In honor of the bicentennial of Charles Darwin's birthday on February 12, 2009, Mike White at Adaptive Complexity decided to engage in a massive undertaking; 30 days of science in Show Me The Science month.     Nothing new, you might think, because we do science 365 days a year and some people who are just bloggers post 5 things every day.
An unusual spiral galaxy in the Coma galaxy cluster has been imaged using data obtained by the Advanced Camera for Surveys on the Hubble Space Telescope. It reveals fine details of the galaxy, NGC 4921, and an extraordinary rich background of more remote galaxies stretching back to the early Universe.
 
The Coma galaxy cluster, in the northern constellation of Coma Berenices, the hair of Queen Berenice, is one of the closest, very rich collections of galaxies in the nearby Universe. The cluster, also known as Abell 1656, is about 320 million light-years from Earth and contains more than 1000 members. The brightest galaxies, including NGC 4921 shown here, were discovered back in the late 18th century by William Herschel. 
One testament to the pervasive nature of evolution is that so many varied groups, even ones in opposition to each other, found an endorsement in his work.    Proponents of eugenics, slavery and even Hitler could rationalize their views saying it was just evoluti0n while abolitionists saw just the opposite.
The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell shows for the first time that neural stem cells taken from adult mice can take on the characteristics of embryonic stem cells with the addition of a single transcription factor. Transcription factors are genes that control the activity of other genes.
Laboratory work in animals showed limited activity when statins were given to prevent breast cancer, according to a report in the February issue of Cancer Prevention Research, a journal of the American Association for Cancer Research. 

Statins, sold under brand names like Lipitor and Zocor, are primarily given to lower cholesterol and prevent heart disease, and prominent cardiologists almost universally agree that their use has changed the landscape. 

The use of these drugs in cancer prevention has been more controversial. Results of epidemiology studies, which rely on looking backward rather than forward and thus are subject to confounding factors, have yielded mixed results when examining breast cancer. 
Emergence of black-colored wolves is the direct result of humans raising dogs as pets and beasts of burden, according to new research by a University of Calgary biologist in Science. The dark coloring may also aid the survival of the species as wolf habitat is affected by climate change in the future, the study suggests.
