New York and North Carolina scientists report the assembly of the first functioning prototype of an artificial Golgi organelle. The lab-on-a-chip device could lead to a faster and safer method for producing heparin, the widely used anticoagulant/blood thinner.
Robert Linhardt and colleagues point out in a recent study that the Golgi bodies are one of the most poorly understood organelles of the human body. Scientists already know, however, that the organelles play a key role in producing heparin.

Derek Lovley and his minions at the University of Massachusetts Amherst are playing around with Geobacter, and observed the evolution of a new strain. This new strain dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than earlier strains, cutting the time to reach electricity-producing concentrations on the electrode.

Researchers at Stanford University School of Medicine say that current diagnostic tests for ovarian cancer are ineffective for early detection. A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter.

Scientists reported the successful isolation of genetically diverse Marburg viruses from a common species of African fruit bat. The Marburg virus is a genetic cousin to the Ebola virus, and can produce severe fever, bleeding, and up to a 90% death rate during outbreaks. The African fruit bat is also known as the Egyptian fruit bat, Rousettus aegyptiacus. This is the first time the virus has been isolated from a natural host.

Armchair astronomers helped discover a batch of tiny galaxies that may help professional astronomers understand how galaxies formed stars in the early universe.
"Green Pea" galaxies are forming stars 10 times faster than the Milky Way, despite being 10 times smaller and 100 times less massive, making them among the most extremely active star-forming galaxies ever found. They are between 1.5 billion and 5 billion light years away.
