Contemporary Science Issues and Innovations 09/20/22

Why Are We Spending Billions on Carbon Capture & Storage? Despite the hype, carbon capture and storage (CCS) is not a solution to the CO2 problem that has caused climate warming. Taxpayers have paid billions of dollars for research and experimental projects that subsidize the fossil-fuel industry but those projects failed to reduce CO2. Dr. Harvey discusses how these ineffective CCS projects continue to be promoted and explains the necessity of shifting to renewable energy. Charles Harvey, Ph.D., Professor of Civil and Environmental Engineering, MIT.

Dr. Nocera describes the numerous updates of the bionic leaf, the particular challenge of hydrogen, and the present status of this promising innovation. 

Contemporary Science Issues and Innovations - The Struggle to Ban Pesticides That Disrupt Brain Development 07/05/22

For almost 30 years, Dr. Philip Landrigan and other distinguished scientists appealed to the EPA to ban chlorpyrifos and widely used pesticides known to impair brain development. The link between chlorpyrifos and brain disorders such as autism and ADHD was well known for years, but the manufacturers of this toxin were able to block efforts to ban chlorpyrifos. Dr. Landrigan explains the effects of this toxin, and also scientists’ decades-long effort to protect pregnant women, children, and farm workers and communities. This struggle has raised the question: Who does the Environmental Protection Agency protect: industry or the public? 

Contemporary Science Issues & Innovations 06/07/22

Who Funds the FDA And Why Does It Matter? The Food and Drug Agency (FDA) was established in 1938 to ensure the quality of foods and medications. At the time, many medications and processed foods contained impurities and toxins that were threatening public health. When the FDA took charge of testing and guaranteeing the safety of products it represented the public interest and was funded by the taxpayer, not the pharmaceutical and food companies. That situation began to change in the 1980s when a special arrangement was initiated in which pharmaceutical companies paid fees to the FDA that were meant to expedite the testing and approval of new medications. The public is largely unaware of this partnership between the regulator (FDA) and the regulated (pharma industries). Dr. Kesselheim explains the background and the concerns about this arrangement. Aaron S. Kesselheim, M.D., J.D., M.P.H., is a Professor of Medicine at Harvard Medical School and a faculty member in the Division of Pharmacoepidemiology and Pharmacoeconomics in the Department of Medicine at Brigham and Women’s Hospital.

Dr Bolender discusses the known settlements and also the question of Viking settlements in North America. : Douglas Bolender, Ph.D., Research Assistant Professor at the Andrew Fiske Memorial Center for Archaeological Research and the Department of Anthropology, University of Massachusetts, Boston. 

Contemporary Science Issues and Innovations 05/18/22

"Hard Facts About Carbon Capture and Storage" How much CO2 does the much-promoted carbon capture and storage (CCS) technology actually extract from the atmosphere—and at what cost? Answer: very little extraction and at great cost with serious environmental risks. CCS keeps the fossil fuel industry going at taxpayer expense, although renewable energy and biological sequestration are available, much less expensive, and environmentally beneficial --definitely the only viable solution to the excess atmospheric CO2 crisis. This discussion provides important facts the public rarely gets. Featuring June Sekera, MPA, Senior Research Fellow, Visiting Scholar, The New School and Neva Goodwin, Ph.D., Co-Director, Global Development and Environment Institute, Tufts University.

They Didn't Believe It! - Dark Matter - 12/02/2019

Our “normal” matter is stuff made of atoms –like stars, planets, creatures –everything in nature. But that’s only a very small amount of the actual matter in the universe. Most matter is invisible “dark matter,” and scientists do not know what it is. The idea of some type of “different” matter emerged in the 1800s –and was ignored-- the early 1900s—ignored again- and finally was confirmed in the 1970s.

In this presentation, Dr. Reinhart outlines such a model based on a neighborhood proposal in Boston.

They Didn't Believe It! The Atom - 11/06/2019

The concept of THE ATOM originated in ancient India and Greece in roughly 500 BCE. The concept was dismissed by many leading thinkers through the ages. Finally, the atom concept began to gain acceptance in the Europe in the 1600s, more so in the 1800s, and finally gained full respect in the late 1900s. The concept also evolved over those centuries. Today, of course, no one doubts the existence of the atom.

Dr. Myers discusses the engineering and logistical aspects of developing wind farms and the exciting future for this area of renewable energy.

Contemporary Science Issues and Innovations: Psychiatric Drugs: Why They Often Fail Us Over Long Term 4/23/19

Psychiatric Drugs: Why They Often Fail Us Over Long Term. More than one in five Americans now takes a psychiatric medication. Yet, as our use of these medications has soared, so too has the burden of mental disorders in our society. Why would this be so? Unfortunately, research has shown that long-term outcomes for medicated patients are poor.

How does the brain acquire and process language? How about multiple languages? And how about a whole lot of languages? Dr. Fedorenko describes what cognitive science knows and what is still to be learned. She and her associates focus on how the brains of multilingual people (polyglots) process very different types of languages. They also investigate those rare individuals who learn dozens of languages (hyperpolyglots).

Contemporary Science Issues and Innovations: When Industry Hides the Facts about Toxins

Dr. Philippe Grandjean, a prominent endocrinologist discusses the health and environmental impact of perfluorinated compounds (PFAS, PFOS), chemical compounds used in many products -from popcorn bags to fire-fighting foam to upholstery materials. These compounds are now found globally -- in people, animals, and environment. They affect, among other things, the brain, kidneys and the immune system, and are associated with a number of diseases. The producers of PFOAs were aware of the toxicity of these chemicals even in the late 1970s, but only recently have scientists been able to obtain that data. Because PFAS remain in the body over the lifespan, the withholding of data for decades has undermined medical research.

Dr. Alan Jasanoff discusses his book, "The Biological Mind: How Brain, Body, and Environment Collaborate to Make Us Who We Are". In his new book and in this discussion, Dr. Jasanoff explains why the brain must be considered within its biological, natural and social environment. The tendency to see the mind as completely autonomous, a view he calls the “cerebral mystique” doesn't hold up. Jasanoff’s discussion includes brain dysfunctions as well as recent trends such as brain hacking –and the transhumanist aspiration that our brains can someday be preserved and then revived much later.
