A rover dived to the bottom of the ocean — again. 15 photos show what it discovered.

Back in 2016, this is what we saw on the ocean floor.

It was found by this little dude:

That's the Deep Discoverer remotely operated vehicle, or ROV, that lives on the Okeanos Explorer, a NOAA research ship that studies the oceans and climate change. The ship's expedition last year to the Mariana Islands revealed an unfortunate sight — beer cans, plastic bags, and other man-made trash littering the sea floor.

This year, the ship's gone out again. The good news: So far, none of its daily updates has included cans of processed meat.

Instead, its deepwater dives off the coast of American Samoa and various marine protected areas have revealed an amazing menagerie of ocean critters.

1. Creatures like this long-armed squid photographed off the coast of Swains Island.

2. This might look like a bit of rubbish, but trust me, it's a barrel sponge and it's very much alive.

It fell over though. Oh, pathos!

3. A pair of sixgill sharks out for a swim together.‌

4. A little oreo fish!

Unfortunately (fortunately?) they don't have anything to do with the cookies. Their scientific genus Oreosoma means "mountain body." They got the name because of all their little spikes.

5. But the ocean's much stranger than a fish whose name sounds like a cookie. Check out this ridiculous crinoid.

Though it might look like the worst bouquet ever, crinoids are, in fact, animals related to starfish.

6. Or this shrimp hiding in a glass sponge.

It looks like the cover art of a science-fiction novel.

7. Ever seen an octopus egg case?

The brown sac is the outer case, while the purple dangly bit is what's known as the chorion and hides the embryo.

8. Maybe it'll grow up to look like this magnificent specimen.

The rare Grimpoteuthis, also known as the Dumbo octopus, uses the flaps on the side of it's head to swim through the water.

9. Or check out this ... what is this? A sea cucumber? Jerry, is this a sea cucumber?

Jerry says it is and belongs to the Psychropotes genus. Thanks, Jerry!

10. Not all sea cucumbers look like God's rough drafts though. Check out this elegant swimmer.

This little one will likely spend it's entire life swimming around, catching food from the currents.

11. Scientists couldn't decide whether these crabs were fighting or flirting.

Spotted nearly 2,500 feet below the surface, this hand-holding could be either premating behavior or aggression.

12. This shrimp was definitely guilty of murder though. It was a murdering shrimp. The murdershrimp.

It totally caught and ate a fish on camera. Listen man, I don't want any trouble. You can have that fish; just leave me and my family alone.

13. Let's leave the murdershrimp behind and focus on something a bit more wholesome, like this cute little jellyfish.

Scientists spotted this little Narcomedusae jelly about 1,800 feet down.

14. OK, enough of the cute. Time for monsters again. Meet the chimaera.

Chimaeras, also known as ghost fish, are related to sharks and live on the deep ocean floor. This one was found more than a mile under the surface.

15. Believe it or not, that wasn't the weirdest looking fish they found. You've really got to see this armored searobin in motion.

It's like a fish trying to cosplay as a Star Wars A-wing.

The ocean is full of such amazing life. But here's the thing: The trash is still out there too.

Those beer cans and Spam containers haven't gone away. Nobody's going along the Mariana trench with a recycling bag. And there are more subtle ways our waste affects the ocean as well. A study published in February 2017, for instance, found man-made chemicals invading the bodies of even the deepest ocean fauna.

These are (still) the kinds of images people should see. The ocean is an amazing place. Let's keep it that way.

(Because I seriously don't want that murdershrimp coming after me.)

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.

The fasting period of Ramadan observed by Muslims around the world is a both an individual and communal observance. For the individual, it's a time to grow closer to God through sacrifice and detachment from physical desires. For the community, it's a time to gather in joy and fellowship at sunset, breaking bread together after abstaining from food and drink since sunrise.

The COVID-19 pandemic has limited group gatherings in many countries, putting a damper on the communal part of Ramadan. But for one community in Barcelona, Spain, a different faith has stepped up to make the after sunset meal, known as Iftar, as safe as possible for the Muslim community.

According to Reuters, Father Peio Sanchez, Santa Anna's rector, has opened the doors of the Catholic church's open-air cloisters to local Muslims to use for breaking the Ramadan fast. He sees the different faiths coming together as a symbol of civic coexistence.

"I love being a nurse because I have the honor of connecting with my patients during some of their best and some of their worst days and making a difference in their lives is among the most rewarding things that I can do in my own life" - Tenesia Richards, RN

From ushering new life into the world to holding the hand of a patient as they take their last breath, nurses are everyday heroes that deserve our respect and appreciation.

To give back to this community that is always giving so selflessly to others, CeraVe® put out a call to nurses to share their stories for a chance to be featured in Heroes Behind the Masks, a digital content series shining a light on nurses who go above and beyond to provide safe and quality care to patients and their communities.

First up: Tenesia Richards, a labor and delivery nurse working in New York City who, in addition to her regular job, started a community outreach program in a homeless shelter that houses expectant mothers for up to one year postpartum.

Upon learning at a conference that black mothers in the U.S. die at three to four times the rate of white mothers, one of the widest of all racial disparities in women's health, Richards decided to take further action to help her community. She, along with a handful of fellow nurses, volunteered to provide antepartum, childbirth and postpartum education to the women living at the shelter. Additionally, they looked for other ways to boost the spirits of the residents, like throwing baby showers and bringing in guest speakers. When COVID-19 hit and in-person gatherings were no longer possible, Richards and her team found creative workarounds and created holiday care packages for the mothers instead.
