Top Video of 2016 #8: ‘Hey Bill Nye, Could the Government Be Hiding Extraterrestrials From Us?’
Peel off your tin-foil hat like a Hershey’s Kiss, because Bill Nye has a reality check for the alien conspiracy theorists out there.
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.
Question: Hey Bill. So there are many videos online claiming to be extraterrestrial sightings. It just seems that the government is aware of extraterrestrials yet they reject the idea. Possibly they’re hiding the truth from us in fear of the knowledge greatly changing our daily lives. Do you believe these aliens exist and if so would you tell us?
Bill Nye: No I don’t believe the aliens exist coming to visit you and the government knows about it and hasn’t told you. No. Start with that. Two more things. First of all the whole alien thing really got revved up in 1947. There was a project called Sky Hook and the U.S. Government had these very cool super high altitude balloons and they were going to have a constellation of them or an armada of these balloons off the East Coast of the former Soviet Union with microphones tuned to listen for nuclear weapons tests. This was going to be big fun. And so they were testing the balloon in New Mexico and it was complicated and the winds blew the thing around and it crashed and it was impractical. The idea was kind of cool but it was a cold war idea that just didn’t work. Now this project was secret so yes, government people showed up. The U.S. Army swept up all the debris from the crash and took it away because it was secret.
And they also experimented with parachuting dummies from very high altitudes in the same area. And this has led to all these fabulous myths about aliens and the government knows stuff you don’t. Now I look like nobody and I am but I had an engineering job, several of them over the years, and during one of them I had security clearance. And I worked on a secret airplane for a little while and I never went myself but I worked with several guys, they were all men, who went to Area 51 to Groom Lake which is an Air Force base in Nevada where we fly around these secret airplanes. And it’s a real place. And these guys went there and when I was doing it it was called level five security clearance. I only had level four. I never went to Groom Lake. But the big thing they wouldn’t talk about was how fast these planes could go. That was a big secret. But anyway these are people that worked on the F117, a stealth fighter. If you ever go to the Air Force Museum in Ohio you can see the Have Blue secret planes, very cool.
As a kid I always asked myself why don’t they paint spy planes light blue to blend in with the blue sky. Well sometimes they do. Anyway you can see one of those there. So it’s a complete myth that the government knows. Just think how hard it is for the government to keep anything secret. With all due the government kind of sucks at keeping secrets. So they couldn’t possibly keep the secret with 10,000 people in on it. So let’s just set that aside. But with that said you may very well be alive when we discover life or evidence of life rather on Mars. This would literally be alien life. If we find it, if we find some ancient microbes still alive in some icy layer under the Martian sand it would change the world. It would change the way everybody thinks about being a living thing. Do these things on Mars if they exist do they have DNA or did they have DNA if they have been fossilized? Or are they a whole other completely different type of life that we’ve never thought of. Did life start on Mars? Mars got hit with an impactor and you and I are a descendent of Martians? That is amazing. It’s not crazy. It’s extraordinary but it’s not crazy. Then furthermore you may be alive when we send mission to the moon of Jupiter called Europa which has at least twice as much seawater as the earth. When you have seawater for 4.5 billion years is there something alive on Europa? Whoa like dude, that’s out there. It would change the world. It would utterly change the world. This would be real alien life discovered with tax dollars by people who are intellectually curious who decide to devote some of our intellect and treasure to exploring our nearby planetary worlds.
And that’s the real stuff that I encourage you to support and follow. And for that of course I encourage you to join the Planetary Society. Think about that. You don’t have to, I’m just suggesting because we really do advocate for the real exploration of nearby worlds really looking for alien life. Also the James Webb space telescope is going to launch in 2018 and it may have the capability – it is hoped that it will have the capability of exploring atmospheres of extraordinarily distant planets by having sunlight from those stars that those planets orbit pass through the atmospheres. If we detect water vapor and methane it may mean some day that we’ve detected evidence of life on another world. Do, do, do, do – do, do, do, do. It’s all the real stuff is what I’m saying, the real exploration for alien life is more exciting than speculating about a nominally secret Air Force base in Nevada. Carry on.
Peel off your tin-foil hat like a Hershey’s Kiss, because Bill Nye has a reality check for the alien conspiracists out there. Roswell? Area 51? Vincent D'Onofrio as the roach alien in MIB? Bill Nye shoos them away, deeming each as unrealistic as the next.
Nye has some experience when it comes to classified information – not much, he admits, but a little. He once had security clearance while working as an engineer on secret government planes, and although he did not visit Area 51 himself, colleagues with one level higher security clearance than him did go, and what did they find there? Planes. Lots of people, lots of planes, and zero trace of alien life.
The origin of alien conspiracies go back to 1947, when something mysterious fell out of the sky and crashed at a ranch near Roswell, New Mexico. It spurred curiosity and panic; claims emerged that the unknown object was an extraterrestrial spaceship. The government eased people’s minds by revealing that it was nothing but a standard weather balloon that had crashed – and of course, that was a filthy lie. The intrigue was quieted until the late 1970s, when UFO enthusiasts rediscovered the story and images and amped up the interest once again, developing conspiracy theories about alien crash landings. There was no closure until the 1990s, when the US military published reports disclosing what really happened in Roswell: it was an experimental US government spy balloon that had crashed, part of Project Mogul, an attempt to listen out for Soviet murmurs of nuclear testing.
It has been thoroughly investigated and officially debunked, but seeing as the government lied once, the heat on the theory has never really died in the hearts of passionate conspiracy theorists.
But Nye does not believe the government is concealing aliens from us for an even simpler reason: as we can see from the daily political scandals in the media, it is so hard for the government to keep anything a secret.
But he’s not quick to dismiss alien life, and is excited at the prospect of traces being discovered in the next 50 or 100 years, under the icy layers of Mars, or on Jupiter’s intriguing moon Europa. whether that’s a sizeable organism or a mere cell, or fossil.
So there's no reason to narrow your eyes at the government when you ponder alien life. Then again, it’s possible Bill Nye’s body was commandeered by the government using alien technology for the duration of this interview. Or maybe Nye is an alien. And he hangs out with Tupac and Elvis drinking green slime mojitos in a secret ET spa club way out in desert Nevada.

How tiny bioelectronic implants may someday replace pharmaceutical drugs
Scientists are using bioelectronic medicine to treat inflammatory diseases, an approach that capitalizes on the ancient "hardwiring" of the nervous system.

- Bioelectronic medicine is an emerging field that focuses on manipulating the nervous system to treat diseases.
- Clinical studies show that using electronic devices to stimulate the vagus nerve is effective at treating inflammatory diseases like rheumatoid arthritis.
- Although it's not yet approved by the US Food and Drug Administration, vagus nerve stimulation may also prove effective at treating other diseases like cancer, diabetes and depression.
<p>Could a tiny electronic device treat some diseases more safely and effectively than pharmaceutical medicines?</p><p>For Kelly Owens, the answer was clear. She spent more than a decade suffering from Crohn's disease, a chronic inflammatory bowel disease that left her with severe arthritis in her joints. The pain forced her to use a cane, sometimes a wheelchair. She tried more than 20 medications and racked up more than $1 million in medical bills, but her condition didn't improve.</p><p>A physician told Owens and her husband that they shouldn't have children, and that she'd have to take steroids for life.</p><p>Then Owens turned to bioelectronic medicine. She reached out to Dr. Kevin Tracey, a pioneer in the field and president and CEO of the Feinstein Institutes for Medical Research in New York. Soon after, Owens and her husband moved to Amsterdam to participate in a clinical trial involving a relatively new bioelectronic approach to treat inflammation.</p><p>Doctors implanted a small electronic device in her chest that stimulated her vagus nerve, the body's longest cranial nerve. After two weeks, Owens didn't need the cane or wheelchair. Soon she was jogging on a treadmill.</p><p>A growing body of research within bioelectronic medicine shows it's possible to treat diseases by manipulating the nervous system. The field is essentially a fusion of neuroscience, molecular biology and neurotechnology. Dr. Tracey and his colleagues think the field may someday replace or supplement many pharmaceutical drugs used to treat major diseases, including cancer and Alzheimer's.</p><p>But how? The answer centers on how the nervous system controls molecular processes in the body.</p>
<blockquote>...the most revolutionary aspect of bioelectronic medicine, according to Dr. Tracey, is that approaches like vagus nerve stimulation wouldn't come with harmful and potentially deadly side effects, as many pharmaceutical drugs currently do.</blockquote>
The nervous system’s ancient reflexes
<p>You accidentally place your hand on a hot stove. Almost instantaneously, your hand withdraws.</p><p>What triggered your hand to move? The answer is <em>not</em> that you consciously decided the stove was hot and you should move your hand. Rather, it was a reflex: Skin receptors on your hand sent nerve impulses to the spinal cord, which ultimately sent back motor neurons that caused your hand to move away. This all occurred before your "conscious brain" realized what happened.</p><p>Similarly, the nervous system has reflexes that protect individual cells in the body.</p><p>"The nervous system evolved because we need to respond to stimuli in the environment," said Dr. Tracey. "Neural signals don't come from the brain down first. Instead, when something happens in the environment, our peripheral nervous system senses it and sends a signal to the central nervous system, which comprises the brain and spinal cord. And then the nervous system responds to correct the problem."</p><p>So, what if scientists could "hack" into the nervous system, manipulating the electrical activity in the nervous system to control molecular processes and produce desirable outcomes? That's the chief goal of bioelectronic medicine.</p><p>"There are billions of neurons in the body that interact with almost every cell in the body, and at each of those nerve endings, molecular signals control molecular mechanisms that can be defined and mapped, and potentially put under control," Dr. Tracey said in a <a href="https://www.youtube.com/watch?v=AJH9KsMKi5M" target="_blank">TED Talk</a>.</p><p>"Many of these mechanisms are also involved in important diseases, like cancer, Alzheimer's, diabetes, hypertension and shock. It's very plausible that finding neural signals to control those mechanisms will hold promises for devices replacing some of today's medication for those diseases."</p><p>How can scientists hack the nervous system? For years, researchers in the field of bioelectronic medicine have zeroed in on the longest cranial nerve in the body: the vagus nerve.</p><blockquote>What's more, clinical trials show that vagus nerve stimulation not only "shuts off" inflammation, but also triggers the production of cells that promote healing.</blockquote>
The vagus nerve

<p>The vagus nerve ("vagus" meaning "wandering" in Latin) comprises two nerve branches that stretch from the brainstem down to the chest and abdomen, where nerve fibers connect to organs. Electrical signals constantly travel up and down the vagus nerve, facilitating communication between the brain and other parts of the body.</p><p>One aspect of this back-and-forth communication is inflammation. When the immune system detects injury or attack, it automatically triggers an inflammatory response, which helps heal injuries and fend off invaders. But when not deployed properly, inflammation can become excessive, exacerbating the original problem and potentially contributing to diseases.</p><p>In 2002, Dr. Tracey and his colleagues discovered that the nervous system plays a key role in monitoring and modifying inflammation. This occurs through a process called the <a href="https://www.nature.com/articles/nature01321" target="_blank" rel="noopener noreferrer">inflammatory reflex</a>. In simple terms, it works like this: When the nervous system detects inflammatory stimuli, it reflexively (and subconsciously) deploys electrical signals through the vagus nerve that trigger anti-inflammatory molecular processes.</p><p>In rodent experiments, Dr. Tracey and his colleagues observed that electrical signals traveling through the vagus nerve control TNF, a protein that, in excess, causes inflammation. These electrical signals travel through the vagus nerve to the spleen. There, electrical signals are converted to chemical signals, triggering a molecular process that ultimately makes TNF, which exacerbates conditions like rheumatoid arthritis.</p><p>The incredible chain reaction of the inflammatory reflex was observed by Dr. Tracey and his colleagues in greater detail through rodent experiments. When inflammatory stimuli are detected, the nervous system sends electrical signals that travel through the vagus nerve to the spleen. There, the electrical signals are converted to chemical signals, which trigger the spleen to create a white blood cell called a T cell, which then creates a neurotransmitter called acetylcholine. The acetylcholine interacts with macrophages, which are a specific type of white blood cell that creates TNF, a protein that, in excess, causes inflammation. At that point, the acetylcholine triggers the macrophages to stop overproducing TNF – or inflammation.</p><p>Experiments showed that when a specific part of the body is inflamed, specific fibers within the vagus nerve start firing. Dr. Tracey and his colleagues were able to map these relationships. More importantly, they were able to stimulate specific parts of the vagus nerve to "shut off" inflammation.</p><p>What's more, clinical trials show that vagus nerve stimulation not only "shuts off" inflammation, but also triggers the production of cells that promote healing.</p><p>"In animal experiments, we understand how this works," Dr. Tracey said. "And now we have clinical trials showing that the human response is what's predicted by the lab experiments. Many scientific thresholds have been crossed in the clinic and the lab. We're literally at the point of regulatory steps and stages, and then marketing and distribution before this idea takes off."<br></p>The future of bioelectronic medicine
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTYxMDYxMy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzNjQwOTExNH0.uBY1TnEs_kv9Dal7zmA_i9L7T0wnIuf9gGtdRXcNNxo/img.jpg?width=980" id="8b5b2" class="rm-shortcode" data-rm-shortcode-id="c005e615e5f23c2817483862354d2cc4" data-rm-shortcode-name="rebelmouse-image" data-width="2000" data-height="1125" />Vagus nerve stimulation can already treat Crohn's disease and other inflammatory diseases. In the future, it may also be used to treat cancer, diabetes, and depression.

<p>Vagus nerve stimulation is currently awaiting approval by the US Food and Drug Administration, but so far, it's proven safe and effective in clinical trials on humans. Dr. Tracey said vagus nerve stimulation could become a common treatment for a wide range of diseases, including cancer, Alzheimer's, diabetes, hypertension, shock, depression and diabetes.</p><p>"To the extent that inflammation is the problem in the disease, then stopping inflammation or suppressing the inflammation with vagus nerve stimulation or bioelectronic approaches will be beneficial and therapeutic," he said.</p><p>Receiving vagus nerve stimulation would require having an electronic device, about the size of lima bean, surgically implanted in your neck during a 30-minute procedure. A couple of weeks later, you'd visit, say, your rheumatologist, who would activate the device and determine the right dosage. The stimulation would take a few minutes each day, and it'd likely be unnoticeable.</p><p>But the most revolutionary aspect of bioelectronic medicine, according to Dr. Tracey, is that approaches like vagus nerve stimulation wouldn't come with harmful and potentially deadly side effects, as many pharmaceutical drugs currently do.</p><p>"A device on a nerve is not going to have systemic side effects on the body like taking a steroid does," Dr. Tracey said. "It's a powerful concept that, frankly, scientists are quite accepting of—it's actually quite amazing. But the idea of adopting this into practice is going to take another 10 or 20 years, because it's hard for physicians, who've spent their lives writing prescriptions for pills or injections, that a computer chip can replace the drug."</p><p>But patients could also play a role in advancing bioelectronic medicine.</p><p>"There's a huge demand in this patient cohort for something better than they're taking now," Dr. Tracey said. "Patients don't want to take a drug with a black-box warning, costs $100,000 a year and works half the time."</p><p>Michael Dowling, president and CEO of Northwell Health, elaborated:</p><p>"Why would patients pursue a drug regimen when they could opt for a few electronic pulses? Is it possible that treatments like this, pulses through electronic devices, could replace some drugs in the coming years as preferred treatments? Tracey believes it is, and that is perhaps why the pharmaceutical industry closely follows his work."</p><p>Over the long term, bioelectronic approaches are unlikely to completely replace pharmaceutical drugs, but they could replace many, or at least be used as supplemental treatments.</p><p>Dr. Tracey is optimistic about the future of the field.</p><p>"It's going to spawn a huge new industry that will rival the pharmaceutical industry in the next 50 years," he said. "This is no longer just a startup industry. [...] It's going to be very interesting to see the explosive growth that's going to occur."</p>

Physicist creates AI algorithm that may prove reality is a simulation
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.

Surprising Science
- Princeton physicist Hong Qin creates an AI algorithm that can predict planetary orbits.
- The scientist partially based his work on the hypothesis which believes reality is a simulation.
- The algorithm is being adapted to predict behavior of plasma and can be used on other natural phenomena.
<p>A scientist devised a computer algorithm which may lead to transformative discoveries in energy and whose very existence raises the likelihood that our reality could actually be a simulation.</p><p>The algorithm was created by the physicist Hong Qin, from the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL).</p><p>The algorithm employs an AI process called machine learning, which improves its knowledge in an automated way, through experience. </p>
<p><span style="background-color: initial;">Qin developed this algorithm to predict the orbits of planets in the solar system, </span><span style="background-color: initial;">training it on data of </span><span style="background-color: initial;">Mercury, Venus, Earth, Mars, Ceres, and Jupiter orbits</span><span style="background-color: initial;">. The data is "similar to what Kepler inherited from Tycho Brahe in 1601," as Qin writes in his newly-published <a href="https://www.nature.com/articles/s41598-020-76301-0" target="_blank">paper</a> on the subject. From this data, a "serving algorithm" can correctly predict other planetary orbits in the solar system, including parabolic and hyperbolic escaping orbits. What's remarkable, it can do so without having to be told about Newton's laws of motion and universal gravitation. It can figure those laws out for itself from the numbers.</span></p><p>Qin is now adapting the algorithm to predict and even control other behaviors, with a current focus on particles of plasma in facilities built for harvesting fusion energy powering the Sun and stars.</p>

<p>Qin explained the unusual approach taken by his work:</p><p style="margin-left: 20px;">"Usually in physics, you make observations, create a theory based on those observations, and then use that theory to predict new observations, " <a href="https://www.pppl.gov/news/2021/02/new-machine-learning-theory-can-be-applied-fusion-energy-raises-questions-about-very" target="_blank">said Qin.</a> "What I'm doing is replacing this process with a type of black box that can produce accurate predictions without using a traditional theory or law. Essentially, I bypassed all the fundamental ingredients of physics. I go directly from data to data (…) There is no law of physics in the middle."</p><p>Qin was partially inspired by the work of Swedish philosopher Nick Bostrom, whose <a href="https://bigthink.com/mind-brain/are-we-living-in-a-simulation" target="_blank">2003 paper</a> famously argued that the world we are living in may be an artificial simulation. What Qin believes he has accomplished with his algorithm is provide a working example of an underlying technology that could support the simulation in Bostrom's philosophical argument.</p>
<p>In an email exchange with Big Think, Qin remarked: "What is the algorithm running on the laptop of the Universe? If such an algorithm exists, I would argue that it should be a simple one defined on the discrete spacetime lattice. The complexity and richness of the Universe come from the enormous memory size and CPU power of the laptop, but the algorithm itself could be simple."</p><p>Certainly, the existence of an algorithm that derives meaningful predictions of natural events from data does not yet mean that we ourselves have the capabilities to simulate existence. Qin believes we are likely "many generations" away from being able to carry out such feats.</p><p>Qin's work takes the approach of using "discrete field theory," which he thinks is particularly well suited for machine learning, while somewhat difficult for "a current human" to understand. He explained that "a discrete field theory can be viewed as an algorithmic framework with adjustable parameters that can be trained using observational data." He added that "once trained, the discrete field theory becomes an algorithm of nature that computers can run to predict new observations."</p>

This approach was started with Isaac Newton, who invented three approaches to describing continuous spacetime, including Newton's law of motion, Newton's law of gravitation, and calculus.</p><p>Qin believes there are serious issues in modern research that stem from the laws of physics in continuous spacetime being expressed through differential equations and continuous field theories. If laws of physics were based on discrete spacetime, as Qin proposes, "many of the difficulties can be overcome." </p><p>If the world works according to discrete field theory, it would look like something out <em>The Matrix</em>, made of pixels and data points. </p>
<p>Qin's work also coincides with the logic of Bostrom's simulation hypothesis and would mean that "the discrete field theories are more fundamental than our current laws of physics in continuous space."

Fight or flight? Why some people flee and others stand their ground
How different people react to threats of violence.
28 February, 2021

Mind & Brain
Why do some people fight and others flee when confronting violence?
<p> "This question has been bothering me for quite some time," says <a href="https://polisci.mit.edu/people/aidan-milliff" rel="noopener noreferrer" target="_blank">Aidan Milliff</a>, a fifth-year doctoral student who entered political science to explore the strategic choices people make in perilous times.</p><p>"We've learned a great deal how economic status, identity, and pressure from community shape decisions people make while under threat," says Milliff. Early in his studies, he took particular interest in scholarship linking economic deprivation to engagement in conflict.</p><p>"But I became frustrated by this idea, because even among the poorest of the poor, way more people sit out conflict instead of engaging," he says. "I thought there must be something else going on to explain why people decide to take enormous risks."</p><p>A window on this problem suddenly opened for Milliff with class <a href="https://ocw.mit.edu/courses/political-science/17-s950-emotions-and-politics-fall-2018/" rel="noopener noreferrer" target="_blank">17.S950</a> (Emotions and Politics), taught by <a href="https://polisci.mit.edu/people/roger-petersen" rel="noopener noreferrer" target="_blank">Roger Petersen</a>, the Arthur and Ruth Sloan Professor of Political Science. "The course revealed the cognitive processes and emotional experiences that influence how individuals make decisions in the midst of violent conflict," he says. "It was extremely formative in the kinds of research I started to do."</p><p>With this lens, Milliff began investigating questions anew, leveraging unusual data sources and novel qualitative and quantitative methods. His doctoral research is yielding fresh perspectives on how civilians experience threats of violence, and, Milliff believes, "providing policy-relevant insights, explaining how individual action contributes to phenomena like conflict escalation and refugee flows."</p>
<h3>First-person accounts</h3><p>At the heart of Milliff's dissertation project, "Seeking Safety: The Cognitive and Social Foundations of Behavior During Violence," are connected episodes of violence in India: an urban pogrom in Delhi in which nearly 3,000 Sikhs died at the hands of Hindus, sparked by the 1984 assassination of Indira Gandhi by her Sikh bodyguards; and the bloody, decade-long separatist civil war by Sikh extremists in Punjab that began in the 1980s.</p><p>In search of first-person testimony to illuminate people's fight-or-flight choices, Milliff lucked out: He located taped oral histories for a large population of Sikhs who had experienced violence in the 1980s. "In these 500 taped histories, people described at a granular level whether they organized to defend their neighborhoods, hid in houses, left the city temporarily or permanently, or tried to pass as Hindu." He also pursued field interviews in California and India, but didn't get as far as he'd hoped: "I arrived in India last March, and was there for two weeks of an intended three-month stay when I had to return due to the pandemic."</p><p>This setback did not deter Milliff, who managed to convert the oral histories into text and video data that he's already begun to plumb, with the help of natural language processing to code people's decision-making processes. Among his preliminary findings: "People typically appraise their situations in terms of their sense of control and of predictability," he says.</p><p>"When people feel they have a high degree of control but feel that violence is unpredictable, they are more likely to fight back, and when they sense they have neither control nor predictability, and more easily imagine being victims, they flee."<br><br></p>
<h3>A Chicago launchpad</h3><p>Milliff drew inspiration for his doctoral research directly from an earlier graduate project in Chicago with the families of homicide victims.</p><p>"I wanted to learn whether people who become angry in response to violence are more likely to seek retribution," he says. After taping 90 hours of interviews with 31 people, primarily mothers, Milliff shifted his focus. "My initial assumption that everyone would get angry was wrong," he says. "I found that when people suffer these losses, they might get sad instead, or become fearful." In unsolved homicides, family members have no perpetrator to target, but instead turn their anger at government that's let them down, or worry for the safety of surviving family members.</p><p>From this project, Milliff took away a crucial insight: "People respond differently to their tragedies, even when their experiences look similar on paper."</p><p>Political violence and its consequences seized Milliff's interest early on. For his University of Chicago master's thesis, he sought to understand how many long-running, brutal independence movements fizzle out. "I came away from this program believing that I'd enjoy the day-to-day work of being a professional political scientist," he says.</p>
<p>Two research experiences propelled him toward that goal. While in college, Milliff assisted in the National Science Foundation-sponsored General Social Survey, a national social survey headquartered in Chicago, where he learned "how a big quantitative data collection exercise works," he says. Following graduation, a fellowship at the Carnegie Endowment for International Peace immersed him in South Asian military conflict and Indian domestic politics. "I really enjoyed working on these issues and became greatly interested in focusing on the political situation there," he says.</p><p>Attracted by MIT's security studies community, especially its commitment to research with real-world impact, Milliff came to Cambridge, Massachusetts, primed to delve deeper into the subject of political violence. He first had to navigate the graduate program's thorough quantitative sequence. "I came to MIT without having taken math after calculus, and I honestly feel fortunate I ended up somewhere that takes the classroom portion of training seriously," he says. "It has given me new tools I didn't even know existed."</p>
<p>These tools are integral to Milliff's analysis of his singular datasets, and provide the quantitative foundation for informing his policy ideas. If, as his work suggests, people in crisis make decisions based on their sense of control and predictability, perhaps community institutions could bolster citizens' abilities to imagine concrete options. "Lack of predictability and a sense of control encourage people to make choices that are destabilizing, such as fleeing their homes, or joining a fight."</p><p>Milliff continues to analyze data, test hypotheses, and write up his research, taking time out for biking and nature photography. "When I was headed to graduate school, I decided to take up a hobby that I could do for 15 minutes at a time, something I could do between problem sets," he says.</p><p>While he acknowledges research can be taxing, he takes delight in the moments of discovery and validation: "You spend a lot of time coming up with ideas of how the world works, diving into a pit to see if an idea is right," he says. "Sometimes when you surface, you see that you might have come up with a possible new way to describe the world."</p><p>Reprinted with permission of <a target="_blank" href="http://news.mit.edu/">MIT News</a>.

Japan finds a huge cache of scarce rare-earth minerals
Japan looks to replace China as the primary source of critical metals
05 January, 2019

Technology & Innovation
- Enough rare earth minerals have been found off Japan to last centuries
- Rare earths are important materials for green technology, as well as medicine and manufacturing
- Where would we be without all of our rare-earth magnets?
<p>Rare earth elements are a set of 17 metals that are integral to our modern lifestyle and efforts to produce <a href="https://massivesci.com/articles/rare-earth-elements-metals-not-really-that-rare/" target="_blank"><u>ever-greener technologies</u></a>. The "rare" designation is a bit of a misnomer: It's not that they're not plentiful, but rather that they're found in small concentrations, and are especially difficult to successfully extract since they blend in with and resemble other minerals in the ground. China currently produces over 90% of the world's supply of rare metals, with <a href="https://www.mining-technology.com/features/featurescarce-supply-the-worlds-biggest-rare-earth-metal-producers-4298126/" target="_blank"><u>seven other countries</u></a> mining the rest. So though they're not precisely "rare," they <em>are</em> scarce. In 2010, the U.S. Department of energy issued a report that warned of a critical shortage of five of the elements. Now, however, Japan has found a massive deposit of rare earths sufficient to supply the world's needs for hundred of years.</p>
What are the rare earth elements?

<p>The rare earth metals can be mostly found in the second row from the bottom in the Table of Elements. According to the <a href="http://www.rareearthtechalliance.com/What-are-Rare-Earths" target="_blank"><u>Rare Earth Technology Alliance</u></a>, due to the "unique magnetic, luminescent, and electrochemical properties, these elements help make many technologies perform with reduced weight, reduced emissions, and energy consumption; or give them greater efficiency, performance, miniaturization, speed, durability, and thermal stability."</p><p>In order of atomic number, the rare earths are:</p> <ul> <li>Scandium or Sc (21) — This is used in TVs and energy-saving lamps.</li> <li>Yttrium or Y (39) — Yttrium is important in the medical world, used in cancer drugs, rheumatoid arthritis medications, and surgical supplies. It's also used in superconductors and lasers.</li> <li>Lanthanum or La (57) — Lanthanum finds use in camera/telescope lenses, special optical glasses, and infrared absorbing glass.</li> <li>Cerium or Ce (58) — Cerium is found in catalytic converters, and is used for precision glass-polishing. It's also found in alloys, magnets, electrodes, and carbon-arc lighting. </li> <li>Praseodymium or Pr (59) — This is used in magnets and high-strength metals.</li> <li>Neodymium or Nd (60) — Many of the magnets around you have neodymium in them: speakers and headphones, microphones, computer storage, and magnets in your car. It's also found in high-powered industrial and military lasers. The mineral is especially important for green tech. Each <a href="https://www.reuters.com/article/us-mining-toyota/as-hybrid-cars-gobble-rare-metals-shortage-looms-idUSTRE57U02B20090831" target="_blank"><u>Prius</u></a> motor, for example, requires 2.2 lbs of neodymium, and its battery another 22-33 lbs. <a href="https://pubs.usgs.gov/sir/2011/5036/sir2011-5036.pdf" target="_blank"><u>Wind turbine batteries</u></a> require 450 lbs of neodymium per watt. </li> <li>Promethium or Pm (61) — This is used in pacemakers, watches, and research.</li> <li>Samarium or Sm (62) — This mineral is used in magnets in addition to intravenous cancer radiation treatments and nuclear reactor control rods.</li> <li>Europium or Eu (63) — Europium is used in color displays and compact fluorescent light bulbs.</li> <li>Gadolinium or Gd (64) — It's important for nuclear reactor shielding, cancer radiation treatments, as well as x-ray and bone-density diagnostic equipment.</li> <li>Terbium or Tb (65) — Terbium has similar uses to Europium, though it's also soft and thus possesses unique shaping capabilities .</li> <li>Dysprosium or Dy (66) — This is added to other rare-earth magnets to help them work at high temperatures. It's used for computer storage, in nuclear reactors, and in energy-efficient vehicles.</li> <li>Holmium or Ho (67) — Holmium is used in nuclear control rods, microwaves, and magnetic flux concentrators.</li> <li>Erbium or Er (68) — This is used in fiber-optic communication networks and lasers.</li> <li>Thulium or Tm (69) — Thulium is another laser rare earth.</li> <li>Ytterbium or Yb (70) — This mineral is used in cancer treatments, in stainless steel, and in seismic detection devices.</li> <li>Lutetium or Lu (71) — Lutetium can target certain cancers, and is used in petroleum refining and positron emission tomography.</li></ul>Where Japan found is rare earths

<p>Japan located the rare earths about 1,850 kilometers off the shore of <a href="https://en.wikipedia.org/wiki/Minami-Tori-shima" target="_blank"><u>Minamitori Island</u></a>. Engineers located the minerals in 10-meter-deep cores taken from sea floor sediment. Mapping the cores revealed and area of approximately 2,500 square kilometers containing rare earths.</p><p>Japan's engineers estimate there's 16 million tons of rare earths down there. That's <a href="https://minerals.usgs.gov/minerals/pubs/historical-statistics/ds140-raree.xlsx" target="_blank"><u>five times</u></a> the amount of the rare earth elements ever mined since 1900. According to <a href="https://www.businessinsider.com.au/rare-earth-minerals-found-in-japan-2018-4?r=US&IR=T" target="_blank"><u>Business Insider</u></a>, there's "enough yttrium to meet the global demand for 780 years, dysprosium for 730 years, europium for 620 years, and terbium for 420 years."</p><p>The bad news, of course, is that Japan has to figure out how to extract the minerals from 6-12 feet under the seabed four miles beneath the ocean surface — that's the <a href="https://www.nature.com/articles/s41598-018-23948-5" target="_blank"><u>next step</u></a> for the country's engineers. The good news is that the location sits squarely within Japan's Exclusive Economic Zone, so their rights to the lucrative discovery will be undisputed.</p>

Coronavirus
- The gender gap persists, as only 33% of the world's researchers are women.
- Here are just some of the women making lasting contributions in the fight against COVID-19.
- They include Dr Özlem Türeci, co-founder of BioNTech, which helped produce the first vaccine.
<p>Women across the world have made an enormous contribution to the global efforts to tackle COVID-19. Not only do women make up 70% of the world's health workers and first responders, women in STEM fields have been leading research into the virus, creating trackers and developing vaccines.</p><p>But the pandemic has had a <a href="https://www.unwomen.org/en/news/stories/2020/9/feature-covid-19-economic-impacts-on-women" target="_blank">disproportionate social and economic impact on women</a>, as many have borne the brunt of childcare duties or lost jobs in sectors most affected – and this includes <a href="https://www.unwomen.org/en/news/stories/2021/2/statement-ed-phumzile-and-audrey-azoulay-day-of-women-and-girls-in-science" target="_blank">women scientists</a>.</p><p>February 11th is UN International Day of Women and Girls in Science – and the theme this year is celebrating the women scientists at the forefront of the fight against COVID-19, including Dr Özlem Türeci, co-founder of BioNTech, which helped produce the first vaccine.</p>
<p>Women represent almost half the students at Bachelor's (45%), Master's (55%) and PhD (44%) levels of study, according to UNESCO's forthcoming Science Report – but only 33% of the world's researchers are women.</p><p>To encourage more girls and women to take up careers in the STEM fields, UNESCO is gathering some of the world's leading COVID-19 experts for a virtual event.</p><p>"We need science, and science needs women. This is not only about making a commitment to equal rights; it is also about making science more open, diverse and efficient," said Phumzile Mlambo-Ngcuka, Executive Director of UN Women, and Audrey Azoulay, Director-General of UNESCO.</p><p>Here are just some of the women in STEM around the globe who have been making a difference during the pandemic.</p>
