A representative survey of more than 2,000 U.S. adults finds that 30 percent of Americans say their personal religious beliefs conflict with science, while 68 percent say there is no conflict. A majority(59 percent) say science and religion often conflict, while 38 percent say science and religion are mostly compatible. 

Belief of a conflict between science and religion does break along lines of religious belief - but not how most people think. The most religious people do not see a conflict with science, it is instead people on the other side who think the most religious people must be against science - that science and religion are in opposition - that increase belief in a conflict between them.

A study published today shows that a newly studied class of water contaminants that is known to be toxic and hormone disrupting to marine animals is present likely due in part to indirect effects of human activity. The contaminants are more prevalent in populated areas in the San Francisco Bay, suggesting that human impacts on nutrient input or other changes in water quality may enhance natural production.

A paper in PLOS ONE says humans may have an indirect effect on water quality.

Computers have scanned aerial photographs and conducted the first automated mass-crowd count in the world, thanks to the work of researchers at the University of Central Florida.

Counting large-scale crowds has been a long, tedious process involving people examining aerial photographs one at a time - and it has been termed accurate, with organizers often claiming results 1000% greater than police and journalists. They are able to make claims and stick to them because the traditional method involves dividing photographs into sections and counting the number of heads per inch. 

Bee colonies had a decline in 2006, and a decade earlier, and lots of times going back as far as people kept count of bees, but activists most recently blamed a group of pesticides called neonicotinoids, and ignored climate and parasites, the thing that scientists said made the difference in periodic blips.

Regardless of the consensus, a team of scholars in Environmental Science&Technology blame these "neonics" and claim past studies may have underestimated the bees' exposure to the compounds.

Heart valve replacements made from tissue (bioprosthetic valves) have long been thought to be spared the complication of blood clot formation. Researchers have now found that about 15 percent of all bioprosthetic aortic heart valve patients develop blood clots on the leaflets affecting valve opening, regardless of whether the patient received the new valve via open-heart surgery or a minimally-invasive catheter procedure, a new study from the Cedars-Sinai Heart Institute shows.

The study, published online today by the New England Journal of Medicine and scheduled for the Nov. 26 print edition, also shows that anti-coagulant medications such as Warfarin quickly resolve the clotting issue for all patients, regardless of the type of valve or procedure.

Repeating aloud boosts verbal memory, especially when you do it while addressing another person, says Professor Victor Boucher of the University of Montreal's Department of Linguistics and Translation. His findings are the result of a study that will be published in the next edition of Consciousness and Cognition. "We knew that repeating aloud was good for memory, but this is the first study to show that if it is done in a context of communication, the effect is greater in terms of information recall," Boucher explained.
