A debate continues among scientists over whether tree composition in forests in eastern North America historically have been influenced more by climate or by cultural burning, which is the intentional and controlled use of fire by Indigenous people to man
阅读全文动物植物生长缓慢的细菌对环境反应更敏感
Researchers led by Professor Erik van Nimwegen at the Biozentrum, University of Basel, have discovered a new mechanism in bacteria that controls their response to prevailing environmental conditions. They derived their theory from a simple yet interesting
阅读全文动物植物影响果蝇性别比的自私基因具有独特的自限性机制
When a species reproduces, typically, each parent passes on one of their two versions (alleles) of a given gene to their offspring. But not all alleles play fair in their quest to be passed onto future generations.

Our attraction to sugar has grown to an unhealthy level. The average person in the United States now consumes more than 100 pounds of the sweet stuff every year, up from 18 pounds in 1800.
阅读全文动物植物在出现耐药性的情况下，酶可以恢复抗生素的作用
Bacterial resistance negates the effect of antibiotics in the treatment of infection. Using mouse models, researchers now show that if antibiotics are administered with an enzyme called endolysin, the combined effect protects against infection by resistan
