- The Gateway Foundation is building a space hotel, based on the concepts of a Nazi and American rocket scientist Wernher von Braun.
- The space station is expected to be operational by 2025.
- The company plans to assemble it in orbit, using robots and drones.
If Earthly destinations are not enough to quench your wanderlust, a trip to a space hotel might get on your radar within the next few years. The designer of the Von Braun Space Station revealed numerous plans that detail the construction of a veritable resort in space.
Built by the Gateway Foundation, the world's first space hotel will have gravity, bars, inviting interiors and full-fledged kitchens. They plan to have the station visited by about a 100 tourists per week by 2025.
The designer of the project, Tim Alatorre, wants to make traveling to space commonplace.
"Eventually, going to space will just be another option people will pick for their vacation, just like going on a cruise, or going to Disney World," Alatorre revealed in an interview with Dezeen.

He thinks that while initially space travel will be the domain of the uber-wealthy, soon enough it will be available to regular folks.
The Space Station will utilize existing tech used at the International Space Station, but will differ in one crucial aspect – the hotel will have artificial gravity, making long-term stay much more manageable. The designer thinks gravity, about a sixth of Earth's, will add a "sense of direction and orientation that isn't present in the ISS." You'd also be able to go to a toilet, shower or eat food the way you are used to.

The ideas for the station were taken from none other than Wernher von Braun – hence its name. If you recall, Wernher von Braun was a top Nazi rocket scientist who developed the infamous V2 rocket. After the war, he was taken in by NASA and became a famous American scientist. The hotel will be a part of his complex legacy.
The station will be made of a giant wheel, 190 meters in diameter, which will be rotating to generate a gravitational force (similar in pull to the moon's). 24 individual modules with sleeping and support facilities will be spread around the wheel on three decks, providing accommodations to about 400 people in total.
Alatorre compares the hotel to a cruise ship, pointing out it will have "many of the things you see on cruise ships: restaurants, bars, musical concerts, movie screenings, and educational seminars." Just in space.

"The dream of the Gateway Foundation is to create starship culture, where there is a permanent community of space-faring people living and working in Earth's orbit and beyond," shared Alatorre.

Some of the modules could be sold like condos. Others will be available for scientific research to governments and the like.
The designer explained that the interiors of the hotel will be created using modern natural materials that would substitute for stone and wood and be lightweight and easy to clean. The warm-colored lighting, paints and textures will add to a homey feel.
If you're wondering what you can do for fun in such an environment, the designers are planing to provide such activities as low-gravity basketball, trampolining and rock climbing. You can also play something akin to Quidditch from Harry Potter and new games that would have to be figured out to take advantage of the fresh possibilities.
How will the station be built? By using automated systems like drones and robots, while in orbit. It will also make use of GSAL, special space construction machinery developed by Orbital Construction.
Looking ahead, the Gateway Foundation sees the Von Braun Space Station as their proof of concept. They intend to build bigger space stations as demand for such vacations grows. Their next class of station is called The Gateway and can accommodate more than 1,400 people.

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

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>

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
Rare-earth magnets (nikkytok/Shutterstock)
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?

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.

Is it time to decriminalize prostitution? Two New York bills answer yes in unique ways
One bill hopes to repeal the crime of selling sex and expand social services; the other would legalize the entire sex trade.

<ul class="ee-ul"></ul>
<p>Although incorrectly labeled <a href="https://slate.com/news-and-politics/2012/03/rush-limbaugh-calls-sandra-fluke-a-prostitute-is-prostitution-really-the-worlds-oldest-profession.html" target="_blank">the world's oldest profession</a>, prostitution has been on the minds of lawmakers for as long as extant laws allow us to track. The Code of Hammurabi, the most complete of ancient Babylonian laws, doesn't deal with the sex trade directly but does distinguish between the inheritance rights enjoyed by "devoted women" versus prostituted women.</p><p>A few centuries later and across the Mediterranean, the ancient Greek and Roman civilizations regulated a legal sex trade depicted on frescos and black-and-red-figure vases in exotic and highly idealized terms. However, the courtesan's life was hardly a high-minded exercise in sexual liberation. Freeborn wives and daughters did not participate in the sex trade. Instead, these societies filled their brothels with slaves and <a href="https://en.wikipedia.org/wiki/Infamia" target="_blank"><em>infames</em></a> and allowed them to suffer in abhorrent living conditions. The <a href="https://theconversation.com/the-grim-reality-of-the-brothels-of-pompeii-88853" target="_blank" rel="noopener noreferrer">ashen evidence</a> from <a href="https://bigthink.com/culture-religion/mount-vesuvius-eruption" target="_self">Pompeii</a> reveals that prostituted women and young men were immured within dark, stifling cells barely large enough to house their stone beds.</p><p>In the United States today prostitution is entirely illegal, save for a few counties in the state of Nevada. Yet, <a href="https://www.bjs.gov/content/pub/pdf/fphtc15.pdf" target="_blank" rel="noopener noreferrer">trafficking persists across the country</a>. <a href="https://fieldcenteratpenn.org/wp-content/uploads/2013/05/6230-R10-Field-Center-Full-Report-Web.pdf" target="_blank" rel="noopener noreferrer">One study from the Field Center for Children's Policy</a>, University of Pennsylvania, interviewed vulnerable youths across 13 cities and found that roughly a fifth were victims of sex trafficking. Many said they were approached for paid sexual acts during their first night of homelessness.</p><p>Opponents of the full-criminalization model argue that these regulations only aggravate such problems, driving prostituted people further underground, where harm and violence may be inflicted upon them without recourse. In recent decades, European countries have introduced new prostitution laws, leading U.S. advocates to raise their voices for decriminalization. And two new bills introduced in the New York State Senate hope to make that change.</p>
The Equality Model asks, criminal or victim?

<p>The most recent of the two is the Sex Trade Survivors Justice & Equality Act. Set to be introduced by Senator Liz Krueger of Manhattan, the law would repeal the crime of prostitution in the state but would maintain punitive measures against buyers and pimps. The penalty for buying sex, for example, would be a sliding-scale fine based on income.<strong> </strong>The bill also aims to strengthen laws against trafficking and eliminate the so-called <a href="http://ypdcrime.com/penal.law/article230.htm#p230.03" target="_blank">ignorance defense</a>, which affords buyers legal cover if they did not have "reasonable grounds" to assume their victim was underage.</p><p>The Sex Trade Survivors Justice & Equality Act is based on <a href="https://www.equalitymodelus.org/why-the-equality-model/" target="_blank">the Equality Model</a>, first introduced in Sweden in 1999. Under the Swedish Sex Purchase Act, the country decriminalized prostitution and began targeting buyers and suppliers with the goal of lowering demand. As demand decreased, the thinking went, Sweden would witness a subsequent reduction in violence, trafficking, and the trauma associated so strongly with the illicit sex trade. And <a href="https://www.government.se/4a4908/contentassets/8f0c2ccaa84e455f8bd2b7e9c557ff3e/english-summary-of-sou-2010-49.pdf" target="_blank" rel="noopener noreferrer">a 2008 report</a> did find that the strategy manifested some of those goals. </p><p>After the law's introduction, costs increased, fewer men sought to purchase sex, and the number of women in street prostitution halved—though the burgeoning internet scene likely influenced that metric as much as the law. </p><p>As for Sweden's prostituted population, the report was mixed. Fears of the law driving prostitution further underground weren't realized, nor did the risks of physical abuse or dangerous living conditions increase. However, while people who sought to leave the life favored the law, those who wished to stay in the trade denigrated it for hyping the social stigma. </p><p>After the report's release, countries such as Norway, Iceland, Canada, and Israel adopted the Equality Model, and today, many U.S. advocacy groups champion for states to institute similar laws.</p><p>"We who have been in the human-trafficking policy movement for a long time have been advocating for years that people in prostitution should not be criminalized for their exploitation," Alexi Meyers, director of anti-trafficking policy at <a href="https://sanctuaryforfamilies.org/" target="_blank" rel="noopener noreferrer">Sanctuary for Families</a>, told Big Think in an interview discussing the New York bill. "It's the only law where the victim is arrested. Instead of handcuffs, [people in prostitution] need services, need housing, need support."</p><p>Critically, the Sex Trade Survivors Justice & Equality Act does more than decriminalize prostitution. It also bolsters social services such as housing, job training, and mental health care. To help finance these services, money collected by the aforementioned buyer fine will go into a victim-compensation fund. The bill also expands protections for minors arrested under safe harbor and would vacate victims' prior convictions so they could more easily find jobs. </p><p>"When someone has had no family support, have been abused their entire lives, and they haven't gotten the services they need, at the age of 18, they haven't magically transformed from a victim of trafficking into a prostitute," Jayne Bigelsen, vice president of advocacy for Covenant House, New York, said in our interview.</p><p>Bigelsen grants that not everyone engaged in the commercial sex trade may view themselves as a victim, but she notes that a large portion of the population remains vulnerable nonetheless. To treat such people as criminals, as so many contemporary laws do, does no one any favors. The fear of arrest <a href="http://www.prostitutionresearch.com/pdf/Prostitutionin9Countries.pdf" target="_blank" rel="noopener noreferrer">actively discourages</a> victims from seeking an "off-ramp" to the life and strengthens the coercive hold their pimps and traffickers maintain on them.</p><p>"[The law helps] reframe the understanding that this is not a crime. It is a form of gender-based violence and exploitation. I think, over time, people will have a greater understanding of that," Bigelsen adds.</p>Prostitution, an occupation like any other?

<p>But critics of the Equality Model believe it's disguised paternalism that robs women of the right to choose. Worse, they argue, it further stigmatizes sex workers within society and drives the sex trade further underground, where exploitation and violence can continue to fester from prying eyes.</p><p><a href="https://www.nysenate.gov/legislation/bills/2019/s6419#:~:text=S6419%20(ACTIVE)%20%2D%20Sponsor%20Memo&text=Part%20B%20repeals%20and%20amends,are%20repealed%20under%20this%20bill." target="_blank">A second New York Senate bill</a>, currently in committee, would decriminalize the entire sex trade within the state. Called the Stop Violence in the Sex Trades Act, the bill would keep penal laws related to minors and sex trafficking but would make sex work between consenting adults a legal, regulated trade.</p><p>"Sex work is work and should not be criminalized by the state," Senator Julia Salazar, who introduced the bill, stated in <a href="https://www.decrimny.org/post/for-immediate-release-decrim-ny-legislators-intro-first-statewide-bill-to-decriminalize-sex-work" target="_blank" rel="noopener noreferrer">a press release</a>. "Our current policies only empower traffickers and others who benefit from keeping sex work in the shadows. New York State needs to listen to sex workers and make these common-sense reforms to keep sex workers safe and empower sex workers in their workplaces."</p><p>Like the Sex Trade Survivors Justice & Equality Act, Salazar's bill draws inspiration from European laws, namely those from the Netherlands and Germany. Both countries legalized the sex trade a few years after Sweden introduced its Equality Model—though laws and regulations vary between the countries and even districts within them. For example, <a href="https://www.dw.com/en/germany-introduces-unpopular-prostitution-law/a-39511761" target="_blank" rel="noopener noreferrer">Germany has passed a law</a> that requires any business offering sex services to apply for a permit "that will only be granted if health, hygiene and room requirements are met," while <a href="https://www.amsterdam.nl/en/policy/policy-health-care/policy-prostitution/#:~:text=In%20Amsterdam%2C%20prostitution%20in%20private,supplying%20locations%20for%20illegal%20prostitution." target="_blank" rel="noopener noreferrer">Amsterdam limits</a> window prostitution to specific city zones.</p><p>Full-decriminalization advocates hope such laws will facilitate freedom of choice, access to social services, improved health and working conditions, and the decoupling of the occupation from criminal enterprises. They also argue that full decriminalization closes the unintended consequences created by the Equality Model.</p><p>An <a href="https://www.amnesty.org/en/latest/news/2016/05/amnesty-international-publishes-policy-and-research-on-protection-of-sex-workers-rights/" target="_blank" rel="noopener noreferrer">Amnesty International</a> report notes that in Norway, sex workers are routinely evicted from their homes because landlords fear rental agreements will expose them to prosecution for promoting sex. Similar liability concerns deter third parties, such as security, from working with sex workers, too. As a result, sex workers themselves may not be prosecuted but their lives are no less secure nor more firmly established within society.</p><p>"What we have isn't working. The current model of criminalizing sex work traps sex workers and trafficking survivors in cycles of violence. The new proposed legislation referred to as the 'Equality Model' conflates sex work with sex trafficking, using the logic of broken windows policing to address trafficking by targeting sex workers," <a href="https://www.decrimny.org/post/the-equality-model-is-criminalization-by-another-name-pass-the-stop-violence-in-the-sex-trades-act" target="_blank" rel="noopener noreferrer">writes the advocacy group Decrim NY</a>.</p>New York State to lead decriminalization

Even in countries that have legalized prostitution, the sex trade retains <a href="https://www.bbc.com/news/world-europe-46919294" target="_blank">strong ties to criminal activities</a>. Prostituted women continue to be viewed as pariah—or, in the case of Amsterdam, tourist attractions. And like the legal sex trades of the ancient world, contemporary examples have witnessed a surge in human trafficking to meet the demand. More often than not, poor women from poor countries.</p><p>"If you decriminalize people who buy sex, you're removing any legal barriers or social barriers, and the number of people who buy sex will exponentially increase, and you'll have to fill that new, legal demand with supply. And that supply is human bodies, and there aren't enough willing participants to fulfill that need. That's when trafficking occurs," Alexi Myers said.</p><p><a href="https://ec.europa.eu/anti-trafficking/sites/antitrafficking/files/federal_government_report_of_the_impact_of_the_act_regulating_the_legal_situation_of_prostitutes_2007_en_1.pdf" target="_blank">A report commissioned</a> by Germany's Federal Ministry for Family Affairs, Senior Citizens, Women and Youth looked into the effects of the country's 2001 law. It found the intended impacts to be lacking. According to the report, the Prostitution Act did not create measurable improvements on social protection, working conditions, reduced crime, or the means for leaving the business. The report did assuage some fears, however, by finding that legalization did not make it more difficult to prosecute sex traffickers or related violence when they occurred.</p><p>All told, data will never point to a perfect solution to this or any social concern. In the case of prostitution, emotions and moral instinct run at the redline. Often, the solution one proposes comes down to one's answer of this question: What is prostitution? Is it a violation of another human's rights and dignity? An occupation like any other? Or a moral offense old as the law itself? </p><p>Whatever your answer, you'll likely find current U.S. law lacking. It's for this reason that <a href="https://www.governing.com/archive/more-states-separate-prostitution-sex-trafficking.html" target="_blank" rel="noopener noreferrer">many states are reanalyzing and revamping their prostitution laws</a> to protect victims, usually with more robust safe harbor laws. Whichever law New York State chooses, its successes and failures will likely serve as a bellwether for the United States moving forward.</p>

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 "The Matrix," 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." In fact, writes Qin, "our offspring must find the discrete field theories more natural than the laws in continuous space used by their ancestors during the 17<span style="background-color: initial;"><sup>th</sup></span>-21<span style="background-color: initial;"><sup>st</sup></span> centuries."</p><p>Check out Hong Qin's paper on the subject in <a href="https://www.nature.com/articles/s41598-020-76301-0" target="_blank">Scientific Reports.</a></p>
