Transgenics sped up

A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity.

T-cell exhaustion

A new study of immune cells battling a chronic viral infection shows that the cells, called T cells, become exhausted by the fight in specific ways, undergoing profound changes that make them progressively less effective over time.

Sex hormone signature indicates gender rather than just chromosomes

Help with assigning gender could one day be at hand for intersex individuals whose genital phenotypes and sex chromosomes don't match, thanks to the discovery of a stable sex hormone signature in our cells.

Massive microRNA scan uncovers leads to treating muscle degeneration

Researchers have discovered the first microRNAs - tiny bits of code that regulate gene activity - linked to each of 10 major degenerative muscular disorders, opening doors to new treatments and a better biological understanding of these debilitating, poorly understood, often untreatable diseases.
