The narwhal (Monodon monoceros), an iconic whale of remote Arctic waters, is widely known for its long, spiral tusk, which is really an elongated tooth. The tusk, which is predominantly found in males and can grow up to 10 feet long, is one of the most fa
阅读全文动物植物为什么熊猫不多吃肉？竹子中发现的分子可能是它们以植物为基础的饮食背后的原因
Giant pandas have digestive systems that are typical for carnivores. Yet, bamboo is their main source of food. They have evolved several features; for example, pseudo thumbs to grasp bamboo and flat teeth that are well suited for crushing it, that make it

A team of biological, Earth and environmental scientists from North Carolina State University, Stellenbosch University and the University of Minnesota has found new types of ancient eggshells in the Mussentuchit Member in Utah. Their study is published in
阅读全文动物植物一个亟待解决的问题：如何拯救太浩湖的一片原始森林
On the shores of Lake Tahoe at Emerald Bay State Park grows what some consider to be the most iconic old-growth forest in the Lake Tahoe Basin. Giant ponderosa pines—some of the last remaining in the area—share space with at least 13 other tree species.

More than 99% of birds can fly. But that still leaves many species that evolved to be flightless, including penguins, ostriches, and kiwi birds. In a study in the journal Evolution, researchers compared the feathers and bodies of different species of flig
阅读全文动物植物当蛋白质罢工时：酵母菌落揭示了生命中一些最基本过程中隐藏的作用
A basic business principle is that no worker is irreplaceable; that also holds true for most proteins, the cellular factory workers of our bodies. If we fire a protein—that is, permanently delete it from our genome using genetic engineering—the cell will
阅读全文动物植物基因转换可以帮助控制贫瘠土壤中的叶片生长
A new study has identified a genetic circuit in plants that controls individual leaf growth and allows the plants to adapt to their environment. The findings could help the development of more drought-resistant crops.
