动物植物濒临灭绝的北方白犀牛的基因组为该物种的复兴带来了希望
The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce.

A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an occurrence that has never before been reporte

Roots "feel" gravity to extend and anchor themselves in the soil, but they can alter their growth direction toward a water source when needed. However, according to a new study by scientists at the Institute of Science and Technology Austria (IS

When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better wi

Nestled in dark burrows, with a limited sense of vision, mice brush their whiskers against their environment to navigate and to detect objects around them. This behavior, termed whisking, has been extensively studied in the past few decades and has tradit

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is the first model of amni
