The science of Unidentified Aerial Phenomena
28:05

Ever spotted a strange object in the sky? According to a recent report released by the U.S. government, nearly 150 aerial objects observed between 2004 and 2021 remain unidentified—with the exception of one large deflated balloon. The sightings of these objects, once called UFOs and now referred to as Unidentified Aerial Phenomena (UAP), can have a number of reasonable explanations. Cloud formations, Venus shining brightly in the night sky, or the occasional recon aircraft or government-led missile test can all be mistaken for a UAP. But what if there’s another explanation out there? Could extraterrestrial intelligence explain some sightings? To find out, Dr. Alok Patel explores the possibilities with an astrophysicist and a NASA engineer. Together, these space exploration and research innovators remind us that the truth is out there—we just need to look to science.

Using technology to cope with drought
27:58

As temperatures continue to rise this summer, the U.S. is experiencing increasingly worse drought conditions with more than 93% of land in seven Western states affected. Though this decades-long dry spell is concentrated in the Western part of the country, droughts have widespread consequences, affecting everything from our national food supply to water quality.

With the help of hydrologists and innovators on the ground and in the lab, Dr. Alok Patel learns about the traditional ecological knowledge of the Navajo Nation in the especially hard-hit Southwest. And he speaks with innovators applying advanced technology to agricultural practices, like drone surveillance and artificial intelligence, to prepare for and cope with drought.

The science of exercise—and getting back in the game
29:59

Hey folks, it’s been a minute. But now we’re back and breaking down the science behind the headlines. This week, we’re stretching it out and exploring the science of exercise and—after more than a year of unexpected interruption—getting back in the game. Dr. Alok Patel checks in with an expert in exercise physiology and an Olympic athlete, biomechanist, and chiropractor. Together, they talk about training under lockdown, what happens to the body and mind when taking time away from intense training, and how us amateurs can safely ease back into exercise—just in time to watch the 2021 Olympic games.

The science of positive motivation for the New Year
25:30

2020 is finally over. After the coronavirus pandemic and everything else the year's thrown our way, it's time to dust ourselves off and get ready for 2021. To do that, we need positive motivation (neurologically, that’s how our brains prepare to get things done). First, we hear from a neuroscientist on the science of becoming and staying motivated. Then, we have a special auditory treat. All season, host Alok Patel has asked NOVA Now guests which songs motivate them to do their work, whether that’s running COVID-19 tests in a hospital or conducting experiments in a lab. We took those songs and wrapped them up as a gift for you: a Nova Now Spotify playlist. Tune in for a taste of guests’ music picks and to revisit some of our most memorable moments from the year.

How the future of satellites might affect life on Earth
27:08

In 2020, the world celebrated two decades of continuous human presence aboard the International Space Station (ISS). As an orbiting laboratory that has provided astronauts with a view of Earth from outer space, the ISS may not seem very similar to other space innovations like CubeSats and NASA/USGS’s Landsat. But all of these devices are satellites: objects orbiting objects larger than themselves. Satellites can be natural (like the moon and planets, including Earth) or human-made (like the ISS). Joined by two experts in this outer-worldly technology, host Alok Patel explores how satellites have shaped our understanding of the modern world, including the Landsat program’s effort to create a space-based record of the surface of the Earth, and what lies ahead at the intersection of justice and space.

Covid vaccines are coming: What’s inside, and how and when you’ll get one
27:16

Pending FDA approval, safe and effective COVID-19 vaccines could reach the first wave of Americans in a matter of weeks. Manufacturers of leading vaccine candidates are releasing promising results from clinical trials, revealing that some experimental vaccines, including those from Pfizer and Moderna, are more than 90% effective against the coronavirus. But vaccine development alone will not end the pandemic; getting the distribution right is key. Host Alok Patel speaks with two immunization experts about the challenges of distribution at an unprecedented scale. Tune in to explore questions like: What are the differences between the first vaccine candidates? Who can expect to get vaccinated first and how much will it cost? And why do vaccines have to be kept so cold?

The future of food
30:40

Chew on this: Thanksgiving is around the corner and November is Native American Heritage Month. In honor of celebrating nature’s bounty, Host Alok Patel considers the past, present, and future of food. He digs into the world of food science with the resident science guy at America’s Test Kitchen, speaks with an Indigenous community cook, educator, and community organizer about food sovereignty and equitable food systems, and checks in with a scientist who is genetically engineering plants to photosynthesize more efficiently to increase crop yields.

The statistical science behind polling
21:04

With so much uncertainty on the eve of the U.S. presidential election, one place we look for clarity is in the numbers. Pollsters learned valuable lessons from the 2016 election results that they’ve applied in the current election cycle to try to yield more accurate predictions. Host Alok Patel interviews a pollster and a statistician, delving into a brief history of political polling in the U.S, what went wrong in 2016, and how statistical concepts like data weighting and margin of error make all the difference in the accuracy of the poll.

The science of fear
31:26

In a year that’s felt like a never-ending horror movie, some might actually find relief in watching thrillers on-screen this Halloween. But why is it that some people love all things spooky on screen while others can only watch through parted fingers?  What makes horror films so scary yet so alluring? And does our fascination with horror media actually help us cope with the horrors of real life? Host Alok Patel zeros in on the science of fear, enlisting the expert guidance of a horror researcher, a neuroscientist, and the Emmy-winning Foley artist behind the tantalizing and terrorizing sounds in movies and shows like Invisible Man and Monsterland.

Science in the courtroom
29:14

With confirmation hearings set to begin for Judge Amy Coney Barrett to join the Supreme Court, we ask the question that senators probably won’t: Do judges also need to be scientists? Science may not be the first thing that comes to mind when thinking of the U.S. court system, but everything from criminal cases’ forensic evidence to intellectual property disputes involve it. Host Alok Patel goes straight to the source for answers, speaking with a sitting federal judge and a lawyer who has worked on many Supreme Court cases.

Rising health risks from West Coast wildfires
31:26

It's wildfire season—and something about this year is especially sinister. West Coasters experienced days of hazy orange skies in early September as a result of the burning wildfires. As COVID-19 still looms, threatening our respiratory systems, now too does the smoke in the air. What is this smoke made of, and how does breathing it in affect our lungs and bodies? To find out, Host Alok Patel speaks with an atmospheric scientist, a pulmonologist, and a pair of veteran engineers who are experts in effective face masks to learn about the composition of wildfire smoke, what that smoke does to our lungs and bodies, and what we can do to protect ourselves.

COVID meets CRISPR
27:38

Many agree that we need a fast, accurate, and easy COVID-19 test—yet none of the commonly used diagnostic technologies have been able to meet that need. Enter CRISPR, a gene-editing tool that can also be used to identify viruses. Host Alok Patel follows the story of the two scientists who first discovered this potential for battling the coronavirus, and the biotech company that hopes to use it to revolutionize modern diagnostics.

The hidden science of mail-in voting
28:25

With a presidential election rapidly approaching and no indication that the COVID-19 pandemic is going anywhere, a record number of people will likely vote by mail. But what happens when we send that ballot off in the mail? And how do we make sure it gets counted? With the help of a former FBI agent-turned-forensic document examiner and a ballot tracking software insider, host Alok Patel follows the journey of a mail-in ballot from your kitchen counter to the election office.
