Lego blocks for precise gene editing

DNA is the core-element of life as we know it. It can be imagined as a long helical double strand composed of sequences of information written with four chemical "letters" called nucleotides. Determinate sequences of letters delineate stretches of DNA called genes, which in turn... click to read more

Human gut parasite has a sinister use for its stolen genes

It is well established knowledge that bacteria routinely exchange genes between unrelated species, creating an extensive network of information flow independent of sexual reproduction. By acquiring new genes, each being a blueprint for a single protein, the bacteria gain also the functions the proteins perform... click to read more

What happens to our genes in the twilight of death?

Death -- the ultimate end of everyone's journey. What is there to study? Is anything interesting happening? Aside from religious and philosophical discourses, valuable knowledge might be obtained from tangible physical facts. Consider an analogy: a disaster happens in a chemical plant that results in... click to read more

Amoebas trap bacteria using nets of DNA: the same mechanism as human immune cells

Our multicellular bodies containing trillions of cells seem to have little in common with protists, the tiny single-celled creatures inhabiting every drop of water, which spend their days eating bacteria or each other, parasitizing larger organisms or living from light. And yet, this is how... click to read more

A new code for a new life

Life on our planet is based on DNA. DNA is a big molecule present in all organisms, and it contains the instructions to build each of life's components. It is the biological way to store and spread information. It is the universal language of life... click to read more
