The widespread use of toothpaste and mouthwashes with added fluoride in recent decades appears to have diminished the known public health benefits of water fluoridation, a new study suggests. Hundreds of U.S. communities, from Amery, Wisconsin, to Union County, North Carolina, are opting out of water fluoridation. Still, she noted, “contemporary studies are showing that water fluoridation is beneficial.”Before fluoride toothpastes were widely available to consumers, adding the mineral to water provided a clear benefit to teeth. Fast-forward to 2024: About 75% of the U.S. population has tap water with added fluoride at recommended levels of 0.7 milligrams per liter of water. “Water fluoridation is still effective at reducing cavities,” he said.

Exscientia's growth was bolstered by government support: The company didn't take venture funding until 2019. Exscientia wouldn't be where it was, Taylor said, without the support of the UK higher education system and government funding. Martin Tangney, the chief scientific officer of Edinburgh-based Celtic Renewables, said the £11 million of funding his company received in 2015 from the UK government was "pivotal."

CNN —Ancient DNA recovered from the remains of a sixth century Chinese emperor who ruled during the country’s dark ages has shed some light on what the leader may have looked like. Emperor Wu ruled China as part of the Northern Zhou dynasty from 560 to 580 and is credited with unifying the northern part of ancient China during a particularly chaotic period. “Our analysis shows Emperor Wu had typical East or Northeast Asian facial characteristics.”The authors said they hoped ancient DNA might shed light on Wu’s cause of death. The genetic analysis showed that Emperor Wu intermarried with ethnically Han Chinese, China’s dominant ethnic group today. “It’s interesting to see the genetic study, but none of the findings of this genetic study are surprising at all,” Miller said.

The Chandrayaan-3 spacecraft landed on the lunar surface near the moon's south pole on Wednesday. The historic occasion marked the country as a global space power and only the fourth nation to achieve a lunar landing. Chandrayaan-3 has already returned several images and rolled out its Pragyan rover on the lunar surface. Meanwhile, Russia’s Luna 25 lander crashed into the moon, causing experts to question the country’s future lunar ambitions.

☆ Fact Check-In wake of Maui fires, here’s why some trees survive damage

Some posts on social media in the wake of the fires on the Hawaiian island of Maui, however, suggested that the fact some trees had remained standing showed proof that the fires were somehow engineered or steered to intentionally burn homes and vehicles, leaving trees unscathed. Reuters photographs and satellite imagery of the Lahaina Banyan Court area produced by Maxar Technologies shows buildings, vehicles and trees damaged following the fires (shorturl.at/bpsTX), (here). Other trees were more heavily damaged, but remained standing, Reuters pictures show (here), (here). Regardless, the fact that some trees could remain standing or were less damaged than cars or buildings during a fire is not abnormal. Trees sometimes survive severe damage during fires due to factors including their water content and the ways a fire spreads.

☆ Bonnie Prince Charlie’s face recreated using death masks

CNN —Researchers at the University of Dundee have recreated the face of Bonnie Prince Charlie as he appeared when leading the unsuccessful 18th century Jacobite rebellion as he sought to reclaim the British throne for his father. In the image, Bonnie Prince Charlie appears with blonde curly hair, wide eyes and acne on his skin, revealing a different side to the more conventionally heroic figure he has traditionally been depicted as. I did want to show a different angle with that.”The image was created using death masks of the prince, which were photographed and mapped. Using state-of-the-art software, 3D models were then produced, allowing researchers to “de-age” the prince, the university added. A portrait of Bonnie Prince Charlie painted in 1738 by Louis Gabriel Blanchet, is on display at the National Portrait Gallery in London,.
