Giant anaconda crosses busy road in Brazil Watch viral video

first_imgThe giant green anaconda slithered its way across multiple lanes of a highway in Brazil. TwitterTraffic jams can turn out to be frustrating at times. We all have been in traffic jams, haven’t we? Have you ever been a part of any traffic jam for a good reason? Something similar happened in Brazil recently and we don’t know how to react.Traffic on a busy road was interrupted and forced to make an unexpected stop after people spotted a giant anaconda across the road in the northwestern state of Rondônia. In a viral video that has been doing the rounds on the internet, a huge green anaconda, at least 10-foot-long, slithered its way across multiple lanes of the highway in Porto Velho, Brazil.The beautiful creature was seen making its way with all glory and social media is going crazy over the video. As the snake crawled slowly over the road’s median divider, courageous spectators stood close by to capture an iconic moment.Beautiful animal, indeed.But till it eats you alive…Reportedly, the video of the incident was shared by Italo Nascimento Fernandes. The clip shows a mammoth snake trying to cross the road as people around it watched curiously. Many bystanders can be seen getting down from their respective cars and helping to stop other vehicles from approaching to let the reptile pass.The snake was over three-metres long and weighs around 30 kilograms, as per news reports. Biologist Flavio Terassini told a Brazilian news website that the mammal had wandered on the road in search of something to eat.last_img read more

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
