Neil deGrasse Tyson: How science literacy can save us from the internet
If you understand when and how to ask questions, you possess an effective inoculation against charlatans.
Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. He is the first occupant of the Frederick P. Rose Directorship of the Hayden Planetarium. His professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way. Tyson obtains his data from the Hubble Space Telescope, as well as from telescopes in California, New Mexico, Arizona, and in the Andes Mountains of Chile.Tyson is the recipient of nine honorary doctorates and the NASA Distinguished Public Service Medal. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid "13123 Tyson".
Tyson's new book is Letters From an Astrophysicist (2019).
NEIL DEGRASSE TYSON: I think no one would give up the internet today, in spite of the problems that it has presented us. It started out oh, this is kind of fun. We can watch cat videos all day or that most of the information that came across was instructive or humorous or enlightening. It didn't start turning mean until a few years in, maybe five or ten years ago. Certainly definitely beginning at least five years ago where people see it as a way to tribalize us. You don't agree with my opinion, you're wrong, and I'm going to fight you for it. I didn't grow up in that environment. I don't think anyone else did either. It was you have a different opinion? Cool. Tell me about it. Let's go have a beer, we'll talk about it. Not I will argue with you until you are dead unless you agree with my opinion. See something's not right there. And everybody's got an opinion and so there it goes. The internet is this clearinghouse of opinions but nothing gets cleared. Opinions ossify, making it a rather rigid place to navigate.
We have access to more information than ever before. That's a good thing. It gives good information some hope. But are we trained? Do we have the tandem training to know whether the information you just were exposed to is legitimate, is it real, is it false, is it true? You can't just hand people new kinds of information without expecting them to be confused by it without some training that would have occurred before it. Maybe all school curricula should be how to determine reliable sources and how not. How to know when it's not reliable. Is that in the curriculum? Not last I looked. Maybe in journalism school but not in K-12. Not in college, I haven't seen much of it. So yeah, we need practice. Better yet we need science literacy. Science literacy empowers you to know when someone else is full of shit. And it's simple. What is science literacy? It's understanding how things work. How physiology works. How chemistry works. How physics works. Engineering.
All of this. You don't have to be an engineer or be a scientist. Just understand how certain basic systems work so that when someone is ready to sell you homeopathic medicine where they've diluted the active ingredients from the water so that there's no molecules left in the water and they sell that to you and they're telling you that the water remembers the medicine that used to be in it. And you're going to hand money to someone for that? I'm not going to complain to you. I'm going to say let's go together and look at how you were trained. Let's look at the syllabus that you were handed when you were in school. Here's where you're missing a few things. Here's where you're missing how to ask questions. Science is not a satchel of knowledge. It's a way of querying nature and a way of querying other people who are making claims about nature. That's where the empowerment comes from. It's an inoculation against charlatans. That's how you're going to know the difference going forward.
- The internet has become a tool to tribalize us, a place where opinions become identities in a fight to the death of who's right and who's wrong.
- As information continues to flow in, many of us lack the training to effectively sort opinion from fact. This leads to widespread disinformation.
- We need science literacy. With an understanding of how things work, or how to question how things work, we empower ourselves to discover the truth.

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.
A time for sleep<div class="rm-shortcode" data-media_id="Mt29uUqI" data-player_id="FvQKszTI" data-rm-shortcode-id="931343dee3c02121445e51e94ba22446"> <div id="botr_Mt29uUqI_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/Mt29uUqI-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/Mt29uUqI-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/Mt29uUqI-FvQKszTI.js"></script> </div> <p>Previous studies had already suggested a link between persistent nightmares in childhood and psychosis and borderline personality disorder (BPD) by adolescence, but researchers at the University of Birmingham's School of Psychology wanted to see if a similar connection existed between these mental disorders and other childhood behavioral sleep problems.</p><p>To do this, they scoured data from the Avon Longitudinal Study of Parents and Children, a longitudinal cohort study that followed approximately 14,000 children born in Avon, England, in the early 1990s. The study followed the children for more than 13 years. During that time, mothers filled out questionnaires asking about the children's lives. Factors looked at included housing, parenting, nutrition, physical health, mental wellbeing, environmental exposures, and so on. </p><p>The cohort study inquired about sleep routines, sleep duration, and awakening frequency when the children were 6, 18, and 30 months old, and then again at 3.5, 4.8, and 5.8 years. It also assessed mental health in adolescence using semi-structured interviews, such as the Psychosis-Like Symptom Interview.</p><p>"We know that adolescence is a key developmental period to study the onset of many mental disorders, including psychosis or BPD. This is because of particular brain and hormonal changes which occur at this stage," <a href="https://www.birmingham.ac.uk/staff/profiles/psychology/marwaha-steven.aspx" target="_blank">Steven Marwaha</a>, professor of psychiatry at Birmingham and senior author on the study, <a href="https://www.sciencedaily.com/releases/2020/07/200701125431.htm" target="_blank">said in a release</a>. "Sleep may be one of the most important underlying factors—and it's one that we can influence with effective, early interventions, so it's important that we understand these links."</p><p>After compiling the data, the researchers discovered an association between children with irregular sleeping patterns and teenagers with <a href="https://www.mind.org.uk/information-support/types-of-mental-health-problems/psychosis/about-psychosis/" target="_blank">psychotic experiences</a>—that is, episodes when the person perceives reality differently than those around them. Even when depression at 10 years old was considered as a mediating factor, their findings still suggested "a specific pathway between these childhood sleep problems and adolescent psychotic experiences." </p><p>Toddlers with shorter nighttime sleep duration and late bedtimes were likewise associated with a <a href="https://www.nimh.nih.gov/health/topics/borderline-personality-disorder/index.shtml" target="_blank">borderline personality disorder</a>—a disorder marked by a pattern of varying moods, self-images, and behaviors—in their teenage years. Depression at age 10 did not mediate this particular association, suggesting a separate and more specific pathway. </p>
A more restful tomorrow<p>While the sample size was large and mental health was assessed with a validated interview, there nevertheless remain limitations to this data. For starters, sleep habits were based on mothers' reports. Because they came from memory, versus a more direct observation method such as actigraphy, these data may be prone to imperfect recollection and reporting error. There are also many confounders that could be secretly nudging the results, such as family conditions, prenatal medicines, and a host of environmental factors. Finally, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6024884/#:~:text=Sleep%20difficulties%20in%20youth%20with,fear%20of%20dark%20%5B13%5D." target="_blank">the relationship between sleep problems and mental disorders</a> is both complex and two-way.</p><p>As such, the study shows an association between poor childhood sleep later mental disorders but does not prove a causal link. Parents need not worry that a string of nightmares or the eternal struggle settle into bed will be the first ingredients in a witches' brew of debilitating mental disorders. The goal of the study, the researchers point out, is not to create undue worry but improve our ability to recognize the signs of at-risk children and deliver necessary interventions earlier.</p><p>"The results of this study could have important implications for helping practitioners identify children who might be at higher risk for psychotic experiences or BPD symptoms in adolescence, and potentially lead to the design of more effectively targeted sleep or psychological interventions to prevent the onset or attenuate these mental disorders," Isabel Morales-Muñoz, the study's lead researcher, <a href="https://www.healio.com/news/psychiatry/20200702/childhood-sleep-problems-linked-to-adolescent-psychosis-borderline-personality-disorder#:~:text=Sleep%20problems%20during%20early%20childhood,study%20published%20in%20JAMA%20Psychiatry." target="_blank">told Healio Psychiatry</a><u>.</u></p><p>If a parent reading this is worried that their child's sleep patterns are deleterious, the take away should not be despair over an unyielding fate. It should be to seek professional help as soon as possible to begin improving sleep duration and quality. Even if you aren't worried, it's worth remembering that childhood experiences lay the foundation for a lifetime of salubrious sleeping habits. It's so much more than beauty rest.</p>

Are we genetically inclined for superstition or just fearful of the truth?
- From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
- "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
- Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.
