A new angle on flowers: Fish are players in pollination
..."Much of the science of ecology is elucidating the surprising and counterintuitive connections among species," said Robert Holt, a UF professor of zoology and one of five authors. "What we've done here is elucidate a heretofore unsuspected connection of that sort." The research is significant in part because it...Did feathered dinosaurs exist?
...hat birds evolved from dinosaurs have reached some surprising new conclusions. However, they caution that "the problem of avian origins is far from being resolved." Their analysis is published online October 10, 2005 in the Journal of Morphology, published by John Wiley & Sons, Inc. and available via Wiley Inte...Geoscientists follow arsenic from chicken feed to streambeds
... to minerals in the soils and aquifer sediments, a surprising finding from water samples from streams receiving runoff is that low concentrations of arsenic are transported to streambeds instead of being retained by the aquifers, Schreiber said. "We think that the arsenic is adsorbed onto nanoscale particles th...Woods Hole Research Center scientist part of international initiatives to save the great apes
...t of the priority Great Ape populations. It is not surprising that 51 percent of those are found in Central Africa, says Laporte, as large tracks of forest habitat are still untouched by agriculture or logging. She adds, "The situation is changing fast, and we need to put in place operational forest monitoring ...New study weighs impact of open access on scholarly journals

In fact, page charges, charges for color images, reprint charges and other fees for authors are considerably more common among subscription journals, the study found....EU research suggests that PCBs damage sperm but finds no dramatic effect on male fertility
...Inuit men. "The results from the Inuit cohort are surprising and reassuring. As usual, we wanted a simple answer and instead we found a lot of new questions," said Dr Span, who is Group Leader, Reproductive Toxicology, Section of Toxicology and Biomedical Sciences at ENEA in Rome. "We can only speculate, at th......tone pre-mRNA processing machinery, and reveal the surprising involvement of common factors between 3'-end processing of poly(A)-lacking (ie. histone) and poly(A)-containing mRNAs. This paper identifies the long sought-after factor for histone pre-mRNA processing what has simply been known as the "heat labile ...Research: removal of dominant rivals causes male cichlid fish to undergo remarkable transformation

Weder notes that the surprising blood pressure-DRD4 findings could only have come about through collaboration between blood pressure specialists and behavioral geneticists. "We did not expect to have this result, because DRD4 is not considered a standard hypertension gene," he says...Javits Award funds neurology of animal movement study

We had to improvise with the tools that were available," Mickelsen said. "We learned from this small series how to improve the approach." They are devising better tools, such as ne......ists from The University of Arizona in Tucson. The surprising finding is good news for the environment. Arizona farmers who plant the biotech cotton known as Bt cotton use substantially less chemical insecticides than in the past. Insect pests sometimes evolve resistance to such chemicals in just a few years, a...Yale researchers make cell biology quantitative
...some work -- even in human or plant cells." "It is surprising that no one has made this calibration before. Biology has tended to be descriptive," said Pollard. "This technology is part of moving biology to be more quantitative and mechanistic.

"People had hypothesized that a complex of this kind must exist and had looked for it for many years, but until now it...Selective logging causes widespread destruction of Brazil's Amazon rainforest, study finds

"This was totally surprising to us and alarming to our colleagues, especially those interested in conservation, climate change and the ability of governments like Brazil to enforce environmental laws," he notes.

"The apparently novel catalytic activity of the enzyme may be a lucky side...Protein aggregates in Lou Gehrig's disease linked to neuron death

Morimoto believes this surprising finding indicates that the structure of aggregates associated with other neurodegenerative diseases such as Parkinson's and Alzheimer's will be found to be different as well. Looking at individual cells in a population, the researchers also found tha...Scientists determine how tumor gene controls growth

He adds "these new findings suggest the possibility that, in fact, some as yet unidentified subset of human cancers might actually be composed of a mixture of normal cells and cells with mu...Newly recognized gene mutation may reduce seeds, resurrect plants

Another somewhat similar mutant Arabidopsis showed alterations only in wax and seed development, but not in the other mutated RST1 traits.
