The Advantage of High School Sweethearts
Helen E. Fisher, Ph.D. biological anthropologist, is a Senior Research Fellow at The Kinsey Institute at Indiana University, and a Member of the Center For Human Evolutionary Studies in the Department of Anthropology at Rutgers University. She has written six books on the evolution, biology, and psychology of human sexuality, monogamy, adultery and divorce, gender differences in the brain, the neural chemistry of romantic love and attachment, human biologically-based personality styles, why we fall in love with one person rather than another, hooking up, friends with benefits, living together and other current trends, and the future of relationships — what she calls: slow love.
Question: What is love?
Helen Fisher: Love is a lot of things to a lot of different people, but I do think that we all have inherited these three basic brain systems for mating and reproduction; the sex drive, romantic love, and deep feelings of attachment. But when you take a look around the world at world poetry, I think poetry is a very good litmus test. I think poetry is a very good indication of the emotions. And all over the world you see the same descriptions of romantic love. For example, the first thing that happens when you fall in love is a person takes on what I call “special meaning.” As George Bernard Shaw said, He said, “Love consists of overestimating the differences between one woman and another.” And indeed, we do. And then you focus on this person. That person’s car is different from any other car in the parking lot. The street they live on is different, the music they like is different. Everything about them is special and you focus on it. In fact, before I began putting people into the brain scanner, I would ask them, what do you not like about your sweetheart? And they would list what they didn’t like and then they would sweep that aside and just focus on what they did like.
Another basic characteristic of romantic love is intense energy. You can walk all night and talk til dawn, real mood swings, elation when things are going well, crashing into terrible despair when you don’t get an email, or don’t get a call, real possessiveness, it’s called “mate guarding” among animals. Most people don’t care if they’re casually sleeping with somebody. They don’t care if that person is sleeping with somebody else, but when you’re in love, you really care.
But the three main characteristics of romantic love are: intense craving for emotional union with this person. You like to sleep with them, but real emotional union with them, and intense motivation to win them, what people will do when they’re in love. And last, but no least, obsessive thinking. You can’t stop thinking about this person. Somebody is camping in your head. It’s also quite uncontrollable. Stendahl once said, “Love is like a fever. It comes and goes quite independently of the will.” And indeed it does. It just visits you. The brain system becomes triggered and you’re off to the races.
Question: Does passion diminish after a certain amount of years?
Helen Fisher: I think that most people believe that romantic love dies after a certain number of weeks, months, or years. But my colleagues and I have actually proved that wrong. The first author on our most recent brain scanning study is Bianca Casavedo. And Bianca, and the rest of us, wanted to see what happens in the brain among people who report that they are still in love, not loving, but in love with somebody after an average of 21 years of marriage. And so, in New York, we put 17 people who said they were still in love with their spouse into the brain scanner and we found exactly the same activity in this tiny little factory near the base of the brain that we found among those who had just fallen madly in love in the ventral tegmental area.
So, you can sustain romantic love long-term. But we did find one difference. When you just fallen in love, we find activity in a brain region associated with anxiety, and among those who were in love long-term, that has disappeared, and instead you now feel a sense of calm. And so what I think is going on among people who are in love long-term is they still want that man to come home for dinner and they still want to sit down and talk about the day and they still want to go on that vacation together, and they want to share their lives, they’re not thinking of divorce, they feel that sense of romance and tingling sensation. But if they don’t get a phone call at lunchtime, they don’t crumble in a corner and cry. That anxiety is replaced with calm.
Question: What are the differences in relationships that start in high school versus later in life relationships?
Helen Fisher: I haven’t studied the differences in the brain between those who met in high school and those who met later in life. But I do think that those who met in high school have some wonderful advantages. And that is that they know each other’s parents, they knew the dog that she grew up with and his younger sister, and the fact that he was a high school star and that she was wonderful at the Jitter Bug, at dancing. You know, they have all those memories that are wonderful. This is one of the reasons I think that, there’s a real trend right now of older people divorcing and then finding their first love on the Internet and falling in love with somebody who they really were in love with in high school. And they do have that advantage of this understanding of the house they grew up in, the kind of car that he drove, etc., etc.; the kinds of things that really bring continuity.
As a matter of fact, I’ve interviewed some of these people who had reconnected much later. And one of them was a couple, they were probably both in their 60’s, and I asked him whether she had changed at all. And he said, “Not at all.” And then I saw photographs of the two of them in high school standing in front of a Christmas tree and I could see them clearly now. And they were so dramatic – I mean they both gained 100 pounds, they were so dramatically different. But once you get a vision of who this person is, if you can hold on to this, you will create a happy relationship.

Students who think the world is just cheat less, but they need to experience justice to feel that way.
- Students in German and Turkish universities who believed the world is just cheated less than their pessimistic peers.
- The tendency to think the world is just is related to the occurence of experiences of justice.
- The findings may prove useful in helping students adjust to college life.
The world is just? That’s news to a lot of people.<p>The study is the most recent addition to a long line of work focusing on the belief in justice, our behavior, and our reactions to evidence that might suggest injustice occasionally occurs. This study focuses on a personal belief in a just world, (PBJW) rather than a general belief in a just world (GBJW). The difference between them must be highlighted.</p><p>GBJW is the stance that justice prevails all over the world and that people tend to get what they deserve. PBJW is more focused on the individual's social environment and their belief that they tend to be treated justly. While several studies show PBJW correlates with a higher sense of well-being and a variety of other positive effects, a high GBJW is associated with less life satisfaction, negative behavior, and callousness towards the suffering of <a href="https://link.springer.com/book/10.1007%2F978-1-4939-3216-0" target="_blank">others</a>. This study controlled for GBJW, and focused on PBJW as much as possible. </p><p>To assure that culture was not a factor, the study included students at universities in both Germany and Turkey. </p><p>The researchers gave students at the four participating universities a series of questionnaires that asked if they ever cheated in class, if they perceived the world to be just, if they though that justice always prevailed everywhere, their tendencies towards socially appropriate behavior, their life satisfaction, and if they felt like they were treated justly by their teachers and fellow students. </p><p>The answers were statistically analyzed for relationships. While some of the connections seem trivially true, others were surprising. <strong></strong></p><p>PBJW turned out to only be an indirect predictor of if a student was likely to cheat. Both a belief in a just world and a lower likelihood of cheating were mediated by the justice experiences of the students, with more of these positive experiences lowering the rate of cheating and improving their belief in justice. This was also associated with higher levels of life satisfaction. </p><p>These effects existed across all demographics in both countries. </p>
What does this mean? Is a belief in justice a self-fulfilling prophecy?<iframe width="730" height="430" src="https://www.youtube.com/embed/6oMv-azHNCA" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p>In a way, it seems to be. People who have reason to think the world is just to them tend to interpret events in a way to sustain that belief and behave in a just manner. In a larger sense, the take away from this study is that experiences of justice, both from peers and instructors, is vital to student's wellbeing and understanding that the rules that exist about cheating are part of a larger, legitimate, system. </p><p>The researchers, citing previous studies on the perception of justice, note that "justice experiences (1) signal that university students are esteemed members of their social group, which in turn conveys feelings of belonging and social inclusion and (2) motivate them to accept and observe university rules and norms. These cognitive processes may thus strengthen their well-being and decrease the likelihood that they cheat."</p><p>The authors also suggest that if you want people (not only students) to act justly; consider treating them with "civility, respect, and dignity."</p><p>Sometimes, all it can take to help somebody act virtuously is to treat them well. Likewise, people treated harshly can rarely find reason to play by rules that don't protect them. The findings of this study will certainly add to the literature on how we perceive justice in the world around us, but might also help us remember that there are real consequences to our actions which can be much larger than we imagine. <strong></strong></p>
This could change how researchers approach vaccine development.
- The reason children suffer less from the novel coronavirus has remained mysterious.
- Researchers identified a cytokine, IL-17A, which appears to protect children from the ravages of COVID-19.
- This cytokine response could change how researchers approach vaccine development.

At least one company, Moderna, <a href="https://www.businessinsider.com/coronavirus-vaccine-for-kids-moderna-plans-pediatric-trial-2020-9" target="_blank">hopes to begin testing</a> vaccines in pediatric volunteers by year's end.</p><p>Innate immune response is especially high during childhood (compared to adaptive immunity). This makes evolutionary sense: nature wants an animal to survive until its ready to procreate. Turns out the children in the study possessed high levels of cytokines that boost their immune response. The biggest impact is made by IL-17A, which appears to protect the youngest cohort from the ravages of the coronavirus. </p><p>While both age groups produced antibodies to fight off the infamous spike protein, adults that produce neutralizing antibodies actually suffer a <em>worse</em> fate. Herold says this "over-vigorous adaptive immune response" might promote inflammation, triggering acute respiratory distress syndrome (ARDS). </p><p>This matters for vaccine development. As Herold says, </p><p style="margin-left: 20px;">"Our adult COVID-19 patients who fared poorly had high levels of neutralizing antibodies, suggesting that convalescent plasma—which is rich in neutralizing antibodies—may not help adults who have already developed signs of ARDS. By contrast, therapies that boost innate immune responses early in the course of the disease may be especially beneficial."</p><p>Herold says current vaccine trials are focused on boosting neutralizing-antibody levels. With this new information, researchers may want to work on vaccines that boost the innate immune response instead. </p><p>With <a href="https://www.nytimes.com/interactive/2020/science/coronavirus-vaccine-tracker.html" target="_blank">at least 55 vaccine trials</a> underway, every piece of data matters. </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" rel="noopener noreferrer">Substack</a>.

Identifying 2020 SO<p>The first clue 2020 SO isn't your ordinary asteroid is its exceptionally low velocity. It's traveling much more slowly that a typical asteroid — their <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank">average rate of travel</a> <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank" rel="noopener noreferrer"></a>is 18 kilometers (58,000 feet) per second. Even <a href="https://en.wikipedia.org/wiki/Moon_rock" target="_blank">moon rocks</a> sent careening into Earth orbit by impacts on the lunar surface outpace pokey 2020 SO.</p><p>For another thing, 2020 SO has an orbital path very similar to Earth's, lasting about one Earth year. It's also just slightly less circular than our own orbit, from which it's barely tilted off-axis.</p><p>So, what is it? <a href="https://cneos.jpl.nasa.gov/ca/" target="_blank">NASA estimates</a> that the object has dimensions very reminiscent of a discarded Centaur rocket stage from the <a href="https://en.wikipedia.org/wiki/Surveyor_2" target="_blank" rel="noopener noreferrer">Surveyor 2 mission</a> that landed an unmanned craft on the moon. Back in the day, rocket stages were jettisoned as craft were aimed toward their desired position. This stuff, if released high enough, remains in space. It appears that this Centaur rocket, launched in September 1966, is now making its way back homeward, at least for a little bit.</p><p>When 2020 SO arrives at its closest point in December, the rocket is expected to be about 50,000 kilometers from Earth. Its next closest approach is much further: 220,000 kilometers, in February 2010.</p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQzMDk3NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyODg1MTQ1MX0.HGknDwqp0GmeuczKY_AS7vrPG7KMFUc_XO95tNoI2xo/img.jpg?width=980" id="e5cda" class="rm-shortcode" data-rm-shortcode-id="85eb1f790d8c3ee5b261f7ba13eaa5e1" data-rm-shortcode-name="rebelmouse-image" alt="Centaur rocket stage" />

What we may be able to learn<p>Earthly space programs being as young as they are, scientists would love to know what's happened to our rocket during a half century in space.</p><p>While 2020 SO won't get close enough to drop into our atmosphere, its slow progress has scientists hopeful that they'll still get some kind of a decent look at it.</p><p>Spectroscopy may be able to reveal what the rocket's surface is like now — has any of its paint survived, for example? Of course, being out in space, it's likely to have been hit by lots of dust and micrometeorites, so the current state of its surfaces is also of interest. Experts are curious to know how reflective the rocket is at this point, valuable information that can help planners of future long-term missions anticipate how well a craft out in space for extended periods will remain able to reflect sunlight.</p>

Credit: National Cancer Institute/Unsplash<p>Moffat and his colleagues decided to investigate and identify genes within cancer cells that help them defeat treatment. Co-lead author Keith Lawson of Moffat's lab explains that "it's important to not just find genes that can regulate immune evasion in one model of cancer, but what you really want are to find those genes that you can manipulate in cancer cells across many models because those are going to make the best therapeutic targets."</p><p>To accomplish this, the researchers, working with scientists at <a href="https://www.agios.com" target="_blank">Agios Pharmaceuticals</a> in Cambridge, Massachusetts, first exposed cells from breast, colon, kidney and skin cancer tumors to T cells in lab dishes. This established a baseline of their responses to treatment. Next, using CRISPR, the scientists went through the cells, exhaustively turning off one gene at a time to determine its role in immunotherapy resistance by comparing the cells' response to the T cells compared to their original baseline response.</p><p>The team identified 182 "core cancer intrinsic immune evasion genes" that affected the cells' response to T cells. The fact that some of the identified genes were already known to be involved in resistance provided the researchers with some confidence that they were on the right track.</p><p>Still, many of the genes they ID'ed had not been previously implicated. "That was really exciting to see because it means that our dataset was very rich in new biological information," says Lawson.</p>
