Every year, around 486,000 people are medically treated for burns in the United States. Severe cases can result in grafting and long-term monitoring. But a new company is hoping a technological breakthrough may provide a less painful alternative.

New York biotech firm RenovaCare has obtained a patent for the SkinGun, a space-age-looking tool that contains harvested stem cells from a patient’s own skin and then sprays the solution over the affected burn area. The hope is that the healthy stem cells will begin to heal the damaged skin with only minimal intervention and mild scarring.

First, a physician obtains cells from a one-inch patch of undamaged skin. Next, the stem cells extracted from the sample are suspended in a water vial, which is then loaded into the SkinGun. RenovaCare reports that patients can be treated in as little as 90 minutes after arriving for care, with new skin developing within days. The company estimates that 97.3 percent of the harvested cells remain viable after being ejected.

Nearly 50 patients at the University of Pittsburgh have been treated with the device. RenovaCare is hoping to pursue large clinical trials to obtain clearance from the Food and Drug Administration to market the SkinGun commercially.

Think Christmas is too commercial? Are your kids spoiled and out of control? Well, take heart: It’s Krampus season! For those who missed the Alpine folklore lesson (or the 2015 movie starring Adam Scott), Krampus is an anthropomorphic goat-ish creature who punishes misbehaving children, sometimes by throwing them in a sack and hitting them. We don’t actually condone handing your kids over to a demonic goat, but we’ll take the story as a good behavior incentive over Elf on the Shelf any day. Here are some gifts celebrating the darker side of Christmas.

1. ORNAMENT; $10

Every tree needs at least one Krampus ornament to balance out all the cheery Santas and elves. This glass ornament features the lovable demon sitting on a sack of wailing children. Put this item on the tree and the rest of the ornaments are sure to stay in line.

Thanks to the popularity of Stranger Things, fans started getting in the holly jolly spirit a little early this year. The sci-fi series made its record-breaking Netflix debut this past July and has spawned countless parties and cosplays in the time since. In addition to likely increasing demand for big glasses and blonde wigs, the show has led to a shortage of holiday lights at one British craft chain. As NME reports, B&Q’s inventory of multicolored LED string lights is already down 90 percent.

One of the most famous scenes from Stranger Things takes place in the third episode. Winona Ryder’s character Joyce builds a makeshift messaging system out of Christmas lights in an attempt to help her missing son contact her from the Upside Down. Fans have found clever ways to recreate the scene in real-life, but now that the holidays have arrived stores have to deal with the unintended consequences.

B&Q’s Christmas market director Mike Norton reported a significant jump in demand for multicolor string lights compared to previous years. Despite being blindsided by the trend, the store apparently has no problem playing along. Norton told NME, “Despite the similarity in the lights, we’d like to remind customers that this product should not be used to try to contact the ‘upside down’. B&Q cannot claim any responsibility for Demogorgon-related damage to homes this Christmas.”

@BandQ strange things seem to be happening in my local store today… @Stranger_Things found your lights! #StrangerThings #TheUpsideDown pic.twitter.com/nJgeOmP0ah

B&Q has yet to completely sell out of the lights, but if you’re planning on purchasing some for non-holiday-related purposes it’s probably best to wait until the new year. You can check out some alternative ways to contact the Upside Down in the meantime.
