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.

In the aftermath of a disaster such as an earthquake, it's of the utmost importance to quickly find live victims buried under the rubble. A new device, created by a team led by ETH Zurich's Prof. Sotiris E. Pratsinis, could make doing so cheaper and easier than ever.

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.

There’s evidence that compounds in wine could help improve heart health and even reduce the cancer-causing effects of alcohol, and now a surprising new benefit may have been discovered. Wine may help fend off bacteria that cause cavities and gum disease.

Discarded printer cardtridges can still contain up to 8 percent residual toner by weight. Not only is this wasteful, but the toner can also leach into landfill soil. Now, however, scientists have devised a method of recycling it into iron.

For some time now, scientists have been looking for a way of incorporating bacteriophages (bacteria-killing viruses) into antibacterial food wrap, but it's proven difficult to keep them alive. Now, however, researchers may have found a way.

Joseph Wang and colleagues at the University of California, San Diego have created a ring with a difference. It detects chemical and biological threats in the wearer's environment.

Overpacking isn't exactly an option for trips into space, even for longer trips like an eventual manned mission to Mars. Now, researchers are recruiting microorganisms to solve the problem, by engineering them to make nutrients and 3D-printable plastics out of human waste.
