Chemicals that mimic the body’s natural hormone oestrogen are known to affect a woman’s risk of breast cancer. Evidence is mounting that the aluminium-based compound, which often makes up quarter of the volume of some antiperspirant agents, can break through the skin and that once in the body it could mimic oestrogen. A review just published in the Journal of Applied Toxicology calls for further research to evaluate the potential that this could increase the risk of getting breast cancer.
Over recent years scientists have found that many compounds in the environment mimic or interfere with oestrogen. These compounds are normally complex molecules and are found in many plants, and used in materials like detergents, pesticides and plastics. Now scientists are realising that a variety of simple metal ions, including aluminium and cadmium can also bind to the body’s oestrogen-receptors and influence their action.
“Since oestrogen is known to be involved in the development and progression of human breast cancer, any components of the environment that have oestrogenic activity and which can enter the human breast could theoretically influence a woman’s risk of breast cancer,” says author of the review Dr Philippa Darbre, who works in the School of Biological Sciences, at the University of Reading, UK.

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.
