CHICAGO, Ill. – A study published this month suggests that by lessening the amount of virus you take in by putting on a mask, you may also lessen the likelihood of getting severely sick if you contract COVID-19.As the race to a safe and effective coronavirus vaccine heats up, new research about masks is changing the narrative on their importance.Last week, CDC Director Dr. Robert Redfield called face masks the most “powerful public health tool we have.”“I might even go so far as to say that this face mask is more guaranteed to protect me against COVID than when I take a COVID vaccine,” said Dr. Redfield.It was a stark change from CDC messaging early on in the pandemic that face coverings would most likely only protect those around you.“That was because there was a lot of data at that time that you can shed the virus at high rates from your nose and mouth even when you feel well,” said Dr. Monica Gandhi, an infectious disease doctor and professor of medicine at the University of California – San Francisco.She co-authored newly published research in the New England Journal of Medicine that theorizes that not only do masks protect the wearer but they may even reduce the severity of the coronavirus when someone gets infected.“We realized that we should be messaging more strongly masks protect you as the wearer and protects others,” said Dr. Gandhi.It theoretically works much like the early days of vaccines that used small amounts of viruses to illicit an immune response in the body. So, by wearing a mask, you are only exposed to lesser amounts of the virus, if any, potentially building up a sort of immunity.“The more virus you get inside, the sicker you are, the less virus you have, the less sick you are. This is called a dose response and it's true of many infections,” said Dr. Emily Landon, an epidemiologist and infectious disease specialist at University of Chicago Medicine.Gandhi says the theory has already been studied and proven in animals.“There was a hamster study that looked at the COVID-19 virus and the more that the hamsters were given, the more sick they got,” she said.Dr. Gandhi says it could also explain the why according to the CDC, 40% of coronavirus patients are asymptomatic.“Countries that mask well have lower rates of severe illness than countries that don't mask well. So, putting it all together, this is our hypothesis.”And while the research is still theoretical, if it bears out, experts say universal mask-wearing could drive up the proportion of people who get less sick from the virus if they do contract it. 2579

CAMDEN, N.J. (AP) — A gunman opened fire on two New Jersey police officers while they were sitting in their vehicle at a red light Tuesday night, wounding them in what authorities are calling an ambush attack.At least one suspect opened fire on the plainclothes detectives in Camden, which is located just across the Delaware River from Philadelphia, said Camden County Police Chief J. Scott Thomson."The information we have thus far is that they were essentially ambushed," Thomson told reporters at a late night news conference. "A male walked up and began opening fire. We have anywhere between 10 and 25 rounds that were fired at the officers."One of the detectives was able to return fire, Thomson said, but it was not immediately clear if anyone else was shot. Thomson said his department was in communication with hospitals in the region.The detectives were taken to an area hospital and are expected to survive."At this point in time our officers have non-life-threatening injuries but not for the grace of God quite frankly," Thomson said. "The amount of rounds that were fired at close range and particularly through the windshield."Police continue to search for the suspect or suspects involved in the "unprovoked" attack."Maybe they did know they were police officers and that's the reason why they did it. Maybe they thought they were somebody else. We'll find that out as the investigation unfolds," Thomson said.The shooting occurred on National Night Out, an event designed to bring local police and the communities they serve together. 1560

CHICAGO -- One sector of the economy that skyrocketed as the pandemic hit is now seeing global shortages. Demand for bikes is nearing all-time highs. And if you’re in the market for a new two-wheeler, it may be months before you can wrap your fingers around some handlebars.Bicycles seem to be everywhere, unless you’re trying to buy one.At Edgebrook Cycle & Sport in Chicago, bikes have become a hot commodity during the pandemic.“It has been off the charts. It's unprecedented,” said owner Jim Kirsten.So much so that there’s a critical shortage, not just in the Windy City, but everywhere.“We have about 10% of our usual inventory and our service work which you see kind of surrounding me here is about 300% where it normally is,” said Kirsten.In fact, bike racks at retail giants like Walmart, Target and Dick’s Sport Goods are almost completely bare.Online vendors like Torrance, California-based Sixthreezero say demand for their bikes has jumped 800%. They’ve had to triple their staff to handle the increased interest.April sales for traditional bikes, indoor bikes, and other accessories grew by 75% compared to the same time last year and reached billion for the first time in a single month.Industry experts say commuters abandoning public transportation, gym closures and the search for socially distanced recreation created a perfect storm.Today’s bike boom, they say, is one not seen since the oil crisis of the early 1970s.“Mid to low price bicycles are just wiped out across the country,” said Jay Townley, a consultant with Human Powered Solutions. Townley spent much of his 60-year career at Schwinn and as president of Giant Bicycle Company.“Along with new bike sales, bicycle repair has skyrocketed. There are a lot of shops if you call around the shops in your area, you'll find a lot of them are weeks out for repair,” he said.Townley says the U.S. bicycle market is import dependent with more than 90% coming from China.Punitive trade tariffs, supply chain disruptions and lackluster 2019 sales caught manufacturers off guard and forecasts didn’t predict the increased demand accelerated by the pandemic.“Now, we're in a phase where we're trying to get that pipeline to replenish those inventories and that's going to be extremely difficult as we go forward,” said Townley.It could be late fall before supply catches up to demand. In the meantime, buying used may be the best way to pedal forward. 2431

CARLSBAD, Calif. (KGTV) - The family of an 18-year-old man shot and killed in Carlsbad last July says they’re upset with the sentence handed down for the man who supplied the gun in the shooting.Connor Mangseth is described by family as someone who lived life to the fullest, inspiring those around him to do the same. His mother said he would befriend anyone, no matter their background, and that’s what led to his death this year. On July 23, Connor went to the home of a friend and 19-year-old Gerardo Gonzales, another friend, was also present. Gonzalez was already facing felony charges for another crime and was out on bail.RELATED: Teen girl, young man arrested in Carlsbad shooting deathGerardo had a gun, which he gave to a 16-year-old female who was also with them. She said she thought it was empty when she pulled the trigger, but there was a bullet inside, which struck and killed Connor. Connor’s sister said it’s what happened next that deserves justice.“The worst part is the things that happened after that. It was that Gerardo Gonzales and this minor left to go hide the gun, they created a false story involving two other gunman and they spent 20 minutes doing this instead of anyone calling 911 or getting help,” said Sabrina Mangseth.Gerardo was charged with Accessory After the Fact and Child Endangerment. The Mangseth family said they are angry at the court system for how they handled these charges. Connor’s mother, Maureen, said they got silence from the District Attorney’s office, then she got a call saying Gerardo had taken a plea deal, something she was not told about ahead of time. She said she feels like the prosecutor was trying to rush the case rather than find justice, adding that to her knowledge, investigators have not completed their investigation and have more evidence to review.Sabrina started an online petition to bring awareness to the lack of communication during the case, gathering more than 6,000 signatures. A description in the petition describes Connor’s passion for life and the family’s desire for the court to take back the plea deal and wait to make any decisions until all evidence has been gathered.Ultimately, a second prosecutor was brought in to handle the case, but the guilty plea remained. Wednesday, Gerardo was sentenced to probation and up to one year in jail. Maureen said it doesn’t look likely that he’ll serve jail time. Sabrina did add that the second prosecutor did a better job of communicating with their family.“Gerardo Gonzales himself, in the trial, said Connor was my best friend and for him to do that to his best friend, I can’t even imagine what he would do to a stranger, someone else,” said Sabrina, worried about the lack of punishment for Gerardo.When asked for a response to the sentencing and plea deal, a spokesperson for the District Attorney’s office said: “This is obviously a tragic case and we have been in very close contact with the victim's family in recent weeks as we continue to seek justice for their loss. Two defendants were charged in connection with this murder. The defendant who is not the actual killer pleaded guilty to both counts he was charged with, including Accessory After the Fact and Child Endangerment, with an agreement from the People that there would be no opposition to a local jail sentence. The second defendant, a minor, remains charged with murder."The 16-year-old who pulled the trigger is facing murder charges and is next expected in court Nov. 9, 2020. 3495
