When we think of death, we imagine a final, irreversible end. But what if death is not as absolute as it seems? What if some ...

Feedback, a Lego fan, delves into a new science-related set, and learns that the model of a DNA double helix is the wrong way ...

They have rewritten the genetic code of an organism, opening up unprecedented possibilities ... The scientists compressed redundant codons into a single one, thereby freeing up codons for new ...

But scientists have found that a more complex organism — a single-celled alga with a nucleus — can do it, too, thanks to a newly identified piece of cellular architecture. They're calling it ...

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 ...

Fueled by the mixing and matching of genes from two evolutionarily distinct cells, endosymbiosis led to the formation of a single new organism with emergent and transformative biochemical properties.

The central nervous system produces electrical impulses for rapid response. New organisms are produced when male and female haploid gametes fuse. In mammals, gametes are produced in the testes or ...

A whole new organism with skin, eyes, heart, liver and all of the organs it needs, will develop from the embryonic stem cells. This allows the organism to have all the tissues it needs with the ...

Meiosis, on the other hand, only occurs in eukaryotic organisms that reproduce sexually. During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes.

But the move from engineering organisms in which mere fractions of genomes have been manipulated to the point where significant portions have been designed by humans poses several new ethical ...

leading to new insights that inform development of additional tools and resources. This self-perpetuating cycle is common among model organisms—researchers use them because it has become easy ...
