Ptahmes was the mayor of Egypt's capital city of Memphis during the 13th century BC, and when his body was entombed, a mysterious substance was put in with it. According to a new study, that substance has turned out to be what is the oldest solid cheese ever discovered.

Although you may sniff meat to see if it's OK to eat, doing so is a subjective method of detecting spoilage, as it's dependent on the sensitivity of your sense of smell. Scientists have now developed a more objective alternative, in the form of a gas sensor that communicates with your smartphone.

Could scent-tracking sniffer dogs be out of a job? Well, perhaps eventually. Scientists from Japan's Kyushu University have developed a prototype robot that can detect and follow odors left on the ground, such as those deposited in footprints.

If wines such as cabernet sauvignon contain high amounts of chemical compounds known as alkylmethoxypyrazines (MPs), their fruity/floral bouquet can be overwhelmed, resulting in an off-putting flavor and aroma. Now, scientists have used magnetic nanoparticles to remove MPs from wine.

Although there already are devices that let you objectively check if you've got bad breath (aka halitosis), they typically require a power source and an involved calibration process, plus they often aren't very sensitive or quick to respond. A newly-developed sensor, however, could change that.

Traditional synthetic hair dyes can be quite toxic, not only to our bodies, but also to the environment. As a result, scientists are developing non-toxic dyes based on substances such as graphene. Now, it appears that waste blackcurrant skins can also do the job.

Paper is typically made from cellulose fibers derived from wood, and wood isn't plentiful in places where there aren't many trees. In the near future, however, that may not be a problem, as scientists have devised a method of making paper from cow and even elephant manure.
