The shape of the Earth is a spheroid, right? A YouGov study conducted this year says a third of people ages 18-24 aren’t sure our planet is round."If you believe we live on a globe, I know you're deceived." Welcome to the Flat Earth International Conference. “NASA has obviously lied to us on numerous occasions,” says Wendell, a conference attendee.Most of the people gathered at the conference held in Denver, Colorado believe Americans live on a lie. The flat Earth believers think pictures of the earth are fake and astronauts are actors. Social media sites like YouTube have made the flat earth theory more available in recent years. Some of those accounts have tens of thousands of followers."If you do trust your senses, you're seeing things different than what you're being fed," says Debra Auden, who traveled from Texas to the conference.Dr. Ka Chun Yu, the curator of space science at the Denver Museum of Nature and Science, says he was really surprised when he heard about the number of flat-earthers."We've known for over 2,000 years that the earth is more or less a sphere, a ball or a round shape."This is how the Greeks knew the earth was round. They realized that if you had sticks in the ground and you were able to measure their shadows on the same day, the lengths of the shadows would actually be different," Dr. Yu says.But to flat-earthers, science's facts are fiction. Flat Earth believers say an ice wall keeps us from falling off the surface.So, why do flat-earthers believe there would be such a lie about a round Earth? Some say conspiracy, while others turn to God. "You might not be convinced, but I encourage you to visit your local science museum or planetarium," Dr. Yu says. 1752

The recommended amount of sleep for adults is six to eight hours a night. Sleeping more than those hours is associated with an increased risk of death and cardiovascular diseases, says a global study published Wednesday in the European Heart Journal.Looking at data from 21 countries, across seven regions, the research team found that people sleeping more than the recommended upper limit of eight hours increased their risk of risk of major cardiovascular events, like stroke or heart failure, as well as death by up to 41%.But a possible reason for this could be that people have underlying conditions causing them to sleep longer, which in turn could raise the risk of cardiovascular disease or mortality, explain the authors of the study.The team, led by Chuangshi Wang, a Ph.D. student at McMaster and Peking Union Medical College in China, also identified a rising risk among daytime nappers."Daytime napping was associated with increased risks of major cardiovascular events and deaths in those with [more than] six hours of nighttime sleep but not in those sleeping [less than] 6 hours a night," Wang said.In those who underslept, "a daytime nap seemed to compensate for the lack of sleep at night and to mitigate the risks," Wang explained.Previous studies into this topic were mainly carried out in North America, Europe and Japan. The new study brings a global picture.But the findings are observational, meaning the cause of this association remains unknown."Even though the findings were very interesting they don't prove cause and effect," said Julie Ward, a senior cardiac nurse at the British Heart Foundation, who was not involved in the study.Having less sleep -- under six hours -- was also shown to increase these risks by 9%, compared with people who slept for the recommended six to eight hours, but this finding was not considered to be statistically significant by the team.In 2014, 35.2% of American adults reported not getting enough sleep with less than seven hours per night, according to the CDC. 2049

The U.S. has now recorded at least 100,000 cases of COVID-19 each day for the last three weeks.On Monday, at least 169,190 new cases of the coronavirus were recorded throughout the U.S., marking 21 consecutive days that the country has seen at least 100,000 new COVID-19 cases.During that time span — dating back to Nov. 2 — the number of people in the country hospitalized with complications from the virus has nearly doubled from 48,557 to 85,836. Currently, about 69% of those hospitalizations are occurring in the South and Midwest, meaning some hospitals in those areas — particularly rural hospitals — are currently operating at capacity.The massive spike in cases has also caused the number of deaths linked to COVID-19 on a rolling 7-day average to nearly doubled from 826 a day to 1,515 a day. The last time the U.S. saw as many deaths per day as it sees now came back in mid-May when the country was still recovering from the virus' silent and uncontained spread in early spring. Over the weekend, the U.S. surpassed 3 million new cases in November alone. The country has recorded 12.4 million cases of COVID-19 since the pandemic began, meaning about one-quarter of all of those cases have occurred this month alone.Despite the bleak outlook on the state of the pandemic in the country, Dr. Anthony Fauci, the county's top expert on infectious diseases, warned Monday that the pandemic could worsen further. He said that if Americans don't follow common-sense public safety measures on Thanksgiving, cases could spike even further in December."The chances are that you will see a surge superimposed on a surge," Fauci said.Fauci recommends limiting Thanksgiving gatherings to members of a single household. He also says Americans need to continue to follow five common public safety measures in order to limit the spread: Adopt uniform mask-wearing, keep social distance, avoid large crowds, gather outdoors as opposed to indoors and continuously wash hands. 1983

The shortest day in what feels like the longest year has arrived. Monday is the Winter Solstice, the day each year when there is the least amount of sunshine in the Northern Hemisphere.The Winter Solstice is the official first day of winter, which lasts until March 20, 2021. It’s when the sun appears at its most southern position in the sky.If it has felt like the world has been getting darker and darker the last six months, that’s because it kind of has been. As the sun spent less and less time shining on the Northern Hemisphere.The closer a person is to the North Pole, the less time they will see the sun. People in Nome, Alaska will only have roughly 3 hours and 54 minutes of sunshine on Monday.There will now begin to be slightly more daylight each day until the Summer Solstice, which is on June 20, 2021.In the Southern Hemisphere, it’s the opposite: it’s the day each year with the most sunshine and marks the beginning of summer in places like Australia, Argentina and South Africa.Many traditional celebrations on the solstice were canceled this year because of the coronavirus pandemic. Including at the world famous Stonehenge, where there is usually a large annual celebration on the solstices. 1222

The Supreme Court Monday rebuffed efforts by states to block funding to Planned Parenthood.It left in place two lower court opinions that said that states violate federal law when they terminate Medicaid contracts with Planned Parenthood affiliates who offer preventive care for low income women.It would have taken four justices to agree to hear the issue, and only three conservative justices -- Clarence Thomas, Samuel Alito and Neil Gorsuch -- voted to hear the case.Chief Justice John Roberts and Justice Brett Kavanaugh appeared to side with the court's liberals in not taking up the case -- showing an effort to avoid high-profile abortion-related issues for now.Roberts and Kavanaugh "likely have serious objections," said Steve Vladeck, CNN Supreme Court analyst and professor at the University of Texas School of Law. "But such votes seem to be a signal that they would rather avoid contentious, high-profile disputes for now, at least where possible."The case concerned whether states can block Medicaid funds from Planned Parenthood affiliates that provide such women with annual health screens, contraceptive coverage and cancer screening.Thomas wrote a dissent for the three conservatives, saying the court isn't doing its job."What explains the Court's refusal to do its job here?" Thomas wrote."I suspect it has something to do with the fact that some respondents in these cases are named Planned Parenthood," he wrote."But these cases are not about abortion rights," he said. "They are about private rights of action under the Medicaid Act. Resolving the question presented here would not even affect Planned Parenthood's ability to challenge the states' decisions; it concerns only the rights of individual Medicaid patients to bring their own suits."The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.
