Millie Dresselhaus on Energy Sustainability

766 UCTV’s Women in Science kicks off the month of April by celebrating an influential woman in the scientific field, MIT Professor Mildred Dresselhaus.

A pioneer in Nanoscience, Dresselhaus is one of the first scientists to open the door to using carbon based materials on a nanoscale. Some of her notable contributions paved the way for modern day carbon nanotubes and nanoscale thermoelectricity.

Dresselhaus’ current career has focused on advancing science and engineering in its more basic aspects, as well as advancing energy sustainability. In a recent talk at UC Santa Barbara, Dresselhaus discusses the world energy outlook and sustainability, nanostructures and recent advances in thermoelectrics.

“The take-home message here, is that it’s not a bad idea to try to make the world a better place, when called upon to do so,” Dresselhaus mused.

Mexico: Twenty Years After NAFTA

27717This year marks the 20th anniversary of the North American Free Trade Agreement, an important milestone for the U.S., Mexican, and Canadian regional economic partnership.

Before NAFTA was launched 20 years ago, critics worried that the United States would lose jobs and more to the south, to Mexico. That did not happen. In fact, employment rose, commercial ties with Canada and Mexico nearly tripled, and the national economies became more integrated in some industries.

Despite these and other benefits, concerns remain and the pact continues to be controversial. As part of its ongoing Master Class series, “Mexico: Twenty Years After NAFTA,” the Osher Lifelong Learning Institute presents Mexico — Drugs and Violence — Can Recent Progress be Sustained? with David Mares.

Tune in to hear David Mares, director of the Center for Iberian and Latin American Studies at UC San Diego, discuss NAFTA’s effect on drugs and violence in Mexico and how recent progress is fundamental to Mexico’s future and of great interest to the United States.

This series is presented by The Osher Lifelong Learning Institute and the Center for U.S.-Mexican Studies at UC San Diego.

Turning Cancer into a Chronic, but Controllable, Disease

768Dr. Patrick Soon-Shiong, founder of NantWorks, describes his vision for turning cancer into a chronic but controllable disease by using advanced rapid gene sequencing, supercomputing and other methods of analysis to transcend the genome to the proteome.

This approach has the potential to redefine how cancer is diagnosed and to develop therapies precisely tailored to the molecular profile of a particular tumor. Dr. Soon-Shiong anticipates a revolution in drug research, development and delivery of molecularly designed cancer treatments to patients.

Nutrition Labels: How Sweet It Is

23717Lately, the subject of added sugar in our diets has been in the news. Most recently the FDA announced the first makeover of the nutrition label since it appeared twenty years ago. One of the big changes is the requirement to note how much added sugar is in a product. The new labeling now indicates a food’s naturally occurring sugar as well as its added sugar content.

Changes like these have been reverberating around the globe. Before the FDA’s changes in labeling, countries like France and Mexico increased taxes on sugary drinks specifically to treat the epidemic of added sugar’s health effects in their countries, and The United Nations identified the cost of treating the chronic health effects of added sugar as a grave threat to world economies.

23901One reason for these seismic changes in global health policy is UC San Francisco endocrinologist Dr. Robert Lustig, a leader in the movement to recognize that sugary foods are at the root of the obesity epidemic and the increase in metabolic disease. As a principal in UC San Francisco’s Center for Obesity Assessment and Treatment, Dr. Lustig is a rigorous scientist digging for the reality about foods’ effects on our health.

While a tireless researcher and clinician, his contributions to this movement in the public sphere are many. One of the most seminal of these was one of UCTV’s most popular programs, Sugar: The Bitter Truth, which details exactly how added sugar corrupts human metabolism. This stark expose of the consequences of added sugar has been viewed over 4 million times on YouTube.

The program resonated throughout media, from The New York Times, to UK’s Channel 4′s Dispatches, to CBS’ Sixty Minutes to CNN’s Sanjay Gupta, bringing out the hard facts about added sugar to an often-disbelieving world.

637That one lecture was so popular that UCTV’s YouTube Original Channel UCTV Prime followed with the multi part series The Skinny on Obesity. Featuring Lustig and his colleagues at UC San Francisco detailing the insidious effects of added sugar on human health, the series has been viewed over 1.6 million times on YouTube.

And so Dr. Lustig and UCTV continue. Last October, Dr. Lustig shared the latest information about added sugars with the UCTV program Fat Chance: Fructose 2.0 and released The Fat Chance Cookbook, a companion to his New York Times Best Seller Fat Chance.

And now, for the first time, the CDC has reported a decline in childhood obesity in 2 to 5 year olds.

Better research, better information, and practical steps to improving the health of people around the globe — hopefully the bitter truth will lead to a sweeter future.

PrEParing for HIV: An Epidemic Interventions Initiative

Researchers at the University of California are getting closer to preventing HIV/AIDS.

PrEP, or pre-exposure prophylaxis, is a prevention strategy that reduces the risk of getting infected with HIV by up to 99 percent. This four-year, multi-pronged series of demonstration projects targets young men who have sex with men in Los Angeles, Oakland and San Diego where participants agree to take a Truvada pill daily.

Producer Shannon Bradley was excited about the opportunity to tell the story of PrEP, both from the perspective of researchers and from those who are taking the medication. “We really appreciated how willing the doctors and the participants were to be open with us,” she said, “especially the participants. Each of these young, HIV negative men seemed to take pride in their role in these PrEP studies.”

Truvada_WrenchUC doctors and participants on PrEP explain how a daily dose of the pill Truvada can curb the spread of HIV by preventing it from replicating when it comes into contact with a host. According to Raphael Landovitz, MD, viruses like HIV can’t be killed. “I think of them as robots, and the way Truvada works is, it’s a monkey wrench that gets thrown into the gears of the robot that is HIV.”

The key, however, is consistency. To work effectively, the pill must be taken every day prior to exposure. Methods to increase adherence among the participants are also being tested, including daily reminders via text messages and tracking usage of the medication with special “Mems caps” for the pill bottles.
