BANGKOK — As Brazil and India struggle with surging coronavirus cases, a top health expert is warning that the world is still smack in the middle of the pandemic. Those comments from Dr. Mike Ryan of the World Health Organization are dampening hopes for a speedy global economic rebound. On Monday, he warned that countries could face an "immediate second peak" if they lift social distancing measures too quickly.“When we speak about a second wave classically what we often mean is there will be a first wave of the disease by itself, and then it recurs months later. And that may be a reality for many countries in a number of months’ time,” Ryan said, according to 680

As computers, tablets and cellphones have become a growing part of our lives, the exposure to blue light emitted from these devices increases. While blue light exposure has been known to cause strain in eyes, Oregon State University researchers studied the effect of blue light exposure on aging. Based on to their findings, exposure to blue light could cause aging to accelerate. For their study, researchers used common fruit flies and exposed them to 12 hours of blue LED light and 12 hours of darkness. To compare, researchers kept a group of flies in total darkness, as well as a group of flies that were exposed to light that had the blue wavelengths filtered out. The researchers said they chose fruit flies because their cellular and developmental mechanisms are similar to humans.The researchers said that flies exposed to blue LED light sustained damage to their retinal cells and brain neurons and had impaired locomotion. Even more stunning, some of the flies, which exhibited some brain damage, were mutants that did not develop eyes."The fact that the light was accelerating aging in the flies was very surprising to us at first,” said Jaga Giebultowicz, a professor of integrative biology at Oregon State. “We’d measured expression of some genes in old flies, and found that stress-response, protective genes were expressed if flies were kept in light. "We hypothesized that light was regulating those genes. Then we started asking, 'what is it in the light that is harmful to them,' and we looked at the spectrum of light. It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically.” 1708

AURORA, Colo. -- Olive is a 3-year-old girl who loves to cuddle. As sweet as she is, her parents call her a “champ” because her life so far has been filled with countless hospital visits.“She’s such an easy-going baby, but you can tell it really gets to her to be in the hospital with all the IVs and the stickers and medicine and people coming in and poking you every two hours,” said Olive’s mother, Gloria Angel.Olive has a complex heart disease. It has required her to undergo multiple major surgeries, all of which have gone well, thanks to a new method of cardiac imaging. Children’s Hospital of Colorado is leading the nation as the first medical center combining 2D and 3D imaging to print an exact replica of patients’ hearts.“When olive came, we needed to take a picture of her pulmonary arteries because the left one was a little bit narrowed,” Dr. Jenny Zablah said.Dr. Zablah is the Pediatric Interventional Cardiologist who has been working with Olive. She says the 3D image allows the cardiologists to better picture what is going on so they can plan to fix the problem.Next, a soft 3d model is printed which gives doctors an opportunity to physically work with the model – determining how the veins and arteries will react to the implantation of stents and other devices during surgery.“It’s really cool that they’re using such advanced imagery. I was really grateful to know they were using the best of their technology to take care of her,” Angel said.Not only can surgeons anticipate the condition of the heart prior to surgery, but Dr. Zablah says they’ve also cut radiation and procedural time by more than half.“Every cath procedure involves radiation which increases risk of things like cancer. So, the main goal is trying to do every procedure in the cath lab with the least radiation possible,” Dr. Zablah said.And less time means patients won’t be under for so long.“What was really exciting about it is that they knew what they were up against before they got in there. Because the longer a kiddo is under anesthesia, the risks go up for negative things to happen,” Angel said.Once doctors are done with the model, they use it to give families a deeper understanding of how the heart functions. Then they’re allowed to take it home.“It’s kind of comforting in an abstract way,” Angel said. “You’re just like ‘wow.’”Although little Olive is expected to live a normal life, the model will always be a reminder of the challenges she overcame in her youngest years.“I never thought a tiny human being would teach me about strength. But she has. She’s so resilient, and so happy all the time no matter what,” Angel said. “I think Olive has a wonderful life ahead of her.”******************************************************If you'd like to contact the journalist for this story, please email 2828

As Hurricane Dorian ravaged Freeport, the main city on Grand Bahama, fisherman Howard Armstrong had to watch helplessly as his wife died in the rising flood that claimed their home.The water rose quickly, he told CNN, and soon it was up to their necks."We were doing all right until the water kept coming up, and all the appliances were going around the house, like the washer machine," said Armstrong, who is a crab fisherman.His wife, Lynn, was standing on the kitchen cabinets, the only place where "your head would touch the roof," he said. Only their heads were above the water.After hours of waiting in the flooded house for rescue, Armstrong's wife succumbed to hypothermia and slipped under the water."And then I kept with her, and she just drowned on me," he said, breaking down.When the storm finally released its devastating hold on the Bahamas on Tuesday, seven people were known to have died -- all on the Abaco islands, east of Grand Bahama -- and officials fear the death toll will rise sharply as more accounts like Armstrong's come to light."She was gone so quickly," Armstrong said as he waited for his wife's body to be recovered.Armstrong said he then "took a chance" and swam outside the house to his boat, which was moored nearby."I saw my boat was still there, and I swam," he said.Armstrong said he'd lived in Freeport for 58 years and had "battled many a hurricane," but had never seen flooding like this."Everything I own is gone," Armstrong said. "Every single thing." 1507

At least eight Walmart locations have received threats over the past week after deadly shootings at two stores in recent weeks, law enforcement agencies said.The threats follow a horrific massacre at a Walmart in Texas last weekend and a deadly shooting at a store in Mississippi late last month.In Florida, Richard D. Clayton, 26, was arrested after he allegedly posted a threat on Facebook that he was about to have his gun returned and people should stay away from Walmart.He was detained Friday after an investigation by various agencies, including the FBI, the Winter Park Police Department and the Florida Department of Law Enforcement.He allegedly made a threat Tuesday on a Facebook post stating, "3 more days of probation left then I get my AR-15 back. Don't go to Walmart next week," the Florida Department of Law Enforcement said.He remains in custody on ,000 bond, according to 905
