Just about anything with a wireless connection could be a target for hackers to attack, including personal computers, tablets and even baby monitors. But what about medical devices?The Food and Drug Administration (FDA) is monitoring that, too.Cardiologist Cynthia Tracy, with George Washington University Medical Center, implants pacemakers into people’s bodies almost daily.“In a typical situation, there might be two electrodes that pass through these veins and into the heart,” Tracy explains of the device.The device, which is about the size of silver dollar, controls a patient's heart beat and sends data to doctors by using the internet."They have a Bluetooth connection somehow that allows the device to communicate with something external," Dr. Tracy says.That wireless connection is where the concern comes in.“There's no such thing as a medical device without vulnerabilities,” says Suzanne Scwarts, who leads medical device cyber security for the FDA.Shwarts says after a series of security problems discovered in various medical devices, cyber security is front and center.“We want patients to definitely be able to understand what are current risks today,” Shwarts says.Dr. Tracy explains while security shortcomings may be there, an actual hack to something like a pacemaker would be a bit difficult.“I couldn't from here reprogram someone that's out there in the lobby, Dr. Tracy says."They would have to be fairly close in order for me to do anything to their device."Though there have been no direct hacks to patients to date, the threat is there, which is why the FDA is ramping up its efforts to make sure the hacking of medical devices doesn't become reality. 1689

JACKSON, Miss. (AP) — Mississippi's largest religious group says state lawmakers have a moral obligation to remove the Confederate battle emblem from the state flag because many people are "hurt and shamed" by the symbol. The Mississippi Baptist Convention has more than 500,000 members in a state of 3 million people. The convention said Tuesday that many see the flag as "a relic of racism and a symbol of hatred."It joins the other influential groups, including the governing body for college athletics, that are calling for Mississippi to change its flag. Republican Gov. Tate Reeves says flag design should only be determined by a statewide vote. 659

JAMUL, Calif. (KGTV) - A Jamul family is mourning the loss from COVID-19 of a former little league coach and employee at Taylor Guitars.Greg Denny came down with a sinus headache in the second week of June. A trip to the ER revealed double pneumonia. Then came a positive COVID-19 test and fever, before his wife Kim brought him back to the hospital.“Five days of fever, hadn't been able to break it. He was at 102°,” said Kim Denny.A week after Greg was admitted, he was placed on a ventilator.“It was very emotional, like a roller coaster. Good one day and then things changed that same day,” she said.Eventually, the bad days took over. His kidneys failed. So did his pancreas. Then he got a blood infection. Last Friday, Greg — an Army veteran, father of two and grandfather of four — passed away at the age of 48.“He was my soulmate, my best friend and now he's my guardian angel,” she said.Kim calls her husband a wonderful dad and grandfather.“He’s the best man I’ve ever known,” said Dillon Wulff, Greg’s adult son.For the last five years, Greg has worked in security at Taylor Guitars. For more than two decades, he has coached or volunteered for little league games in Spring Valley.In her time of grief, Kim takes comfort in the daily game they played called, "I love you more."“Whoever said it first would win. So constantly, he'd get up and say, ‘I love you more.’ I'd get up and say, ‘I love you more,’" said Kim.They would play that game until the day he went on the ventilator.As for where the origin of the COVID-19, she has no idea. He always wore masks.“My husband was very safe … So, it’s scary. People need to take every precaution that they can,” said Kim.Greg did have an underlying condition: high blood pressure. A Gofundme campaign has been set up to help his family with expenses.Taylor Guitars issued the following statement:“Everyone at Taylor Guitars is heartbroken by the loss of Gregory Denny. For the last 6 years, he came to work with a smile, bringing joy and professionalism to his job. Today Taylor is safer and better equipped to handle emergency situations because of Gregory’s leadership as our security specialist. He was a great co-worker and friend, and we will all miss him.” 2227

KANSAS CITY, Mo. – After more than a century embedded beneath the paint, researchers discovered a grasshopper beneath the brushstrokes in a Vincent Van Gogh painting at the Nelson Atkins Art Museum.Paintings Conservator Mary Schafer discovered the tiny grasshopper in the lower foreground of the landscape while working under a microscope. It is not easily seen by the naked eye.Photo courtesy of the Nelson-Atkins. According to a news release from the Nelson, Schafer and other researchers hoped the grasshopper could be used to determine a more specific date on the painting.“It is not unusual to find insects or plant material in a painting that was completed outdoors,” Schafer said. “But in this case, we were curious if the grasshopper could be used to identify the particular season in which this work was painted.”Unfortunately, entomologists were unable to date the painting, but could determine the grasshopper had died before landing on Van Gogh’s canvas.Additional research on Van Gogh’s “Olive Trees” is underway. The painting is available for viewing at the Nelson Atkins Museum of Art in Kansas City, Missouri.  1144
