Five collectibles with better returns than the stock market
People often make a killing in stocks, but there are other ways to potentially turn major profits.

- Outside of stocks and bonds, some people make money investing in collectibles and make a fair amount on them.
- One stamp even sold for a billion times its face value.
- The extreme dependence on future collectability, however, limits the potential of most of these opportunities.
The question of how to make your money work for you is a never-ending problem. While stocks, bonds, and currencies of all kinds are common choices, they aren't the only things you can put your money into. Various collectibles, household objects, and clothing articles have made headlines for being sources of income for people who can predict which ones will end up being valuable years after purchase and reaping the profits.
While the word "investment" is a strong one, some people really do buy these items in hopes of reselling them for higher amounts later, much as you might do with stocks or bonds. So, let's look at five alternative investing options with occasionally eye-popping returns.
Pokémon Cards
For those who weren't content to catch them all in a video game came a trading card game where you could collect them all. Some classic cards have gained tremendous stature among collectors and Pokéfanatics and sell for extremely high prices.
An older card featuring Charizard, a fire breathing dragon, regularly sells for thousands online. Given that the card could be purchased for a couple dollars in 1999, this is quite the return. A particular pack of Pokémon cards, which cost $5 in 2003, now sells for $650, 130 times the original asking price.
Of course, not every card will fetch these high prices. Buying cards as an investment is tricky. You have to essentially guess at which cards will be considered highly valuable at a later date and will be unable to collect dividends before selling them.
Furthermore, you have to presume that people will be collecting the cards years after buying them. While Pokémon has remained popular, it is a bit of an outlier in terms of enduring success.
Sneakers

People from all walks of life—from skateboarders to the First Lady of the Philippines—enjoy collecting shoes. An entire subculture exists for people interested in collecting sneakers, and some people make quite a profit in it.
The Nike SB Dunk Low Reese Forbes Denims, priced initially at $65 in 2002, are commonly valued in the thousands of dollars now. The Nike Air Jordan 1 Retro High x Off White "Chicago" shoe sold for $190 a mere four years ago, but now sells for $4000 a pair.
A Huffington Post article points out that most of these shoes offered better returns than gold over the same period. The same article quotes YouTube personality Mr. Foamer Simpson and his explanation of the difficulties of making money on shoes:
"There's a guessing game or element of unpredictability that makes it exciting for some collectors. With sneakers, you kind of never know. Sure, you know what sneakers are more limited or which ones were harder to get, but even with that, it fluctuates a lot. A sneaker that was very valuable two years ago might all of a sudden crash and no longer be valuable."
Toys of all kinds
If there's one thing everybody loves, it's what they loved when they were children. That often translates into old and rare toys fetching insane prices at auction.
Beanie Babies, those little stuffed animals from the 1990s, once sold for thousands of dollars online, not bad considering they originally cost $5. LEGO sets, particularly those featuring well-known franchises like Star Wars, can sell for hundreds online.
As with Pokémon cards, the success stories are dependent on what people are interested in collecting long after most people forgot the toy existed. While some collectors have ideas on how to gauge what might or might not end up being valuable later, there seems to be a considerable amount of luck involved.
Stamps
The hobby of kings has occasionally made some people as rich as one, with rare stamps and extensive collections fetching high prices at auction.
One of the famous "Inverted Jenny" stamps, a rare misprint showing an upside-down airplane, sold for $1,593,000 at auction. The most valuable stamp in the world, the British Guiana 1c magenta, last sold for $9,480,000, a billion times its face value. For those interested in a shorter-term investment, the USA Forever stamp has gained a face value of 75% since its introduction and can still be used to send a letter.
Coins
For those who want to invest in actual money but without having it do money-related things, collectible coins may be the ticket.
The misprinted Wisconsin State Quarter, featuring an extra leaf on an ear of corn, can sell for up to $2,800, though the price has declined in recent years. Older coins made of precious metals are also highly valued; a silver dollar from 1804 sold for nearly $2,000,000 at auction. Even old wheat pennies can sell for a couple of dollars today.
While these collectibles can provide high returns on your investment in them, they don't provide dividends, and their value is entirely dependent on how much collectors are willing to pay for the particular item you have. As a couple of the above examples show, tastes can change and leave your investment worthless. If you have some luck, an eye for trends, and the good fortune not to have thrown out your old stuff, you might be able to make a fair amount on it.
Of course, if you manage to get rich because you found an old coin in your desk after reading this article, be sure to remember who wrote it.
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.
Left: The vagus nerve, the body's longest cranial nerve. Right: Vagus nerve stimulation implant by SetPoint Medical.
- 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.
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>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>Just how cold was the Ice Age? New study finds the temperature
Researchers figure out the average temperatures of the last ice age on Earth.

Best. Science. Fiction. Show. Ever.
"The Expanse" is the best vision I've ever seen of a space-faring future that may be just a few generations away.
- Want three reasons why that headline is justified? Characters and acting, universe building, and science.
- For those who don't know, "The Expanse" is a series that's run on SyFy and Amazon Prime set about 200 years in the future in a mostly settled solar system with three waring factions: Earth, Mars, and Belters.
- No other show I know of manages to use real science so adeptly in the service of its story and its grand universe building.

<p>Now, I get it if you don't agree with me. I love "Star Trek" and I thought "Battlestar Galactica" (the new one) was amazing and I do adore "The Mandalorian". They are all fun and important and worth watching and thinking about. And maybe you love them more than anything else. But when you sum up the acting, the universe building, and the use of real science where it matters, I think nothing can beat "The Expanse". And with a <a href="https://www.rottentomatoes.com/tv/the_expanse" target="_blank">Rotten Tomato</a> average rating of 93%, I'm clearly not the only one who feels this way.</p><p>Best.</p><p>Show.</p><p>Ever. </p>How exercise changes your brain biology and protects your mental health
Contrary to what some might think, the brain is a very plastic organ.
As with many other physicians, recommending physical activity to patients was just a doctor chore for me – until a few years ago. That was because I myself was not very active.
Here's a 10-step plan to save our oceans
By 2050, there may be more plastic than fish in the sea.
