Regeneration is one of the great mysteries of biology. Planarians are flatworms capable of
dramatic feats of regeneration, which have been studied for over 2 centuries. Recent …

Most research on mechanisms of aging is being conducted in a very limited number of
classical model species, ie, laboratory mouse (Mus musculus), rat (Rattus norvegicus …

Proper biological interpretation of a phylogeny can sometimes hinge on the placement of
key taxa—or fail when such key taxa are not sampled. In this light, we here present the first …

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Bats possess extraordinary adaptations, including flight, echolocation, extreme longevity
and unique immunity. High-quality genomes are crucial for understanding the molecular …

Third-generation sequencing technologies provided by Pacific Biosciences and Oxford
Nanopore Technologies generate read lengths in the scale of kilobasepairs. However, these …

Toll-like receptors (TLRs) are transmembrane pattern recognition receptors that are best
known for their roles in innate immunity for the detection of and defense against microbial …

Planarians are a group of flatworms. Some planarian species have remarkable regenerative
abilities, which involve abundant pluripotent adult stem cells. This makes these worms a …

RNA viruses are the only known RNA-protein (RNP) entities capable of autonomous
replication (albeit within a permissive host environment). A 33.5 kilobase (kb) nidovirus has …

Flatworms (Platyhelminthes) are a basally branching phylum that harbours a wealth of
fascinating biology, including planarians with their astonishing regenerative abilities and the …
