Researchers are trying to find out as much as they can about great white sharks.After a couple of attacks involving people last year, there are new efforts to learn more about these animals. It’s moments like the incident at Nauset Beach South that shark experts are studying more closely. Video taken of the beach shows white sharks feeding on seals close to the shore. Now, researchers are launching new studies, including one looking at the feeding habits and behaviors of these sharks. “We're essentially going to be giving iPhones to white sharks to track their activity in three dimensions at a really fine scale,” explains Megan Winton, a research scientist with the Atlantic White Shark Conservancy. Winton and other researchers will be tagging sharks with devices similar to what's in smartphones. “We'll be able to identify how often they're feeding on seals. We'll be able to look for relationships with feeding activity and environmental conditions,” Winton says. The data would be given to officials to use to provide better warnings on beaches. The Atlantic White Shark Conservancy is currently pouring over data on a population study they just finished. “Based on the video footage, we were able to identify every shark we saw to an individual level,” Winton says. So far, the researchers have identified more than 300 white sharks. Winton calls it a conservation success story, thanks to protections put in place over the last few decades. “So one thing I like to remind people is that these are large, amazing animals and they're very capable predators and they're certainly deserving of our respect,” Winton says. “But they're not monsters out there, lurking our coastline menacing our beaches. They're big fish out there eating their natural prey item.” White sharks are the only natural predator to seals in the Cape Cod area, which some residents and fisherman see as a nuisance.Researchers want to see how many seals the sharks are eating and if they can impact the seal population. 2023

A fire burning into its fourth day at a petrochemical facility in a suburban Houston area has been extinguished, officials say."As of 3 a.m. today (Wednesday), the firefighting crews on the scene of the ITC Tank Farm Fire are reporting that all tank fires have been extinguished," Intercontinental Terminals Company said in a news release. "Crews continue to spray foam and water on the tanks to facilitate cooling and prevent reigniting of the remaining material."The fire began in a single tank at ITC, a storage facility in Deer Park, Texas, on Sunday afternoon and quickly spread to a second tank, the company said.A specialty firefighting team from Louisiana was brought in to battle the fire, and used foam and water, ITC officials said.By late Tuesday, four tanks remained burning at the ITC facility -- which was a reduction from seven earlier that day, according to Harris County authorities.The battle had by then moved from a defensive mode to an offensive one, according to Ray Russell, a spokesman with Channel Industries Mutual Aid, a nonprofit that handles firefighting, rescue and hazardous material in the local refining and petrochemical industry.No serious injuries have been reported and the cause of the blaze is still under investigation.Schools, businesses closed As the fire burned, sending towering black clouds and a fireball into the sky late Tuesday, neighbors were worried about the heavy, dark smoke even as authorities sought to assure them the air quality remained in the good to moderate range.Before the fire was extinguished, several school districts near the facility, including Deer Park and La Porte, said they would be closed Wednesday and canceled after-school activities, due to the conditions from the fire and changes in the weather."Weather forecasts for Tuesday night and Wednesday call for conditions that could cause the smoke plume from the fire to directly affect our school district and, in an abundance of caution, La Porte ISD has decided to cancel classes for Wednesday, March 20," according to the district's statement.The school districts in the City of Pasadena, Channelview, Sheldon and Galena Park also announced they had canceled classes on Wednesday. San Jacinto College will also be closed.Schools and businesses had briefly reopened Tuesday, even as some worried about the air quality in the area. ITC said that air monitoring near the facility has shown readings "well below hazardous levels."Questions about air qualityRyan Sitton, a commissioner with the Railroad Commission of Texas, which regulates oil and natural gas in the state, said several teams, including those with the chemical facility and the Environmental Protection Agency, are monitoring the air quality."There is a plethora of air quality monitoring that is going on constantly, and it makes me confident that the people of the area are not at elevated risk right now," he said Tuesday.Despite such assurances, some health officials have expressed ongoing concern about the health impacts of the fire."I worry when officials say no health effects are expected," Winifred Hamilton, environmental health science director at the Baylor College of Medicine, told CNN affiliate KPRC-TV. "They're really talking about acute, immediate health effects, and we may still see some of those."The tanks that were on fire contained chemicals that go into making gasoline, including xylene, naptha and pyrolysis gasoline, known as Pygas.Sitton said that chemicals like xylene and toluene can burn in a "disgusting blob," but said there weren't toxins, but could contain particulates.Xylene is a solvent that occurs naturally in petroleum, ITC said. Swallowing or breathing the substance can cause death, while nonlethal exposure can cause eye, nose, throat and skin irritation, among other maladies, 3830

A body that was found in an Oregon home two months ago has been identified as that of long-missing Dennis Day, one of the original members of "The Mickey Mouse Club" TV show from the 1950s, police said.The remains of Day, 76, were found April 4 at his house in the southern Oregon city of Phoenix, but investigators weren't confident enough to identify the corpse until Thursday, Oregon State Police said.Because of the corpse's condition, investigators couldn't use dental records or DNA to identify it, and instead decided Thursday that the remains were Day's through "investigation, evidence and other information," police said in a statement.His death is under investigation, state police said.Day was reported missing in mid-July by his husband, who suffers memory loss and was in a hospital at the time, 822
