Children Become Gorillas In VR Zoo

...ack male gorilla, the Zoo Atlantaresearchers could tell us the range and probabilities of thesilverback's actual responses." Zoo researchers are impressed with the final outcome, which wasn'teasy to achieve. Unlike monkeys, apes are not extremely active animals,and much of their social interaction is sub...

Hawaiian Whales Show 'No Overt Response' To Sounds Of ATOC Simulation

..."ATOC is an important international study that can tell whether global climate conditions are changing, not only for those of us on the surface but for organisms in the oceans. Any noted changes in the ocean ecosystem could mean change on the surface ecosystem. It's definitely worth doing and I hope ...

New Ultrasensitive Technique For Accurately Characterizing Biomolecules Is Developed By Cornell Chemists

... so we not only can analyze the sample, but we can tell what it is. With mass spectrometry, we can characterize and identify." The technique may be useful for examining a host of human medical disorders, the researchers said. "This is an excellent tool for looking at an isolated biological system at the ...

Human-Like Ability, Categorical Perception, Found In Insects

...seful ability in some situations is our ability to tell the difference between sounds like 'ba' and 'pa,' " Wyttenbach noted. "Even though there is a continuum of variation between 'ba' and 'pa' based on voice onset time or VOT, which instruments can detect, our ears don't discriminate. We hear either '...

New Software Provides Quick Analysis of ion-Channel Activity

...e world's ports and estuaries. It is too early to tell what the impact of this introduction will be on the ecosystem, Sloan says, but at the population levels currently found, it is likely to have a large impact on the native species of foraminifer. The introduction of exotic species to the estuaries an...

Researchers Develop Model Using Birds As Indicator Of Wetlands Health

Based on recent measurements of apomyoglobin, Gruebele has identified twodistinct phases in the folding process. In the first phase, which lastsseveral...

Scientists Identify Gene For Sexual Behavior In Male Flies

...ns in the fru gene become bisexual -- they cannot tell other males fromfemale flies when courting. With this research, the team of geneticistscloned and isolated the fru gene, and showed that it controlsmuch more than the male's choice of partners. They showed that the fru gene is: A master gene t...

Birds Deal With "Cocktail Party Effect"

External signals tell the developing cells what kind of cell to becomeby initiating a cascade of internal molecular reactions called the "signaltransduction pathway." "Cancer can result if errors occur inthe signal-transduction pathway, giving a cell the signal to divide ...
