Amateur fossil enthusiast Phil Mullaly knew he had found something special when he spotted something glimmering in a boulder.Mullaly was walking along Jan Juc, a renowned fossil site along Victoria's Surf Coast in South Australia when he spotted a partially exposed shark tooth in the rock."I was immediately excited, it was just perfect," Mullaly said.That was just one of multiple teeth Mullaly found that day in 2015. Three years later, scientists have confirmed his hunch, saying Thursday that the teeth are all about 25 million years old and belonged to an extinct species of mega-toothed shark -- the Great Jagged Narrow-Toothed Shark (Carcharocles angustidens).The ancient shark was believed to grow up to about 9 meters (30 feet) long, double the size of a great white shark. The teeth discovered on the beach were around 7 cm (2.75 inches) in length.Mullaly's is one of the rarest finds in the history of paleontology, according to Erich Fitzgerald, a palaeontologist at Museums Victoria who led a team to excavate the site where the initial fossils were found."If you think about how long we've been looking for fossils around the world as a civilization -- which is maybe 200 years -- in (that time) we have found just three (sets of) fossils of this kind on the entire planet, and this most recent find from Australia is one of those three," Fitzgerald told CNN. 1382

After issuing previous guidance that encouraged schools to close in areas with high transmission of the coronavirus, the CDC is now emphasizing that schools reopen this fall.The guidance issued on Thursday is in line with a Trump administration priority to reopen schools this fall.“It is critically important for our public health to open schools this fall,” said CDC Director Dr. Robert R. Redfield. “The CDC resources released today will help parents, teachers and administrators make practical, safety-focused decisions as this school year begins. I know this has been a difficult time for our Nation’s families. School closures have disrupted normal ways of life for children and parents, and they have had negative health consequences on our youth. CDC is prepared to work with K-12 schools to safely reopen while protecting the most vulnerable.”Now in areas with, as the CDC calls it, "substantial, uncontrolled transmission" of the coronavirus, "Schools should work closely with local health officials to make decisions on whether to maintain school operations. The health, safety, and wellbeing of students, teachers, staff and their families is the most important consideration in determining whether school closure is a necessary step. Communities can support schools staying open by implementing strategies that decrease a community’s level of transmission. However, if community transmission levels cannot be decreased, school closure is an important consideration."In areas with substantial, controlled transmission, "Significant mitigation strategies are necessary." In addition, social distancing and face covering policies should be implemented, the CDC said.Previous guidance called for schools in areas with substantial community transmission (the CDC did not distinguish between uncontrolled or controlled) to, "Implement extended school dismissals (e.g., dismissals for longer than two weeks). This longer-term, and likely broader-reaching, dismissal strategy is intended to slow transmission rates of COVID-19 in the community. During extended school dismissals, also cancel extracurricular group activities, school-based afterschool programs, and large events."In previous guidance, the CDC called on schools to keep students 6 feet apart. But many classrooms do not have the space to properly socially distance students. The Trump administration’s response appears to be a 5 billion request to Congress. President Donald Trump said that the funds, in part, could be used for schools to open additional spaces and hire additional staff in order to help space students.The CDC said that the “best available evidence from countries that have opened schools indicates that COVID-19 poses low risks to school-aged children, at least in areas with low community transmission, and suggests that children are unlikely to be major drivers of the spread of the virus.”But that guidance contradicts a South Korean study published by the CDC earlier this week.The study said that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, that school closures and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children.“The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.In its new guidance, the CDC said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”But the CDC also weighed the concerns of the coronavirus against providing physical activity, food and safety for students. The CDC said studies project that the childhood obesity rate would increase by 2.4% if schools remained closed through December.This guidance comes as cases in the US steadily increased earlier this month, prompting coronavirus death counts to rise in recent days. The US had back to back days of more than 1,000 people reportedly dying from coronavirus-related illnesses, according to Johns Hopkins University.To read the CDC’s latest guidance, click here. 5184

A 6th-grade student at Dr. David L. Anderson Middle School in Martin County, Florida has been charged with a misdemeanor after he simulated a shooting, pretending to have a semi-automatic weapon.The Martin County Sheriff's Office said students told teachers that the 6th-grade student allegedly said he had a gun for protection. A school resource officer searched the student and his backpack and did not find a weapon. The child was allowed back to class, but a deputy said, in class, the student put his hands up as if he was firing a semi-automatic weapon and began to make pop noises. The Martin County Sheriff's Office was called out to the school and the student was arrested for disrupting a school function. He is charged with a misdemeanor. No weapon was found. Parents were notified that there was an incident."It was very unnerving and disturbing and once again it's the kids that are suffering and it freaked me out after dropping off my son today, giving him a kiss and knowing how the other parents feel about yesterday and that the kids aren't here. It's heartbreaking," said Shari Sullivan, whose son is in 7th grade. MESSAGE FROM ASSISTANT PRINCIPAL TO PARENTS:Good afternoon, this is Joe Flanagan, Asst Principal of Anderson Middle School.  I have an important message to share with you.  Today, school officials worked in partnership with the Martin County Sheriff’s Office as we became aware that one of our students made a non-credible threat to his classmates and teacher related to the recent tragedy.  The student is in custody of the Martin County Sheriff’s Office and is being charged with a misdemeanor for disruption of a school function. 1709

Across the U.S., employees at a large media company are working to put books in the hands of children living in poverty.That company — E.W. Scripps — is inviting the public to help.The Scripps Howard Foundation’s annual “If you give a child a book …” literacy campaign has started and will run through the end of August. The literacy campaign has distributed more than 100,000 new books to children across the country since 2017.Now in its third year, the campaign is a partnership of the Foundation, employees of The E.W. Scripps Company and donors who provide matching gifts to advance childhood literacy by increasing access to books. ?Every dollar raised during the “If you give a child a book … ” campaign is used for the purchase of books for children who need them most. Books are purchased at cost through a partnership with Scholastic Book Fairs, further maximizing the purchasing power of every donated dollar.Following the campaign, Scripps news organizations choose a local nonprofit group that works with children and families to receive the books. In addition, the TV stations air stories about the importance of literacy and how to get involved, further amplifying the impact of the campaign.“There is an intrinsic link between the ability to read and a child’s ability to succeed in life,” said Liz Carter, president and chief executive officer of the Scripps Howard Foundation. “By helping children learn to read, we can assure they can have the tools and information they need to reach their potential.”Books presented to program partners on National Reading Day on January 23, 2019.Visit http://ifyougiveabook.com for more information on how to give to this the campaign. 1703
