Hey Bill Nye! What if I’m not a science person?
High school junior Caitlin is worried. She wants to be a scientist but is struggling with it a little bit in school—is there hope for her career?
Bill Nye, The Science Guy
Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life. In Seattle Nye began to combine his love of science with his flair for comedy, when he won the Steve Martin look-alike contest and developed dual careers as an engineer by day and a stand-up comic by night. Nye then quit his day engineering day job and made the transition to a night job as a comedy writer and performer on Seattle's home-grown ensemble comedy show “Almost Live." This is where “Bill Nye the Science Guy®" was born. The show appeared before Saturday Night Live and later on Comedy Central, originating at KING-TV, Seattle's NBC affiliate. While working on the Science Guy show, Nye won seven national Emmy Awards for writing, performing, and producing. The show won 18 Emmys in five years. In between creating the shows, he wrote five children's books about science, including his latest title, “Bill Nye's Great Big Book of Tiny Germs." Nye is the host of three currently-running television series. “The 100 Greatest Discoveries" airs on the Science Channel. “The Eyes of Nye" airs on PBS stations across the country. Bill's latest project is hosting a show on Planet Green called “Stuff Happens." It's about environmentally responsible choices that consumers can make as they go about their day and their shopping. Also, you'll see Nye in his good-natured rivalry with his neighbor Ed Begley. They compete to see who can save the most energy and produce the smallest carbon footprint. Nye has 4,000 watts of solar power and a solar-boosted hot water system. There's also the low water use garden and underground watering system. It's fun for him; he's an engineer with an energy conservation hobby. Nye is currently the Executive Director of The Planetary Society, the world's largest space interest organization.
Caitlin: Hey Bill. I’m currently a junior in high school and I’m getting ready to apply to college in the near future. I’ve always loved science but it’s never been a subject to come naturally to me and I’ve always struggled in it a little bit. Do you think that there’s a possibility I could pick science as my major and become hopefully a scientist one day in the future despite the fact that it doesn’t come naturally to me? Thank you very much.
Bill Nye: Caitlin, of course there’s a chance for you to become a scientist. What, are you kidding me? Of course, young woman, go for it! There’s all sorts of sciences that I bet will come naturally to you. Chemistry and physics may not be your thing, or maybe they’re your favorite. Statistics always made me crazy although I did it. So yes, there’s a science for you, you’re doggone right.
I would please consider pursuing as many science courses as you can handle. You don’t have to start with 400-level courses, you know, senior in college level courses, just try astronomy. Astronomy is empowering and wonderful. It’s humbling and empowering all at the same time. Try biology. The discoveries being made in genetics right now are amazing and will change the course of human history. Try chemistry. Without chemistry we would not have these textiles and this fabulous glass in these electronics that are enabling us to have this computer conversation. No, just go for it, of course!
The big thing I remind everybody though is algebra. Algebra is really important and it was hard for me too. You’ve just got to practice. You’ve got to practice algebra over and over. And the reason it’s valuable, apparently, research suggests thinking abstractly about numbers enables you to think abstractly about all sorts of things.
So go back if you need to. If you’re a junior just do a little more algebra and I bet you’re more comfortable with the whole idea. And you might change the world. Go get 'em, Caitlin!
What do you do if you're a diehard science lover who dreams of one day donning a lab coat professionally, but you're struggling with the work at school? That is Caitlin's predicament—but that's not how Bill Nye sees it. Your school classes may not come naturally to you, but that's because science is a skill, not a talent. No one is born a scientist, it is something you become over time with hard work, and if perhaps biology isn't hitting home with you, you may find your groove in astronomy. Physics isn't for everyone, but chemistry might be your match. The point is, there is a kind of science for everyone. So to change the world as a scientist, here's what you have to do: #1. Don't give up before it's begun. #2. Study hard and get to college. #3. Practice science as a way of thinking (and algebra specifically) to develop abstract thinking skills. #4. Find the field in which you belong, and start to chip away at change. Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.

Surprising Science
The COVID-19 pandemic has introduced a number of new behaviours into daily routines, like physical distancing, mask-wearing and hand sanitizing. Meanwhile, many old behaviours such as attending events, eating out and seeing friends have been put on hold.
<p>However, one old behaviour that has persisted, and <a href="https://dx.doi.org/10.1016%2Fj.pcad.2020.04.005" target="_blank">has arguably been amplified due to COVID-19, is sitting</a> — and it is not surprising to see why. Whether sitting during transportation, work, screen time or even meals, everyday environments and activities are tailored nearly exclusively to prolonged sitting. As such, sedentary behaviours, like sitting, make up the vast majority of our waking day. </p><p>Pre-COVID-19 estimates place the <a href="https://doi.org/10.1186/s12966-020-00925-8" target="_blank">average Canadian adult's sedentary behaviour at around 9.5 hours per day</a>. Current daily sedentary time is likely even higher as a result of stay-at-home orders, limitations on businesses and recreational facilities, and <a href="https://www150.statcan.gc.ca/n1/daily-quotidien/200527/dq200527b-eng.htm" target="_blank">elevated health anxieties</a>. </p><h2>Health vs. well-being</h2><p>This is a problem, given that chronic excessive levels of sedentary time have been linked to <a href="https://doi.org/10.1371/journal.pone.0105620" target="_blank">greater risk of diabetes, heart disease, mortality and even some cancers</a>. However, for many people, their own judgments and feelings about their quality of life (also known as <a href="https://dictionary.apa.org/subjective-well-being" target="_blank">subjective well-being</a>) may be more important and relevant for informing their health decisions and behaviours than potentially developing chronic diseases.</p><p>Subjective well-being encompasses <a href="https://nobaproject.com/modules/happiness-the-science-of-subjective-well-being" target="_blank">an individual's own evaluation of their quality of life</a>. It includes concepts like <a href="https://dictionary.apa.org/affect" target="_blank">affect</a> (positive and negative feelings) and <a href="https://dictionary.apa.org/life-satisfaction" target="_blank">life satisfaction</a>. Interestingly, these evaluations can conflict with physical health outcomes. For example, a person could have diabetes but still report good subjective well-being, while someone with no physical health conditions may report poor subjective well-being. </p><p>This is important, as it means how an individual feels about their own health may not always align with what their body may demonstrate. That's why evaluating subjective well-being is vital for painting a holistic picture of health. </p><h2>Different contexts of sitting</h2><p>Relatively little research has examined the relationships between sedentary behaviour and subjective well-being. Exploring these relationships is important, as different contexts of sitting — such as socializing versus screen time — may yield different feelings or judgments of subjective well-being, unlike relationships between physical health and sedentary behaviour, which <a href="https://doi.org/10.1146/annurev-publhealth-040119-094201" target="_blank">tend to be more consistent</a>. </p><p>As health psychologists focused on physical activity and sedentary behaviour, we <a href="https://doi.org/10.1016/j.psychsport.2021.101920" target="_blank">reviewed the scientific literature</a> describing relationships between measures of sedentary behaviours such as physical inactivity and screen time, and subjective well-being as reflected by affect, life satisfaction and overall subjective well-being. </p><p><a href="https://www.sedentarybehaviour.org/2021/03/04/relationships-between-indices-of-sedentary-behavior-and-hedonic-well-being-a-scoping-review/" target="_blank">Our review</a> highlights three main findings. First, sedentary behaviour, physical inactivity and screen time demonstrated weak but statistically significant correlations with subjective well-being. In other words, those who reported sitting more often and spending longer periods with no physical activity reported lower positive affect, higher negative affect and lower life satisfaction than those who sat less and moved more. </p><p>We also found that this relationship was most apparent in studies that compared people who were very sedentary to those who had more active lifestyles. </p><h2>Not all sitting is bad sitting</h2><p>Our second main finding relates to the context of the sedentary behaviour. While many studies examined overall sedentary behaviour and physical inactivity, some studies looked at specific contexts or domains of sitting and its relationship with subjective well-being. These studies revealed that different domains of sedentary behaviour have unique relationships with subjective well-being. </p><p>For example, screen time was consistently and negatively associated with subjective well-being. However, domains like socializing, playing an instrument and reading actually demonstrated positive associations with subjective well-being. These results differ from the traditional health-related sedentary behaviour research, in which <a href="https://doi.org/10.1146/annurev-publhealth-040119-094201" target="_blank">all sedentary behaviour is viewed as harmful to health</a>. </p><p>Our review suggests that some types of sedentary behaviour may be beneficial to quality of life. Rather, not all sitting is the same in terms of subjective well-being. So when people work towards reducing their sitting time, they should consider not just how much to reduce, but what kind to reduce.</p><h2>Less sitting is good for everyone</h2><p>Our third main finding concerns overall sitting and self-perceived levels of sedentary behaviour. Most studies found a weak statistically significant association between higher overall sedentary time and lower subjective well-being. However, in studies where participants were asked to compare their sedentary behaviour to how much they normally sit, those who perceived themselves as more sedentary than usual reported significantly poorer subjective well-being.</p><p>These findings suggest that how much an individual sits overall may not be as important as how much an individual sits compared to their usual level of sitting. This infers that anyone, regardless of how much they normally sit or <a href="https://doi.org/10.1016/S0140-6736(16)30370-1" target="_blank">are physically active</a>, may potentially benefit from sitting less.</p><p>COVID-19 continues to influence daily life and routines. Even as businesses and gyms eventually reopen, and we feel more comfortable gathering with others and eventually stop wearing masks, we will almost certainly continue to sit and sitting will continue to change how we feel. While we may not be able to eliminate all of our sitting, we can all be mindful of both how much we can reduce it and where we can reduce it from to be healthier <em>and</em> feel better.<img alt="The Conversation" height="1" src="https://counter.theconversation.com/content/156289/count.gif?distributor=republish-lightbox-basic" width="1"></p><p><a href="https://theconversation.com/profiles/wuyou-sui-1024154" target="_blank">Wuyou Sui</a>, Postdoctoral fellow, Behavioural Medicine Lab, School of Exercise Science, Physical & Health Education, <em><a href="https://theconversation.com/institutions/university-of-victoria-1182" target="_blank">University of Victoria</a></em> and <a href="https://theconversation.com/profiles/harry-prapavessis-1115239" target="_blank">Harry Prapavessis</a>, Professor, Kinesiology, <em><a href="https://theconversation.com/institutions/western-university-882" target="_blank">Western University</a></em></p><p>This article is republished from <a href="https://theconversation.com" target="_blank">The Conversation</a> under a Creative Commons license.

VR experiments manipulate how people feel about coffee
A new study looks at how images of coffee's origins affect the perception of its premiumness and quality.
11 April, 2021

Surprising Science
- Images can affect how people perceive the quality of a product.
- In a new study, researchers show using virtual reality that images of farms positively influence the subjects' experience of coffee.
- The results provide insights on the psychology and power of marketing.
<p>Are coffee consumers influenced by the imagery and story around the production of the drink? Such was one of the central questions of a new <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2021.586983/full" target="_blank">study</a> that explored the power of marketing on how "premium" aficionados consider coffee to be. </p><p>The researchers set out to explore whether the origins of the coffee can affect the perception of its quality in the minds of the drinkers. In particular, they focused on the concept of terroir, the special characteristics conferred upon the coffee by the specific terrain in which it was grown. </p><p>"Terroir is more than a mere geographical link between product and land," write the authors. "It relates to the idea that products are a unique expression of different environmental and sociocultural characteristics of a specific place." Thus, focusing a customer's attention on the environment in which the coffee was grown might make the product seem more authentic and of better quality.</p><p>Therefore, the researchers examined the effect of images on the coffee-drinking experience in three experiments. The study was carried out by the food scientist Francisco Barbosa Escobar from Aarhus University in Denmark and marketing experts Olivia Petit from the Kedge Business School in Marseille, France, and Carlos Velasco from the BI Norwegian Business School in Oslo, Norway. Incidentally, Norwegians are among the world's top coffee consumers, with an average Norwegian adult consuming around 4 cups of coffee a day, reports<a href="https://www.ssb.no/utenriksokonomi/artikler-og-publikasjoner/kaffeavhengige-nordmenn" rel="noopener noreferrer" target="_blank"> Statistics Norway</a>.</p><p>The first experiment involved 770 non-expert participants from the UK. They were shown online images and descriptions of four different specialty coffees, traded by a Norwegian coffee company. The researchers found that coffees with pictures of farms were rated higher in premiumness by the subjects than coffees with pictures of cities.</p><p>For the second and third experiments, the study used virtual reality environments of Times Square in New York City and a farm in Kenya as well as a control setting of a white room. The second experiment engaged 143 non-expert participants recruited via a behavioral studies platform at the BI Norwegian Business School in Oslo, Norway. The participants were asked to smell a sample of quality ground coffee from Kenya while at the same time traversing a virtual reality atmosphere. The subjects were then asked to rate the coffee. </p><p><br></p><p class="shortcode-media shortcode-media-rebelmouse-image">

Conversely, subjects rated coffee as sweeter when inside the control VR atmosphere compared to the city VR atmosphere. Furthermore, coffee was considered more premium when subjects were in the farm VR atmosphere compared to the control, but there was no difference in premiumness score between farm and city.</p><p>For the third experiment, the research team involved 34 people who were professionals in the coffee industry. They were asked to taste and score Kenyan coffee while being in the same city and farm VR environments used in the previous experiment. The results revealed a strong effect of atmosphere on how much the experts enjoyed their experience, with a much greater preference for the farm setting versus the control environment of a white room. </p><p>But the different VR atmospheres had little effect on how the experts rated the premiumness of the coffee. The researchers believe that "given their specialized knowledge, coffee professionals examined more objective attributes of the coffee and could discriminate intrinsic factors relevant for the assessment of the coffee from irrelevant extrinsic cues."</p><p>The researchers think their results can lead to developing more immersive marketing experiences in virtual reality, which could be groundbreaking in many industries. A premium experience can lead to customers paying premium prices.</p>

Your body’s full of stuff you no longer need. Here's a list.
Evolution doesn't clean up after itself very well.
17 January, 2019

Surprising Science
- An evolutionary biologist got people swapping ideas about our lingering vestigia.
- Basically, this is the stuff that served some evolutionary purpose at some point, but now is kind of, well, extra.
- Here are the six traits that inaugurated the fun.
Evolutionary anthropologist and Boston College <a data-vivaldi-spatnav-clickable="1" href="http://dorsaamir.com" target="_blank">post-doc</a>, <a data-vivaldi-spatnav-clickable="1" href="https://twitter.com/dorsaamir" target="_blank">Dorsa Amir</a>, started the whole thing with a <a data-vivaldi-spatnav-clickable="1" href="https://twitter.com/DorsaAmir/status/1085227486869377024" target="_blank">series of eight tweets</a>, and boy did she start something fun. Amir laid out a list of weird, once-useful details of the human anatomy that we continue to carry around within — and on — us. Basically, this is the stuff that served some evolutionary purpose at some point, but now is kind of, well, extra.<p><br></p><p>Natural selection, after all, has no reason to clear away unnecessary traits if they pose no evolutionary disadvantage. And when we say "started the whole thing," what we mean is that, this being Twitter, some arguing was inevitable. Some people took issue with Amir's use of the word "vestigial." One issue with the word is that early traits may still be beneficial in ways we don't yet know — the microbiome-managing <a data-vivaldi-spatnav-clickable="1" href="https://www.webmd.com/digestive-disorders/news/20071012/appendix-may-have-purpose#1" target="_blank">appendix</a> and the immune system's <a data-vivaldi-spatnav-clickable="1" href="https://www.livescience.com/62447-tonsils.html" target="_blank">tonsils</a> were both considered among these for some time. A trait's stated assumed value is also always just our best guess, so a certain amount of uncertainty is understood to be baked-in. It's important to remember, too, that if a mutation just happened to happen and persisted because it was useful, it's not the same thing as saying it has a <em>reason</em> to exist. The <em>reason</em> was randomness, unless one doesn't believe in evolution.<br></p>Which gets us to the second type of argument Amir's posts generated. Some creationist-intelligent design believers seem to be patrolling Twitter to shout down references to science where it arises. Probably this post will also get them going. Amir has nonetheless started a list and a conversation that is totally worth checking out, hair-splitting aside. Here are the six traits that inaugurated the fun.
The plica semilunaris

Image source: Henry Gray / Wikimedia commons
<p>At the inner corner of our eyes, closest to the nasal ridge, is that little pink thing, which is probably what most of us call it, called the caruncula. Next to it is the plica semilunairs, and it's what's left of a third eyelid that used to — ready for this? — blink horizontally. It's supposed to have offered protection for our eyes, and some birds, reptiles, and fish have such a thing.</p>Palmaris longus

<p> We don't have much need these days, at least most of us, to navigate from tree branch to tree branch. Still, about 86 percent of us still have the wrist muscle that used to help us do it. To see if you have it, place the back of you hand on a flat surface and touch your thumb to your pinkie. If you have a muscle that becomes visible in your wrist, that's the palmaris longus. If you don't, consider yourself more evolved (just joking).</p>Darwin's tubercle

<p> Yes, maybe the shell of you ear does feel like a dried apricot. Maybe not. But there's a ridge in that swirly structure that's a muscle which allowed us, at one point, to move our ears in the direction of interesting sounds. These days, we just turn our heads, but there it is.</p>Goosebumps

<p>It's not entirely clear what purpose made goosebumps worth retaining evolutionarily, but there are two circumstances in which they appear: fear and cold. For fear, they may have been a way of making body hair stand up so we'd appear larger to predators, much the way a cat's tail puffs up — numerous creatures exaggerate their size when threatened. In the cold, they may have trapped additional heat for warmth.</p>Tailbone

<p> You've probably seen how non-human primate babies grab onto their parents' hands to be carried around. We used to do this, too. So still, if you touch your finger to a baby's palm, or if you touch the sole of their foot, the palmar grasp reflex will cause the hand or foot to try and close around your finger.</p>Other people's suggestions
