Researchers determine three-dimensional structure of PAPP-A

Danish researchers have determined the three-dimensional structure of the proteolytic enzyme PAPP-A. The results may allow us to better understand the basic biology that regulates linear growth of vertebrates. The same regulatory ...

Molecules that promote plant-to-plant communications below ground

Plants have evolved elaborate mechanisms for detecting neighboring plants, which typically involve the perception of "cues'" inadvertently produced by their neighbors. Strigolactones are hormonal signaling molecules that ...

No, the human brain did not shrink 3,000 years ago: research

How do plants adapt to aquatic environments?

The theory that life began in the ocean is widely accepted. The public, however, does not acknowledge the reality that many aquatic organisms are descendants of terrestrial organisms. Whales and dolphins are marine mammals ...

Which rules evolutionary change: Life or climate?

The fossil record over the last half a billion years shows biodiversity as a zigzagging pattern of species births and extinctions. For decades scientist have attempted to answer the question: Which rules supreme—life or ...
