In the 2008 film The Dark Knight, there is a scene in which a would-be criminal decides against committing a crime after he sees the Bat Signal in Gotham City’s dark sky. The man chooses to mind his behavior since Batman could see him. But that’s in the fantastical world of comic book movies. That type of thing can’t happen in real life… right? Well, psychologists in Milan, Italy put this to the test.
In a psychological experiment, researchers from the Università Cattolica del Sacro Cuore found the sudden appearance of Batman caused people to become more altruistic. This mass change of behavior among a group has led Francesco Pagnini, Professor of Clinical Psychology at Università Cattolica, and his team to coin this prosocial behavior the “Batman Effect.”
The experiment was fairly simple. Professor Pagnini had a woman who appeared to be pregnant get onto a train with 138 people, including an observer planted to gauge the reactions of the passengers—would any of them offer their seat to her?
The second part of the experiment had the same scenario, but included a man in a Batman costume getting onto the train from another entrance. The purpose of the experiment was to see if an unexpected event, such as the appearance of a superhero, shook up people’s routines and increased awareness of the present moment.
The results of the experiment were surprisingly like a comic book. Without “Batman,” only 37.66% of the passengers offered their seats to the pregnant woman. However, 67.21% of the passengers offered their seats when an unexpected Dark Knight appeared on their subway train. In other words, Batman’s presence caused roughly twice as many people to kindly offer their seats to the pregnant woman compared to a “normal” ride. Another interesting note was that 44% of the people who offered their seats when the Caped Crusader was on the train reported not having seen anyone in a Batman outfit, suggesting that unexpected events could promote prosocial behavior even in the absence of awareness.
“Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality; this may create a context in which individuals become more attuned to social cues,” said Professor Pagnini in a statement. “This suggests a potential mechanism through which novelty and unpredictability promote prosocial behavior, strengthening theories linking attentional shifts to increased social responsiveness.”
Pagnini didn’t rule out that Batman and what he represents played a significant factor in the experiment’s results (aside from the unexpected nature of a superhero taking the subway with regular passengers).
“It is also possible that the superhero figure enhanced the relevance of cultural values, gender roles, and norms of chivalrous help, consistent with research on the ‘priming’ effect associated with superheroes,” added Pagnini. “The figure of Batman could therefore play a prosocial priming role.”
The result of this experiment has had some psychologists offer methods for people who want to be more altruistic or improve their daily lives. It may not be a picture of Batman, but having a photo of someone you admire or aspire to be like can help motivate you towards goals that reflect who they are or what they’ve accomplished. In terms of the subway experiment, that shows that making a slight change in your routine, such as taking a different route to work or a different place to have coffee, would force your brain off of auto-pilot to take in the differences of life around you.
The result of this experiment shows that a little bit of shake-up of your usual routine could increase your awareness of what and who around you could use your help. This could help you become more of a superhero in real life (costume optional).
Since 2015, the Comedy Wildlife Photography Awards, created by photographers and conservationists Paul Joynson-Hicks and Tom Sullam, have been delivering laugh-out-loud moments through the lens of nature. With a mission to entertain while raising awareness about wildlife conservation, the competition celebrates the charming and comical side of the animal kingdom.
Let’s take a joyful stroll down memory lane with some of the most funniest entries from the 2019 contest (and if you’re feeling inspired, you’ll also learn how to submit your own wild and witty shots for future competitions).
OVERALL WINNER, CREATURES OF THE LAND WINNER: “Grab Life By the…”
You don’t think about how hard it would be to be the parent of a small, curious creature with massive, sharp claws. Let’s all take a moment to be grateful that even though it’s very hard to have a human baby, they don’t have super sharp claws. That would make things ten times worse.
CREATURES IN THE AIR WINNER: “Family Disagreement”
I think if I were an otter, I too would constantly clutch my face in disbelief. “I can’t possibly be this cute, can I? Cute nose, fuzzy head, tiny little eyes? That can’t be! Oh, but it is! I really am this adorable! I am! I am!”
Have you seen those videos of foxes diving headfirst into the snow to catch prey? It’s hilarious and fascinating, and I think this fox forgot that there was no snow. His friend is really trying to help him not hurt himself, but his buddy insists on being dumb. Oh, foxes!
“And then Carol was like, ‘You otter come over for dinner sometime!’ Get it? Get it? Man, Carol’s hilarious. So I went over for dinner and she had like, this whole seafood spread. Crabs, clams, mussels…the whole shebang. Anyway, I think I’m going to marry her.”
Just think about how much poise it took for this photographer to take this photo. Not only is the shark sneaking up on this poor fish, but there’s a person behind that camera! Presumably, the photographer escaped unscathed, since he was able to enter this photo in the contest.
It’s clearly not just human women who have to put up with the incessant nagging conversation from dudes we have no interest in talking to. See the look on that bird’s face? Staring straight out just willing him to go away? Tell me you haven’t made that face. Yeah, that’s what I thought.
“O Romeo, Romeo, wherefore art thou, Romeo?” No one really knows this, but squirrels are generally huge Shakespeare fans. They saw him put up a play in Europe centuries ago and have just carried that love for his words through generations and generations of squirrels.
I relate to this bear hard. Anyone who has had to get up and go to work after a long weekend knows this feeling. Sometimes, you just don’t want to deal with anything. Sometimes, you just want to lie on the ground, cover your face with your hands, and nap for a little while longer.
I love this photo so much. Because not only is it a picture of a penguin farting, but it’s a picture of a penguin who is clearly trying to hide the fact that he’s farting and play it off like he’s doing absolutely nothing. He’s just standing there twiddling his wings. He has no idea what that big bubble under his butt is.
There seems to be a whole genre of “Small rodents holding flowers” photos, and I am a sucker for every single one of them. I’m pretty sure this comes up when you look up “cute” in the dictionary. It’s just so pure.
“Hi there! Welcome to my flower. So glad you could make it! It’s a little cold and wet right now, but once the sun comes up we’ll be in business. Help yourself to a dewdrop. They’re especially fresh this morning.”
“And then my friend Steve, the otter, told me that Carol said to him, ‘You otter come over for dinner!’ Get it? Get it? Because they’re otters! So it’s funny. Hey, where’d you go?”
These poor monkeys were just trying to get it on. Their kids were finally out of the tree, they had some peace and quiet, and then they were so rudely interrupted by a photographer. Although mom looks like she was kinda zoning out anyway.
This little chimp is living the life! He’s got it all figured out, and from the looks of him, he’s still a tiny baby. He’s just looking out at the jungle, thinking about all that milk he’s going to drink later.
I bet that when you’re a Snowy Owl and it finally snows, you are just so ecstatically happy. I mean, it’s right there in your name. Look at her face! It’s full of such pure joy.
Like this little monkey, I, too, usually save my existential crises for bath time. There’s something about the weightlessness of floating in the water that makes you question everything you know to be true about yourself and the world.
Who’s calling this snapping turtle slow? He’s just “taking his time.” On another note, I think turtles are probably the most prehistoric-looking creatures that still exist. If you really take the time to look at them, they’re so crazy.
Imagine playing hide and seek on a block of ice as a polar bear. On one hand, there aren’t too many places to hide. On the other hand, you’re looking for white on white, and that’s not easy.
I don’t know if you knew this, but rodents love ABBA. Here is one getting down to “Dancing Queen.” Because they’re so small, they really feel the music down to their bones. Raise your hand if you would watch an all-rodent adaptation of Mamma Mia! Yeah, me too.

A common saying among pet owners is that the hardest thing about loving a dog is saying goodbye. Having a senior dog, especially one raised from a puppy, can be difficult not just because of the inevitable, but also because the pet may be going through age-related ailments or disease before crossing over. It’s a hard thing to experience anyway, but especially when you remember how they were in their prime. Well, veterinary scientists are testing a daily pill that extends a dog’s lifespan while also maintaining their quality of life.
Loyal, a biotech company based in San Francisco, has been trying to develop anti-aging drugs for dogs ever since it was founded. After years of research and testing, they have developed LOY-002, a beef-flavored daily prescription pill for senior dogs aged 10 and older that weigh over 14 pounds. Early testing shows that the pill can add years to a dog’s life, especially larger breeds.
What does this dog lifespan pill do?
The pill interacts and manipulates IGF-1 (Insulin-Like Growth Factor 1), a hormone that’s key to a dog’s cellular growth and metabolism. IGF-1 helps a dog grow in both size and calorie consumption. This hormone helps make young puppies become strong adult dogs. However, it also continues and accelerates aging at a cellular level when a dog is fully grown.
This explains why many larger breeds of dogs tend to live shorter lives than smaller ones. Their IGF-1 levels are higher. It moves them faster towards age-related diseases and discomfort than smaller dogs.
By reducing the excessive IGF-1, LOY-002 reduces the speed of a larger dog’s biological clock. It doesn’t just make them “feel” younger. Slowing everything down adds years to their life and curbs the risk of age-related organ dysfunction, disease, and early death. After thorough testing, LOY-002 cleared two out of the three sections of acceptance before being fully vetted by the Food and Drug Administration.
“Since founding Loyal six years ago, my goal has always been to get the first drug FDA approved for lifespan extension. This safety acceptance brings us very close to achieving that vision,” said Loyal Founder and CEO Celine Halioua. “We are well on our way to bringing the first dog longevity drugs to market.”
How can a senior dog live longer?
Should Loyal receive that final approval, the LOY-002 drug should go to market before the end of 2026. However, veterinarians and dog care experts have some tips on how to help your older dog live longer and healthier.
Visit your dog’s veterinarian often for checkups and keep them notified of any changes in their behavior. They may recommend a specific diet for your dog at their advanced age. Similar to humans, older dogs are encouraged to follow a healthy diet. They should exercise regularly (through walks or playtime) to keep a healthy weight and keep joints strong.
If your dog has joint trouble, your vet may recommend some supplements to help the dog’s mobility and comfort. No matter the issue, it is best to consult with a veterinarian before making lifestyle changes for your dog.
Such advice can help both you and your dog live full lives together. It may also add a few more years of furry companionship along the way, too.

But it wasn’t until the 1960s that methodical research into dolphin communication began. Scientists like John Lilly and the husband-and-wife team of Melba and David Caldwell tried various experiments to decipher the sounds dolphins can make.
The Caldwells figured out a way to record isolated animals in human care. They discovered that each individual dolphin communicated mostly with one unique whistle, which they called the “signature whistle.” Researchers now know that these whistles convey identities much like human names do. Dolphins use them to stay in touch with each other in their murky habitat, where vision is limited. It’s like announcing “I’m over here!” when someone can’t see you.
This collaborative study, led by Randall Wells of Brookfield Zoo Chicago’s Sarasota Dolphin Research Program, involves numerous researchers from a variety of institutions, who study different aspects of dolphin biology, health, ecology and behavior. Begun in 1970, this is the longest-running research project on a population of wild cetaceans – whales, dolphins and porpoises – in the world.

Experienced researchers can sometimes identify them by sight in the field, and they photograph them to confirm their identity in the lab.
Recording and observing
Researchers know the age, sex and maternal relatedness of almost all of the approximately 170 dolphins in the Sarasota community. This depth of knowledge provides an unprecedented opportunity to study communication in a wild cetacean species.
The dolphins in the Sarasota project are periodically subject to brief catch-and-release health assessments, during which researchers, including me, briefly handle individual dolphins.
Our team attaches suction-cup hydrophones directly onto each dolphin’s melon – that is, its forehead. We then record the dolphins continuously throughout the health assessments, taking notes on who is being recorded when, and what is happening at the time.
This is how my colleagues and I were able to confirm that wild dolphins, like captive animals, produced large numbers of individually distinctive signature whistles when briefly isolated from other dolphins. Through observations and recordings of known free-swimming dolphins, we were further able to confirm that they produced these same signature whistles in undisturbed contexts.
We have organized these recordings into the Sarasota Dolphin Whistle Database, which now contains nearly 1,000 recording sessions of 324 individual dolphins. More than half of the dolphins in the database have been recorded more than once.
We identify each dolphin’s signature whistle based on its prevalence: In the catch-and-release context, about 85% of the whistles that dolphins produced are signature whistles. We can identify these visually, by viewing plots of frequency vs. time called spectrograms.

Signature whistles and ‘motherese’
The Sarasota Dolphin Whistle Database has proved to be a rich resource for understanding dolphin communication. For instance, we have discovered that some calves develop signature whistles similar to those of their mothers, but many do not, raising questions about what factors influence signature whistle development.
Dolphin mothers modify their signature whistles when communicating with their calves by increasing the maximum frequency, or pitch. This is similar to human caregivers using a higher-pitched voice when communicating with young children – a phenomenon known as “motherese.”
Also similar to humans is how dolphins will initiate contact with another dolphin by imitating their signature whistle – what we call a signature whistle copy. This is similar to how you would use someone’s name to call out to them.
Our team is interested in finding out if dolphins also copy whistles of others who aren’t present, potentially talking about them. We have seen evidence of this in our recordings of dolphins during health assessments, which provide a rare context to document this phenomenon convincingly. But we still have more work to do to confirm that these are more than chance similarities in whistles.
Shared whistle types
Another exciting development has been our recent discovery of shared whistle types — ones that are used by multiple animals and that are not signature whistles. We call these non-signature whistles.
I could hardly believe my ears when I first discovered a repeated, shared non-signature whistle type being produced by multiple dolphins in response to sounds we play back to them through an underwater speaker. We had previously believed that these non-signature whistles were somewhat random, but now I was hearing many different dolphins making a similar whistle type.
Our team originally had been using the playbacks to try to determine whether dolphins use “voice cues” to recognize each other – similar to how you can recognize the voice of someone you know. Although we found that dolphins did not use voice cues, our discovery of shared non-signature whistle types has led to an entirely new research direction.

So far, I’ve identified at least 20 different shared non-signature whistle types, and I am continuing to build our catalog. We are hoping that artificial intelligence methods may help us categorize these whistle types in the future.
To understand how these shared non-signature whistle types function, we are carrying out more playback experiments, filming the dolphins’ responses with drones. We’ve found that one such whistle often leads the dolphins to swim away, suggesting a possible alarm-type function. We have also found that another type might be an expression of surprise, as we have seen animals produce it when they hear unexpected stimuli.
More difficult, more interesting
So far, the main takeaway from our experiments has been that dolphin communication is complex and that there are not going to be one-size-fits-all responses to any non-signature whistle type. This isn’t surprising, given that, like us, these animals have complicated social relationships that could affect how they respond to different sound types.
For instance, when you hear someone call your name, you may respond differently if you are with a group of people or alone, or if you recently had an argument with someone, or if you’re hungry and on your way to eat.
Our team has a lot more work ahead to sample as many dolphins in as many contexts as possible, such as different ages, sexes, group compositions and activities.
This makes my job more difficult – and far more interesting. I feel lucky every day I am able to spend working on the seemingly infinite number of fascinating research questions about dolphin communication that await answers.
