For every man who thinks women are complex, theres new evidence theyre correct; at least when it comes to their genes.
Chromosomes contain the set of instructions to create an organism. Men have one X chromosome and one Y chromosome, the latter being responsible for the characteristics that make men male, including the male sexual organs and the ability to produce sperm. In contrast, women have two copies of the X chromosome. But, because the X chromosome carries a bigger instruction manual than the Y chromosome, biologys solution is to largely inactivate one X chromosome in females, giving one functional copy of the X in both men and women.
"Our study shows that the inactive X in women is not as silent as we thought," said Laura Carrel, Ph.D., assistant professor of biochemistry and molecular biology, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center. "The effects of these genes from the inactive X chromosome could explain some of the differences between men and women that arent attributable to sex hormones."

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
