Hey Bill Nye! What Do You Consider Your Greatest Achievement?
Bill Nye is the CEO of The Planetary Society, has his own Netflix show, flew on Air Force One with President Obama, and has at least six honorary doctorate degrees. But there's one thing that makes him prouder than all that combined.
Bill Nye
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.
Tracey: Dear Bill Nye. My name is Tracey, and as of today it is my 19th birthday, and I’m pursuing my education in the sciences thanks to the influence of worldly educators such as yourself. My question to you is: what do you think is the most beneficial thing a scientist can do for the community, and what do you consider your greatest accomplishment as a scientist and an educator? All the best, and thank you for your contributions to the generations ahead of you.
Bill Nye: Tracey. I’m delighted that you are pursuing a career in science. We need as many scientifically literate people as we can in our society so that when it’s time to vote and make decisions about our future we do it in an informed way with science as the background. So thank you. This is fabulous.
As far as my contribution, that’s a very nice question. I think it’s getting young people excited about science so that in the future we’ll have scientifically literate people. And what we want is for people — it’s not just the facts. The facts are great. They often change as we learn more, but the big thing is to get the process of science.
You make an observation, your eyebrows go up, you say to yourself, "My goodness, what caused that?" And then you come up with an idea or a hypothesis of what made that effect happen, this phenomenon that you observed. And then you come up with a way to test it. You test it and then you see what happened and compare what you thought would happen with what did happen. And you’re comparing your hypothesis to the outcome.
If we can get that across to as many people as possible we can, Tracey, dare I say it: we can change the world. That’s a great question.
Bill Nye has many feathers in his cap — he's the CEO of The Planetary Society, has a brand-new Netflix show, flew on Air Force One with President Obama, has at least six honorary doctorate degrees and two books to his name — but there's thing one he's most proud of, and he shares it with Tracey, a 19-year-old student just beginning her science studies at college. As she steps into a lifelong pursuit of science, Nye advises her on the greatest contribution scientists can make to their community. Dropping awe-inspiring facts and publishing groundbreaking findings are exciting parts of being a scientist but the greatest contribution a scientist can make is to educate people — especially kids from a young age — about the scientific method. Carl Sagan, Bill Nye's mentor, can explain this in better words than anyone: "Science is more than a body of knowledge, it’s a way of thinking, a way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us something is true, to be skeptical of those in authority, then we’re up for grabs for the next charlatan — political or religious — who comes ambling along. The people have to be educated, and they have to practice their skepticism and their education otherwise we don’t run the government, the government runs us." Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.

Coronavirus
- Anxiety and depression rates are spiking in the LGBTQ+ community, and especially in individuals who hadn't struggled with those issues in the past.
- Overall, depression increased by an average PHQ-9 score of 1.21 and anxiety increased by an average GAD-7 score of 3.11.
- The researchers recommended that health care providers check in with LGBTQ+ patients about stress and screen for mood and anxiety disorders—even among those with no prior history of anxiety or depression.
<p>In the midst of the COVID-19 pandemic, anxiety and depression rates are spiking in the LGBTQ+ community, especially in individuals who hadn't struggled with those issues in the past, say researchers. </p><p>"What I was hearing at the beginning of the pandemic was that people who were already anxious were more anxious than ever, and we didn't find that," <a href="https://www.usnews.com/news/health-news/articles/2020-07-06/coronavirus-ups-anxiety-depression-in-the-lgbtq-community" target="_blank">said researcher Annesa Flentje</a>, an assistant professor in the University of California, San Francisco School of Nursing, in a university press release. "In looking at averages across the LGBTQ+ population, we found the greatest changes in anxiety were among people who weren't anxious prior to the pandemic." </p>
Study findings
<p>For the study, <a href="https://link.springer.com/article/10.1007/s11606-020-05970-4" target="_blank">published in the Journal of General Internal Medicine</a><em>, </em>Flentje and her team evaluated survey responses from nearly 2,300 individuals who identified as being in the lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community. Most of the participants were white, while nearly 19 percent identified as a racial or ethnic minority. Multiple genders were represented with cisgender women (27.2 percent) and men (24.6 percent) making up a majority of the participants. Sixty-three percent had been assigned female at birth. For the most part, participants identified their sexual orientations as queer (40.3 percent), gay (36.5 percent), and bisexual (30.3 percent).</p><p>The JGIM study participants were recruited from the 18,000-participant <a href="https://pridestudy.org/" target="_blank">PRIDE Study</a> (Population Research in Identity and Disparities for Equality), which is the first large-scale, long-term national study focusing on American adults who identify as LGBTQ+. It conducts annual questionnaires to understand factors related to health and disease in this population. </p><p>Participants filled out an annual questionnaire (starting in June 2019) and a COVID-19 impact survey this past spring. Flentje noted that on an individual level, some people may not have experienced a big change in anxiety or depression levels, but for others there was. Overall, depression increased by a <a href="https://patient.info/doctor/patient-health-questionnaire-phq-9" target="_blank">PHQ-9 score</a> of 1.21, putting it at 8.31 on average. Anxiety went up by a <a href="https://www.mdcalc.com/gad-7-general-anxiety-disorder-7" target="_blank">GAD-7</a> score of 3.11 to an average of 8.89. Interestingly, the average PHQ-9 scores for those who screened positive for depression at the first 2019 survey decreased by 1.08. Those who screened negative for depression saw their PHQ-9 scores increase by 2.17 on average. As for anxiety, researchers detected no GAD-7 change among the study participants who screened positive for anxiety in the first survey, but did see an overall increase of 3.93 among those who had initially been evaluated as negative for the disorder. </p>Risks among gender and sexual minorities

"This study highlights the need for <a href="https://medicalxpress.com/tags/health+care+professionals/" target="_blank">health care professionals</a> to support, affirm and provide <a href="https://medicalxpress.com/tags/critical+care/" target="_blank">critical care</a> for the LGBTQ community to manage and maintain their mental health, as well as their physical health, during this pandemic."</p>What should health care providers do?
<p>The authors of the study recommend that health care providers check in with LGBTQ+ patients about stress and screen for mood and anxiety disorders in members of that community—even among those with no prior history of anxiety or depression.</p><p>As cases of COVID-19 continue to mount, the sustained social distancing, potential isolation, economic precariousness, and personal illness, grief, and loss are bound to have increased and varied impacts on mental health. Effective treatments may include individual therapy and medications as well as more large-scale coronavirus support programs like peer-led groups and mindfulness practices. </p><p>"It will be important to find out what happens over time and to identify who is most at risk, so we can be sure to roll out public health interventions to support the mental health of our communities in the best and most effective ways," said Flentje.</p>

The mind-blowing science of black holes
What we know about black holes is both fascinating and scary.
13 July, 2020
Videos
- When it comes to black holes, science simultaneously knows so much and so little, which is why they are so fascinating. Focusing on what we do know, this group of astronomers, educators, and physicists share some of the most incredible facts about the powerful and mysterious objects.
- A black hole is so massive that light (and anything else it swallows) can't escape, says Bill Nye. You can't see a black hole, theoretical physicists Michio Kaku and Christophe Galfard explain, because it is too dark. What you can see, however, is the distortion of light around it caused by its extreme gravity.
- Explaining one unsettling concept from astrophysics called spaghettification, astronomer Michelle Thaller says that "If you got close to a black hole there would be tides over your body that small that would rip you apart into basically a strand of spaghetti that would fall down the black hole."
Scientists see 'rarest event ever recorded' in search for dark matter
The team caught a glimpse of a process that takes 18,000,000,000,000,000,000,000 years.

Surprising Science
- In Italy, a team of scientists is using a highly sophisticated detector to hunt for dark matter.
- The team observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
- The half-life of a process is how long it takes for half of the radioactive nuclei present in a sample to decay.
</li></ul>
<p>Scientists have observed an extremely rare particle physics event using a detector that's hunting for dark matter, the mysterious material that physicists have yet to observe.</p><p>In a <a href="https://www.nature.com/articles/s41586-019-1124-4" target="_blank">paper published in </a><a href="https://www.nature.com/articles/s41586-019-1124-4" target="_blank">the journal <em>Nature</em></a>, researchers with the XENON Collaboration said they'd observed the radioactive decay of a substance called xenon-124, an isotope of the element xenon — a colorless and odorless noble gas found in tiny amounts in the atmosphere. The event — a "two-neutrino double electron capture" — has eluded scientists for decades. </p><p>It happens when "two protons in a nucleus are simultaneously converted into neutrons by the absorption of two electrons from one of the atomic shells and the emission of two electron neutrinos." After this occurs, the event shoots out a predictable cascade of X-rays and Auger electrons that scientists look for using an ultra-sensitive detector, buried about 5,000 feet beneath Italy's Gran Sasso mountain where it's shielded from cosmic rays.</p><p style="margin-left: 20px;">"We have shown that we can observe the rarest events ever recorded," Ethan Brown, a professor of physics at Rensselaer Polytechnic Institute and co-author of the study, told <em><a href="https://www.newsweek.com/dark-matter-hunters-observe-rarest-event-ever-recorded-1404823" target="_blank">Newsweek</a></em>. "The key finding is that an isotope formerly thought to be completely stable has now been shown to decay on an unimaginably long timescale."</p><p>How long is that timescale? The team estimated that xenon-124's half-life is about 18 sextillion years — or 18,000,000,000,000,000,000,000 years — which is than one trillion times the age of our universe, according to the team. It's the slowest process ever measured directly, the team wrote in a statement. </p><p style="margin-left: 20px;">"It's an amazing to have witnessed this process, and it says that our detector can measure the rarest thing ever recorded," Brown told <a href="https://www.independent.co.uk/life-style/gadgets-and-tech/news/dark-matter-rarest-ever-event-xenon-half-life-radioactive-discovery-breakthrough-latest-science-a8884896.html" target="_blank"><em>The Independent.</em></a></p>

"This experiment is so sensitive to very rare events that we can make all kinds of other rare physics measurements. One of those is this decay of xenon-124. Although our primary goal was always the discovery of dark matter, we knew there was a good chance we could see this rare decay, so we set out to do so."</p><p>To get that good chance, the team had to expose their detector to a huge amount of xenon atoms by stocking it with 3.2 tons worth of liquid xenon.</p><p style="margin-left: 20px;">"XENON1T is a giant vat of liquid xenon surrounded by light sensors," Brown said. "When dark matter collides in the xenon, or when a radioactive decay occurs inside, we get a tiny flash of light and a little bunch of charge out of the xenon. We measure these with the light sensors and reconstruct everything we can about the original event that caused the light and charge."</p><p>Although the team didn't observe dark matter — which is the primary purpose of the detector — the recent observations could help scientists learn more about neutrinos, one of the least understood fundamental particles in the universe.</p><p style="margin-left: 20px;">"It proves that this XENON detector technology we use for dark matter is much more versatile," graduate student Christian Wittweg, Ph.D student at the University of Münster in Germany, told <em><a href="https://gizmodo.com/dark-matter-detector-makes-incredible-neutrino-observat-1834270148" target="_blank">Gizmodo</a></em>.

Space travel could create language unintelligible to people on Earth
A new study looks at what would happen to human language on a long journey to other star systems.
12 July, 2020
Credit: NASA Ames Research Center.
Surprising Science
- A new study proposes that language could change dramatically on long space voyages.
- Spacefaring people might lose the ability to understand the people of Earth.
- This scenario is of particular concern for potential "generation ships".
<p>Given the mounting crises of 2020, wouldn't it be nice to just get on a giant spaceship and leave this troubled planet behind? While we don't yet have a surefire candidate for the new Earth, and our tech is still probably decades if not centuries behind, proposals and achievements in interstellar travel are stacking up. A new study makes the fascinating case that if a group of humans was to venture out on a space journey that lasted generations, their language would likely change. It could evolve into something the people of the original Earth would not understand.</p><p>Let's say, a contingent of people boards a so-called "<a href="https://www.universetoday.com/144894/what-is-a-generation-ship/" target="_blank">generation ship</a>," a fully-stocked world-onto-itself spaceship that can sustain generations of humans in space, slowly traversing the heavens towards another possibly inhabitable planet like <a href="https://www.eso.org/public/news/eso1629/" target="_blank">Proxima b</a> in the Proxima Centauri star system. We cannot yet build such a ship, which might have to fly for thousands of years, unless we invent some type of warp-drive or use antimatter, as has been imagined in science fiction, but there have been some initial <a href="https://www.universetoday.com/144894/what-is-a-generation-ship/" target="_blank">studies</a> on the subject. </p>
<p>Such a journey could be subject to a variety of dangers and unforeseen circumstances like viruses, asteroids, computer malfunctions, you name it. New research, carried out by linguistics professors <span style="background-color: initial;"><strong>Andrew McKenzie</strong> from the University of Kansas and <strong>Jeffrey Punske </strong>of Southern Illinois University</span>, shows what might also happen is that the language of the travelers would mutate. The study highlights the fact that when communities become isolated from each other, conditions are ripe for language to transform. Over time, the spacefaring colonizers would not be able to able to understand their original language.</p><p>In the study, the linguists use examples of effects from long-distance voyages on Earth, like the changing languages of Polynesian island explorers, to show how much language can change, even within one's lifetime.</p><p>Professor McKenzie described a likely (and somewhat sad) scenario in a <a href="http://news.ku.edu/2020/06/30/without-care-lost-space-could-mean-lost-translation" target="_blank">press release</a>:</p>
<blockquote>"If you're on this vessel for 10 generations, new concepts will emerge, new social issues will come up, and people will create ways of talking about them," McKenzie explained, "and these will become the vocabulary particular to the ship. People on Earth might never know about these words, unless there's a reason to tell them. And the further away you get, the less you're going to talk to people back home. Generations pass, and there's no one really back home to talk to. And there's not much you want to tell them, because they'll only find out years later, and then you'll hear back from them years after that."</blockquote>

So it's possible, given the distance, and the dwindling reasons to communicate, that both parties might simply not be able to speak each other as time passes.</p><p>One way to prevent this issue – have a member of the crew trained in linguistics or make other accommodations to remember the language of Earth. Thinking even further ahead, the professors propose that each new ship of people coming over to a faraway space colony would essentially contain "linguistic immigrants" and an effort would have to be made to train them in the changed language to help them avoid discrimination.</p><p>In case you're deadset on going to Proxima b, <a href="https://arxiv.org/ftp/arxiv/papers/1806/1806.03856.pdf" target="_blank">recent research</a> found that using currently-imaginable-tech such a trip would take <strong>6300</strong> years and would need to start out with a crew of at least <strong>98</strong> people.</p><p>Check out the study, "<a href="https://doi.org/10.5281/zenodo.3747353" target="_blank">Language Development During Interstellar Travel</a>" in Acta Futura, the journal of the European Space Agency's <a href="https://www.esa.int/gsp/ACT/index.html" target="_blank">Advanced Concepts Team</a>.</p>
