阿根廷出土之泰坦巨龍化石或為地表最大動物
In January 2021, it was announced that paleontologistsat a dig site in Argentina had uncoveredthe fossilsof a 98-million-year-old Titanosaur, and experts believe the dinosaur may be the largest creature to have ever existed on Earth. The Titanosaur species are categorized as sauropods, which were large quadrupedherbivoreswith long necks and long tails.
At the time of the report, the team excavatingthe fossil in northwest Patagonia had only uncovered 24 vertebraefrom the tail and some of the animal’s pelvicand pectoral girdle. Based on the visible skeletalremains, the researchers estimatethat this particular dinosaur was around 122 feet long and weighed about 90,000 kilograms. Other similarly large sauropods have been found in the region, including the Patagotitan and the Argentinosaurus.
Scientists Create Milk Product from Yeast

On January 6, researchers at Tel Aviv University reported that they had produced cow’s milk in a lab from yeast. The professors behind the project—who have also created a startupcompany called Imagindairy—stated that their goal is to find a way to produce dairy products with fewer damagingeffects on the environment than traditional dairy farms. They hope to create milk that has the same nutritionalbenefits of animal milk, along with a normal smell, taste, and texture. The scientists are working to turn yeast cells that have been encodedwith milk DNA into factories that can produce milk proteins. They believe this procedurewill allow them to produce milk quickly and economically.
