Sexual Assault Awareness Month (SAAM).

Sexual Assault Awareness Month. The goal of SAAM is to raise public awareness about sexual violence and to educate communities and individuals on how to prevent sexual violence.

National Sexual Violence Resource Center serves as the comprehensive resource center on sexual violence and its prevention, and sponsors SAAM each April.
Please donate to the Maetreum of Cybele.

The Maetreum of Cybele needs your help in their fight for religious freedom.



is dedicated to the acceptance, medical
treatment, and legal
protection of individuals correcting the misalignment
of their brains and their anatomical sex, while supporting their transition
into society as hormonally reconstituted and surgically corrected citizens.

A man and his chickens.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.

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.

radial microtubule organizing center (rMTOC).Leicester, UK. Scientists observing the architecture within a cell have seen for the first time how it changes during gamete (sex cell) formation to complete the process.

The investigators expect that the information obtained researching yeast cells will bring novel insights into the basic mechanisms of cellular regulation, which may be applicable to higher organisms including humans.

Evolution.Sheffield, England. Evidence shows humans continue to evolve and that significant natural and sexual selection is still taking place in our species throughout the world.

Despite advancements in medicine and technology that many people believe can alter the human trajectory, as well as an increased prevalence of monogamy, research reveals humans are continuing their evolution just like other species.

Super-resolution microscopy.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.
