Computer Models Aid Scientific Discovery

8232When things are too big, too small or impossible to manipulate safely, scientists turn to computer models to reproduce the behavior of natural and man-made systems.

Lawrence Livermore National Laboratory’s popular series, Field Trip in the Lab, returns with four new lectures that look at research enabled by computational modeling. Each lecture highlights cutting-edge science presented by leading Lab researchers who are joined by master high school science teachers.

This year’s topics include exploring nature via computer simulation; fusion modeling; menacing microbes; and simulating the human heart on the world’s fastest supercomputer.

1761Computer Simulations: Exploring Nature with a Computer
Computer simulation reproduces the behavior of natural and man-made systems to help us understand, predict, and communicate. Vic Castillo, a research engineer at the Lawrence Livermore National Laboratory, shows how computer simulation is used by LLNL scientists.

1761Fusion Modeling: Using Big Computers to Understand One of the Universes Biggest Secrets
Postdoctoral Fellow Frederico Fiuza discusses the challenges associated with fusion modeling, and how the outstanding computational resources and advanced computer graphics at the Lawrence Livermore National Laboratory help us to create a miniature Sun on Earth.

1761Menacing Microbes: Protein Models Reveal Secrets
Protein modeling is a computational tool that researchers use to see microbial proteins. Using LLNL’s high performance computational capabilities, 3D models are created of microbial proteins, providing visual tools to expose microbial secrets.

1761The Cardioid Project: Simulating the Human Heart on the World’s Fastest Supercomputer
Computational physicist David Richard describes how to build a computer model of a human heart, starting from an individual cell and then using data from an actual person to create a realistic representation of a beating heart.

Lectures and demonstrations are targeted to middle and high school students which makes them perfect for anyone curious about the amazing work made possible by fast computers with substantial calculation power.

The University of California is a partner in Lawrence Livermore National Security, which manages Lawrence Livermore National Laboratory, a premier research and development institution for science and technology.

Sharks Without Borders: A Binational Effort to Study and Conserve Threatened Shark Species

8232Sharks have been around, essentially unchanged, for 400 million years. Their size, power, and massive jaws fill us with terror and fascination. And even though sharks kill fewer people than dogs each year, media coverage and movies of shark attacks have portrayed them as insatiable killing machines.

They may rule the ocean, but sharks are vulnerable. They grow slowly, produce few young, and are exceptionally susceptible to overfishing. Sharks are being depleted faster than they can reproduce. This threatens the stability of marine ecosystems around the world. A healthy and abundant ocean depends on predators like sharks keeping ecosystems balanced.

Sharks migrating between California and Baja California, Mexico, are threatened by commercial fishing activity in both countries. Join Scripps shark expert Dan Cartamil as he explores the ecology and behaviors of these fascinating animals, and discusses the issues relevant to the sustainability of our local shark populations.

Barry Scheck on Justice, the Innocence Project, and OJ Simpson

27760As co-founder of the Innocence Project, Barry Scheck has dedicated his career to exonerating the wrongfully convicted by using DNA evidence as well as reforming the criminal justice system as a whole. He also had a front row seat to one of the biggest trials of our time as a member of OJ Simpson’s defense team.

Watch In Defense of the Innocent – Legally Speaking as Scheck discusses the victories of the Innocence Project as well as the controversies he has faced.

Eating For Health (and Pleasure): The UCSF Guide to Good Nutrition

8232Healthy eating is not about strict dietary limitations, staying unrealistically thin, or depriving yourself of foods you love. Rather, it’s about feeling good, having more energy, and sustaining your mental disposition. If you feel overwhelmed by all the conflicting nutrition and diet advice out there, you are not alone.

UCSF Professor of Medicine Dr. Robert Baron and Registered Dietician and Diabetes Educator Katie Ferraro discuss eating healthy in this series from UCSF, Eating for Health (and Pleasure): The UCSF Guide to Good Nutrition.

8232How Do We Know What to Eat, Drink (and Take)?
Dr. Baron addresses this often perplexing question. He explains what you can do to improve your diet, as well as what supplements you should — and should NOT — be taking. You may be surprised at the evidence.

8232Dietary Guidelines: From Pyramid to Plate
65% of the world’s population live in countries where obesity kills more people than those who are underweight. Katie Ferraro, takes us through the history of the food pyramid and how to judge what to put on your plate to maintain healthy weight.

8232Dietary Fats: The Good, the Bad, the Ugly
Katie Ferraro explains a healthy person on 2,000 calorie diet per day should strive for 65 grams total fat, less than 20 grams saturated fat, zero grams trans fat and under 200 milligrams of dietary cholesterol. Learn more about each type of fat and how to identify which is in what food.

8232Understanding Obesity
Dr. Baron explains the prevalence of obesity and trends in obesity rates, then looks at what we can do about it. He takes a look at various popular diets along with surgical and medicine options and concludes that the goal is to be as fit as possible at your current weight and prevent further weight gain, then begin weight loss.

Ananya Roy Discusses Poverty

8232A billion people live under conditions of extreme poverty.

UC Berkeley Professor Ananya Roy calls them the “bottom billion,” but she sees hope. As more people become aware about the nature of poverty, the bottom billion are starting to benefit from poverty alleviation efforts and market forces reaching them. While inequality is at an historic high, Roy sees a new common sense growing around these issues which is reason for optimism.

According to Roy, it is important to develop a more relational view of poverty – that inequity is an issue for all of us, regardless of our economic standing. “I’d like us to move further from asking, how can we help the poor? to asking how’s poverty produced? and how are wealth, power, and privilege produced? When we get to that last set of questions, we’re adopting… a relational understanding of poverty. It’s about our dependencies on the labor of the poor… and how we think about ourselves and our place in the world.”

Mark Juergensmeyer, Director of the Orfalea Center at UCSB talks with Ananya Roy about her path from her upbringing in Calcutta, India to her current position as Professor of City and Regional Planning at UC Berkeley. She is an expert in global poverty, particularly in urban centers, and shares her experiences with the undergraduate program in Global Poverty and Practice which she founded at Berkeley. As a teacher, she uses social and digital media in the classroom to engage and motivate her students. (You can watch Roy’s animated videos on poverty on GlobalPOV.)
