There are so many wonderful museums to explore all around the world that it would take a lifetime to visit them all—but it only takes a few minutes to visit one online. Many of the top science museums reach out to long-distance fans through their Instagram accounts, which are playgrounds of knowledge and wonder. Here are seven of our favorites.

1. AMERICAN MUSEUM OF NATURAL HISTORY // NEW YORK, NY

New York City's American Museum of Natural History is one of those places you could spend weeks exploring and still not see everything they have to offer. That’s why you should follow their Instagram feed, which is like an online museum that rotates through different subjects every day. The feed features theme days like Trilobite Tuesday and Fossil Friday, with plenty of information to go with each image.

2. EXPLORATORIUM // SAN FRANCISCO, CA

The Exploratorium in San Francisco is more than just a science museum—it’s a hands-on learning experience for people all ages. But if you can’t make it to the West Coast, many of the museum's experiences are shared in video form on the Exploratorium’s Instagram feed, including footage of Dutch artist Theo Jansen’s Strandbeest kinetic sculpture creations walking around. 

3. SCIENCE MUSEUM OF MINNESOTA // SAINT PAUL, MN

For more than 100 years, the Science Museum of Minnesota has offered fun and educational exhibits for all ages. You won’t miss a taste of any of them when you follow the museum’s Instagram feed. Even past exhibits, like Mummies and Jerusalem, are available for your perusal online.

4. MUSEUM OF SCIENCE // BOSTON, MA

Boston's Museum of Science is one of the premier American museums promoting science and technology. In addition to public exhibitions, the museum offers educational programs and teacher resources, traveling exhibits, private events, overnight field trips, and awards and recognition for those who contribute to the fields of science and technology. Every Sunday, the museum’s Instagram feed features a different scientist with an inspirational quote for #ScienceQuoteSunday, with an emphasis on women in STEM fields. In between, there’s plenty of science to learn and exhibits to see.

5. NATIONAL AIR AND SPACE MUSEUM // WASHINGTON, D.C.

 

The National Air and Space Museum in Washington, D.C., is part of the Smithsonian Institution. For the rest of this year, it’s a pilgrimage site for Star Trek fans as they celebrate the 50th anniversary of the original series. The flagship exhibition, so to speak, is the newly-restored original TV model of the starship Enterprise. You can see the process of the model’s restoration and keep abreast of Star Trek events on Instagram.

6. MÜTTER MUSEUM // PHILADELPHIA, PA

The Mütter Museum asks, “Are you ready to be disturbingly informed?” The Philadelphia institution houses tributes to the strange and often overlooked parts of the history of biology and medical science, which means their exhibits are often morbid. But it's also a treasure trove of things you won’t find in other museums. The museum’s Instagram account offers a look at exhibitions like the permanent Hyrtl Skull Collection, which inspired photographer David Orr’s "Perfect Vessels" series, on exhibit now at the Mütter. (The picture above was taken while Orr was photographing the museum’s skulls for his project.) Each photo in the Mütter's feed comes with a fascinating history, such as the skull that shows evidence of a lobotomy.

7. THE TECH MUSEUM OF INNOVATION // SAN JOSE, CA

A Samba drumming team is outside welcoming guests as they arrive for our Members Party tonight! Can you hear them, #DTSJ?

8 Tricks to Help Your Cat and Dog to Get Along

When people aren’t debating whether cats or dogs are more intelligent, they’re equating them as mortal foes. That’s a stereotype that both cat expert Jackson Galaxy, host of the Animal Planet show My Cat From Hell, and certified dog trainer Zoe Sandor want to break.

Typically, cats are aloof and easily startled, while dogs are gregarious and territorial. This doesn't mean, however, that they can't share the same space—they're just going to need your help. “If cats and dogs are brought up together in a positive, loving, encouraging environment, they’re going to be friends,” Galaxy tells Mental Floss. “Or at the very least, they’ll tolerate each other.”

The duo has teamed up in a new Animal Planet series, Cat Vs. Dog, which airs on Saturdays at 10 p.m. The show chronicles their efforts to help pet owners establish long-lasting peace—if not perfect harmony—among cats and dogs. (Yes, it’s possible.) Gleaned from both TV and off-camera experiences, here are eight tips Galaxy and Sandor say will help improve household relations between Fido and Fluffy.

1. TAKE PERSONALITY—NOT BREED—INTO ACCOUNT.

Contrary to popular belief, certain breeds of cats and dogs don't typically get along better than others. According to Galaxy and Sandor, it’s more important to take their personalities and energy levels into account. If a dog is aggressive and territorial, it won’t be a good fit in a household with a skittish cat. In contrast, an aging dog would hate sharing his space with a rambunctious kitten.

If two animals don’t end up being a personality match, have a backup plan, or consider setting up a household arrangement that keeps them separated for the long term. And if you’re adopting a pet, do your homework and ask its previous owners or shelter if it’s lived with other animals before, or gets along with them.

2. TRAIN YOUR DOG.

To set your dog up for success with cats, teach it to control its impulses, Sandor says. Does it leap across the kitchen when someone drops a cookie, or go on high alert when it sees a squeaky toy? If so, it probably won’t be great with cats right off the bat, since it will likely jump up whenever it spots a feline.

Hold off Fido's face time with Fluffy until the former is trained to stay put. And even then, keep a leash handy during the first several cat-dog meetings.

3. GIVE A CAT ITS OWN TERRITORY BEFORE IT MEETS A DOG.

Cats need a protected space—a “base camp” of sorts—that’s just theirs, Galaxy says. Make this refuge off-limits to the dog, but create safe spaces around the house, too. This way, the cat can confidently navigate shared territory without trouble from its canine sibling.

Since cats are natural climbers, Galaxy recommends taking advantage of your home’s vertical space. Buy tall cat trees, install shelves, or place a cat bed atop a bookcase. This allows your cat to observe the dog from a safe distance, or cross a room without touching the floor.

And while you’re at it, keep dogs away from the litter box. Cats should feel safe while doing their business, plus dogs sometimes (ew) like to snack on cat feces, a bad habit that can cause your pooch to contract intestinal parasites. These worms can cause a slew of health problems, including vomiting, diarrhea, weight loss, and anemia.

Baby gates work in a pinch, but since some dogs are escape artists, prepare for worst-case scenarios by keeping the litter box uncovered and in an open space. That way, the cat won’t be cornered and trapped mid-squat.

4. EXERCISE YOUR DOG'S BODY AND MIND.

“People exercise their dogs probably 20 percent of what they should really be doing,” Sandor says. “It’s really important that their energy is released somewhere else so that they have the ability to slow down their brains and really control themselves when they’re around kitties.”

Dogs also need lots of stimulation. Receiving it in a controlled manner makes them less likely to satisfy it by, say, chasing a cat. For this, Sandor recommends toys, herding-type activities, lure coursing, and high-intensity trick training.

“Instead of just taking a walk, stop and do a sit five times on every block,” she says. “And do direction changes three times on every block, or speed changes two times. It’s about unleashing their herding instincts and prey drive in an appropriate way.”

If you don’t have time for any of these activities, Zoe recommends hiring a dog walker, or enrolling in doggy daycare.

5. LET CATS AND DOGS FOLLOW THEIR NOSES.

In Galaxy's new book, Total Cat Mojo, he says it’s a smart idea to let cats and dogs sniff each other’s bedding and toys before a face-to-face introduction. This way, they can satisfy their curiosity and avoid potential turf battles.

6. PLAN THE FIRST CAT/DOG MEETING CAREFULLY.

Just like humans, cats and dogs have just one good chance to make a great first impression. Luckily, they both love food, which might ultimately help them love each other.

Schedule the first cat-dog meeting during mealtime, but keep the dog on a leash and both animals on opposite sides of a closed door. They won’t see each other, but they will smell each other while chowing down on their respective foods. They’ll begin to associate this smell with food, thus “making it a good thing,” Galaxy says.

Do this every mealtime for several weeks, before slowly introducing visual simulation. Continue feeding the cat and dog separately, but on either side of a dog gate or screen, before finally removing it all together. By this point, “they’re eating side-by-side, pretty much ignoring each other,” Galaxy says. For safety’s sake, continue keeping the dog on a leash until you’re confident it’s safe to take it off (and even then, exercise caution).

7. KEEP THEIR FOOD AND TOYS SEPARATE.

After you've successfully ingratiated the cat and dog using feeding exercises, keep their food bowls separate. “A cat will walk up to the dog bowl—either while the dog’s eating, or in the vicinity—and try to eat out of it,” Galaxy says. “The dog just goes to town on them. You can’t assume that your dog isn’t food-protective or resource-protective.”

To prevent these disastrous mealtime encounters, schedule regular mealtimes for your pets (no free feeding!) and place the bowls in separate areas of the house, or the cat’s dish up on a table or another high spot.

Also, keep a close eye on the cat’s toys—competition over toys can also prompt fighting. “Dogs tend to get really into catnip,” Galaxy says. “My dog loves catnip a whole lot more than my cats do.”

8. CONSIDER RAISING A DOG AND CAT TOGETHER (IF YOU CAN).

Socializing these animals at a young age can be easier than introducing them as adults—pups are easily trainable “sponges” that soak up new information and situations, Sandor says. Plus, dogs are less confident and smaller at this stage in life, allowing the cat to “assume its rightful position at the top of the hierarchy,” she adds.

Remain watchful, though, to ensure everything goes smoothly—especially when the dog hits its rambunctious “teenage” stage before becoming a full-grown dog.

10 Juicy Facts About Sea Apples

They're both gorgeous and grotesque. Sea apples, a type of marine invertebrate, have dazzling purple, yellow, and blue color schemes streaking across their bodies. But some of their habits are rather R-rated. Here’s what you should know about these weird little creatures.

1. THEY’RE SEA CUCUMBERS.

The world’s oceans are home to more than 1200 species of sea cucumber. Like sand dollars and starfish, sea cucumbers are echinoderms: brainless, spineless marine animals with skin-covered shells and a complex network of internal hydraulics that enables them to get around. Sea cucumbers can thrive in a range of oceanic habitats, from Arctic depths to tropical reefs. They're a fascinating group with colorful popular names, like the “burnt hot dog sea cucumber” (Holothuria edulis) and the sea pig (Scotoplanes globosa), a scavenger that’s been described as a “living vacuum cleaner.”

2. THEY'RE NATIVE TO THE WESTERN PACIFIC OCEAN.

Sea apples have oval-shaped bodies and belong to the genus Pseudocolochirus and genus Paracacumaria. The animals are indigenous to the western Pacific, where they can be found shuffling across the ocean floor in shallow, coastal waters. Many different types are kept in captivity, but two species, Pseudocolochirus violaceus and Pseudocolochirus axiologus, have proven especially popular with aquarium hobbyists. Both species reside along the coastlines of Australia and Southeast Asia.

3. THEY EAT WITH MUCUS-COVERED TENTACLES.

Sea cucumbers, the ocean's sanitation crew, eat by swallowing plankton, algae, and sandy detritus at one end of their bodies and then expelling clean, fresh sand out their other end. Sea apples use a different technique. A ring of mucus-covered tentacles around a sea apple's mouth snares floating bits of food, popping each bit into its mouth one at a time. In the process, the tentacles are covered with a fresh coat of sticky mucus, and the whole cycle repeats.

4. THEY’RE ACTIVE AT NIGHT.

Sea apples' waving appendages can look delicious to predatory fish, so the echinoderms minimize the risk of attracting unwanted attention by doing most of their feeding at night. When those tentacles aren’t in use, they’re retracted into the body.

5. THE MOVE ON TUBULAR FEET.

The rows of yellow protuberances running along the sides of this specimen are its feet. They allow sea apples to latch onto rocks and other hard surfaces while feeding. And if one of these feet gets severed, it can grow back.

6. SOME FISH HANG OUT IN SEA APPLES' BUTTS.

Sea apples are poisonous, but a few marine freeloaders capitalize on this very quality. Some small fish have evolved to live inside the invertebrates' digestive tracts, mooching off the sea apples' meals and using their bodies for shelter. In a gross twist of evolution, fish gain entry through the back door, an orifice called the cloaca. In addition expelling waste, the cloaca absorbs fresh oxygen, meaning that sea apples/cucumbers essentially breathe through their anuses.

7. WHEN THREATENED, SEA APPLES CAN EXPAND.

Most full-grown adult sea apples are around 3 to 8 inches long, but they can make themselves look twice as big if they need to escape a threat. By pulling extra water into their bodies, some can grow to the size of a volleyball, according to Advanced Aquarist. After puffing up, they can float on the current and away from danger. Some aquarists might mistake the robust display as a sign of optimum health, but it's usually a reaction to stress.

8. THEY CAN EXPEL THEIR OWN GUTS.

Sea apples use their vibrant appearance to broadcast that they’re packing a dangerous toxin. But to really scare off predators, they puke up some of their own innards. When an attacker gets too close, sea apples can expel various organs through their orifices, and some simultaneously unleash a cloud of the poison holothurin. In an aquarium, the holothurin doesn’t disperse as widely as it would in the sea, and it's been known to wipe out entire fish tanks.

9. SEA APPLES LAY TOXIC EGGS.

These invertebrates reproduce sexually; females release eggs that are later fertilized by clouds of sperm emitted by the males. As many saltwater aquarium keepers know all too well, sea apple eggs are not suitable fish snacks—because they’re poisonous. Scientists have observed that, in Pseudocolochirus violaceus at least, the eggs develop into small, barrel-shaped larvae within two weeks of fertilization.

10. THEY'RE NOT EASILY CONFUSED WITH THIS TREE SPECIES.

Syzgium grande is a coastal tree native to Southeast Asia whose informal name is "sea apple." When fully grown, they can stand more than 140 feet tall. Once a year, it produces attractive clusters of fuzzy white flowers and round green fruits, perhaps prompting its comparison to an apple tree.
