The sudden and abrupt breakdown of the US Postal Service has unfolded in recent days as Democrats call for a funding boost ahead of this year’s presidential election.On Friday, the USPS announced a temporary price increase in some services from Oct. 18 until Dec. 27. The rate hike affects commercial services, as retail services are not affected.Meanwhile, the USPS has been removing mailboxes and processing machines. The machines and mailboxes are being removed across the country, according to local reports from a number of Scripps stations.On Friday, CNN and the Washington Post reported that a number of states have received letters from the Postal Service warning that they might not have the ability to ensure ballots are sent and returned in a timely manner. The warning comes as more Americans are expected to utilize mail-in voting due to the coronavirus pandemic.“The Postal Service is asking election officials and voters to realistically consider how the mail works,” Martha Johnson, a spokeswoman for the USPS, said in a statement to the Washington Post.Despite requesting a mail-in ballot himself for next week’s Florida primary, President Donald Trump has tried to sow doubt in recent weeks over the reliability of mail-in voting, claiming that the process is ripe with fraud. But there has been limited evidence to suggest his fears are founded.With the postal service facing financial troubles due to rising pension costs and decreasing usage, Trump said he would agree to funding the Postal Service, but would need some concessions from Democrats."Sure, if they gave us what we want. And it’s not what I want, it’s what the American people want," Trump said Friday. 1694

The United Kingdom says it will be the first to conduct COVID-19 vaccine human challenge trials.It's different than other vaccine studies. People will be deliberately infected with the virus, which speeds up the research process.Pending approval, the process will start in January at a London hospital. It will require about 90 healthy young adults between the ages of 18 and 30.The group 1 Day Sooner has recruited from all over the world, including 3,000 Britons.“If the vaccine works, then ideally, people don't get infected and if people do, then they will be closely monitored and treated, but because these are young and healthy people taking part in the trial, I think, researchers feel comfortable doing so because the risks of death are on par with something like kidney donation for people who are young and healthy,” said Abie Rohrig with 1 Day Sooner.Before researchers test the vaccine, they'll do a characterization study. That's where volunteers are infected by getting a vaccine to determine the right amount of virus to give during the trial.Because of the risk, 1 Day Sooner is advocating for the entire process to be made public.Results could come in May. Even though that's likely after other COVID-19 vaccines are licensed, it's still important because we need billions of doses and because of the unique data human challenge trials provide.“Researchers can understand how the virus works in the human body. They can understand the biological markers of immunity. In fact, much of our understanding of other types of coronaviruses come from challenge studies that were conducted in the 1960s in Britain,” said Rohrig.Human challenge volunteers are paid and monitored for at least a year after. 1722

The world's biggest COVID-19 vaccine test got underway Monday with the first of 30,000 planned volunteers. The experimental vaccine is made by the National Institutes of Health and Moderna Inc. It's one of several candidates in the final stretch of the global vaccine race. Officials are seeking to find out whether more people who get dummy shots become infected than those given two doses of the real vaccine. The U.S. government plans separate huge studies of several leading vaccine candidates through fall, each in hot spots where the virus still is spreading.Dr. Anthony Fauci and other Trump administration officials have said that the company is already producing millions of doses of the vaccine in the event that it receives Emergency Use Authorization from the FDA following the trial. Fauci remains cautiously optimistic that a vaccine could be available by January of next year — though it's unclear how long it would take for a vaccine to be available for all Americans who want it. 1004

  

The US Forest Service hopes families will want to end 2020 with a live tree, preferably one cut from a national forest.Cutting down a Christmas tree is a tradition for many, and a healthy tradition for the forests as smaller trees get thinned out.“By cutting your own tree, you take an active part in managing your national forests,” according to the US Forest Service webpage.Tree hunters should look for an area of tightly-knit, dense trees and pick one from there. This will in turn give the surrounding trees more space to grow, Hillary Santanez, recreation event coordinator with the White River National Forest, explained to KMGH.Thinning the forests in this fashion reduces competition for resources and nutrients so the other trees can grow stronger and healthier, Santanez said. It also helps the trees handle stressful environmental situations, such as drought. In addition, thinning dense forests can help with wildfire mitigation.Families who have a fourth or fifth grader can get a free permit from the Every Kid Outdoors initiative through the US Forest Service. Otherwise, permits to cut down a tree in a national forest run to depending on the park. Permits are required. All permit sales are online for 2020, along with maps, how to select a tree, guidance for cutting it down and safety reminders. Like, dressing for the cold, possibly dark and snowy forest conditions. The different parks have different rules about where a Christmas tree can be cut down from, usually it has to be about 200 feet from roads and campgrounds."You want to make sure that you're not trespassing on private property, so going onto our website and downloading a map is essential so that you can make sure that you're staying on forest land because a lot of the forest land, especially in the Front Range area, is really adjacent to private property, and you have to make sure that you're following the law while you're up there," Pike and San Isabel National Forests and Cimarron and Comanche National Grasslands Public Affairs Officer Crystal Young told KOAA News.There are height and trunk size requirements as well to make sure tree hunters are taking the smaller trees to help thin out forests.

The stomach-churning market scare continues.The Dow tumbled 546 points, or 2.1%, on Thursday following another rollercoaster session. The index briefly turned positive during morning trading before succumbing to heavy selling pressure. At one point the Dow was down 699 points. The Dow has shed 1,378 points over the past two days.The mood on Wall Street was only slightly calmer than Wednesday's 832-point nosedive.The S&P 500 closed down 2.1%, notching its sixth-straight losing session. It's the longest slump for the broad index since just prior to President Donald Trump's election more than two years ago.The Nasdaq briefly tumbled into a correction, signaling a 10% decline from previous highs. But the index climbed out of correction territory and closed down 1.3%.All three major indexes have lost more than 5% this week. That hasn't happened since March."This kind of washout doesn't get accomplished in a day. Even though yesterday felt traumatic, it tends to be a three-day process," said Art Hogan, chief market strategist at B. Riley FBR.The VIX volatility index touched its highest level since February.One positive is that unlike on Wednesday, the market did not close on the lows of the day. The rebound was helped by fresh?reports that President Donald Trump and Chinese leader Xi Jinping have agreed to meet next month at the G-20 summit. Such a meeting could ease fears that the US-China trade war will hurt corporate profits and slow the US economy.Tech stocks have come under fire because they are some of the riskiest and most expensive parts of the market. Investors fear how these momentum names will hold up in a downturn, particularly as interest rates spike. A proxy for the tech sector had its sharpest plunge in seven years on Wednesday."Halloween started early this month for investors," Ed Yardeni, president of investment advisory firm Yardeni Research, wrote to clients.The afternoon sell-off comes even though a new report showed that consumer prices rose less than expected in September.Stocks have turned sharply south in large part because investors are concerned about rising interest rates. As the Federal Reserve raises rates to prevent runaway inflation, investors have been getting out of bonds, driving down their price and driving up their yields. Suddenly, the return on bonds has become competitive with some stocks — particularly risky tech stocks.Rising interest rates also increase borrowing costs for households and businesses, eating into corporate profits. 2551
