Inside the Boom of Urgent Care: How It’s Changing...

The Pulse ·

2026/04/02

The number of urgent care centers in the U.S. has doubled over the past decade, and it isn’t hard to see why — they fill a void in the market. Urgent care offers quick and convenient access to medical care when patients can’t get an appointment to see their primary care doctor, but their issue doesn’t seem to warrant an ER visit. But the rapid rise of urgent care has come with some growing pains — questions over the quality of care, and how they’re affecting doctor-patient relationships. On

2026/04/01

Have you ever looked in the toilet bowl and wondered, ‘Is that normal?’ Well, you’re not alone — and according to neurogastroenterologist Trisha Pasricha, it’s time to talk about poop. Pasricha says understanding what’s normal about your bowel movements isn’t just a silly or squeamish conversation, but one that can be lifesaving. Digestive issues affect millions of Americans, yet many of them are scared to discuss them, even with their doctors. Meanwhile, the rate of irritable bowel

The Problem with Being Perfect: How Unrealistic...

The Pulse ·

2026/03/26

We often think of perfectionism as a virtue; a kind of shorthand for high standards, a solid work ethic, and attention to detail.But in reality, perfectionism can be a paralyzing force — like sand wedged in the gears of our minds. It slows us down, makes us question our choices, and traps us in an endless cycle of tweaking and re-tweaking, unable to move on to the next task. It can even have consequences for our health, as we push ourselves beyond our limits, in pursuit of impossible

Space exploration relies heavily on the interest of the public — the voters, and taxpayers, who are ultimately footing the bill. But that support and excitement can be fickle. When space missions go well, and deliver new insights, the payoff is cheering crowds and increased support. But when they don’t, the result can be reduced funding, canceled missions — and even deaths.That means, with each mission, the pressure is on to push boundaries, break new ground, and get everything right.
