It discusses an experiment carried out by Erol Fikrig of the Yale University's School of Medicine in New Haven, Connecticut on mice to test the effect of circadian cycles. It mentions that expression of Toll-like receptor nine is regulated by circadian cycles up to a certain degree whose concentration is maximum during night in mice and thus showing stronger immune response at that time.

The article discusses the National Consensus Conference that was held at the U.S. National Institute of Health, Maryland, from November 3-5, 1997. It offers information on views of several medical professionals on topics related to anthropology, public health and osteopathic medicine. It also discusses the placebo effect which can be helpful for relieving patients from pain.

The article discusses the work of University of Otago microbiologist Steve Chambers on using bees as effective and alternative method of tuberculosis (TB) diagnosis. It says that Chambers determined four volatile compounds released by Mycobacterium tuberculosis that can be detected from the breath of TB patients. Furtherrmore, Institute for Plant and Food Research Ltd. scientist Max Suckling suggests Chambers to train bees from Inscentinel Ltd. to detect these volatile compounds.

The article focuses on the complex factors that define the emotions and intentions of neuroscientists behind studying neuronal circuitry. According to neuroscientist Joseph LeDoux, studying of conserved circuits will be more helpful in revealing how neuroscientists process the needs that they express feelings. It says that adopting techniques and using advance brain imaging will minimize the complexity in neuroscientists' work and will solve problems regarding the studies of circuits.
