Oxidative stress is implicated in a fast-growing list of human conditions, from the superficial (e.g., wrinkled skin) to the deadly: diseases such as cancer, heart disease and neurodegenerative disorders including Lou Gehrigs disease (amyotrophic lateral sclerosis or ALS).
Researchers at The Jackson Laboratory announced that they have located a gene that protects certain brain and retinal neurons from oxidative stress, and prevents neurodegeneration.
Many normal metabolic functions produce free radicals--highly unstable forms of oxygen. Despite their notoriety, these molecules in fact have several beneficial roles, such as helping white blood cells attack bacteria, viruses and virus-damaged cells. Oxidative stress occurs when the amount of free radicals exceeds the normal antioxidant capacity of a cell, leading to cell damage.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
