A better understanding of how these amphibians grow new appendages may lead to better wound healing—or even new limbs—in humans. Axolotls are native to Mexico and critically endangered in their ...

Reintroduction of the Cyclin A2 gene enables adult human cardiomyocytes to divide, producing functional daughter cells and promoting heart repair. The therapy uses a replication-deficient adenoviral ...

Every year, millions of lives are suddenly, swiftly transformed by a stroke, which occurs when a blood vessel traveling towards the brain becomes obstructed, causing neurons to die off. Strokes are ...

Feeding the world in the decades ahead is one of humanity's greatest challenges. By 2050, the global population is projected to reach nearly 10 billion people, requiring roughly 70% more calories than ...

After four weeks, there was no difference in the speed of limb regeneration. The study parsed the roles of different elements of this system: one pathway known as alpha-adrenergic signaling is ...

For decades, scientists have studied the remarkable regenerative ability of planarians, triclad flatworms that can basically regrow their entire bodies if necessary. A new study shows that the secret ...

“A reflection and outward view — symbolizing HR’s shift from mirror to window and its path to regaining strategic value.” Global employee engagement sits stubbornly at 21%. That’s the same level ...

Regeneration sounds like a superpower. It is the ability to regrow lost tissues, organs, or limbs. Some creatures, like axolotls or starfish, do this effortlessly. Their bodies replace what was ...

The feathery gilled pink salamanders stop aging early and can regenerate their limbs. Studying them could be the next step in the journey to unlocking effective anti-aging treatments in humans.

Industrial agriculture is profitable, but recent trends show that profit may only last in the short run if soil health isn’t prioritized. Farmers in the central US in the 1930s learned the hard way.

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. Billions of nerve cells send signals coursing through our bodies, serving as conduits ...
