn, which is an independent education center, and take a look inside.
The Crop Adventure
Explore the Crop Adventure program to learn about the importance of working to feed
8 billion people, the many uses of corn outside of consuming it, and how we can be sustainable with limited resources. See how a tractor (拖拉机) can tell you about the nutrients in the soil. Explore how technology assists farmers and the amazing biodiversity on the Farmer’s Garden.

8 . In today’s not-so-golden time of domestic air travel, checking a suitcase for free is a luxury afforded to few. And those who do check their bags often find themselves stressing out during the whole journey, wondering if their luggage (行李) is actually going to arrive at their destination with them. As a result, more travelers than ever are choosing to bring their belongings into a carry-on bag — many of them big and heavy, with wheels.
The result? A boarding free-for-all (混战), as nervous flyers wait around the gate hoping to be among the first to get on the plane — all to get a tiny piece of overhead space near their seat. Unfortunately, the older versions of those highly desired bins (柜) were not designed with your average carry-on roller suitcase in mind. They must be laid down flat, leaving a small space above them that is of little use, while taking up a good piece of bin space.
Enter French aircraft maker Airbus launches its new “Airspace L Bins” designed to be refitted in only three to five days. These specially shaped overhead compartments (隔层) promise to create 60% more cabin luggage space than traditional systems. How? Simply by allowing travelers to load their carry-on roller bags vertically (垂直地) instead of having to lay them flat. Made of ultra-lightweight composite (复合的) products, the refit reuses many parts of the original bin including the sidewall, ceiling and lighting to cut down on waste.
Flight attendants will likely approve of the new compartments too, knowing they can complete boarding procedures while hearing far fewer complaints from flyers about how they don’t have a place to store their bags.
Luggage has long been a contentious and complicated issue in the aviation world, and that doesn’t appear set to change with or without bigger bins. In the end, regardless of traveler preferences, most would agree that if better-designed bins can speed up the time we spend getting on and off the plane, we’re all for them.
