Research identifies protein that signals flowering in squash plants

...e nature of the florigenic signal has eluded plant biologists for over 70 years, owing to the difficulties attendant with the accurate detection and measurement of compounds in phloem sap, and designing experiments to allow accurate monitoring of long-distance transport of potential signalling compounds in plan...

Simulations unravel outer membrane transport mechanism

... studies had been inconclusive, however. Molecular biologists have difficulty studying systems that involve complex interactions between proteins, particularly when one domain moves into and out of a structure like a beta-barrel, said biochemistry professor Emad Tajkhorshid, principal investigator on the study....

Columbine flowers develop long nectar spurs in response to pollinators

...engths of the pollinators that drink their nectar, biologists have found. The researchers were Justen Whittall of the University of California at Davis and Scott Hodges of the University of California at Santa Barbara. They were funded by the National Science Foundation (NSF). Their results appear in this week...

The kapok connection -- Study explains rainforest similarities

...bers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago. Research by University of Michigan evolutionary ecologist Christopher Dick and colleagues shows...

Prey not hard-wired to fear predators

...ay fear. That is a critical piece of knowledge as biologists and public agencies increase efforts to re-introduce large carnivores to places where they have been exterminated. Berger’s study is published in the latest issue of the journal Conservation Biology. The goal of re-introduction isn’t simply to sa...

This grant will enable Dr Twarock to expand her group and fund three postdoctoral positions and four PhD students. The group will collaborate closely with the Astbury...

MIT's ocean model captures diversity of underwater forests

...ocean systems in a way that is consistent with how biologists think of them-water filled with millions of diverse microbes that wax and wane in relative abundance through interactions with each other, and the environment, as dictated by natural selection," said Chisholm. Indeed the guiding principle of the n...

Tibetan antelope slowly recovering, WCS says

...er Aili Kang and a team of Tibetan and Han-Chinese biologists and field assistants, counted nearly 9,000 Tibetan antelope or chiru, more than expected. This may indicate an increase in some places for this endangered species, according to Schaller. At the same time, the team witnessed no direct evidence of th...

Researchers learn what sparks plant growth

...s, a member of the mustard family that is to plant biologists what the mouse is to mammalian geneticists. "How do organisms decide when to grow and when to stop growing? These questions are especially important in plants because they are rooted in the ground and must alter their shape and size in response to...

Brown cancer biologists identify major player in cell growth
