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

The United States could see an increase in immigrants coming to the country after Hurricanes Irma and Harvey, according to new research from the University of Michigan.According to the study, there are multiple reasons this happens, including migrants might find it easier to flee destruction in their own country.Another reason, according to U-M economists Dean Yang and Parag Mahajan, is they are able to secure green cards or legal permanent residency through their families already established in the country."When there's a bigger stock of previous migrants to the U.S., when someone in their home country is more likely to have a connection to some sort of migrant in the U.S., then the effect of hurricanes on migration is larger," Yang said.The researchers first studied the severity of a hurricane in a given country, using data from meteorological reports to estimate actual damage.Yang and Mahajan then analyzed restricted U.S. Census data from 159 counties over 25 years to see if America saw a rise in immigration following large storms in other countries.The largest effect came from Central America and the Caribbean."These regions get hit a lot by hurricanes that cause severe damage, and there are a lot of Central American and Caribbean immigrants in the U.S., so if you're looking for someone to sponsor you, you actually have that opportunity," Mahajan said.One example of that is Hurricane Cesar hitting Nicaragua in 1996. It caused food shortages, .5 million in damage, left 100,000 people homeless and killed 42. Yang and Mahajan found that in 1996 and 1997, there was a 50 percent increase in legal permanent residencies for Nicaraguans than in 1995."Much of this increase came from immediate relatives of U.S. citizens - parents, spouses and children," Mahajan added. "Repeated, similar responses like this in the data helped us conclude that networks of U.S. citizens from sending countries provide opportunities for family members to escape severe weather events." 2007

The U.S. Postal Service on Tuesday said it could not meet a federal judge’s order to sweep processing centers for undelivered mail-in ballots, arguing that doing so would disrupt its Election Day operations. U.S. District Judge Emmet G. Sullivan of Washington, D.C., gave the agency until Tuesday afternoon to search 27 facilities in several battleground areas for outstanding ballots and send out those votes immediately. In its response, the Postal Service said it had already conducted rounds of morning checks at all its processing hubs. Further, the agency said it has been performing daily reviews of all 220 facilities handling election mail and planned another sweep hours before polling places closed Tuesday. 726

The Trump Administration pushed through a million contract to study whether the active ingredient in Pepcid is an effective treatment for Covid-19. That contract is now under scrutiny after a government whistleblower accused a senior administration official of rushing the deal through without the scientific oversight necessary for such a large federal award. The Food and Drug Administration gave the clinical trial speedy approval even as a top agency official worried that daily injections of high doses of famotidine for already sick patients pushed the levels of what was considered safe “to the limits,” internal government emails show. And the doctors who initially pushed the Pepcid idea are locked in a battle for credit and sniping over allegations of scientific misconduct.The origins of the interest in famotidine are under dispute, but there were reports out of China that patients who took the drug survived the virus, while patients who took other heartburn medications were not surviving. Initial observational studies in the U.S. were promising, however scientists urged more research was needed. Meantime, the trial itself that was part of the million contract is on pause due to a shortage of hospitalized COVID-19 patients in New York, delaying it indefinitely. A vaccine or effective treatment could be available before the study is complete. 1380

The World Health Organization updated its guidelines on mask-wearing Tuesday, recommending that anyone over the age of 12 wear a mask indoor and outdoor and inside your home if it's ventilated poorly.The updated guidelines come as COVID-19 cases continue to sore in America. On Wednesday, 180,083 new cases were reported, according to data from Johns Hopkins University.According to the guidelines, in areas where COVID is spreading, WHO recommends that anyone over the age of 12 wear masks in shops, shared workplaces, and schools if they can't maintain a distance of more than 3-feet between others.They also recommend masks be worn when people visit your home if there's not adequate ventilation, or you can't be more than 3-feet or more from each other.The WHO said on top of wearing a mask, other precautions such as washing hands, avoiding touching your face, having adequate ventilation if indoors, testing, contact tracing, quarantine, and isolation should also be taken."Together, these measures are critical to prevent human-to-human transmission of COVID-19," WHO said.In areas of COVID-19 spread, the organization said healthcare workers should take part in "universal masking" in health care facilities, meaning they should wear an N95 respirator mask throughout their entire shift, including when caring for other patients.The advice applied to visitors, outpatients, and common areas such as cafeterias and staff rooms, but added administrative staff does not need to wear a mask if they are not exposed to patients.The organization also recommended that people who do vigorous physical activity should not wear masks, citing some associated risks, particularly asthma.For children, the WHO recommends children up to 5-years-old should not wear masks for source control. They added that children between the ages of 6 to 11-years-old should only wear masks if "a risk-based approach is applied.""Factors to be considered in the risk-based approach include intensity of COVID-19 transmission, child’s capacity to comply with the appropriate use of masks and availability of appropriate adult supervision, local social and cultural environment, and specific settings such as households with elderly relatives, or schools," the organization added in its guidelines. 2285
