Now there’s one more thing that parents can give their children to ensure their future success in life – a digital trust fund. Yep, that’s right, it's no longer enough for well-to-do parents to set up financial trust funds for their kids and hand off personal fortunes at the age of 18, they now must consider creating digital trust funds and handing off pre-packaged digital legacies to children as young as three. While social networking sites like Facebook restrict parents from etablishing personal profiles for children under the age of 13, they are gradually yielding to parents who want their children to have an online presence earlier than that with features like "Facebook for unborn children." These digital trust fund kids will be the true digital natives – kids who have a digital footprint by the time they’re old enough to talk and are ready to tweet by the time they're in kindergarten.
It used to be that the first years of a child’s life were a blank slate. Maybe an embarrassing photo or two, a few family scrapbooks with sentimental mementos, but certainly nothing that could be shared by thousands of people online in a digital format. Think about it – what’s the first memory you have of your own life? Most likely, it came around age five, which is when psychologists and baby philosophers say most of us start creating permanent memories. To get around this "memory problem," parents are embracing the implied permanance of the Internet: they are creating Facebook accounts, claiming passwords and usernames on other social sites, and creating a digital identity for their children even before they’re born. They are fake-tweeting for babies the same way PR flacks fake-tweet for celebrities. They are relentlessly over-sharing every moment of their babies' lives, to the point where it has even become an Internet meme, STFU, Parents.
Not only that, but they are embracing mobile apps that allow them to track every step of a baby's life. This obsession surely has its roots in the helicopter style of parenting so in vogue these days. Beyond just taking an interest in every aspect of a child’s development, parents are actually intruding into personal areas that have no precedent. Some even call it "hijacking" a child's identity. Imagine a child using Twitter for the first time and realizing that - surprise! - you've been sending ridiculous 140-character tweets for years. Parents have always wanted their memories to intertwine with the memories of their children - now they have a way to do this with off-the-shelf digital tools.
By creating a digital trust fund that contains all the building blocks of a digital identity, parents are theoretically girding their children for success in a digital world. During the first Internet boom, parents took steps like reserving personal domain names for their children. Now, with the social networking boom, they have a mind-boggling number of social sites to keep in mind. Should they start signing up for Twitter and Pinterest accounts - or is it simply too creepy to assume a child's identity before he or she's even had a chance to say anything in the matter (literally)?
A digital trust fund comprises more than just a URL held in perpetuity and profiles across all the major social networking sites. It also means that parents should establish a baseline of historical reference, as in Google Chrome's "Dear Sophie" ad:
"Lots of parents think it’s cool to buy a domain name for their kid, but few will make the time to explain to their kids how technology has evolved over time. Explaining this evolution will give your child a deeper perspective from which to operate their business or brand going forward. Drop a Gmail message to your kid in their new account from time to time, upload a YouTube video and write down your thoughts on the state of the Twitter/Facebook/Foursquare-sphere so they have a better understanding of the limits and breakthroughs made by technology each year."
Of course, as with anything related to digital data and social networking, there’s rampant debate about what exactly parents are doing to their children by creating “digital trust funds.” Should parents really be breathlessly documenting every moment of their young ones' lives via photos and videos and Facebook status updates? In the Wall Street Journal, for example, there was discussion on the relative merits of creating a “Facebook-free baby." Just as there are adults who pledge to stay away from Facebook, there are parents who pledge to keep their kids away from The Social Network.
But what if having a digital trust fund turns out to be just as desirable as having a financial trust fund? At the end of the day, we are surely headed to digital Day Zero – the point when our digital legacies and digital identities start at the day of birth, not at some arbitrary point in childhood - like age 13 - when we think “our kids can handle it.” In places like Sweden, nearly one-half of all toddlers age 3 are already using the Internet. In New York City's TriBeCa, kindergartners are getting crash courses in Twitter. Speeding up the point of digital entry for the average toddler may turn out to be a fabulously misguided experiment driven as much by parental ego as by some altruistic concern about the future -- but can we really afford not to give our children every advantage in life if the opportunity already exists today?

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.
Icebergs.
- A new study analyzes fossil data to find the average temperatures during the last Ice Age.
- This period of time, about 20,000 years ago, had the average temperature of about 46 degrees Fahrenheit (7.8 C).
- The study has implications for understanding climate change.

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.
