2 . Fly on a lamp on a summer evening and, within minutes, insects will begin to gather near the lamp. This behavior has given rise to a popular simile (比喻) that describes attraction: “like a moth (蛾) to a flame.” Though insects have been “drawn” toward bright light sources for a long time, scientists never truly understood why. Now, they may finally have an answer.

Insects aren’t attracted to artificial lights, according to a new paper published Tuesday in the journal Nature Communications. Rather, the glow (光) might be interfering with their natural sense of direction. The insects you see circling street lights, in other words, are likely lost.

The new finding depends on a theory about navigation. When insects fly, they can experience whole body acceleration up to five times greater than the acceleration caused by gravity. As such, it can be difficult for them to know which way is up and which way is down as they fly through the air.

The study authors suspect insects rely on the glow coming from stars, planets and the moon to reorient (定方向) themselves. For most of Earth’s history, the sky was the brightest source of light at night, so flying insects turned their bodies to make their backs face skyward. But then, artificial light entered the picture.

To reach these conclusions, scientists used high-resolution cameras to film insects flying around artificial lights in Costa Rica. They also attached tiny sensors to dragonflies and moths, then filmed motion-capture videos of them in flight. Together, these methods allowed researchers to slow down the insects’ normally fast pace and study their movements in greater detail. The footage showed insects turning their backs toward sources of artificial light — even at the price of crashing.

If the light’s above them, they might start orbiting it. When they fly directly over a light, they fly themselves upside down and that can lead to crashes. It really suggests that the moth is confused as to which way is up. After running some experiments, researchers determined that light shining straight down provided the least disruption to insects’ flight. Lights that pointed straight up, on the other hand, caused the most difficulties.

3 . Every year, about 15 billion trees are cut down to make way for agriculture, mining, logging. and urban expansion. Such mass deforestation has accelerated global warming and endangered the survival of millions of species. Though many nations, organizations, and even individuals have tried, no one could plant enough trees to make up for that loss — but some innovative entrepreneurs are working on a high-tech solution.

BioCarbon Engineering (BCE), a U.K.-based start-up, has developed a technique that could plant one billion trees per year. The method? Drones (无人机). Current tree-planting programs "are just not fast enough," said Irina Fedorenko, a co-founder of the company. "But our technology is automated, so we can scale up quite realistically and quite quickly."

First, a drone scans the land and develops a 3-D map of the area. Then, using the data from this "smart map", the team develops an algorithm (算法) for a unique planting pattern. A drone uses the algorithm to carry out the planting strategy. The drone flies about six feet above the ground, firing growing seeds at a speed that will get them under the soil. The species planted by drone has a better survival rate than helicopter spreading that's more commonly used. Some species even have survival rates nearly identical to hand planting.

With GPS and imaging technologies, experts agree that drones have become useful for accurately mapping large areas of land and measuring tree growth. But some scientists are more skeptical about their success as a planting technology to tackle deforestation on a large scale. After all, they only have so much range and battery life.

"Drones are good for measuring secondary growth and looking at where the forest is coming back, but you fight deforestation at a socioeconomic level," says Arturo Sanchez, director of the University of Alberta's Center for Earth Observation and Sciences. "The issue of climate change is not forest restoration, the issue is energy. It is controlling coal plants, power plants, automobile emissions. Planting trees is very important, but when you look at the distribution of CO₂ emissions, deforestation accounts for 10 to 15 percent. The rest is energy. That's what needs to be controlled."

4 . In a heartwarming display of community spirit, six student lacrosse (长曲棍球) players from Roslyn High School in New York have come together to make sports more accessible for people with disabilities. The initiative, dubbed" Lacrosse My Heart," was started by a group of teenagers who were inspired to create a more inclusive environment for their peers with disabilities.

The program focuses on adapting lacrosse, a popular sport in the area, to meet the needs of individuals with physical and cognitive disabilities. The students have designed specialized equipment and rules to ensure that everyone can participate, regardless of their abilities. For example, they have created larger goals and lighter balls to make scoring easier, and have implemented modifications such as allowing players to use their hands to catch and throw the ball. These adaptations have made the sport more accessible and enjoyable for all participants.

The program has gained significant support from the local community, with many schools and organizations donating resources and volunteering their time. The students have also received guidance from experts in adapted physical education, ensuring that the program is safe and enjoyable for all participants. This collaboration has helped to create a program that is both inclusive and beneficial for everyone involved.

One of the key aspects of Lacrosse My Heart is its emphasis on building relationships between able-bodied students and those with disabilities. The founders wanted to create an environment where kids with disabilities could feel included and build friendships with their peers. This approach has been successful, with participants reporting increased confidence and social skills.

Lacrosse My Heart is not only providing opportunities for individuals with disabilities to participate in sports but also promoting understanding and acceptance among young people. By creating a welcoming environment and adapting sports to meet individual needs, these high school students are breaking down barriers and fostering a sense of community that goes beyond the playing field. Their efforts are not only changing lives but also inspiring others to create more inclusive spaces for individuals with disabilities.

5 . CitySprouts is a non-profit school garden program that works with public schools to build capacity to integrate the school garden into teaching curriculum and the school culture. CitySprouts Summer Program is based in Cambridge and provides 100 youth (ages 11-14) with hands-on learning through growing, harvesting, preparing and eating healthy food in an urban garden. With an emphasis on science, technology, engineering and math (STEM), the summer program fosters a strong connection to their natural urban environment through working and learning in the garden.

CitySprouts is seeking energetic, diverse, and outgoing college students to provide essential support to the Summer Program. We expect to accept 8-10 students as CitySprouts Summer Fellows for nine weeks during the summer. CitySprouts Summer Fellows can expect a significant learning opportunity as well as opportunities for career exploration.

Summer Fellow Responsibilities:

·Participate in weekly staff meetings
