2017/9/19
Researchers reveal how a group of trap-jaw ants can snap their jaws shut at speeds of up to 50 miles per hour – just fast enough to capture their elusive prey.
They report their findings in the Journ...

Keeping honeybees healthy is critical to the world’s food supply.A lack of adequate nutrition for bees is blamed as one of many possible causes for colony collapse disorder — a mysterious syndrome tha...
Genetic mechanism found for fish adaptations to pollution
Genetic mechanism fish pollution
2016/2/23
A Washington State University biologist has found the genetic mechanism that lets a fish live in toxic, acidic water. The discovery opens new insights into the functioning of other “extremophiles” and...

cysteine dioxygenase iron mechanism cofactor kinetics
2014/12/12
Cysteine dioxygenase (CDO) is a non-heme iron enzyme that can be found in mammalian tissue. It is mainly localized in the liver but is also present in the brain, kidney, and adipose tissue. CDO conver...
The Signaling Mechanism of TGF-β1 Induced Bovine Mammary Epithelial Cell Apoptosis
TGF-β1 ALK-5 p-Smad2/3 [Ca2+]i Mammary Epithelial Cell
2016/5/9
The present study showed that Transforming growth factor beta 1 (TGF-β1) can induce apoptosis of bovine mammary epithelial cells. This apoptosis was also observed with phosphorylation of Smad2/3 withi...
