From:
feeds.sciencedaily.com
Sparrows, blackbirds and the great tit are all birds known to sing at a higher pitch in urban environments. It was previously believed that these birds sang at higher frequencies in order to escape the lower frequencies noises of the urban environment. Now, researchers have discovered that besides noise, the physical structure of cities also plays a role in altering the birds' songs. Read more »

From:
feeds.sciencedaily.com
Oncologists have known that in order for cancer cells to spread, they must transform themselves so they can detach from a tumor and spread to a distant organ. Now, scientists have revealed critical steps in what happens next -- how these cells reverse the process, morphing back into classical cancer that can now grow into a new tumor. Read more »

If you are looking for a particular object -- say a yellow pencil -- on a cluttered desk, how does your brain work to visually locate it? For the first time, neuroscientists have identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and will guide future research into visual and attention deficit disorders. Read more »
