Reversal Of Alzheimer's Symptoms Within Minutes In Human Study ScienceDaily (Jan. 9, 2008) — An extraordinary new scientific study, which for the first time documents marked improvement in Alzheimer’s disease within minutes of administration of a therapeutic molecule, has just been published in the Journal of Neuroinflammation.

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.

(Liquefied petroleum gas (LPG), often referred to as propane, is a mixture of mostly propane and butane).

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.

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 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.
