Frogs seem to “appear” when it rains because wet, cool weather is the best time for them to move, eat, and breed, so they come out of hiding all at once.

How frogs live
Frogs have thin, permeable skin that must stay moist; dry, hot weather can dehydrate or even kill them, so they usually hide in damp soil, under leaves, or near water.

Many species spend the day hidden and are more active at night, so an evening rain makes a lot of frogs visible and noisy at the same time.

Why rain brings them out
Rainy weather is cool, cloudy, and humid, which lets frogs move around without their skin drying out, so they can safely travel farther from ponds and ditches.
Puddles formed by rain give them extra places to sit, hydrate, and “breathe” through their skin, which works best when the skin is moist.

Food becomes easier Rain brings earthworms, snails, slugs, and many insects up to the surface, making hunting much easier for frogs.
Raindrops can knock flying insects down, so frogs can just sit near lights or puddles and grab plentiful prey with less effort.

Breeding and loud croaking
In many species, heavy rain is a signal for breeding season because it fills temporary ponds and ditches where frogs lay eggs safely away from fish.
The loud croaking you hear after rain is usually males calling to attract females to these newly filled water bodies.

“Coming from nowhere” feeling
Outside of rain, frogs hide underground, under stones, in leaf litter, or vegetation near water, so people simply do not notice them.

When a good rain comes, many individuals emerge at once to feed and mate, which makes it look like they suddenly appeared from nowhere.

Fish that build with stones
Male river chub (Nocomis micropogon) gathers small pebbles in its mouth and piles them into a raised mound nest on the stream bed.

Male bluehead chub (a related Nocomis species) can carry thousands of stones, sometimes larger than its own head, to build pyramid‑shaped pebble nests.
These stone nests act like a home for eggs and also shelter eggs of other small minnows that use the same mound.

Why they build these nestsThe pebble mound protects eggs from being washed away by current and from some predators hiding in the sand.

Females choose males partly by the size and quality of the stone nest, so the structure is also a courtship display.

Many other species (called “nest associates”) lay their eggs in these chub nests because survival is higher there than on bare gravel.

Other “builders” you might meanSome cichlid fish move sand and small stones to dig pits or make mounds as breeding sites, but they usually use loose substrate, not big pebble piles like chubs.

The white‑spotted pufferfish makes large circular sand “artworks” and decorates them with shells and small bits of coral, but this is more sand sculpting than stone house building.

Certain cutlip minnows select dark, colored pebbles to decorate mound nests, similar to a bower.

You think time always moves at the same speed?
One second is one second… right?

But your brain knows a deeper truth.
In fear, danger, trauma, or a near-death moment —
time doesn’t slow down… YOUR MIND speeds up.

Your amygdala explodes into survival mode,
your senses sharpen like a camera in hyper-focus,
and your brain starts recording 10x more information per second.

That’s why people say —
“everything felt like slow motion.”
Because inside your brain, it actually did.

Time dilation isn’t just a movie effect.
It’s a real biological superpower.

Triggered by danger…
Activated by trauma…
And sometimes, awakened by deep emotional shock.

Time is real.
But how you experience time?
That is your brain’s decision — not the universe’s.

For years, the skies have been a playground for innovation, pushing the boundaries of what's possible. But this week, one Australian aerospace engineer didn't just push the boundaries; he shattered them, leaving a new world record in his wake. Ben Biggs, a veteran pilot with 15 years of experience, officially claimed the Guinness World Record for the fastest battery-powered remote-controlled quadcopter drone, clocking an astonishing ground speed of 626 km/h (388 mph).

Amid circulating claims linking eggs to cancer risk, the Food Safety and Standards Authority of India has clarified that eggs are safe for consumption and that no scientific evidence supports such allegations. Commissioner, Food and Drug Administration J&K, Smita Sethi told the news agency Kashmir News Trust that the department relies strictly on scientifically verified assessments and the latest FSSAI report clearly states that eggs are safe.

A heartwarming story from northeastern China has captured widespread attention after a father travelled nearly 900 kilometres and changed his entire life so his daughter could enjoy food that reminded her of home. According to a report in South China Morning Post, the daughter, Li Bingdi, is a second-year student at Jilin Normal University in Siping, Jilin province. For almost a year, Li had complained that her university canteen food was unhygienic and lacked the familiar “taste of home”, as reported by Dahe News and cited by SCMP.

The winning Wildlife Photographer of the Year 2025 image was taken with... an eleven-year-old Nikon DSLR
The winners of the Wildlife Photographer of The Year 2025 contest have been unveiled, and once again, it’s a set of incredible images. The overall winner was shot by South African photographer, Wim van den Heever, who takes home the Grand Prize.
His image depicts an otherworldly scene of a rare brown hyena exploring the dilapidated remains of the abandoned mining town of Kolmanskop in Namibia, a setting which creates an almost dystopian atmosphere. Van den Heever explains that he worked for almost ten years to capture his composition of a brown hyena in the perfect location, and his patience paid off, creating a haunting mood that reflects the ability of wildlife to recolonize areas once dominated by human activity.
