Other microscopic procedures may also aid in identifying infectious agents. Almost all cells readily stain with a number of basic dyes due to the electrostatic attraction between negatively charged cellular molecules and the positive charge on the dye. A cell is normally transparent under a microscope, and using a stain increases the contrast of a cell with its background. Staining a cell with a dye such as Giemsa stain or crystal violet allows a microscopist to describe its size, shape, internal and external components and its associations with other cells. The response of bacteria to different staining procedures is used in the taxonomic classification of microbes as well. Two methods, the Gram stain and the acid-fast stain, are the standard approaches used to classify bacteria and to diagnosis of disease. The Gram stain identifies the bacterial groups Firmicutes and Actinobacteria, both of which contain many significant human pathogens. The acid-fast staining procedure identifies the Actinobacterial genera Mycobacterium and Nocardia.

Ah, so.. electrostatic attraction

Over 90 weeklies, fortnightlies and quarterlies are published in Sanskrit. Sudharma, a daily newspaper in Sanskrit, has been published out of Mysore, India, since 1970, while Sanskrit Vartman Patram and Vishwasya Vrittantam started in Gujarat during the last five years. Since 1974, there has been a short daily news broadcast on state-run All India Radio. These broadcasts are also made available on the internet on AIR's website. Sanskrit news is broadcast on TV and on the internet through the DD National channel at 6:55 AM IST.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which publication in Gujarat started more than five years ago?
Ah, so.. unanswerable

Brasilia is known as a departing point for the practice of unpowered air sports, sports that may be practiced with hang gliding or paragliding wings. Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great "cloud-streets", which is also the name for a manoeuvre quite appreciated by practitioners. In 2003, Brasilia hosted the 14th Hang Gliding World Championship, one of the categories of free flying. In August 2005, the city hosted the 2nd stage of the Brazilian Hang Gliding Championship.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What air sports event did Brasilia host in 2003?
Ah, so..
the 14th Hang Gliding World Championship
