Designer Avery Holleman has developed the concept of a Napkin PC, a device that uses e-paper and radio frequency (RF) technology to enable creative groups to collaborate more effectively. The technology includes a “napkin” holder filled with e-paper napkins, as well as a place for colored pens. When someone gets an inspiration, they simply grab a napkin and start doodling with one of the pens. The pen uses short-range RF technology to send data to the napkin interface. The pen and napkin can also communicate to a base station PC in the napkin holder using long-range RF.Holleman hopes that the Napkin PC concept could enable creative groups – such as architects, artists, and engineers – to collaborate better because the doodles can be easily shared. Another perk of the concept is that the napkins are modular, so designers can connect them to create large-scale layouts. For example, a block of napkins can be hung side by side on a wall to create a large display.Another advantage is that the Napkin PC requires very little power. It doesn´t even use a battery, but instead relies on a single-layer flexible circuit board for inductive power. The pen itself wirelessly powers the napkin when it comes within close range. The e-paper napkins can retain their bright, full-color images without power for an indefinite period of time.When doodling, users can sign their name on any napkin to load personal features such as settings and bookmarks. The pens also keep track of who draws what, so that credit can later be given to the appropriate person.Holleman is hoping that the concept could reduce paper waste, and cut down on the need for printers. The product would be sustainable for several years, with only the napkins occasionally needing to be replaced, which would be done in an environmentally friendly process since no batteries are involved.via: Yanko Design The Napkin PC: “No inhibitions, it´s just a napkin.” This document is subject to copyright.

Credit: Gustav Mårtensson Journal information: PLoS ONE , Nature Medicine TRMM satellite sees Tropical Storm Dylan make landfall in Queensland Jon Lundberg and Eddie Weitzberg, both professors at the Department of Physiology and Pharmacology at the Karolinska Institute, were involved in the 1997 article; Lundberg laid out the rules of the bet as “The one who has written most articles with Dylan quotes, before going into retirement wins a lunch at the Solna restaurant Jöns Jacob.”Jonas Frisén and a colleague stepped up to the plate in their 2010 article published in Cell Cycle: “Eph receptors tangled up in two” was inspired by Dylan’s “Tangled up in Blue.” One year later, Lundberg and Weitzberg wrote a paper, “Dietary nitrate – a slow train coming” for The Journal of Physiology. As if they could stop right there. In a paraphrase of Dylan, they inserted in the paper’s conclusion, “We know something is happening, but we don’t know what it is – Do we, Dr Jones?” Lundberg said they were referring to a British colleague with the same surname.The Dylan-inspired scientists have drawn attention to the articles via email. One of the competitors, Joan Frisen, said it was “important that the quote is linked to the scientific content, that it reinforces the message and raises the quality of the article as such, not the reverse.” What could draw researchers exploring cells and inflammation to Bob Dylan? Opinions reflect high esteem for Dylan among the band of scientists, opinions that include Dylan being worthy of a Nobel prize for literature to recognition of Dylan as a modern Shakespeare. A practical parallel was drawn by Konstantinos Meletis, research assistant at the Department of Neuroscience. “A musician who merely continues down the same highway for 30 years is not one who many want to listen to,” he said in KI News. “Good music is innovative, like Bob Dylan’s. And the same thing applies to good research. A researcher must also try to find new and different paths.” News of their bet may also help to bolster the work of scientists who, in exploring the activities of the brain, wish to explore less simplistic notions about one side of the brain working toward art appreciation and the other toward algebra appreciation. A study on PLOS ONE last year from a team at University of Utah and University of Wisconsin, “An Evaluation of the Left-Brain vs. Right-Brain Hypothesis with Resting State Functional Connectivity Magnetic Resonance Imaging,” said that “our analyses suggest that an individual brain is not ‘left-brained’ or ‘right-brained’ as a global property, but that asymmetric lateralization is a property of individual nodes or local subnetworks, and that different aspects of the left-dominant network and right-dominant network may show relatively greater or lesser lateralization within an individual.” , Cell Cycle (Phys.org) —A 17-year old bet among scientists at the Karolinska Institute has been a wager that whoever wrote the most articles with Dylan quotes before they retired would get a free lunch. Results included papers such as Nitric oxide and inflammation: the answer is blowing in the wind,” published in 1997 in Nature Medicine. Then there was another cluster of members preparing an article about whether blood cells change and become nerve cells. They entered the title, “Blood on the tracks: a simple twist of fate.” The first two nitric oxide authors repeated their effort with another paper that had “The times they are a-changin’ in the title. At the same time, they emailed the “blood on tracks” authors and announced an internal competition. Lisa Reimegård chronicled their multi-year wager in KI News, the publication of the Karolinska Institute.

The researchers found that the rats undergoing tickling vocalized more and their ears became droopier and pinker—they exhibited no discernible reactions during the negative experiences. The researchers attributed the lowered ears to the rats being in a more relaxed state, but they were not clear on the reason for the pinker ears—they suggested it could have been a sign of happiness or simply increased blood flow due to the small degree of physical exertion that went along with laughing while being tickled. Why are we ticklish? As the researchers note, a multitude of studies have been conducted by scientists attempting to learn about the experience of pain or other negative emotions in rats and other animals—if researchers were aware of the pain they may be causing a rat or other test animals, they may be more likely to alter experiments to reduce animal suffering. But, as the researchers also note, very little research has been done to learn about more positive states in rats and other animals. People know when a dog is happy, for example—such pets are quite demonstrative—but how can a person tell if a pet or lab rat is happy or sad, or simply existing continually in a non-emotional state? By looking at its ears, apparently, according to the researchers with this new effort.Prior research has suggested that rats like to have their bellies tickled—they come back for more and emit a noise (in a range too high for humans to hear) that some researchers have compared to laughing. Because of that, the researchers use tickling as a basis for testing happiness in rats. They selected 15 male Lister hooded lab rats and subjected them to two types of environmental experiences they labeled as either positive or negative. The positive experiences consisted of sessions of tickling by one of the researchers; the negative experiences were more harsh—the rats were put in another room where they were subjected to random blasts of white noise. During both types of experiments, microphones were used to record vocalizations by the rats and observations were made of physical features, particularly changes to faces. Tickling procedure. The one-handed tickling procedure (a) consisted of one-handed repeated pinning, while rapidly stimulating the underside with the fingertips. The two-handed tickling procedure (b) consisted of scooping and supporting the animal with both hands, while vigorously tickling the sides and nape of the neck with the fingertips.

DOI: 10.1371/journal.pone.0166446 Journal information: PLoS ONE © 2016 Phys.org (Phys.org)—A team of researchers with the University of Bern in Switzerland has found that as part of feeling happiness, rats undergo a slight physical change. As the team notes in their paper uploaded to the peer-reviewed open access site PLOS ONE, the rats under study demonstrated happiness by lowering their ears. More information: Kathryn Finlayson et al. Facial Indicators of Positive Emotions in Rats, PLOS ONE (2016). DOI: 10.1371/journal.pone.0166446AbstractUntil recently, research in animal welfare science has mainly focused on negative experiences like pain and suffering, often neglecting the importance of assessing and promoting positive experiences. In rodents, specific facial expressions have been found to occur in situations thought to induce negatively valenced emotional states (e.g., pain, aggression and fear), but none have yet been identified for positive states. Thus, this study aimed to investigate if facial expressions indicative of positive emotional state are exhibited in rats. Adolescent male Lister Hooded rats (Rattus norvegicus, N = 15) were individually subjected to a Positive and a mildly aversive Contrast Treatment over two consecutive days in order to induce contrasting emotional states and to detect differences in facial expression. The Positive Treatment consisted of playful manual tickling administered by the experimenter, while the Contrast Treatment consisted of exposure to a novel test room with intermittent bursts of white noise. The number of positive ultrasonic vocalisations was greater in the Positive Treatment compared to the Contrast Treatment, indicating the experience of differentially valenced states in the two treatments. The main findings were that Ear Colour became significantly pinker and Ear Angle was wider (ears more relaxed) in the Positive Treatment compared to the Contrast Treatment. All other quantitative and qualitative measures of facial expression, which included Eyeball height to width Ratio, Eyebrow height to width Ratio, Eyebrow Angle, visibility of the Nictitating Membrane, and the established Rat Grimace Scale, did not show differences between treatments. This study contributes to the exploration of positive emotional states, and thus good welfare, in rats as it identified the first facial indicators of positive emotions following a positive heterospecific play treatment. Furthermore, it provides improvements to the photography technique and image analysis for the detection of fine differences in facial expression, and also adds to the refinement of the tickling procedure.

The show was curated by Surbhi Modi. The exhibition showcased the artworks and installation of eight artists.The exhibition celebrates Bacon’s notion of the ordered chaos, where the aesthetic and the anaesthetic are constantly at odds and where abstraction fights figuration, leaving us with an altered reality, which has some semblance of the familiar, yet the intrigue of the new.The title Beauty in the Beast is a Shrek-like take on the fairy tale where the ugly duckling does not become a swan, the ugly beast does not metamorphose into a handsome prince but where we brazenly glorify the grotesque. Also Read – ‘Playing Jojo was emotionally exhausting’Anant Mishra drawings meander between the dualities of human and animal, abstraction and figuration, arrogating mythical beasts and fantastical characters whereas Bhuwal Prasad’s vibrant, anarchic canvases exhort images of a familiar haze. Mangesh’s video installation combines the luxury of velvet felt with the bad-tempered of sound and video that show a delicate balance of a beast and a flower that move in a kaleidoscopic manner. His surrealistic pencil drawings are both humorous and insightful, and reflect the musings of a very wise child.Rajesh’s exquisite miniatures pay homage to Klimt but bring his own brand of melancholic nonchalance, to the forefront. Nayanna Kanoria’s oils show zebras in a living room.
Prime Minister David Cameron will this year deliver his most religious Christmas message to date, calling Britain a “Christian country” whose religious values have made it a “home to people of all faiths and none”.Cameron will focus on the issues of peace and security at a time when millions are fleeing war around the world, stressing the importance of Britain’s Christian values in shaping how the country responds.“That is what we mark as we celebrate the birth of God’s only son, Jesus Christ – the Prince of Peace,” he said. Also Read – Nine hurt in accident at fireworks show in French resort“As a Christian country, we must remember what his birth represents: peace, mercy, goodwill and, above all, hope.“I believe that we should also reflect on the fact that it is because of these important religious roots and Christian values that Britain has been such a successful home to people of all faiths and none.”The message was the second year in a row that Cameron referred to Britain as a Christian country, despite his having been accused of stoking “alienation and division” last Christmas.

Stephen Evans, the group’s campaigns manager, said: “We look to political leaders for leadership, not theology, and this kind of language reveals him to be less than statesmanlike.”He added: “David Cameron needs to appreciate that he isn’t a leader of Christians, he’s the prime minister of a diverse, multi-faith, and increasingly non-religious nation.”Cameron will use his message to draw attention to the millions of refugees fleeing war in Syria and elsewhere and the persecution of Christians around the world.“Millions of families are spending this winter in refugee camps or makeshift shelters across Syria and the Middle East, driven from their homes by Daesh and [Syrian president] Assad,” he said.“Christians from Africa to Asia will go to church on Christmas morning full of joy, but many in fear of persecution.“Throughout the United Kingdom, some will spend the festive period ill, homeless or alone,” he said. The Government has pledged to accept 20,000 of the 4 million refugees from Syria over a five year period, with the first families arriving in recent weeks.Cameron also paid tribute to people who were spending Christmas “helping the vulnerable at home and protecting our freedoms abroad”, and to the armed forces stationed abroad.
