Neurosciences August 13, 2026 DEAR MAYO CLINIC: My spouse will tell me occasionally that their hands and feet “fall asleep,” and they experience numbness, tingling and a pins-and-needles sensation. Is this normal, or does it require medical attention?   ANSWER: Most people experience numbness or the familiar pins-and-needles sensation from time to time. Often, it’s harmless and happens because you’ve been sitting, standing or sleeping in a position that puts temporary pressure on a nerve. Once you change positions, the sensation usually goes away within a few minutes.  However, these symptoms can sometimes signal an underlying medical condition. They can occur when…

Medical Innovation August 13, 2026 Gary Lorenz As the fire chief for the city of Fargo, North Dakota, Gary Lorenz is accustomed to high-stress emergencies.   “Firefighters are problem solvers,” Gary explains. “When people call 911, and the dispatchers aren’t sure whom to send, they send the fire department.”   But on Oct. 7, 2025, Gary faced a crisis he could not simply delegate.   During a routine scan for an unrelated issue, doctors discovered a tumor on his left kidney.   Stunned by the news, Gary recalls pacing the floor at his headquarters fire station, feeling overwhelmed and not knowing what to do next.    “I am kind of a fixer,” says Gary. “Whether it’s mechanical or other things,…

Key points: As the school year begins, teachers often devote significant time to planning lessons, reviewing standards, organizing classrooms, and establishing routines. While these are all essential components of effective teaching, they cannot replace the importance of creating a positive classroom culture. Students learn best in environments where they feel safe, valued, challenged, and connected to the adults around them. In the words of former president Teddy Roosevelt, “People don’t care how much you know until they know how much you care.” Every decision educators make should be guided by what’s best for kids. When that mindset drives the classroom’s…

Medical Innovation ByJulie Ferris-Tillman, Ph.D. August 12, 2026 In this episode of “Tomorrow’s Cure,” experts explore how platform-based models can help health systems use data and artificial intelligence (AI) to advance healthcare. Recorded at the fifth annual PlatforMed event hosted by Mayo Clinic, these leaders shared insights with more than 260 health system executives and Tomorrow’s Cure.   In this special episode, hear from Micky Tripathi, Ph.D., chief AI implementation officer for Mayo Clinic; Gelareh Zadeh, M.D., Ph.D., David C. and Flora C. Pratt Distinguished Chief Medical Officer for Mayo Clinic Platform; Farhana Alarakhiya, chief data information officer, Aga Khan University;…

Key points: As students return to classrooms across America this fall, parents are focused on school supplies, class schedules, and academic expectations. Teachers are preparing lesson plans, organizing classrooms, and hoping for a successful year. Yet one of the biggest obstacles to student success won’t be found in a math textbook or reading assignment. It is listening. Every day, teachers ask students to “listen carefully,” “pay attention,” or “focus.” Yet almost no one ever teaches children how to listen. That assumption comes with a tremendous cost. Teachers across the country consistently report that one of their greatest daily challenges is simply getting…

Key points: There’s a wise quote that says, “Kids don’t care about your expectations until they know you care about them. Connection is the foundation everything else stands on.” As an educator, I firmly believe this to be true. Students decide very quickly when they walk into a classroom whether that space feels safe, calm, and worth engaging with. The attitudes and impressions they form this week of school will go on to direct their actions for the rest of the year. That’s why I refer to the first five days of school as “The Big 5” – these are…

Orthopedics/Sports August 10, 2026 More than 200,000 joint replacement patients have helped Mayo Clinic personalize care, improve outcomes and shape the next generation of treatment.  Bob Morreale For nearly six years, Bob Morreale has lived with a shoulder replacement. Most days, he does not think about it at all.  That, he says, is the point.  For Bob, 56, of Rochester, Minnesota, the road to shoulder replacement began decades earlier. A former Division III college baseball pitcher, he sustained shoulder injuries that led to instability, tissue damage, previous surgeries, and eventually, osteoarthritis. Over time, pain became part of daily life.   “Turning…

Key points: Over the last 15 years, I have observed a recurring pattern. A new principal, whether brand new to the role or a veteran principal arriving at a new school, wants to make an immediate impact. It makes sense. We want to show that we were the right choice for the job. We want to demonstrate that we are willing to work hard and improve things. We want to help. I remember arriving at one school and immediately wanting to give the librarian feedback. I had opinions about how the library was organized, which books were displayed, and even…

Key points: America’s schools are moving quickly to respond to the rise of artificial intelligence, with parents, teachers, administrators, and lawmakers working to wrap their arms around what this means for student education.  But regulation that comes ahead of a clear definition of preparedness may set students back in the AI race. For the future of America’s students — and economy — leaders need to first define what the future of career preparedness looks like.  The speed at which education leaders have moved to respond to AI has been nothing short of remarkable. Just a few years ago, there were…

Cardiovascular August 6, 2026 DEAR MAYO CLINIC: My neighbor spends a lot of time outdoors gardening and doing yard work, especially during the summer. Recently, after working outside on a hot day, she became lightheaded and noticed her heart racing. She suspected dehydration was to blame, but it made me wonder: Can dehydration affect your heart? When should symptoms like this be taken seriously?  ANSWER: Dehydration can affect much more than your thirst. It also can place extra stress on your heart and cardiovascular system.  Think of the heart as a pump. For it to work properly, enough blood needs…
