The voting infrastructure is a vast network that includes voting machines, registration systems, e-poll books, and result reporting systems. This summer, the federal government put out a report that stated that hackers, possibly connected to Russia, targeted the election systems of twenty-one states. No changes in voter data were detected. How can we secure our voting from malicious hacks and technological errors? Lawrence Norden, Deputy Director of NYU’s Brennan Center's Democracy Program, and

Before the U.S. Food and Drug Administration was formed in 1906, you might have been more weary of pouring milk over your morning cereal. Milk could be spiked with formaldehyde, while pepper could contain coconut shells, charred rope or floor sweepings. In 1883, Dr. Harvey Washington Wiley, who was appointed chief chemist of the Federal Agriculture Department, began to investigate how manufacturers used additives and unhealthy practices in food—and pulled together “The Poison Squad.” Author Deborah

This week the fields of physics, chemistry, physiology, and medicine awarded its top scientists with its highest honor, the Nobel Prize. And this year, the annual celebration of scientific greatness was punctuated by a historic achievement: For the first time ever two female scientists won the award for both physics and chemistry, Dr. Donna Strickland and Dr. Frances Arnold. Dr. Arnold joins Ira to discuss her award and the legacy of female Nobel laureates. While most of us might think we’re logical

Yemen is gripped by civil war—and some experts say it could be the first of many “water wars” to come, as the planet grows hotter and drier. In This Is the Way the World Ends: How Droughts and Die-Offs, Heat Waves and Hurricanes Are Converging on America, Jeff Nesbit writes of the Yemeni conflict and many other geopolitical consequences of a warming world, including the precarious future of the Indus River, under the control of China, India and Pakistan, and why Saudi Arabia’s biggest dairy company

Back in December, the Trump administration announced reductions to two of Utah’s national monuments: Grand Staircase-Escalante, which runs from the Grand Canyon to Bryce Canyon National Park, and Bears Ears, newly established by the Obama administration just a year before. The reduction opened up nearly 2 million acres of previously protected federal land to fossil fuel and mineral exploitation, angering Native Americans, for whom the land is historically and spiritually significant, as well as

As a critical care doctor, Jessica Zitter has seen plenty of “Hail Mary” attempts to save dying patients go bad—attempts where doctors try interventions that don’t change the outcome, but do lead to more patient suffering. It’s left her distrustful of flashy medical technology and a culture that insists that more treatment is always better. But when a new patient goes into cardiac arrest, the case doesn’t play out the way Jessica expected. She finds herself fighting for hours to revive him—and

About five million years ago, the island of Kauai emerged from the ocean waves, and a new chain of island habitats was born, right in the middle of the Pacific. In those Hawaiian islands, birds would have found a multitude of microclimates, a lack of most predators, and a pretty safe spot to grow and evolve—which they did, diversifying into a wide range of species, each suited to a different lifestyle and habitat. But today Hawaii’s diverse birds are under attack by invasive mongooses, cats, rats

If you stood in southeastern Utah over 200 million years ago, you’d be overlooking the ocean. The landlocked state wasn’t quite the same landscape of scarlet plateaus and canyons you might see today, but a coastal desert where sand dunes butted up right against the sea. And it was home to some of the earliest dinosaurs. In this region of Utah, today known as Indian Creek in Bears Ears National Monument, the remains of dinosaur relatives, known as protodinosaurs or “dinosaur aunts and uncles,” are

Since the 1980s, Gerta Keller, professor of paleontology and geology at Princeton, has been speaking out against an idea most of us take as scientific gospel: That a giant rock from space killed the dinosaurs. Nice story, she says—but it’s just not true. Gerta's been shouted down and ostracized at conferences, but in three decades, she hasn’t backed down. And now, things might finally be coming around for Gerta’s theory. But is she right? Did something else kill the dinosaurs? Or is she just too

Climate change is increasing temperatures and causing heavier rainfalls across the country. Scientists are studying how these changes will affect different natural resources, including the soil ecosystem. For example, in Wisconsin, soil erosion is predicted to double by 2050 due to heavier rainfalls, according to a report by the Wisconsin Initiative on Climate Change Impacts. Agricultural scientist Andrea Basche talks about how soil formation and health is tied to climate. She joins microbiologist

Last month, California passed a bill ending the use of cash bail. Instead of waiting in jail or putting down a cash deposit to await trial at home, defendants are released after the pleadings. The catch? Not everyone gets this treatment. It’s not a judge who determines who should and shouldn’t be released; it’s an algorithm. Algorithms have also been used to figure out which incarcerated individuals should be released on parole. Mathematician Hannah Fry and computer scientist Suresh

Each spring, animals move from their winter grazing grounds in search of greener pastures. For birds, where and when to start that journey is based on genetics, and signals from stars, and magnetic fields from the earth. But for some larger mammals like sheep and moose, they’re not born knowing where to go. They need to learn a mental migratory map—and it’s often passed down from other herd members.

According to researchers, knowing more about a robot or bonding with it can make you hesitant to harm it. And if the bond between you and a robot is strong enough, you might even go out of your way to protect it.

The human brain contains an estimated 100 billion neurons. When those cells malfunction, the disrupted process can lead to schizophrenia, PTSD, and other disorders. In his book The Disordered Mind, Nobel Prize-winning neuropsychiatrist Eric Kandel looks at where the processes fault to give insight into how the brain works. According to Kandel, the understanding of these disorders offers a chance “to see how our individual experiences and behavior are rooted in the interaction of genes and

Worker ants keep the nest alive. They look for food, take care of the eggs, and dig all the tunnels. Fire ant colonies, for example, have hundreds of thousands of worker ants. You’d think traffic jams happen all the time. But they don’t! The majority of the ants aren’t working, according to a study published in Science this week from the Georgia Institute of Technology. They remain idle to stay out of the way, leaving only 30% of the ants to dig a new hole. The researchers also believe the dynamic
