dataSTICKIES are the next generation of data portability. They are graphene-based flash drives that replace USB pen drives and hard discs.
USB-based drives can be inconvenient to use as the positioning and insertion of the drive in the USB slot needs to be done precisely. When the slots are at the rear of a device, as is the case for many desktop computers, this task becomes even more troublesome.
dataSTICKIES solve this problem by carrying data like a stack of sticky-back notes. Each of the dataSTICKIES can be simply peeled from the stack and stuck anywhere on the optical data transfer surface (ODTS), which is a panel that can be attached to the front surface of devices like computer screens, televisions, music systems, and so on. The special conductive adhesive that sticks the dataSTICKIES to the ODTS is the medium that transfers the data. This special low-tack, pressure-sensitive adhesive is capable of being reused without leaving marks like a repositionable note. When the dataSTICKIES are being read by the device, their edges light up.
Ist es Wahr?
Cotard Delusion is a rare disorder in which the affected people experience one or more of a number of delusions including that they are dead, do not exist, have lost body parts, blood or organs, or that they have lost their soul.
Patients, when asked how they are able to walk and talk and interact seem confused and unable to understand how that’s possible but will maintain their belief.
In 2006 a man identified as Graham attempted suicide by taking a toaster into the bathtub with him. He did not succeed in ending his life, but he believed that he had. When he woke, he believed that his brain was, fried in the bathtub, and that he was dead.
"When I was in hospital I kept on telling them that the tablets weren’t going to do me any good ‘cause my brain was dead. I lost my sense of smell and taste. I didn’t need to eat, or speak, or do anything. I ended up spending time in the graveyard because that was the closest I could get to death."
Using PET scans doctors assessed his brain, the first brain scans of a person with Cotard Syndrome they found that Metabolic rates of his brain were so low it was functioning as if he was in a vegetative state, under anesthesia, or asleep.

Despite often-present budget problems, NASA and the scientific community remain hopeful. Buzz abounds regarding manned lunar missions - potentially to the Earth-moon L2 Lagrange point (60,000 kms above the far side surface) in 2021 and a manned far side surface mission by 2028.David Kring, planetary scientist at the NASA-funded Lunar and Planetary Institute (LPI) in Houston, says that while there’s currently no formal NASA funding for a specific crewed lunar mission, the agency has already planned space-based tests for the Orion spacecraft.Having been nearly 40 years since Apollo 17 left the lunar near side, Kring continues that such long manned absences from the lunar surface have been a hindrance to all of planetary science.Some lunar science priorities include testing the Lunar Cataclysm hypothesis, the Giant Impact lunar-formation hypothesis, figuring out how old the 2500 km-diameter South Pole Aitken Basin truly is, and exploration of the Schrodinger crater.
It’s been a long time since we’ve been to the Moon. Let’s try to get there faster by telling Congress that NASA deserves a doubling of it’s funding.

When you are typing away at your computer, you don’t know what your fingers are really doing.
That is the conclusion of a study conducted by a team of cognitive psychologists at Vanderbilt and Kobe universities. It found that skilled typists can’t identify the positions of many of the keys on the QWERTY keyboard and that novice typists don’t appear to learn key locations in the first place.
“This demonstrates that we’re capable of doing extremely complicated things without knowing explicitly what we are doing,” said Vanderbilt University graduate student Kristy Snyder, the first author of the study, which was conducted under the supervision of Centennial Professor of Psychology Gordon Logan.
A description of the research will appear in an upcoming issue of the journal Attention, Perception & Psychophysics, which recently posted it online.
The researchers recruited 100 university students and members from the surrounding community to participate in an experiment. The participants completed a short typing test. Then, they were shown a blank QWERTY keyboard and given 80 seconds to write the letters in the correct location. On average, they typed 72 words per minute, moving their fingers to the correct keys six times per second with 94 percent accuracy. By contrast, they could accurately place an average of only 15 letters on a blank keyboard.
The fact that the typists did so poorly at identifying the position of specific keys didn’t come as a surprise. For more than a century, scientists have recognized the existence of automatism: the ability to perform actions without conscious thought or intention. Automatic behaviors of this type are surprisingly common, ranging from tying shoelaces to making coffee to factory assembly-line work to riding a bicycle and driving a car. So scientists had assumed that typing also fell into this category, but had not tested it.
What did come as a surprise, however, was a finding that conflicts with the basic theory of automatic learning, which suggests that it starts out as a conscious process and gradually becomes unconscious with repetition. According to the widely held theory – primarily developed by studying how people learn to play chess – when you perform a new task for the first time, you are conscious of each action and store the details in working memory. Then, as you repeat the task, it becomes increasingly automatic and your awareness of the details gradually fades away. This allows you to think about other things while you are performing the task.
Given the prevalence of this “use it or lose it” explanation, the researchers were surprised when they found evidence that the typists never appear to memorize the key positions, not even when they are first learning to type.
“It appears that not only don’t we know much about what we are doing, but we can’t know it because we don’t consciously learn how to do it in the first place” said Logan.
Evidence for this conclusion came from another experiment included in the study. The researchers recruited 24 typists who were skilled on the QWERTY keyboard and had them learn to type on a Dvorak keyboard, which places keys in different locations. After the participants developed a reasonable proficiency with the alternative keyboard, they were asked to identify the placement of the keys on a blank Dvorak keyboard. On average, they could locate only 17 letters correctly, comparable to participants’ performance with the QWERTY keyboard.
According to the researchers, the lack of explicit knowledge of the keyboard may be due to the fact that computers and keyboards have become so ubiquitous that students learn how to use them in an informal, trial-and-error fashion when they are very young.

I know I’m a science blog and blah blah blah but as an African, humanitarian and a human on this planet, I would like to acknowledge the passing of a wonderful man. I’ve admired this man for a long time and I am extremely sad that this world is losing another inspirational and (positively) influential person because we had so few to begin with. I hope people never forget his struggle and never stop struggling for a better life for themselves and others and I hope people take his advice and make an effort to make a change. Obviously you can’t save the world and most of us won’t be world famous but everyone has the capacity to make a positive change, for the science people who follow me, you know science is unbiased and impartial. It can be used for good or evil, to hurt and kill or cure and protect and I believe it is not only our responsibility to try and use science for good but also to help others who have become alienated from science, feel as if they will never be able to understand science or are afraid to learn science, understand. I hope that those of us who have an understanding can and will find ways to invite others into that understanding and love for science and encourage people to learn, reaching out into more contemporary and unconventional ways of learning (more traditional ways tend to make science dry and confusing). Sorry for the super cheesy typing and off topic stuff (don’t send me hate mail). Danke
