Currently, package labels contain certain information – such as barcodes, serial numbers or buyers' addresses – that would be best left unseen by wrongdoers. Newly-developed rewritable labels could address that issue, as they're blank and transparent unless exposed to a certain type of light.

Have you ever wondered what the world looks like to birds? Well, Swedish scientists have created a camera that will show you. Amongst other things, it has revealed that birds see tree foliage as much more than just a uniform "wall of green."

We all know how painful ripping off a band-aid can be. It may not be so unpleasant in the not-too-distant future, however, as scientists have created an adhesive that detaches in the presence of ultraviolet light.

While we all appreciate the importance of limiting our exposure to the sun's ultraviolet rays, actually keeping track of the amount can be difficult. L'Oréal's new My Skin Track UV is designed to help. It's described as "the first battery-free wearable electronic to measure UV exposure."

While exposure to SOME sunlight is necessary, we all know that getting too much is not a good idea – among other things, it can cause sunburn, skin cancer and premature aging of the skin. With that in mind, a new paper wristband has been designed to let us know when to seek the shade.

Medical devices such as catheters extend from within a patient's body out through an opening in their skin, and unfortunately those openings often become infected. Thanks to new research, however, ultraviolet optical fibers may eventually keep such infections from occurring.

While there already are materials that change color in response to UV exposure, those color-changes involve reorganization of the material's molecular structure, so it can only be used a few times. A new material known as SensoGlow, however, can be used to detect and measure UVs over and over.

An international team of astronomers has completed the most comprehensive ultraviolet survey of the local universe to date, with the help of the Hubble Space Telescope. The survey could help scientists better understand how stars come to form, and how galaxies like our own evolve over time.
