1 . A warbler weighs about the same as four pennies, but twice a year makes an extraordinary journey. It flies nearly 4,000 miles between Canada’s spruce forest and its wintering grounds in northern South America.
A new online atlas (地图册) of bird migration, published recently, draws from a huge number of scientific and community data sources to illustrate the routes of about 450 bird species in the Americas, including the warblers. The Bird Migration Explorer mapping tool , available free to the public, is an ongoing collabration (合作) of 11 groups that collect and analyze data on bird movements, including the US Geological Survey and the National Audubon Society.
For the first time, the site will bring together online data from hundreds of scientific studies that uses GPS tags to track bird movements, as well as more than 100 years of bird- banding data collected by USGS. “The past twenty years have seen a true renaissance in different technologies to track bird migrations around the world,” said Peter Marra, a bird migration expert.
The site allows a user to enter a species — for instance, osprey — and watch movements over the course of a year. For example, data from 378 tracked ospreys show up as yellow dots that move between coastal North America and South America as a calendar bar goes through the months of the year.
Or users can enter the city where they live and click elsewhere on the map for a partial list of birds that migrate between the two locations. For example, ospreys and 12 other species migrate between Washington, D. C. and Fonte Boa, Brazil.
As new tracking data becomes available, the site will continue to expand. Melanie Smith, director for the site, said the next phase of expansion would add more data about seabirds.

3 . What time is it on the Moon? Since the dawn of the space age, the answer has been: It depends. For decades, lunar missions have operated on the time of the country that launched them. However, as different countries plan lunar missions, the current system has been considered unsustainable.
The solution is a lunar time zone. Creating a time zone up there may simplify things. The main objective of establishing a universal timekeeping system for the Moon is to make the contact among the various countries more efficient.
The discussion about how to do that is happening as things are starting to get busy on and above the lunar surface. A lunar lander from one country is set to arrive on the Moon. Another lander, from a different country, is expected to land on the South Pole of the Moon. These missions, along with other possible lunar landings, are happening as a space agency prepares to send four astronauts into orbit around the Moon. China completed the construction of its own space station and previously hinted that Chinese astronauts would be on the Moon by 2030. With increased exploration comes the potential for miscommunication.
“These missions will not only be on or around the Moon at the same time, but they will often be interacting as well — potentially passing communications for one another, performing joint observations or meeting up,” stated a space agency. For all those interactions to happen smoothly, the missions will need to operate on a standardized time, the agency said.
“This idea of timekeeping on the Moon is important because it shows the international development of the Moon,” an expert said. “Precision timekeeping was key to travel on the Earth, and it’s key to travel between the Earth and the Moon.”
A universal timekeeping system for the Moon is needed, but many details remain to be worked out. One of the questions that has yet to be settled is whether lunar time should be set on the Moon or matched with the Earth.
Once a new lunar time zone is established, the methods used to create it will be useful for future space exploration. Astronauts can go to Mars in the next two to three decades and will face similar hurdles that a Martian time zone could address.

4 . Many schools have disaster plans in place to help students prepare for a natural disaster and know what to do immediately after one occurs. Here are some additional tips for you.
Create a “go” bag.
When you know a natural disaster is coming, having a “go” bag can help you move to safety quickly when it’s time to evacuate (撤离) .
Sign up for your school’s text notification system.
In the moments after a disaster, it’s important to make sure you’re okay. If you do have cuts or scrapes (擦伤) , use the first aid kit to attend to these wounds.
Stay in a safe place.
In lots of natural disasters, many accidents happen after the worst of the event due to people being out and about too quickly.
A.Check yourself for injuries |
B.Make contact when possible |
C.If it’s something more serious |
D.If the building you are staying in is destroyed |
E.Think of what you need and cannot live without |
F.Be really careful not to put yourself in any further danger |
G.Getting real information timely is critical at moments of crisis |
5 . Rock climbing has become a mainstream pleasure enjoyed by many. The natural world offers a thrilling adventure through beautiful environments filled with wildlife.
However, rock climbing happens in places that are generally hard to access and unsuitable for agricultural expansion and urbanization. As a result, they have generally suffered less human impact and the areas tend to be important sites for biodiversity.
Some cliff- specialist plant species have very narrow ranges. If a suitable habitat is rare, they have few opportunities to grow elsewhere. However, climbers can remove vegetation and soil when establishing a route that has not been climbed before.
The number of climbers heading out to these cliffs is increasing at an astonishing pace. It is essential for climbers to know what they can do for the protection of the cliff ecosystem.
A.This can wipe out the cliff ecosystem that was there previously. |
B.And some organizations have an online database offered to check. |
C.Therefore, every climber is responsible for protecting the cliff ecosystem. |
D.Even climbers can ask the climbing gym to organise a discussion about this topic. |
E.Seemingly a straightforward way is to spread the word about these good practices. |
F.These data can then be accessed by scientists to avoid environmental issues on cliffs. |
G.For example, 40% of sport climbing areas in Spain are found in nature protection areas. |

10 . For shelter dogs, awaiting adoption can be stressful. Roughly 4.1 million dogs enter animal shelters in the United’ States every single year. Dogs housed in shelters can face great stress due to noise and limited spaces, which can reduce their overall well-being and impact their adoptability. A study published in the journal PLOS ONE found that dogs kept together with companions showed fewer signs of stress and were even adopted more quickly.
“Despite being a social species, dogs are often housed alone in shelters to reduce disease transmission and possible injury from inter- dog conflicts. But this practice can work against dogs’ behavioral health and adoptability,” study co-author and Virginia Tech University animal behavior psychologist Eric a Feuerbacher said in a statement.“ We wanted to examine whether pair housing could be a useful intervention for improving shelter dogs’ welfare.”
Prior studies have suggested that co-housing can produce behavioral and physiological benefits. These studies have typically focused on laboratory dogs or dogs housed for more than six months at veterinary (兽医的) schools. However, those results might not necessarily apply to shelter dogs, many of which have shorter lengths of stay than those dogs studied. This study is the first to examine how U. S.-based shelter dogs perform in co-housing vs. single-housing.
This new study followed 61 dogs, most of which had recently entered the Humane Society of Western Montana. The team placed half of the dogs in co- housing with partners who were put together after a compatibility (兼容) test. The other half were housed alone.
They observed the dogs over a week, recording common stress behaviors. These include lip-licking and pulling back their ears. The team also took daily samples of the dogs’ urinary cortisol (尿皮质醇) to measure for biological indicators of stress.
The dogs that were housed with a companion showed fewer stress behaviors. They were also adopted four days sooner than the single-housed dogs on average. “Many potential adopters might already have a dog,” Feuerbacher said. “Clearly exhibiting that a dog can successfully interact with other dogs might highlight those dogs as good matches — leading to more successful adoptions.”
