Until now, the reason why the drug levodopa (L-Dopa), which reduces the motor symptoms of Parkinson’s disease, declines in efficacy after a few years’ use has been unknown. A side effect that then often occur is involuntary movements. A Swedish–French collaboration, led from Uppsala University, has now been able to connect the problems with defective metabolism of L-Dopa in the brain.

Researchers have clarified the contribution of key cancer-associated genes, proteins and signaling pathways in thread and neck cancers while proposing potential new treatment strategies.

In a new paper published in Cell, researchers report that all cancer cells – rather than just a subset – have the ability to switch to a protective state in response to a threat, such as chemotherapy.

Researchers have found a way to mimic conditions in intestines, giving them a mechanical model for the real-time growth of bacterial infections. This simplifies simulations of the human intestine, making it more practical to find treatments for diseases like infectious diarrhea.

Touted by makers as a “healthy” alternative to traditional nicotine cigarettes, new research indicates the chemicals found in e-cigarettes disrupt the gut barrier and trigger inflammation in the body, potentially leading to a variety of health concerns.

By comparing thousands of bacterial genomes, scientists have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.

Researchers use a novel probe to witness how a "matchmaker" molecule puts the brake on cell division until components are ready to be split.

Chinese scientists from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) have found a gene that plays an important role in helping rice adapt to low soil nitrogen.

E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect according to new research.

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.
