London, United Kingdom. New findings argue for the persistence of sex-linked chromosomes, such as the male Y chromosome, refuting theories that the Y is doomed to extinction.
The results confirm that although these chromosomes have shrunk over millions of years, and have lost many of their original genes, those that remain are extremely important in predicting fertility and are, therefore, unlikely to become extinct.

What I was walling in or walling out,
Robert Frost, Mending Wall
Waltham, MA, USA. In rural New England, as in much of the rest of the world, people mark their territory, like some race of architecturally-adept spaniels, by building a wall around its borders.

 TS-Si News Service Friday, 11 May 2012 Boulder, CO, USA. A new prototype bioreactor a device for culturing cells to create engineered tissues evaluates the engineered tissue during its creation.
The bioreactor both stimulates and evaluates tissue as it grows, mimicking natural processes while eliminating the need to stop periodically to cut up samples for analysis.

 TS-Si News Service Wednesday, 09 May 2012 Washington, DC, USA. A study in Social Studies of Science shows that males win scientific awards more than 95% of the time when men chair committees that select the recipients.
In the past two decades women have begun to win more awards, compared to men, but they win more service and teaching awards and fewer of the prestigious scholarly awards than would be expected based on their representation in the nomination pool.

 TS-Si News Service Tuesday, 08 May 2012 London, UK. An animal model has been used to better understand the clinical significance of chronic psychotropic drug treatment on structural remodeling of the brain.
The effects of these structural changes has been unclear given the many challenges in executing longitudinal, controlled, and randomized studies to evaluate this issue in humans.

 TS-Si News Service Sunday, 29 April 2012 Atlanta, GA, USA. Compressed sensing has provided super-resolution plus faster temporal resolution, resulting in a clear picture of a single cellular structure in motion.
Despite many achievements in the field of super-resolution microscopy in the past few years with spatial resolution advances, live-cell imaging has been challenging because of the need for high temporal resolution.

 TS-Si News Service Friday, 27 April 2012 Oslo, Norway. Our most remote relative lives down in the sludge bottom of a little lake south of Oslo in Norway and represents a previously unknown branch of the tree of life.
Biologists worldwide have eagerly awaited the results of the genetic analysis of a very rare micro-organism, one of the world's smallest known species (hereafter called the protozoan) that may provide insights into what life looked like on earth almost one thousand million years ago.

 TS-Si News Service Friday, 27 April 2012 New York, NY, USA. New mechanisms that control protein expression in different regions of embryos shed additional insight into how physical traits are arranged in body plans.
The findings, which appear in the journal Cell, call for reconsideration of morphogen theory, which posits that proteins controlling traits are arranged as gradients, with different amounts of proteins activating genes to create specified physical features.

 Maggie Clark (Stateline) Thursday, 26 April 2012 Paducah, KY, USA. The need for more information about prescription drug abuse is beyond dispute, but deciding who should have access to such information is a divisive issue.
Dr. Shawn Jones, an ear, nose and throat surgeon in Paducah, Kentucky, was conducting a routine office appointment when he got a phone call from a worried pharmacist. The pharmacist had just received a prescription from Jones for 90 Percocet pain pills, an unusually large order for a doctor who rarely prescribes more than 2

 TS-Si News Service Wednesday, 25 April 2012 New York, NY, USA. Ninety percent of every mammal's genome is dark matter harboring ancient viral DNA that infected our ancestors from as far back as the age of the dinosaurs.
Scientists have uncovered clues as to how our genomes became riddled with viruses, revealing important new information.
