Turkey is the usual centerpiece of the Thanksgiving dinner, but it's all too easy to end up with a dry, tough, flavorless bird. For NPR science correspondent Maria Godoy, it got so bad that several years ago, her family decided to abandon the turkey tradition altogether. Can science help her make a better bird this year? That's what she hopes as she seeks expert advice from food science writers and cookbook authors Nik Sharma and Kenji López-Alt.

A new exhibit in Washington, DC, mixes science and technology for an immersive art experience — taking visitors not to a distant land, but into their brains. This installation is a partnership between the Society for Neuroscience and technology-based art space, ARTECHOUSE. Producer Thomas Lu talks to neuroscientist John Morrison and chief creative officer Sandro Kereselidze about the "Life of a Neuron."

Up to 8 percent of deer sampled in studies in the US were found to be infected with the SARS-Cov-2 Virus. Suresh Kuchipudi from the Department of Veterinary and Biomedical Sciences at Penn State University in the US says what they are seeing is a mixture of human to deer and deer to deer transmission of the virus. There is concern that its presence in animal reservoirs could lead to a new form of the virus emerging.

Tropical forests and spread of zoonotic diseases And as the Cop26 meeting in Glasgow draws to a close we ask how global policy on climate will impact the spread of zoonotic disease. Spill over of possible pandemic pathogens from animals to humans occurs with the destruction of tropical forests in particular and can expose people to previously unknown zoonotic diseases such as Covid 19.

Aaron Bernstein from the Coalition to Prevent Pandemics at the Source says healthcare initiatives designed to reduce the potential spread of such diseases need to be designed to work in tandem with conservation and climate change impact reduction initiatives, essentially tackling both problems simultaneously.

LED lighting Researchers in South Africa are looking into ways of making LED lighting both cheaper and more efficient. This should help reduce energy consumption, a prerequisite for effective policy on climate change.

In addition, as Professor Odireleng Martin Ntwaeaborwa tells us, the technology now has many applications in places where access to electricity is limited, including South Africa which currently has regular power outages.

Personalised medicine And personalised medicine based on our genes took a further step forward this week. Richard Scott, Chief Medical Officer for Genomics England discusses new findings which reveal the genetic basis for a range or rare diseases.

And, Concrete is the most widely used substance on earth after water. It’s quite literally the foundation of the modern world, and no wonder - it’s strong, cheap, and mouldable into nearly any shape.

But these benefits come at a cost: concrete production is responsible for around 8% of global CO2 emissions - that’s around three times more than the aviation industry.

Concrete might not look pretty, but given its carbon footprint, should we be more careful about how we use it? And rather than throwing waste into landfill, could we recycle it instead? That’s what Crowdscience listener Catherine wants to know.

To investigate, Marnie Chesterton and Anand Jagatia learn more about what makes concrete such a brilliant and versatile material. It’s down to the chemistry of how cement dries – which, it turns out, is anything but boring. They find out how the stuff is made, and why that produces so much carbon. And they hear about some ingenious projects to repurpose demolition waste – including creating underwater habitats for marine life, and using 3D printers to turn crushed concrete into street furniture.

It's been 150 years since the first article was published about the molecule key to life as we know it — DNA. With help from researcher Pravrutha Raman, Short Wave producer Berly McCoy explains how DNA is stored in our cells and why the iconic double helix shape isn't what you'd see if you peeked inside your cells right now.

A coalition of wealthier countries have promised that they'll provide $100 billion each year to help developing countries tackle climate change. So far, most haven't delivered on their promises, and it's a huge point of contention in the talks in Glasgow right now.

Today on the show, NPR climate correspondent Lauren Sommer reports on how it looks when one country does get help, and how much more is needed for climate equity.

In the first week of COP26, the UN climate conference, world leaders took to the podium to talk about what their countries are going to do to fight climate change. They made big pledges, but protestors in the streets call their promises "greenwashing" and are calling for more action.

Joining the show from Glasgow, Scotland, NPR science correspondent, Dan Charles, talks about how the conference is going. Will the diplomats follow the science on climate change? And will the nations of the world follow through on their pledges to cut greenhouse gas emissions?
