DoD STEM’s Post

With winter break coming up or already in progress, I think is a good idea for me to share a science activity that you can do at home with your scientist(s). Check out this video and others on my YouTube Channel: https://lnkd.in/eMMGZyV5

Happy Holidays! This holiday season, have you received any large tubs of flavored popcorn? Or maybe microwaved some popcorn for a holiday movie? If you've ever wondered how popcorn actually works (like I did!), check out the newest post on my blog, 'a Morsel of Science'! Happy snacking!

𝗣𝗲𝗼𝗽𝗹𝗲 𝗕𝗲𝗵𝗶𝗻𝗱 𝗦𝗰𝗶𝗲𝗻𝗰𝗲 🔬 𝐌𝐞𝐞𝐭 Florian Bahut, 𝐑&𝐃 𝐏𝐫𝐨𝐣𝐞𝐜𝐭 𝐋𝐞𝐚𝐝𝐞𝐫 𝐚𝐭 𝐋𝐚𝐥𝐥𝐞𝐦𝐚𝐧𝐝 𝐎𝐞𝐧𝐨𝐥𝐨𝐠𝐲, featured in our new "People Behind Science" series! 🌟 🍷 In his everyday work, Florian explores the complexities of wine oxidation. 🧬 Dive deeper as Florian discusses the power of metabolomics in understanding wine's chemical signature and predicting its aging potential. In his video, he notably explains how specific inactivated yeasts with guaranteed glutathione level confer to the wine an efficient protection against browning and aroma oxidation, a better aromatic expression, freshness, and a longer preservation of thiols and esters. 👇 Watch the full interview to see how Florian's research is shaping modern winemaking practices. https://ow.ly/7pcI50SEoJ0 And thank you Florian for sharing your knowledge with us! hashtag #LallemandOenology #WineScience #Innovation #OxidationManagement #Metabolomics #Winemaking

Watch an electronic tongue tasting wine, dudes! Even though machines may outperform humans in certain aspects --employing biosensors and statistical methods to analyze data-- humans remain a vital part of the sensory evaluation process no matter the food or beverage being tested since they additionally apply their cognitive abilities and sensory apparatus along the whole process. Charles Diako, a PhD candidate at Washington State University, notes that "the e-tongue provides an objective measurement of taste profiles, which we aim to correlate with human sensory evaluations." Unlike humans, who detect flavors, the robotic tongue distinguishes taste compounds at the molecular level. As highlighted by WSU's research team, "human evaluation is more sensitive and incorporates a vast array of information and perception in response. This technology will not replace human evaluation." They also emphasize something we all involved with sensory analysis should never, ever, lose sight of: ▫️"The complexity of our perception cannot be replicated by an instrument." I would say "any" instead of "an" instrument, but it's the instrumental analysis that is being called into question by the video and that’s totally cool! 🚩Watch the beast here: https://lnkd.in/dvNJX9zG Dope, isn't it? #Etongue #SensoryEvaluation #WineTasting #WineChemistry

A question for readers, fellow journalists, cocktail imbibers: what do you think of "changing" an interview question after the fact? Interviewing Trevor Kallies, director of bar and beverage for Science of Cocktails at Science World, last week one of my questions was "Were there any cocktails that have just kind of crashed and burned? Set the place on fire or anything like that?" Not a bad question, to be sure. But when transcribing and editing the interview for print/online I changed it to: "Have there been any cocktails that have crashed and burned? Set the place on fire or opened up a rip in the multiverse?"—making the interviewer (me) look a little more imaginative than he actually was, at least at that time of the morning. So what do you think? Bad journalistic practice? Or within acceptable bounds of sprucing up the piece for reader consumption? Science of Cocktails takes place tonight, April 11, at Science World. You can read more about the annual event at the link below. Note: the story includes a recipe for a peanut butter old fashioned! #scienceofcocktails #Vancouver #journalism #cocktails #fundraisers #science #recipes

Reflection: This paper indirectly raises a general philosophical issue regarding relationships between embodied biological matter, #experience and the statistical regularities that bind such notionally disparate artefacts, entities and systems. Is mathematical structure additional to, as in some manner being more or less isomorphic with but separate from, experience? Where, then, would we expect to find an archive or (algorithmic, #compression) library of all this mathematical structure, of the apparently underlying rules and downstream statistical regularities that inflate them with perceived telos or cultural and psychological significance? System #memory is distributed in 𝘢𝘯𝘥 𝘢𝘴 the system by some kind of as yet indeterminately emergent biological inevitability? Great, but that still leaves an epistemological hole large enough to hide the USS Eldridge in. These systems in some sense logically and referentially "contain themselves". (Non-orientable surfaces are in play.) Experience is not outside the system and nor is the #logic, nor is whichever iteration of physical theory percolates through language and culture into paradigmatic (if pragmatic) ascendance. Nor is mathematical #abstraction an externality. There are no Archimedes points of objective clarity here. The entangled systems of matter and information are in some sense identical. Is experience sensibly articulated as separate from or identical with the complex #statistical substrate that sustains it? If not, how is it that these at least superficially appear as separate artefacts, entities, systems? If the structure of the world (and of self, of the languages and abstraction with which such concepts are rendered intelligible) mirrors scientific theory that explains them, and if the structure of scientific #theory perhaps inevitably reflects the structure of the world, where is the logical, mathematical #complexity and instruction set for statistical correspondence actually stored or recorded? ----- Cybernetic reflections, an occasional series...

Delighted to present my latest LinkedIn post delving into the intricate history and evolution of coffee. Through meticulous research and analysis, I uncover the captivating journey of this beloved beverage from its origins to its current global prominence. Join me in exploring the profound cultural and economic impact of coffee on our world. #coffeeHistory #coffeeevolution #professionalInsights #mediumblog #contentwriting #digitalmarketing #followformore #connectwithme

https://lnkd.in/dVasyijy Attention coffee enthusiasts! Ever wondered about the glossy sheen on your coffee beans? Our latest blog post explores the intriguing phenomenon of shiny coffee beans. Delve into the science of coffee and uncover the reasons behind their sparkle.

In case you like tea and science as well, here’s a note, why both of them are compatible.

Applied research has always been a focus for Thoughtful Viticulture. Providing tangible data on approachable techniques to improve viticulture and wine quality that support sustainability is why our slogan is "sustainable science-based solutions".   It’s been a whirlwind past month or so, as we’ve been gathering our thoughts together, doing background research, designing experiments, and scoping out potential collaborators and vineyards for some research projects we’d like to undertake on behalf of the NZ wine industry. We’ve put in EOIs for multiple research projects aimed at helping growers with “alternative” management strategies that improve quality and sustainability, while also managing input costs.     The next few blog posts will explore some of the topics that have inspired our projects. As a recovering academic, I’m no longer driven by being the first to publish, so can be a little more open about research ideas in the hopes of inspiring others and gathering cooperators. I want us all to do better growing grapes, regardless of where we are. #thoughtfulviticulture #undervinecovercrops #herbicidereduction #herbicideelimination #dontundermineyourundervine https://lnkd.in/gs5mMUYx
