Jane Poynter and seven compatriots agreed to spend two years sealed inside a 3-acre terrarium in the Sonoran Desert. Their mission back in the 1990s: To see whether humans might someday be able to create self-sustaining colonies in outer space.

Evidence supporting the link between savings and college success is growing. Three studies out of the Center for Social Development (CSD) at the Brown School at Washington University in St. Louis offer a connection between assets and college enrollment and completion.

On April 26, 1986, history's greatest nuclear accident took place northwest of the Ukrainian city of Chernobyl. Despite the scale of the disaster, 25 years later, we still do not know its real effects. An international team of investigators has shown for the first time that the colour of birds' plumage may make them more vulnerable to radioactivity.

It's an unfamiliar neighborhood and you find yourself in the middle of a bunch of streets and buildings you've never seen before. Giving the environment a quick once-over, you make a snap decision about whether you're safe or not. And chances are, that first 'gut' call is the right one, say Binghamton University researchers Dan O'Brien and David Sloan Wilson in an article published in the current issue of Journal of Personality and Social Psychology.

Having power over others and having choices in your own life share a critical foundation: control, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The paper finds that people are willing to trade one source of control for the other. For example, if people lack power, they clamor for choice, and if they have an abundance of choice they don't strive as much for power.

Authorities in Yangon have banned plastic bags, state media said Tuesday, in an attempt to stop non-degradable waste polluting Myanmar's main city.

The feeling of security and the reality of security don't always match, says computer-security expert Bruce Schneier. He explains why we spend billions addressing news story risks, like the "security theater" now playing at your local airport, while neglecting more probable risks - and how we can break this pattern.

The sign was a digital billboard, a new breed of outdoor advertising that is growing in both the region and the nation. The problem for Young, a Philadelphia architect, is that they're energy guzzlers, compared with other signage. In a recent report, he found that the largest of them can use 30 times what a typical household consumes. The report - funded by an independent grant but done under the auspices of an advocacy group that opposes the signs - concludes that as Philadelphia strives to become the nation's greenest city, a proliferation of digital signs might not be sending the right message.

Precipitation and runoff in California's major river basin will not fall dramatically with climate change, according to a new federal study that shows rising temperatures will have an uneven effect on the West's water supplies.

Zooniverse volunteers, who call themselves "Zooites," are working on a project called Galaxy Zoo, classifying distant galaxies imaged by NASA's Hubble Space Telescope. "Not only are people better than computers at detecting the subtleties that differentiate galaxies, they can do things computers can't do, like spot things that just look interesting," explains Zooniverse director Chris Lintott, an astronomer at the University of Oxford.

The world on Tuesday marks a quarter century since the world's worst nuclear disaster at Chernobyl in Ukraine, haunted by fears over the safety of atomic energy after the Japan earthquake

Researched and designed by technologist Michell Zappa, Envisioning Technology is a speculative and subjective overview of potential future technologies. Based on personal research and observations, this map is intended to facilitate predictions of where the technium is going, as well as provoke thought and stimulate debate. Due to the intrinsic difficulty of speculation, the visualization is not to be interpreted as a roadmap, but rather as a point of reference for those investigating (or designing) the future of technology. Each hub represents an important area of development to which actual technologies (shown as nodes) belong. The center of the map marks where we are today, and the further out points indicate how far into the future each technology is predicted to become mainstream. The visualization also attempts to distinguish the predicted importance of each area, shown by the relative size of the nodes

In November 2010 the World Economic Forum gathered in Dubai to discuss issues on the global agenda. Before the forum, the 700 members of each of the 72 Global Agenda Councils were asked which other councils they would benefit from interacting with. This data was then released to the public as part of a visualization challenge organized by visualizing.org. Shown here is one of the honorable mentions, an interactive visualization created by Daniel McLaren that shows a map of the strongest collective responses between the councils. It uses the analogy of energy, as described by McLaren: "Starting at the selected node, energy travels outward and is divided among each connection and dissipates when crossing weak connections." Not all responses are displayed because the data has been filtered to show only the strongest relationships.

It's not like open field farming. OK, it is a little bit. Marcin Jakubowski, of Open Source Ecology, has taken it upon himself to release the blueprints for 50 farm machines in open source. According to his TED page, this is one element in a more ambitious project. "Using wikis and digital fabrication tools, TED Fellow Marcin Jakubowski is open-sourcing the blueprints for 50 farm machines, allowing anyone to build their own tractor or harvester from scratch. And that's only the first step in a project to write an instruction set for an entire self-sustaining village."

In a paper published in Proceedings of the National Academy of Sciences, a group of researchers and scientists show that the gains that have been made in stabilizing CO2 emissions in developed or "rich" countries since the signing of the Kyoto agreement, have been neutralized by the increase in CO2 emissions from developing nations as they produce goods for trade, primarily to developed countries. Because of this disparity, many groups are calling for a change to the Kyoto agreement practice of only counting CO2 emissions that are produced in-country, rather than the CO2 footprint of those products that are consumed.

The leading international organizations working to protect and manage the world's forests are calling for governments across the globe to increase communities' role in forest management. Doing so could contribute to lifting close to a billion people out of poverty, as well as improve the health and vitality of forests.

The ants may go marching one by one, but they end up forming a superstructure of thousands -- and together they can form a raft that stretches the boundaries of the laws of physics, according to new research released today.

Amphibian declines around the world have forced many species to the brink of extinction, are much more complex than realized and have multiple causes that are still not fully understood, researchers conclude in a new report.

Britain has brought online a new desalination plant near London capable of providing the city with 150 million gallons (568 million litres) of water per day, should the need arise. At a cost of £270 ($445) million, and built over the past four years, the plant uses reverse osmosis to remove salt from the brackish water pumped in from the Thames Estuary, which it then pumps into local reservoirs, thus staving off the threat of drought.

Although the dune ecosystem is unusual, fragile and is protected by the "habitats" directive of the network Natura 2000, its conservation is very vulnerable to the proliferation of car parks, nearby buildings and inadequate boardwalks installed for protection or beach access.
