- 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.

- Fantastic Voyage: A New Nanoscale View Of The Biological World
10-06-2006 · ScienceDaily
Echoing the journey through the human body in "Fantastic Voyage," doctors might soon be able to track individual donor cells after a transplant, or to find where and how much of a cancer treatment drug there is within a cell. New technology described in a study published in the open access journal, Journal of Biology makes it possible to image and quantify molecules within individual mammalian or bacterial cells.

- Colorful view for first land animals
10-24-2007 · EurekAlert!
When prehistoric fish made their first forays onto land, what did they see? According to a study published in BMC Evolutionary Biology, it's likely that creatures venturing out of the depths viewed their new environment in full color.

- Radar opens new window into the ice for Antarctic scientists
10-16-2006 · EurekAlert!
Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS). Getting a clearer view of how ice behaves is important because it will help scientists predict more accurately how the ice sheet will respond to future climate change. The results are published this week in the Journal of Glaciology.

- Studies force new view on biology of flavonoids
03-05-2007 · EurekAlert!
Flavonoids, a group of compounds found in fruits and vegetables that had been thought to be nutritionally important for their antioxidant activity, actually have little or no value in that role. However, these same compounds may indeed benefit human health, but for reasons that are quite different - the body sees them as foreign compounds, researchers say, and through different mechanisms, they could play a role in preventing cancer or heart disease.

- Peering into the shadow world of RNA
12-04-2006 · EurekAlert!
The popular view is that DNA and genes control everything of importance in biology. The genome rules all of life, it is thought. Increasingly, however, scientists are realizing that among the diverse forms of RNA, a kind of mirror molecule derived from DNA, many interact with each other and with genes directly to manage the genome from behind the scenes.

- Physicists wipe away complexity for a clearer view of heavy nuclei
03-14-2007 · EurekAlert!
In a March 16 Physical Review Letters article, researchers from Michigan State and Central Michigan universities report dramatic success in slashing computational time associated with standard nuclear theory calculations from days or weeks to minutes or hours. Their work, which draws heavily on quantum chemistry, may help address one of the most important questions in nuclear physics today: what is the structure of heavy atomic nuclei?

- Does natural selection drive the evolution of cancer?
11-17-2006 · EurekAlert!
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. Insights from their work may have profound implications for understanding why current cancer therapies often fail and how radically new therapies might be devised.
