Why are stocks falling again? President Donald Trump says it's because Democrats are gearing up to use their impending control of the House of Representatives to investigate him. As always, when it comes to the markets, the real answer is complicated.The Dow fell by more than 600 points on Monday, dragged down by investors' concerns about the tech sector and the rising dollar. The Nasdaq fell 2% and the broader S&P 500 fell 1.2%.Apple (AAPL) fell 5% after supplier Lumentum cut its earnings and sales forecast because of weak demand, and JPMorgan cut its target price on Apple's stock. That weighed on other technology stocks, including Amazon (AMZN) and Tesla (TSLA) -- down 4% -- as well as Facebook, which fell 3%. Google (GOOGL), Netflix (NFLX) and Microsoft (MSFT) were all down more than 2%.The strong dollar also weighed on stocks. The US currency surged to a 16-month high because investors fear the European economy could stall if no Brexit deal is reached this week. Prospects of another rate hike from the Fed next month have also helped lift the dollar. The rising dollar is a signal of a strong economy, but it hurts sales and profits for American companies that do business overseas.Though Trump blamed Democrats for the drop, the Dow had actually bounced back since the midterms, rising last week in its best showing since March. Wall Street tends to like stagnation in Washington, so investors are actually just fine with Democrats taking the House.As for what Trump termed the "prospect of presidential harassment," there is not much evidence the stock market will bat an eye if Democratic leaders in the House begin investigations into the Trump administration. Stocks rose before, during and after President Bill Clinton's impeachment. 1800

While public health experts have acknowledged the risk for healthy athletes when becoming infected with the coronavirus has been rather low, lingering questions have remained on if the virus causes long-term cardiac damage.Doctors from the Sports and Exercise Cardiology Section of the American College of Cardiology released some of their preliminary findings on the effect the coronavirus has on athletes’ hearts.With college football fully resuming this week with the return of the Pac-12, and college basketball slated to get underway next month, sports are beginning to return to normal amid the pandemic. While some athletes are being frequently tested for the virus, testing alone has not stopped team-wide outbreaks from occurring.Despite there being some limited evidence that the virus causes cardiac injury to athletes, researchers wrote in JAMA that heart damage alone should not be the primary reason to postpone athletic competitions amid the pandemic.“While concerns about the implications of cardiac injury attributable to COVID-19 infection deserve further study, they should not constitute a primary justification for the cancellation or postponement of sports,” the researchers wrote.“Rather than canceling sports because of unsubstantiated concerns about cardiac safety based on limited data of unestablished clinical relevance, this decision should be driven by the need to limit viral spread,” researchers added. “With uncontrolled community transmission, we share concerns with public health officials about risks of increased disease transmission attributable to the resumption of organized sports. Accordingly, the decision to proceed with or delay organized sports should be based on community disease prevalence, coupled with the availability of resources that can be responsibly allocated to identify and prevent new infections among athletes.”The researchers said that initial findings have produced only a handful of cases of cardiac injury, but stressed that more research is needed.“Reports of presumptive myocarditis among several athletes with high profiles have magnified concerns about COVID-19 CV sequelae in athletes,” the researchers wrote. “Our combined experience suggests that most athletes with COVID-19 are asymptomatic to mildly ill, and to date, (return to play) risk stratification has yielded few cases of relevant cardiac pathology. However, we underscore that these observations may not reflect the true prevalence and attendant prognosis of COVID-19 CV involvement in athletes.”As far as what players should do following their 10-day isolation period, assuming they minimal coronavirus symptoms?“We do not advocate for (cardiovascular) risk stratification among athletes who remain completely asymptomatic with prior COVID-19 infection, following completion of US Centers for Disease Control and Prevention (CDC) guided self-isolation,” the researchers wrote. “Given the current lack of published data, consideration of comprehensive screening for this population could be reasonable if it is based on research and data collection.”The Big Ten, which was among several leagues that held out on playing at the start of the football season, requires athletes to undergo cardiovascular screening following a positive coronavirus test. Part of what concerned the Big Ten initially was reports that a number of its athletes who tested positive for the virus had shown myocarditis symptoms.According to the National Institutes of Health, myocarditis is an acute injury that “leads to myocyte damage, which in turn activates the innate and humeral immune system, leading to severe inflammation.”“All COVID-19 positive student-athletes will have to undergo comprehensive cardiac testing to include labs and biomarkers, ECG, Echocardiogram and a Cardiac MRI,” the Big Ten said in a statement. “Following cardiac evaluation, student-athletes must receive clearance from a cardiologist designated by the university for the primary purpose of cardiac clearance for COVID-19 positive student-athletes. The earliest a student-athlete can return to game competition is 21 days following a COVID-19 positive diagnosis. “In addition to the medical protocols approved, the 14 Big Ten institutions will establish a cardiac registry in an effort to examine the effects on COVID-19 positive student-athletes. The registry and associated data will attempt to answer many of the unknowns regarding the cardiac manifestations in COVID-19 positive elite athletes.”To read an abstract of the research, click here. 4546

When Nolan Davis called his community to march for Black Lives Matter, hundreds turned up for the cause. On Saturday, he led demonstrators from a park in his hometown of Kirkwood, Missouri to the town's city center, leading chants along the way.But Nolan's protest looked a bit different than others that have taken place across the country in recent weeks — because almost all the participants were children.Nolan, 8, helped organize the protest along with his mother, Kristin Davis. According to CNN, he was inspired to lead his own protest after the two attended a few other rallies in the St. Louis area.Nolan and his mother designed a flyer to get the word out about the protest and shared it on Facebook. Nolan told CNN that he believed that about 50 people would show up to his event. But when he arrived at the park on Saturday morning, there were about 700 people ready to support his movement.According to CNN, Kristin Davis, who is white, adopted Nolan and his 5-year-old sister, Caroline, who are both Black. Their mother says that while she could never understand what her children go through, she's tried to have regular conversations about racism with them to keep them safe."We're preparing them for when they're older and taller and bigger. When they're not going to be perceived as cute little kids anymore," Kristin Davis told CNN.During the protest, Nolan held a sign that read "Kids Can Make a Change," according to photos from St. Louis-Post Dispatch. 1481

When Mollie Tibbetts went for a jog and never returned, her death realized the worst fears of many runners, especially women, who lace up their sneakers unsure of what they may face on the road.But runners across the country aren't letting fears of a similar situation stop them. Instead, they are dedicating their runs to the 20-year-old University of Iowa student and sharing hopeful messages on social media tagged #MilesforMollie."This run is for you Mollie. We are with you. We will not allow fear to stop us from doing the things we love," University of Iowa alumna Sarah Hemann Bishop posted on Twitter. She included a picture of her sneakers, which have "Miles for Mollie" written on the side.A funeral was held Sunday for Tibbetts in her hometown of Brooklyn, Iowa, where she was last seen alive on July 18. Police say Cristhian Bahena Rivera told them he saw Tibbetts running and "pursued her in his vehicle." Later, he parked the car and started running near her. He is charged with first-degree murder."I find so much joy in running and as a female, I know I have to run with an added sense of caution, especially when running alone. It is unfair," Bishop told CNN. "I joined #milesformollie to show that we are not afraid. Mollie inspires us to be strong and brave." 1287
