The South Pole’s IceCube detector catches a ghostly particle from deep space, and how rice knows to grow when submerged

A detection of a single neutrino at the 1-square-kilometer IceCube detector in Antarctica may signal the beginning of “neutrino astronomy.” The neutral, almost massless particle left its trail of debris in the ice last September, and its source was picked out of the sky by the Fermi Gamma-ray Space Telescope soon thereafter. Science News Writer Daniel Clery joins host Sarah Crespi to discuss the blazar fingered as the source and how neutrinos from this gigantic matter-gobbling black hole could help astronomers learn more about mysterious high-energy cosmic rays that occasionally shriek toward Earth. Read the research. Sarah also talks with Cornell University’s Susan McCouch about her team’s work on deep-water rice. Rice can survive flooding by fast internodal growth—basically a quick growth spurt that raises its leaves above water. But this growth only occurs in prolonged, deep flooding.

Sending flocks of tiny satellites out past Earth orbit and solving the irrigation efficiency paradox

Small satellites—about the size of a briefcase—have been hitching rides on rockets to lower Earth orbit for decades. Now, because of their low cost and ease of launching, governments and private companies are looking to expand the range of these “sate-lites” deeper into space. Host Sarah Crespi talks with Deputy News Editor Eric Hand about the mods and missions in store for so-called CubeSats. And our newest podcast producer Meagan Cantwell interviews Quentin Grafton of Australian National University in Canberra and Brad Udall of Colorado State University in Fort Collins about something called the “irrigation efficiency paradox.” As freshwater supplies dry up around the world, policymakers and farmers have been quick to try to make up the difference by improving irrigation, a notorious water waster. It turns out that both human behavior and the difficulty of water measurement are plaguing water conservation efforts in agriculture. For example, when farms find they are using less water, they tend to plant ever-more-water-intensive crops. Now, researchers are trying to get the message out about the behavioral component of this issue and tackle the measurement problem, using cheap remote-sensing technology, but with water scarcity looming ahead, we have to act soon.

<i>Science</i> and <i>Nature</i> get their social science studies replicated—or not, the mechanisms behind human-induced earthquakes, and the taboo of claiming causality in science

A new project out of the Center for Open Science in Charlottesville, Virginia, found that of all the experimental social science papers published in Science and Nature from 2010–15, 62% successfully replicated, even when larger sample sizes were used. What does this say about peer review? Host Sarah Crespi talks with Staff Writer Kelly Servick about how this project stacks up against similar replication efforts, and whether we can achieve similar results by merely asking people to guess whether a study can be replicated. Podcast producer Meagan Cantwell interviews Emily Brodsky of the University of California, Santa Cruz, about her research report examining why earthquakes occur as far as 10 kilometers from wastewater injection and fracking sites. Emily discusses why the well-established mechanism for human-induced earthquakes doesn’t explain this distance, and how these findings may influence where we place injection wells in the future. In this month’s book podcast, Jen Golbeck interviews Judea Pearl and Dana McKenzie, authors of The Book of Why: The New Science of Cause and Effect.

Should we prioritize which endangered species to save, and why were chemists baffled by soot for so long?

We are in the middle of what some scientists are calling the sixth mass extinction and not all at-risk species can be saved. That’s causing some conservationists to say we need to start thinking about “species triage.” Meagan Cantwell interviews freelance journalist Warren Cornwall about his story on weighing the costs of saving Canada’s endangered caribou and the debate among conservationists on new approaches to conservation. And host Sarah Crespi interviews Hope Michelsen, a staff scientist at Sandia National Laboratories in Livermore, California, about mysterious origins of soot. The black dust has been around since fire itself, but researchers never knew how the high-energy environment of a flame can produce it—until now.

The youngest sex chromosomes on the block, and how to test a Zika vaccine without Zika cases

Strawberries had both male and female parts, like most plants, until several million years ago. This may seem like a long time ago, but it actually means strawberries have some of the youngest sex chromosomes around. What are the advantages of splitting a species into two sexes? Host Sarah Crespi interviews freelance journalist Carol Cruzan Morton about her story on scientists’ journey to understanding the strawberry’s sexual awakening. In 2016, experimental Zika vaccines were swiftly developed in response to the emergence of serious birth defects in the babies of infected woman. Two years after the height of Zika cases, there’s so little spread of the virus in the Americas that it has stymied vaccine trials. Researchers hope to overcome this hurdle with “human challenge experiments”—vaccinating people, then intentionally infecting them with Zika to see whether they’re protected from the virus. Meagan Cantwell talks with staff writer Jon Cohen about his news story that highlights the risks and rewards of human challenge experiments. This week’s episode was edited by Podigy.

Mutant cells in the esophagus, and protecting farmers from dangerous pesticide exposure

As you age, your cells divide over and over again, leading to minute changes in their genomes. New research reveals that in the lining of the esophagus, mutant cells run rampant, fighting for dominance over normal cells. But they do this without causing any detectable damage or cancer. Host Sarah Crespi talks to Phil Jones, a professor of cancer development at the University of Cambridge in the United Kingdom, about what these genome changes can tell us about aging and cancer, and how some of the mutations might be good for you. Most Western farmers apply their pesticides using drones and machinery, but in less developed countries, organophosphate pesticides are applied by hand, resulting in myriad health issues from direct exposure to these neurotoxic chemicals. Host Meagan Cantwell speaks with Praveen Vemula, a research investigator at the Institute for Stem Cell Biology and Regenerative Medicine in Bengaluru, India, about his latest solution—a cost-effective gel that can be applied to the skin to limit pesticide-related toxicity and mortality.

How the appendix could hold the keys to Parkinson’s disease, and materials scientists mimic nature

For a long time, Parkinson’s disease was thought to be merely a disorder of the nervous system. But in the past decade researchers have started to look elsewhere in the body for clues to this debilitating disease—particularly in the gut. Host Meagan Cantwell talks with Viviane Labrie of the Van Andel Institute in Grand Rapids, Michigan, about new research suggesting people without their appendixes have a reduced risk of Parkinson’s. Labrie also describes the possible mechanism behind this connection. And host Sarah Crespi talks with Peter Fratzl of the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, about what materials scientists can learn from nature. The natural world might not produce innovations like carbon nanotubes, but evolution has forged innumerable materials from very limited resources—mostly sugars, proteins, and minerals. Fratzl discusses how plants make time-release seedpods that are triggered by nothing but fire and rain, the amazing suckerin protein that comprises squid teeth, and how cicadas make their transparent, self-cleaning wings from simple building blocks. Fratzl’s review is part of a special section in Science on composite materials.

Measuring earthquake damage with cellphone sensors and determining the height of the ancient Tibetan Plateau

In the wake of a devastating earthquake, assessing the extent of damage to infrastructure is time consuming—now, a cheap sensor system based on the accelerometers in cellphones could expedite this process. Host Sarah Crespi talks with Contributing Correspondent Lizzie Wade about how these sensor systems work and how they might assist communities after an earthquake. In another Earth-shaking study, scientists have downgraded the height of the ancient Tibetan Plateau. Most reconstructions estimate that the “rooftop of the world” reached its current height of 4500 meters about 40 million years ago, but a new study suggests it was a mere 3000 meters high during this period.
