Decades Of Alzheimer’s Research Could Be Based On Fraudulent Data

Alzheimer’s disease is a devastating brain disorder that slowly affects memory and thinking skills. For many people who worry that loved ones may succumb to this disorder, the possibility of research in the field of Alzheimer’s is a balm of hope. However, a massive report from Science Magazine highlights a startling discovery: that decades of Alzheimer’s research are likely based on faulty data. Alzheimer's researchers are grappling with the revelation, and what it means for future research of the disease.

In other science news of the week, scientists have identified pits on the moon that are a comfortable temperature: averaging 63 degrees Fahrenheit. But don’t plan that space vacation yet—research finds that air pollution from space-bound rockets has an exorbitantly high effect on global warming—much more than traditional airplane travel.

Joining guest host Sophie Bushwick to discuss these stories is Maggie Koerth, science writer for FiveThirtyEight based in Minneapolis, Minnesota. They also discuss how childhood vaccinations have dropped dramatically during the COVID pandemic, and why this is likely tied to New York’s first Polio case in nearly a decade. 

 

Higher Temperatures Are Bad For The Body

Across the globe, hundreds of millions of people have been dealing with extreme heat. The three most populated countries in the world—China, India and the United States—have been gripped by heat waves throughout the summer.

Extreme heat isn’t just uncomfortable: it can be deadly, putting strain on the organs and systems that keep us in equilibrium. Heat is especially dangerous for vulnerable populations such as the elderly, pregnant people, and those without access to air conditioning. In the United States, heat is responsible for more deaths than any other type of weather event.

Joining guest host Sophie Bushwick to talk about what high temperatures do to the body, and how we can protect our health and safety in a heat wave is Chris Uejio, associate professor of public health at Florida State University in Tallahassee, Florida. 

 

Protecting Piping Plovers Isn’t A Walk On The Beach

July is nearly through, and so is the piping plover’s nesting season. It's make-or-break time for these small, endangered shorebirds. There are roughly 8,000 piping plovers in the entire world. To put that in context, birders often get really excited to see a rare bird like a snowy owl. But there are about 28,000 snowy owls in the world, three times the number of piping plovers. 

Since piping plovers make their nests along the water and out in the open, their chicks are very vulnerable to being gobbled up by predators. And a major reason for their decline in numbers is human development along the beaches, lakes, and rivers where piping plovers lay their eggs. 

SciFri radio producer Shoshannah Buxbaum went out to Fort Tilden in Queens, NY to report on a volunteer-run conservation effort along the New York City coastline. And later in the segment, Michigan radio reporter Lester Graham talks with guest host Sophie Bushwick about the unique challenges and triumphs of the piping plovers who nest along the Great Lakes.

 

This Glove Takes Inspiration From An Octopus’ Arm

Octopuses have more than 2,000 suckers on eight arms, and each one is controlled individually, making these critters incredibly dextrous. So when a team of researchers wondered how to design a glove that could hold onto slippery objects underwater, they turned to octopuses for inspiration. Ultimately, they created something they’re calling an octa-glove. Guest host Sophie Bushwick talks with Michael Bartlett, an assistant professor of mechanical engineering at Virginia Tech, about his team’s engineering, and what they learned from the ambidextrous creatures.
