Hawaii warned residents and airplanes to stay away after a plume of ash from the Kilauea volcano rose 12,000 feet into the air.Since the Kilauea volcano erupted May 3, it's been one nightmare after another for residents in the southeast part of the Big Island.The US Geological Survey issued a red alert Tuesday, which means a major eruption is imminent or underway and ash could affect air trafficMichelle Coombs of the USGS described it as " very hazardous for aviation," and said her team isn't quite sure what caused Tuesday's slightly more intense ash emissions.US Geological Survey officials have said a phreatic eruption could happen at a crater at the top of the Kilauea volcano. It could send ash plumes as far as 12 miles from the summit crater, the Hawaiian Volcano Observatory said. 802

Hazards created by Hawaii's Kilauea volcano have spawned a lot of questions from the public. How long will this last? Is it safe to be on Big Island right now? Can I roast marshmallows?The US Geological Survey has been answering those questions on social media. Here's a look at some of them. The questions have been edited for clarity and brevity.Q: Is it safe to roast marshmallows over volcanic vents?USGS: Erm...we're going to have to say no, that's not safe. (Please don't try!) If the vent is emitting a lot of SO2 [sulfur dioxide] or H2S [hydrogen sulfide], they would taste BAD. And if you add sulfuric acid (in vog, for example) to sugar, you get a pretty spectacular reaction.Q: Is it safe to be in Hawaii right now?USGS: The eruption at Kilauea right now is impacting a small portion of the Big Island. Lava flows are active on the eastern tip of the island, in lower Puna, and Hawaii Volcanoes National Park is closed due to the small explosions occurring at Kilauea's summit. But the Island of Hawaii is made up of 5 volcanoes, and only Kilauea is erupting.Even if there were to be a change in activity at Kilauea, it would not impact Hilo or Kailua-Kona (the largest towns on the island), which are located on different volcanoes. The biggest impacts might be vog, but that has been a persistent issue on the island for decades. You can actually get real-time vog information at sites around the island from the Hawaii Department of Health at http://www.hiso2index.info/. 1493

GREEN BAY, Wisc. — A man was arrested for his seventh OWI after police say he threw stolen beer and meat out of his van with officers in pursuit. The Brown County Sheriff's Office received a call from a supermarket that Timothy Andrews, who was on their watch list for retail theft, was in the store. Authorities spotted Andrews inside a van in the parking lot and deputies say he claimed to have knives and gun when they approached him.Andrews refused to get out of the van, according to investigators, and sped away from the deputies, throwing stolen beer, meat and clothing out of the window during the high-speed chase. Authorities say the van lost control at least twice during the chase, as it weaved in and out of oncoming traffic on busy streets. "Pursuits are always a balance. You're always trying to balance public safety with the apprehension of the person. And in this case, this man was doing a lot of things," Brown County Sheriff's Capt. Dan Sandberg said. The van finally spun out of control and stopped on a residential street where the suspect was arrested. Andrews, 48, faces several charges in the case including 7th offense OWI, probation violation, obstructing an officer, shoplifting and retail theft.   1280

GRANDBY, Colo. — Imagine trying to outrun an inferno and three trees fall on the only road out. That's what Mike Darrah had to contend with Wednesday.The Trail Creek Estates homeowner said he received a pre-evacuation order Thursday, Oct. 15, so he and his wife drove up from Boulder County to pack a few things and put them in storage.He said he went back up Saturday to help neighbors with their horses and other belongings and stayed through Wednesday when it "started getting smoky."Soon, he could see flames moving through the entire valley. He will likely never forget the sound."It was like a freight train," he said, "the proverbial freight train, with the wind blowing."Darrah said he saw "swirling sparks" across the street, the entire area on fire."When I say on fire, it was from the ground all the way up to 90-foot pine trees. It was that fast," he said.Darrah told Denver7 he grabbed a few items from his house and started to drive out, only to be stopped by three Aspen trees which had blown over, blocking his way out.He got out the chain saw he said he keeps for such an occasion."I'm pulling and pulling trying to prime it. It would just sputter but it wouldn't get going," he said.Just as he was about the leave his truck and trailer behind and hoof it out of the neighborhood, a forest service employee drove up from the other side."He hopped out, and between the two of us, we were able to muscle those aspens, not off the road, but just enough to the side that I could get around them."Darrah said he doesn't know whether his house survived."We think we've lost it," he said.He told KMGH he has seen pictures of his neighbor's homes, several of which have burned to the ground, but he hasn't seen a photo of his house. He said the pictures were from a friend of a friend who knew a firefighter.He said it's stressful not knowing whether the house is still there, but he feels fortunate that he received advance notice of the fire."We got our family heirlooms and photos," he said.He said he's anxious to get back in to see his neighborhood for himself but understands the priority right now is fighting the fire and making sure everything is safe.He said he's also looking forward to the snow."It may put out some fire, but not enough to let people in," he said.This story was first reported by Lance Hernandez at KMGH in Denver, Colorado. 2371

Holidays will look different this year for many Americans, with dinners outside, social distancing, or passing on family gatherings altogether. But several companies developing rapid at-home COVID-19 tests are hopeful that won't be the case next year. The goal is to make inexpensive, easy-to-use COVID tests that can deliver results in minutes, just like a pregnancy test. "For people to feel comfortable to associate with friends or family, there needs to be a testing methodology ideally that can be performed at home," said Tony Lemmo, CEO of the manufacturing company BioDot.The company's technology is being used by over 70 manufacturers worldwide making COVID-19 antigen, antibody, and PCR tests. Their automated platforms dispense nanoliter/picoliter amounts of reagent onto the tests accurately and fast.Lemmo says just one of their systems can support the production of roughly 100 million COVID-19 tests per year, helping to make high-volume production possible.“We knew we were going to be called on by customers to manufacture more equipment to provide them the ability to manufacture more tests," said Lemmo. To meet customer demand, BioDot increased staffing and built a new facility, compressing production time from months to weeks. The FDA recently authorized the first rapid at-home test that can deliver results in 30 minutes, eliminating the need for a lab to test the sample. But the molecular single-use test will only be available to patients with a doctor's prescription who are suspected of being infected with COVID-19.Companies developing tests hope the FDA will soon authorize another at-home testing tool: the rapid antigen test.These inexpensive tests provide results within minutes, and companies developing them say millions could be sold without a doctor's referral.“From what we’re hearing, it’s really just a matter of possibly months before there’s at least sufficient data to be able to support an at-home use of a test like an antigen test," said Lemmo.Lemmo says if authorized by the FDA, manufacturers could make millions of these tests in a matter of months. But antigen tests are less accurate, and the FDA wants to ensure they'll be simple enough for people to use at home. There are also concerns over how the data will be reported to health authorities. “I think any at-home testing or massive rollout of a test into the communities needs to be done very carefully and with a lot of education around it," said Clinical Lab Director Melissa Miller. Dr. Miller is a professor of pathology and laboratory medicine at the University of North Carolina Chapel Hill and Medical Director for the Clinical Microbiology Lab for the Medical Center.She worries the inaccuracies of these tests could eventually lead the public to lose trust in all testing. “Even at 98 percent specificity, which is very, very high. That means you’re going to have a false positive two out of every 100. If you started testing a hundred million people, this is millions of people who have a false-positive test," said Dr. Miller. She says this could lead to healthy people isolating and missing work or school unnecessarily, and false-negative results could give people a false sense of security. “These rapid antigen tests were pushed out to skilled nursing facilities; this is a very high-risk patient population. This is actually where you want a very accurate test," said Dr. Miller. She says it’s unclear how well antigen tests detect the virus in asymptomatic patients but agrees more data is needed to figure that out.“It might make more sense for K-12 schools, or even college settings, where there’s less risk for a poor outcome if you have a false positive or a false negative," said Dr. Miller. But with a growing demand for convenient at-home testing, manufacturers are hopeful that in the months ahead, the FDA will soon open the door to new solutions. 3889
