The theory explaining how polarons carry energy in crystals can be applied to long molecules called polypeptides—which can fold into proteins.  Two new computational tools, MSMuTect and MSMutSig, could help reveal how often mutations in common DNA features called microsatellites appear in, and contribute to, cancer.  A Northeastern research team has developed new technology that optimizes DNA sequencing using nanophysics and electric currents.  Nevertheless, the accumulation of DNA damage is a cause of aging. A team of scientists based at CECAD at the University of Cologne is now trying to better understand the damage to the genome driving the aging process.  By taking a different approach, however, researchers at Houston Methodist made a surprising discovery leading to the development of technology with the ability to rejuvenate human cells.  The stiffness or elasticity of a cell can reveal much about whether the cell is healthy or diseased. Cancer cells, for instance, are known to be softer than normal, while asthma-affected cells can be rather stiff.  Scientists at the University of Bonn have succeeded in observing an important cell protein at work using a method that measures structural changes within complex molecules.  Scientists have now explored a modified form that can produce light-generated electrons and store them for catalytic hydrogen production even after the light has been switched off. They present this biomimetic photosynthesis approach in the journal Angewandte Chemie.  Scientists at The Australian National University (ANU) have designed a nano crystal around 500 times smaller than a human hair that turns darkness into visible light and can be used to create lightweight night-vision glasses.  Magnets instead of antibiotics could provide a possible new treatment method for blood infection.  One of the biggest challenges in cognitive or rehabilitation neurosciences is the ability to design a functional hybrid system that can connect and exchange information between biological systems, like neurons in the brain, and human-made electronic devices.
