When someone is suspected of criminal activity, one of the most important questions they are asked is if they have a credible alibi. Playing back past events in our minds, however, is not like playing back a video recording. Recollections of locations, dates, and companions can become muddled with the passage of time.

Faulty metabolism of Parkinson’s medication in the brain linked to severe side effects

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 […]

The NHS and health services worldwide need to develop policies on when patients should be “re-contacted” about faulty genes, as the current lack of guidance creates a dilemma for health services, experts have warned. Re-contacting happens when new information about a patient’s genes comes to light—such as when a certain gene mutation is reclassified as a cancer risk. A policy […]

Researchers identify faulty ‘brake’ that interferes with heart muscle’s ability to contract and relax

Hypertrophic cardiomyopathy (HCM) is the most common genetic disease of the heart and a leading cause of sudden cardiac death in young people and athletes. Scientists have long known that the condition’s cardinal feature—an unusually thick heart muscle that contracts and relaxes abnormally—is fueled by some glitch in the heart’s molecular machinery. Yet, the sparkplug that ignites such disordered muscle […]

Recurrent miscarriage linked to faulty sperm

The research, published in the journal Clinical Chemistry, revealed that, compared to men whose partners had not experienced miscarriages, the sperm of those involved in the study had higher levels of DNA damage. The study […]
