Rank #2: Curiosity’s Search for Ancient Habitable Environments at Gale Crater, Mars .
4th Annual Lobanov-Rostovsky Lecture in Planetary Geology delivered by Professor John Grotzinger, Caltech, USA The Mars Science Laboratory rover, Curiosity, touched down on the surface of Mars on August 5, 2012. Curiosity was built to search and explore for habitable environments and has a lifetime of at least one Mars year (~23 months), and drive capability of at least 20 km. The MSL science payload can assess ancient habitability which requires the detection of former water, as well as a source of energy to fuel microbial metabolism, and key elements such carbon, sulfur, nitrogen, and phosphorous. The search for complex organic molecules is an additional goal and our general approach applies some of the practices that have functioned well in exploration for hydrocarbons on Earth. The selection of the Gale Crater exploration region was based on the recognition that it contained multiple and diverse objectives, ranked with different priorities, and thus increasing the chances of success that one of these might provide the correct combination of environmental factors to define a potentially habitable paleoenvironment. Another important factor in exploration risk reduction included mapping the landing ellipse ahead of landing so that no matter where the rover touched down, our first drive would take us in the direction of a science target deemed to have the greatest value as weighed against longer term objectives, and the risk of mobility failure. Within 8 months of landing we were able to confirm full mission success. This was based on the discovery of fine-grained sedimentary rocks, inferred to represent an ancient lake. These Fe-Mg-rich smectitic mudstones preserve evidence of an aqueous paleoenvironment that would have been suited to support a Martian biosphere founded on chemolithoautotrophy and characterized by neutral pH, low salinity, and variable redox states of both iron and sulfur species. The environment likely had a minimum duration of hundreds to tens of thousands of years. In the past year simple chlorobenzene and chloroalkane molecules were confirmed to exist within the mudstone. These results highlight the biological viability of fluvial-lacustrine environments in the ancient history of Mars and the value of robots in geologic exploration.
Science Underground is a two-minute podcast hosted by TED speaker and scientist Ainissa Ramirez. By the time you sip your coffee or eat your cereal, Science Underground explains a science topic in a fun and understandable way. The show explores a range of topics—some that are pulled right from the headlines, others are topics you’ve been wanting to know. Ainissa interviews tops scientists and translates their work in everyday language--arming you with science nuggets for the next lunch table chat, water cooler klatch, or cocktail party. Each week there is a separate topic that can be listened to before class or when you have a brief moment to spare. The ideas will give you much to think about long after the podcast is over.

Scientific principles, theory, and the role of key figures in the advancement of science.
Rank #1: Calculus.
Melvyn Bragg discusses the epic feud between Sir Isaac Newton and Gottfried Leibniz over who invented an astonishingly powerful new mathematical tool - calculus. Both claimed to have conceived it independently, but the argument soon descended into a bitter battle over priority, plagiarism and philosophy. Set against the backdrop of the Hanoverian succession to the English throne and the formation of the Royal Society, the fight pitted England against Europe, geometric notation against algebra. It was fundamental to the grounding of a mathematical system which is one of the keys to the modern world, allowing us to do everything from predicting the pressure building behind a dam to tracking the position of a space shuttle.Melvyn is joined by Simon Schaffer, Professor of History of Science at the University of Cambridge and Fellow of Darwin College; Patricia Fara, Senior Tutor at Clare College, University of Cambridge; and Jackie Stedall, Departmental Lecturer in History of Mathematics at the University of Oxford.
Rank #2: Black Holes.
Melvyn Bragg and guests discuss Black Holes. They are the dead collapsed ghosts of massive stars and they have an irresistible pull: their dark swirling, whirling, ever-hungry mass has fascinated thinkers as diverse as Edgar Allen Poe, Stephen Hawking and countless science fiction writers. When their ominous existence was first predicted by the Reverend John Mitchell in a paper to the Royal Society in 1783, nobody really knew what to make of the idea - they couldn’t be seen by any telescope. Although they were suggested by the eighteenth century Marquis de Laplace and their existence was proved on paper by the equations of Einstein’s General Theory of Relativity, it was not until 1970 that Cygnus X 1, the first black hole, was put on the astral map. What causes Black Holes? Do they play a role in the formation of galaxies and what have we learnt of their nature since we have found out where they are?With the Astronomer Royal - 2001 Sir Martin Rees, Professor of Physics and Astronomy at Cambridge University; Jocelyn Bell Burnell, Professor of Physics at The Open University; Professor Martin Ward, director of the X-Ray Astronomy Group at the University of Leicester.

Rank #1: EP128 Daily routines makeover: How to maximize your time at school so you can work less at home.
Join me today as I help one teacher make over her daily schedule so she can maximize her time in school and work less at home based on a coaching call that I conducted with a graduate of the 40 Hour Teacher Workweek Club. Have you ever wondered how time slips away from you and the entire day is gone? Listen in as I walk Amara, a 3/4 French Immersion teacher from Winnipeg, Manitoba, through each element of her non-instructional time and look for ways that she can streamline and simplify. As you listen in, I encourage you to ask yourself the same questions I’m asking Amara as you are going to be able to relate to her challenges because they’re common to almost all teachers.

Rank #2: S5EP14 How to respond to rude, disrespectful student attitudes (with Robyn Jackson).
Today we're going to talk about the little things students do that are rude, disrespectful, or just annoying. The things that don’t necessarily warrant some kind of consequence, but that you don’t want to let slide every time. How should a teacher respond to eye rolling, teeth sucking, muttering under the breath, and so on? What do we do about bad attitudes? I don’t want to settle for trite rehashed info, so I reached out to Robyn Jackson because I knew she could take this conversation to a deeper level. Robyn was a National Board Certified English teachers in Maryland, just outside of Washington DC, and has since been and administrator, adjunct professor, consultant, and speaker. She’s been championing equity, access, and rigor for over 15 years. Robyn is seriously one of my favorite experts in the education space, because she has a deeper understanding of human behavior and motivation than anyone else I know, and she always keeps it real. I’ve had the pleasure of seeing her speak in person a few times just hang on her every word--there’s so much good info there. She has this lovely way of uncovering the root problem and also sort of calling you out on your own mess instead of allowing blame-shifting. Grab a notepad when you listen to this one, because you’re going to want to take notes! Want to give your feedback on Season 5 of the podcast?

Rank #1: The Meteorite Hunter
Deep in Antarctica, a rookie meteorite hunter helps collect a mystery rock. Could it be a little piece of Mars? In Antarctica, the wind can tear a tent to pieces. During some storms, the gusts are so powerful, you can’t leave the safety of your shelter. It’s one of the many reasons why the alluring, icy continent of Antarctica is an unforgiving landscape for human explorers. “It’s incredibly beautiful, but it’s also incredibly dangerous,” says geologist Nina Lanza, who conducted research in the Miller Range in the central Transantarctic Mountains of Antarctica for about five weeks in December, 2015. “It’s not like Antarctica is out to get you, but it’s like you don’t matter at all. You are nothing out there.” Yet, this landscape—unfit for human habitation—is where Lanza and the Antarctic Search for Meteorites program (ANSMET) volunteers find themselves banded together. They are prospecting for meteorites. Embedded in the sparkling blue ice sheets of the Antarctic interior are scientifically precious stones that have fallen to Earth from space. Lanza is a rookie meteorite hunter, enduring the hostile conditions of the Antarctic for the first time—searching for little geologic fragments that reveal the history of our solar system. While most people associate Antarctica with penguins, in the Miller Range, there are no visible signs of life. There are no trees, animals, insects, or even birds in the sky. Being that isolated and alone is strange—it’s “very alien,” says Lanza. “You know the cold and the living outside part? That is easy compared to the mental part,” she says. “It’s almost hard to explain the level of isolation. Like we think we’ve all been isolated before, but for real, in the Miller Range, you are out there.”The luxurious ‘poo bucket’ at ANSMET camp.(Credit: Nina Lanza) In this dramatic, extreme environment, Lanza finds comfort in the familiar details of everyday life at the ANSMET camp. Amid the Antarctic’s wailing winds, you can hear the recognizable hiss of a camp stove. During the holidays, Lanza got everyone singing Christmas carols. And then there’s the ‘poo bucket’—complete with a comfortable styrofoam toilet seat, scented candles, and bathroom reading reminiscent of home (including the New Yorker and Entertainment Weekly). In the field, Nina documented these features of everyday life in detail, in pictures and voice recordings. “Everybody talks about how beautiful it is and you always see a million pictures of these grand vistas, but I’m like, ‘let’s talk about the less pretty stuff,’” says Lanza. Unless you make an effort to remind yourself, “you could almost forget that the poo bucket ever existed.” The work isn’t easy. The ANSMET field team can spend up to nine hours a day on their skidoos (Lanza’s skidoo, “Miss Kitty,” is covered with Hello Kitty stickers) combing ice sheets and flagging potential meteorites. The never-setting sun glares intensely on the stretches of glistening, blue ice. (Old, compressed, ice appears blue.) On a clear, cloudless day out in the field, the sky and ice sheets seem to meet in one continuous field of blue, says Lanza. “It’s almost like an artist’s conception of water rendered into glass or plastic,” she says about the ice. “It’s blue and it goes on forever.” The meteorite hunters concentrate their searches in these shimmering, blue ice areas, because these ice fields are gold mines for meteorites. When a meteorite impacts Antarctica, it becomes buried in snow. Over time as the snow compresses, the rock gets trapped in glacial ice. If that ice doesn’t break off and fall into the sea, Antarctic winds can eventually resurface that buried treasure. Over the last four decades, ANSMET scientists have collected over 20,000 rock specimens from the ice. And in December, 2015, Lanza thinks she may have helped strike gold in the form of a five-pound, grey rock. She and her colleagues will spend the next nine months wondering if this rock could be one of the most prized meteorites of all.

Rank #2: Born This Gay
At the turn of the 20th century, a German doctor sets out to prove that homosexuality is rooted in biology—but his research has consequences he never intended. In pre-Nazi Germany, a doctor named Magnus Hirschfeld sets out to take down Paragraph 175, a law against “unnatural fornication” between men. Hirschfeld’s plan is to scientifically prove that homosexuality is natural, and that lesbians and gay men might be born gay—but his idea ends up falling into the wrong hands. Party at the Institute for Sexual Science. Magnus Hirschfeld (second from right) is the one with the moustache and glasses. His partner Karl Giese is holding his hand. (United States Holocaust Memorial Museum) German students parade in front of the Institute for Sexual Research prior to their raid on the building. The students occupied and pillaged the Institute, then confiscated the Institute's books and periodicals for burning.(United States Holocaust Memorial Museum) German students and Nazi SA plunder the library of Dr. Magnus Hirschfeld. The materials were loaded onto trucks and carted away for burning. The public library of the Institute comprised approximately 10,000 mostly rare German and foreign books on the topics of sex and gender.

Rank #1: Moths, Alan Alda, Graveyard Lichens. Nov 1, 2019, Part 2
There are over 160,000 species of moths worldwide, and they come in all different shapes and sizes. For example, the Comet Moth, native to the rainforests of Madagascar, boasts vibrant red and yellow patterned wings, feathery antennae, and long swapping tails, thought to useful for distracting its bat predators. By comparison, most common North American moths seem boring and dull. While their butterfly relatives flit about the garden in daylight, moths are often found lurking around outside lamps at night. And they can be a nuisance—eating holes in your cashmere sweaters or natural fiber rugs. Even in popular culture they get a bad rap. We use terms like “moth-balled” to describe a cancelled project and “like a moth to flame” when we talk about a perilous situation. But do moths deserve the unflattering characterization of the mysterious, scaly-winged insect that haunts the night? Dr. David Lees, Curator of Lepidoptera at the Natural History Museum of London, certainly doesn’t think so. He joins Ira to set the record straight about moths by highlighting their astonishing diversity and usefulness. Actor and writer Alan Alda might be best known as Hawkeye Pierce in M*A*S*H, or as a familiar face from several Woody Allen films. But he also spent more than a decade interviewing scientists on Scientific American Frontiers, and later founded a center to teach scientists how to communicate better with the public—through improv. His latest project is hosting the podcast Clear + Vivid, where he’s interviewed a long list of public figures, from Adam Driver to Melinda Gates, and a wide variety of scientists like climate scientist Katharine Hayhoe and primatologist Frans de Waal. In this interview with Ira, he focuses on a few memorable moments in the podcast that illustrate how to talk about tough topics like climate change. A cemetery isn’t necessarily the first place that comes to mind when thinking about urban biodiversity and conservation, and, for a while, even ecologists wrote them off. But there’s a growing body of research that’s come together in recent years pointing to the value of these unexpected green spaces in protecting biodiversity, especially in cities where land is at a premium and green space is limited. Researchers even discovered a new beetle species at a cemetery in Brooklyn earlier this summer and spotted a rare salamander species in the same cemetery only a few years earlier. But it’s not just beetles and salamanders that take refuge in cemeteries. Lichen, which are an algae-fungi amalgamation, do too. Jessica Allen, assistant professor of biology at Eastern Washington University and an expert in New York City lichen, joins Ira to discuss the rare lichen that her research team found in a cemetery in the Bronx and why cemeteries are helping lichen to thrive in NYC.
Rank #2: Quantum Leaps, Cancer Drugs, Cat Cameras. June 7, 2019, Part 2
The “spooky physics” of the quantum world has long been marked by two key ideas: The idea of superposition, meaning that a quantum particle can exist in multiple states simultaneously, and the idea of randomness, meaning that it’s impossible to predict when certain quantum transitions will take place. Writing in the journal Nature, Zlatko Minev and colleagues report that they may be able to make the quantum behavior slightly less mysterious. Minev joins Ira to talk about the finding, and what new directions it might open up in quantum research. For patients whose cancer has metastasis, the options can be limited. While new drugs are being developed, they are often only approved for a specific subset or stage of cancer—sometimes even a specific age group. However, researchers are looking to expand on a pool of patients that can get these new drugs. Dr. Sara Hurvitz, the director of the Breast Cancer Research Program at UCLA, joins Ira to talk about how a drug that was approved for breast cancer in postmenopausal women may soon be available for younger patients. Plus, Dr. Neeraj Agarwal, the director of the Genitourinary Oncology Program, to talk about a new treatment option for patients with metastatic prostate cancer. If you want the real scoop on what your cat is doing while you’re away, researchers are studying that very question, using cat cameras. Our feline friends spend quite a lot of time outside of our line of sight, and we imagine them napping, bathing, playing, hunting. But that’s merely speculation. To get the data, researchers need to catch them in the act. Maren Huck, Senior Lecturer at the University of Derby in the UK, recently published a methodological study where she successfully tracked the movements of 16 outdoor domestic cats to find out what they were up to. She joins Ira to discuss the findings, which she published in the journal Applied Animal Behavior Science. Plus, cat behavior specialist and University California Davis Veterinary School researcher Mikel Delgado joins the conversation to talk more about catching cat behavior on camera, and what we can learn from recording their secret lives.
