A cellphone industry trade group is trying to sell schools on the educational benefits of smartphones in the classroom, and it’s bringing some research of questionable independence to back up its claims. Qualcomm (which makes cellphone chips) paid for a study in a North Carolina school wherein 9th and 10th graders used smartphones in math classes:”The students used the phones for a variety of tasks, including recording themselves solving problems and posting the videos to a private social networking site, where classmates could watch. The study found that students with the phones performed 25 percent better on the end-of-the-year algebra exam than did students without the devices in similar classes.”When I was in high school, the TI-86 was our workhorse in math classes and I’m sure it helped me better understand certain concepts in calculus. And the practice I got writing simple programs for the TI-86 helped later in college in computer science and some branches of analytic philosophy.But the technology was only useful in math and the hard sciences and it’s hard for me to see how a device which can also make phone calls would really improve on a good graphing calculator. What do you think? Do smartphones have smart uses in school?

Man’s dog suddenly becomes protective of his wife, Internet clocks the reason right away
The online community came through in a big way.
Reddit user Girlfriendhatesmefor’s three-year-old pitbull, Otis, had recently become overprotective of his wife. So he asked the online community if they knew what might be wrong with the dog.
“A week or two ago, my wife got some sort of stomach bug,” the Reddit user wrote under the subreddit /r/dogs. “She was really nauseous and ill for about a week. Otis is very in tune with her emotions (we once got in a fight and she was upset, I swear he was staring daggers at me lol) and during this time didn’t even want to leave her to go on walks. We thought it was adorable!”
His wife soon felt better, butthe dog’s behavior didn’t change.
Otis knew before they did. Canva Girlfriendhatesmefor began to fear that Otis’ behavior may be an early sign of an aggression issue or an indication that the dog was hurt or sick.
So he threw a question out to fellow Reddit users: “Has anyone else’s dog suddenly developed attachment/aggression issues? Any and all advice appreciated, even if it’s that we’re being paranoid!”
The most popular response to his thread was by ZZBC.
Any chance your wife is pregnant?

The potential news hit Girlfriendhatesmefor like a ton of bricks. A few days later, Girlfriendhatesmefor posted an update and ZZBC was right!
“The wifey is pregnant!” the father-to-be wrote. “Otis is still being overprotective but it all makes sense now! Thanks for all the advice and kind words! Sorry for the delayed reply, I didn’t check back until just now!”
Redditors responded with similar experiences.
Anecdotal I know but I swear my dog knew I was pregnant before I was. He was super clingy (more than normal) and was always resting his head on my belly.

So why do dogs get overprotective when someone is pregnant?
Jeff Werber, PhD, president and chief veterinarian of the Century Veterinary Group in Los Angeles, told Health.com that “dogs can also smell the hormonal changes going on in a woman’s body at that time.” He added the dog may “not understand that this new scent of your skin and breath is caused by a developing baby, but they will know that something is different with you—which might cause them to be more curious or attentive.”
The big lesson here is to listen to your pets and to ask questions when their behavior abruptly changes. They may be trying to tell you something, and the news may be life-changing.

Why mass shootings spawn conspiracy theories
Mass shootings and conspiracy theories have a long history.
While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.
When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.
Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
