Superhero Vision With Graphene Contact Lenses?

Graphene, a 2-dimensional crystalline allotrope of carbon, is capable of detecting the entire infrared spectrum with visible and ultraviolet light therefore it could be used to enhance human vision although there have been technical limitations such as the fact that it can absorb only 2.3 percent of the light that hits it. This problem seems to be solved now by researchers at the University of Michigan.

To achieve this amplification, the researchers started by sandwiching an insulator between two sheets of graphene. The bottom sheet has an electrical current running through it. When light hits the top sheet, electrons are freed and positively charged electron holes are generated. The electrons are able to perform a quantum tunneling effect through the insulator layer, which would be impenetrable in classical physics.

“If we integrate it with a contact lens or other wearable electronics, it expands your vision,” Zhong said in the release. “It provides you another way of interacting with your environment.”

I’ve told you in my recent white paper, The Guide to the Future of Medicine, we would soon experience the rise of “recreational cyborgs” with augmented human capabilities just because they can afford it.

Google Glass Through a Surgeon’s Eyes: Prezi

I’ve been massively writing about the potentials of Google Glass in healthcare and while I got an invitation, I couldn’t test it myself as I’m not a US citizen.

This prezi gives you a clear picture about what surgeons would expect from wearing Google Glass. But here are 3 other examples.

When Technological Developments Are Faster Than Our Imagination

We are all working hard on implementing digital solutions in healthcare and everyday practices, create new solutions to access medical records online and with mobile technologies. Sometimes futurists come up with quite brave ideas about making future technologies available, but when technological advances are just faster than our imagination, I start to smile.

Accessing patient data at the right time with a secure system is a real challenge. Some doctors use tablets, patients use wearable technologies, therefore developing a solution that suits everyone’s needs is complicated.

But what if you can just project a touchscreen wherever you want to? It could truly revolutionize the way we access and create electronic medical information and data.

Instead of being tethered to your hardware, WorldKit is designed to make access to computing instant and mobile by making the world your touchscreen. Right now, the system involves a ceiling-mounted camera and projector that record hand movements and then project onto the surface of your choice. Some potential uses include TV remote controls, which can be accessed by rubbing the arm of a sofa, or calendars that can be swiped onto doors.

Map of the Internet: With Medical Websites

A Russian developer created a new map of the internet on which if you do a search for medical websites, you will find a tiny network of relevant websites. Here is how the map was designed:

 The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.

Visualizing a medical Twitter hashtag: MDChat

I’ve recently got in touch with an amazing group, the Thesys Group. They invited me to their HQ to show me what kind of projects they are working on and we started a bit of brainstorming about what we could come up with together.

In our first project, the Thesys Group analyzed the network of discussions focusing on one of the most popular medical Twitter hashtags, MD_chat. In the figure below, a dot represents a Twitter user, lines connecting the dots represent their relationship. The bigger the dot is, the more tweets the Twitter user had. The thicker the line is, the more tweets the two users had with each other. Based on this, here is the network graph (click on the image below to access the interactive graph):

Dots in the middle account for active users, while dots in the periphery did not participate that often in these discussions. Graph includes only tweets including user names, therefore representing discussions.  Here is a zoomed version of this graph just to show you how the dots are connected to each other on a smaller scale with @doctor_v and @jodyms in the focus.

A few numbers and facts:

  • Tweets are dated between October, 2010 and October, 2011 (4815 messages).
  • Data tables were obtained from a public Scridb database containing all the MD_chat discussions and can be downloaded in doc or PDF formats.
  • 282 users are represented in the graph with 1972 connecting them to each other.
  • Graph was visualized with the Gephi open-source platform.

The top 10 most active Twitter user using the MD_chat hashtag in discussions (largest dots in the graph):

Rank MD chat user name Number of addressed tweets
1 richmonddoc 559
2 ellenrichter 204
3 gailzahtz 190
4 peds_id_doc 181
5 mdstudent31 178
6 apjonas 159
7 ability4life 155
8 westr 145
9 chukwumaonyeije 140
10 md_chat 139

The aim of this short study was to point out the importance of medicine related hashtags and the growing popularity of these. The dynamic growth of MD_chat is a good example for the changes that we can see now in the everyday communication among peers. Therapeutic experience, news and opinions spread without geographical or linguistic limitations.

Please let us know what you think of this analysis and feel free to contact me or the Thesys Group for more details.

Visualizing Disease Data

It’s quite clear not everyone would like to read long medical reports and text as sometimes a well-designed and structured graph can say more than a hundred words. Do you remember the Wired article about the blood test makeover that described how our blood test results would be designed to show more easily understandable information to patients?

Well, this Venn diagram shows many things about Hemorrhoids and related symptoms. And it’s not even a new infographics published on a blog but is from an old textbook which means the concept has been there for a long time but it always disappears in medicine.

 

Saving Medicare is Visualized

It seems everyone in the US has a plan for saving Medicare, but this budget visualization looks really great.

This video lays out the clear choice United States of America faces on Medicare: “Will Medicare become a program in which a board of bureaucrats manages its bankruptcy by denying care to seniors?

Minimal Style Posters about Mental Disorders

Patrick Smith did some research about mental disorders and decided to try to visualize these conditions through minimal style posters. Amazing job! Here is one example:

200 Healthcare Systems in 4 Minutes

Hans Rosling, director of the Gapminder Foundation, just released another spectacular video featuring 200 years of 200 healthcare system with 12,000 numbers in 4 minutes. Enjoy:

Biological Cinema

New York Times published an article about molecular animators, scientists who can visualize the microscopic segments of life in a professional way.

If there is a Steven Spielberg of molecular animation, it is probably Drew Berry, a cell biologist who works for the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia. Mr. Berry’s work is revered for artistry and accuracy within the small community of molecular animators, and has also been shown in museums, including the Museum of Modern Art in New York and the Centre Pompidou in Paris. In 2008, his animations formed the backdrop for a night of music and science at the Guggenheim Museum called “Genes and Jazz.”

“Scientists have always done pictures to explain their ideas, but now we’re discovering the molecular world and able to express and show what it’s like down there,” Mr. Berry said. “Our understanding is just exploding.”
