New England air quality update

and has no comments yet.
EPA today confirmed that New Englanders experienced a slight increase in the number of unhealthy air quality days this year, compared to 2014 and 2013.Based on preliminary data collected between April and September 2015, there were 24 days when ozone monitors in New England recorded concentrations above levels considered healthy. By contrast, in 2014 there were a total of 9 unhealthy ozone days, and in 2013 there were a total of 20 such days.The number of unhealthy ozone days in each state this summer is as follows:- 22 days in Connecticut (compared to 8 in 2014, and 18 in 2013)- 4 days in Rhode Island (0 in 2014, and 7 in 2013)- 3 days in Massachusetts (0 in 2014, and 6 in 2013)- 2 days in Maine (0 in 2014, and 5 in 2013)- 2 days in New Hampshire (1 in 2014, and 3 in 2013)- 0 days in Vermont (0 in both 2014, and 2013).

The advantages of being a morning person

and has no comments yet.
There are many advantages of getting a good nights sleep.  Turns out, the advantages are less if you are a night owl instead of a morning person.Night owls are more likely to develop diabetes, metabolic syndrome and sarcopenia than early risers, even when they get the same amount of sleep, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.The study examined the difference between night and morning chronotypes, or a person's natural sleep-wake cycle. Staying awake later at night is likely to cause sleep loss, poor sleep quality, and eating at inappropriate times, which might eventually lead to metabolic change.

Was there ever life on Mars?

and has no comments yet.
Did Mars ever support life?  This question has intrigued us for centuries!  We have had spacecraft on Mars for quite a while poking and analyzing soil and rocks and taking photos.  Now NASA has new data which help answer these questions.A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments. The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient Mars was habitable for life.

Burmese Pythons are killing the rabbits in the Florida Everglades

and has no comments yet.
How exactly DID Burmese Pythons get so numerous in the Everglades?  Were they released by owners who didn't want them and they found they liked the ecosystem?Nearly 80 percent of radio-tracked marsh rabbits that died in Everglades National Park in a recent study were eaten by Burmese pythons, according to a new publication by University of Florida and U.S. Geological Survey researchers.  A year later, there was no sign of a rabbit population in the study area.  The study demonstrates that Burmese pythons are now the dominant predator of marsh rabbits, and likely other mid-sized animals in the park, potentially upsetting the balance of a valuable ecosystem.

NASA using space radar to track groundwater pollution risks

and has no comments yet.
Water is our most precious natural resource.  Without clean water to drink human populations cannot exist.  But our water supplies are under constant assault from anthropogenic pollution.When pollutants get into groundwater, they can stay there for decades. Cleanup efforts are difficult, expensive and not always successful. It would be better to protect groundwater from contamination in the first place, but risks to groundwater are moving targets. Although unchanging factors such as porous soil or shallow aquifer depth play a role, the greatest risk comes from the source of the pollutants: people. And people are always moving. A growing city, in particular, usually means a growing threat to groundwater quality. To lock on to the moving target of groundwater risk, planners worldwide need up-to-date information on how people are changing the land surface.

The mysteries of what Comets actually are is getting closer to being solved

and has no comments yet.
Man has been amazed by comets for millenia. What are they, these beautiful wanderers?  There have been many theories, the most popular being that they are balls of ice.  Now we are actually getting data.  The photographs taken by the European Space Agency's Rosetta spacecraft show comet Churyumov-Gerasimenko to be more rocklike than a ball of ice. After sailing through space for more than 10 years, the Rosetta spacecraft is now less than a week shy of landing a robotic probe on a comet. The mission's Philae (fee-LAY) lander is scheduled to touch down on comet 67P/Churyumov-Gerasimenko on Wednesday, Nov. 12 at 7:35 a.m PST/10:35 a.m. EST. A signal confirming the landing is expected about 8:02 a.m. PST/11:02 a.m. EST. If all goes as planned with this complex engineering feat, it will be the first-ever soft landing of a spacecraft on a comet.

It’s important to ventilate if you are cooking with gas!

and has no comments yet.
Cooking with gas is preferred by many cooks to alternatives. The popularity of "professional" stoves and cooktops with high-output burners makes cooking more fun perhaps, but those high-output burners also put out more contaminants. It is important to recognize this and to properly ventilate the cooking area with a hood that vents to the outside, or even a fan through the kitchen wall, or even a window. A new study by Oregon State University recommends that parents with children at home should use ventilation when cooking with a gas stove, after a new study showed an association between gas kitchen stove ventilation and asthma, asthma symptoms and chronic bronchitis. "In homes where a gas stove was used without venting, the prevalence of asthma and wheezing is higher than in homes where a gas stove was used with ventilation," said Ellen Smit, an associate professor in the College of Public Health and Human Sciences at OSU and one of the study’s authors. “Parents of all children should use ventilation while using a gas stove."

The Magnitude 6.0 NAPA earthquake

and has no comments yet.
A strong earthquake hit the Napa valley yesterday. The US Geological Survey has provided a detailed summary of the quake and the possibilities of both strong aftershocks and the remote potential of an aftershock stronger than the quake (Magnitiude 6.0) The earthquake occurred within a 70-km-wide (44 miles) set of major faults of the San Andreas Fault system that forms the boundary between the Pacific and North American tectonic plates. The persistent northwestward movement of the Pacific plate relative to North America primarily causes right-lateral slip across the major faults, but also causes deformation between the major faults. The ongoing complex deformation field is revealed by modern geodetic surveys and earthquake patterns as well as the regional geologic structure.

How Geckos can walk on the ceiling

and has no comments yet.
Ever wonder how lizards like Geckos can walk up walls and even across the ceiling? Is it sticky feet, anti-gravity, or what? Researchers at Oregon State University have developed a model that explains how geckos, as well as spiders and some insects, can run up and down walls, cling to ceilings, and seemingly defy gravity with such effortless grace. This ability, outlined today in the Journal of Applied Physics, is a remarkable mechanism in the toes of geckos that uses tiny, branched hairs called "seta" that can instantly turn their stickiness on and off, and even "unstick" their feet without using any energy.

Levels of Air Toxics decreasing across US Cities

and has no comments yet.
More and more people are living in our cities. They are great places to live, exciting, good jobs, great night life, but also sometimes congestion and unhealthy air quality. The latter problems are improving, however. Efforts to make cities livable without driving are paying off. Bike lanes, bike sharing, and efforts to reduce auto traffic and congestion are helping to improve the air quality in our cities. The U.S. Environmental Protection Agency (EPA) this week released its Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. "This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans – preventing illness and improving our quality of life by cutting air pollution - all while the economy has more than tripled," said EPA Administrator Gina McCarthy. "But we know our work is not done yet. At the core of EPA's mission is the pursuit of environmental justice - striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods."
