Common prostate cancer therapy disrupts brains hippocampal memory system
Oregon Health & Science University researchers studying how testosterone deprivation affects verbal memory found that men undergoing the prostate cancer therapy forget things faster than their healthy counterparts. Scientists in the OHSU School of Medicines departments of Behavioral Neuroscience and Medicine, and the OHSU Cancer Institute, in a study presented Sunday to the Society for Neuroscience in San Diego, found that word retention drops sharply after only two minutes among men undergoing testosterone deprivation therapy.
However, initial learning of the words, or encoding, was the same for testosterone-deprived and healthy men, according to the study titled "Androgen ablation impairs hippocampal-dependent verbal memory processes." Men who have undergone testosterone deprivation "are able to encode these words well, and if I ask them immediately, they can recall them as easily as non-hormone-deprived men," said Joseph Bussiere, a graduate student in behavioral neuroscience and the studys lead author. "But after only two minutes, theres a marked drop-off. When you stretch the time between encoding and retrieval, thats where the problem lies."

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
