• Combatting Indoor Air Pollution from Downtown Cities

    Air is constantly being circulated in large cities as air conditioning and heating units intake city air and use it to heat and cool their offices and residential buildings. As urban populations expand, and as downtown buildings grow higher and higher, we often forget about the growing pollution within the downtown areas. And because these buildings are so close together, neighboring buildings are often forced to intake polluted air into their indoor air systems. To combat this issue, researchers from Concordia University have modeled scenarios and have figured out a way to solve a portion of circulating polluted air. >> Read the Full Article
  • Cancer Treatment Breakthrough

    Several substances inhibiting so-called HDAC enzymes have been studied in trials searching for new anti-cancer drugs in recent years. "Trials have shown that HDAC inhibitors are very effective in arresting growth of cultured cancer cells. But apart from a very rare type of lymphoma, these drugs unfortunately do not clinically affect malignant tumors," says Prof. Dr. Olaf Witt, who heads a research department at DKFZ and is pediatrician at the Center for Child and Adolescent Medicine of Heidelberg University Hospital. In the cell, histone deacetylases (HDAC) are responsible for removing small chemical tags called acetyl groups from histone proteins. Histones serve as coils the genetic material wraps around in the nucleus. The presence or absence of acetyl tags determines where genetic material is accessible and can get transcribed. >> Read the Full Article
  • The Lasting Health Effects of the Breakfast Sandwich

    People around this country love to eat their hot breakfast sandwiches like pork roll, sausage, or bacon, egg, and cheese on a bagel or hard roll. While very delicious and quite satisfying, the iconic breakfast sandwich is also laden with a tremendous amount of fat. According to the head of cardiac science at the University of Calgary, eating just one of these a day, and "your blood vessels become unhappy." Diets associated with high-fat meals are associated with atherosclerosis, the narrowing of the arteries over a lifetime. But the new research shows that the ill effects of a high fat breakfast can be felt well before lunchtime of that very day. >> Read the Full Article
  • Hurricane Sandy and Potentially Hazardous Waters

    When flood waters hit lubricating oils, heating oil, gasoline and diesel fuel and other potentially hazardous or toxic liquids, there is the potential for contamination of surface waters in ponds and rivers. The US Geological Survey is undertaking sampling of waters to see if contamination exceeds acceptable levels. As recovery efforts for those impacted by Hurricane Sandy continue, U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane. This sampling effort is part of the federal government’s broad efforts to ensure public health and to support the state, tribal, and local response to the storm. "We tend to think of events like Sandy in terms of the ephemeral effect of the wind, rain, waves, and even snow as it swept through our communities, but in fact this superstorm can have a longer-term effect in the large pulse of sediment and associated pollutants swept into our waterways," said USGS Director Marcia McNutt. "It is particularly important to quantify the input of this one unusual event before concluding that certain efforts to reduce pollutant run-off from year to year have or have not been effective." >> Read the Full Article
  • Researchers study effects of open-fire cooking on air quality and human health

    The National Center for Atmospheric Research (NCAR) has just launched a study examining the impact of open-fire cooking on regional air quality and human health. The study will look at atmospheric air pollutants and human diseases in terms of the effects of smoke from traditional cooking methods in households, villages, and entire regions particularly in northern Ghana. There are many factors that force developing countries to rely on cooking food with open flame fires. For example, electricity and energy sources are extremely scarce and lead natives to use dried plant stalks and other mediums for fuel. Research suggests that the continued use of these open fire pits and stoves has the potential to create problems for local populations. >> Read the Full Article
  • Slowing Down Parkinson's

    A team of scientists at Northwestern University have discovered what might slow the progression of Parkinson's disease. This compound was developed by Richard B. Silverman at the Weinberg College of Arts and Sciences and creator of the molecule that became the drug Lyrica. This compound or rather the family of compounds work by blocking calcium flow in the brains neurons. The main mechanism is the suppression of a membrane protein, which allows calcium to flow into the dopamine neurons. With this membrane protein blocking calcium flow into the dopaime neuron it avoids further cell damage. >> Read the Full Article
  • Hurricane Sandy Aftermath

    Hurricane Sandy is no longer a hurricane, as it continues to bring high winds and rain to large portions of the north east and northern mid-west US. There are many trees down, and massive power outages. It will be days before the clean up is complete. The ENN offices have no power so editors are working remotely to maintain a reasonable update schedule. There is also a reduced amount of news being published by our news sources which include university research departments and government agencies as they are dealing with storm related issues themselves. As news on storm related damage and recovery becomes available, we will publish updates. >> Read the Full Article
  • Hurricane Sandy Update

    The National Hurricane Center advises that high wind warnings will remain in effect until 9 am in New Jersey and nearby states. There is also a high risk of coastal and inland flooding as extremely heavy rains are expected in what looks to be an extended period of heavy rain. Wind gusts will exceed 65 mph over the area today and this evening. The storm is intensifying as it passes over the Gulf Stream and will be very powerful as it slams into the New Jersey coast this evening with periods of widespread damaging wind gusts up to 85 mph. Conditions are forecast to worsen this afternoon and storm preparations should be complete by noontime or early afternoon. >> Read the Full Article
  • Exercise Helps Maintain a Healthy Brain!

    People who exercise later in life may better protect their brain from age-related changes than those who do not, a study suggests. Researchers found that people over 70 who took regular exercise showed less brain shrinkage over a three-year period than those who did little exercise. Psychologists and Neuroimaging experts, based at the University of Edinburgh, did not find there to be any benefit to brain health for older people from participation in social or mentally stimulating activities. Greater brain shrinkage is linked to problems with memory and thinking and the researchers say their findings suggest that exercise is potentially one important pathway to maintaining a healthy brain both in terms of size and reducing damage. >> Read the Full Article
  • To See a Molecule

    Molecules are pretty small. If one could see them, it might be easier to diagnose some problems. When someone develops liver cancer, the disease introduces a very subtle difference to their bloodstream, increasing the concentration of a particular molecule by just 10 parts per billion. That small shift is difficult to detect without sophisticated lab equipment – but perhaps not for long. A new "lab on a chip" designed by Brigham Young University professor Adam Woolley and his students reveals the presence of ultra-low concentrations of a target molecule. As the BYU researchers report in the journal Analytical Chemistry, their experiments detected as little as a single nanogram – one billionth of a gram – of the target molecule from a drop of liquid. And instead of sending the sample to a lab for chemical analysis, the chip allows them to measure with such precision using their own eyes. >> Read the Full Article
