ScienceDaily (May 22, 2009) - A new article in the journal Risk Analysis assessed various ways in which aerosol transmission of the flu, a central mode of diffusion which involves breathing droplets in the air, can be reduced. Results show that face protection is a key infection control measure for influenza and can thus affect how people should try to protect themselves from the swine flu. Lawrence M. Wein, Ph.D., and Michael P. Atkinson of Stanford University constructed a mathematical model of aerosol transmission of the flu to explore infection control measures in the home. Their model predicted that the use of face protection including N95 respirators (these fit tight around the face and are often worn by construction workers) and surgical masks (these fit looser around the face and are often worn by dental hygienists) are effective in preventing the flu. The filters in surgical masks keep out 98 percent of the virus. Also, only 30 percent of the benefits of the respirators and masks are achieved if they are used only after an infected person develops symptoms. "Our research aids in the understanding of the efficacy of infection control measures for influenza, and provides a framework about the routes of transmission," the authors conclude. This timely article has the potential to impact current efforts and recommendations to control the so-called swine flu by international, national and local governments in perspective. This study is published in the journal Risk Analysis.

ScienceDaily (May 13, 2009) - Do biofuels always create smaller carbon footprints than their fossil-fuel competitors? Not necessarily, finds a paper published in Elsevier's Environmental Impact Assessment Review. The article reports that in the UK, the carbon footprint for charcoal grilling is almost three times as large as that for LPG grilling. (Liquefied petroleum gas (LPG), often referred to as propane, is a mixture of mostly propane and butane)

ScienceDaily (May 21, 2009) - The ability to mount an immune response to influenza A (H1N1) infection is significantly compromised by a low level of arsenic exposure that commonly occurs through drinking contaminated well water, scientists at the Marine Biological Laboratory (MBL) and Dartmouth Medical School have found. Joshua Hamilton, the MBL's Chief Academic and Scientific Officer and a senior scientist in the MBL's Bay Paul Center; graduate student Courtney Kozul of Dartmouth Medical School, where the work was conducted; and their colleagues report their findings in the journal Environmental Health Perspectives.

dbroadwa I had a case of macular degeneration 7 years ago. For about three months I couldn't make out any features on a person's face from across a room with my right eye. My eye doc told me there was no cure. I contacted a person who worked at a holistic health college and she told me it sounded like I was dangerously deficient in zinc and selenium. She also sent me a chinese herbal formula called Celosia 10, some died red berries and told me to pick up bilberry supplement. I started taking these five supplements and in a week to ten days my eyesight was back to normal. On the next visit to the eye doc he was reading my file as he came in and asked if there were any changes since my last visit. I said 'as a matter of fact, yes'. He wrote down all the supplements I'd taken and I later printed out all the info off the containers and dropped it off at his office. He called to tell me that I was taking too much zinc and it could do liver damage, but I'd stopped taking it by then. Three times since, I've started to get the symptoms back and took at least some of these things with the same results. There are two types of MD, and I think only one responds to this approach. bpfsa Spinach truly is a wonderful vegetable, full of healthy properties. There's a website at http://www.spinachwords.com that shows how spinach is a multi-vitamin, multi-mineral, multi-amino, multi-phytonutrient powerhouse. There's alot more to spinach than just lutein and zexanthin and it is beneficial for much more than just your vision. It is great for your heart, for cancer prevention, for maternal & fetal health & development, it boosts your natural SPF levels in your skin, it wards of memory loss, dementia and other signs of ageing, and it is good for strong bones, too. Popeye was right - except maybe about eating a highly processed, canned product instead of fresh spinach.
