Mammal ancestors laid eggs, and this 250-million-year-old fossil finally proves it

In the aftermath of Earth’s most catastrophic extinction event, one unlikely survivor rose to dominate a shattered world: Lystrosaurus. Now,

Scientists just debunked a 50-year myth about Hawaii’s birds

A new study from the University of Hawaiʻi at Mānoa is overturning a decades-old belief that Indigenous Hawaiians hunted native

Scientists finally know where the Colorado River’s missing water is going

For years, water managers have been puzzled as the Colorado River kept delivering less water than expected—even when snowpack levels

This strange “pearling” motion inside cells could change how we understand disease

Mitochondria don’t just generate energy—they also carefully organize their own DNA in a surprisingly elegant way. Scientists have discovered that

The people you live with could be changing your gut bacteria

Spending time with close companions might do more than strengthen bonds—it could also reshape your gut bacteria. In a study

Africa’s forests have flipped from carbon sink to carbon source

Africa’s forests have undergone a shocking reversal, switching from carbon absorbers to carbon emitters after 2010. Researchers found that heavy

Gray whales are entering San Francisco Bay and many aren’t surviving

Gray whales are beginning to break their long-established migration patterns, venturing into risky new territory like San Francisco Bay as

Light makes plants stronger but also holds them back

Light doesn’t just help plants grow—it may also quietly hold them back. Researchers have uncovered a surprising mechanism where light

110,000-year-old discovery rewrites human history: Neanderthals and Homo sapiens worked together

The first-ever published research on Tinshemet Cave reveals that Neanderthals and Homo sapiens in the mid-Middle Paleolithic Levant not only

Life on Mars? Tiny cells just survived shock waves and toxic soil

Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock

Mammal ancestors laid eggs, and this 250-million-year-old fossil finally proves it

In the aftermath of Earth’s most catastrophic extinction event, one unlikely survivor rose to dominate a shattered world: Lystrosaurus. Now, a stunning fossil discovery—an ancient egg containing a curled-up embryo—has finally answered a decades-old mystery about whether mammal ancestors laid

Scientists just debunked a 50-year myth about Hawaii’s birds

A new study from the University of Hawaiʻi at Mānoa is overturning a decades-old belief that Indigenous Hawaiians hunted native waterbirds to extinction. Instead, researchers found no scientific evidence supporting this claim and propose a more complex explanation involving climate

Scientists finally know where the Colorado River’s missing water is going

For years, water managers have been puzzled as the Colorado River kept delivering less water than expected—even when snowpack levels looked promising. New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier springs mean

This strange “pearling” motion inside cells could change how we understand disease

Mitochondria don’t just generate energy—they also carefully organize their own DNA in a surprisingly elegant way. Scientists have discovered that a long-overlooked phenomenon called “mitochondrial pearling,” where mitochondria briefly form bead-like shapes, helps evenly space clusters of mitochondrial DNA.

The people you live with could be changing your gut bacteria

Spending time with close companions might do more than strengthen bonds—it could also reshape your gut bacteria. In a study of island birds, those with stronger social ties shared more gut microbes, especially types that require direct contact to spread.

Africa’s forests have flipped from carbon sink to carbon source

Africa’s forests have undergone a shocking reversal, switching from carbon absorbers to carbon emitters after 2010. Researchers found that heavy deforestation in tropical regions has led to massive biomass losses, far outweighing any gains from regrowth elsewhere. This change could

Gray whales are entering San Francisco Bay and many aren’t surviving

Gray whales are beginning to break their long-established migration patterns, venturing into risky new territory like San Francisco Bay as climate change disrupts their Arctic food supply. But this unexpected detour is proving deadly: nearly one in five whales that

Light makes plants stronger but also holds them back

Light doesn’t just help plants grow—it may also quietly hold them back. Researchers have uncovered a surprising mechanism where light strengthens the “glue” between a plant’s outer skin and its inner tissues. This tighter bond, driven by a compound called

110,000-year-old discovery rewrites human history: Neanderthals and Homo sapiens worked together

The first-ever published research on Tinshemet Cave reveals that Neanderthals and Homo sapiens in the mid-Middle Paleolithic Levant not only coexisted but actively interacted, sharing technology, lifestyles, and burial customs. These interactions fostered cultural exchange, social complexity, and behavioral innovations,

Life on Mars? Tiny cells just survived shock waves and toxic soil

Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts—two major environmental threats on the Red Planet. Their secret weapon was forming protective molecular clusters
