Even tiny amounts of viruses can have disastrous consequences. RNA identification can reveal the type of virus present. A fast and sensitive technique based on optical detection has now been outlined in the journal Angewandte Chemie. Scientists from Germany and Finland have demonstrated the binding of an RNA target to a probe made of gold nanorods and a DNA origami structure. Chirality switches triggered by binding can be measured by circular dichroism spectroscopy.

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain.

People who participate in light to moderate physical activity, such as walking at least four hours a week or swimming two to three hours a week, may have less severe strokes than people who are physically inactive, according to a study published in the Sept. 19, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.

'ChemLife' research initiative at the University of Konstanz makes an quintessential contribution to study of DNA polymerases.

Artificial intelligence (AI) can be an invaluable aid to help lung doctors interpret respiratory symptoms accurately and make a correct diagnosis, according to new research presented at the European Respiratory Society International Congress.

Thermal ablation is a safe, effective treatment for early-stage lung cancer, according to a new study. The results show that ablation may be an effective alternative for patients who cannot undergo lung cancer surgery because of age or health status.

International collaborative research led by Ludwine Messiaen, Ph.D., shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications. These include non-optic brain tumors, mostly low-grade and asymptomatic, as well as cognitive impairment and/or learning disabilities. This study extends findings first reported in 2007 that included only 19 NF1 adults.
