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.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
