Switched-on DNA: Sparking nano-electronic applications

“It has been established that charge transport is possible in DNA, but for a useful device, one wants to be able to turn the charge transport on and off. We achieved this goal by chemically modifying DNA,” said Tao, who directs the Biodesign Center for Bioelectronics and Biosensors and is a professor in the Fulton Schools of Engineering. “Not only that, but we can also adapt the modified DNA as a probe to measure reactions at the single-molecule level. This provides a unique way for studying important reactions implicated in disease, or photosynthesis reactions for novel renewable energy applications.”

Engineers often think of electricity like water, and the research team’s new DNA switch acts to control the flow of electrons on and off, just like water coming out of a faucet.

Previously, Tao’s research group had made several discoveries to understand and manipulate DNA to more finely tune the flow of electricity through it. They found they could make DNA behave in different ways—and could cajole electrons to flow like waves according to quantum mechanics, or “hop” like rabbits in the way electricity in a copper wire works —creating an exciting new avenue for DNA-based, nano-electronic applications.

The Dunning-Kruger effect: why do incompetent people think they are so great? or Unskilled and unaware of it: How difficulties in recognizing one’s own incompetence lead to inflated self-assessments.

People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd. Several analyses linked this miscalibration to deficits in metacognitive skill, or the capacity to distinguish accuracy from error. Paradoxically, improving the skills of the participants, and thus increasing their metacognitive competence, helped them recognize the limitations of their abilities.

Easy Solutions: So, you’re in love with one of your friends, but she has a boyfriend and probably wouldn’t have sex with you anyway.

Easy Solutions #1

So, you’re in love with one of your friends, but she has a boyfriend and probably wouldn’t have sex with you anyway.

What you will need: 1 x knife, 1 x ring, access to a sunbed, the ability to grow a beard.

Step One: Place the ring on your wedding finger and avoid contact with your friend for a month.

Step Two: Stop shaving and use the sunbed to gain a tan.

Step Three: After a month when your beard is full and your tan is noticeable, remove the ring from your finger.

Step Four: Remove all your clothes and break into your friend’s house.

Step Five: Use the knife to cut your body in various places. Avoid the face. If possible, focus on your back. The more blood the better.

Step Six: Enter your friend’s bedroom and lie face down on the floor. Wait for her return.

Step Seven: When she enters the room pretend to be unconscious. Allow her to turn you over and try to wake you for a few seconds before you open your eyes. The injuries to your body will serve as a distraction to your nakedness. She will be more concerned about your wellbeing instead of fearing the naked man in her room.

Step Eight: When she asks you what’s happened you should ignore her questions. Instead you must act confused and ask the date. If it’s September 15th she will say ‘September 15th’ to which you must reply ‘No, what year is it?’

Step Nine: Upon hearing the year say the words ‘It worked.’ Pretend to lose consciousness again for a few seconds, implying that whatever it is that has worked took a great effort.

Step Ten: If your friend is a curious person she will probably ask ‘What worked?’, even if she doesn’t ask this question it is important that you now say the words ‘(Insert Friend’s Name), I’m from the future’ in your most deadpan voice.

Step Eleven: Pause for ten seconds to allow the incrediblness of the situation to sink in. There will be no reason for her to doubt your claim, because your beard will make you appear many years older and your cuts would add weight to the idea that you’ve come from a post-apocalyptic future where a war is currently taking place.

Step Twelve: Raise your left hand to your face. All women are very observant, so your friend will immediately notice the tanline on your wedding finger. If she is educated to a decent standard she will realise that you are married and your ring has simply disappeared, because clothing and other items cannot travel through time. Your nudity will support this.

Step Thirteen: Now comes the hard part – The monologue. In your own words you must give a speech in which you mention all of these key points:

a) You are married to each other in the future
b) Her current boyfriend is dead
c) The world is coming to an end. It’s up to you to pick a reason, but I would recommend a war against machines. This whole situation will be backed up by the Terminator franchise
d) In the future your relationship is not going well
e) You’ve come back in time because you can’t help but feel that she would have been happier with her current boyfriend if he hadn’t been killed
f) Her current boyfriend is going to be hit by a bus on a day six months from her present. She should stop him going to work that day
g) If she does exactly what you say this current version of yourself will be erased and you will never get married. If she questions this flaw in your time travel logic, because you cannot change the past, simply reference Back to the Future

Step Fourteen: Unless your friend is made of stone she will now be overcome by emotion, especially at your selflessness. Get to your feet and go to kiss her goodbye. It is important that you do this with the confidence of a man who has done this to her many times.

Step Fifteen: There is now no possible way that you aren’t about to have sex with her. You’re naked, kissing her, in her bedroom, agreeing to erase a version of yourself from history to make her happy. And as far as she knows you’ve had sex many times in a future that will no longer happen, so she thinks to herself that maybe she should have one memory of it.

Step Sixteen: After having the sex, ask to borrow some clothes then leave.

Step Seventeen: Shave off your beard and coat your wedding finger in fake tan. Carry on as if nothing has happened. There will be three possible outcomes:

1) During the sex some feelings that she didn’t know existed are awakened and she will leave her boyfriend for you.
2) Life will carry on as normal.
3) You will be filled with guilt because of this moral grey area where you aren’t entirely sure if what you’ve done counts as some kind of low level rape. You will take your own life by hanging, overdose or wrist cutting.
