BALTIMORE - Food safety experts are warning parents to be mindful when packing perishables like sandwiches and yogurts in your child's lunch.Tanya Brown with the United States Department of Agriculture (USDA) said you're looking at a two-hour window before those brown bag lunches become breeding grounds for bacteria.“You should not put perishable items like bologna sandwiches, turkey sandwiches, cheese or yogurt in a brown paper bag and send a child to school with it,” Brown said.Foods can hit the "danger zone," or temperatures between 40-140 degrees Fahrenheit, when it’s left out of refrigeration over two hours. After four hours, the food item should be tossed.“You want to make sure you put them in an insulated lunch bag with at least two cold sources and those two cold sources could be a frozen water bottle or frozen juice packs or gel packs in there. So, you want to put those perishable items in there and make sure the child does not open the bag and keep opening and closing the bag before lunchtime,” said Brown.If you're sending them with something hot, use a thermos, and warm it up first.“The best way to prepare it is to pour boiling hot water into the thermos first, then discard the hot water and then put the hot soup or stew in there. Make sure it's at 165 degrees Fahrenheit,” Brown said.However, the leading cause of sickness is poor hand washing. Brown said this is an easy problem to solve:“Oftentimes, children don't get an opportunity to wash their hands before they go to lunch and just to trigger their memory put a moist toilette in there or some hand sanitizer to remind them before they start to eat their lunch,” she said.Click here for more information on the danger zone and safe handling of food. 1751

As the end of an incredibly contentious and the heated 2020 election season ends, new research suggests that Americans are more susceptible to falling prey to disinformation depending on which state they call home.For months, Bhaskar Chakravorti and his team at the Global Business School at Tufts University have been analyzing how misinformation has been spreading during this election cycle. Where a person lives often makes them a higher target to everything from fake Facebook accounts to fake Twitter accounts and even fake headlines."We are in extremely more dangerous territory now than we were two years ago," Chakravorti explained.Bad actors, the analysis found, are more likely to target people in states that are either facing hotly contested Presidential or Senate races. Chakravorti says in places like Florida, South Carolina, Kentucky, Montana and Arkansas, voters are more vulnerable to being hit with misinformation. In places like Georgia, Illinois, New Jersey and Minnesota, residents are less likely to be bombarded by false or misleading posts and stories.A person's age, education level and media consumption all weigh into the findings.Chakravorti also says that misinformation is more likely to spread and gain traction on social media."The misinformation is asymmetric in its power,” he explained. “It travels further and faster than truth and facts."Most troublesome right now, the amount of misinformation spreading about voting, from fake stories claiming people can vote after Nov. 3 to false information about mail-in ballot deadlines. Experts also say the spread of misinformation will likely continue long after Election Day.The non-profit Common Cause has also been studying the issue closely."It can result in more uncertainty when there’s already a decrease in the institutional trust and authority that many people feel with their government," said Jesse Littlewood, who works with the group.So, what's the best way to combat misinformation?Do it on the local level. People are more likely to trust information that comes directly from their city or state officials, especially about voting."It’s a real challenge for voters to stay abreast with all that changing information," Littlewood said. 2239

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.

At least three people were killed and a dozen others injured Tuesday after gunfire erupted near a Christmas market in the center of the French city of Strasbourg, French authorities said.Strasbourg police said an armed person entered the perimeter of the Christmas market by the Corbeau Bridge around 8 p.m., heading toward the Rue des Orfèvres. The suspect then opened fire, police said. Police said they have identified the shooter, who remains at large.Here are the latest developments: 497

As states begin to reopen, a new stage in the pandemic means elective surgeries are back on schedule.For 51-year-old mother of two Honaire Murillo, the pandemic delayed a much needed spinal surgery.“The shooting pains all the time and you know I had kids I have to run around. And so, it took about a year and I was so disappointed,” says Murillo.Twenty-four years ago, the aspiring pro-bodybuilder’s dreams were cut short when she was hit by a motorboat while visiting Puerto Rico on business.More than 20 surgeries later, Murillo needed another one.“The pain started coming back and so I knew I was going to have more surgery,” she says.Last week, doctors at Rush University Medical Center’s Midwest Orthopaedics in Chicago were able to get Murillo into surgery for a first-of-its-kind procedure.It was a minimally invasive spine surgery that utilized augmented reality.“The efficiency this provides because of the accuracy and the visualization of the spine is remarkable,” says Dr. Frank Phillips, the director and minimally invasive spinal surgeon at Rush who performed the procedure.A headset guidance system allowed Dr. Phillips to see Murillo’s spinal anatomy – essentially giving him X-ray vision.“That's exactly what it is,” says Dr. Phillips. “It really is X-ray vision. Except it's not just X-ray vision, you're actually seeing the real spine through the skin.”The CT scanned images are directly projected onto the surgeon’s retina and then superimposed right on top of the patient’s surgical area.“I was just blown away,” says Dr. Phillips. “The minute I put my headset on and looked down at the spine it was like that wow moment. I was like ‘this is crazy.’”Researchers say the FDA-cleared x-vision system could revolutionize the way surgeons perform complex procedures.“It's so accurate so precise the visualization so good you can do the surgery more efficiently which obviously translates into less anesthetic time and advantages to the patient,” says Phillips.For Murillo, who eventually went pro 15 years after her accident, this latest groundbreaking surgery has her thinking about another return to competition.“I'm still looking to see if I could comeback one more time. I'm not sure. But, yeah to me it's a dream.”Augmedics, the maker of the technology says it plans to explore the x-ray vision technology beyond just spinal surgery. 2365
