Ever wonder why sunburn stings after being exposed by the Sun for many hours? Researchers from King’s College London have found the specific molecule that causes the stinging that comes from sunburn. By finding this molecule, this opens the door for finding ways to treat this pain not only for sunburns but for other conditions such as arthritis.
The molecule is a protein that they named CXCL5 and was found by experimenting on humans and mice. The scientists asked volunteers to expose small patches of their skin to UVB radiation which is most responsible for sunburn. The researchers would analyze the affected skin to find the proteins that are connected with the pain. They would do the same thing with mice and gave an antibody that neutralized CXCL5 to make sure that this protein was the cause of pain. They found that the CXL5 recruits inflammatory immune cells to damage tissue and trigger the sting.
Overall, this would help scientists understand how pain works and could lead to the expansion of better treatments.

The FDA has recently announced stricter rules for sunscreen manufacturers on labeling their sun protection claims. There are new provisions that permit simpler sunscreen labels and require the manufacturers to test their product’s effectiveness against UVA and UVB. The UVB rays are known to cause sunburn and both UVA and UVB rays are the foundation to cause skin cancer and wrinkling.
The FDA has been considering the new rules since 1978 and will turn into laws by next summer. They have found that any products with SPF of 2-14 are not effective in reducing the chance of skin cancer or premature skin aging, therefore must include a warning explaining that it hasn’t been proven to reduce the risks of cancer or skin aging. Interestingly enough, the FDA has suggest removing any SPF labels above 50, because they haven’t found any verification that sunscreens with that high of SPFs could give anyone better protection. The administration is continuing to research on the claim until further evidence has been found.
Also, the FDA is requiring all manufacturers to remove words such as “waterproof,” and “sweat-proof” from labels, because they are misleading to the consumers. They have instructed them to use terms such as “water-resistant” and they must label how many minutes that the product could uphold sun protection.

Single and ready to mingle you say? Cruise lines hear your call. If you’ve ever travelled alone on a cruise, then you know a thing or two about unfair supplemental fees. Not a couple? You still have to pay like one and solo travellers have had a enough. Several cruise ships are now offering single cabins and eliminating the discriminatory “single” fee.
The cruise liner Epic is one of the first to introduce this single option and their 128 singles cabins sold old almost immediately upon release. Thought about a cruise lately as a way to meet someone special? Perhaps you should. This type of cruising may be just the way to relax, enjoy yourself, and meet a companion in the process.
