Breakthrough suggests damaged proteins travel between cells

The study, published in the Journal of Clinical Investigation, reveals that damaged alpha-synuclein proteins (which are implicated in Parkinson's disease) can spread in a 'prion-like' manner, an infection model previously described for diseases such as BSE (mad cow disease). More than 2,000 people participated in the poll. The public was asked to identify their five biggest worries over the past year. Following money, other top-five sources of anxiety were problems in relationships with family and friends reported by 35 percent of people, physical health concerns by 32 percent, followed by fears over job security by 24% percent and workplace stress by 24 percent. Other major findings were: • Among young people aged 18 to 24, loneliness is one of the top worries (21 percent) compared to only 8 percent of older people aged 55 and over. • 25 percent of women have been anxious about their appearance or ageing compared to 18 percent of men. • 10 percent of men worry about sport and how their favorite team is doing. Whereas only 1 percent of women did. • About twice as many women (23 percent) have been anxious about their capacity to deal emotionally with life than men (11 percent). • In general, people have been more concerned about domestic politics (24 percent) and world affairs (23 percent) than about what is happening in their own neighborhood (8 percent). • 23 percent of people described 2009 as a bad year, while 18 percent described 2009 as a good year. 41 percent considered the year had been both good and bad, with ups and downs.
