What we can learn from how penguins express affection

Pebbling, a term used to describe small acts of love within a relationship, comes from penguins. Male gentoo penguins, a species of penguin that lives on sub-Antarctic islands, present pebbles to their potential mates later used to build nests. This small but helpful act is something we humans can learn from. Think of the “pebbles” you can share with loved ones on a daily basis.

How women grow tiny humans inside of them

Pregnancy is a complex biological journey, lasting about 40 weeks. When a sperm fertilizes an egg, that event triggers intricate cellular and hormonal processes, driven by hardwired cellular instructions, which lead to cell division, differentiation, and development—ultimately culminating in the birth of a baby.

Korea's "real-life mermaids"

A look at how fish less than two inches long climb up 50-foot waterfalls

Shellears use tiny hooks on their front pectoral fins to grip rock like Velcro and take many pauses to recover energy between bursts of movement. Their pectoral girdle—an arch of bone—supports the muscle system needed for the roughly ten-hour climb.

Coral polyps reproduce via broadcast spawning, where entire reefs simultaneously release reproductive cells for about one hour, once a year.

When caught in the mouths of cardinal fish, seed shrimp release glowing, bioluminescent chemicals, which alert predators of the cardinal fish, prompting the shrimp's ejection.

What a tiny marine worm can tell us about our brains

Meet the amphioxus, a small eel-like animal that has a lot to teach us about brain evolution. The genetic roots of our brains can be seen in these unusual creatures. This three-minute educational video focuses on the evolutionary history of the human brain through these odd little critters with a 500-million-year-old history.

Dolphins have doulas too?

For the first time in over a decade, a dolphin gave birth at Brookfield Zoo, and she didn’t do it alone. Right beside her was another dolphin, acting as a doula. Why do dolphins support each other this way? The answer reveals something incredible about how animals care for one another.

Inside the pigeon race with $50K at stake

More than 1,000 pigeons are released each year at the American Racing Pigeon Union convention as owners wait to see which of the birds arrives home first. This essay unwraps the niche activity's paradoxical love for the birds despite its at times utilitarian treatment of them.

The purpose of narwhal tusks has mystified researchers for centuries

Nicknamed the "unicorn of the sea," narwhals have no teeth aside from two canines that grow directly forward as tusks. For roughly 85% of females, they stay embedded in the bone. For males, they grow into large, spirally tusks that are full of nerve endings and blood vessels. Scientists today believe that tusks likely formed for sexual selection purposes and eventually evolved to assist in other processes, such as hunting.

How Seabiscuit's DNA made him a winner

Seabiscuit's sudden success in the sport has been framed as a classic against-the-odds sports story. One Binghamton University molecular physiologist wanted to go a bit deeper, though, to see how much genetics played a role in the horse's legendary career. Using the horse's silvered hooves, his research team discovered that Seabiscuit's genotype was typically associated with late bloomers, a finding confirmed by the horse's track record.

The hippocampus, a structure in the brain, plays a crucial role in memory formation

The seahorse-shaped structure transfers short-term memories to long-term storage during sleep. It is located in the temporal lobes, above each ear, and aids in spatial navigation and remembering directions.

The Devil's Hole pupfish can be found in only one place in the world

The critically endangered fish species can be found in only one cave in the middle of the Mojave Desert called Devil's Hole. In 2016, three men broke into the protected area to purposefully harm the fish.

Sailor tattoos represent naval milestones

Sailors often come home with mermaids or turtles adorning their bodies. But what does it mean to have permanent images of propellers on your bum, British galleons with soaring tiers of sails on your chest, or a bicep portrait of the Roman god Neptune? Those tattoos represent meaningful naval milestones.

Two marsupials thought to be extinct discovered in New Guinea

The pygmy long-fingered possum and the newly described ring-tailed glider were discovered in 2026 after scientists believed the species had been extinct for 6,000 years. The pygmy long-fingered possum is partially defined by its unusual trait of one finger on each hand that is twice as long as the others.

How the heart achieves its first beat

Scientists observed zebrafish embryos as they grew and isolated the several-second-long initial heartbeats to better understand this crucial moment in every heart's life. The zebrafish's heart starts beating 20 hours into their existence. Each heart cell activates electrically at random, without rhythm. As these cells mature, they become more sensitive to electrical charges; as they all fire, a rhythm is established and a pulse is born.

SpongeBob exemplifies Aristotle's philosophy for living well

In today's society, SpongeBob's life as a single man, line cook, and town fool may not seem appealing. But SpongeBob is perhaps the happiest creature in Bikini Bottom, because he understands that happiness doesn't come from external factors like money, recognition, or power.

The myths around London's tiniest sculpture

The Philpot Lane mice have been considered London's smallest sculpture for decades, delighting visitors and locals alike. But there's a common story told for why the unusual sculpture—which features two mice fighting for a piece of cheese—was placed there, saying it commemorated the death of a construction worker fighting over a lunch in the 1800s. The author of this article argues the evidence for such a story is lacking. Dive into the obscure history here.

Why physiology and genetics prevent king bees from existing

The mating process is fatal to male honey bees, as their endophallus detaches from their bodies and remains temporarily within the queen. Because fertilized honey bee eggs develop into female bees, if a male somehow did survive and become king, his line of succession would also abruptly end.

Corals are themselves not coral reefs—the term refers to the tiny marine invertebrates that build the rigid reef.

She sells seashells by the seashore or, more accurately, she sells dinosaur fossils along the Jurassic Coast

Now known as the mother of paleontology, Mary Anning was 12 years old in 1811 when her seashore scrounging uncovered an ichthyosaur fossil, the first complete one known to the London scientific community at the time. She spent the rest of her life contributing to a field that didn’t care to welcome her. This article details her life and work.
