US researchers are investigating ways to extract the gold and precious metals from human faeces.
It’s hard to read the old-fashioned way, slowly and deliberately. Few of us have the patience, the concentration, or the time. When we do read, we skim, trying to get a quick “take” on the topics of the day, often conveniently served up as prepackaged excerpts by our modern media machine. We flit from one thing to the next, never pausing to think about what we’ve just read, because in our media-saturated, technology-obsessed age we just don’t have time. Worse, our bad reading habits are symptomatic of a deeper malaise. Real learning, real knowledge, and real culture have been supplanted by the shallow, utilitarian instrumentalism of modern life. The evidence is mounting. Humanities departments are losing students to the sciences and other more useful majors, where they are stuffed with facts and outfitted with skills, better to serve the state as productive citizens; our cultural models are the average heroes of a popular culture. Our culture is in decline. And we read only the headlines. That may sound like the latest jeremiad in The New Criterion or The New Republic, but it’s actually a paraphrase of Friedrich Nietzsche’s preface to a series of lectures he delivered in the winter of 1872. […] Nietzsche saw this image of modern print culture embodied in modern journalism’s endless pursuit of the news. In the face of the modern media machine, he longed for timelessness, but one not simply stripped of its time and place. Instead, it was an ethos of active resistance to the “idolatrous” need for the new, the latest headline, the latest commentary, the latest feuilleton. It was intended to enlist those few who were not, as he put it in the Basel lectures, “caught up in the dizzying haste of our hurtling era” and dependent on its short-lived pleasures. It was a call for calm readers. [The Hedgehog Review]

Narcissism levels have been increasing among Western youth, and contribute to societal problems such as aggression and violence. The origins of narcissism, however, are not well understood. Here, we report, to our knowledge, the first prospective longitudinal evidence on the origins of narcissism in children. We compared two perspectives: social learning theory (positing that narcissism is cultivated by parental overvaluation) and psychoanalytic theory (positing that narcissism is cultivated by lack of parental warmth). We timed the study in late childhood (ages 7–12), when individual differences in narcissism first emerge. In four 6-mo waves, 565 children and their parents reported child narcissism, child self-esteem, parental overvaluation, and parental warmth. Four-wave cross-lagged panel models were conducted. Results support social learning theory and contradict psychoanalytic theory: Narcissism was predicted by parental overvaluation, not by lack of parental warmth. Thus, children seem to acquire narcissism, in part, by internalizing parents’ inflated views of them (e.g., “I am superior to others” and “I am entitled to privileges”). Attesting to the specificity of this finding, self-esteem was predicted by parental warmth, not by parental overvaluation. [PNAS]
Even Women Who Should Know Better Are Attracted to Narcissists
If a woman overestimates her romantic partner’s commitment, the cost to her fitness—reproduction without an investing partner—can be considerable. Error Management Theory predicts that women have an evolved bias to be skeptical of men’s commitment in a relationship, which reduces the likelihood of making a costly false positive error.

The sexual selection concept arises from the observation that many animals had evolved features whose function is not to help individuals survive, but help them to maximize their reproductive success. This can be realized in two different ways: by making themselves attractive to the opposite sex (intersexual selection, between the sexes); or by intimidating, deterring or defeating same-sex rivals (intrasexual selection, within a given sex). Thus, sexual selection takes two major forms: intersexual selection (also known as 'mate choice' or 'female choice') in which males compete with each other to be chosen by females; and intrasexual selection (also known as 'male–male competition') in which members of the less limited sex (typically males) compete aggressively among themselves for access to the limiting sex. The limiting sex is the sex which has the higher parental investment, which therefore faces the most pressure to make a good mate decision. For intersexual selection to work, one sex must evolve a feature alluring to the opposite sex, sometimes resulting in a "fashion fad" of intense selection in an arbitrary direction. Or, in the second case, while natural selection can help animals develop ways of killing or escaping from other species, intrasexual selection drives the selection of attributes that allow alpha males to dominate their own breeding partners and rivals. [Wikipedia]
Canine teeth, horns, claws, and the sheer size and strength of certain male animals provide strong examples of physical weapons, and aggression is a behavioral weapon among humans and other animals. A peacock’s tail, which is useless and costly to sustain, is the most famous example of an ornament. Showing off and creativity may be the human equivalents of this ornamentation. Certain polygynous species, such as the elephant seal, become weapon specialists, relying primarily on intrasexual combat to achieve reproductive success. Other species, such as the peacock and numerous birds of paradise, specialize in intersexual selection to produce extravagant male ornaments. Humans are versatile animals who rely on a large brain to facilitate amassing and facultatively employing a large repertoire of survival and reproductive strategies, including weapons and ornaments. Even though ancestral men may have used intrasexual combat more than intersexual ornaments in acquiring mates and much human female choice may also have derived from male contests, modern men use both intrasexual and intersexual mating strategies as evidenced by much research showing a clear association between mating motivation and various behaviors that constitute weapons and ornaments in men. Specific weapon-like behaviors under mating investigation include physical or direct aggression in response to provocation, social dominance and status, endorsing warring attitudes, and producing a low voice pitch. The studied ornament-like behaviors include conspicuous material consumption, risk taking, humor, being unique and non-conforming, becoming loss averse, making generous financial donations, and exhibiting heroic altruism, all of which are preferred by women. These studies suggest that, similar to other male animals, men can exhibit weapon-like and ornament-like behaviors, but, unlike many male animals that specialize in either weapons or ornaments nearly to the exclusion of the other, men seem to have developed the versatility to acquire and apply both strategies to facultatively respond to intrasexual and intersexual competition. Men may use weapons and ornaments facultatively as situational responses to intersexual and intrasexual conditions and, over time, may also develop behavioral tendencies in using one strategy more frequently over the other, adding to the vast individual differences along a weapon-ornament dimension.

DNA can’t explain all inherited biological traits, research shows
A group of leading biologists called for a worldwide moratorium on use of a new genome-editing technique that would alter human DNA in a way that can be inherited. The biologists fear that the new technique is so effective and easy to use that some physicians may push ahead before its safety can be assessed. They also want the public to understand the ethical issues surrounding the technique, [which holds the power to repair or enhance any human gene, and] could be used to cure genetic diseases, but also to enhance qualities like beauty or intelligence. [NY Times]
Genome-editing technologies may offer a powerful approach to treat many human diseases, including HIV/AIDS, haemophilia, sickle-cell anaemia and several forms of cancer. All techniques currently in various stages of clinical development focus on modifying the genetic material of somatic cells, such as T cells (a type of white blood cell). These are not designed to affect sperm or eggs. […] The newest addition to the genome-editing arsenal is CRISPR/Cas9, a bacteria-derived system that uses RNA molecules that recognize specific human DNA sequences. The RNAs act as guides, matching the nuclease to corresponding locations in the human genome. [Nature]

New Alzheimer’s treatment fully restores memory function
Recalling one memory actually leads to the forgetting of other competing memories, a new study confirms. It is one of the single most surprising facts about memory, now isolated by neuroscience research. Although many scientists believed the brain must work this way, this is the first time it has been demonstrated. [PsyBlog | Nature]
15 years ago, the neurosciences defined the main function of brains in terms of processing input to compute output: “brain function is ultimately best understood in terms of input/output transformations and how they are produced” wrote Mike Mauk in 2000. Since then, a lot of things have been discovered that make this stimulus-response concept untenable and potentially based largely on laboratory artifacts. For instance, it was discovered that the likely ancestral state of behavioral organization is one of probing the environment with ongoing, variable actions first and evaluating sensory feedback later (i.e., the inverse of stimulus response). […] In humans, functional magnetic resonance imaging (fMRI) studies over the last decade and a half revealed that the human brain is far from passively waiting for stimuli, but rather constantly produces ongoing, variable activity, and just shifts this activity over to other networks when we move from rest to task or switch between tasks. [Björn Brembs]

Japan’s House Foods Group Inc. said it has developed onions that release extremely low amount of tear-inducing compounds. [...] [T]he resulting onions have the added benefit of not leaving a strong smell on the cook’s hands or the breath of those who eat them. [WSJ]
This cure known as “Bald’s eye salve,” a mixture of onion, garlic, leek, wine, cow’s bile and cow’s stomach, actually works for wiping out methicillin-resistant staphylococcus aureus, known as MRSA. MSRA is a bacteria that is resistant to many antibiotics, and can cause anything from skin infections to widespread infection and pneumonia. […] Because cow stomach was part of the MRSA remedy, there have been questions about whether corpse medicine may have actually had some effect on health and whether it actually cured anything. Corpse medicine, or medical cannibalism, is the act of using parts of deceased humans for medicinal reasons. This persists today in such acts as organ transplant and blood transfusions. However, in the past, corpses were used for a wide variety of medical purposes and were thought to be able to cure anything from bleeding to aging to epilepsy. [Bones Don’t Lie]

Anthropodermic bibliopegy is the practice of binding books in human skin. Though extremely uncommon in modern times, the technique dates back to at least the 17th century. The practice is inextricably connected with the practice of tanning human skin, often done in certain circumstances after a corpse has been dissected. Surviving historical examples of this technique include anatomy texts bound with the skin of dissected cadavers, volumes created as a bequest and bound with the skin of the testator, and copies of judicial proceedings bound in the skin of the murderer convicted in those proceedings, such as in the case of John Horwood in 1821 and the Red Barn Murder in 1828. [Wikipedia]
Anthropologists have shown that the practice of cannibalism is very often linked to magic, as the provider of the most potent ingredients to make ‘medicine’ to make a person bullet-proof, able to fly, all-powerful, and many more wondrous things.

Furans are coffee’s dirty little secret. Although we can thank them for the pleasant aroma and delicious flavour of freshly brewed coffee, furans have been labelled as a possible human carcinogen (cause of cancer) in disguise by food safety agencies including the United States Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). Furans enter our food chain through canned, bottled and jarred processed foods, but 85% of furan exposure in adults is from coffee consumption. All these products undergo ultra-high temperature (UHT) treatment and furans are one of the carcinogenic compounds produced. The canned, bottled and jarred foods are sterilized this way to eradicate disease-causing micro-organisms and to increase their shelf-life. Coffee beans are heated to even higher temperatures during roasting. Furans are volatile and not very water-soluble so how you like your coffee, roasted, ground, stored and brewed, will determine how much furan is left in your cup of Joe. […] Arisseto and colleagues (2011) […] found that furan content was higher in Robusta samples. […] Altaki and colleagues (2011) found regular decaffeinated or caffeinated brews made with an espresso machine had higher furan content than a drip coffee maker, and instant coffee brews had relatively low levels whilst coffee capsules contained the most. […] Leaving your cup of coffee to stand at room temperature for 30 minutes before drinking will reduce furan amounts by 25% according to Guenther and colleagues (2010). [United Academics]
Denis Vrain-Lucas was trained as a law clerk, but by 1854 he had begun to forge historical documents, especially letters. Lucas began by using writing material and self-made inks from the appropriate period and forged mainly documents from French authors. He collected historical details from the Imperial library. As his forgeries were more readily accepted, he began to produce letters from historical figures. Over 16 years Vrain-Lucas forged total of 27,000 autographs, letters, and other documents from such luminaries as Mary Magdalene, Cleopatra, Judas Iscariot, Pontius Pilate, Joan of Arc, Cicero and Dante Alighieri - written in contemporary French and on watermarked paper. The most prominent French collectors bought them, helping Lucas accumulate a significant wealth of hundreds of thousands of francs. In 1861 Vrain-Lucas approached French mathematician and collector Michel Chasles and sold him forged letters for Robert Boyle, Isaac Newton and Blaise Pascal. In one of them Pascal supposedly claimed that he had discovered the laws of gravity before Newton. Since this would have meant that a Frenchman would have discovered gravity before an Englishman, Chasles accepted the letter and asked for more. Lucas proceeded to sell him hundreds of letters from historical and biblical figures. In 1867 Chasles approached the French Academy of Science, claiming to have proof that Pascal had discovered gravity before Newton. When he showed them the letters, scholars of the Academy noticed that the handwriting was very different compared to letters that were definitely by Pascal. Chasles defended the letters’ authenticity but was eventually forced to reveal that Vrain-Lucas had sold them to him. […] In February 1870, the Correctional Tribunal of Paris sentenced Vrain-Lucas to two years in prison for forgery. He also had pay a fine for 500 francs and all legal costs. Chasles received no restitution for all the money he had wasted on the Vrain-Lucas forgeries. [Wikipedia]
