Baby sperm whale filmed feeding for first time, solving long-time scientific mystery

How the elusive mammals nurse with that bulbous head has been a curiosity for decades.

Sperm whale heads don't seem like they'd be conducive to nursing.

We know that mammals feed their young with milk from their own bodies, and we know that whales are mammals. But the logistics of how some whales make suckling happen has been a bit of a mystery for scientists. Such has been the case with sperm whales.

Sperm whales are uniquely shaped, with humongous, block-shaped heads that house the largest brains in the animal world. Like other cetaceans, sperm whale babies rely on their mother's milk for sustenance in their first year or two. And also like other cetaceans, a sperm whale mama's nipple is inverted—it doesn't stick out from her body like many mammals, but rather is hidden inside a mammary slit.

Most whale and dolphin babies nudge the mammary slit to expose the nipple, allowing them to "suckle." A sperm whale baby's head and mouth aren't really designed for suckling in the traditional sense, obviously, as its massive nose protrudes over its much smaller lower jaw. But even in the whale sense of mom shooting milk into a baby's mouth, it's been unclear how it works for sperm whales due to their oddly shaped heads. Photos and observations have led researchers to believe that the mother whale expresses milk into the water for the baby to ingests outside of her body, but the real mechanics haven't been clearly understood.

With the proliferation of underwater photography and filmography, it may seem strange that we don't have more nursing whale evidence to examine, but because baby whales can't breathe and nurse at the same time, nursing events are usually quite short. Even being in the right place at the right time to observe a whale nursing is rare, much less capturing it on film.

A four-part documentary series from National Geographic released in 2021 has provided, for the first time, film footage of a sperm whale baby nursing. It shows how the baby actually inserting its lower jaw into the mother's mammary slit, and the milk—which contains ten times more fat than human milk and is the consistency of yogurt—shooting directly into the baby whale's mouth.

The documentary series containing this footage, "Secrets of the Whales," was conceived of by National Geographic Explorer and photographer Brian Skerry and follows the stories of five different whale species—narwhals, humpbacks, belugas, sperm whales, and orcas. It was filmed in 24 locations around the world and took three years to make. Produced by award-winning filmmaker and conservationist James Cameron (of "Titanic" and "Avatar" fame) and narrated by award-winning actress and conservationist Sigourney Weaver, the series is sure to please whale lovers and nature lovers alike.

In addition to sperm whale babies breastfeeding, the docuseries shows how beluga whales name themselves so groups can keep track of each other, how baby belugas share their moms' call signs, how 30,000 humpbacks travel together from Australia to Antarctica and use breeches to talk to each other, and how a beluga pod adopted a narwhal into their bod—apparently the first ever cross-species adoption ever recorded.

Executive Producer James Cameron called the series a "challenging, daunting project" in a SXSW Conference panel. "It's also so important for people to understand and for this film to illuminate how these creatures think, how they feel, what their emotion is like, what their society is like," he said, "because we won't protect what we don't love."

The filmmakers hope that by sharing with people the unique identities of the whales they followed, they can inspire people to think about how these magnificent mammals can be better protected.

"It's inescapable that they're being poisoned by us, that they're being deafened by us, or their behaviors, all of their feeding strategies and mating strategies and reproductive strategies are being dismantled by all of this noise from shipping channels and military sonars and all that," Cameron said. "They're going to continue to decline. The right whales are down to about 300…We barely understand these animals, so I think we have to, as a society, we have to think about doing it better."

Indeed we do.

Happiness researcher explains how making a 'reverse bucket list' can change your life

Counterintuitive in our culture, but effective.

Harvard researcher Arthur C. Brooks studies what leads to human happiness.

We live in a society that prizes ambition, celebrating goal-setting, and hustle culture as praiseworthy vehicles on the road to success. We also live in a society that associates successfully getting whatever our hearts desire with happiness. The formula we internalize from an early age is that desire + ambition + goal-setting + doing what it takes = a successful, happy life.

But as Harvard University happiness researcher Arthur C. Brooks has found, in his studies as well as his own experience, that happiness doesn't follow that formula. "It took me too long to figure this one out," Brooks told podcast host Tim Ferris, explaining why he uses a "reverse bucket list" to live a happier life.

bucket list, wants, desires, goals, detachment Many people make bucket lists of things they want in life. Giphy

Brooks shared that on his birthday, he would always make a list of his desires, ambitions, and things he wanted to accomplish—a bucket list. But when he was 50, he found his bucket list from when he was 40 and had an epiphany: "I looked at that list from when I was 40, and I'd checked everything off that list. And I was less happy at 50 than I was at 40."

As a social scientist, he recognized that he was doing something wrong and analyzed it.

"This is a neurophysiological problem and a psychological problem all rolled into one handy package," he said. "I was making the mistake of thinking that my satisfaction would come from having more. And the truth of the matter is that lasting and stable satisfaction, which doesn't wear off in a minute, comes when you understand that your satisfaction is your haves divided by your wants…You can increase your satisfaction temporarily and inefficiently by having more, or permanently and securely by wanting less."

Brooks concluded that he needed a "reverse bucket list" that would help him "consciously detach" from his worldly wants and desires by simply writing them down and crossing them off.

"I know that these things are going to occur to me as natural goals," Brooks said, citing human evolutionary psychology. "But I do not want to be owned by them. I want to manage them." He discussed moving those desires from the instinctual limbic system to the conscious pre-frontal cortex by examining each one and saying, "Maybe I get it, maybe I don't," but crossing them off as attachments. "And I'm free…it works," he said.

- YouTube www.youtube.com

"When I write them down, I acknowledge that I have the desire," he explained on X. "When I cross them out, I acknowledge that I will not be attached to this goal."

The idea that attachment itself causes unhappiness is a concept found in many spiritual traditions, but it is most closely associated with Buddhism. Mike Brooks, PhD, explains that humans need healthy attachments, such as an attachment to staying alive and attachments to loved ones, to avoid suffering. But many things to which we are attached are not necessarily healthy, either by degree (over-attachment) or by nature (being attached to things that are impermanent).

"We should strive for flexibility in our attachments because the objects of our attachment are inherently in flux," Brooks writes in Psychology Today. "In this way, we suffer unnecessarily when we don't accept their impermanent nature."

What Arthur C. Brooks suggests that we strive to detach ourselves from our wants and desires because the simplest way to solve the 'haves/wants = happiness' formula is to reduce the denominator. The reverse bucket list, in which you cross off desires before you fulfill them, can help free you from attachment and lead to a happier overall existence.

40 years after the Challenger exploded, one teacher shares how the ride was almost her fate

"I had no idea that anything like this could ever be part of my life."

The Challenger crew.

In January 1986, the space shuttle Challenger took off with seven crew members on board, ready to make history. It was a big deal because this space mission wasn't just full of astronauts. Christa McAuliffe, a high school history teacher, was on board the spacecraft after winning a contest for the Teacher in Space Project. This would've made her the first teacher in space, so schools across the country wheeled televisions into their classrooms to allow students to watch history.

Instead, tragedy struck. The shuttle exploded just 73 seconds after takeoff due to "the destruction of the seals that are intended to prevent hot gases from leaking through the joint during the propellant burn of the rocket motor," according to NASA. All seven passengers on the Challenger perished in the explosion, leaving the country in shock.

January 2026 was the 40th anniversary of the accident, and NewsChannel 5 caught up with one of the teachers who was competing for the seat McAuliffe occupied. Carolyn Dobbins taught at McMurray Middle in Tennessee in 1984 when NASA announced the Teacher in Space Project. Having always wanted to go to space, Dobbins applied for a seat on the shuttle. Over 11,000 teachers applied to be the one who would make history, and to Dobbins' surprise, she was chosen as a semifinalist. "I had no idea that anything like this could ever be part of my life," she said.

The retired teacher explains to the news station that she spent days on her application for space, saying, "An amazing thing happened." She shares about the series of snow days in 1985. "Snow day. Then we had another snow day and another snow day. Those snow days were what I needed! It was basically a mini-book about your beliefs, your desire to go into space, getting to the soul of the person."

She admits that some of her students were worried about her going into space if she were to be chosen, but she brushed off their concerns, saying, "'Oh, I'll be back.'" Dobbins was completely confident in the success of the mission and excited to be able to do something she once thought was impossible. After being interviewed by a panel in Washington, D.C., she was sure she would be chosen for the mission. All of the teachers invited to be interviewed were also confident they'd be chosen, according to Dobbins. But only one could go, and the person chosen was 37-year-old mom of two, Christa McAuliffe, a teacher at Concord High School in Concord, New Hampshire.

Dobbins stood in front of her television watching the shuttle take off instead of experiencing it herself. Once the announcer said the magic words, "We have liftoff," the almost astronaut shares that she let out a sigh of relief before saying, "Way to go, Christa." She then turned off the television.

"Within seconds, the phone rang," Dobbins tells NewsChannel 5. "It was a friend. I said, 'Isn't it great? The shuttle has gone!' She said, 'Carolyn, you don't know.' It was the tone. You don't know. I just put the phone down, flipped on the TV. There it was. Already the footage was going of the explosion. That is still such an emotional moment."

Dobbins taught for 53 years before retiring, and while she would've been willing to go on another mission that aimed to put a teacher in space, she's thankful for the life she has been able to live.

27 English words people have a hard time enunciating properly, even native speakers

"The word I notice people struggle with is 'vulnerable'. Something about that N following an L is tricky."

English words that are difficult to enunciate.

The English language is hard to master, even for native speakers. With over an estimated one million words in the language, not only are English words hard to memorize—they can be hard to properly pronounce and enunciate. Getting tripped up with pronunciation can make your communication unclear, or worse—make you sound uneducated.

As American English teacher Vanessa explains, many mispronounced words are common and used in daily conversation due to tricky consonants and vowels in English words. But by knowing the proper pronunciation, it can help you become a more confident speaker, which is why she shared 33 words that are hard for English language learners to pronounce, such as "probably," "drawer," and "sixth."

On the subreddit r/words, a person posed the question: "What's a word you've noticed many native English speakers have difficulty enunciating even though the word is used fairly often?"

Turns out, there are a menagerie of words people notoriously stumble over. These are 27 English words that people say are the hardest to enunciate.

How to keep your mouth shut in conversations when you know you should really stay quiet

Most people never regret just staying silent.

A woman with her finger over her mouth.

It can be hard to stay quiet when you feel like you just have to speak your mind. But sometimes it's not a great idea to share your opinions on current events with your dad or tell your boss where they're wrong in a meeting. And having a bit of self-control during a fight with your spouse is a good way to avoid apologizing the next morning.

Further, when we fight the urge to talk when it's not necessary, we become better listeners and give others a moment in the spotlight to share their views. Building that small mental muscle to respond to events rather than react can make all the difference in social situations.

What is the WAIT method?

One way people have honed the skill of holding back when they feel the burning urge to speak up is the WAIT method, an acronym for the question you should ask yourself in that moment: "Why Am I Talking?" Pausing to consider the question before you open your mouth can shift your focus from "being heard" to "adding value" to any conversation.

The Center for The Empowerment Dynamic has some questions we should consider after taking a WAIT moment:

What is my intention behind what I am about to say?
What question can I ask to better understand what the other person is saying?
Is my need to talk an attempt to divert the attention to me?
How might I become comfortable with silence rather than succumb to my urge to talk?

The WAIT method is a good way to avoid talking too much. In work meetings, people who overtalk risk losing everyone's attention and diluting their point to the extent that others aren't quite sure what they were trying to say. Even worse, they can come across as attention hogs or know-it-alls. Often, the people who get to the heart of the matter succinctly are the ones who are noticed and respected.

Just because you're commanding the attention of the room doesn't mean you're doing yourself any favors or helping other people in the conversation.

The WAIT method is also a great way to give yourself a breather and let things sit for a moment during a heated, emotional discussion. It gives you a chance to cool down and rethink your goals for the conversation. It can also help you avoid saying something you regret.

How much should I talk in a meeting?

So if it's a work situation, like a team meeting, you don't want to be completely silent. How often should you speak up?

Cary Pfeffer, a speaking coach and media trainer, shared an example of the appropriate amount of time to talk in a meeting with six people:

"I would suggest a good measure would be three contributions over an hour-long meeting from each non-leader participant. If anyone is talking five/six/seven times you are over-participating! Allow someone else to weigh in, even if that means an occasional awkward silence. Anything less seems like your voice is just not being represented, and anything over three contributions is too much."

Ultimately, the WAIT method is about taking a second to make sure you're not just talking to hear yourself speak. It helps ensure that you have a clear goal for participating in the conversation and that you're adding value for others. Knowing when and why to say something is the best way to make a positive contribution and avoid shooting yourself in the foot.

Video games used to build the cognitive skills Gen Alpha is missing out on. It's an easy fix.

"Children in the '90s played games that forced the brain to fail and try again."

Kids playing video games.

There was nothing more frustrating as a kid in the '90s than almost completing a level in a game only to hear that dreaded sound. It was your last life blinking before your eyes. Your only choice was to start over or turn off the video game and try again tomorrow. There was no getting around the fact that you were going to have to do it all over again, but next time you'd be faster, smarter, and better prepared than the last.

This is a skill that was built through repetition for Millennials and Gen X. That small annoyance in older video games exercised a muscle that would be helpful throughout life—one that increased the cognitive skills of these two older generations. And while older Gen Zers experienced this important brain development tool built into older video games, younger Gen Zers and Gen Alpha are critically missing out.

The brain development skills consistently present in video games from the late '70s through the '90s were frustration tolerance, critical thinking skills, delayed gratification, and pattern recognition. Licensed mental health counselor and former teacher, Veronica Lichtenstein, discussed '90s video games with Newsweek, saying, "You fought through levels, memorized patterns and finally saw the ending. It felt like you accomplished something. Your brain gave you this solid, lasting dose of satisfaction, like finishing a tough project.”

In a video by The Pizza Breakroom on Instagram, two men discuss an article allegedly written by a psychologist exploring this very phenomenon. "He said children in the '90s played games that forced the brain to fail and try again," one man reads. "Mario, Sonic, Prince of Persia, you had three lives, no saves, no hints. When you lost you learned patience, planning, and frustration tolerance. Today, many games guide kids step-by-step. Autosave every ten seconds and removes real challenge."

A post shared by Pizza In The Breakroom (@pizzainthebreakroom)

Games like Roblox and Minecraft, which a lot of kids enjoy playing, are never-ending. The game seems to be designed to encourage the player to spend money to keep up with trends, such as offering new "skins." This isn't game money; it's actual money that requires an adult's debit or credit card. There are no significant rewards offered through the satisfaction of beating a level or the game in its entirety. If a child is struggling in the room they chose to play in, the game allows them to leave and enter a different room filled with different players.

“Nineties games are a challenge for building your skills. Today’s games are often a test for your psychological resistance. A great deal are built to track, exploit and addict,” Lichtenstein shares with Newsweek.

But all hope is not lost on building these important skills in the youngest generations. Nineties games are still around, along with their original, refurbished consoles. There are also all-in-one Nintendo and Sega consoles that have all the '90s games preloaded. Parents can encourage video game play on actual consoles, not tablets or computers. A big perk is also that parents can actually get to play with their child while jogging their own memory of cheat codes and game layout.

For some, it may be difficult to watch their child struggle to figure out how to move through the old school games, but the point is for them to learn frustration tolerance and other cognitive skills. These skills are essential to navigate the world as an adult, and introducing kids to the games their parents played at their age is a fun way to do it.
