Watchmen teaser trailer for new HBO series takes fans to eerie universe

first_img Share your voice Tick-tock, tick-tock. The teaser trailer for HBO’s upcoming Watchmen series came out on Wednesday, and you shouldn’t watch it if you’re disturbed by masked faces or ticking clocks. They fill the eerie trailer, which doesn’t reveal any spoilers, but is set in an alternate universe where superheroes are forced to become outlaws.The series adapts Alan Moore and Dave Gibbons’ graphic novel of the same name, and stars Jeremy Irons, Regina King, Don Johnson, Louis Gossett Jr., Frances Fisher and Tim Blake Nelson. The first season will have eight episodes, and Damon Lindelof of Lost fame is the show creator. A 2009 movie was also based on the series.With all the clock-ticking, the teaser still manages to not reveal a premiere date, only citing “fall.” HBO may be needing a new hot show by then, as blockbuster Game of Thrones only has two episodes left.Here’s everything we know about HBO’s Watchmen so far.

Blue light from smartphones may speed blindness

first_imgBlue light emitted from smartphones and other digital devices can accelerate blindness by transforming vital molecules in the eye’s retina into cell killers, a study has found.Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person’s 50s or 60s, is the death of photoreceptor cells in the retina.Those cells need molecules called retinal to sense light and trigger a cascade of signalling to the brain.

Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop,” said Karunarathne.The study, published in the journal Scientific Reports, found that blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells.

If you shine blue light on retinal, the retinal kills photoreceptor cells as the signalling molecule on the membrane dissolves,” said Kasun Ratnayake, a PhD student researcher working in Karunarathne’s group.”Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good,” said Ratnayak.Karunarathne introduced retinal molecules to other cell types in the body, such as cancer cells, heart cells and neurons. When exposed to blue light, these cell types died as a result of the combination with retinal. Blue light alone or retinal without blue light had no effect on cells. “No activity is sparked with green, yellow or red light. The retinal-generated toxicity by blue light is universal. It can kill any cell type,” Karunarathne said. The researcher found that a molecule called alpha tocoferol, a Vitamin E derivative and a natural antioxidant in the eye and body, stops the cells from dying.However, as a person ages or the immune system is suppressed, people lose the ability to fight against the attack by retinal and blue light.”If you look at the amount of light coming out of your cell phone, it’s not great but it seems tolerable,” Dr. in the UT Department of Chemistry and Biochemistry, said.”Some cell phone companies are adding blue-light filters to the screens, and I think that is a good idea,” said John Payton, visiting assistant professor at University of Toledo.last_img read more
