Bumblebees and honeybees are two species of bees that form colonies. The colonies of bumblebees are smaller compared to their honeybee cousins, who’s hives can house tens of thousands of individuals. But both of these colonies have complicated compositions and structures that help them thrive. For bumblebees, recent studies showed that colonies located in urban areas may actually be more successful than nests located in agricultural areas. Plus, how do bees pick a new queen?

Whales are majestic, awe-inspiring animals. Some species can reach up to 150 tons and take in a living room-sized volume of water in one gulp. They can even dive thousands of feet into the ocean while holding their breath all the way down. It’s hard to imagine that the earliest ancestors of these graceful creatures of the deep were four-legged dog-like animals that lived on land. In his book Spying on Whales: The Past, Present, and Future of Earth’s Most Awesome Creatures, paleontologist Nick

Math isn’t often thought of as a tool for social justice. But mathematical thinking can help us understand what’s going on in society too, says mathematician Eugenia Cheng. For example, abstract math can be used to examine the power structures between men and women, or white and black people, and to more clearly define the relationships and power differentials at play. At our live event at the Harris Theater in Chicago, we called on WBEZ’s Curious City to help us out. Chicago resident Devin

Last week, the National Institutes of Health cancelled a $100 million study of alcohol and health after an internal investigation found “early and frequent” engagement with none other than the alcohol industry, to an extent that would “cast doubt” on the scientific results. But prior to the cancellation, the research was setting out to answer an ongoing question about alcohol and our health: Are moderate drinkers actually better off than nondrinkers? Study after study has found that light or

Over less than a decade, the gene-editing technique known as CRISPR-Cas9 has taken the biology world by storm. But two new studies indicate that there could be a downside to the CRISPR approach. Did you know a blue jay’s feathers and a butterfly’s wings aren’t actually blue? Neither are your blue eyes. From the colors we see in flowers and birds, to the hues we use in art and decoration, there’s more than one way to make a rainbow—and it all starts with molecules and structures that are too small to

Like a kraken rising from the depths (or a cuttlefish emerging from the sand), Cephalopod Week is back! Every year, Science Friday spends a week honoring the mighty, clever, mysterious cephalopod. This year, Field Museum curator Janet Voight joins Ira and SciFri’s chief cephalopod cheerleader Brandon Echter to talk about the unusual and brainy behaviors of these creatures—including a squid that uses bioluminescent bacteria to camouflage itself—and whether cephalopods could someday become a model

In 1832, less than a year into the first voyage of the Beagle, Charles Darwin found a beetle in Argentina. Turns out, discovering new species in the depths of museum archives is not so uncommon. 180 years later, an entomologist who happened to specialize in rove beetles requested an assortment of samples from London’s Natural History Museum. There, among 24 pinned beetle specimens, was Darwin’s rove beetle. Dozens of such tales of are told by biologist and author Christopher Kemp in his new book The

Planets, stars, and physical “stuff” make up a tiny fraction of the universe. Most of the universe's mass is instead invisible dark matter, which makes itself known not by luminance, but by its gravitational influence on the cosmos. The motions of galaxies and stars require dark matter to be explained. Yet despite decades of searching and millions of dollars spent, physicists still haven't been able to track down a dark matter particle. In this segment, physicists Jodi Cooley and Flip Tanedo, and

The deep sea is the largest habitat on Earth, but it’s also one of the least understood. As mining companies eye the mineral resources of the deep sea—from oil and gas, to metal deposits—marine biologists like London’s Natural History Museum’s Diva Amon are working to discover and describe as much of the deep sea as they can. Amon has been on dozens of expeditions to sea, where she’s helped characterize ecosystems and discover new species all over the world. And she says we still don’t know enough

This year’s midterm elections have seen an upswing in the number of scientists running for office. There are approximately 60 candidates with STEM backgrounds in the races for federal offices, and 200 for state positions, according to 314 Action, an advocacy organization that helps scientists run for office. But why would a scientist want to leave the lab for the Hill? According to volcanologist and Congressional candidate Jess Phoenix, “Science by definition is political because the biggest funder

In his latest book, How to Change Your Mind, Michael Pollan writes of his own consciousness-expanding experiments with psychedelic drugs like LSD and psilocybin, and he makes the case for why shaking up the brain’s old habits could be therapeutic for people facing addiction, depression, or death. Pollan and psychedelics researcher Robin Carhart-Harris discuss the neuroscience of consciousness, and how psychedelic drugs may alter the algorithms and habits our brains use to make sense of the

In HBO’s series Westworld, human-like robots populate a theme park where human guests can have violent, gory adventures in the Wild West without the repercussions. The robots are so lifelike that they fool the visitors and themselves. They bleed, die, grieve, and love—thinking themselves human. But as Westworld’s robots grow increasingly independent of their repetitive, programmed loops, the show incites viewers to question whether AI can truly be autonomous or conscious—and who in this story

How do you think about time? Most people experience it as Newton described it—as something that passes independent of other events, that’s the same for everyone, and moves in a straight line. Still, others have come to embrace Einstein’s view that time instead forms a matrix with space and acts like as a substance in which we are submerged. But physicist and author Carlo Rovelli has an even different approach to time. He’s working on a way to quantify gravity in which time doesn’t exist. An adult

Hawaii’s Kilauea volcano—located on the Big Island—has been continuously erupting for the past 30 years. But on May 3, magma began spewing through fissures in the Puna district, forcing nearly 2,000 residents to flee. Reporter Ku`uwehi Hiraishi of Hawaii Public Radio spoke to residents in the area of these 15 fissures and describes what type of evacuation efforts have been happening on the ground.

Genetic testing sites are nothing new. They’ve grown enough in popularity over the past decade that the idea of spitting into a tube and sending it in the mail to a website to find out more about your family tree—or even your risk of certain inherited diseases—doesn’t seem all that strange to most people. But the case of the Golden State Killer has brought to light many questions about the direct-to-consumer genetic testing market that still need answering. Dr. Amy McGuire, professor of biomedical

In July of 2015, the world was stunned to learn that Pluto, a tiny, distant dot that some didn’t even consider a planet, was a dynamic, complex, and beautiful world. But for scientists in pursuit of Pluto’s secrets since the late 1980s, it was a long wait. The mission faced political hurdles, budget battles, technical challenges, and near-disaster even as it was days away from speeding past Pluto.

When winter comes, animals have several options for survival. They can leave their habitats entirely for warmer environments, search for a cozy cave, or even find insulation under a toasty snowbank. And if you’re a wood frog in chilly Ohio or Alaska, or the larvae of a certain wingless midge in Antarctica, you might also just stay put, and freeze solid until the sun returns. But to survive such extreme low temperatures, the bodies of these animals have made some special adaptations: sugars that act

It’s not uncommon these days to hear scientists and journalists say that our planet is experiencing record-setting temperatures due to climate change. But they’re talking about a small part of Earth’s history—human history. The story of the earth’s climate contains much more than what human beings have recorded. In their new book, Weather: An Illustrated History, longtime climate reporter Andrew Revkin and co-author Lisa Mechaley track the incredible range of climate history. They condense that
