With deep sorrow, I received the news of Dr. Eugene Braunwald’s passing, one of the greatest figures in world cardiology. His scientific legacy, clinical vision, and immeasurable contribution to generations of cardiologists will continue to live on in our daily practice and in the history of medicine. My heartfelt condolences to his family, friends, students, and to the entire cardiology community. May he rest in peace.

Harvard University just released free online courses. No payment required. Here are 10 courses you don't want to miss in 2026:
Community note
The listed courses were not "just released." Most have been available for years, with some receiving annual updates (e.g., CS50's 2026 versions in January). Not all are free: "AI Strategy for Business Leaders" costs $2,950–$3,200. Others can be audited for free on edX. classcentral.com/report/harvard… professional.dce.harvard.edu/programs/ai-st…

‘Urging talks’ just won’t cut it. 41 jobs on the chopping block at Heriot-Watt and the damage reaches far beyond staff and students. The government needs to step up.

The first time you start a research lab, there’s no manual. So I made one. A practical toolkit for postdocs and early-career faculty launching their first lab: hiring, startup planning, collaborations, and building a sustainable research program. zenodo.org/records/18883545

Half an hour after an Aer Lingus flight reached 30,000 feet, the captain made an announcement: “Ladies and gentlemen, this is your captain, Sean Thomas. Welcome aboard Flight 280, non-stop from Dublin to Chicago. The weather is perfect today, so we should have a pleasant, smooth, uneventful flight. So just get comfortable, sit back, relax, and… OH… WHAT THE HELL!!” The plane went completely silent. 😳 A few moments later, the captain came back on the intercom: “Ladies and gentlemen, I’m so sorry if I alarmed you. While I was speaking, Maureen - our new and rather clumsy flight attendant - accidentally spilled coffee in my lap. You should see the front of my pants!” From the back of the plane, a passenger shouted: “For the love of Jaysus, you should see the back of mine!” 🇮🇪😂
