Activated charcoal is the craze in the beauty industry to help get those pearly whites, but at what cost is it taking on oral health?What is activated charcoal?It's not the charcoal used in your backyard barbeque. According to Dr. Todd Shatkin of Aesthetic Associates Centre in Amherst, New York, it's a slightly abrasive powder usually formed by coconut and is used in many different aspects of the health industry. Activated charcoal is an absorptive property, and it's designed to absorb and lift blemishes from teeth.It's used for cleansing, weight loss treatments, and skin care products. Now it's being used for teeth whitening to remove stains. How does it work?A toothbrush is dipped into the powder and is brushed directly onto teeth. The activated charcoal powder removes the extrinsic stains; stains that are caused by wine, coffee and other foods and drink. "Charcoal-based products would be good to remove the surface stain, but it won't internally bleach or whiten the teeth from within," Shatkin said. Is activated charcoal safe to use?Shatkin says yes.He says, to first make sure the product is FDA approved, and check the abrasiveness level. "The enamel is really pretty strong," he said. "If you're in the enamel your probably not going to do any harm to your teeth. But if the patient has worn through the enamel into the dentin, it causes sensitivity and causes discomfort. If you use abrasive materials on the dentin, it will just make things worse."He says, in the end, it all comes down to good oral hygiene and visiting your dentist every three to six months. 1716

After a slew of women came forward to accuse producer Harvey Weinstein and other notable figures in media of sexual harassment, CNN's Anthony Bourdain expressed regret for his participation in and validation of a culture he sees as similarly sexist: the restaurant industry.In an interview Thursday with Poppy Harlow on CNN's "New Day," Bourdain -- whose girlfriend, Asia Argento, is among Weinstein's accusers -- explained that he had "spent nearly 30 years in the restaurant industry, an industry and a culture that has been pervasively hostile to women." 565

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

ALPINE, Calif. (CNS) - A 61-year-old Alpine man is the first person in San Diego County to test positive for West Nile virus this year, local health officials reported Wednesday.The man, whose name was withheld, was hospitalized and has recovered. The California Department of Public Health confirmed his WNV diagnosis on Tuesday.The man said he had traveled to Yuma, Arizona where it is believed he contracted the virus, according to the San Diego County Health and Human Services Agency.Since Jan. 1, there have been two West Nile virus positive detections in mosquitoes during routine trapping by the county vector control program, one in the Del Mar Area and the other in the Black Mountain Ranch area.There were only three human cases of West Nile virus in San Diego County in 2019 and two in 2018.The state has reported 11 people infected statewide so far in 2020, including a child in neighboring Orange County who was diagnosed sometime last week and was hospitalized but is expected to recover.West Nile virus is mainly a bird disease but can be transmitted to people by certain species of mosquitoes that first feed on an infected bird or animal and then a bite a person.Around 80% of people who become infected with West Nile virus never know it and never suffer any symptoms. About one in five people who are infected develop a fever and other symptoms such as headache, nausea, fatigue, skin rash or swollen glands. About 1 out of 150 infected people could become extremely ill and die.People older than 50 and who have underlying medical conditions are at heightened risk.Public health and environmental health officials recommend following the county's "prevent, protect, report" guidelines, which are designed to help residents protect themselves from mosquitoes that transit West Nile virus as well as invasive Aedes mosquitoes that can transmit tropical diseases, including Zika, dengue and chikungunya.Dump out or remove any item inside or outside homes that can hold water, such as plant saucers, rain gutters, buckets, garbage cans, toys, old tires and wheelbarrows. Mosquito fish, available for free by contacting the county's vector control program, may be used to control mosquito breeding in backyard water sources such as unused swimming pools, ponds, fountains and horse troughs.Wear long sleeves and pants or use repellent when outdoors. Use insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or IR3535. Make sure screens on windows and doors are in good condition and secured to keep insects out.Finally, report increased mosquito activity or neglected, green swimming pools and other mosquito-breeding sources -- as well as dead birds -- to the vector control program by calling 858-694-2888 or emailing vector@sdcounty.ca.gov.Mosquito season in Southern California generally spans May to October. 2856
