For the first time, therapeutically effective medications are now available for Alzheimer’s disease. Effective symptomatic therapies also exist for Parkinson’s disease. However, a prerequisite for successful treatment is early diagnosis – ideally through a simple blood test conducted as part of a preventive screening, even before clinical symptoms appear. A research team led by Professor Klaus Gerwert from Ruhr University Bochum, Germany, has developed just such a blood test. It is based on the immuno-infrared sensor, a novel platform technology to which the Journal of Physical Chemistry B dedicates its cover story in its issue from April 24, 2026.

It has previously been shown that young, very fit people have an increased risk of atrial fibrillation. A new study of over one million young Swedish men shows that this risk is less than previous calculations showed, and that the benefits in terms of reduced risk for all other cardiovascular diseases outweigh the risk.

IBD, which comprises the inflammatory conditions Crohn’s disease and ulcerative colitis, affects about 1.6 million Americans, many of whom cannot be effectively treated. This mostly is due to a lack in understanding of what exactly causes the increased inflammation, fibrosis, and compromised intestinal barrier that underlie this disease and its manifold symptoms. 

 

A new study, published in Nature Biomedical Engineering and led by Wyss Founding Director Donald Ingber, developed donor-specific microfluidic Organ Chip models of colon that replicate major hallmarks of IBD in vitroin an unprecedented way. Their approach pinpointed new drivers of IBD progression and, for the first time, demonstrated a direct impact of pregnancy hormones on IBD severity in female IBD patient chips and recapitulated the enhanced initiation of cancer formation in IBD tissues.

New data from the European Centre for Disease Prevention and Control (ECDC) show that sexually transmitted infections reached record levels across Europe in 2024, driven by sharp rises in gonorrhoea and syphilis, and widening gaps in testing and prevention. Targeted action is urgently needed to prevent further spread, including among women of reproductive age.
