Eagleman argues that expanding our perceptions can foster greater understanding and reduce conflict in society, especially in an era where technology can amplify divisions.

It's Not Just Calories Counting in Weight Loss

While the traditional "calories in, calories out" model holds truth, recent research highlights the role of gut microbes and food "leftovers" in metabolic health. Bioactive compounds, like fibers and polyphenols, regulate metabolism and appetite by interacting with gut microbes, turning unused calories into beneficial metabolites. Still encased in their natural fibers, whole foods lead to more calories being excreted and less absorbed. Mitochondrial efficiency also influences weight gain, and healthy microbiomes optimize calorie burning. Processed foods lack these bioactives, further complicating the weight loss equation. Is weight loss as simple as calories in, calories out? In the end, it's your gut microbes and leftovers that make your calories count.

Tripping With Dogs

A groundbreaking study reveals that humans and dogs can synchronize their brain activity, known as inter-brain activity coupling.
