(1) Our website was invaded by malware for an hour last Friday. Although this was quickly fixed, we want to share some lessons we learned. First, to protect any important online accounts, you should use a strong password of 8 or more digits, upper and lower case characters, and change it frequently. Unfortunately, people using automated methods are trying to guess passwords for their own purposes. Second, if a website asks you to open a file at a random moment, that may be malware - don't do it. Third, review your own security regularly, and consider anti-virus / anti-malware programs, even with a Mac. If you have any concerns about our website or about security in general, email or call us and we will respond as soon as possible.
(2) We are constantly looking for new Reviewers for our 7,000 topics, which we want to update every 1-2 years. Visit our newly updated Instructions for Reviewers page for more information.
(3) The Table of Contents of our Stains chapter now includes all 360 stains / biomarkers described in the chapter. The CD Markers chapter contains an additional 260 markers. We update these pages regularly, but let us know of any new markers we should include or other changes we should make.
(4) Our Feature Page for the month highlights Lab Accrediation, Education and CME, and includes A2LA, ARUP Laboratories and Clinical and Laboratory Standards Institute (CLSI) . Also check out our new monthly Mystery Image, on the right side of the Home Page.
