The Editorial says: “Far from its historic portrayal as a silent killer, ovarian cancer is preceded by symptoms, as recent evidence shows. Women who are ultimately diagnosed with the disease, and usually at a late stage, say that they did have symptoms, primarily gastrointestinal or urinary, for three to four months on average before diagnosis.”
Because of these delays in diagnosis, patient groups have pressed for education about early symptoms among women and doctors. Several US organisations have released a consensus statement, urging women to seek medical attention if they have new and persistent symptoms of bloating, pelvic or abdominal pain, difficulty eating or early satiety, and urinary urgency or frequency.
The Editorial accepts that such symptoms can be vague and related to other conditions, but adds that anything which leads to greater awareness of ovarian cancer is commendable. It says: “On the other hand, the [consensus] statement provides no specific guidance about what to do when such women present to them; the need for the challenging art of clinical judgement remains acute.”
It adds: “There is no evidence whatever that detection based on these factors will substantially shift diagnosis early enough to affect mortality.”
Despite its considerable limitations, the Editorial supports the consensus statement. It concludes: “The statement is a move in the right direction. Its chief contribution might be to improve communication between women and their doctors. To maximise its chance of success, it ought to be combined with other efforts, especially increased funding for ovarian cancer research, which has been declining for the past several years; large prospective trials of early detection methods; ongoing education and awareness campaigns for the public and professionals; and development of standardised diagnostic algorithms for the disease.”

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.
