"Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems."

"Our results indicate that communities where species are evenly and distantly related to one another are more stable compared to communities where phylogenetic relationships are more clumped. This result could be explained by a phylogenetic sampling effect, where some lineages show greater stability in productivity compared to other lineages, and greater evolutionary distances reduce the chance of sampling only unstable groups. However, we failed to find evidence for similar stabilities among closely related species. Alternatively, we found evidence that plot biomass variance declined with increasing phylogenetic distances, and greater evolutionary distances may represent species that are ecologically different (phylogenetic complementarity). Accounting for evolutionary relationships can reveal how diversity in form and function may affect stability."

Recent formulations of sexual selection theory emphasise how mate choice can be affected by environmental factors, such as predation risk and resource quality. Women vary greatly in the extent to which they prefer male masculinity and this variation is hypothesised to reflect differences in how women resolve the trade-off between the costs (e.g., low investment) and benefits (e.g., healthy offspring) associated with choosing a masculine partner. A strong prediction of this trade-off theory is that women's masculinity preferences will be stronger in cultures where poor health is particularly harmful to survival. We investigated the relationship between women's preferences for male facial masculinity and a health index derived from World Health Organization statistics for mortality rates, life expectancies, and the impact of communicable disease. Across 30 countries, masculinity preference increased as health decreased. This relationship was independent of cross-cultural differences in wealth or women's mating strategies. These findings show non-arbitrary cross-cultural differences in facial attractiveness judgments and demonstrate the utility of trade-off theory for investigating cross-cultural variation in women's mate preferences.

"These findings clearly state that there is a relationship between summer suicide rates and biochemical (e.g., plasma L-TRP and melatonin levels, [3H]paroxetine binding to blood platelets), metabolic (serum total cholesterol, calcium and magnesium concentrations), and immune (number of peripheral blood lymphocytes and serum sIL-2R) variables.[18] Another study focused on the association between depression, suicide, and the amount of polyunsaturated fatty acids (PUFA). They state that "depression is accompanied by a depletion of n-3 poly-unsaturated fatty acids".[22] Their methodology involved taking periodic blood samples-every month for one year-of healthy volunteers, allowing them to analyze the "PUFA composition in serum phospholipids and [relating] those data to the annual variation in the mean weekly number of suicides". They used an analysis of variance (ANOVA) to document their results, finding that PUFA like arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid all occurred at significantly lower rates in winter than in summer months. The association between depression, suicide, and PUFA rates is indicative of there being a biological factor in seasonal effects on suicide rates"

UrtheCast (pronounced "EarthCast") is a company created around a unique vision: to provide the world's first ever, live HD video feed of Earth from space. Working in an exclusive relationship with world-famous Russian Aerospace giant RSC Energia, UrtheCast is building, launching, installing, and operating two cameras on the Russian module of the International Space Station. Starting in mid-2012, video data of the Earth collected by our cameras will be down-linked to ground stations around the planet and then displayed in near real time on the UrtheCast web platform or distributed directly to our exclusive partners and customers.

The relationship between power, authority, and information since the dawn of the first major information-technology boom How people react to information consumption, according to cognitive science and neuroscience findings How the new, information-abundant society is suffering consequences from poor information consumption habits

"Hudnall: I really do believe that repression makes you sick. I'm big believer of what is coming out in the neuroscience and therapy community. Brene Brown, who is a shame and guilt expert, said it best: "We have an epidemic of shame in this country." If you keep things inside and have no one to talk to - and this is not crystals and patchouli - you will get sick, you will be miserable, you will ruin your relationships, and you will be unhappy. I know people whose lives were ruined by silence. Especially women. The one thing that has really opened my eyes while teaching is just what we do to our women. Only my women students have said to me, "I don't know if I have anything worth saying." It smacks me in the face every day. We are really fucking up our women"

"More than 35 years ago, Matthieu Ricard left a promising career in cellular genetics to study Buddhism in the Himalayas. After earning a doctorate in biology from the prestigious Pasteur Institute in France, Ricard left Paris and moved to Darjeeling, India to study with a great Tibetan master. Today, Ricard draws upon his recent writings, research into brain plasticity and cognitive neuropsychology, and his work with neuroscientists and Buddhist practitioners at the Mind and Life Institute (co-founded by the Dalai Lama), while examining the interconnecting relationship between meditation, brain circuitry, and emotional balance."

A new study in The Lancet rates the harmfulness of 20 psychoactive drugs according to 16 criteria and finds that alcohol comes out on top. Although that conclusion is generating headlines, it is not at all surprising, since alcohol is, by several important measures (including acute toxicity, impairment of driving ability, and the long-term health effects of heavy use), the most dangerous widely used intoxicant, and its abuse is also associated with violence, family breakdown, and social estrangement. A group of British drug experts gathered by the Independent Scientific Committee on Drugs (ISCD) rated alcohol higher than most or all of the other drugs for health damage, mortality, impairment of mental functioning, accidental injury, economic cost, loss of relationships, and negative impact on community. Over all, alcohol rated 72 points on a 100-point scale, compared to 55 for heroin, 54 for crack cocaine, and 33 for methamphetamine. Cannabis got a middling score of 20, while MDMA (Ecstasy), LSD, and psilocybin mushrooms were at the low end, with ratings of 9, 7, and 6, respectively.

Dogs Decoded reveals the science behind the remarkable bond between humans and their dogs and investigates new discoveries in genetics that are illuminating the origin of dogs - with surprising implications for the evolution of human culture. Other research is proving what dog lovers have suspected all along: Dogs have an uncanny ability to read and respond to human emotions. Humans, in turn, respond to dogs with the same hormone responsible for bonding mothers to their babies. How did this incredible relationship between humans and dogs come to be? And how can dogs, so closely related to fearsome wild wolves, behave so differently?

Science is becoming increasingly interested in the relationship between sound and the brain. An expert explains

David Baum, University of Wisconsin, says: "All agree that eukaryotes arose from a symbiotic relationship between two cell types: bacteria that became mitochondria and a host cell, archaea, or a close relative of archaea, that became the cytoplasm and nucleus. This symbiosis explains the origin of mitochondria, but what about other eukaryotic structures, most notably the nucleus?" The Baums' inside-out theory provides a gradual path by which eukaryotic cells could have evolved. The first stage began with a bacterial cell whose outer membrane forms protrusions, which the Baums call 'blebs', that reached out from the cell. These protrusions trapped free-living mitochondria-like bacteria between them. Using the energy gained from being in close contact with bacteria (and using bacterial-derived lipids), cells were able to get bigger and expand the size of their blebs. The sides of the blebs formed the endoplasmic reticulum and their inner surfaces formed the outer membrane of the nucleus, with the original outer membrane of the archaeon becoming what we now call the inner nuclear membrane. Finally, the fusion of blebs with one another led to the formation of the plasma membrane. The result was the eukaryotic cell as we now know it. This inside-out theory is explained in more detail using a diagram in the research article (see notes to editors).
