But our memories are also highly suggestible, and we often misremember events or fabricate memories entirely. In this episode, host Samantha Laine Perfas talks with science researcher Dan Schacter, Alzheimer’s expert Margaret O’Connor, and neuroscientist Venki Murthy about the science of memory – and how we can remember better.

Many diets claim to be good for you. But the Mediterranean diet rises to the top with its research-proven benefits: it’s been shown to increase life expectancy; decrease risk for dementia; improve mental health and cognitive function; and lower the risk of heart disease for nearly every demographic.

In this episode, host Samantha Laine Perfas discuss the Mediterranean diet with nutritional psychiatrist Uma Naidoo and Mediterranean diet expert Miguel Ángel Martínez-González about how people can make nutritional changes that work for them day to day.

In this episode, host Samantha Laine Perfas talks with sleep scientist Rebecca Robbins, psychiatrist Tony Cunningham, and epidemiologist Matthew Weaver about why we should – and how to – get better sleep.

It could be related to lifestyle choices, environmental factors, or an individual’s genetics. In this episode, host Samantha Laine Perfas speaks with global cancer trend expert Tim Rebbeck, oncologist Kimmie Ng, and epidemiologist Tomotaka Ugai about how people under 50 can best mitigate their cancer risk.

Literacy rates in the U.S. have been in decline for a while now. Experts are combing the data for answers. Researchers are examining the role of curricula, teacher training, and classroom best practices to figure out: How do we help our kids read better?

It’s a new era in the fight against cancer. The disease still kills nearly 10 million people worldwide every year, but advances in genomic sequencing and artificial intelligence have ushered in a new era of research. Treatments can now be personalized to patients and someday we might even have vaccines that can prevent the disease altogether. In this episode, host Samantha Laine Perfas, cancer researcher Levi Garraway, radiologist Connie Lehman, and cell therapy expert Cathy Wu talk about how close we are to turning a corner on cancer.

Our planet is filled with plastic. On average, we produce 430 million tons every year, most of which is used only for a short period of time and then discarded. But plastic isn’t just in the environment: it’s now in our bodies. Microplastics have been found in our bloodstreams, lungs, and other organs, and we’re only recently beginning to understand how this affects our health. In this episode, host Samantha Laine Perfas, cell biologist Don Ingber, environmental health scientist Mary Johnson, and nanomaterial researcher Philip Demokritou discuss our destructive relationship with plastic.
