The Future of Nanotechnology in Medicine

Around the world, researchers are increasingly thinking smaller to solve some of the biggest problems in medicine.

Though most biological processes happen at the nano level, it wasn’t until recently that new technological advancements helped in opening up the possibility of nanomedicine to healthcare researchers and professionals.

Today’s infographic, which comes to us from Best Health Degrees, highlights some of the most promising research in nanomedicine.

What is Nanotechnology?

Nanotechnology is the engineering of functional systems at the molecular level. The field combines elements of physics and molecular chemistry with engineering to take advantage of unique properties that occur at nanoscale.

One practical example of this technology is the use of tiny carbon nanotubes to transport drugs to specific cells. Not only do these nanotubes have low toxicity and a stable structure, they’re an ideal container for transporting drugs directly to the desired cells.

Small Systems, Big Applications

While many people will be most familiar with nanotech as the technology powering Iron Man’s suit, real world breakthroughs at the nanoscale will soon be saving lives in healthcare.

Here are a few ways nanotechnology is shaping the future of medical treatment:

1. Smart Pills

While smart pill technology is not a new idea — a “pill cam” was cleared by the FDA in 2001 — researchers are coming up with innovative new applications for the concept.

For example, MIT researchers designed an ingestible sensor pill that can be wirelessly controlled. The pill would be a “closed-loop monitoring and treatment” solution, adjusting the dosage of a particular drug based on data gathered within the body (e.g. gastrointestinal system).

An example of this technology in action is the recent FDA-approved smart pill that records when medication was taken. The product, which is approved for people living with schizophrenia and bipolar disorder, allows patients to track their own medication history through a smartphone, or to authorize physicians and caregivers to access that information online.

2. Beating the Big C

Nearly 40% of humans will be diagnosed with cancer at some point in their lifetime, so any breakthrough in cancer treatment will have a widespread impact on society.

On the key issues with conventional chemotherapy and radiation treatments is that the body’s healthy cells can become collateral damage during the process. For this reason, researchers around the world are working on using nano particles to specifically target cancer cells.

Oncology-related drugs have the highest forecasted worldwide prescription drug sales, and targeting will be a key element in the effectiveness of these powerful new drugs.

3. Diagnostics

Medical implants — such as knee and hip replacements — have improved the lives of millions, but a common problem with these implants is the risk of post-surgery inflammation and infection. In many cases, symptoms from an infection are detected so late that treatment is less effective, or the implant will need to be replaced all together.

Nanoscale sensors embedded directly into the implant or surrounding area could detect infection much sooner. As targeted drug delivery becomes more feasible, it could be possible to administer treatment to an infected area at the first sign of infection.

Examples like this show the true promise of nanotechnology in the field of medicine. Before long, gathering data from within the body and administering treatments in real-time could move from science fiction to the real world.

10,000 years ago, man domesticated plants and animals, now it’s time to domesticate molecules.

Big Tech CEO Insider Trading During The First Half of 2021

When CEOs of major companies are selling their shares, investors can’t help but notice.

After all, these decisions have a direct effect on the personal wealth of these insiders, which can say plenty about their convictions with respect to the future direction of the companies they run.

Considering that Big Tech stocks are some of the most popular holdings in today’s portfolios, and are backed by a collective $5.3 trillion in institutional investment, how do the CEOs of these organizations rank by their insider selling?

CEOStockShares Sold H1 2021Value of Shares ($M)
Jeff BezosAmazon (AMZN)2.0 million$6,600
Mark ZuckerbergFacebook (FB)7.1 million$2,200
Satya NadellaMicrosoft (MSFT)278,694
$65
Sundar PichaiGoogle (GOOGL)27,000$62
Tim CookApple (AAPL)0$0

Breaking Down Insider Trading, by CEO

Let’s dive into the insider trading activity of each Big Tech CEO:

Jeff Bezos

During the first half of 2021, Jeff Bezos sold 2 million shares of Amazon worth $6.6 billion.

This activity was spread across 15 different transactions, representing an average of $440 million per transaction. Altogether, this ranks him first by CEO insider selling, by total dollar proceeds. Bezos’s time as CEO of Amazon came to an end shortly after the half way mark for the year.

Mark Zuckerberg

In second place is Mark Zuckerberg, who has been significantly busier selling than the rest.

In the first half of 2021, he unloaded 7.1 million shares of Facebook onto the open market, worth $2.2 billion. What makes these transactions interesting is the sheer quantity of them, as he sold on 136 out of 180 days. On average, that’s $12 million worth of stock sold every day.

Zuckerberg’s record year of selling in 2018 resulted in over $5 billion worth of stock sold, but over 90% of his net worth still remains in the company.

Satya Nadella

Next is Satya Nadella, who sold 278,694 shares of Microsoft, worth $234 million. Despite this, the Microsoft CEO still holds an estimated 1.6 million shares, which is the largest of any insider.

Microsoft’s stock has been on a tear for a number of years now, and belongs to an elite trillion dollar club, which consists of only six public companies.

Sundar Pichai

Fourth on the list is Sundar Pichai who has been at the helm at Google for six years now. Since the start of 2021, he’s sold 27,000 shares through nine separate transactions, worth $62.5 million. However, Pichai still has an estimated 6,407 Class A and 114,861 Class C shares.

Google is closing in on a $2 trillion valuation and is the best performing Big Tech stock, with shares rising 60% year-to-date. Their market share growth from U.S. ad revenues is a large contributing factor.

Tim Cook

Last, is Tim Cook, who just surpassed a decade as Apple CEO.

During this time, shares have rallied over 1,000% and annual sales have gone from $100 billion to $347 billion. That said, Cook has sold 0 shares of Apple during the first half of 2021. That doesn’t mean he hasn’t sold shares elsewhere, though. Cook also sits on the board of directors for Nike, and has sold $6.9 million worth of shares this year.

Measuring Insider Selling

All things equal, it’s desirable for management to have skin in the game, and be invested alongside shareholders. It can also be seen as aligning long-term interests.

A good measure of insider selling activity is in relation to the existing stake in the company. For example, selling $6.6 billion worth of shares may sound like a lot, but when there are 51.7 million Amazon shares remaining for Jeff Bezos, it actually represents a small portion and is probably not cause for panic.

If, however, executives are disclosing large transactions relative to their total stakes, it might be worth digging deeper.

The World’s Most Used Apps, by Downstream Traffic

Of the millions of apps available around the world, just a small handful of the most used apps dominate global internet traffic.

The World’s Most Used Apps by Downstream Traffic Share

The World’s Most Used Apps, by Downstream Traffic

Of the millions of apps available around the world, just a small handful of the most used apps dominate global internet traffic.

Everything connected to the internet takes bandwidth to view. When you look at something on your smartphone—whether it’s a new message on Instagram or the next few seconds of a YouTube video—your device is downloading the data in the background.

And the bigger the files, the more bandwidth is utilized. In this chart, we break down of the most used apps by category, using Sandvine’s global mobile traffic report for 2021 Q1.

Video Drives Global Mobile Internet Traffic

The biggest files use the most data, and video files take the cake.

According to Android Central, streaming video ranges from about 0.7GB per hour of data for a 480p video to 1.5GB per hour for 1080. A 4K stream, the highest resolution currently offered by most providers, uses around 7.2GB per hour.

That’s miles bigger than audio files, where high quality 320kbps music streams use an average of just 0.12GB per hour. Social network messages are usually just a few KB, while the pictures found on them can range from a few hundred KB for a low resolution image to hundreds of MB for high resolution.

Understandably, breaking down mobile downstream traffic by app category shows that video is on top by a long shot:

CategoryDownstream Traffic Share (2021 Q1)
Video Streaming48.9%
Social Networking19.3%
Web13.1%
Messaging6.7%
Gaming4.3%
Marketplace4.1%
File Sharing1.3%
Cloud1.1%
VPN and Security0.9%
Audio0.2%

Video streaming accounts for almost half of mobile downstream traffic worldwide at 49%. Audio streaming, including music and podcasts, accounts for just 0.2%.

Comparatively, social network and web browsing combined make up one third of downstream internet traffic. Games, marketplace apps, and file sharing, despite their large file sizes, only require one-time downloads that don’t put as big of a strain on traffic as video does.

A Handful of Companies Own the Most Used Apps

Though internet traffic data is broken down by category, it’s worth noting that many apps consume multiple types of bandwidth.

For example, messaging and social network apps, like WhatsApp, Instagram, and Snapchat, allow consumers to stream video, social network, and message.

Even marketplace apps like iTunes and Google Play consume bandwidth for video and audio streaming, and together account for 6.3% of total mobile downstream traffic.

But no single app had a bigger footprint than YouTube, which accounts for 20.4% of total global downstream bandwidth.

CategoryTop Apps (Category Traffic)Category Traffic Share
Video StreamingYouTube47.9%
Video StreamingTikTok16.1%
Video StreamingFacebook Video14.6%
Video StreamingInstagram12.1%
Video StreamingNetflix4.3%
Video StreamingOther5.0%
Social NetworkingFacebook50.5%
Social NetworkingInstagram41.9%
Social NetworkingTwitter2.4%
Social NetworkingOdnoklassniki1.9%
Social NetworkingQQ0.7%
Social NetworkingOther2.9%
MessagingWhatsApp31.4%
MessagingSnapchat16.5%
MessagingFacebook VoIP14.3%
MessagingLINE12.1%
MessagingSkype4.1%
MessagingOther21.6%
WebGoogle41.2%
WebOther58.8%

The world’s tech giants had the leading app in the four biggest data streaming categories. Alphabet’s YouTube and Google made up almost half of all video streaming and web browsing traffic, while Facebook’s own app, combined with Instagram and WhatsApp, accounted for 93% of global social networking traffic and 45% of messaging traffic.

Traffic usage by app highlights the data monopoly of tech giants and internet providers. Since just a few companies account for a majority of global smartphone internet traffic, they have a lot more bartering power (and responsibility) when it comes to our general internet consumption.
