Can passenger airships make a triumphantly 'green' comeback?
Large airships were too sensitive to wind gusts and too sluggish to win against aeroplanes. But today, they have a chance to make a spectacular return.
Vegans and vegetarians often have nutrient deficiencies and lower BMI, which can increase the risk of fractures.
- The study found that vegans were 43% more likely to suffer fractures than meat eaters.
- Similar results were observed for vegetarians and fish eaters, though to a lesser extent.
- It's possible to be healthy on a vegan diet, though it takes some strategic planning to compensate for the nutrients that a plant-based diet can't easily provide.
Comparison of fracture cases by diet group
Credit: Tong et al.<p>The results showed that vegans were especially vulnerable to hip fractures, suffering 2.3 times more cases than meat-eaters. Vegetarians and pescatarians were also more likely to suffer hip fractures, though to a lesser extent.</p><p>One explanation may be that non-meat eaters consume less calcium and protein. Calcium helps the body build strong bones, particularly before age 30, after which the body begins to lose bone mineral density (though consuming enough calcium through diet or supplement can <a href="https://ods.od.nih.gov/factsheets/Calcium-Consumer/" target="_blank">help offset losses</a>). Lower bone mineral density means higher risk of fracture.</p><p>Protein seems to help the body absorb calcium, <a href="https://www.bonejoint.net/blog/did-you-know-that-certain-foods-block-calcium-absorption/#:~:text=Historically%2C%20nutritionists%20have%20warned%20that,may%20increase%20intestinal%20calcium%20absorption." target="_blank" rel="noopener noreferrer">when consumed in normal levels</a>. The recent study, along with past research, shows that people who don't eat meat tend to have lower levels of both protein and calcium. When the researchers accounted for non-meat eaters who supplemented their diets with calcium and protein, fracture risk decreased, but still remained significant.</p>

In the new study, vegans with a low BMI were especially likely to suffer hip fractures. That might be because having more body mass provides a cushioning effect when people fall.</p><p>Still, the study has some limitations. For one, White European women were overrepresented in the sample. The researchers also didn't collect precise data on the type of calcium or protein supplementation, diet quality or causes of fractures.</p><p>Another complicating factor: Producers of vegan products, such as plant-based milk, are increasingly fortifying foods with nutrients like calcium and protein, so modern vegans are potentially at lower risk of deficiency.</p><p>The researchers wrote that their findings "suggest that bone health in vegans requires further research."</p>
Staying healthy on a vegan diet<p>So, does a vegan diet necessarily lead to worse bone health? Not necessarily. But it's safe to say that people who don't consume meat, dairy and eggs should be extra vigilant about consuming enough essential nutrients. That can be harder than it seems.<br></p><p>One major reason is that the body generally has an easier time absorbing nutrients from animal foods than plant-based products. So, while a salad could contain the same amount of calcium as a glass of milk, the body absorbs more calcium when you drink milk. What's more, there are some molecules and <a href="https://www.healthline.com/nutrition/7-nutrients-you-cant-get-from-plants#5.-Docosahexaenoic-acid-(DHA)" target="_blank">nutrients you simply can't get from plants</a>.</p><p>As such, many vegans round out their diets with supplements, including zinc, iron, iodine, long-chain omega-3s, and vitamins D, K-2, and B-12, to name a few. If you're on a vegan diet or considering making the switch, it's probably best to consult a dietician, and to make sure you maintain a <a href="https://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/english_bmi_calculator/bmi_calculator.html" target="_blank" rel="noopener noreferrer">healthy BMI</a>.</p>
Never made a turkey before? Don't worry, science can help.
- This year, many people will be making a Thanksgiving dinner for the first time. It's often harder than it looks.
- Luckily, an online calculator website has one just for thawing turkey, and can explain why you need to wait so long.
- The website has other calculators as well, for needs you didn't know you had.
How to thaw a turkey using science!<p> The Omni Calculator <a href="https://www.omnicalculator.com/" target="_blank" rel="noopener noreferrer">website</a> is home to calculators that can determine many things, including how <a href="https://www.omnicalculator.com/other/sunscreen" target="_blank" rel="noopener noreferrer">long you can be in the sun safely</a>,<a href="https://www.omnicalculator.com/other/sunscreen" target="_blank" rel="noopener noreferrer"> </a>to the odds of your town having a <a href="https://www.omnicalculator.com/other/white-christmas" target="_blank" rel="noopener noreferrer">white Christmas</a>. It now has a dedicated tool for finding how long it will take you to prep your <a href="https://www.omnicalculator.com/food/turkey-thawing" target="_blank" rel="noopener noreferrer">turkey</a> in time for a socially distanced holiday. The <a href="https://www.omnicalculator.com/food/turkey-thawing" target="_blank">Turkey Thawing Calculator </a>was created by Jagiellonian University cognitive science graduate Maria Kluziak with the help of Wojciech Sas, a Ph.D. candidate in molecular magnetism and nanostructures at the Institute of Nuclear Physics in Poland. </p><p>The fundamental problem is that you need to add heat to the frozen bird to unfreeze it without also encouraging the growth of bacteria. To do this, you have to put the turkey somewhere where it will heat up slowly and evenly. There is a trick, though; this can take a long time because of the amount of energy involved. Exactly how long you need to spend on it can be hard to determine if you've never done it before. </p><p>This is where practical, day-to-day science comes in. The processes of heating something are well-studied areas of thermodynamics which we use every day. <br> <br> As Kluziak tells Big Think: </p><p>"If you look closely, you'll notice how we're all surrounded by numbers. Yet most of the time people choose to go with their intuition while making day-to-day decisions. We, as scientists and experts in our own fields, are trying to build a world where people make better, more informed decisions backed by concrete science - Using physics to chill drinks, math to find out how much pizza to get, and even calculating how much groceries are enough to survive a quarantine. It works."</p>
So, how do I thaw a turkey?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDgwNjA0Ny9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY0NzI3NTQzN30.hr2xv0tzFU_12bA-wwKwBPv0Tou_ZcdMoF1VDlov-0k/img.png?width=980" id="07afc" class="rm-shortcode" data-rm-shortcode-id="522a8b8370fecb9dcb3bf483adea6fa5" data-rm-shortcode-name="rebelmouse-image" />
Credit: Omni Calculator<p> By slowly exposing the turkey to cool air or water, it heats up to a point where the bird is above freezing but not so warm that bacteria will start multiplying. Two of the safe ways to do this stand above all others; you can thaw it in the refrigerator or the sink.<br> <br> Using a refrigerator can take days; the calculator creators suggest a day for every four pounds of bird. Doing it with cold water in the sink is faster, needing only two hours per pound, but requires that you drain and refill the sink with new, cold water every thirty minutes. The ideal temperature during thawing shouldn't exceed 39°F/4°C.</p><p>"In our thawing model, we use a scientific approach, which is based on the use of heat transfer equations," the scientists write. "Since these types of problems are, in general, very complicated, we use some approximations, which allow us to estimate the thawing time with reasonable accuracy. As a result, you can see how the average temperature of the turkey changes in time." </p><p>You can learn more about the equations and get tips on using the calculator <a href="https://www.omnicalculator.com/food/turkey-thawing" target="_blank" rel="noopener noreferrer">here</a>. You can also learn why you shouldn't use a hairdryer or a tub full of hot water to do the job. <br> <br> One of the best parts of science is that its findings are often universally applicable. If you understand why something works in one case, you can use it everywhere else. Kluziak reminds us why this might be great for cooking:<br> <br> "The rules that govern the process of thawing are roughly the same for every kind of food, what's different are the numbers that determine the more specific things like thawing time. The general ideas remain the same regardless of the food, and I would say they are pure common sense. For example, if you're defrosting food, don't do it at room temperature to avoid bacteria - this is true every time!"<strong></strong></p><p><strong> </strong>Whoever said you'd never use the science you learned in high school at home didn't understand how often we use physics—this calculator remind us that it is everywhere. So fear not, ye first-time turkey chefs! Science can help you have your main course and eat it too. </p>
