With Artificial Intelligence (AI) able to deliver diagnostic advances for clinicians and patients, the focus has shifted towards ensuring the technology is used in an ethical and responsible way. As evidence emerges of a gap in research on ethical deployment of AI, Dr Gopal Ramchurn is embarking on a three-year research project that will look at setting parameters for AI usage, with a key aspect…
One of the downsides to getting older is that skeletal muscle loses its ability to heal after injury. New research from the University of Pittsburgh implicates the so-called “longevity protein” Klotho, both as culprit and therapeutic target. The paper, published this week in Nature Communications, showed that, in young animals, Klotho expression soars after a muscle injury, whereas in old…
Women who work intermittent night shifts and do not follow a healthy lifestyle face an especially high risk of type 2 diabetes, suggests a study published by The BMJ. The researchers found that the risk of type 2 diabetes is actually higher than simply adding the individual risks associated with unhealthy lifestyle and shift work together, indicating that combining an unhealthy lifestyle with…
Using technology similar to the type that powers facial and speech recognition on a smartphone, researchers at the University of North Carolina Lineberger Comprehensive Cancer Center have trained a computer to analyze breast cancer images and then classify the tumors with high accuracy. In a study published in the journal NPJ Breast Cancer, researchers reported they used a form of artificial…
One day, MRI brain scans may help predict whether older people will develop dementia, new research suggests. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years, according to research at Washington University School of Medicine in St. Louis and the University of California San Francisco. The findings, presented at the…
Suicide is the 10th leading cause of death in the United States, claiming more than 44,000 people in the country every year, similar to the number of deaths caused by the opioid epidemic. Previous studies show that suicide tracks in families independent of the effects from a shared environment. Researchers at the University of Utah Health are using resources unique to the state to identify…
For patients who take medication to treat hypothyroidism, being treated with too much medication can lead to an increased risk of atrial fibrillation, a common heart rhythm disorder associated with stroke, a new study of more than 174,000 patients has found. The findings were presented by researchers from the Intermountain Medical Center Heart Institute in Salt Lake City at the American Heart…
The number of surgical interventions in Germany over the last ten years has increased by around 30%, but it would be wrong to talk of a heyday – mainly due to a lack of young talent, says Prof. Dr. Jörg Fuchs. The president of the German Society of Surgery (DGCH) and director of the Clinic and Polyclinic for Paediatric Surgery and Paediatric Urology at Tübingen University Hospital talks about…
A 4G symbol next to the signal strength bar on a smartphone assures fast data transmission. 5G, the next generation of technology, is already waiting in the wings and could herald a new era for tele-surgery, PD Dr. Michael Kranzfelder is convinced. However, there are a few obstacles to overcome first.
Hypotrichosis simplex leads to progressive hair loss already in childhood. A team of researchers led by human geneticists at the University Hospital of Bonn has now deciphered a new gene that is responsible for this rare form of hair loss. Changes in the LSS gene lead to impairment of an important enzyme that has a crucial function in cholesterol metabolism. The scientists now present their…
Scientists of the Helmholtz Centre for Infection Research (HZI) have now dissected the precise molecular mechanisms of WAVE complex activation, occurring in a process involving separable, independent steps.

With almost a thousand electrodes, and 384 recording channels on a single shank, the Neuropixels probe provides an unprecedented resolution for mapping brain…
The baroreceptor reflex is a fascinating medical phenomenon. The reflex is controlled by specialized neurons that react in just a fraction of a second to keep blood pressure fairly consistent. For example, when you stand up, your blood pressure normally drops—rapidly. Yet you don't faint thanks to baroreceptors, which tell your heart rate to increase and push more blood to your brain. A new…
Nanosystems that deliver anticancer drugs or imaging materials to tumours are showing significant progress, particularly those that respond to tumour-related stimuli, according to a review published in the journal Science and Technology of Advanced Materials. However, further research is still required to make sure these delivery systems are stable, non-toxic and biodegradable. Nanocarriers…
The complex structure of breast tumours makes treatment a medical challenge.
