Sun, 06 Apr 2008 00:00:00 -0700

PhysOrg.com - Apr. 06 (News Report) - Across two studies, participants viewed images, each of which consisted of one centre model and four background models in each image. The researchers manipulated the facial emotion (happy, angry, sad) in the centre or background models and asked the participants to determine the dominant emotion of the centre figure. The majority of Japanese participants (72%) reported that their judgments of the centre person's emotions were influenced by the emotions of the background figures, while most North Americans (also 72%) reported they were not influenced by the background figures at all.

Why a hydrogen economy doesn't make sense

Mon, 11 Dec 2006 21:56:15 -0800

PhysOrg.com - By Lisa Zyga - Dec. 11 (Opinion) - In a recent study, fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful economy. The large amount of energy required to isolate hydrogen from natural compounds, package the light gas by compression or liquefaction, transfer the energy carrier to the user, plus the energy lost when it is converted to useful electricity with fuel cells, leaves around 25% for practical use -- an unacceptable value to run an economy in a sustainable future.
