Men dont recognize their disease until a late stage
The rate of male breast cancer is on the rise and the disease in men is usually detected when the tumors are bigger, have spread and may be more aggressive, compared to diagnosis of the disease in women, concludes the largest study ever conducted of male breast cancer.
The findings, published today in the online edition CANCER and will appear in the July 1 print issue of the publication, suggest both that breast cancer in men may have some important biological differences from the female disease, and that men are seemingly less aware than they should be that they can develop breast cancer.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
