Scientists just made a major bee-vaccination breakthrough. Here's why it's such a big deal.

How do bees vaccinate their babies? Now we know.

By now, you probably know about how amazing bees are and why we need them.

Bees are responsible for making a third of our food possible. From cherries to blueberries to cucumbers to apples and so much more, bees are essential. That, and they're responsible for the world's supply of honey — which in addition to being delicious, can be used to treat wounds because of its awesome medicinal and antibacterial properties.

You might also be aware that bees have been through some rough times lately.

Over the past few years, you may have seen some headlines like this:

Turns out that the die-off of an insect responsible for a massive portion of the world's food supply is enough to make people a little anxious.

But there's some great news! Researchers have made a major discovery that might help us prevent the bees from dying.

It turns out that bees vaccinate their babies against disease by feeding them a special blood protein called vitellogenin. Before this discovery, we basically had no idea how adult bees transferred disease immunity to their larvae.

"The process by which bees transfer immunity to their babies was a big mystery until now. What we found is that it's as simple as eating," said Gro Amdam, an Arizona State University School of Life Sciences professor and co-author of the study. "Our amazing discovery was made possible because of 15 years of basic research on vitellogenin."

Bee vaccinations work a bit like this:

Worker bees head out into the world to pollinate plants, build the honeycomb, and do other bee-related activities. They also are responsible for making food for the queen from the pollen they collect. The food contains bacteria, and when the queen eats, the bacteria is stored. The bacteria travels to developing eggs, and as a result, baby bees are born with immunity against some common diseases.

But why should we care? Remember how I mentioned that bees are pretty important and we need to protect them? That.

Now that we know how bee vaccination works, we can start working on man-made insect vaccines to stave off colony collapse disorder and other challenges facing our honey-producing friends. Science is awesome.

Long live the bees!

If you're a woman and you want to be a CEO, you should probably think about changing your name to "Jeffrey" or "Michael." Or possibly even "Michael Jeffreys" or "Jeffrey Michaels."

According to Fortune, last year, more men named Jeffrey and Michael became CEOs of America's top companies than women. A whopping total of one woman became a CEO, while two men named Jeffrey took the title, and two men named Michael moved into the C-suite as well.

The "New CEO Report" for 2018, which looks at new CEOS for the 250 largest S&P 500 companies, found that 23 people were appointed to the position of CEO. Only one of those 23 people was a woman. Michelle Gass, the new CEO of Kohl's, was the lone female on the list.

How much of what we do is influenced by what we see on TV? When it comes to risky behavior, Netflix isn't taking any chances.

After receiving a lot of heat, the streaming platform is finally removing a controversial scenedepicting teen suicide in season one of "13 Reasons Why. The decision comes two years after the show's release after statistics reveal an uptick in teen suicide.

"As we prepare to launch season three later this summer, we've been mindful about the ongoing debate around the show. So on the advice of medical experts, including Dr. Christine Moutier, Chief Medical Officer at the American Foundation for Suicide Prevention, we've decided with creator Brian Yorkey and the producers to edit the scene in which Hannah takes her own life from season one," Netflix said in a statement, per The Hollywood Reporter.

At Trump's 'Social Media Summit' on Thursday, he bizarrely claimed Arnold Schwarzenegger had 'died' and he had witnessed said death. Wait, what?!


He didn't mean it literally - thank God. You can't be too sure! After all, he seemed to think that Frederick Douglass was still alive in February. More recently, he described a world in which the 1770s included airports. His laissez-faire approach to chronology is confusing, to say the least.

Words matter. And they especially matter when we are talking about the safety and well-being of children.

While the #MeToo movement has shed light on sexual assault allegations that have long been swept under the rug, it has also brought to the forefront the language we use when discussing such cases. As a writer, I appreciate the importance of using varied wording, but it's vital we try to remain as accurate as possible in how we describe things.

There can be gray area in some topics, but some phrases being published by the media regarding sexual predation are not gray and need to be nixed completely—not only because they dilute the severity of the crime, but because they are simply inaccurate by definition.

One such phrase is "non-consensual sex with a minor." First of all, non-consensual sex is "rape" no matter who is involved. Second of all, most minors legally cannot consent to sex (the age of consent in the U.S. ranges by state from 16 to 18), so sex with a minor is almost always non-consensual by definition. Call it what it is—child rape or statutory rape, depending on circumstances—not "non-consensual sex."
