New MIT report predicts serious future warming
September 30, 2014 07:38 AM - Audrey Resutek | MIT Joint Program on the Science and Policy of Global Change
Global temperature is likely to rise 3.3-5.6 degrees Celsius by the end of this century, unless international climate negotiations in Paris next year are more effective than expected, according to a report released Monday by the MIT Joint Program on the Science and Policy of Global Change. The predicted temperature increase surpasses the threshold identified by the United Nations as necessary to avoid the most serious impacts of climate change, altering precipitation patterns and heightening the pressures of population and economic growth. "Our world is rapidly changing," says John Reilly, co-director of the MIT Joint Program and a coauthor of the report. "We need to understand the nature of the risks we’re facing so we can prepare for them."
A concrete idea: MIT develops better, greener, concrete
September 25, 2014 01:06 PM - David L. Chandler, MIT News Office
Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half - and the result would be a stronger, more durable material. The findings come from the most detailed molecular analysis yet of the complex structure of concrete, which is a mixture of sand, gravel, water, and cement. Cement is made by cooking calcium-rich material, usually limestone, with silica-rich material - typically clay - at temperatures of 1,500 degrees Celsius, yielding a hard mass called "clinker." This is then ground up into a powder. The decarbonation of limestone, and the heating of cement, are responsible for most of the material's greenhouse-gas output.
The Future of Vertical Farming
September 19, 2014 06:15 AM - Allison Winter, ENN
From big company agricultural farming, to communal farming or even personal agronomy, the business of growing crops for an expanding global population will be crucial in the near future. The two most important resources needed to run these farms are one, water, and two, land. But these resources often come at a premium, especially with growing populations and increased food demand. Farmers and researchers have already started leaning towards genetic engineering and industrial processing to help with their crop yields, but a new solution in agribusiness is emerging. Vertical farming.
Northern Lights Dazzle Skies Tonight

If you live in one of the visible areas on this map, you may be in for a treat tonight! According to AccuWeather.com, the solar flares of the Northern Lights are ranked as an X-class tonight, the highest class for a solar flare which may make the Northern Lights display as far south as Maryland on the East Coast, and as far down as Nebraska, further west.
Disc or Download: A Virtual Energy-Savings Debate
September 11, 2014 11:20 AM - Winfield Winter, ENN
One of the best ways to spark an energy revolution is through the younger generation — and nothing quite speaks their language like video games. But this issue has less to do with the content of these addictive games and more with how the younger generation consumes them. Fantasy and adventure, sci-fi and first-person shooters, strategy and racing — video games today comes in all types of genres with thousands of add-ons and customizable features to make each story a virtual reality. And with all of these choices comes two more: buy a copy of the video game on a disc or download the video game straight from the console?
How is a warming climate impacting coral reefs?
September 10, 2014 07:34 AM - Roger Greenway, ENN
How is a warming climate impacting life in the oceans? Fish can move to cooler areas, but coral reefs are anchored in place. Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. Researchers indicate that the warmer water temperatures are stressing corals and increasing the number of bleaching events, where corals become white resulting from a loss of their symbiotic algae. The corals can starve to death if the condition is prolonged.
How Pollutant Risk is Affected by Different Insect Stages
September 5, 2014 11:34 AM - Editor, ENN
The food chain is a hierarchical series of organisms that are interrelated in their feeding habits. The chain starts when the smallest being like an insect is fed upon a larger prey species, which in turn feeds an even larger species. So if a species among the lower ranks of the chain has accumulated toxins such as pesticides or other organic chemicals, there is potential for these toxic substances to affect the species that prey upon them. This is the subject of new research conducted by the US Geological survey that found when fish feed on insects and when other wildlife species feed on fish, harmful contaminants are transferred up the line.
More benefits of green neighborhoods
September 4, 2014 02:32 PM - Oregon State Universtity
Mothers who live in neighborhoods with plenty of grass, trees or other green vegetation are more likely to deliver at full term and their babies are born at higher weights, compared to mothers who live in urban areas that aren’t as green, a new study shows. The findings held up even when results were adjusted for factors such as neighborhood income, exposure to air pollution, noise, and neighborhood walkability, according to researchers at Oregon State University and the University of British Columbia.
Mystery Behind Slithering Rocks of Death Valley Revealed
August 28, 2014 09:38 AM - Allison Winter, ENN
In California's Death Valley, a geological phenomenon exists. Sailing stones, or moving rocks can be observed on the valley floor inscribing long trails on the ground without human or animal intervention. For over 60 years of observations, no one has been able to uncover the mystery of what is actually pushing these stones across the sand. That is, until now.
Yawn Contagion in Wolves
August 27, 2014 04:15 PM - Editor, ENN
A yawn is defined as a reflex act of opening one's mouth and inhaling deeply. We yawn most often when we are tired or when we're bored. But we also always yawn when we see someone else doing it. Why? People say we can't help it - it's contagious! But what really triggers this involuntary tendency? According to studies, yawning when others do is a sign of empathy and a form of social bonding. And believe it or not, we're not the only species to exhibit these contagious behaviors. A new study published today in the journal PLOS ONE shows that wolves may also be susceptible to yawn contagion.
