With a .6 billion Mega Millions jackpot up for grabs Tuesday night, lottery players across the country are no doubt looking for any edge they can get.Disclaimer: Your odds of winning the Mega Millions jackpot are 1 in 302,575,350, no matter which numbers you pick or where you buy your tickets.Mathematicians say the simplest way to increase your odds is to buy more tickets. Think about it: Two tickets give you twice the chance (though your odds are still minimal), and buying 100 million tickets would give you a 100 million chances (but you could still lose, and lose 0 million in the process).Whatever you do, don't overspend. Mega Millions reminds players that gambling can be addictive and very damaging. The information below is presented solely for entertainment purposes only, and the E.W. Scripps Co. is not responsible for any losses incurred by using the following tips.  947

When students of Marjory Stoneman Douglas return to class after spring break next week, they'll be required to carry clear backpacks.The move is meant to ramp up security measures after last month's deadly shooting and a series of breaches since then."Clear backpacks are the only backpacks that will be permitted on campus," said Broward County School Superintendent Robert Runcie said in a letter sent to parents. 423

While many think of NASA as the government agency that sends scientists into space, some of NASA’s most important work frequently is used to help people on Earth.In recent months, NASA has used its extensive network of scientists and researchers to combat the coronavirus. And in short order, the agency provided patients and healthcare providers with tools that may have been used to save lives.This week, NASA outlined a number of innovations the agency developed to support the fight against the virus.NASA created an open source for N95 respirators so people can make their own masks by using 3D printers. N95 respirators are unique as they protect the wearer from the virus. NASA’s designs were engineered to meet or exceed standard N95 performance, can be used for different purposes, are compatible with commercially-available filters, and do not disrupt the supply chain.If you have access to a 3D printer, here is how to create an N95 respirator designed by NASA.In addition to NASA’s open-source N95 respirators, the team from Johnson Space Center developed and tested a sterilization protocol to combat a national shortage of N95 masks. This allows N95 respirators to be reused by healthcare providers.“I had a very deep and personal connection to the evaluation (of N95 masks), because my wife is a medical professional… on the frontlines, with only one mask allocated for her to use and re-use daily,” said NASA engineer and project lead Jeremy Jacobs. “She has been very concerned about cross contamination between patient-to-patient and to our family.”Among other innovations, NASA’s Jet Propulsion Laboratory in California designed a new high-pressure ventilator tailored specifically to treat COVID-19 patients. It was designed to treat patients who might not require a full-featured ventilator, keeping the nation’s limited supply of traditional ventilators available, NASA said.NASA’s Armstrong Flight Research Center in California joined several other agencies to create a helmet that functions like a continuous positive airway pressure, commonly known as CPAP, machine to force oxygen into a patient’s low-functioning lungs. 2156

While the Centers for Disease Control and Prevention is urging Americans not to travel this holiday season, it's clear that many will choose to do so anyway.Between Nov. 25 and Nov. 29 — the height of the Thanksgiving travel surge —the Transportation Security Agency (TSA) said it screened about 4.5 million travelers. While that represented 39% less travelers than last year, it represented the most travelers the agency had screened since the start of the pandemic.With another surge in travel expected for Christmas and New Year's, the TSA has offered some helpful tips when it comes to packing luggage for the holiday season.Packing giftsDo not pre-wrap gifts: Gifts need to be screened like any other piece of luggage, meaning gifts need to be unwrapped if they need to be inspected. The TSA suggests wrapping once you reach your destination, or wrapping in a gift bag.Be sure to pack gifts that contain large amounts liquid, like perfumes, gel candles or snow globes, in a checked bag. TSA allows containers with 3.4 ounces of liquid or less for carry-ons.Snowboards, snowshoes and ice skates can be carried on, but be sure to check with airlines about a plane's overhead bin space. Skis and ski poles will need to be checked.Packing foodHomemade baked goods and other treats can be carried on, but any sort of jams, jellies or syrups are liquids and should be checked if they're in a container larger than 3.4 ounces. A rule of thumb? "If you can spill it, spray it, spread it, pump it or pour it, then it should be packed in a checked bag if the container is larger than 3.4 ounces."Higher-proof alcoholic beverages (between 24% and 70% alcohol by volume) are limited in check bags to five liters a passenger. Any beverage with less than 24% alcohol by volume has no size limit in a checked bag.Mini bottles of alcohol can be carried on, as long as they are less than 3.4 ounces and fit "comfortably" in a single quart-sized bag.Packing electronics Electronics to be given as a gift can be carried on, but remember to place electronics larger than a laptop in their own bin with nothing above or below it.TSA allows drones past checkpoints, but double-check with airlines on their policies about transporting drones.Remember, loose lithium batteries are prohibited in checked bags.

When we hear our phone go off and see an unknown number, we're not very likely to answer, but that habit is creating some issues for contact tracers.People are hired to get in touch with anyone who's been in contact with someone who has been diagnosed with COVID-19.With people not answering calls from contact tracers, controlling the coronavirus becomes more difficult.But it doesn't mean contact tracers give up.“In some cases, when contact tracers call someone, and that person is uncomfortable talking to them on the phone, in some counties, they will actually send someone to that person's home to conduct an in-person interview, if they're more comfortable doing that,” said Steve Waters, founder and CEO of CONTRACE.Even when contact tracers do manage to get someone on the phone, it can be difficult to get information from them. This is a result of all the spam calls trying to scam people.That's why contact tracers say it's all about establishing trust in that cold call.“If you have a cultural understanding of the people that you are calling, that goes a long way to begin with,” said Waters. “I think you are more likely to be trusting of someone who has the demeanor and cultural understanding of your region, than somewhere across the country.”CONTRACE was founded when coronavirus cases started popping up in the U.S. It helps public and private groups with contact tracing efforts.The group encourages every state and local government to work with phone providers to help people know that calls are coming from contact tracers.Ideally, the call would be identified as the local health department or contact tracing program. 1650
