People with a strong moral identity are measurably inspired to do good after being exposed to media stories about uncommon acts of human goodness, according to research at the University of British Columbia's Sauder School of Business.

Back in 2009 Mayor Bloomberg prohibited vehicle traffic on Broadway between 42nd Street and 47th Street in Times Square to create a pedestrian plaza (video here). Now, the city's most recent Community Air Survey found that, "After the conversion to a pedestrian plaza, NO pollution levels in Times Square went down by 63 percent while, NO2 levels went down by 41 percent." Unlike N2O, which makes you laugh at Phish shows, NO2, or nitrogen dioxide, destroys your lungs and may cause Sudden Infant Death Syndrome. Nitric oxide (NO) isn't good for you either.

On the other hand, humanity's malignant effect on the environment has accelerated the rate of extinction for plants and animals, which now reaches perhaps 50,000 species a year. But even here there was some good news. We reversed our first man-made global atmospheric crisis by banning chlorofluorocarbons -- by 2015, the Antarctic ozone hole will have shrunk by nearly 400,000 square miles. Stopping climate change has been a slower process. Nonetheless, in 2008, the G-8 did commit to halving carbon emissions by 2050. And a range of technological advances -- from hydrogen fuel cells to compact fluorescent bulbs -- suggests that a low-carbon future need not require surrendering a high quality of life. Technology has done more than improve energy efficiency. Today, there are more than 4 billion mobile-phone subscribers, compared with only 750 million at the decade's start. Cell phones are being used to provide financial services in the Philippines, monitor real-time commodity futures prices in Vietnam, and teach literacy in Niger. And streaming video means that fans can watch cricket even in benighted countries that don't broadcast it -- or upload citizen reports from security crackdowns in Tehran. Perhaps technology also helps account for the striking disconnect between the reality of worldwide progress and the perception of global decline. We're more able than ever to witness the tragedy of millions of our fellow humans on television or online. And, rightly so, we're more outraged than ever that suffering continues in a world of such technological wonder and economic plenty. Nonetheless, if you had to choose a decade in history in which to be alive, the first of the 21st century would undoubtedly be it. More people lived lives of greater freedom, security, longevity, and wealth than ever before. And now, billions of them can tweet the good news. Bring on the 'Teenies.

"A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales."

"You hear that it's good to recycle everything," Mr. Herscher said, "and then you hear it takes more energy to recycle paper than it does to cut it down. It's really hard to know what the right thing to do is. This is a way to express my own frustrations."

Web-connected devices, not just mobile phones and 3G tablets but everything from home electronics to consumer packaged goods instrumented to transmit data to the Web, have become a part of every major speech here at the wireless industry's giant conference in Orlando, CTIA. "All devices that can benefit from connectivity will be connected," Hans Vestberg, CEO of Ericsson, said in a keynote, predicting that the world's nearly 5 billion mobile phone subscribers today will be surpassed by 50 billion connected non-phone devices in 10 years.

Germany is determined to show the world how abandoning nuclear energy can be done.

Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.

How many times do we hear that some scientific view is "only theory" or that it is "not proven"? The hidden implication is that if we have not "proven" the case, then we do not know anything for certain about it, and any idea is as good as any other. A recent and vivid example of this problem is the ongoing argument in the popular media about global warming. Do we need to be absolutely certain before we take action?

The time it takes for new products to come to market is getting ever shorter. As a consequence, goods are being produced using manufacturing facilities and IT systems that were designed with completely different models in mind. Fraunhofer developers want to make factories smarter so they can react to changes of their own accord.

In this July 15, 2008 file photo, a sign advocating buying fresh and local in the Shenandoah Valley is tacked on a bulletin board at the Shenandoah Valley Produce auction in Dayton, Va. A heightened consumer interest in produce grown nearby, which many assume to mean fresher food, fewer chemicals, and grown smaller farms, has led to popular use of the word on displays and menus. While good for many farmers, the trend can be misleading for consumers, as there is no one or regulated meaning for "local".

In an unprecedented collaborative analysis published in the journal PLoS Biology, scientists from 49 nations demonstrated that the ability of reef fish systems to produce goods and services to humanity increases rapidly with the number of species. However, growing human populations hamper the ability of reefs to function normally, and counterintuitively, the most diverse reef fish systems suffer the greatest impairments from stressors triggered by human populations. The study documented that the extent of this distress is widespread and likely to worsen because 75% of the world's reefs are near human settlements and because around 82% of the tropical countries with coral reefs could double their human populations within the next 50 to 100 years.

A new analysis, published this week and conducted by a team of scientists led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, shows stricter vehicle emission standards would yield major health, agricultural, and climate benefits.

Flat out wrong. That's what a team of Duke researchers has discovered, much to its surprise, about a long-accepted explanation of how nuclei collide to produce charged particles for electricity - a process receiving intense interest lately from scientists, entrepreneurs and policy makers in the wake of Japan's nuclear crisis.

Do you have an embarrassing moment in your past? Did it turn out to be newsworthy? There is a good chance it made it to the Internet and now is forever searchable by Google and the other search engines. Google is being hit with a "Right To Forget" lawsuit in Spain as the country's Data Protection Agency has ordered the Web giant to take down search links on 90 people. According to The Associated Press, Google is fighting five of those lawsuits in Spain's National Court and in January refused Spain's request on all 90 of the claims.

Don't judge food by its organic label because "organic" doesn't necessarily mean good it's for you. Yet a new study by Jenny Wan-Chen Lee, a graduate student in Cornell's Dyson School of Applied Economics and Management, finds that consumers persist in believing that foods labeled "organic" are healthier and lower in fat.

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.

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.

People who look at the past through rose-tinted glasses are happier than those who focus on negative past experiences and regrets, according to a new study published in the journal Personality and Individual Differences. The study helps explain why personality has such a strong influence on a person's happiness. The findings suggest that persons with certain personality traits are happier than others because of the way they think about their past, present and future.

"Celebrating" the killing of any member of our species--for example, by chanting USA! USA! and singing The Star Spangled Banner outside the White House or jubilantly demonstrating in the streets--is a violation of human dignity. Regardless of the perceived degree of "good" or "evil" in any of us, we are all, each of us, human. To celebrate the killing of a life, any life, is a failure to honor life's inherent sanctity.
