The omicron outbreak has slowed dramatically in the U.S. But cases are rising in Britain due to an omicron subvariant. There are signs the U.S. could also see a bump in cases in the coming weeks.

Stay safe out there, fabulous listeners! Feel free to drop us a line at ShortWave@npr.org.

Texas Governor Greg Abbott has directed the state's Department of Family and Protective Services to investigate certain gender-affirming care as possible child abuse, leaving parents of transgender youth feeling caught between two choices: support their children or face a possible investigation. Annaliese and Rachel are mothers living in Texas and both have transgender children. They speak to NPR about the emotional and mental toll this order has had on their families. And while the order is currently blocked by a judge, Chase Strangio, Deputy Director for Transgender Justice with the American Civil Liberties Union, explains the status of other anti-LGBTQ bills in other states.

Analysis of wastewater from sewage systems has provided an early warning system for the presence of Covid19 in communities – showing up in the water samples before people test positive. It’s also possible to identify the variants and even specific genetic mutations. Davida Smyth of Texas A&M University has been using this technique in New York and found intriguing results -forms of the virus not present in humans. The suggestion is that mutated forms may be infecting other animals, possibly those present in the sewers. An analysis of long Covid, symptoms of fatigue, and ‘brain fog’ which occur long after initial infection, show that around a quarter of those infected develop these symptoms. Lucy Cheke of Cambridge University discusses the implications.

The war in Ukraine has highlighted the importance of the region in supplying raw materials and energy to other countries, gas, cereal crops, and fertilisers in particular. As crop scientist John Hammond from Reading University explains stopping of fertiliser exports from Russia, in particular, could impact food security in many countries.

And with unseasonal fires already burning in the Western US Caroline Juang of Columbia University’s Earth Observatory gives us her analysis of the driving factors in the intensification of fires year on year.

Faced with one cake and eight hungry people, it’s pretty obvious how maths underpins reality. But as mathematics gets further from common sense and into seemingly abstract territory, nature still seems to obey its rules - whether in the orbit of a planet, the number of petals on a flower, or the structure of an atom.

But what exactly is the relationship between mathematics and reality? That’s the impossibly difficult question CrowdScience has been set this week by our listener Sergio in Peru. It’s one that’s been pondered by humans for millennia: the Greek philosopher Pythagoras believed “All is number”.

Is maths a human construct to help us make sense of reality - a tool, a model, a language? Does maths create its own reality? Or is it reality itself?

Is maths a human construct to help us make sense of reality - a tool, a model, a language? Does maths create its own reality? Or is it reality itself?

CrowdScience explores these questions with the help of experts from the fields of philosophy, mathematics and science: Dr Eleanor Knox, Dr Eugenia Cheng, Professor Lucie Green, Alex Bellos and Stefano Centineo.

Arts therapies appear to ease a host of brain disorders from Parkinson's to PTSD. But these treatments that rely on music, poetry or visual arts haven't been backed by rigorous scientific testing. Now, artists and brain scientists have launched a program to change that. NPR's brain correspondent Jon Hamilton tells us about an initiative called the NeuroArts Blueprint.

On December 31, 2021, The Joe Rogan Experience podcast on Spotify posted an episode with an interview with physician Dr. Robert Malone full of misinformation about the Covid-19 vaccine. This sparked outrage, a letter from a group of medical professionals, scientists and educators to Spotify and a series of creators pulling their content from the platform. Science Vs., a podcast produced by Gimlet Media which is owned by Spotify, decided to take a stand too.

Listen to the episodes of Science Vs discussed here:

Understanding how life survives in extreme Earth environments could point to ways life can survive on other worlds. Astrobiologist Morgan Cable talks to host Emily Kwong about how her missions here on Earth have guided two upcoming NASA missions in search for alien life, not in a far off galaxy, but here in our solar system. The Titan Dragonfly and the Europa Clipper missions will each explore an ocean world in our solar system, where scientists believe we could find life--life that may be unlike anything we've seen before. Today on Short Wave, life as we know it - and life as we don't know it.

Learn more about the search for life in our solar system in the new planetarium show Living Worlds, now at the California Academy of Sciences:

Over the last 24 hours, some of us Short Wavers celebrated Pi Day the only way we know how: eating some yummy pie and thinking math thoughts. Here on the show, many of us are math enthusiasts. But none of us claims to be a math perfectionist. We think there's at least as much joy and insight in the mistakes as there is in what we get right. It's a lesson we discussed in today's episode about Matt Parker's book, Humble Pi. It's an oldie but a goodie from our archives.We hope it inspires you to continue to celebrate pi and math everyday.
