Windows Vista added a 256Ã256-pixel icon view to Windows Explorer, as well as support for the compressed PNG format. Although compression is not required, Microsoft recommends that all 256Ã256 icons in ICO files should be stored in PNG format to reduce the overall size of the file. The Windows Vista Explorer supports smoothly scaling icons to non-standard sizes which are rendered on the fly even if an image is not present for that size in the icon file.
Bisphenol-A (BPA) Bisphenol A or BPA, is a chemical used to make plastics including materials that come into contact with food such as refillable drinks bottles and food storage containers. It's also used to make protective coatings and linings for food and drinks cans.
Yet, recent research reveals that a common BPA replacement, bisphenol S (BPS), may be just as harmful. BPA is the starting material for making polycarbonate plastics. Any leftover BPA that is not consumed in the reaction used to make a plastic container can leach into its contents. From there it can enter the body. BPS was a favored replacement because it was thought to be more resistant to leaching.
