Mystery is no stranger to the Great Pyramid of Giza. For centuries, scientists and archaeologists have probed inside the largest and oldest of Egypt's famed pyramids.But until now none had stumbled upon a 30-meter-long space hidden within its limestone and granite walls.An international group of scientists has used modern technology to visualize the inside of the pyramid, according to an article published Thursday in the journal Nature. 448

Monday morning, the CDC removed what it calls was a “draft version of proposed changes” to their website that seemed to indicate they were embracing mounting evidence that COVID-19 is airborne and is transmitted through tiny droplets that can linger in the air and spread farther than six feet.“A draft version of proposed changes to these recommendations was posted in error to the agency’s official website. CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the update language will be posted,” the CDC website now reads.The website was changed over the weekend, according to multiple media reports, to reflect several updates to their guidance about how COVID-19 spreads and preventative measures to take.The “draft” changes included stating COVID-19 transmits through the air and warned about poorly ventilated situations, saying that is “thought to be the main way the virus spreads.”On the Centers for Disease Control and Prevention’s website about coronavirus, under how it spreads, they listed the main way as: “Through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection.”They also had updated the guidance that particles can remain in the air longer and travel farther than originally thought.“There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes). In general, indoor environments without good ventilation increase this risk,” the CDC website read over the weekend.The website has been changed back to their previous guidance which states COVID-19 is believed to be transferred through larger droplets through close contact, closer than six feet, with a person who coughs, sings, or otherwise expels these larger droplets carrying the virus.The updated draft passages and comments on smaller particles and ventilation appeared to embrace recent studies from the CDC.Including one released by the CDC earlier this month showing Americans with positive COVID-19 test results were twice as likely to eat at a restaurant or cafe than those who tested negative.“Reports of exposures in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance. Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use,” that report stated.In the “draft” changes to the CDC website, they included a preventative measure about ventilation, stating “Airborne viruses, including COVID-19, are among the most contagious and easily spread.” That passage is no longer on the website.The draft changes on the air transmission of COVID-19 also came on the heels of the CDC’s director, Dr. Robert Redfield, saying masks could be even more helpful in combating the coronavirus than a vaccine. President Donald Trump said later Redfield was confused by the question and misspoke.The World Health Organization changed their guidance and noted the prevalence of air transmission, and those particles lingering in the air, earlier this summer in July. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 3665

NATIONAL CITY, Calif. (KGTV) - The National City City Council voted 4-1 Tuesday night to introduce a new ordinance that aims to close a loophole in a state law that prohibits the retail sale of cats, dogs and rabbits.Enacted on January 1, 2019, the new state law prohibits stores from selling animals unless they come from shelters or non-profit rescues. However, some pet stores have continued to sell what appear to be purebred and designer mix puppies that come from a small group of newly formed rescue organizations.One of those groups is called Bark Adoptions, based in Menifee. A 10News investigation found Bark Adoptions had been importing puppies from another supposed rescue in Iowa that had ties to commercial breeders.At National City Puppies, one of the two remaining pet stores in the city, signs on the dog cages in May showed they came from Bark Adoptions.The manager of National City Puppies, David Salinas, said he did not know where the dogs at his store came from beyond the listed rescues. But he defended his store in front of the city council, saying it comes down to consumer choice.“It’s the American way to have the freedom to choose where to buy a puppy,” said Salinas.As written now, the new ordinance says “a pet shop or retail pet store or its operator shall not sell, deliver, offer for sale, barter, auction or otherwise dispose of a cat, dog or rabbit.”There are exceptions, however, that would allow pet stores to offer “a cat, dog or rabbit owned by an animal shelter or animal rescue organization for purposes of adoption” but only if “the pet shop does not receive any fee from the adoption and does not have any monetary or ownership interest” in the animals. The ordinance still has to come back to the city council for a second reading and adoption before it goes into effect. 1835
