By Will Dunham WASHINGTON (Reuters) - Deep beneath Yellowstone National Park, one of the world's most dynamic volcanic systems, lies an enormous, previously unknown reservoir of hot, partly molten rock big enough to fill up the Grand Canyon 11 times, scientists say. Researchers on Thursday said they used a technique called seismic tomography to a produce for the first time a complete picture of the volcanic "plumbing system" at Yellowstone, from the Earth's mantle up to the surface. Yellowstone, which straddles the borders of Wyoming, Idaho and Montana, and boasts a remarkable array of geothermal features including geysers, mudpots, steam vents and hot springs, sits atop a supervolcano that has had three calamitous past eruptions. Scientists already knew of a large magma chamber under Yellowstone that fed the eruptions 2 million, 1.2 million and 640,000 years ago. The new study, published in the journal Science, revealed a second, deeper reservoir 4.5 times larger. "The existence of the second magma chamber does not make it any more or less likely that a large volcanic eruption at Yellowstone will occur. These findings do not change the current volcanic hazard at Yellowstone," University of Utah seismologist Jamie Farrell said. "However, these new findings do provide us, and other researchers, the information needed to gain a better understanding of how magma moves from the mantle to the surface," Farrell added. University of Utah geology and geophysics professor Fan-Chi Lin said the blob-shaped lower magma reservoir in Earth's lower crust is located 12 to 28 miles (20-45 km) under Yellowstone, with a volume of 11,500 cubic miles (46,000 cubic km), or 11.2 times the volume of Arizona's Grand Canyon. This magma chamber is filled with hot, mostly solid and sponge-like rock with portions of molten rock within it. The researchers said about 2 percent of it is completely molten. The upper and lower magma chambers sit above a "plume," or upwelling, originating in Earth's mantle about 40 miles underground and transferring hot materials toward the surface. Scientists had previously suspected a lower magma chamber existed, but until now had been unable to confirm it. The researchers said the technique they used, seismic tomography, is analogous to a CT scan of the body, using seismic waves as they travel through the Earth to image the subsurface, distinguishing between rock of various densities. They also combined both local and distant earthquake measurements to image Yellowstone's complete magma system. (Reporting by Will Dunham, editing by G Crosse)

WASHINGTON (Reuters) -A U.S. Coast Guard ship fired about 30 warning shots after 13 vessels from Iran’s Islamic Revolutionary Guard Corps Navy (IRGCN) came close to it and other American Navy vessels in the Strait of Hormuz, the Pentagon said on Monday. This is the second time within the last month that U.S. military vessels have had to fire warning shots because of what they said was unsafe behavior by Iranian vessels in the region, after a relative lull in such interactions over the past year. Pentagon spokesman John Kirby said the warning shots were fired after the Iranian fast boats came as close as 150 yards (450 feet) of six U.S. military vessels, including the USS Monterey, that were escorting the guided-missile submarine Georgia.

GoFundMe / St. John’s County SheriffAfter a daylong search, a 13-year-old cheerleader was found murdered in Florida—and police have arrested a 14-year-old boy who attended the same school.Tristyn Bailey’s family reported her missing at 10 a.m. on Sunday, and residents of St. Johns County came out in droves to look for her. The hunt ended tragically that evening when her body was spotted in a wooded area.The St. Johns County Sheriff’s Office did not provide a cause of death; they said the seventh grader was clothed but did not confirm reports that she had on her cheerleading uniform.Sheriff Rob Hardwick said the teen arrested and charged with second-degree murder is the only suspect connected to Tristyn’s death. The Daily Beast is not naming him because he is a juvenile and authorities have not decided whether to charge him as an adult.“Our investigative team is out there interviewing all kinds of witnesses, whether directly or indirectly involved in this case,” Hardwick said at a press conference.“We have a suspect in custody. That is the only suspect that has to do with the death of Tristyn.”Hardwick said investigators are looking through a trove of social media posts that could be helpful to the case, but he did not comment on reports that a Snapchat under the boy’s name posted a photo of him in a patrol car with the caption: “Hey guys has anybody seen Tristyn lately?”Both Tristyn and the suspect attended Patriot Oaks Academy in St. Johns, though police said it was unclear how they knew each other or if they were in the same class.The sheriff acknowledged that news of Tristyn’s death had sparked an outpouring of emotion in the tight-knit county.“We know the community is angry,” Hardwick said.“We have a person charged with a serious crime, and we have a family that’s grieving the loss of a loved one. A child—a 13-year-old child.”Locals came out Monday night for a series of vigils—at the community center where she was last seen alive and at Infinity Allstars, the gym where she was a competitive cheer athlete. Ribbons in aqua, her favorite color, festooned mailboxes across the area in her memory.“It’s just heartbreaking for her family who can never see her again, be able to talk to her and say loving words to her,” Reagan Anderson, a friend of Tristyn, told Jax4News.Read more at The Daily Beast.Got a tip?

Shoppers and staff at a New Zealand supermarket were being praised for their bravery Monday after authorities said they managed to stop a frenzied man from hurting others after he stabbed four people in a random attack, severely wounding three of them. New Zealand Police Superintendent Paul Basham said he'd watched CCTV footage of the attack at a Countdown supermarket in the city of Dunedin and the actions of the bystanders in detaining the man until police arrived was “nothing short of heroic.” Two of those wounded were supermarket staff members.
Community members told local media that Tristyn Bailey will be remembered as a cheerleader, a daughter, a sister, and a friend.
The Indian government has told doctors to look out for signs of mucormycosis or "black fungus" in COVID-19 patients as hospitals report a rise in cases of the rare but potentially fatal infection. The state-run Indian Council of Medical Research (ICMR) said at the weekend that doctors treating COVID-19 patients, diabetics and those with compromised immune systems should watch for early symptoms including sinus pain or nasal blockage on one side of the face, one-sided headache, swelling or numbness, toothache and loosening of teeth. The disease, which can lead to blackening or discolouration over the nose, blurred or double vision, chest pain, breathing difficulties and coughing blood, is strongly linked to diabetes.
