How Has The War In Ukraine Shaped The Global Energy Market?
Russia’s war on Ukraine sent shock waves through the global energy market. The United States and the United Kingdom stopped importing Russian oil and gas, and the European Union set a target of reducing their reliance on Russian fossil fuels by two thirds.
In the short term some countries may start relying more on dirty fossil fuels like coal to cushion the economic impact of the shifting energy market. However, some experts believe the current political situation <a href="https://www.sciencefriday.com/segments/ukraine-energy-market/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">may inspire a lasting transition to clean energy</a>.
Guest host John Dankosky talks with Tim Revell, United States Deputy Editor at New Scientist about the changes to the global energy market and other <a href="https://www.sciencefriday.com/segments/ukraine-energy-market/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">top science news of the week</a>, including the latest on the BA2 covid-19 variant, Orangutan slang, the winner of the prestigious Abel prize in mathematics, lettuce genetically modified to prevent bone loss, and robots who learned to peel bananas without crushing them.
 

 
Why Climate Change May Bring More West Nile Virus To The U.S.
Michael Keasling of Lakewood, Colorado, was an electrician who loved big trucks, fast cars, and Harley-Davidsons. He’d struggled with diabetes since he was a teenager, needing a kidney transplant from his sister to stay alive. He was already quite sick in August when he contracted West Nile virus after being bitten by an infected mosquito.
Keasling spent three months in hospitals and rehab, then died on Nov. 11 at age 57 from complications of West Nile virus and diabetes, according to his mother, Karen Freeman. She said she misses him terribly."I don't think I can bear this," Freeman said shortly after he died.
Spring rain, summer drought, and heat created ideal conditions for mosquitoes to spread the West Nile virus through Colorado last year, experts said. West Nile killed 11 people and caused 101 cases of neuroinvasive infections—those linked to serious illnesses such as meningitis or encephalitis—in Colorado in 2021, the highest numbers in 18 years. The rise in cases may be a sign of what’s to come: As climate change brings more drought and pushes temperatures toward what is termed the “Goldilocks zone” for mosquitoes—not too hot, not too cold—scientists expect West Nile transmission to increase across the country.

Millions Of Iowa Chickens Infected With Deadly Strain Of Bird Flu
Iowa and federal agriculture officials have confirmed <a href="https://www.sciencefriday.com/segments/iowa-chickens-bird-flu/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">a deadly strain of bird flu in a large commercial flock of egg-laying hens in northwest Iowa’s Buena Vista County</a>. It’s the fourth case of bird flu in the state and the largest flock to date to be infected by this year’s outbreak. Chloe Carson, a spokesperson for the Iowa Department of Agriculture and Land Stewardship, said Friday that initial reports indicate there are approximately 5.3 million birds in the flock. Carson said the department won’t have exact numbers for a few days. The numbers will be released by the U.S. Department of Agriculture once all the birds have been destroyed to prevent the disease from spreading.
It’s the second confirmed case of bird flu in Buena Vista County this year. The virus was confirmed in a commercial flock of nearly 50,000 turkeys in the county on March 6. The deadly strain was also confirmed in a flock of more than 915,000 commercial egg-laying hens in southwest Iowa’s Taylor County on March 10 and a backyard flock of nearly 50 chickens and ducks in Pottawattamie County on March 1. Agriculture officials have cautioned producers and backyard flock owners to keep their birds away from wild birds that are migrating. They can carry the virus in their saliva or feces and show no signs of infection.
Bird flu has been found in commercial and backyard flocks in 17 states, according to the U.S. Department of Agriculture. Iowa has about 56 million egg-laying chickens and is the top egg-producing state in the country. In the 2014-2015 bird flu outbreak, Iowa and Minnesota were hit the hardest. More than 50 million birds were killed in that outbreak, including nearly 33 million in Iowa.

 
5,000 Total Exoplanets Have Now Been Discovered
This week, the NASA Exoplanet Archive <a href="https://www.sciencefriday.com/segments/5000-exoplanets-found/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">logged the 5,000th confirmed planet outside of our solar system</a>. This marks a huge advance since the first exoplanet discovery in 1992, when astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. Now, the Archive contains confirmed sightings of planets in a wide range of shapes and sizes—from "hot Jupiters" to "super Earths"—but they still haven’t found any solar systems just like our own. In many cases, all astronomers know about these distant planets is their size and how far away from their stars they orbit.
The TESS (Transiting Exoplanet Survey Satellite) mission currently in orbit may eventually add 10,000 more candidates to the lists of possible planets. The Nancy Grace Roman Space telescope and ESA’s ARIEL mission, both planned for launch later this decade, could add thousands more. And the James Webb Space Telescope, currently undergoing commissioning, will attempt to characterize the atmospheres of some of the planets astronomers have already discovered.
Astronomer Jessie Christiansen, the NASA Exoplanet Archive Project science lead, joins John Dankosky to talk about what we know about <a href="https://www.sciencefriday.com/segments/5000-exoplanets-found/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">planets around distant suns, and how researchers are working to learn more about these far-off worlds</a>.
