The First Interstellar Object Detected by Humans
The first interstellar object detected by humans passed through our solar system in 2017. It was 300 feet long oblong and failed to conform to the expectations of either an asteroid or a comet. Now there is a paper out where some scientists say that they think a mua mua was probably a comet all along.
The Latest IPCC Report Is Full Of Warnings—And Hope
It’s that time of year: another IPCC report has hit the presses. These reports from the Intergovernmental Panel on Climate Change are like a check up—to let us know how we’re doing on the climate front and what Earth’s future is projected to look like. And to no one’s surprise, this year’s report is full of warnings. But also, it has a lot of room for hope.
Maggie Koerth, senior science writer at FiveThirtyEight, joins guest host Charles Bergquist to talk more about the report and other science news of the week. They chat about a 3D printed rocket that didn’t quite make it to space, the mysterious Oumuamua space object, the rise of dangerous fungal infections in the U.S., why researchers are so excited about figuring out Beethoven’s cause of death, and—of course—new research about octopuses’ brain waves.
An Underwater Volcano Off The Oregon Coast Sheds Light On Eruptions
A thick blue-white haze envelops the Research Vessel Thompson as it floats 250 miles off the Oregon coast. Akel Kevis-Stirling’s orange life vest and blue hardhat are vivid pops of color in the fog. “You guys ready to go?” he calls into his radio. The person on the other end crackles an affirmative. “Copy that,” he says and looks up across the rear deck of the research ship. “Alright, straps!”
The crew of the ROV Jason jumps into action, removing the straps that secure the cube-shaped submarine to the deck. The remotely-operated sub, with a base the size of a queen mattress, is loaded with scientific instruments it will carry down to the seafloor. Kevis-Stirling gets final permission from the Thompson’s bridge for the launch. “Ok, here we go. Jason coming up and over the side,” he calls. “Take it away Tito!” The crane operator, Tito Callasius, lifts the submarine and swings it over the side of the ship into the water. A plume of fine bubbles rises through the waves as Jason starts its mile-long descent to the Axial Seamount, a deep-sea volcano that’s erupted three times in the past 25 years.

March Mammal Madness Wants To Hear You Roar
When mid-March rolls around, your news online—and maybe your conversations with friends and colleagues—can sometimes get taken over by discussions about the tournament. From debating your bracket selections to conversations about last night’s matchup, or celebrating big upsets and debating whether this is finally the year the bat-eared fox goes all the way, it can feel all-consuming.
March Mammal Madness is an exercise in science communication involving a 64-animal bracket and nightly simulated combat matchups between animals—where the outcomes are determined by chance and specific species traits found in the scientific literature. This is the 10th year of the tournament, which this month has some 650,000 students around the world predicting battle outcomes on the road to the Elite Trait, the Final Roar, and the championship match.
Dr. Katie Hinde, a biological anthropologist in the School of Human Evolution and Social Change at Arizona State University, and ringleader of March Mammal Madness, joins SciFri’s Charles Bergquist to talk about the keys to success in the tournament. Want to participate yourself? It’s not too late—you can find the tournament bracket and more information about March Mammal Madness on the ASU Libraries site.
Listen To The Ethereal Sounds Of Space
You’ve probably heard that if you scream in space, no one will hear a thing. Space is a vacuum, so sound waves don’t have anything to bounce off of. But that doesn’t necessarily mean that space is silent. A team of researchers are taking data from a variety of telescopes and assigning them sounds, creating song-length sonifications of beloved space structures like black holes, nebulas, galaxies, and beyond.
The album, called “Universal Harmonies” aims to bring galaxies to life and allow more people, such as those who are blind and low-vision, to engage with outer space. Guest host Flora Lichtman talks with two of the scientists behind “Universal Harmonies,” Dr. Kimberly Arcand, visualization scientist at NASA’s Chandra X-ray Observatory, and Dr. Matt Russo, astrophysicist and musician at the University of Toronto.
