Did ‘Soylent Green’s’ Predictions About 2022 Hold Up?
In the spring of 1973, the movie Soylent Green premiered. The film drops us into a New York City that’s overcrowded, polluted, and dealing with the effects of a climate catastrophe. Only the city’s elite can afford clean water and real foods, like strawberry jam. The rest of the population relies on a communal food supply called Soylent. There’s Soylent Red, Soylent Yellow… and a new product: Soylent Green.
The year the film takes place? 2022. And spoiler alert: Soylent Green is people.
While the 2022 the film depicts is—thankfully—much darker than our current situation, <a href="https://www.sciencefriday.com/segments/soylent-green-2022/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">the message still holds up</a>. When the film premiered, Rachel Carson’s Silent Spring and the Clean Air Act were very much in the country’s consciousness. 50 years later, warmer temperatures, soil degradation, and social inequality are more relevant than ever.
Joining Ira to talk about the importance of Soylent Green 50 years later is Sonia Epstein, associate curator of science and film at the Museum of the Moving Image in New York City. Also joining is soil scientist Jo Handelsman, director of the Wisconsin Institute for Discovery in Madison, Wisconsin.

 
The National Science Foundation Has A New Goal: Entrepreneurship
The South By Southwest festival in Austin this year was the site of at least one unusual event: a press announcement by the head of the National Science Foundation, the primary federal agency tasked with funding and supporting fundamental research and investing in the education of young scientists in those fields.
NSF director Sethuraman Panchanathan announced he was creating a new directorate for Technology, Innovation, and Partnerships (TIP) to focus on “use-inspired” research that can be brought to commercial markets, in partnership with businesses and entrepreneurs. The goal, Panchanathan said in a press release in March, was to <a href="https://www.sciencefriday.com/segments/nsf-enterpreneurship/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">“accelerate the development of new technologies and products that improve Americans’ way of life, grow the economy and create new jobs, and strengthen and sustain U.S. competitiveness for decades to come.”</a>
Panchanathan talks to Ira about what this new chapter means for the NSF, the future of basic research with no immediate commercial uses, and the challenges of persuading the public that failure, as much as success, is inherent to science.

 
The Colorado River Misses Its Snow
High in the Rocky Mountains, under thin air and bluebird skies, the Colorado River basin is slowly filling its savings account. Craggy peaks become smooth walls of white and piles of snow climb conifer trunks, covering even the deepest, darkest corners of the woods with a glimmering blanket.
The snow that accumulates in the mountains of Colorado and Wyoming will eventually become water in the Colorado River. Some of it will flow as far south as Mexico, running through kitchen faucets in cities and suburbs along the way, or watering crops that keep America fed through the winter.
Year by year, those piles are getting slightly smaller and melting earlier — slowly exhibiting the sting of a warming climate. The way we measure the snow is changing too, as a shifting baseline for what counts as “average” paints a somewhat deceptive picture of how much snow is stored up in the mountains.

Exploring Neptune’s Unusual Seasons
Planetary scientists monitoring how the outer planets change over time have made a surprising observation of springtime on the planet Neptune. As the planet moves towards summer in its southern hemisphere, one might expect it to get warmer—but in data taken over 17 years, <a href="https://www.sciencefriday.com/segments/neptune-unusual-spring/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">researchers observed that the average temperature actually seems to be declining</a>. One theory involves the conversion of atmospheric methane, which traps heat, to ethane or other hydrocarbon compounds that release heat more readily, but more research is needed.
The researchers also spotted the rapid formation of a hot-spot at the south pole of Neptune, with an increase of some 11 degrees C over just two Earth years. Models had predicted a temperature swing of perhaps 15 degrees over the entire seasonal cycle.
These findings were reported this week in the Planetary Science Journal. Scientists don’t know very much about Neptune—it’s over 30 times Earth’s distance from the sun, and gets only one nine-hundredth of the sunlight. It takes around 165 Earth years to complete an orbit, meaning that the researchers’ 17 years of data account for only a small fraction of one season. Because of the planet’s tilt and its long orbit, the last time the planet’s north pole was visible from Earth was in the 1960s. And we’ve only visited once, via the Voyager spacecraft, over 30 years ago.
Michael Roman, a planetary scientist at the University of Leicester in the UK, and one of the authors of the report, joins Ira to talk about <a href="https://www.sciencefriday.com/segments/neptune-unusual-spring/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">the strange springtime on Neptune—and the planet’s many remaining mysteries</a>.

 
Transcripts for each segment will be available the week after the show airs on <a href="https://www.sciencefriday.com/" target="_blank">sciencefriday.com</a>.
