Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

...an approach animals in the wild more easily from a car than by foot may be due to an innate "life detector" tuned to the visual movements of an approaching predator's feet, says Queen's University psychologist Niko Troje. "We believe this visual filter is used to signal the presence of animals that are...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

Traditionally, DNA sequences are thought to have to look similar to function similarly; this is how scientists identify genes in other species, a strategy best used for studying similar species.

Infants can organise visual information at just four months

...al grouping experiments, each baby was placed in a car seat facing a screen onto which images were projected. Overhead cameras recorded how long each infant looked at images on the screen. The infants were shown an array where the stimuli were arranged by similarity in either horizontal lines or vertical...

Researchers find how some antibiotics kill bacteria

...ark plugs from an engine," Artsimovitch said. "The car may look fine, but it won't run. "Until we could look under polymerase's molecular 'hood' we couldn't see what the problem was," she said. "We never suspected that removing this ion was what killed rifamycin-sensitive bacteria. But the resolution of...

Energy management in cells may hold key to cancer defense

...xplains Witters, who likens a low-energy cell to a car with no gas in its tank. "In a previous study, we found that the cellular "gas gauge," AMPK, can turn around and alter any deficits in the cell if it is turned on by the kinase LKB1. In this JBC study, we wanted to see if AMPK could also be turned ...

This discovery points to the fact that our early experiences influence how we solve such problems and could mean that by varying the environments that we encounter early in life, we could bro...

Agilent Technologies introduces advanced zebrafish, mouse microarrays for stem cell and developmental biology research

Which is more likely to happen - you being in a car wreck or being bitten by a shark? Those who answered that cars are greater killers win a free trip to the beach. It's really no contest, says a Texas A&M University professor. Your chances of being in a wreck are far greater than being a shark's...

Traidl-Hoffmann and colleagues showed that extracts from birch pollen and other common allergens block the production of a soluble protein by immune cells that normally inhibits allergic reactions. They went on to identify the com...
