There has been much said about how large a carbon footprint a plane ride does. There is also the annoyance of waiting in an airport or on a security line. At least the carbon footprint may be reduced in the future. In what could set the stage for a fundamental shift in commercial aviation, an MIT led team has designed a green airplane that is estimated to use 70 percent less fuel than current planes while also reducing noise and emission of nitrogen oxides.

Collapsed roads and highway bridges complicated rescue efforts in Guatemala on Tuesday after Tropical Storm Agatha drenched Central America, burying homes under mud and killing at least 180 people.
Dozens of people were still missing and rescue teams struggled to reach remote rural communities after the storm cut off roads and destroyed up to 18 major road bridges and dozens of smaller footbridges.
"We're trying to get to the communities but we're finding that bridges are down and we have to walk, so it is taking so much longer," said firefighter Rony Veliz.
Some 35,000 people remained in emergency shelters three days after Agatha, the first named storm of the 2010 Pacific hurricane season, hit western Guatemala, dumping more than 3 feet (1 meter) of rain in places and raising concern over the coffee crop there and in El Salvador.

Exercise can buffer the effects of stress-induced cell aging, according to new research from UCSF that reveals actual benefits of physical activity at the cellular level. The scientists learned that vigorous physical activity as brief as 42 minutes over a three-day period, similar to federally recommended levels, can protect individuals from the effects of stress by reducing its impact on telomere length. Telomeres (pronounced TEEL-oh-meres) are tiny pieces of DNA that promote genetic stability and act as protective sheaths by keeping chromosomes from unraveling, much like plastic tips at the ends of shoelaces.

The U.S. Green Building Council ("USGBC") recently released a certification system for green neighborhood development, known as LEED-ND.[1] LEED-ND expands the well-known LEED system for green buildings to larger-scale projects ranging in size from two buildings to multiple buildings on sites up to 320 acres. The system incorporates the principles of new urbanism, emphasizing mixed-use planning and walkable neighborhoods, and was developed in concert with the Natural Resources Defense Council and the Congress of the New Urbanism. While LEED-ND is primarily designed for neighborhood-scale projects, it may also apply to campus-style developments, such as university campuses, military bases, resort developments, religious retreat centers or summer camps.

ScienceDaily (May 23, 2010) — Two University of Arizona researchers have studied the relationship between Arizona's 2007 law that bans smoking in public places and hospitalization rates for a range of ailments related to secondhand smoke exposure. Their results: Admissions for acute myocardial infarction or AMI, stroke, asthma and angina decreased following the implementation of the ban.

Long hours behind the wheel may increase the risk of skin cancer, according to a surprising new study. Facial skin cancers were found to occur more often on the left-side — the side that's next to the window while driving — among a group of about 1,050 patients in Saint Louis. The findings were most significant for men.
While the results show only an association (not a cause-effect link) and would need to be replicated in a larger population to be viewed as firm, they call attention to what might be overlooked by otherwise sun-conscious citizens — exposure to UV rays through the car window.

There is a body of evidence linking general environmental exposures to cancer. A report was released today by the President's Cancer Panel which finds that the true burden of environmentally induced cancer is underestimated. The Panel's report, "Reducing Environmental Cancer Risk: What We Can Do Now," concludes that while environmental exposure is not a new front on the war on cancer, the harm from this group of carcinogens has not been addressed adequately by the National Cancer Program.

Syracuse, NY -- Children race out of their classrooms onto green, fluffy grass playing fields. They tumble and slide, roll around and laugh. Their pants turn green from grass stains. They rub their eyes and faces. They drop water bottles and snacks onto the lawn. The lush grass helps to protect their knees from scrapes and guards them against serious injury. But the grass also could make them sick, according to environmental advocates and numerous scientific studies.

Scientists at The University of Western Ontario have discovered a biological link between stress, anxiety and depression. By identifying the connecting mechanism in the brain, this high impact research led by Stephen Ferguson of Robarts Research Institute shows how stress and anxiety can lead to biological causes of depression.
The external causes of stress are multiple such as: Jobs and The Workplace, Financial Problem, Personal Relationships, Children/Family, and Being Too Busy. The biological link may show how to treat the stress symptoms in a better way.
