Spring Climate Effects, Octopus Sleep, Housing and Health. March 26, 2021, Part 2

In New York, Essential Workers Face Eviction If you walk through many towns during this pandemic, you can tell that something is different just by looking at the storefronts. Some businesses have limited hours, others have capacity restrictions. Still other businesses are temporarily closed. Some are gone altogether. The pandemic has also had other financial effects that are harder to see—and often, that financial stress is hitting the same people who are already most likely to have gotten sick. According to a recent analysis of court data, New York City landlords seek evictions nearly four times more often in the neighborhoods hardest hit by COVID-19 deaths—neighborhoods that also tend to be largely Black and Latino. Areas with high numbers of evictions also tend to be where many of the city’s “essential workers” live—people with public-facing jobs, with limited options for avoiding the risk of infection.  A recent New York Times article dove into the dataset created by the Association for Neighborhood and Housing Development. Stefanos Chen, the article’s author, joins Ira to talk about how the housing market in New York has been affected by the pandemic, and the ways that certain neighborhoods have been disproportionately threatened by eviction.  Allergy Season Is Blooming With Climate Change Spring is in the air, and for many people that means allergy season is rearing its ugly head. If it feels like your allergies have recently gotten worse, there’s now data to back that up. New research shows that since 1990, pollen season in North America has grown by 20 days and gotten 20% more intense, with the greatest increases in Texas and the Midwest. This is because climate change is triggering plants’ internal timing to produce pollen earlier and earlier. It’s a problem that’s expected to get worse. SciFri producer Kathleen Davis speaks with William Anderegg, assistant professor at the University of Utah’s School of Biological Sciences about pollen counts, and pollen as a respiratory irritant. Flowers Are Finding New Hues In A Climate Crisis It’s that time of the year where flowers bloom and the world starts to feel more colorful after a dormant winter. But what if the colors of the flowers we see now aren’t the same as they were a century ago? New research from Clemson University scientists finds that climate change has impacted the hues of flowers. Temperature and aridity changes since 1895 have caused some flowers to go from purple to white, and others from white to purple. Ira is joined by the lead researcher and Clemson Department of Biological Sciences graduate student Cierra Sullivan to talk about these strange changes, and the possible impact on the pollinators we know and love. I Dream Of Octopuses, But Do They Dream About Me? Sleep is nearly universal in the animal kingdom, but how animals sleep is not the same. Studies have found that in mammals, giraffes get the least amount of shut eye, while koalas can sleep up to 22 hours a day.  There are also different types of sleep cycles—including a stage called rapid-eye movement or REM, which is often compared to non-REM sleep. A team of researchers wanted to study these different sleep cycles to understand how they might be connected to learning and memory. The scientists turned to the octopus as their study subject, selected for their complex behaviors and large brains. Their results were recently published in the journal iScience.  Neuroscientist Sidarta Ribeiro, one of the authors on the study, joins Science Friday to explain how you measure the sleep cycles of an octopus, and what this can tell us about if an octopus might dream.
