Scientists at IIT Mandi have identified the cellular signature of anaesthesia in plants, a discovery that challenges conventional understanding of consciousness. Their research shows plants respond to ...

The cells of animals, plants, and fungi start their lives by being torn apart. Cells are born by division, and just before a parent cell becomes two daughters, it doubles its nuclear DNA and carefully ...

More than 100 million years ago, a flying reptile called a pterosaur flew over the oceans hunting squid and fish.

Researchers from the East China University of Science and Technology have investigated degradation mechanisms in low-silver electrodes used in heterojunction (HJT) solar cells, with the aim of ...

Mitochondria are dynamic organelles that undergo continuous morphological changes, yet exhibit unique, cell-type-specific structures. In rod photoreceptor cells of the retina, these include elongated ...

Before an embryo can use its own genes, it relies on materials that have been packed into the egg. This is a precarious phase. In mammals, the fertilized egg divides several times before activating ...

Damaged DNA can escape from one human cell and infiltrate another. Like prisoners tunneling out of jail, this DNA travels via tubelike structures between neighboring cells, scientists report May 19 in ...
