Mayo Clinic researchers have found that surgical removal of both ovaries doubles a womans risk of developing Parkinsons disease and parkinsonism many years later in life. They also discovered that the younger a woman is at the time of the surgery, the higher her risk.
"The risk is higher for women with both ovaries removed; however, it may also be somewhat increased when only one ovary is removed," says Walter Rocca, M.D., Mayo Clinic epidemiologist and lead study investigator. "In addition, there is a suggestion that for women with one ovary removed, removal of the uterus may also increase the risk."
Dr. Rocca emphasizes that his studys findings must be viewed by women contemplating an elective or preventive removal of the ovaries and uterus in consultation with their physicians in the context of a womans medical history, her genetic makeup and other diseases or risk factors. He also stresses that physicians must carefully consider the age of the woman at the time of the surgery and the option of treating the woman after surgery with estrogen therapy.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
