A two-year energy audit of Hamilton schools has identified energy conservation measures that could reduce their energy costs by almost $2.4 million annually. The audit was conducted by engineering faculty and students at McMaster University.

David Keith is Gordon McKay Professor of Applied Physics at Harvard's School of Engineering and Applied Sciences, and Professor of Public Policy at Harvard Kennedy School. The award-winning scientist, who was named one of TIME magazine's Heroes of the Environment in 2009, has worked near the interface of climate science, energy technology, and public policy for twenty years. He divides his time between Boston and Calgary, where he serves as president of Carbon Engineering-a start-up company developing industrial-scale technologies for capture of CO2 from ambient air. Here, Keith answers questions about his research and ideas for reducing climate change using innovative and sometimes controversial methods.

The current focus on assessment means the public debate is overlooking how schools are engaging young people and preparing them for the future, according to Lyn Yates, Professor of Curriculum in the University of Melbourne's Graduate School of Education.

A survey by the National Association of Realtors conducted in March 2011 revealed that 62 percent of people ages 18-29 said they would prefer to live in a communities with a mix of single family homes, condos and apartments, nearby retail shops, restaurants, cafes and bars, as well as workplaces, libraries, and schools served by public transportation.  A separate 2011 Urban Land Institute survey found that nearly two-thirds of 18 to 32-year-olds polled preferred to live in walkable communities. Younger Americans are also using technology to substitute for driving, connecting with friends and family online, substituting Facebook, Twitter, Skype, or FaceTime interactions for in-person visits and using online shopping and e-commerce in place of driving to and from grocery and retail stores, the report notes. For generations of Americans, car ownership was an almost mandatory rite of passage-a symbol of freedom and independence. For more and more young people today, a car is a burden they no longer wish to carry. 

The incidence of type 2 diabetes and hypertension increases with cumulative levels of exposure to nitrogen oxides, according to a new study led by researchers from the Slone Epidemiology Center (SEC) at Boston University. The study, which appears online in the journal Circulation, was led by Patricia Coogan, D.Sc., associate professor of epidemiology at the Boston University School of Public Health and the SEC.

A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems.

Climate scientists have told city planners that based on current trends, Chicago will feel more like Baton Rouge than a Northern metropolis before the end of this century. So, Chicago is getting ready for a wetter, steamier future. Public alleyways are being repaved with materials that are permeable to water. The white oak, the state tree of Illinois, has been banned from city planting lists, and swamp oaks and sweet gum trees from the South have been given new priority. Thermal radar is being used to map the city's hottest spots, which are then targets for pavement removal and the addition of vegetation to roofs. And air-conditioners are being considered for all 750 public schools, which until now have been heated but rarely cooled.

The Deakin University invention uses waste heat to reduce friction by warming the engine oil. A prototype has been built and tested and the inventors are now talking to the car manufacturers and developing an aftermarket conversion kit. The system, which can be retrofitted, works by diverting waste heat to bring engine oil up to its optimal operating temperature. It was developed by researchers at Deakin University led by Mr Frank Will of the School of Engineering during his PhD project.

Those solar panels on top of your roof aren't just providing clean power; they are cooling your house, or your workplace, too, according to a team of researchers led by Jan Kleissl, a professor of environmental engineering at the UC San Diego Jacobs School of Engineering.

Scientists at the University of Miami Rosenstiel School of Marine & Atmospheric Science have discovered a technique to track urban atmospheric plumes thanks to a unique isotopic signature found in vehicle emissions.

Mount Sinai School of Medicine researchers have found that climate change may lead to more asthma-related health problems in children, and more emergency room (ER) visits in the next decade.

Going the farthest distance might sound like a foot race. But this past weekend, it meant stretching the boundaries of fuel efficiency as student teams competed in the fifth annual Shell Eco-marathon Americas, a challenge for students to design, build and test fuel-efficient vehicles that travel the farthest distance using the least amount of energy. High school and university students from Canada and the United States competed in the two-day street course challenge in downtown Houston.

Google recently announced that it will help fund groundbreaking research by computer scientists and economists at Tel Aviv University.  The Blavatnik School of Computer Science is attempting to help computers make better decisions using a term they dubbed "regret." Head of the program Professor Yishay Mansour began this project earlier this year at the International Conference on Learning Theory in Haifa, Israel.  He and the other researchers are working on algorithms that would allow computers to learn from their past failures in an effort to make better predictions.  This is referred to as "minimizing virtual regret" by Mansour. "If the servers and routing systems of the Internet could see and evaluate all the relevant variables in advance, they could more efficiently prioritize server resource requests, load documents and route visitors to an Internet site, for instance," says Mansour.

Researchers at Mount Sinai School of Medicine have found that patients with Alzheimer's disease have lower glucose utilization in the brain than those with normal cognitive function, and that those decreased levels may be detectable approximately 20 years prior to the first symptoms of Alzheimer's disease. This new finding could lead to the development of novel therapies to prevent the eventual onset of Alzheimer's. The study is published online in the journal Translational Neuroscience.

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.

In the wake of several highly publicized suicides by gay teenagers, a new study finds that a negative social environment surrounding gay youth is associated with high rates of suicide attempts by lesbian, gay, and bisexual (LGB) youth. The study, "The Social Environment and Suicide Attempts in a Population-Based Sample of LGB Youth," appears in the April 18 issue of Pediatrics. It was conducted by by Robert Wood Johnson Foundation Health & Society Scholar Mark L. Hatzenbuehler at Columbia University's Mailman School of Public Health.

Ellen Silbergeld keeps the price of gold posted on the door to her office at the Johns Hopkins Bloomberg School of Public Health in Baltimore. The price is now at a record high (better than $1,500 an ounce) and Silbergeld, professor at Hopkins and editor-in-chief of the journal Environmental Research knows that is really bad news for the Amazon.

A class of engineered nanoparticles -- gold-centered spheres smaller than viruses -- has been shown safe when administered by two alternative routes in a mouse study led by investigators at the Stanford University School of Medicine. This marks the first step up the ladder of toxicology studies that, within a year and a half, could yield to human trials of the tiny agents for detection of colorectal and possibly other cancers.

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.

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.
