"Levi and his co-authors, former Sauder PhD students Qianqian Du and Huasheng Gao, investigated the birth-date effect in a sample of 375 CEOs from S&P 500 companies between 1992 and 2009. "Our study adds to the growing evidence that the way our education system groups students by age impacts their lifelong success," says Prof. Levi. "We could be excluding some of the business world's best talent simply by enrolling them in school too early.""

Project MUSE is a leading provider of digital humanities and social sciences content; since 1995, its electronic journal collections have supported a wide array of research needs at academic, public, special, and school libraries worldwide. MUSE books and journals, from leading university presses and scholarly societies, are fully integrated for search and discovery.

"Our ethos: We help people make sense of current discussions rather than taking them back to school We stand up for scientific inquiry, free from stigma, intimidation, hysteria or censorship We want everyone, whatever their experience, to stand up for evidence in public life"

"My link was shared by Bora Zivkovic, whose network is immense. And in turn, the link was shared by Twitter users in Greece, Germany, Belgium and throughout the United States. In the end, the blogpost wound up with 109 readers on January 22nd - with about 50 via Twitter, 26 via Facebook, and others via LinkedIn and elsewhere. When each person shared the link with her or his network, the momentum is carried forward, pushing out to new networks and new degrees of separation. Social sharing is a bit like the emails you would get forwarded by your relatives (you know, those emails). The deeper you scroll down the thread, the less sender names you recognize. But with Twitter, and using analytics like WordPress or Google, you can actually trace how a little link travels through different social networks, and eventually back to your website. Also, because many people embed a small bio or website link in their Twitter profile, I can quickly see who has retweeted and read my link. I can read their tweets to get an idea of their profession and passions,"

The EconCS Group pursues research, both theoretical and experimental, at the intersection between computer science and economics.

"It seems like his brain isn't working quite properly and according to new findings, it may not be. Researchers have begun to explore the cognitive impairment that men experience before and after interacting with women. A 2009 study demonstrated that after a short interaction with an attractive woman, men experienced a decline in mental performance. A more recent study suggests that this cognitive impairment takes hold even w hen men simply anticipate interacting with a woman who they know very little about. Sanne Nauts ... Daisy Grewal is a researcher at the Stanford School of Medicine, where she investigates how stereotypes affect the careers of women and minority scientists."

Come work with us Interested in working with researchers from different disciplines within the Harvard, MIT and Broad community and an unique opportunity to participate in world-class research to make an impact on human health? Come work with us! We are looking for a computational biologists to handle data from a wide variety of experimental methods, focusing on next-gen sequencing technologies. Keep Reading...  SCDE is live The Stem Cell Discovery Engine (SCDE) is an integrated platform that allows users to consistently describe, share and compare cancer and tissue stem cell data. It is made up of an online database of curated experiments coupled to a customized instance of the Galaxy analysis engine with tools for gene list manipulation and molecular profile comparisons. The SCDE currently contains more than 50 stem cell-related experiments. Each has been manually curated and encoded using the ISA-Tab standard to ensure the quality of the data and its annotation.

"Was die Zellzahl angeht, besteht jeder Mensch zu 90 Prozent aus Mikroben", sagt Dennis Kasper von der Harvard Medical School in Boston. Die Hauptmasse dieser Mitbewohner des menschlichen Körpers lebt im Darm. Sie unterstützen nicht nur die Verdauung, sondern sind für unsere Gesundheit generell unverzichtbar. So wie sie sich speziell an ihren Wirt angepasst haben, hat sich auch unser Organismus an die Mikroben angepasst. Insbesondere hängt die normale Entwicklung des Immunsystems von der Mitwirkung der Darmkeime ab. Das schließen Kasper und seine Kollegen aus ihren Experimenten mit Mäusen, die in keimfreier Umgebung gehalten wurden. In den bakterienfreien Darm neugeborener Mäuse übertrugen die Forscher ein natürliches Gemisch von Darmmikroben, das entweder von gesunden Mäusen oder von gesunden Menschen stammte. In beiden Fällen kam es zum Wachstum von Bakterien in ähnlich hoher Zahl und mit einem ähnlich breiten Artenspektrum. Beide Bakterienpopulationen waren aber aus sehr unterschiedlichen Keimspezies zusammengesetzt, wie DNA-Analysen zeigten. Die Untersuchung von Darmlymphknoten ergab, dass sich bei den Mäusen mit den „menschlichen" Darmkeimen genauso wenige Immunzellen entwickelt hatten wie bei Mäusen, deren Darm völlig keimfrei blieb. „Es schien so, als ob diese Mäuse die Bakterien gar nicht erkennen würden", sagt Hachung Chung, ein Mitglied des Forscherteams"

""We probably have underestimated the role our microbial flora play in modulating disease risk," says Daniel Rader, a heart disease specialist at the University of Pennsylvania School of Medicine. Rader, who was not involved in the study, says that gut bacteria may not be as big a factor in causing heart disease as diabetes or smoking, but could be important in tipping some people toward sickness. Researchers led by Stanley Hazen, a cardiologist at the Cleveland Clinic, didn't start out to study gut bacteria. In fact, says Hazen, he had "no clue - zero," that intestinal microbes were involved in heart disease. "I'd never even considered it or thought of the concept." Hazen and his colleagues compared blood plasma from healthy people to plasma from people who had had heart attacks, strokes or died to see if substances in the blood could predict who is in danger from heart disease. The researchers found 18 small molecules associated with fat buildup in the arteries. One of the best predictors turned out to be a byproduct made when gut bacteria break down a fat called choline (also known as lecithin). The more of this byproduct, called trimethylamine N-oxide or TMAO, a person or mouse has in the blood, the higher the risk of getting heart disease, the researchers found. Gut bacteria are actually middlemen in TMAO production. The microbes convert lecithin to a gas that smells like rotten fish. Then an enzyme in the liver changes the foul-smelling gas to TMAO."

"Our Juliets (as parents longing for grandchildren will recognize with a sigh) may experience the tumult of love for 20 years before they settle down into motherhood. And our Romeos may be poetic lunatics under the influence of Queen Mab until they are well into graduate school. What happens when children reach puberty earlier and adulthood later? The answer is: a good deal of teenage weirdness. Fortunately, developmental psychologists and neuroscientists are starting to explain the foundations of that weirdness.

We're just starting, but we already have some good materials. The Computer Science Portal serves to provide quick access to everything in the Computer Science category.

Tabula will be platform and content agnostic, working with as many brands and versions of tablet computers as possible. Of course, compatibility takes coding hours, so we'll start with one or two platforms and build from there. But let's just say we fully recognize the value of high-end and lower-cost hardware when it comes to solutions to help schools thrive.

"Mäuse mit der Darmflora der Übergewichtigen wurden dick, die anderen blieben hingegen schlank. Als die Forscher nun beide Mäusegruppen gemeinsam hielten, übertrugen sich die schlankmachenden Bakterien auch auf die dicken und ließen sie abmagern. Doch diese Übertragung fand nicht statt, wenn die Tiere fettreich ernährt wurden. Die Ergebnisse der Forscher um Jeffrey Gordon von der Washington University School of Medicine ergänzen kürzlich erschienene Studien, die bereits einen Zusammenhang zwischen den Eigenschaften der Darmflora eines Menschen und dessen Körpergewicht beziehungsweise Stoffwechsel aufgezeigt hatten. Die aktuelle Studie belegt nun allerdings konkret: Eine Neigung zum Übergewicht beziehungsweise Schlanksein hängt direkt mit den Darmbakterien zusammen und lässt sich mit ihnen sogar übertragen. Es zeichnen sich nun außerdem mikrobielle Drahtzieher ab: Bakterien aus der Gruppe der Bacteroides scheinen Schlanke vor übermäßiger Gewichtszunahme zu schützen."
