MUHC investigators search for the root of sexual pain in women

...Dr. Binik. "A better understanding of the specific features of both vaginismus and dyspareunia will undoubtedly lead to more appropriate and effective treatments." Patients who wish to be involved in this study, or wish to learn more about sexual pain in women should contact: ...

Fossil find: 'Godzilla' crocodile had head of a dinosaur, fins like a fish

...But that's not all that made it unusual. Two other features ?its hefty size and T. rex-like snout ?have earned...hat were around at the same time had very delicate features ?long, skinny snouts and needle-like teeth for catching small fish and mollusks,?he said. “But this ...

Many needles, many haystacks

...r motifs are so small that it is hard to tell what features allow them to bind to other molecules. Now Victor Neduva, a PhD student in Russell's group, has developed a method to scan molecules and tease out new linear motifs. "If two or more different proteins share a binding partner, there is often a common...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

...to an odor, but you can still detect its signature features minutes afterwards," said Galán. A future question that could be addressed using this research is addressing how short-term memory gets encoded as long-term memory over time, said Galán. ...

Brain activity related to processing faces is similar in people with, without autism

...lated the amount of time autistic people looked at features of a face with activation of the amygdala, the "anxiety center" of the brain. They propose that the use of behavioral interventions aimed, perhaps, at de-sensitizing autistic individuals to the anxiety triggered by looking at faces may help to impro...

Did feathered dinosaurs exist?

...attempt to define morphologically the most salient features of Aves: "Birds are mesotarsal bipedal archosaurs with pennaceous feathers, and a tridactyl avian hand composed of digits 2-3-4." It is too early to abandon debate on the origin of birds, the authors say. However, mounting evidence suggests that "a...

Deep treasure to be found in Oculina Bank

...h offers unprecedented resolution to reveal bottom features that were previously indistinguishable. The team w...ientists to associate certain colors and other map features with the type of habitat they indicate, such as sand bottom, coral ledges, or coral rubble, allowing...

DNA self-assembly used to mass-produce patterned nanostructures

... one ten-millionth of a meter square. The smallest features on these square DNA lattices are approximately five to 10 billionths of a meter (nanometers), according to the scientists, compared with about 65 nanometers in silicon circuits created using photolithography. To demonstrate their ability to mass-pro...

Dangerous tricksters: Some bacterie use immune cells to reproduce

...Bonn researchers is to investigate which bacterial features are important for preventing the merger of phagosomes and lysosomes, and how the immune system normally successfully eradicates an infection despite all the tricks the bacteria use. Rhodococci, incidentally, can also cause diseases resembling TB in ...

NRL scientists detect 'milky sea' phenomena

...tions cannot be fully explained based on the known features of any light-emitting organism, these so-called "milky seas" are hypothesized to be manifestations of strong bioluminescence produced by colonies of bacteria associated with a microalgal bloom in the surface waters. Because of the lack of scientific ...

The Antarctic Ocean floor

...f photographs are again taken in order to identify features peculiar tot he animal and, finally, the classification of the species in question is presented in the specialist literature. In the previous campaign, expedition members discovered a new species of vermes. The name of the species and its morphologi...

Study Holds Promise For New Way To Fight HIV

...n our shores. The team tested for DNA and skeletal features to prove that the giant deer - which roamed across Europe and Siberia with prehistoric man and is the subject of numerous cave drawings - has its DNA in common with the fallow deer, one of the most widespread deer in the UK since their introduction b...

Extinct giant deer's descendant found in UK

The earliest animals had human-like genes

... look at living organisms that have preserved many features of their ancestors. Detlev Arendt's group is doing this with a small marine worm called Platynereis dumerlii. "Similar animals are already found in the earliest fossils from the Cambrium, about 600 million years ago," Arendt explains, "arguing that P...

Biotechnology's newest chemical tool

...ed to its joint flexing for autonomous control. It features that miracle of evolution, the opposable thumb, so the device can perform different grasping actions. Taking inspiration from the real hand, where a muscle pulls a tendon inside a synovial sheath, CYBERHAND's finger cables run through a Teflon shea...

Researcher uncovers details of how cancer spreads

...lity to transform a normal cell into one with many features resembling those found in cancer cells. While this virus has not been found in humans, it does lead to tumor growth in chickens and created cancerous cells in the cultured system. In the study, the researchers found that v-Src attaches to an enzyme, ...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

...ory. "This simple theory explains many unresolved features of the current genetic code. No one has ever been able to do this before, so we are very excited." The theory also explains how the structure of the genetic code maximises error tolerance. For instance, 'slippage' in the translation process tends to...

Grasshopper love songs give insight into sensory tuning

... the receptors particularly matched characteristic features of species-specific acoustic communication signals used by grasshoppers to attract mating partners. "Hence, instead of maximizing the average information gained about natural stimuli, the receptors appear to maximize the information gained about spe...
