Slow-cycling stem cells in hydra contribute to head regeneration
Biology Open, 2014 Adult stem cells face the challenge of maintaining tissue homeostasis by self-renewal while maintaining their proliferation potential over the lifetime of an organism.

Regeneration and defense: unveiling the molecular interplay in plants
New Phytologist, Volume 246, Issue 6, Page 2484-2494, June 2025.Summary In both plants and animals, tissue or organ regeneration typically follows wounding, which also activates defense responses against pathogenic microbes and herbivores. Both intrinsic and environmental cues guide the molecular decisions between regeneration and defense.

Scientific ReportsThe Notch-signalling pathway plays an important role in pattern formation in Hydra. Using pharmacological Notch inhibitors (DAPT and SAHM1), it has been demonstrated that HvNotch is required for head regeneration and tentacle patterning in Hydra. HvNotch

Longer durability of host–parasite interaction increases host density
Oikos, Volume 2025, Issue 6, June 2025.Comparing cases of parasitism and predation that lead to victim death, parasites need more time to complete victim exploitation. This longer ‘interaction durability' delays energy transfer from host to parasite. During exploitation, parasite virulence differentiates the infected from the susceptible host dynamics.

Biometric and statistical investigations on the cnidoma of the genus Hydra (Cnidaria, Hydrozoa)
Iheringia: Série Zoologia, 2012 This paper deals about the nematocysts like a source of biometric information for comparison between the species Hydra vulgaris Pallas, 1766, Hydra vulgaris pedunculata Deserti et al., 2011 and Hydra pseudoligactis (Hyman, 1931). This biometric tool lets

ChemBioChem, Volume 26, Issue 10, May 27, 2025.The tetrasaccharide linkage region of proteoglycans is synthesized through a series of well‐controlled enzymatic reactions in nature. The expression, activity, and substrate profile of these biosynthetic enzymes and the latest development of chemoenzymatic synthesis of linkage region‐bearing glycopeptides are summarized in this review.

, 2010 We give examples of CAT(0), biautomatic, free-by-cyclic, one-relator groups which have finite-rank free subgroups of huge (Ackermannian) distortion. This leads to elementary examples of groups whose Dehn functions are similarly extravagant. This behaviour originates in manifestations of Hercules-versus-the-hydra battles in string-rewriting.
