PRO en de vakbonden gaan niet akkoord met een bezuiniging van 3 miljard op sociale zekerheid. Geld dat gespaard is door werknemers en werkgevers als verzekering tegen ontslag of ziekte. Dit geld is niet van het kabinet. Het is opgebracht door alle werkende mensen in Nederland. Dus blijf er vanaf.

On prostate cancer screening. I chose to screen because of family history - cancer was found (low grade, early stage). I had active surveillance with MRI/biopsy for a few years. Then when it progressed, I had Nanoknife focal therapy. Modern methods allow control with less overtreatment. #r4today

Paper out in collaboration with the Liedewij Laan group Starting from an interest in PTMs and protein modification, we developed a sortase substrate for farnesyl incorporation. And learned, the hard way, how difficult these compounds are to work with, despite their simple structure 😳

Killjoy hier: 'Onthullen' dat FvD 'flirt' met extreemrechts is echt geen flex. Het levert applaus op en vaste een journalistieke prijs. Want onze sector houdt van vorm. Maar we zijn al jaren te laat met dit soort 'bewijzen'; waar blijft het bestrijden? We zijn lui en laat.

You probably know Photodynamic Therapy (PDT), but how about Radiodynamic Therapy? Now out in Cell Reports Physical Science, Bing Xu shows how lowering the radiation dose rate on solutions of the photosensitizer Chlorin e6 leads to increased production of highly cytotoxic singlet oxygen.

I really dislike how science has started calling almost any fancy computational technique AI. 🧪 The framing of this entire article makes it sound like a benevolent AI independently made these drugs. That is *pure fantasy*. Instead: a team of scientists made a machine learning model for a study.

Article on BBC news. 
Title: AI designs antibiotics for gonorrhoea and MRSA superbugs
Description: Two new potential drugs have been designed by AI to kill drug-resistant bacteria, in a major Massachusetts Institute of Technology study.
