A giant jellyfish the size of a human has stunned a diver off the south-western coast of England.The incredible creature -- a barrel jellyfish -- was spotted near Falmouth by broadcaster and biologist Lizzie Daly, who described the encounter as "breathtaking.""What an unforgettable experience," she added. "I know barrel jellyfish get really big in size but I have never seen anything like it before!""It was the best thing I've ever done," she said in a video of the meeting.Daly, who was exploring the waters as part of her campaign "Wild Ocean Week," added the jellyfish was a big as she is.Barrel jellyfish are the largest species of jellyfish in British seas, but it is extremely rare to spot one of the size Daly did.They typically grow up to one meter (3.2 feet) and weight up to 25 kilograms (55 lbs), according to The Wildlife Trusts. Barrel jellyfish are frequently washed up on the UK's coastlines during the summer months. 947

SAN DIEGO, Calif. – If COVID-19 cases spike this fall, hospitals want to make sure they have enough ventilators. But that's only one part of the equation. They'll also need more trained staff to help operate the complex machines. "When governors have been asking for tens of thousands of ventilators, that's great, but there's only a finite group of people that are skilled and trained and authorized to use those ventilators," said Jim Archetto, Vice President of Gaumard Scientific. The machines help patients breathe, pumping oxygen into their bodies. "But what's critically important is how you control that pressure. If you pump too much pressure into a patient, your lungs will explode," explains Archetto. The stakes couldn't be higher, so hospitals are now working on training more staff members to help operate the devices. That's where Gaumard comes into play; their lifelike robots simulate not only medical emergencies but also emotions. "We'd really rather have these nurses and docs practice on a simulator before they're working on a live patient in a critical care situation," said Archetto. Pediatric Hal is a 5-year-old patient simulator who can breathe, bleed, move, cry, and talk. "He can actually be plugged into a real ventilator, and that ventilator can take control of his breathing functions," said Archetto. Companies like Gaumard have seen a spike in demand for this specialized training. Archetto says they've received calls from medical schools, hospitals, and even manufacturing companies needing to test their new ventilators. With in-person training on hold, Gaumard is using Zoom to train professionals virtually on how to use their simulators. "I can provide whatever symptoms I'd like for him to mimic, for COVID, or anything for that matter," said Archetto. Lincoln Healthcare, located just outside of Philadelphia, had already developed a program using Hal to train their at-home nurses on how to operate ventilators. "We really wanted to make sure our nurses were armored with the best training, the best emergency preparedness that could arise in the home," said Autumn Lincoln, vice president and co-founder of Lincoln Healthcare. When the pandemic hit, they opened up the 2232

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
