In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum dots.
Kyoto-Osaka team uses hiPSCs to repair myocardial infarctions in rats. The creation of cardiac tissue-like constructs could offer an effective and convenient "woundplast" for repairing myocardial infarction.
A tool designed to more accurately predict the risk of heart attack in older patients undergoing non-cardiac surgery works significantly better than traditional risk assessment tools. By having more accurate information, older patients and their physicians can make an informed decision on whether to undergo surgery, UCLA researchers concluded.
Researchers have produced the first three-dimensional (3D) map of a molecular 'scaffold' called SgK223, known to play a critical role in the development and spread of aggressive breast, colon and pancreatic cancers.
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers.
Glaucoma is a serious disease associated with increased intraocular pressure which often leads to blindness. One of the ways to treat glaucoma is to reduce aqueous humour secretion in the ciliary body of the eye by suppressing (inhibiting) activity of special enzymes - carbonic anhydrases. Russian scientists have designed new compounds that can effectively reduce intraocular pressure.
