海洋微生物 共享 遗传信息 原绿球菌 光合生物 基因转移
2023/6/21
From the tropics to the poles, from the sea surface to hundreds of feet below, the world’s oceans are teeming with one of the tiniest of organisms: a type of bacteria called Prochlorococcus, which des...
Ateam of researchers led by Harvard and Broad Institute scientists has developed a new drug-delivery system using engineered DNA-free virus-like particles (eVLPs) that is able to edit genes associated...
Imagine a ball thrown in the air: It curves up, then down, tracing an arc to a point on the ground some distance away. The path of the ball can be described with a simple mathematical equation, and if...
The cost of DNA sequencing has plummeted at a rate faster than Moore’s Law, opening large markets in the sequencing space. Genomics for cancer care alone is predicted to hit $23 billion by 2025, but s...
