Pollination find could lead to cordgrass control
... oaks and pine trees need the wind to carry pollen between
plants, fertilizing nascent seeds. Scientists guessed that wind pollination was efficient, but the theory hadn't been tested. "People think, because they get hay fever, there's always plenty of pollen in the air," said Heather G. Davis, lead author ...
British scientists exclude 'maverick' colleagues, says report

'inside' and 'outside' and believed that controversial scientists needed to be placed outside the community so as to not gain scientific legitimacy. Swedish scientists were more inclined to ensure that all members 'have their say'. They were more lik...
