Protein plays role in helping plants see light

Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between ...

Ancestors of land plants were wired to make the leap to shore

When the algal ancestor of modern land plants first succeeded in making the transition from aquatic environments to an inhospitable shore 450 million years ago, it changed the world by dramatically altering climate and setting ...

Scientists a step closer to developing renewable propane

Researchers at The University of Manchester have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. This research is part of a programme of ...

Biologists learn how plants synthesize their growth hormone auxin

Biologists at the University of California, San Diego have succeeded in unraveling, for the first time, the complete chain of biochemical reactions that controls the synthesis of auxin, the hormone that regulates nearly all ...

Study finds evidence for existence of elusive 'metabolon'

For more than 40 years, scientists have hypothesized the existence of enzyme clusters, or "metabolons," in facilitating various processes within cells. Using a novel imaging technology combined with mass spectrometry, researchers ...

Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...
