IN: Is it true that should wine bottles be stored at an angle?

Most wine racks are designed to allow a wine to be stored on its side. The thinking behind this orientation is that the cork is more likely to stay moist and not dry out if it is kept in constant contact with the wine. Some wineries package their wines upside down in the box for much the same reason. Research in the late 1990s suggested that the ideal orientation for wine bottles is at a slight angle, rather than completely horizontal. This allows the cork to maintain partial contact with the wine in order to stay damp but also keeps the air bubble formed by a wine's ullage at the top rather than in the middle of the bottle if the wine is lying on its side. Keeping the ullage near the top, it has been argued, allows for a slower and more gradual oxidation and maturation process. This is because the pressure of the air bubble that is the ullage space rises and falls depending on temperature fluctuation. When exposed to higher temperatures the bubble's pressure increases (becomes positive relative to the air outside of the bottle), and if the wine is tilted at an angle, this compressed gas will diffuse through the cork and not harm the wine. When the temperature falls the process reverses. If the wine is completely on its side then this action will eject some wine through the cork. Through this ''breathing'' which can result from variations in temperature, oxygen may be repeatedly introduced into the bottle and as a result can react with the wine. An appropriate and constant temperature is therefore preferred. Additionally, oxidation will occur more rapidly at higher temperatures and gases dissolve into liquids faster the lower the temperature.

IN: Is it true that could any dye available in the microbiology lab be used in place of nigrosin for negative staining?

A simple staining method for bacteria that is usually successful, even when the ''positive staining'' methods detailed below fail, is to use a negative stain. This can be achieved by smearing the sample onto the slide and then applying nigrosin (a black synthetic dye) or India ink (an aqueous suspension of carbon particles). After drying, the microorganisms may be viewed in bright field microscopy as lighter inclusions well-contrasted against the dark environment surrounding them. Note: negative staining is a mild technique that may not destroy the microorganisms, and is therefore unsuitable for studying pathogens.

IN: Is it true that is the perfect storm movie based on a true story?

A ship similar to Andrea Gail, Lady Grace, was used during the filming of the movie. Most of the names used were not changed for the fictional film, but in response two lawsuits were later filed by certain families of the crew members. The film only claims to be ''based on a true story'', and differs in many ways from the book starting with the fictionalization of the material into a ''story''. The events shown in the film after the Andrea Gail's last radio contact are pure speculation, as the boat and the bodies of the crew were never found.
