Flexible electronics breakthrough could enhance biosensor technology, from wearables to soft-robotic implantable systems. Semiconductors are moving away from rigid substrates, which are cut or formed into thin discs or wafers, to more flexible plastic material and even paper thanks to new material and fabrication discoveries. The trend toward more flexible substrates has led to fabrication of numerous devices, from light-emitting diodes to solar cells and transistors.

Breakthrough infections greatly enhance immune response to variants of the virus that causes COVID-19, according to a newly published study from Oregon Health & Science University.

The laboratory results, published online ahead of print today in the Journal of the American Medical Association (JAMA), reveal that a breakthrough infection generates a robust immune response against the delta variant. Authors say the findings suggest the immune response is likely to be highly effective against other variants as the SARS-CoV-2 virus continues to mutate.

A healthy diet and a little exercise appear to be good for arthritis, even on the cellular level. A team led by Washington State University researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination not only decreased arthritis inflammation markers in the cells but improved the production of desired proteins normally found in healthy cartilage.

While still at an early stage, the findings suggest a new procedure could be developed to treat cartilage cells extracted from a patient to grow a supply of cells or a tissue to be re-implanted.

Monash University, Australia scientists have discovered an enzyme that is key to why exercise improves our health. Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of aging on metabolic health, including type 2 diabetes.

The proportion of people worldwide over 60 years old will double in the next three decades and by 2031, more than six million Australians will be over 65 years old. The incidence of type 2 diabetes increases with age so this aging population will also result in an increased incidence of the disease globally.

One of the main reasons for the increased prevalence of type 2 diabetes with age i...
