[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom](https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

The problem of climate change is a significant one, but What If We Get It Right? reminds us that with passion and ingenuity, there is so much we can accomplish.”—Roxane Gay “This book had me at its title. Through a collection of thoughtful essays and interviews, Johnson explores the possibility of getting it right with a visionary group of environmental leaders, activists and other big thinkers working on the front lines. Johnson, who has become a prominent voice on climate solutions, reminds us that there is also joy in working toward a future where we can all thrive.”—Los Angeles Times “This is the book we’ve been waiting for—a brilliant mix of creativity and wisdom that feels like we’re eavesdropping on intimate conversations with the world’s most brilliant change-makers. In What If We Get It Right?, Johnson weaves together art, poetry, and expert interviews into a deeply human exploration of the interconnected challenges we face. The result is a vision of a future filled with joy and possibility, where fixing one problem helps us solve many more.”—Katharine Hayhoe, climate scientist, author, and UN Champion of the Earth “An optimistic bent and eager embrace of solutions… these conversations are as much about ‘getting it right’ as they are about what we are currently getting wrong. Johnson is a top-notch interviewer, and her guests are insightful and candid.”—Scientific American “An entirely credible (and entirely enchanting) voice… Ayana Johnson is no Pollyanna. She’s a hard-nosed and extremely competent scientist who has not shied for a minute from facing the hard truths.”—Bill McKibben “Rigorous, elucidating, and hopeful in the most catalytic sense, this volume will stiffen your political will and open your mind and heart. It could arrive at no better moment.”—Rebecca Traister, bestselling author and writer for New York magazine “I believe that this is a book that the young among us have been waiting for. It is certainly the reset that we as societies and as elders owe to coming generations of humanity—and to our magnificent natural world.”—Krista Tippett, Peabody Award-winning broadcaster, a National Humanities Medalist, and a New York Times bestselling author “The climate crisis is terrifying, but also exhilarating—exhilarating because spectacular new ideas, approaches, and values are arising to address the terrifying stuff… Ayana Elizabeth Johnson's fantastic new anthology lets you listen to dozens of them.”—Rebecca Solnit, author, feminist, environmentalist “Critically, What If We Get It Right? reminds us of the most important solution of all: protecting and restoring nature, the magic of photosynthesis and water cycle. If you need a kick in the pants to roll up your sleeves on climate solutions, this book is for you.”—Yvon Chouinard, founder of Patagonia “If you are enamored with possibility, as I am, let the perspectives gathered in these pages fill you up and propel you on. Ayana Elizabeth Johnson has prepared a genuine feast for us. Savor every ‘what if’ for our shared future.”—Dr. Katharine K. Wilkinson, co-editor of All We Can Save and lead writer of Drawdown ### About the Author Dr. Ayana Elizabeth Johnson is a marine biologist, policy expert, writer, and Brooklyn native.

What Happened to the Energy Transition? To land a ship on a moving target, the moon, for example, from a moving object, the earth, requires an enormous attention to facts and a mastery of detail. Getting any of these wrong can lead to disaster. Climate science tells us we must transition to a zero carbon society—and fast. But are climate-deniers the only obstacle to that transition? We will discuss the work of economic historian Jean-Baptise Fressoz who suggests that even as we move to solar panels and electric vehicles, rather than “transitioning” to a zero carbon world we will continue to consume more, and more, and more and produce more carbon dioxide. Is there a way out of here? As harrowing as it sounds, its best to pay attention to the facts and master the details so we can discuss real solutions. Perhaps, a solution that depends on a transition in our ethical thinking.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“What Digital Detectives Find,”** on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives) .] What happens when you delete digital data such as a picture, video, or email message? The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever. Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years. You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered. Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not. Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: A digital forensics examiner works with evidence in the FBI’s New Jersey Regional Computer Forensics Laboratory (FBI photo).
