Lambert’s findings suggest that embracing joy and anticipation can transform behavior and mental health in rats and humans, underscoring the value of enjoying life’s journey, not just the destination. I’m a neuroscientist who taught rats to drive − their joy suggests how anticipating fun can enrich human life.

The Brain Isn’t the Only Keeper of Memories

Traditionally, memories are believed to reside solely in the brain, but a new study reveals that non-neural cells in the body also hold a memory function. Scientists at NYU found that cells outside the brain can “learn” and activate a memory gene in response to specific patterns of chemical signals, similar to how brain cells respond during spaced learning. This discovery suggests memory might be a cellular feature beyond the brain, potentially impacting future treatments for memory-related conditions and enhancing learning by targeting body-wide cellular responses. Memories are not only in the brain, human cell study finds (thanks, Amy!).

Forbidden Fruit Loophole: Why Some Banned Foods Make It to U.S. Plates

The U.S. food approval system allows certain additives banned in other countries to remain on American grocery shelves. Unlike Europe, which adopts a precautionary stance, the U.S. regulatory process is constrained by funding, industry influence, and a significant loophole: the “Generally Recognized as Safe” (GRAS) exemption. This GRAS policy lets companies self-determine safety without FDA review, leading to chemicals like titanium dioxide in foods despite potential risks. While some states are moving to ban specific additives, federal change remains slow, hindered by resource limitations and competing priorities within the FDA.Why US foods, including Halloween candy, have additives and chemicals banned in other countries | Vox.
