How the Tibetan Plateau is helping us to understand the current and future climate
Imagine the conductor of a vast orchestra stood not at the front, but in the middle of all the musicians, dictating how they work together and the music they produce. The musicians are not stationary; they move past each other and interact, but all t.....»»
New technique zeros in on the genes that snakes use to produce venom
Only about 10% of the world's roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that's enough for snake bites to be an important public health concern. To help better understand how snakes make their venom and how ve.....»»
