Transparent fish to make human biology clearer
02-06-2008 · EurekAlert!Zebrafish are genetically similar to humans and good models for human diseases. Now, researchers in Children's Hospital Boston's Stem Cell Program have bred a zebrafish that is transparent throughout its life, allowing researchers to directly view its internal organs and observe disease processes like tumor growth or engraftment of bone-marrow transplants in a living organism.

- Mice, men make livers differently
05-21-2007 · EurekAlert!
Scientists often study mice as a model for human biology and disease, because their basic biological processes are assumed to be essentially the same as those of humans. But now, a team of MIT researchers has uncovered a surprising difference. In a study of gene regulation in mouse and human liver cells, they found that master regulatory proteins function in very different ways in mice and humans.

- Transparent zebrafish help researchers track breast cancer
10-22-2007 · EurekAlert!
What if doctors could peer through a patient's skin and see a cancer tumor growing? They'd be able to study how tumor cells migrate: how they look, how they interact with the blood system to find nourishment to grow and spread through the body. Scientists at the UCSD School of Medicine can't look through human skin. But a small, tropical minnow fish common to aquariums has given researchers a window for viewing live, human cancer cells in action.

- Unraveling where chimp and human brains diverge
11-13-2006 · EurekAlert!
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species. Now UCLA scientists have identified a new way to pinpoint the genes that separate us from our closest living relative -- and make us uniquely human.

- Forsyth scientists make major discovery to advance regenerative medicine
02-28-2007 · EurekAlert!
Scientists at Forsyth may have moved one step closer to regenerating human spinal cord tissue by artificially inducing a frog tadpole to re-grow its tail at a stage in its development when it is normally impossible. Using a variety of methods including a kind of gene therapy, the scientists altered the electrical properties of cells thus inducing regeneration. This discovery may provide clues about how bioelectricity can be used to help humans regenerate.

- Latest IPCC report highlights need for integrated climate/human behavior models
04-06-2007 · EurekAlert!
How can humans adapt to climate change without adding even more stress to the environment? Scientists are now looking at ways to integrate the human dimension of climate change -- the choices we need to make to adapt to a changing global climate -- with the sophisticated climate prediction models used for the IPCC Assessment Reports. The goal: To evaluate the best ways forward.

- Gene mutation linked to increased athletic performance in whippets
05-04-2007 · EurekAlert!
Whippets are bred for speed and have been clocked at speeds approaching 40 miles per hour. Scientists at the National Human Genome Research Institute have now discovered a genetic mutation that helps to explain why some whippets run even faster than others. Published in the open-access journal PLoS Genetics, their findings will make for a fascinating experiment in applied genetics.
