Newborns have ear preferences, too
...after infants are at least four month old. So two scientists
who screened thousands of newborns as part of a project to optimize infant hearing tests were startled when they realized their data show that infants do have stimulus-related ear differences from birth. "We don't think that these differences are an...
Researchers discover why mutant gene causes colon cancer
...d, colon cancer can result. "For a long time, scientists
believed they knew what the APC gene did that it regulated cell growth and division but now we know we've been missing a big piece of the picture," reports David Jones, Ph.D., principal investigator of the study and leader of HCI's Colon Cancer Sci...

...tion. Spectral imaging is unique because it allows scientists
to take images taken at specific wavelengths. Crucially, wavelengths between 580nm and 600nm reveal the oxygenation state of the blood vessels in the eye, telling doctors which areas are healthy and which might be diseased. Dr. Andrew Harvey, one of...

Do genes respond to global warming?
...d population dynamics are increasingly understood, scientists
know little about how species respond to climate change at the genetic level. Now it appears that climate change can shape genetic diversity. Elizabeth Hadly and colleagues have analyzed three different dynamic processes--environmental change, popula...

Broken arms and collateral damage: clues to predator-driven evolution
ANN ARBOR, Mich.---Ever since Darwin's day, scientists
