Health officials agree coronavirus cases are going to increase this winter as Americans head indoors to stay warm and closed windows will lead to less ventilation.But what about the dry air inside and outside this time of year, could a humidifier help slow the spread of coronavirus? That is still being debated.A study released this month seems to suggest increasing humidity plays a role in decreasing cases of coronavirus. The study, which has not been peer-reviewed yet, was shared on medRxiv.This study was based on the premise that previous studies have shown that falling humidity is tied to increased transmission rates of other respiratory diseases, like the flu. Researchers looked at more than 3,000 counties around the country and their humidity levels between March and September 2020.The team says they found increasing humidity levels had a negative impact on new cases of COVID-19 in most regions. In two of the regions that showed the highest effect, a 1 g/m3 increase in absolute humidity resulted in a 0.21 and 0.15 decrease in COVID-19 cases.However, there are also studies that show the humidity level had little to no effect on the spread of COVID-19.A study released in early November found the weather had “virtually no impact” on the spread. Instead, they said human behavior changes during weather fluctuations, outside during warmer weather and heading indoor during cold weather, had a large impact.What health and science experts seem to agree on is that the air does get drier in the winter from both the cold air outside and heated air inside. And that without proper ventilation, any coronavirus droplets in a space could linger longer and become more concentrated.This dry air can also cause nasal passages to dry out, which means noses could have less protective mucus. Some doctors have said whether or not the science completely proves humid air can help slow the spread of coronavirus, having more humidity in the air can make this winter more comfortable and noses more able to protect against all virus. 2051

Here's what's making headlines in the political world on Saturday, November 24 2018:Trump administration asks SCOTUS to hear transgender ban- In yet another aggressive attempt to bypass federal appeals courts, the Trump administration asked the Supreme Court on Friday to hear a challenge to President Donald Trump's policy that bars most transgender individuals from military service.The policy, first announced by the President in July 2017 via Twitter and later officially released by Secretary of Defense James Mattis, blocks individuals who suffer from a condition known as gender dysphoria from serving with limited exceptions. It also specifies that individuals without the condition can serve but only if they do so according to the sex they were assigned at birth.District courts across the country have so far blocked the policy from going into effect. The 9th Circuit Court of Appeals heard arguments in one challenge earlier this fall and the DC Circuit will hear arguments in early December. Read more 1022

GARDEN GROVE, Calif. (AP) — The man who killed four people and wounded two others in random stabbings across two Southern California cities is a gang member with a violent criminal record who had served time in prison, authorities said Thursday.Zachary Castaneda "could have injured or killed many other people" had he not been arrested Wednesday while carrying out attacks and robberies during the two-hour wave of violence that began in Garden Grove, the city's police Chief Tom DaRe said.It wasn't immediately known if Castaneda, 33, had a lawyer who could speak on his behalf. He was scheduled to be arraigned Friday.Castaneda was taken into custody when he walked out of a convenience store in the neighboring city of Santa Ana, dropping a knife and a gun he had taken from a security guard he had just killed, police said. The suspect was covered in blood, DaRe said.Castaneda was kept in restraints as detectives tried to interview him, the chief said at a press conference."He remained violent with us through the night," DaRe said. "He never told us why he did this."Castaneda has a conviction for possession of meth for sale while armed with an assault rifle, DaRe said. Investigators were still putting together his entire criminal history, he said. Officials didn't specify what crimes sent Castaneda to prison or when he was released.The violence appeared to be random and the only known motive seem to be "robbery, hate, homicide," Garden Grove police Lt. Carl Whitney told reporters.Whitney said police had previously gone to Castaneda's Garden Grove apartment to deal with a child custody issue. The suspect's mother had been living with him and had once asked police how she could evict her son, he said.The attacker and four of the victims were described as Hispanic, while two victims were described as white, police said in a statement. Initially, all had been described as Hispanic. There was no indication this was a hate crime, DaRe said.The two people who were wounded were expected to survive.One of the dead was identified by his son as a hard-working immigrant originally from Romania.Erwin Hauprich said in a telephone interview that his father, Helmuth Hauprich, 62, called him Wednesday afternoon and told him his Garden Grove apartment had been burglarized. The father said his passport, green card, sword collection and even a dining table were taken.Erwin Hauprich said his father never called back and he went to check on him after hearing there had been a stabbing at the complex.A police officer told him that Helmuth Hauprich had been taken to the hospital, where he died, the son said. He said he was told his father's roommate was killed in the apartment.A body was removed from the complex by stretcher Thursday.Erwin Hauprich said his father left Romania first for Germany and then the United States more than two decades ago. He said his father worked on an assembly line and lived in the complex for years.He said Helmuth Hauprich was a down-to-earth man who strove to make a life for his family.Police said surveillance cameras caught some of the carnage."We have video showing him attacking these people and conducting these murders," Whitney said.Whitney said the man lived in a Garden Grove apartment building where he stabbed two men during some kind of confrontation. One man died inside and the other at a hospital.Whitney said a bakery also was robbed.The bakery owner, Dona Beltran, said she was sitting in her car charging her cellphone when she saw a tattooed man get out of a Mercedes and go inside the business. Beltran, 45, followed him inside to offer help, but kept quiet when she saw him trying to open the cash register.She then ran out of the shop and yelled she was being robbed before taking refuge in a nearby dental office, she said. He ended up taking the entire register with him, which had about 0, she said."I saved myself because I was in the car," she said in Spanish on Thursday. "Thank God I am alive."The man also robbed an insurance business, where a 54-year-old employee was stabbed several times and was expected to survive.The woman "was very brave," Whitney said. "She fought as best she could."An alarm company saw the robbery on a live television feed and called police.The man fled with cash and also robbed a check-cashing business next door, the lieutenant said.Afterward, the attacker drove up to a Chevron station, where he attacked a man pumping gas "for no reason," Whitney said.The man was stabbed in the back and "his nose was nearly severed off his face," the lieutenant said.Undercover detectives tracked the suspect's silver Mercedes to the parking lot of the 7-Eleven in Santa Ana and within a minute the man emerged from the store, carrying a large knife and a gun that he had cut from the belt of a security guard after stabbing him, Whitney said.Police ordered the man to drop his weapons and he complied and was arrested.Police then learned that a male employee of a nearby Subway restaurant also had been fatally stabbed during a robbery, Whitney said.The brutal and puzzling attack came just days after a pair of mass shootings in Texas and Ohio left 31 people dead and stunned the nation.___Associated Press reporters Robert Jablon, John Antczak and Christopher Weber contributed from Los Angeles 5309

HEALY, Alaska – The book and movie “Into the Wild” profiled Christopher McCandless, a young man who left his family to connect with nature in Alaska in the 1990s.The old bus he lived in before he died has attracted sightseers that have risked their lives to see it in a remote area. Soon, anyone will be able to see it without a dangerous hike.“Maybe not everybody would have done exactly what he did, but the fact that he did that is very attractive in the hearts of a lot of different people,” said Patrick Drunkenmiller, Director of the University of Alaska Museum of the North.Drunkenmiller says the state is far too familiar with McCandless’ story.McCandless hiked his way through the interior to live off the land. That’s when he found the bus, Fairbanks Bus 142, and used it as shelter for 114 days, according to Alaska historian Angela Linn.“That story and the resulting tragedy that he wasn’t able to make it out of there, it’s kind of one of those classic stories that we’re trying to understand on the grand Alaskan scale, of course, because this happens to a lot of people,” said Linn. “Disappearing in the Alaskan wilderness happens to a lot of people.”McCandless died after not being able to cross back through a river. He ate a poisonous plant and died in the bus after leaving a farewell letter. Decades later, people from all over the world have traveled to Alaska to find Bus 142.“So, sure, people thought let’s go check this out, unfortunately the Teklanika River was the same barrier to many of those visitors as Christopher McCandless for trying to leave,” said Drunkenmiller.“Unfortunately, two people died, lots of other people had to be rescued, because they weren’t prepared to either go across one way or come back the other way,” said Linn.With countless rescues and two deaths, the most recent one last year, the state finally decided to remove the bus in June.“A lot of people have a lot of strong feelings about DNR removing the bus from that location. They felt like it acted as a symbol of that place and that story and that feeling, that emotion that he was trying to connect with," sid Linn.“The owners of the bus, the Alaska Department of Natural Resources, said enough is enough, this is a real menace to public safety,” said Drunkenmiller.The famous bus is now at an undisclosed location. It’s in the process of making its way to its new home, the University of Alaska’s museum.While McCandless’ story can be considered a controversial, it is a storied part of Alaska’s history.“This is part of the craziness that is Alaska, this wildness of Alaska, that 20 miles off the highway, that this kind of thing can happen,” said Linn. 2673
