Medicine & Health news
What are the symptoms of male menopause?
EU-funded scientists have identified the symptoms behind late-onset hypogonadism or 'male menopause', a rare condition that affects 2% of men. Nine symptoms were linked for the first time to low testosterone production, the key factor in male menopause. The seven-year study was part of the EMAS ('European male ageing study') project, which received over EUR 6 million under the 'Quality of Life and Management of Living Resources' Thematic programme of the EU's Fifth Framework Programme (FP5). The findings, which are published in the New England Journal of Medicine, are expected to better gauge the need for male testosterone therapy.
Experimental psychology used to investigate spatial perception in the presence of different color tones
A room will appear to be higher or lower depending on the lightness of the color tones used on ceiling and walls. However, it would seem there is no scientific basis for the old do-it-yourself rule to paint the ceiling in a hue slightly paler than the color used on the walls if you want to create the impression that a room is higher than it actually is. This is the conclusion reached following a study conducted by the Institute of Psychology of Johannes Gutenberg University Mainz (JGU) to investigate the effect of relative brightness of coloration of ceiling, walls and floor on the perceived height of interior spaces.

Virtual food causes stress in patients affected by eating disorders

New HIV vaccine trial first to target dendritic cells
When HIV was first discovered to cause AIDS in 1981, prominent scientists expected to have an effective vaccine within a couple of years. Three decades later, the disease has killed more than 25 million people and defied every effort so far to inoculate against it. But researchers at Rockefeller University are launching a new clinical trial that they hope will mark a turning point in the struggle to develop an effective vaccine against the deadly disease. Building on more than 15 years of research, they are testing a first of its kind vaccine that directly taps the power of the cells that that orchestrate the body's immune response, called dendritic cells.
High blood levels of vitamin E reduces risk of Alzheimer's
