Brains Store Temporary Records Before Creating Life-long Memories

(Credit: Alena Hovorkova/shutterstock) A version of this article originally appeared on The Conversation. The first dance at my wedding lasted exactly four minutes and 52 seconds, but I’ll probably remember it for decades. Neuroscientists still don’t entirely understand this: How was my brain able to translate this less-than-five-minute experience into a lifelong memory? Part of the puzzle is that there’s a gap between experience and memory: our experiences are fleeting, but ...read more

A Brief Guide to Neuro-Products

Posted on Categories Discover MagazineLeave a comment on A Brief Guide to Neuro-Products

On this blog I usually focus on academic, scientific neuroscience. However, there is a big world outside the laboratory and, in the real world, the concepts of neuroscience are being used (and abused) in ways that would make any honest neuroscientist blush. In this post I’m going to focus on three recent examples of neuro-products: commercial products that are promoted as having some kind of neuroscience-based benefit. 1) Neuro Connect Golf Bands We’ll start out with a silly one. Th ...read more

Someday, adolescents sucking tobacco-free Mods and Juuls could face similar regret. Initially hailed as a smoking cessation breakthrough, e-cigarettes have now been raising red-flags for years. Thanks to nicotine, vaping can be just as addictive as true cigarettes.

The Evolutionary Quirk That Made Vitamin B12 Part of Our Diet

Posted on Categories Discover MagazineLeave a comment on The Evolutionary Quirk That Made Vitamin B12 Part of Our Diet

(Credit: bitt24/Shutterstock) Vitamins and other nutrients that we cannot make for ourselves are called essential. It’s a misleading term because “essential” most often means “important,” but in the world of dietetics, it denotes that we must obtain it in our diets. For example, vitamin Q, also called ubiquinone, is extremely important – it’s crucial for cellular respiration in the mitochondria – but it is not deemed essential because our cells s ...read more

The Dukovany Nuclear Power Station in the Czech Republic. (Credit: zhangyang13576997233/Shutterstock) There are 99 nuclear reactors currently operating in the United States. The power they generate is free of carbon dioxide emissions, but as a byproduct, they also generate small amounts of nuclear waste in the form of depleted uranium. Even after the uranium in the fuel reactors is spent, or depleted, it remains radioactive, and that means storing it is difficult. Controversy over a permanent ...read more

Growing AwarenessAlthough not exactly invented at Burning Man, the practice of contemporary archaeology is fairly new, and still far from mainstream. Arguably the earliest example, and still one of the most famous, originated in 1973 when a University of Arizona archaeologist named William Rathje decided to study garbage in Tucson. As a specialist in Maya civilization, Rathje was well practiced in the study of middens, heaps of ancient rubbish that had provided his field with most of its knowled ...read more
