Hoping to give new meaning to the term “natural light,” a small group of biotechnology hobbyists and entrepreneurs has started a project to develop plants that glow, potentially leading the way for trees that can replace electric streetlamps and potted flowers luminous enough to read by.
The project, which will use a sophisticated form of genetic engineering called synthetic biology, is attracting attention not only for its audacious goal, but for how it is being carried out.
Rather than being the work of a corporation or an academic laboratory, it will be done by a small group of hobbyist scientists in one of the growing number of communal laboratories springing up around the nation as biotechnology becomes cheap enough to give rise to a do-it-yourself movement.
The project is also being financed in a D.I.Y. sort of way: It has attracted more than $250,000 in pledges from about 4,500 donors in about two weeks on the Web site Kickstarter. (via A Dream of Glowing Trees Is Assailed for Gene-Tinkering - NYTimes.com)

Reblogged before, but worth an update: These guys got more than funded, with still 28 days to go. Not bad for a DIY biotech lab.

15 year old invents new method of diagnosing cancer

stfuhypocrisy:

Innovation doesn’t care how old you are.

I’d like you to meet Jack Andraka. It’s a name you will be hearing a lot about–today, tomorrow and in the future.

Jack is a scientist and innovator. And his work on creating a simple test for the identification of pancreatic, lung and ovarian cancer is simply amazing.

Here are some of his facts:

  • -His test is 168 times faster than what is currently available.
  • -It’s 26,000 times less expensive. That’s not a typo.
  • -And it’s potentially almost 100% accurate.

Here’s what makes it even more astonishing:

  • -Jack is 15 years old.

So, I just had to speak with Jack. I tweeted him. His reply was swift and caught me off guard. ”That would be awesome! I get off school today at 2:15.” I had been caught up in the clinical implications and had forgotten that Jack was still a student.

Jack recognized that mesothelin is a key market to certain cancers. To create his test, Jack mixed human mesothelin-specific antibodies with carbon nanotubes and coated strips of ordinary filter paper.

 
                   
 

What resulted was a simple “dip-stick” tool similar to what a patient with diabetes might use to measure blood sugar.

But let’s hear the story directly from him:

–How did you first get interested in science and particularly cancer?

I was interested in science at an early age because my parents would never answer my questions but always helped me to discover or find out answers for myself. So I learned how to make hypotheses and test them without knowing I was ‘doing science’!

I became interested in cancer, particularly pancreatic cancer, after my ‘uncle’, a close family friend, died due to the disease. After researching about it, I discovered that 100 people die of pancreatic cancer every day and that although early detection is key to improved survival, there are no inexpensive, rapid and sensitive tests. I figured there had to be a better way.

–Who or what encouraged you to take this challenge on?

I really enjoy challenges and particularly enjoy looking for elegant and simple solutions to seemingly complex problems. I do a lot of math competitions and my math coaches always tell us that although you can use brute force to solve a problem that looks really complex you should think about other tools and figure out a more elegant way to solve it. My math heroes can reduce a really difficult proof to a few elegant lines.

So with that mindset I thought and thought about this new problem.

–Do people feel that your innovation is somehow less important because of your age?

I don’t think people feel my innovation is less important because of my age. They can see that it is a great idea. When I go to conferences I feel there is a subtle ‘age-ism” though because at the pre-talk meetings, it seems that people think I’m a speaker’s child tagging along but after I speak then I get to have the most amazing conversations. That’s why the internet is so great – people can’t see what age or race you are and I can have a great exchange of information.

–Was your discovery easy? Did the innovation come in a flash…then the details worked out?

I like to read a lot of journals and articles about different topics and then lie on the couch or take a walk and just let all the information settle. Then all of a sudden I can get an idea and connect some dots. Then it’s back to reading so I can fill in missing pieces. With this sensor I had put in a lot of time learning about nanoparticles for my previous research on the effects of bulk and nano metal oxides on marine and freshwater organisms. I felt that single walled carbon nano tubes were like the super heroes of material science and I wanted to work with them some more. Then when I was reading a paper about them in biology class, the teacher was explaining about antibodies. All of a sudden I made a connection and wondered what would happen if I dispersed single wall carbon nanotubes with an antibody to a protein over-expressed in pancreatic cancer. Then of course there was a lot of reading, learning and planning in front of me!

–How did your “rejections” help drive you? Or frustrate you?

I had visited ISEF when my brother was competing and talked to kids who mentioned they had done their work in a lab. It seemed so easy so I stalked the internet and found the names and professional emails of lots of professors in my area who were working on pancreatic cancer. Then I just figured I’d sit back and wait for the acceptances to roll in! Week after week I’d receive endless rejections. The most helpful one was actually from a researcher who took the time to point out every flaw and reason why my project was impossible. I began to despair!

–What is the role of mentors in helping you?

Finally, after 199 rejections, I received one email from Dr Maitra at Johns Hopkins School of Medicine. He invited me to come for a meeting. My mom drove me there and dropped me off. It was pretty exhilarating yet scary to walk in to the interview! Luckily I was really prepared and even had the cost and catalog numbers of the material I needed. He said it was like reading a grant proposal. I still had a great deal of basic lab routine to learn and I appreciate the time and patience of both Dr Maitra and Dr Chenna, the post- doc who supported me.

–What do you think about science as the driver of your fame?

I’m very surprised that people know about me. My original goal was to see if I could make a simple inexpensive sensor to detect pancreatic cancer because too many people were dying. I’m very happy that I’m known for science though because I enjoy sharing and learning about it so much. I hope kids feel ‘if Jack can do this, what can I do?’ and get inspired to take on big challenges in their own lives and communities.

–How has your world expanded from this innovation?

These past few months have been life changing. I’ve met so many of my heroes in math, science, and politics, including the Clintons when I spoke at the Clinton Global Initiative. I’ve traveled all over by myself and learned how to enjoy speaking and sharing my ideas with large audiences. One of my most world- expanding experiences came very quickly when I went to Singularity U in California. I met people who weren’t afraid of failure, but just used failure to say well that path didn’t work and moved on. I met people who were trying to improve the world for billions of people. They were starting businesses and thinking big and supporting each other. They told me about the Thiel Fellowship and opened my eyes to different ways of accomplishing goals. I’ve learned to look outside myself and my small community to the larger world and think about how I can help change the world for the better.

–What’s next for Jack?

I’m working on my next project but of course it isn’t coming easily! Professors still reject me from their labs saying that I don’t know enough, perhaps not even reading my proposal but just seeing ‘high school student’ on the proposal. But even great researchers still don’t always get accepted for every grant. Perseverance still counts! I’m trying to get a group of teens to work on the Tricorder X prize as ‘Generation Z’ and it’s difficult finding like-minded teens who can bring something to the table and who also have time in their over scheduled lives. I’m speaking at the Royal Society of Medicine in London and then at TED at Long Beach this month, talking with different biotech companies about producing my sensor and starting my first business. And of course there’s homework to be done!

Well done Jack!

One final thought about Mr. Andraka. I believe a more appropriate name for this post would be “Health, Innovation and a Man Named Jack”.

It’s been a big week for poop science …

jtotheizzoe:

Thankfully, most of us don’t go through our day puckered in fear that we might, at any unknown moment, loose our bowels in a Niagara-esque outpouring of one’s colon contents. But for people with Clostridium dificile infections, that is a clear and present danger.

It’s not just the discomfort of frequent and recurring diarrhea that plagues those with C. diff. They are at real risk of damaging their colon tissue from inflammation as well as serious dehydration. Even worse, C. diff. is hard to kill with antibiotics, as it most often rears its anaerobic head when a patient has had their normal gut flora killed off by previous antibiotic treatment, leaving the colon a lawless Wild West for the tiny diarrhea bandits to take over.

There is good news, though (see below)! The Wyatt Earp in this (south)-Western is being played by fecal transplants.

Yep. In a fecal transplant, C. diff colons are seeded with donated (purified) fecal material, and all the healthy bacteria therein, and they fight off the bad guys. Not a very intriguing opportunity, eh? Well, if you’ve ever had a C. diff. infection, I hear you’d change your mind pretty fast.

The news:

  1. A clinical trial in Europe for fecal transplants was halted early … because it worked so well! People in the placebo group were like “Hey, that guy’s getting better really fast. Damn! I’m in the placebo group! Hey doc, give me some of that gravy!
  2. A separate team of scientists has developed a “pseudo-poo” to take the “poo donors” out of the equation. By infusing a solution full of the 33 most helpful gut bacteria, two women were cured of their C. diff infections!

These scientists must be swollen full of pride, about ready to gush thanks to this outpouring of amazing results! 

But seriously, fighting bad poo with good poo? Nature, you work in mysterious ways. I like that. Keeps it interesting.

Acoustic Levitation

Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn’t get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this “containerless processing”.

The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic pressure is enough to cancel the force of gravity.

Things you should know about me: I can never get enough of ferrofluids. After you check out this art exhibit, here’s more examples of these amazing fluid-magnetic creations.

Sachiko Kodama: The Art and Science of Ferrofluid

Sachiko Kodama explores within her artwork ‘The Art and Science of Ferrofluid’ the pulsating nature of science and amorphous character of time and space based on the shape of magnetic waves…

The Japanese female artist Sachiko Kodama was born in 1970. As a child she spent a lot of time in the southernmost part of Japan. This area is rich in tropical flowers and plants, edged by the sea, and washed with warm rain. Sachiko loved art and literature from an early age, but also had a strong interest in science.

After Graduating Physics course in the Faculty of Science at Hokkaido University, in 1993, Sachiko matriculated in the Fine Arts Department at the University of Tsukuba, studying Plastic Art and Mixed Media. Then she completed Master’s and Doctoral Program in Art and Design at the University of Tsukuba. She studied Computer and Holography Art in her doctoral research.

‘Ferrofluids appear as black fluid and are made by dissolving nanoscale ferromagnetic particles in a solvent such as water or oil. They remain strongly magnetic even in a fluid condition which makes them more flexible than iron sand.’

Reader kylewpppd asks:

Have you seen the post of a man in Siberia throwing boiling water off of his balcony? Can you provide a better explanation of what’s going on?

As you can see in the video (and in many similar examples on YouTube), tossing near boiling water into extremely cold air results in an instant snowstorm. Several effects are going on here. The first thing to understand is how heat is transferred between objects or fluids of differing temperatures. The rate at which heat is transferred depends on the temperature difference between the air and the water; the larger that temperature difference is the faster heat is transferred. However, as that temperature difference decreases, so does the rate of heat transfer. So even though hot water will initially lose heat very quickly to its surroundings, water that is initially cold will still reach equilibrium with the cold air faster. Therefore, all things being equal, hot water does not freeze faster than cold water, as one might suspect from the video.

The key to the hot water’s fast-freeze here is not just the large temperature difference, though. It’s the fact that the water is being tossed. When the water leaves the pot, it tends to break up into droplets, which quickly increases the surface area exposed to the cold air, and the rate of heat transfer depends on surface area as well! A smaller droplet will also freeze much more quickly than a larger droplet.

What would happen if room temperature water were used instead of boiling water? In all likelihood, a big cold bunch of water would hit the ground. Why? It turns out that both the viscosity and the surface tension of water decrease with increasing temperature. This means that a pot of hot water will tend to break into smaller droplets when tossed than the cold water would. Smaller droplets means less mass to freeze per droplet and a larger surface area (adding up all the surface area of all the droplets) exposed. Hence, faster freezing!
