Alzheimer's disease affects at least five and a half million people in the United States. One of the greatest challenges in trying to treat the disease is catching it early enough. There's currently no reliable way to diagnose Alzheimer's until symptoms like memory loss are already recognizable. And by that time the brain has suffered years if not decades worth of damage. That's likely why many promising drug trials in recent years have failed. But a test capable of diagnosing Alzheimer's years

" The Perseids are caused by the debris left behind by comet Swift-Tuttle, which is one of the bigger comets in the solar system. And every year in middle of August we run into the debris trail. And when that debris hits our atmosphere at 132,000 miles per hour, it burns up and leaves these brilliant streaks of light we call Perseid meteors." - Bill Cooke This week on Living Lab Radio: Suzanne Schindler of Washington University in St. Louis says a new blood test for Alzheimer's disease could be

“Old Town Road,” Lil Nas X’s country/western rap hit, is now not only genre-breaking, it’s record-breaking. It has held Billboard’s number one spot for 17 weeks, breaking the record previously set by the 2017 hit "Despacito" and, back in 1995, "One Sweet Day" by Mariah Carey and Boyz to Men.

Eight critically endangered North Atlantic right whales have died this summer, several of them hit by ships. In the last two years alone, 20 North Atlantic right whales have been found dead in Canadian waters. Of the 11 that could be studied, seven were found to have died as a result of vessel strikes. That has prompted Canada's Department of Fisheries and Oceans to announce a new round of funding to develop better ways for ships to find whales and avoid hitting them. One of those technologies

Twenty dead in El Paso, Texas; nine in Dayton, Ohio. Three - including two children - killed at the Gilroy Garlic Festival. And a dozen shot at the Brownsville Old Timers' Block Party in Brooklyn.

"There are some benefits to sounding like things we've heard before. At the same time, if something's exactly the same as what we've heard before, it's not going to get any attention. There's nothing new about it. So there's this nice blend of novelty and familiarity, of similarity and difference, of new and old. You can almost think about it as a Goldilocks effect - not too hot, not too cold, but just right - that really helps things in culture succeed." - Jonah Berger

Extreme heat in Europe and the continental U.S. has made headlines this summer. What you may not have heard about is what’s been going on in Alaska: 90 degree temps in the arctic, wildfires and rare lightning storms, and the ground literally collapsing due to the melting of permafrost.

We've all heard of conspicuous consumption -- big fancy houses, big fancy cars, designer clothes, and luxurious vacations. That kind of lifestyle comes with a big price tag and a big carbon footprint. But here's the thing. We are all consumers. And the food we buy and the clothes we wear have environmental impacts that we often underestimate or ignore altogether.

Einstein's theory of general relativity was revolutionary when it was introduced. Over the past century, aspects of the theory have been proven in experiment after experiment and much of it has become an assumed underpinning of daily life, even for non-scientists. Take Einstein’s description of gravity. Gravity is gravity, right? How strong it is depends on the mass of the objects involved. Or maybe not.

"Once you have an abrupt event like this - the ground cracks and opens up - it's not something that can just be undone by a cold year, because you've already exposed all this ground. Some of the material is just falling into lakes. You're losing ground material and you just can't go back in a human relevant timeframe." - Sue Natali This week on Living Lab Radio: Climate scientist Sue Natali has just returned from the Alaskan Arctic, where she witnessed extreme heat, wildfires, lightning storms,
