On May 5, 1961, Alan Shepard became the first American in space when he piloted the Mercury capsule Freedom 7. His sub-orbital journey lasted 15 minutes. Like most children who grew up in the early era of space flight, I remember this moment well.
The flight was extra special for me because my dad, Arthur L. Levine, worked for NASA. As a human resources administrator, he recruited John Glenn, who in 1962 became ...read more
Scientists find that parasites dramatically alter how much methane a sheep emits.
It’s estimated that 40% of greenhouse gas emissions come from agriculture, and a substantial portion of that is directly ’emitted’ by livestock. And just last year, climate scientists reported that we’ve actually been underestimating the extent to which the combined belches and flatulence of farmed animals contributes to climate change by 11%. Unsurprisingly, there& ...read more

[Note from the authors of “Seriously, Science?”: After nine years with Discover, we’ve been informed that this will be our last month blogging on this platform. Despite being (usually) objective scientists, we have a sentimental streak, and we have spent the last few days reminiscing about the crazy, and often funny, science we have highlighted. Therefore, we have assembled a month-long feast of our favorite science papers. En ...read more

I’m always on the look out for interesting images of Earth shot from space so that I can share them here at ImaGeo. And when I saw the one above, I just couldn’t resist it.

Often, the cloud deck extends along the coast of California and down into Baja in a more or less continuous manner, as you can see in the image at righ ...read more

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
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

How many breathless older smokers rue the day they first inhaled nicotine and tar?
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. And even if youthful vapers never drag on a Camel, preliminary evidence suggests they may still get chronic bronchi ...read more

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
