A new study published last month in Nature Journal suggests that humans are naturally good. This study adds to the mounting evidence against the popular misconception that corruption is a trait of human nature.

A century ago, industrialists like Andrew Carnegie believed that Darwin’s theories justified an economy of vicious competition and inequality. They left us with an ideological legacy that says the corporate economy, in which wealth concentrates in the hands of a few, produces the best for humanity. This was always a distortion of Darwin’s ideas. His 1871 book The Descent of Man argued that the human species had succeeded because of traits like sharing and compassion.

IN THE SUMMER of 1995, a young graduate student in anthropology at UCLA named Joe Henrich traveled to Peru to carry out some fieldwork among the Machiguenga, an indigenous people who live north of Machu Picchu in the Amazon basin. The Machiguenga had traditionally been horticulturalists who lived in single-family, thatch-roofed houses in small hamlets composed of clusters of extended families. For sustenance, they relied on local game and produce from small-scale farming. They shared with their kin but rarely traded with outside groups.

Information and communication technology has enabled us to solve complex problems in collaboration across the world. Everything from wiki-based platforms to open software development all the way to the experiments in CERN has benefited from advances in ICT. Not only have unprecedented forms of synergy emerged, but also inevitable clashes of opinions between large numbers of individuals.

Many citizens do not want nuclear power. They know it is both far too dangerous and far too expensive. UK governments have largely supported nuclear power as well as nuclear weapons. Many citizens do not want nuclear weapons because they know they are insanely dangerous, and they want to live without the constant threat of sudden and complete annihilation hanging over them and their children.

When Rudy Giuliani ran for mayor of New York City in 1993, he campaigned on a platform of bringing down crime and making the city safe again. It was a comfortable position for a former federal prosecutor with a tough-guy image, but it was more than mere posturing. Since 1960, rape rates had nearly quadrupled, murder had quintupled, and robbery had grown fourteenfold. New Yorkers felt like they lived in a city under siege.

Nearly every coral reef could be dying by 2100 if current carbon dioxide emission trends continue, according to a new review of major climate models from around the world. The only way to maintain the current chemical environment in which reefs now live, the study suggests, would be to deeply cut emissions as soon as possible. It may even become necessary to actively remove carbon dioxide from the atmosphere, say with massive tree-planting efforts or machines.

Noam Chomsky turns eighty-four today, more than a half century after he exploded onto the scene of linguistics, in in the late nineteen-fifties, as a young professor at M.I.T. His career began perhaps most notably with a book review that helped launch an entire field of linguistics (known as generative grammar) and laid waste to another (the behaviorist view of B. F. Skinner that then dominated psychology). From that moment forward, linguistics truly has never been the same.

On Fukushima Beach is an hour long brilliantly constructed documentary that uses a montage of mainstream and Internet media clips to unpack the Fukushima disaster. In addition to providing a painless scientific overview of radiation health issues, it outlines the ongoing radiation risks faced by all residents of the northern hemisphere.

If one were to rank a list of civilization's greatest and most elusive intellectual challenges, the problem of "decoding" ourselves -- understanding the inner workings of our minds and our brains, and how the architecture of these elements is encoded in our genome -- would surely be at the top. Yet the diverse fields that took on this challenge, from philosophy and psychology to computer science and neuroscience, have been fraught with disagreement about the right approach.
