Birth Control Pill for Men? Scientists Find a Hormonal on-and-Off Switch for Male Fertility
30/11/2009
ScienceDaily
A new research report published in the December 2009 print issue of The FASEB Journal could one day give men similar type of control over their fertility that women have had since the 1960s. That's because scientists have found how and where androgenic hormones work in the testis to control normal sperm production and male fertility. This opens a promising avenue for the development of "the pill" for men.

Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be "building" their own host galaxy. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars.

Spiral Galaxies: Exploring the Baffling Boxy Bulge
23/11/2009
ScienceDaily
When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges are more easily distinguishable from the disc. This exceptionally detailed edge-on view of NGC 4710 taken by the Advanced Camera for Surveys (ACS) aboard Hubble reveals the galaxy's bulge in the brightly coloured centre. The luminous, elongated white plane that runs through the bulge is the galaxy disc. The disc and bulge are surrounded by eerie-looking dust lanes.
