The flower fields have been around for 50 years. The Flower Fields are owned and operated by the Ecke Family, the onsite grower and floral sales is handled by Mellano and Company. They share their passion for beauty and expertise inthe flower business, with a combined experience of 100 years.The Flowers Fields are known all over the world. There is no other place like it with over 50 acres of ranunculus flowers in 13 different colors. The flowers are delicate, its seed is tiny, paper thin, and smaller than an oat flake. The seed has to be mixed with water and sand, then it is placed in a cooler for two weeks to trick the seed into thinking it had a winter. Ranunculus do best in temperate climate. Morning fog, cool mornings, and temperatures in the 50s and 60s help the flower production. The flower fields are ecofriendly, they use a drip irrigation system. It places water exactly where the seed is, using the water needed and not more than that.Extreme temperatures can be costly and one of the biggest threats to the crop. Winter warm ups are less than ideal but too much rain is also bad. The team at the Flower Fields has learned to tackle the weather, but every year presents new challenges. This year they are expecting the best season yet, you can visit the Flower Fields through Mother’s Day weekend. Next year expect a new color to be added to the already beautiful fields. 1402

The current pandemic has led many people to spend more time outside this summer, with many setting up backyard pools or heading to lakes and beaches. But all of that water recreation has led to a spike in drownings."We were seeing it across a national level and when we looked at our local data, we saw that we were following as part of that trend," said Dawne Gardner, an Injury Prevention Specialist with Cincinnati Children's Hospital. Normally, they see anywhere from one to three child drowning deaths a year. This summer, they've seen nine."We know that with parents, they're looking for alternative vacations and things are limited right now with COVID-19 and still being able to social distance. We know that with those limited options, parents are utilizing backyard pools more," said Gardner. Gardner says it may seem safe to have your child swimming in your backyard but she says safety goes way beyond location. Supervision is key."You can't be distracted. So, when kids are in and around water, parents have to be on top of the supervision. Every second counts. And if you take your eyes off of them in the water even for a second, that could be that quiet second that a child slips under water," said Gardner.Other areas of the country also saw a dramatic change in the number of child drownings, but not all were bad. Johns Hopkins All Children's Hospital in St. Petersburg, Florida reported that from March through June, doctors saw a 150 percent increase in child drownings and near-drownings compared to the same time period last year. While at Valley Children's Hospital in Fresno County, California, officials reported a sharp decline in child drownings. The shelter-in-place restrictions from the COVID-19 pandemic don't just prompt families to take part in more water-related activities, they did so at a time when most swimming lesson facilities had to shut down.It was a concern for Aqua-Tots that kids were missing out on a crucial time for swim lessons. "It was incredibly hard to close the doors to our businesses at such a crucial time of year where families and children are outside in the heat and they're flocking to bodies of water. They're swimming a lot more often so it was very tough," said franchise owner Lindsay Thayer of Aqua-Tots. Aqua-Tots has 100 locations in 14 different countries, including here in the U.S. They teach swimming lessons to children, teens and adults. Thayer says to help prevent accidental drownings, children need to learn water safety."Children need to know that they need to ask permission, when to approach a body of water, when to get into a pool or lake with mom or dad, a guardian or adult before doing so. Also, swim lessons are especially important. Participating in a formal swimming lesson program can reduce the risk of drowning by 88% in children between the ages of one and four," said Thayer.Jen Deis, the General Manager of Goldfish Swim School near Cincinnati agrees. Goldfish Swim School provided some online tutorial videos for parents to help them teach their children some basic swimming skills. But she says swim lessons, even during the winter, are vital."Swimming is like any other sport or skill. Kids need constant reinforcement of those swim skills to remember those water safety skills year round. While, right now it is a top priority, with kids around bodies of water a lot of times, keeping them consistent in their swim lessons is really important," said Deis.Cincinnati Children's Hospital reports the nine drowning victims ranged in ages from young children to teenagers. Ensuring fences or other barriers are around pools is also important.They're urging parents to be vigilent when it comes to keeping your children safe around water, hoping to prevent any more accidental drowning deaths this summer. 3807

The FBI's top liaison on Capitol Hill is out.Greg Brower, an FBI assistant director and head of the Office of Congressional Affairs, stepped down last Friday after a year on the job. In the role, Brower was on the receiving end of a pack of congressional probes into the law enforcement agency's conduct.The decision, a "tough" one he made of his own accord, Brower said, follows other high-level departures from the bureau as FBI Director Christopher Wray assembles his own team of close advisers."It was tough but I had an offer I couldn't refuse from a great law firm," Brower said in an interview Thursday. "It was very gratifying to be a part of that team. I could not be more proud of how people work and how committed they are to the mission."Brower was appointed to the position by then-FBI director James Comey in March of 2017 after serving as the bureau's deputy general counsel. He will join the lobbying and law firm Brownstein Hyatt Farber Schreck as a shareholder in the litigation department.The work in the legislative affairs office has heated up during Brower's tenure, as the fallout from Comey's firing by President Donald Trump has fanned a growing mistrust of the FBI among some lawmakers and spurred a round of congressional investigations.Not long before Brower's departure, the chairman of the House Judiciary Committee slapped the Justice Department with a subpoena for documents related to a trio of recent controversial decisions made by the FBI, including the move in 2016 to not charge Hillary Clinton after the probe of her email server and the internal recommendation by an FBI office to fire former FBI Deputy Director Andrew McCabe.In response, Wray said last week that the pace of document production for congressional inquiries at the bureau was "too slow" and doubled the number of FBI staff responsible for reviewing the records.On Thursday, Brower said he had worked with the FBI's Office of the General Counsel, which reviews the internal documents for release, before his departure to get a "a better plan in place" to respond to "an unprecedented wave of oversight requests.""That's all really on track," Brower said, adding that his decision to leave had nothing to do with the probes. "As the director mentioned, it's probably taking longer than it should, but the volume is just so unprecedented that we finally had to put more people on it."Brower's year atop the office saw big wins for the bureau on Capitol Hill, including a six-year extension of the controversial foreign surveillance program known as FISA Section 702 in January and the recent passage of the CLOUD Act, which makes it easier for the US to collect data stored overseas."I felt like the biggest things I set off to do in '17 were done and I felt less bad about leaving," he said.Brower is the fifth top adviser to the director to leave his position since Trump tapped Wray to replace Comey in June. 2943

  

The FDA wants to remind parents that infants under 1 year old can't have honey after four infants in Texas were hospitalized with botulism. Each of the infants had been given a pacifier containing honey, according to the Texas Department of State Health Services. Symptoms of infant botulism include difficulty breathing, constipation, poor feeding, general weakness, drooping eyelids and loss of head control. It can lead to death if left untreated. Botulism is a serious illness caused by a toxin that attacks the body’s nerves and can cause difficulty breathing, paralysis and even death. Honey may contain bacteria that produces the toxin in the intestine of babies that eat it.By the time children get to be 12 months old, they’ve developed enough other types of bacteria in their digestive tract to prevent the botulism bacteria from growing and producing the toxin. 910

  

The FDA's Vaccines and Related Biological Products Advisory Committee panel has endorsed a second COVID-19 vaccine in the United States.Now the FDA is expected to act quickly to authorize the Moderna vaccine for emergency use and keep it on schedule to be distributed to patients across the country as early next week.The panel voted 20 yeses and one abstain.WATCH RECAP:With the panel recommending EUA, the FDA as a whole would then need to file its own EUA approval. The final step would be a formal recommendation from the Centers for Disease Control and Prevention that Americans should receive the vaccine.Last Thursday, the committee voted in favor of granting EUA to Pfizer's COVID-19 vaccine. By Monday, it was being administered across the country.The panel's meeting comes days after a key FDA report upheld the safety and efficacy results of the Moderna vaccine's Phase III trials. Those statistics showed that the vaccine was 95% effective with no severe side-effects."FDA has determined that the Sponsor has provided adequate information to ensure the vaccine's quality and consistency for authorization of the product under an EUA," the report said.An approval of Moderna's vaccine would immediately boost the supply levels of COVID-19 vaccines in the U.S. Millions of doses are ready to be shipped across the country as soon as approval is granted.The arrival of COVID-19 vaccines comes amid the bleakest stretch to date in the COVID-19 pandemic. The U.S. is currently seeing the highest level of new cases (213.000) and deaths (2,500) each day, according to seven-day rolling averages totaled by the COVID Tracking Project. More Americans than ever are also battling the virus in a hospital (113,000). 1725
