Teeny, single-cell creatures floating in the ocean may be the first organisms ever confirmed to eat viruses. Scientists scooped up the organisms, known as protists, from the surface waters of the Gulf ...

The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by ...

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical ...

Metacaspases, ancestral homologues of the caspase family, are pivotal cysteine proteases found in a wide range of unicellular organisms, including yeasts, algae, and phytoplankton. These enzymes ...

The ability of cells to self-destruct appears to be essential for cellular life. However, the existence of genetically programmed death pathways in single-cell organisms has been long debated. Thus, ...

Ribosomes, the protein factories of the cell, are essential for all living organisms. They bind to mRNA and move along the ...

Cancer research, drug safety testing and aging biology may all gain a major boost from a new fluorescent sensor developed at ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing ...

Consider the cosmos: There are around 100 billion galaxies in the vast universe, all teeming with stars, planets, and dust. The myriad galaxies are connected together through a giant cosmic web made ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in ...

Large swaths of single-celled eukaryotes, non-bacterial single-cell organisms like microalgae, fungi or mold, can control microbiomes (a collection of tiny microbes, mostly bacteria) by secreting ...

A breakthrough live-cell sensor makes DNA repair visible as it happens, unlocking new possibilities in biology and medicine.
