The Dow Jones Industrial Average sank more than 900 points on Wednesday , mirroring drops in European markets.The Dow Jones had its worst day since June 11. U.S. stocks recorded historic losses in February and March, fueled by shutdown measures to prevent the spread of COVID-19. However, since the shutdowns, U.S. markets have recovered to nearly the levels that were at prior to the pandemic.Despite stock recoveries, other important economic measuring sticks like unemployment remain historically high.Recent losses come as COVID-19 cases spike again across the country. Health experts warn that the U.S. is at a perilous point in the pandemic with rising hospital and death rates ahead of winter months. 715

The FDA issued an emergency use authorization for a saliva-based coronavirus test that has been used to identify COVID-19 cases by NBA players. Leading officials are calling the test a “game-changer.”The SalivaDirect test is said to be both rapid in its findings, and inexpensive. Yale said it doesn’t hope to commercialize the test, rather increase the country’s testing capabilities.“Widespread testing is critical for our control efforts. We simplified the test so that it only costs a couple of dollars for reagents, and we expect that labs will only charge about per sample. If cheap alternatives like SalivaDirect can be implemented across the country, we may finally get a handle on this pandemic, even before a vaccine,” said Nathan Grubaugh, a scientist with Yale Public Health.Yale scientists say that the nasal samples are less invasive than swabbing, but are equally as accurate.“This is a huge step forward to make testing more accessible,” said Chantal Vogels, a Yale postdoctoral fellow. “This started off as an idea in our lab soon after we found saliva to be a promising sample type of the detection of SARS-CoV-2, and now it has the potential to be used on a large scale to help protect public health. We are delighted to make this contribution to the fight against coronavirus.”The test earned praise from members of the White House coronavirus task force.“The SalivaDirect test for rapid detection of SARS-CoV-2 is yet another testing innovation game-changer that will reduce the demand for scarce testing resources,” said Assistant Secretary for Health and COVID-19 Testing Coordinator Admiral Brett P. Giroir, M.D. “Our current national expansion of COVID-19 testing is only possible because of FDA’s technical expertise and reduction of regulatory barriers, coupled with the private sector’s ability to innovate and their high motivation to answer complex challenges posed by this pandemic.” 1926

The coronavirus pandemic may have started earlier than previously thought, according to scientists from the CDC.A study from government scientists published November 30 appears to confirm what some health experts have suggested, patients infected with COVID-19 were in the US before the beginning of 2020.“The findings of this report suggest that SARS-CoV-2 infections may have been present in the U.S. in December 2019, earlier than previously recognized. These findings also highlight the value of blood donations as a source for conducting SARS-CoV-2 surveillance studies,” the report states.The first officially documented case of COVID-19 in the US was reported on January 19, a person who had returned to the US after traveling from China.The World Health Organization was alerted to the novel coronavirus by officials in Wuhan, China on December 31, 2019. The CDC researchers say further reports have identified a patient in Wuhan with COVID-19 symptoms as early as December 1, 2019.The study looked at more than 7,000 routine blood donation samples taken by the American Red Cross from people in nine states between December 13, 2019 and January 17, 2020.They found COVID-19 antibodies in 106 samples, mostly from the states of California, Oregon and Washington, from blood collected between December 13-16, 2019. Other samples that indicated COVID-19 antibodies were from Connecticut, Iowa, Massachusetts, Michigan, Rhode Island, and Wisconsin taken in early January 2020.“The presence of these serum antibodies indicate that isolated SARS-CoV-2 infections may have occurred in the western portion of the United States earlier than previously recognized or that a small portion of the population may have pre-existing antibodies that bind SARS-CoV-2,” the report states.Scientists acknowledge that patients presenting with what is now known as COVID-19 symptoms before mid-January would likely not have had clinical samples taken or kept because of how new the virus was. Therefore, the CDC used the existing repository collected by the American Red Cross during their routine blood donation process.“These specimens were previously archived for potential future studies to identify emerging transfusion-transmissible infections but were re-purposed for the present study,” researchers stated.Researchers caution that these results are subject to limitations. Although they detected antibodies, that does not mean they are “true positive” COVID-19 tests. In order to get a true positive, a different test would need to be a run. 2545

The entertainment world is still reeling from the loss of Chadwick Boseman, who died on Friday at the age of 43. Boseman had reportedly been privately fighting colon cancer since 2016, meaning some of his most iconic roles — including those in films like Black Panther, Marshall and 21 Bridges — were likely filmed between grueling chemo treatments.In the face of such an insurmountable loss, doctors and medical professionals hope that Boseman's cancer battle can shine a light on the dangers of colon cancer in young and middle-aged people and encourage them to undergo annual screenings.According to the Centers for Disease Control and Prevention, colon cancer is currently the second-leading cause of cancer deaths in the United States. In 2017, more than 50,000 people died of the disease.And while colon cancer is most common in people 50 years and older, researchers say cases among younger people are on the rise.Researchers say that doctors have been able to catch the disease early in older people because of a push for increased screenings, but they're still at a loss for why the disease is increasing in young people — though rising rates of obesity may be a factor.Furthermore, Boseman's death is highlighting the rates of colon cancer in Black Americans — according to the American Cancer Society, Black people have the highest rates of colorectal cancer of any racial or ethnic group in the U.S.But what are the symptoms of the disease?According to the American Cancer Society, colon cancer typically presents with:Change of bowel habitsFeeling the need to go, but not feeling relief afterRectal bleeding with bright red bloodBlood in the stool making it look dark brown or blackCramping or abdominal painWeakness or fatigueUnintended weight lossWhile those symptoms don't necessarily guarantee a cancer diagnosis, the American Cancer Society recommends anyone with those symptoms visit a doctor.The Mayo Clinic adds that the following could leave a person with a higher risk of colon cancer:Old age (50 and above)Race factors (Black men are 24% more likely to develop colon cancer than white men, and Black men die 47% more likely to die of the disease than white men)History of colon tumors or polypsInflammatory intestinal conditions, like ulcerative colitis or Chron's diseaseFamily history of colon cancerA diet low in fiber and high in fatSedentary lifestyleDiabetesObesitySmoking/alcohol useHistory of radiation treatments in the abdomen 2468

The Church of Jesus Christ of Latter-day Saints is embarking on a rebranding effort of sorts.The church, commonly referred to as the Mormons, really wants people to stop using that word. It also wants people to stop using LDS as an abbreviation. From now on, it prefers that people use the church's full name, and when a shortened reference is needed, to just use "the Church" or "Church of Jesus Christ."These preferences are contained in a new style guide that the Church of Jesus Christ of Latter-day Saints released Thursday. It states that while "the term 'Mormon Church' has long been publicly applied to the Church as a nickname, it is not an authorized title, and the Church discourages its use." It also asks that the term "Mormons" not be used in references to members.Also out: the word "Mormonism," which the style guide states is an "inaccurate" word to use to describe the "doctrine, culture and lifestyle unique to The Church of Jesus Christ of Latter-day Saints." But the word Mormon is fine to use in proper names, like the Book of Mormon, or in historical expressions like the Mormon Trail. 1126
