The US Supreme Court has ruled in favor of Black Lives Matter protest organizer Deray Mckesson.A Louisiana police officer had sued to hold Mckesson accountable for injuries the officer sustained in 2016 when he was hit by a heavy object.Mckesson didn't throw the object.The person who did is still unidentified.A lower court ruling had allowed the suit to move forward.Critics said the decision would dismantle the Civil Rights era precedent safeguarding the first amendment right to protest.The Supreme Court's decision wiped away the earlier ruling, sending the case back to the lower courts to further review Louisiana law.The justices ruled the case needed more guidance from state courts before important constitutional questions are considered. 758

The world’s population has been growing, spiking in the last few centuries, and now sits around 7.6 billion. A study published this week suggests global population will peak around the year 2064 at roughly 9.73 billion people.Researchers looking at the models believe the world’s population will then begin declining, reaching roughly 8.79 billion in the year 2100. Their reasoning for the decline is that “continued trends in female educational attainment and access to contraception will hasten declines in fertility and slow population growth.”According to the study, funded in part by the Bill and Melinda Gates Foundation and published in The Lancet, the five largest countries, population-wise, in 2100 are projected to be India, Nigeria, China, the U.S. and Pakistan. They are projecting America will have a population of roughly 336 million people in 2100. Currently, there are an estimated 331 million people living in the U.S.The average life expectancy in 2100 will be around 80 years old. The current global life expectancy is estimated at 72 years old. 1073

The U.S. recorded more than 120,000 new cases of COVID-19 on Thursday as cases continue to skyrocket across the country.According to Johns Hopkins University, there were 121,888 new cases of COVID-19 recorded across the country on Thursday. That shatters the previous record of 102,000 cases that were reported on Wednesday.Johns Hopkins reports that more than 1,200 people died of the virus in the U.S. on Thursday, the highest death total since Sept. 15. The highest daily death total throughout the pandemic occurred on April 15, when 2,600 people died.According to Johns Hopkins, COVID-19 is currently spreading faster in the U.S. than it is anywhere else in the world. The U.S. has recorded an average of about 80,000 new cases of COVID-19 in the last seven days; the country with the second-highest rate of new cases is India, with an average of about 45,000 new cases of the virus each day.Health officials warn that the U.S. is entering what could be the most dangerous and deadly period of the pandemic, as colder weather forces social gatherings indoors, where the virus is more easily spread.Since the start of the pandemic, there have been 9,606,369 cases reported in the US, 234,911 being fatal. Both totals mark the most of any country. 1258
