- Does Missing Gene Point To Nocturnal Existence For Early Mammals?
10-13-2006 · ScienceDaily
A gene that makes cells in the eye receptive to light is missing in humans, researchers have discovered. They say that whereas some animals like birds, fish and amphibians have two versions of this photoreceptor, mammals, including humans, only have one.

- Clock gene plays role in weight gain, study finds
05-17-2007 · EurekAlert!
Scientists have discovered that a gene that participates in the regulation of the body's biological rhythms may also be a major control in regulating metabolism. Their finding shows that mice lacking the gene Nocturnin, which is regulated by the circadian clock in the organs and tissues of mammals, are resistant to weight gain when put on a high fat diet and also are resistant to the accumulation of fat in the liver.

- Simple diagnostic test detects genetic signs of lung cancer in a patient's sputum
01-18-2007 · EurekAlert!
DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

- Burrowing mammals dig for a living, but how do they do that?
10-28-2007 · EurekAlert!
Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. When seen in the lab, they are nothing like the long upper arm bones of any other mammal, says Samantha Hopkins, a paleontologist at the University of Oregon.

- Mechanism for the in-vivo transport of siRNA
09-17-2007 · EurekAlert!
RNA interference, a natural mechanism that inhibits the gene expression of individual genes in eukaryotic cells, is a major topic in modern biology. However, their potential was usable to only a limited extent in mammals because the mechanism for the uptake of small RNAs was unknown up to now. ETH Zurich biologists have now clarified this, which also opens the door for therapies based on this mechanism.

- Study led by Scripps Research scientist reveals little-known cell networks vital to circadian rhythm
05-03-2007 · EurekAlert!
In a wide-ranging systems biology study of circadian rhythm, a multi-institutional collaboration led by Scripps Research Institute Professor Steve Kay has uncovered some little-known cellular mechanisms for sustaining circadian rhythm and limiting the impact of genetic clock mutations in mammals. The new findings could have important implications for future circadian studies, and point researchers toward new ways to manipulate human circadian rhythm at the molecular level to treat diseases such as bipolar disorder.

- 'Jumping genes' could make for safer gene delivery system
09-26-2007 · EurekAlert!
To move a gene from point A to point B, scientists and gene therapists have two proven options: a virus, which can effectively ferry genes of interest into cells, and a plasmid, an engineered loop of DNA that can do the same thing, albeit usually only on a short-term basis.

- Researchers studying how singing bats communicate
10-18-2007 · EurekAlert!
Bats are the most vocal mammals other than humans, and understanding how they communicate during their nocturnal outings could lead to better treatments for human speech disorders, say researchers at Texas A&M University.
