1 . Scientists have discovered more than 5,000 new species living on the seabed in an untouched area of the Pacific Ocean that has been identified as a future hotspot for deep-sea mining, according to a review of the environmental surveys carried out in the area.
It is the first time the previously unknown biodiversity of the Clarion-Clipperton Zone (CCZ), a mineral-rich area of the ocean floor that spans 1.7m sq miles between Hawaii and Mexico in the Pacific, has been comprehensively documented. The research will be critical to assessing the risk of extinction of the species, given contracts for deep-sea mining in the near-pristine area appear imminent.
Most of the animals identified by researchers exploring the zone are new to science, and almost all are unique to the region: only six, including a carnivorous sponge and a sea cucumber, have been seen elsewhere.
Contracts for mining exploration in the CCZ have been granted to 17 deep-sea mining contractors in an area covering 745,000 sq miles. The companies, which are backed by countries including Britain, the US and China, want to dig for minerals including cobalt manganese and nickel in part to sell to the alternative energy sector.
To better understand the impact of mining this fragile ecosystem and its newly discovered inhabitants, an international team of scientists has built the first “CCZ checklist” by compiling all the records from expeditions to the region. Published in the journal Current Biology, it includes 5,578 different species, of which an estimated 88% to 92% had never before been seen.
To study and collect specimens (样品) from the ocean floor, biologists have joined research cruises in the Pacific that send remote-controlled vehicles to traverse (穿越) the seabed 4,000 to 6,000 meters below. Adrian Glover, a deep-sea biologist at the NHM and senior author of the study described it as an “incredible privilege”. The expedition, funded through the Natural Environment Research Council and others, is backed by UK Seabed Resources (UKSR), a deep-sea mining company that operates the UK’s exploration area. The scientists watch operations by video link direct from the boat as new species are gathered by remote control vehicles in the darkness below.
The seabed, Glover said, is an “amazing place” where, despite the extreme cold and dark, life thrives. “One of the characteristics of the abyssal plain is the lack of food, but life has a way of persisting down there,” he said, “It’s a mystery.” One of the deep-sea animals discovered was nicknamed the “gummy squirrel”, because of its huge tail and jelly-like appearance, he said. There are also glass sponges, some of which look like vases.
With approval for deep-sea mining looming, Glover said he believed it was “imperative that we work with the companies looking to mine these resources to ensure any such activity is done in a way that limits its impact upon the natural world”.

2 . China’s space industry has made great achievements, which makes us occupy a place in the world space field. After 11 years, China has finally completed its Tiangong space station with the docking (对接) its Mengtian lab module, establishing the Tiangong as the second operational space station apart from the US-led, multinational International Space Station.
On November 1, the Mengtian lab module, the third and final part of its Tiangong space station docked with the core Tianhe module 13 hours after being launched. Next, the Tianhe and Mengtian modules will dock with the Wentian lab module, completing Tiangong’s T-shaped basic structure. The 17.88-meter-long, 23-ton Mengtian module is the heaviest operational single-cabin (舱) active spacecraft in orbit. Mengtian consists of a work cabin, a goods airlock cabin, a payload cabin and resource cabin. In addition, it has eight scientific experiment rooms and 37 extravehicular (舱外的) installation (安装) options.
One of the more ambitious aims of China’s space program is to position the country as a leading provider of space-based international public goods and services, such as planetary defense. Last month, Asia Times reported about China’s plans to conduct its first asteroid (行星) direction-changing test in 2025 or 2026. China has also taken pioneering steps in Mar exploration. A good example is the completion of China’s Tianwen-1 Mars mission. China has also stated that it is willing to share scientific data from its Tianwen-l mission at an appropriate time and that scientists are welcome to apply for research over the data.
Moreover, China has also announced plans to send men to the moon, helping its future settlement and economic use. And China and Russia plan to establish a permanent moon base by 2027. The base, the International Lunar Research Station, is seen as an experimental complex designed for multiple scientific activities.
Reflecting China’s open-door space policy, the Tiangong is designed to be “inclusive” and adaptable for foreign astronauts.

3 . Discover Jiangsu
Known as the land of water, China’s coastal province of Jiangsu has all the geographical advantages to give it a starring role in the epic (史诗般的) tale of China’s ancient Maritime (海上的) Silk Road. With busy port cities, historic sites and breathtaking natural beauty, Jiangsu is the perfect place to follow the story of this remarkable trade route.
Nanjing and the voyages of Zheng He
At the beginning of the Ming dynasty, the city of Nanjing in Jiangsu was declared capital of China. Besides building one of the longest city walls in history, the emperor ordered the construction of vast “treasure ships” in 1403. Under Zheng He’s command, the ships finished seven epic ocean voyages, reaching as far as the east coast of Africa.
Nantong and overseas trade
In Jiangsu’s port city of Nantong, goods have flowed in and out of the province by water for centuries. Beyond Lusi Port Town, a busy seascape of boats travel on the waters of Jiangsu’s coast. It’s a scene that shows how China’s historic Maritime Silk Road remains successful until this day.
Yancheng and unspoiled nature
Salt was one of the commodities (商品) that played a key role in the history of trade in Jiangsu, contributing to the wealth of the province. A major source was the tidal (潮汐的) salt flats of Yancheng, which literally means “salt city”. This remarkable landscape also plays host to some rare bird species like cranes, egrets, and spoonbill sandpipers.
Yangzhou and the spread of Buddhism
In the Jiangsu city of Yangzhou, a Tang-dynasty monk by the name of Jianzhen set sail to Japan to spread the teachings of Buddhism. Daming Temple, where Jianzhen lived, can still be visited today.

A lesson in trust
“Come on, Tuck,” I said, patting the floor of the 4Runner (越野车). “Load. Let’s go for a walk.” Tuck danced nervously at my feet, then sat and looked up at me with sad eyes. He wouldn’t jump in.
This was my first afternoon with the three-year-old border collie (德国牧羊犬) I was adopting, and it was time for the daily hike.
I’d taken Tuck in reluctantly, as a temporary solution for Tammy, my friend. She was trying to find a new home for the dog. Tuck was adopted from a pet store and had been kept long in a cage there, leaving him long-lasting trauma (创伤).
Tammy knew why I wasn’t willing to give Tuck a permanent home. Three months earlier, I’d lost my beloved Bantam, the border collie who’d been my rock for 12 years. I wasn’t ready to let a new dog into my life for good. But I’d agreed to help Tammy out while she continued her search.
Tuck wouldn’t load, no matter how much I coaxed (劝诱). Knowing there was always a reason for a dog’s behavior, I finally lifted the dog up and placed him in the back. “Load,” I said, teaching him the command. “Good boy.”
But every day, when it came time to load for our hike, Tuck still didn’t trust my invitation. At the end of the second week, I became impatient.
Actually, Tuck was a sweet dog and seemed to love everyone. He had this boyish enthusiasm toward strangers.
Days crept into a third week. I found myself appreciating Tuck for who he was. One afternoon, he came to the steps where I sat. He shyly looked at me, then walked over and put one big foot on my knee. At that very moment, I realized that he did show affection, in his own way. But he still refused to load for our hike.

The increased use of light-emitting diodes (LED) and other forms of lighting are now brightening the night sky at a dramatic rate. Research has revealed that light pollution is now causing the night sky to brighten at a rate of around 10% a year, an increase that threatens to ruin the sight of all but the most brilliant stars in a generation. A child born where 250 stars are visible at night today would only be able to see about 100 by the time they reach 18.
Physicist Christopher Kyba, of the German Centre for Geosciences told the Observer. “A couple of generations ago, people would have regularly encountered this glittering (闪耀) vision of the universe—but what was formerly universal is now extremely rare.” Nevertheless, the introduction of only a modest number of changes to lighting could make a considerable improvement, Kyba argued. These moves would include ensuring outdoor lights are carefully capped, point downwards, have limits placed on their brightness, and are not predominantly blue-white but have red and orange components.
The problem is that light pollution is still not perceived by the public to be a threat. As Professor Oscar Corcho, of Universidad Politécnica de Madrid, has put it: “The negative consequences of light pollution are as unknown by the population as those of smoking in the 80s.”
Yet action is now urgently needed. Apart from its astronomical impact, light pollution is harming human health. “When reddish light shines on our bodies, it stimulates mechanisms including those that break down high levels of sugar in the blood. Since the introduction of LEDs, that part of the spectrum (光谱) has been removed from artificial light and it is playing a part in the waves of obesity (肥胖) and rises in diabetes cases we see today,” said Prof Fosbury from University College London (UCL),
UCL researchers are preparing to install additional infrared (红外线) lamps in hospitals and intensive care units (ICU) to see if they have an effect on the recovery of patients who would otherwise be starved of light from this part of the spectrum.

8 . From the moon to Mars, scientists have been looking for water —the key to life —in the solar system for decades. Recently, they have turned to Jupiter (木星)!
On April 14, the European Space Agency’s (ESA) JUICE spacecraft successfully lifted off from French Guiana in South America. JUICE, short for “Jupiter Icy Moons Explorer”, will collect data from Jupiter and its three moons, Europa, Ganymede and Callisto.
The three moons are believed to have big oceans of liquid water under their icy shells. According to ESA, the water on these moons could be as much as six times the amount in Earth’s oceans. The mission “will change our understanding of the solar system”, wrote Scientific American.
In 1998, NASA’s Galileo spacecraft found that Europa might send water as far as 160 kilometers into space. That gave scientists the idea of studying the icy moons of Jupiter.
The oceans under these moons are likely to be tens of kilometers deep. But they are also trapped under tens of kilometers of ice, making it very difficult to study them. Although JUICE cannot land on the surface, it has lots of high-tech equipment to study the moon’s environment, including spectral imaging (光谱成像) tools and radar. They could give more data on things like the thickness of the oceans, their salt content, and their distance from the icy shells above, reported Phys.org.
“The main goal is to understand whether there are habitable (可居住的) environments among those icy moons and around a giant planet like Jupiter,” JUICE team member Olivier Witasse said during a press conference on April 6.

9 . Every winter, Siberian cranes (白鹤) migrate from northeast Siberia in Russia to Poyang Lake in Jiangxi province, China. About 95 percent of the birds spend the season there. However, climate change has endangered the birds’ habitats.
“In some years, the Poyang Lake experiences floods, while in others, it experiences droughts. Both of these create food shortages in the cranes’ habitat,” Qian Fawen, a researcher from the National Bird Banding Center of China, told China Daily.
To help deal with the problem, the local government has built 70 hectares of lotus roots (莲藕) in Nanchang to provide food during the winter for the cranes. The birds’ population has risen from about 3,000 to more than 5,000 over the past 20 years, according to Qian.
Over the years, China has worked hard to protect migratory birds and wetlands. Known as the “Earth’s kidneys (肾脏)”, wetlands play a key role in cleaning water, preventing floods, and helping with biodiversity. The Wetlands Protection Law was introduced on June 1, 2022. It stops building work on important national wetlands and bans activities such as overgrazing (过度放牧) and giving out wastewater.
Thanks to these efforts, China has reported more birds wintering in the nation’s wetlands. In February, black-faced spoonbills (黑脸琵鹭), an endangered species, were seen wintering at Dongting Lake after disappearing for five years. Last December, Shanghai Chongming Dongtan Bird National Nature Reserve recorded more than 2,900 tundra swans up from some 1,000 seen during the winter of 2021.
