Taming the Butterfly

Scientists of earth, sea and sky, scholars of law, politics and philosophy: In three intense days cloistered behind Chicheley Hall's old brick walls, four dozen thinkers pondered the planet's fate as it grows warmer, weighed the idea of reflecting the sun to cool the atmosphere and debated the question of who would make the decision to interfere with nature to try to save the planet. The unknown risks of "geoengineering" - in this case, tweaking Earth's climate by dimming the skies - left many uneasy. "If we could experiment with the atmosphere and literally play God, it's very tempting to a scientist," said Kenyan earth scientist Richard Odingo. "But I worry."

US President Barack Obama said Saturday that a transition to cleaner energy will help create more American jobs as he promoted his new initiative designed to reduce US energy imports by a third.

Mangroves, which have declined by up to half over the last 50 years, are an important bulkhead against climate change, a study released on Sunday has shown for the first time.

As Pennsylvania streams go, Conewago Creek in Dauphin, Lebanon and Lancaster counties is really nothing special. But remember the name, because it could hold the key to cleaning up the Chesapeake Bay.

Imagine a cell phone battery that charges with every step you take or a spacesuit that uses astronauts' expended energy to run the suit's electronics. A team of college students conducting NASA research on this innovative use of nanotechnology took their research to new heights. The team, comprising Hannah Clevenson, Olivia Lenz and Tanya Miracle, flew an experiment related to their nanotechnology research on a NASA reduced-gravity flight.

The effects of a major natural disaster can linger and cause heart attacks and other health woes for years, according to a study released Sunday of New Orleans residents after Hurricane Katrina.

Containers made from plastics are used in most traditional greenhouse operations. While plastic containers are practical, strong, and can be formed to any size, shape, or color, the extensive use of these petroleum-based containers creates significant waste disposal problems for the greenhouse industry and consumers. One example: a 2008 report found that a typical greenhouse operation in California discards over 3560 pounds of plastic trays, flats, and containers annually.

Nearly 3 billion pounds of chicken feathers are plucked each year in the United States -- and most end up in the trash. Now, a new method of processing those feathers could create better types of environmentally-friendly plastics.

A new study from the University of Reading highlights how climate change is having a detrimental effect on an endangered tropical bird population.

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center.

The double-digit growth of social networks in the U.S. are on track to reach their peak, according to a new report from eMarketer. eMarkter estimates nearly 150 million Internet users will be active on social networks at least monthly this year, bringing the reach of such sites to 63.7 percent of the online population. By 2013, 164.2 million Americans will use social networks, or 67% of internet users.

If you thought 2010 was disruptive, wait until 2011. This year we saw major game-changers emerge -- the iPad, a flurry of mobile apps, the rise of social commerce, C-Suite fixation on enterprise social-media -- and more. This coming year we'll see even more dramatic change. Keep your eyes on the following

Parallels to our information overload problems in past times. Henry Jenkins is a leading scholar in comparative media studies who currently teaches at USC.

A new intelligence test, which can be taken by any living creature is being developed that will enable comparison of intellect between humans and animals.

"You need to engage the ethical question all along the way"

Since 2010, insurance companies had been turned essentially into public utilities with the feds setting strict minimum benefits requirements. The health reform bill also limited the administrative costs of insurers, which has ended up basically guaranteeing their profits. With competition all but outlawed, the increasingly consolidated insurance industry has had very little incentive to pay for new treatment regimens outside those specified by government standard-setting agencies. Federal government health agencies have been reluctant to authorize newer treatments because they often lead to higher insurance premiums that then must be subsidized by higher taxes. The seen aspect of health care reform is that it has had some success in providing more Americans with access to vintage 2010 medical therapies. The unseen aspect is that more people are suffering from and dying of diseases that might well have been cured had the Obama version of health care reform never been enacted. As a result of health care reform, Americans forfeited 2020 medicine in favor of more equal access to 2010 treatments.

While most people know that the shortest distance between two points is a straight line, this concept is proving even truer in the world of stock trading. In a world where buying low and selling high means all the difference, racing the speed of light between to different financial markets can mean greater profit.

What could health and health care in the US look like in 2020? 

A sleepy New Jersey town has popped onto people's radar screens because it has the oldest running nuclear power plant in the United States -- and, some say, the most dangerous.

During the last quarter-century, average wind speeds have increased over the world's oceans, as have wave heights, generating rougher seas, researchers reported in a study published online Thursday.
