<p>Folks interested in science should be interested in Retraction Watch, which is now 15 years old. Started by medical journalists Ivan Oransky & Adam Marcus, the site is the only one (that I know of, anyway) that uncovers and tracks scientific retractions, errors, and other controversies. My best friend of 27 years happens to work there too, but that's besides the point! They do vital work no one else is doing. Their year-end summary is impressive. </p><p><a href="/tags/science/" rel="tag">#science</a> </p><p><a href="https://retractionwatch.com/" rel="nofollow"><span class="invisible">https://</span>retractionwatch.com/</a></p>
