Thanks to a new invention, sponges may soon help save shooting victims.

After getting FDA approval, this handy device will soon be making its way to first responders.

While debate over how to reduce gun violence carries on, there's a new tool that might, at least, help victims of it.

It's called the XSTAT, and it's a wonderful, ridiculously simple invention that's sure to save lives in coming years.

Invented by John Steinbaugh, a former U.S. Army special forces medic, XSTAT was the result of a request from the Army for something to replace gauze, the go-to battlefield wound-packer for decades. Steinbaugh decided to see whether it'd be possible to replace gauze with sponges that can both absorb blood and apply pressure to gunshot or shrapnel wounds.


Here he is discussing his invention in a 2014 episode of "PBS NewsHour."


Simple! Effective! Life-saving! GIF from "PBS NewsHour."

Sponges are injected into the wound, clotting the blood.

The sponges are coated with blood-clotting chemicals and have been shown to stop bleeding after just 20 seconds (as opposed to three to five minutes with gauze).

Here's what it looks like in action. (Pretend that the opening in this Erlenmeyer flask is a bullet wound and the blue liquid is blood.)

This helps buy precious time to get the victim to a surgeon.

As Dr. Martin Schreiber — chief of trauma at the Oregon Health and Science University and colonel in the Army Reserve — tells PBS, the difference between 20 seconds and three minutes can mean the difference between life and death.

"According to the United States Army Institute of Surgical Research, 30 to 40 percent of civilian deaths by traumatic injury are the result of hemorrhaging," reads the FDA's notice of approval for the XSTAT 30 (the version made for first responders, paramedics, police officers, and the like). "Of those deaths, 33 to 56 percent percent occur before the patient reaches a hospital."

Of course, the XSTAT is not a cure-all. There are some catches involved.

For one, certain factors like the size and shape of the wound will determine whether the XSTAT 30 is the most effective option. And, of course, this is merely to help buy time for a victim to get to a hospital, at which point the sponges (marked with an "X" that will show up on X-rays) need to be removed.

But it's a quick, simple update to some old technology.

If there's one thing we can take away from this invention, it's that solutions don't always need to be sophisticated.

Sometimes the best inventions and innovations come from the simplest ideas. For example, take this gravity-powered light that's been popping up in countries where electricity is scarce.

Behold! The gravity light! GIF from Therefore.

So whether it's updating a battlefield staple like gauze or using forces of nature to stand in for electricity, look around! You never know where the next great invention will come from.

Mom and blogger Mary Katherine Backstrom regularly shares snippets of life with her two children on her Facebook page. One particularly touching interaction with her daughter is melting hearts and blowing minds due to the three-year-old's wise words about forgiveness.

Even adults struggle with the concept of forgiveness. Entire books have been written about how and why to forgive those who have wronged us, but many still have a hard time getting it. Who would guess that a preschooler could encapsulate what forgiveness means in a handful of innocent words?

California has a housing crisis. Rent is so astronomical, one San Francisco company is offering bunk bedsfor $1,200 a month; Google even pledged$1 billion to help tackle the issue in the Bay Area. But the person who might fix it for good? Kanye West.

The music mogul first announced his plan to build low-income housing on Twitter late last year.

"We're starting a Yeezy architecture arm called Yeezy home. We're looking for architects and industrial designers who want to make the world better," West tweeted.

The U.S. women's soccer team won the Women's World Cup, but the victory is marred by the fact that the team is currently fighting for equal pay. In soccer, the game is won by scoring points, but the fight for equal pay isn't as clearly winnable and the playing field isn't as even.

We live in a world where winning the World Cup is easier than winning equal pay, but co-captain Megan Rapinoe says there's one easy way fans can support the team: Go see games.

Some people argue the men's team deserves to get paid more because they are more successful and earn more money for the United States Soccer Federation. Pay depends on merchandise and ticket sales, and in general, men's sporting events tend to draw a bigger crowd than women's sporting events. It's not about sex, many argue; it's about the fact that people just prefer to see men play.

You think you know someone pretty well when you spend years with them, but, as we've seen time and again, that's not always the case. And though many relationships don't get to a point where the producers of "Who the (Bleep) Did I Marry?" start calling every day just to chat, the reality is that sometimes partners will reveal shocking things even after you thought you'd been all shocked out.

That's the case for one woman whose Reddit thread has recently gone viral. The 25-year-old, who's been with her boyfriend for five years, took to a forum for relationship advice to ask if it was normal that her seemingly cool and loving boyfriend recently revealed women shouldn't have a fundamental right. (And no, it's not abortion — although there are a lot of "otherwise best ever boyfriends" out there who want to deny women the rights to bodily autonomy, too.)
