Millions of American children are spending this fall semester taking at least some of their classes online, through Zoom, Google Meet and other platforms.And while many of the bugs, glitches and surprise Zoom "bombings" of this past spring have been fixed, experts say many threats remain.Arneesha Collins, parent of an elementary-aged boy, worries what her son is exposed to when she is not watching."I already don't want my son on the iPad or computer a lot," she said, "because when he gets on there he is already on YouTube."Laura Pipitone has two young children doing some learning at home, and says the technology is still frustratingly glitch-filled."Especially on the iPads the younger kids get, I have to log out and log back in every session," Pipitone said.She is afraid to leave her youngest one alone long at the computer."Parents are kind of expected to be in the room, so I feel like I am back in kindergarten," she said. "It's hard!"Cyber security expert Dave Hatter says hackers and predators are looking at all those children learning online as prime targets."These sort of threats against children have risen during the pandemic," Hatter said, "because kids are spending a lot of time online. You get things like 'Zoom bombing' where someone is screaming racial epithets or is semi-clothed and shows up in the video."Four things parents can doHatter, the head of Intrust IT, says parents of online learners need to take four basic security steps to ensure their screens are not open to prying eyes.Step 1: He says you should start by making sure your WiFi router is not using the default 1-2-3-4 password, or using a password that every kid in the neighborhood knows by now."It's difficult for parents to stay on top of this, but the bad guys on the other hand learn what the cool thing is, because they know where the kids will be," Hatter said.Step 2: Make sure you do regular updates of your PC and software, which patches holes that hackers will take advantage of."Installing the Windows updates is an absolute must," Hatter said. "But you gotta make sure you are updating Zoom as well, and the other software you are using on these devices."And he says make sure your school is following the latest suggestions for safe Zooming, such as the teacher being in the room at all times, and guests having to be invited in.Step 3: Hatter says you need to talk to your kids. Instruct your children to watch for strangers popping up online trying to befriend them on TikTok, Instagram, or other sites that, face it, kids often visit when class becomes boring."Warn your kids about this sort of thing. Tell them not to give personal info to someone you don't know; never agree to meet someone," he said.Step 4: Consider parental software for younger elementary-age children. Hatter suggests you look at services like Net Nanny, Norton Family Premier, Qustodio, or Kaspersky Safe Kids that limits sites children can visit, and tells you where they have been. (PCMag rates the top parental software program).Some services will also run your computer through a VPN (Virtual Private Network) that encrypts your data, making it almost impossible for a hacker to peek in.Arneesha Collins is happy her school has moved to a hybrid system, with some in-class learning, but can't wait for the days when full-time school returns."I wish they were back in school, yeah," she said.___________________________Don't Waste Your Money" is a registered trademark of Scripps Media, Inc.

Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions.Researchers from Northwestern University looked at a calcium-rich supernova with x-ray imaging, which provided a glimpse into the last month of the star’s life and ultimate explosion.The findings, published in The Astrophysical Journal, suggest a calcium-rich supernova is a compact star that gives off an outer layer of gas as it’s dying. When it explodes, the star’s matter collides with material, emitting bright x-rays.The explosion is so intensely hot and high pressure, it allows nuclear fusion to produce a massive amount of calcium in mere seconds. Typically, a star creates a small amount of calcium slowly by burning helium.Half the calcium in the universe likely came from calcium-rich supernovae.“These events are so few in number that we have never known what produced calcium-rich supernova,” said Wynn Jacobson-Galan, a first-year Northwestern graduate student who led the study. “By observing what this star did in its final month before it reached its critical, tumultuous end, we peered into a place previously unexplored, opening new avenues of study within transient science.”The observed explosion was named SN 2019ehk in the Messier 100 galaxy. If that sounds a little too fantasy, just know it was 55 million light years from earth.“Without this explosion, you wouldn’t know that anything was ever there,” Margutti added. “Not even Hubble could see it.”The team was able to look at images from the Hubble Telescope of the area of SN 2019ehk before the explosion to compare before and after.The researchers are working on a follow-up study that includes how the supernova is evolving after the explosion, according to statements made to CNN. 1821

Meijer is extending its 15 percent teacher discount on classroom essentials – it will now be available for the entire 2020-2021 school year.Additionally, the discount can now be applied to face masks and hand sanitizers."There are so many uncertainties as teachers head back to classes and we've heard the plans may change throughout the year, so our goal is to help them shop with confidence whenever they need to refill supplies," said Brandon Pasch, Director of Back-to-School Merchandising for Meijer, in a press release "We hope that extending the 15 percent discount for the entire school year helps reduce the stress to their pocketbooks as they continue gathering supplies for their classrooms and home offices." Other items available for the discount range from spiral notebooks and schoolroom essentials like Crayola, Elmer's Glue, Sharpies and Post-It Notes to planners and journals, and memo boards.Teachers can get the discount, in the form of a paper coupon, by presenting a current school ID at their local Meijer Customer Service desk. The coupon can only be used for purchases made in-store and some restrictions apply. For more information, visit the Meijer Back to School site. 1204
