Game of Farmers: Agriculture is coming
by gdw in FictionalFieldwork
Gron gazed across the plain from inside a tuft of long grass. There. Just in front of the far hillock. Gazelles. Meals on legs. He vaguely remembered mother carrying him through cooler forests when he was not yet old enough to walk. He had never understood why they had left. But he had learned, had […]... Read more »

The Mesh of Civilizations in Cyberspace
by Jalees Rehman in The Next Regeneration
A team of researchers from Stanford University, Cornell University and Yahoo recently decided to evaluate the "connectedness" of the hypothesized Huntington civilizations in cyberspace and published their results in the article "The Mesh of Civilizations in the Global Network of Digital Communication".
The researchers examined Twitter users and the exchange of emails between Yahoo-Mail users in 90 countries with a minimum population of five million. In total, they analyzed........ Read more »

The Dire State of Science in the Muslim World
by Jalees Rehman in The Next Regeneration
Universities and the scientific infrastructures in Muslim-majority countries need to undergo radical reforms if they want to avoid falling by the wayside in a world characterized by major scientific and technological innovations. This is the conclusion reached by Nidhal Guessoum and Athar Osama in their recent commentary "Institutions: Revive universities of the Muslim world", published in the scientific journal Nature. The physics and astronomy professor Guessoum (American University ........ Read more »

The Long Shadow of Nazi Indoctrination: Persistence of Anti-Semitism in Germany
by Jalees Rehman in The Next Regeneration
Voigtländer and Voth examined the results of the large General Social Survey for Germany (ALLBUS) in which several thousand Germans were asked about their values and beliefs. The survey took place in 1996 and 2006, and the researchers combined the results of both surveys with a total of 5,300 participants from 264 German towns and cities. The researchers were specifically interested in anti-Semitic attitudes and focused on three survey questions specifically related to anti-Semitism. Survey........ Read more »

Typical Dreams: A Comparison of Dreams Across Cultures
by Jalees Rehman in The Next Regeneration
Have you ever wondered how the content of your dreams differs from that of your friends? How about the dreams of people raised in different countries and cultures? It is not always easy to compare dreams of distinct individuals because the content of dreams depends on our personal experiences. This is why dream researchers have developed standardized dream questionnaires in which common thematic elements are grouped together. These questionnaires can be translated into various languages and used........ Read more »

Climate Change: Heatwaves and Poverty in Pakistan
by Jalees Rehman in The Next Regeneration
In the summer of 2010, over 20 million people were affected by the summer floods in Pakistan. Millions lost access to shelter and clean water, and became dependent on aid in the form of food, drinking water, tents, clothes and medical supplies in order to survive this humanitarian disaster. It is estimated that at least $1.5 billion to $2 billion were provided as aid by governments, NGOs, charity organizations and private individuals from all around the world, and helped contain the devastating ........

Hard times, tough gods
Almost all cultures have some kind of supernatural beliefs. But it may surprise you to know that belief in moralising supernatural beings, who care about whether mortals do good or bad, are far from universal. That’s fascinating, and it begs the question: “why?”. Why do some cultures bother to believe spirits who watch over us [Read More...]

A Parched Future: Global Land and Water Grabbing
by Jalees Rehman in Fragments of Truth
Land grabbing refers to the large-scale acquisition of comparatively inexpensive agricultural land in foreign countries by foreign governments or corporations. In most cases, the acquired land is located in under-developed countries in Africa, Asia or South America, while the grabbers are investment funds based in Europe, North America and the Middle East. The acquisition can take the form of an outright purchase or a long-term-lease, ranging from 25 to 99 years, that gives the grabbing entity e........ Read more »

The Olympic Effect: Will Sochi Really Benefit?
by Nura Rutten in United Academics
Major sports events seem to be one of the best city marketing strategies. The connotation of heroic achievements, camaraderie and excitement is the ultimate promotion for any city in the world.Several studies have examined the influence on a city of hosting a mega-event. First, a research from 2011 published in The Economic Journal shows that after the event, trade is over 20% higher for host countries.... Read more »

Heat drives Pakistani migration

The Aspens that were left behind
by Jes in Biogeography Bits
When climates change, species move. It’s a fact of life on Earth and probably has been for the past 542 million years, even when species don’t have legs or wings or fins to get them from place to place.
Quaking aspen is one example of a seemingly stationary species that has managed in just the past 20,000 years to expand into the largest range of any native North American tree.... Read more »

Biological Beta Testing: Altitudinal Edition
by Melissa Chernick in Science Storiented
Spatial patterns in biodiversity have always been a popular topic in ecology, and understanding these patterns helps us to address the looming threats to biodiversity.Did you notice how I made the word ‘patterns’ plural? There isn’t a whole separate field of biogeography for nothin’. Biological diversity is difficult (some say impossible) to measure using a single metric. How do you count things? Simply by the number of species? How about rare versus common species? What about species t........ Read more »
