Evolutionary first: Parasite reaches beyond host to play havoc with others' sex lives

...s forests on opposite sides of North America, and, knowing that Wolbachia can affect reproductive isolation between species, he wondered whether the two species actually met each other in nature. A stretch of forest in Canada physically connected the eastern and western communities, so he set out to discover...

Hail to the hornworts: New plant family tree sheds light on evolution of life cycles

... Qiu said. "As humans, we're always interested in knowing where we came from and why we are different from other primates," Qiu said. "Now that we know, from phylogenetic analyses, that our closest relative is the chimpanzee, we can compare the chimpanzee genome with our own genome and compare the chimpanze...

Triple threat: World fin trade may harvest up to 73 million sharks per year

... floating around for a while, but we had no way of knowing whether or not this was accurate," says Ellen Pikitch, Ph.D., co-author and executive director of the University of Miami's Pew Institute for Ocean Science.

By knowing how polar bears respond to diminishing ice, resource managers and scientists will have the best chance of predicting where polar bears may continue to survive in a diminished ice environment and of adapting management strategies to reconcile the need...

UCLA neuroscience research leads to a possible treatment for type 1 diabetes

This month Diamyd Medical broke the code and announced that the GAD vaccine demonstrated statistically significant efficacy in preserving insulin production and that no serious adverse events associated with...

How did our ancestors' minds really work?

...res of the item (it was a tree, a stone, etc.), or knowing the spatial placement (left, right, middle, etc.). All animal species tested so far - from goldfish, pigeons and rats though to humans - seem to employ both strategies. However, if the type of recall task is designed so that the two strategies are in...

Impact of forest certification in developing countries examined

"Now that we have this ability, customers need to put their money where their mouths are and purchase certified produ...

NASA study solves ocean plant mystery

... and an important part of the ocean food chain. By knowing what limits its growth scientists can better understand how ecosystems respond to climate change. The study focused on phytoplankton in the tropical Pacific Ocean. It is an area of the ocean that plays a particularly important role in regulating at...

BGSU biologist trying to crack microscopic code

...ific proteins interact to support this shield, and knowing how they communicate would provide a key to disabling it, Larsen says. Once communication questions are answered, a goal is to develop drugs to break the barrier, rendering the bacteria more susceptible to the human body's natural defenses--antibod...

Blood clot fibers more elastic than spider's web

...ood clots. He said the company has an interest in knowing the properties of the fibers comprising a blood clot to determine how much force should be applied to break up clots. Researchers from Guthold's lab who worked on the project include Wenhua Liu, a physics graduate student at Wake Forest; and Eric S...

Sound investment: A new mathematical method provides a better way to analyze noise

...at tells us that we can know what the sound was by knowing when there was no sound." In other words, their pictures were being determined not by where there was volume, but where there was silence. "If you want to show that your analysis is a valid signal estimation method, you have to understand what a s...

Fibromyalgia increases pain and fatigue for pregnant women

...tting this condition properly diagnosed, let alone knowing where to turn for help once their condition is identified. We need to start looking at how FM affects all areas of these women's lives and come up with ways to provide as much comfort and support as possible," she said. Schaefer, whose research ...

Novel non-invasive imaging technology may allow precise diagnosis of coronary artery disease

...llion Americans may have ischemic episodes without knowing it. Myocardial perfusion (blood flow) imaging using single photon emission computed tomography (SPECT) is an established method for assessing the physiologic significance of coronary lesions in patients with chest pain, said Keidar. Computed tomogra...

RNA found in the cellular centrosome of surf clams

...RNA guides the translation of genes into proteins, knowing more about its role(s) in the centrosome may help researchers better understand the progression of diseases such as cancer, which has been linked to abnormal centrosome numbers in tumor cells," says Palazzo. The study on surf clam centrosomes was in...

FDG PET takes its place as a valuable tool in diagnosing fevers of unknown origin

...ght off infections, and treating the fever without knowing the cause may reduce the body's ability to deal with the possible infection. So patients undergo numerous tests to narrow down the possible causes, such as infections (tuberculosis, mononucleosis, HIV, pneumonia, meningitis), cancer (leukemia, Hodgki...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...ne unit--a so-called 'black-box' approach--without knowing which piece of DNA came from which organism," Eisen says. "But this black-box ecology just does not work well. To really understand the system, you've got to assign the different bits of DNA to organisms. This study shows why." For this particular in...

Discovery may speed forest biotechnology

...annual growth cycles and reproduction of trees. By knowing the genes that control these processes, it should be possible to genetically engineer trees that flower and reproduce more quickly. The long, slow growth of trees before they produce seed has been a major stumbling block towards the types of breeding...

UF scientists restore sight to chickens with blinding disease

...can't be done quickly. That's the hardest thing -- knowing there are people who need these treatments now. But we work as fast as we can. You'll see the first treatments for some of these genetic eye diseases soon, especially after the groundwork for an approved therapy is laid and the therapy works." ...

Prozac's target revealed

...stem cells into mature, specialized neurons. Next, knowing that Prozac treatment somehow increases the number of neurons in the brain, the researchers tested which step in the neurogenesis pathway might be stimulated by Prozac. They found that Prozac treatment specifically stimulates the generation of a kind...
