Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback. In 2020, the industry produced salmon feed ingredients using up to 144,000 metric tons of small pelagic fish caught along the coasts of West Africa, where they could have fed between 2.5 million and 4 million people, according to the report. The analysis comes as the industry faces a wave of public opposition after revelations of high mortality rates and the sale of fish deemed unfit for human consumption, along with accusations of antitrust violations by the European Commission.

The creature was tiny, about the size and color of a grain of rice. Dan Distel, director of the Ocean Genome Legacy Center at Northeastern University in Boston, wasn't exactly sure what it was, other than a mussel of some kind. He put the wee bivalve in a petri dish and asked a colleague to set it aside. "By the time we got back to the lab, the little bugger had crawled out of the dish," he recalls with some chagrin. "And we couldn't find it." It was months later that they found another one, and Dr. Distel realized that the mussel looked oddly familiar. It resembled the giant mussels found at deep-sea hydrothermal vents 1,500 feet below the ocean's surface, which have gills that contain bacteria that let the mussels gain nutrients from corrosive hydrogen sulfide bubbling from the Earth's crust. But this mussel was tiny and pale and, strangest of all, lived a mere 60 feet or so down. DNA analysis soon confirmed that this mussel was a new species, whic

One day, the boss was offered a job making plastic watch straps for a client in the Middle East. He turned it down because there wasn't enough profit in it for him but asked my father if he wanted to take the job and even supported him to set up a factory.

Photo: Harry Chan Tin-Ming Too cool for school By the time I was four, my father had a factory in Cheung Sha Wan, in Kowloon, making plastic flowers. By 1960, he was one of the four big plastic flower producers in Hong Kong. Later, he opened a factory in Taipei because he had a lot of relatives in Taiwan. I didn't enjoy it at all. I cried a lot and wet my bed. I tried all sorts of things to try to get out of school. One time, I said I was sick and put warm water in my mouth so that when they checked my temperature, they thought I had a fever and sent me to the hospital in Happy Valley. When I was given a test, I just put my name on

Meilan Solly Associate Editor, History When giant pandas Mei Xiang and Tian Tian arrived at the Smithsonian's National Zoo and Conservation Biology Institute (NZCBI) in December 2000, they surprised keepers with their seemingly boundless energy. "Their activity level wasn't anticipated," said a staff member at the time. "Even though the Zoo has had pandas before"—Ling-Ling and Hsing-Hsing, who came to the United States in 1972—"they were different ones, and older." One morning, 2-year-old Mei Xiang (pronounced may-SHONG) climbed an electrical conduit on the outside of her habitat and tucked herself under the building's overhang. She and he

Abstract Habitat associations underpin species ecologies in high-diversity systems. Within tropical, shallow water coral reefs, the relationship between fishes and corals is arguably the most iconic and highly scrutinized. A strong relationship between fishes and reef-building hard corals is often assumed, a belief supported by studies that document the decline of reef fishes following coral loss. However, the extent of this relationship is often unclear, as evidenced by conflicting reports. Here we assess the strength of this ecological association by relying on literature that has surveyed both fishes and corals synchronously. We quantitatively synthesize 723 bivariate correlation coefficients (from 66 papers), published over 38 years, that relate fish metrics (abundance, biomass and species richness) with the percentage of hard coral cover. Remarkably, despite extensive variation, the pattern of association on a global scale reveals a predominantly positive, albeit weak (| r | &
