Definitive evidence found of a swimming dinosaur

...birds." The question of whether dinosaurs could swim has been researched for years. Until now, however, very little hard evidence existed documenting the behavior. Several earlier discoveries were later found to have been produced on dry ground or categorized as ghost traces, possible undertracks prese...

Bones in motion: Brown scientists to create new 3-D X-ray system

...ch their bones move in 3-D as they run, fly, jump, swim and slither. This high-resolution, high-speed imaging system will contribute to better treatments for knee, shoulder, wrist and back injuries and help scientists understand the evolution of complex movements, from the flight of birds to the leap o...

Mutation improves memory, may lead to memory-enhancing pill

...aze test. In the test, the mice were trained to swim to a hidden platform. After several days of training, the altered mice were able to find the platform significantly faster than normal mice could, they reported. "For example, if a person were reading a page of a textbook, it might take several ti...

Tracking sperm whales and jumbo squid

...is using energy all of the time, because it has to swim to breathe. So when it gets into really warm water, I think it gets out pretty quickly. These deep dives, therefore, may have some kind of recovery function. We think the stress may be temperature-related, but another factor could be oxygen. It’s pos...

Rapid, Low-Cost DNA Testing

...fy criminals, test ponds and pools before children swim in them, and identify harmful genetic sequences in medical research, to name only a few applications. Rothberg's innovative procedure quickly and inexpensively identifies genetic sequences in any sample of DNA. he technology is a novel fluorescent D...

Shedding new light on proteorhodopsin

...ls when their respiration was impaired, they would swim or stop depending on the light's color," said Walter. "Proteorhodopsin has an absorption spectrum that peaks in the green wavelengths, so the cells swam when they were exposed to green light, but stopped when they were exposed to red light." In t...

Baby fish 'smell their way home'

...es then choose currents that smell like 'home' and swim up them. The ones that cannot do this perish. The ones that get home preserve the unique 'ethnic' make-up of their tribe ?and so continue the process of evolving into separate new species." How the fish learn the unique smell of home is a myster...

New insights into autoimmunity and depression

...tests to gauge motor function; a staircase test; a swim T-maze test to assess cognitive function; and a passive avoidance test to measure the ability of mice to remember a foot shock delivered 24-hours earlier. Depression-like behavior was strongly observed in the performance of anti-ribosomal P anti...

Renewed dolphin slaughter prompts new campaign

"The Japanese dolphin drive hunts are an abominable violation of any standard of animal welfare, and these hunts inflict measurable pain and suffering on an...

Researchers reveal mystery of bacterial magnetism

...e to oxygen when in a magnetic field, so that they swim away from oxygen at much lower concentrations." It is as if the climber gets tired and turns around sooner when heading up the mountain, keeping her from heading too far in the wrong direction. And the stronger the magnetic field, the bigger the ef...

Female guppies risk their lives to avoid too much male attention

...rinidad, the researchers found that female guppies swim in habitats that contain few males ?but many predators. "Male guppies spend most of their time displaying to females. But if their courtship displays don't impress the females, males will attempt to sneak mating with them when they aren't looking," ...

Even fish don't swim well when they're young!

... way; it appears thicker, like syrup and harder to swim in. "Momentum can explain some of the poor swimming in larvae, but not all, and the difference in coasting ability cannot be explained by differences in body length either", Müller argues. Hopefully Müller's findings about pectoral fins and swimbla...

Vital ocean prey play active role in environment

...yos hatch into free-swimming larvae at depth, then swim upward over the course of several weeks. The larvae are at this stage dependent on microorganisms found on the underside of sea ice for food, and as they grow they drift with pack ice. After they metamorphose in late winter and early spring, the juve...

UF scientists trace origin of shark's electric sense

...'s magnetic field for navigation, enabling them to swim in precise paths across large expanses of featureless ocean, Cohn said. "If you think of this in the big picture of evolution of sensory systems, such as olfaction, hearing, vision and touch, this shows sharks took a pre-existing genetic program and...
