New technique targets pesticide-resistant insects
...that have evolved resistance to pesticides used in many
agricultural industries, including horticulture and field crops. Results of the research including details of scientific trials conducted in Australia, Spain and South Africa, are being presented today (Friday October 8) at the 2nd European Whitefly ...
Study describes basic mechanism in cell growth control involving damaged DNA
...l. "Inevitably, the molecular pathways controlling many
cellular processes such as DNA repair must interact with those regulating cell division," said Dr. Yue Xiong, professor of biochemistry and biophysics at UNC. "An alteration in this critical interaction may be the cause of human cancer, which is char...

Why do African-American women have more pregnancy problems?
... white women to die during pregnancy, and twice as many
black babies as white babies die in infancy. Yet researchers know little about why pregnancy and infant health differ by race, despite massive efforts to address this persistent problem. Now, researchers at the University of Michigan will examine the...

of the genes expressed in B cells have been activated and the genes that encode antibodies have begun the process of recombination. Finally, EBF and E2A activate a regulator called Pax-5, which pushes the specified pro-B cell to stage 4, a committed ...
