2 . The world’s first named heat wave hit Seville, Spain, pushing temperatures past 110 degrees Fahrenheit and earning the most severe tier (级别) in the city’s new heat wave ranking system. Heat wave “Zoe” has brought burning temperatures to the southern part of the country for the last few days, particularly the area where Seville is located.
Zoe is the first named heat wave to hit Seville since it officially used a new system last month to name and rank heat waves, similar to hurricanes (Climatewire, June 22). Only the most severe heat waves get names, named this year in reverse (颠倒的) alphabetical order. After Zoe come Yago, Xenia, Wenceslao and Vega. The worst of the heat is expected to begin tapering off (减弱) today, but it has already posed a significant risk to human health.
Seville’s new ranking system takes a three-tiered approach to categorizing heat waves, with Category 1 as the lowest ranking and Category 3 as the most severe. The system has specific criteria for each category, involving not only daytime temperatures, but also nighttime lows, humidity and the heat’s expected effects on human health.
Spain has been struggling with extreme temperatures for much of the summer already. High heat broke local records around the country last month, and the first two weeks of June were the hottest on record in the country. Across the continent, this year was Europe’s second hottest June on record. Extreme heat returned again earlier this month. Cities across Spain broke monthly temperature records and wildfires broke out on the landscape.
Climate change is causing heat waves to become more frequent, more severe and longer-lasting all over the world, increasing the risks to human health. Seville’s new naming and ranking system is intended to raise public awareness about the dangers of extreme heat.

5 . Nothing feels more like summer than a neighborhood barbecue. But the annoyance of summer gatherings remains: the buzzing(嗡嗡声) of mosquitoes around our ears.
“The buzzing in your ear is mostly just a side effect of the mosquito's wings beating,” said Michael Riehle, a professor at the University of Arizona. “The sound doesn't have a long range, so you notice it most when they are flying around your ears.”
“From a distance, mosquitoes track carbon dioxide that we give out.” Riehle told Live Science. “They fly back and forth to follow that concentration level back to the source.”
But in fact, that buzzing you hear is likely from a female mosquito. That's because male and female mosquitoes lead very different lives. The males typically hang out and feed on the sweetest part of flowers; they couldn't care less about the humans wandering about. The females, however, need to find a blood meal in order to have enough energy to produce eggs.
As she approaches, the female mosquito zeros in on body heat and the carbon dioxide to land on the victim. The female mosquito uses taste sensors on her feet to determine whether the human, or any blood-bearing animal, is adequate to tap for her next meal.
But while we feel mosquitoes buzzing around our ears, Riehle noted that most mosquitoes are not attracted to our heads. Rather, these bloodsuckers may be more likely to seek out our feet, which have bacteria that give off attractive smell to mosquitoes. However, most people probably don't notice a mosquito buzzing around their ankles, he said.
Another study found that female mosquitoes were more attracted to men who had less diverse bacteria on their skin than to men with more diverse skin bacteria; these bloodsuckers also prefer those who wear dark colors, such as black.

6 . One billion people in the world are short of water. How can this problem be solved. Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is abundant. (Suggestions such as these prove extremely expensive when they are actually used.) One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage. Although many questions must be answered before such a project could be tried, moving icebergs seems a reasonable possibility in the future.
Engineers, mathematicians, and glaciologists from a dozen countries have been considering the iceberg as a future source of water. Saudi Arabia is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 square mile) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how to insulate the iceberg remains an unsolved problem.
The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends above the water — most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops. Thus they would be much easier to move.
How can a 200-million-ton iceberg be moved. No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods could be driven into the ice. What would happen if the iceberg splits into several pieces during the pulling. Even if an iceberg with very few cracks were chosen, how could it be pulled through stormy waters. Furthermore, once the iceberg reached its destination, very few ports would be deep enough to store it.
All of these problems must be solved before icebergs can become a reasonable source of water. Yet scientists estimate that it will be possible to transport them in the near future. Each year, enough icebergs form to supply the whole world with fresh water for a full year. In addition, icebergs are free and nonpolluting. As a solution to the world’s water problems, icebergs may be a workable possibility.

7 . Most animals living in crowded conditions have particularly strong immune systems, so it long puzzled researchers that honeybees do not.
Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by moving parts of proteins from disease-causing pathogens to them before they are laid. These act as antigens to trigger the development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place? Dr. Harwood wondered if the nurse bees were taking in parts of pathogens and passing them to royal jelly they were producing while eating the food brought to the hive.
To test this idea, he teamed up with a group at the University of Helsinki, in Finland, led by Dr Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with baby bees to look after. Instead of honey, they fed the nurses on sugar water, and for three of the hives they added P. larvae, a bacterium causing a hive-killing disease, to the sugar water.
In this case, to stop such an infection happening, Dr Harwood and Dr Salmela heat-treated the pathogens and so killed them in advance. They also labelled the dead bacteria with a fluorescent dye, to track them easily. And, sure enough, it was confirmed that parts of P. larvae were getting into royal jelly released by those bees which had been fed with the sugar water containing that.
All told, these findings suggest that nurse bees are indeed, through their royal jelly, passing antigens onto the queen for vaccinating her eggs. They also mean the nurses are vaccinating baby bees as well, because baby bees, too, receive royal jelly for the first few days after they come out.

9 . One of the greatest challenges in caring for such intelligent animals as chimpanzees (猩猩) is providing them with enriching experiences. Every day, the chimpanzees at Project Chimps receive morning and evening food-based enrichment devices, but caregivers are always looking for more ways to keep the chimps mentally engaged. With 79 chimpanzees, each with their distinctive personality, care staff often find that different chimps react differently to new enrichment.
Last year, we began inviting musicians to perform for chimps to see what they may respond. A violin performance received quite the response. Additional musicians were lined up to visit but the coronavirus has stopped the activities, which we hope to resume in the near future.
This past week, we brought an electric piano for the chimps to investigate. Some chimps, like twins Buttercup and Clarisse, were immediately interested and could not wait to tap out a few notes. Others, like Emma, were more interested in trying to take it apart.
29-year-old Precious has very little tolerance for the piano. She sat off to the side for a few minutes, but eventually she decided that was enough. She called an end to the enrichment session by throwing a handful of waste at the piano. Receiving her message loud and clear, we removed the piano.
We could never have guessed how 33-year-old Luke would react to it. As with many retired lab chimpanzees, Luke has some anxiety issues. He seems particularly distrustful of anything new, including people, food, and enrichment. But when we presented the chimps with the piano, Luke was the first to investigate. We could not believe our eyes—this usually anxious chimpanzee bravely chose to explore something new!
To us at Project Chimps, this is what it is all about: giving chimpanzees the freedom to choose. We are honored to be part of their journey.

10 . British sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has put over 850 massive artworks underwater worldwide. On February 1, 2021, Taylor launched his latest work---The Underwater Museum of Cannes.
“The main goal was to bring attention to the fact that our oceans need our help,” Taylor told Dezeen. “Ocean ecologies have been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.”
The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages. They range from Maurice, an 80-year-old fisherman, to Anouk, a 9-year-old student. Towering over 6-feet-tall and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask. The mask indicates that the world’s oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile to careless human activities.
Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago. Besides removing the trash, Taylor also restored the area’s seagrass. Just one square meter of the seagrass can generate up to 10 liters of oxygen daily. The seagrass also helps prevent coastal erosion and provides habitats for many ocean creatures.
“The idea of creating an underwater museum was to draw more people underwater and develop a sense of care and protection,” Taylor told Dezeen. “If we threw unwanted waste near a forest, there would be a public outcry. But this is happening every day in our surrounding waters and it largely goes unnoticed.”
