Medieval bishop’s theory resembles modern concept of multiple universes
A 13th century bishop’s theory about the formation of the universe has intriguing parallels with the theory of multiple universes. This was uncovered by the the Ordered Universe project at Durham University, which has brought together researchers from humanities and the sciences in a radically collaborative way. The project explores the conceptual world of Robert Grosseteste, one of the most dazzling minds of his generation (1170 to 1253): sometime bishop of Lincoln, church reformer, theologian, poet, politician, and one of the first to absorb, teach and debate new texts on natural phenomena that were becoming available to western scholars. These texts, principally the natural science of the greek scholar Aristotle, were translated from Arabic into Latin during the course of the 12th and 13th centuries, along with a wonderful array of material from Islamic and Jewish commentators. They revolutionised the intellectual resources of western scholars, posing challenges to established ways of thinking. We now recognise that the thinking they stimulated prepared the way for the scientific advances of the 16th and 17th centuries, too. Nearly 800 years later the example of Grosseteste’s works provides the basis for doing great interdisciplinary work, offering unexpected challenges to both modern scientists and humanities experts alike, especially in working closely together.

How restaurants, low-cal labels, candles, music, and even salads fool us into unhealthy eating.
In 1998, researchers from the University of Pennsylvania published a study that might strike you as kind of mean. They took two people with severe amnesia, who couldn’t remember events occurring more than a minute earlier, and fed them lunch. Then a few minutes later, they offered a second lunch. The amnesic patients eagerly ate it. Then a few minutes later, they offered a third lunch, and the patients ate that, too. Days later, they repeated the experiment, telling two people with no short-term memory that it was lunch time over and over and observing them readily eat multiple meals in a short period of time. This might seem like a somewhat trivial discovery, but it unveils a simple truth about why we eat. Hunger doesn’t come from our stomachs alone. It comes from our heads, too. We need our active memories to know when to begin and end a meal. While our stomachs know exactly what food we’re eating (since they’re the organ responsible for processing it) our brains are a bit more easily tricked. In this month’s Journal of Consumer Research, two studies on our brains and food open a crack into a depressing world of the eating brain’s awful gullibility.

A recent study shows that children are adept at absorbing swearwords. That’s the power of linguistic taboos for you

Most of the time, words behave themselves. They’re just a useful arrangement of sounds in our mouths, or letters on a page. They have no intrinsic power to offend. If I told you that skloop was a vile swearword in some foreign language, with the power to empty rooms and force ministerial resignations, you might laugh. How could an arbitrary combination of sounds have such force? But then think of the worst swearwords in your own language and you quickly understand that something else is at play here. Our reaction to them is instant and emotional. Which is why parents will not necessarily rejoice at the findings of a study by Timothy Jay, who looked at the range of “bad” words used by children as young as one. Between the ages of one and two, in fact, Jay’s experiments showed that boys drew on a vocabulary of six such words; girls eight. This expanded rapidly, with five to six-year-old boys using 34 words, and girls of the same age 21. Parents tend to want to protect children from swearwords. We’ve probably all experienced the awkwardness of swearing in front of the children of friends we forgot were there. But Jay’s study suggests the impulse is futile, at least if we believe it’ll stop them learning the words at all. What it might do, however, is teach them about context. There’s a time and a place for swearing, and a sense of taboo can help children understand that society expects different standards of behaviour in different surroundings.
Gene therapy aids performance of cochlear impants in guinea pigs.
Gene therapy delivered to the inner ear can help shrivelled auditory nerves to regrow — and in turn, improve bionic ear technology, researchers report today in Science Translational Medicine1. The work, conducted in guinea pigs, suggests a possible avenue for developing a new generation of hearing prosthetics that more closely mimics the richness and acuity of natural hearing.

Farms in upstate New York and elsewhere are using automatic milkers that scan and map the underbellies of cows, extract the milk, and monitor its quality, without the use of human hands.
The cows seem to like it, too.
Robots allow the cows to set their own hours, lining up for automated milking five or six times a day — turning the predawn and late-afternoon sessions around which dairy farmers long built their lives into a thing of the past.
With transponders around their necks, the cows get individualized service. Lasers scan and map their underbellies, and a computer charts each animal’s “milking speed,” a critical factor in a 24-hour-a-day operation.
The robots also monitor the amount and quality of milk produced, the frequency of visits to the machine, how much each cow has eaten, and even the number of steps each cow has taken per day, which can indicate when she is in heat.
“The animals just walk through,” said Jay Skellie, a dairyman from Salem, N.Y., after watching a demonstration. “I think we’ve got to look real hard at robots.”
Many of those running small farms said the choice of a computerized milker came down to a bigger question: whether to upgrade or just give up.

According to the World Health Organization, approximately 107 million blood donations are collected globally every year. Nonetheless, blood is often in short supply – particularly in developing nations. Despite new safeguards, there’s also still the risk of incompatibility, or of infections being transmitted from donors to recipients. Charitable organization the Wellcome Trust hopes to address these problems, by developing the ability to manufacture blood outside of the body. Last week, it announced that test subjects should begin receiving transfusions of blood made with lab-grown red blood cells by late 2016.
The research program is being led by the Scottish National Blood Transfusion Service, thanks to the Wellcome Trust’s £5 million (US$8.4 million) Strategic Award grant. Institutions collaborating on the project include the University of Glasgow, the University of Edinburgh, Loughborough University, NHS Blood and Transplant, the Irish Blood Transfusion Service, Roslin Cells Ltd and the Cell Therapy Catapult, in collaboration with Bristol University and the University of Cambridge.

The extent of Shakespeare’s legacy 450 years on from his birth is incalculable. But this, of course, does not stop some from trying. To many the crown of Britain’s cultural output, Shakespeare is integral to our very language, widely celebrated, studied, acted, seen. So sourcing hard evidence on the cultural value of Shakespeare is a fool’s game, if a fun one. To start with, both the words in the concept of “cultural value” are so overloaded, so controversial, that real figures for either of them are impossible to find. Are we talking about the anthropological or the aesthetic version of culture? Are we in the realm of economic use, exchange, symbolic or discursive value? And Shakespeare? Are we referencing the texts, the editions, the amateur and professional productions, or the stories, the adaptations, the movies? The only evidence we have is about the life, writing and social relationships of the writer. And this cannot hope to explain the crazy variety of ideas and objects that shelter under the most famous name in history. Shakespeare’s plays came to dominate the cultural production of later times by providing free content for the new theatres that opened after the theatrical lock-down of the English civil war. In their printed version, they became a point of reference for those who claimed the supremacy of English writing in contests with classical literature. They also provided useful, out of copyright, texts for the hugely expanded literature market created by universal education.

Any mention of cyborgs or superpowers evokes fantastical images from the realms of science fiction and comic books. Our visions of humans with enhanced capabilities are borne of our imaginations and the stories we tell. In reality, though, enhanced humans already exist … and they don’t look like Marvel characters. As different human enhancement technologies advance at different rates, they bleed into society gradually and without fanfare. What’s more, they will increasingly necessitate discussion about areas that are often overlooked – what are the logistics and ethics of being superhuman? Gizmag spoke to a number of experts to find out.
Our natural tendency is to focus on the functionality of enhanced humans. Abilities like super-strength, flight or telepathy seem so far removed from that of which we’re capable and so desirable that it’s understandable for us to focus on these possibilities. The individual, social and ethical consequences of enhanced humans are considered far less in popular culture, however.
"People tend to imagine the current state of human enhancement as either much more advanced or retarded than it really is," Steve Fuller, Auguste Comte Chair in Social Epistemology in the Department of Sociology at the University of Warwick, tells Gizmag. "I realize that this sounds paradoxical, but generally speaking it helps to explain the curious blend of impatience and disappointment that surrounds the topic. This simply reflects the fact that people know more about human enhancement from its own hype and science-fictional representations – which can be positive or negative – than from what’s actually available on the ground."
