Researchers at the Technion-Israel Institute of Technology have developed three drugs to remove excess iron from the brains of patients with neurodegenerative diseases. The presence of too much iron in the brain is a hallmark of such diseases. The drugs, VK-28, HLA-20 and M30, mop up the iron before it can trigger a "brain rust" chemical reaction where highly active oxygen particles destroy brain cells.
Professor Moussa Youdim of the Faculty of Medicine and his colleagues – Prof. Avraham Warshawsky (now deceased), Prof. Mati Fridkin and Ph.D. student Hailin Zheng from China – have received U.S. and worldwide patents on VK-28, HLA-20 and M30. Youdim says the three drugs could treat and perhaps prevent a range of diseases including Parkinson’s, Alzheimer’s, Huntington’s and amyotrophic lateral sclerosis (ALS).
Unlike other drugs currently used against these disorders – which attempt to replace the functions lost by dying neurons – these drugs halt the neuron destruction itself. Normally, iron is a helpful partner in the body’s metabolism, shuttling electrons between molecules in chemical reactions that break down fats, carbohydrates and proteins, and provide energy to cells. Because iron is so reactive, the body usually keeps tight control over the amount and activity of iron circulating in the brain and other organs.

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...
