Doctors just used HIV to cure 'bubble boy' disease.

Remember the Bubble Boy from the '70s?

One of the more famous cases in medical science, David Vetter was born in 1971 with severe combined immunodeficiency (SCID), which made him extremely vulnerable to germs and disease. So, 20 seconds after he was born, he was put into a sealed, plastic chamber. He remained in there until the age of six at which point he was given a plastic suit designed by NASA so he could move around more freely. Still, a plastic shield separated him from the rest of the world until he died at age 12 after a bone marrow transplant, one of the only other known treatments for the disease, failed.

While the bone marrow transplant may have helped, it doesn't cure SCID, and and can even lead to more complications.

Today, however, a true cure for SCID is within reach. And it comes from an usual place — another infamous disease.

According to new research that was developed at a Tennessee hospital, when scientists collected bone marrow from babies with SCID and corrected the defect gene with an altered version of an HIV gene, the disease was eradicated.

Most babies that formerly had the SCID gene were discharged from the hospital after one month, declared SCID-free.

Since then, they appear to be living healthy lives out in the world, free from their confining plastic protection.

"These patients are toddlers now, who are responding to vaccinations and have immune systems to make all immune cells they need for protection from infections as they explore the world and live normal lives," Dr Ewelina Mamcarz of St Jude, an author of the study, said in a statement.

This isn't to say that HIV should now be regarded with reverence, but this medical first just goes to show,  incredible discoveries can be born from anywhere — even a potentially deadly disease.

Recent tragic mass shootings in El Paso and Dayton have sparked a lot of conversation and action on the state level over the issue of gun control. But none may be as encouraging as the most recent one, in which 145 CEOs signed a letter urging the U.S. Senate to take action at their level.

The fine folks at Forbes are currently falling all over themselves trying to clean up the mess they created by publishing their 2019 list of 100 Most Innovative Leaders.

The problem: The list included 99 men and one woman. For those not so good with the math, that means according to Forbes, only 1% of the country's most innovative leaders are female.

Have you ever watched a movie that's so abysmally bad that you wonder how it ever even got made? Where you think, "Hundreds and hundreds of people had to have been directly involved in the production of this film. Did any of them ever think to say, 'Hey, maybe we should just scrap this idea altogether?"

That's how it feels to see a list like this. So how did Forbes come up with these results?

There's something delicious and addicting about those trendy recipe videos circulating online. You've seen them before: the quick and beautiful play-by-plays of mouthwatering dishes you wish you were eating at this very moment.

The recipes seem so simple and magical and get you thinking, "Maybe I can make that five-cheese bacon lasagna tonight." And before you know it, you're at the store loading up on Colby-Monterey Jack (or is that just me?).

For some families, though, the ingredients and final product look a little different. As part of Hunger Action Month, the hunger-relief organization Feeding America is using our obsession with cooking videos to highlight the reality many food-insecure families face when they sit down for dinner: hunger, and no food in sight.

By putting a twist on the bite-sized food videos all over the internet, they hope to raise awareness that hunger is an unacceptable reality for too many families.
