Plant worlds in remote locations
Updated : 2 years, 7 months ago IST
Oceanic islands can be used as models for ecology, biogeography, and evolutionary studies. Many groundbreaking discoveries, including Darwin's theory of evolution, have resulted from the study of island species and their interactions with their living and non-living environments. An internat

Beak shape determines nest material selected by birds: Study
Updated : 2 years, 8 months ago IST
These findings, which were published in Philosophical Transactions of the Royal Society B, include a careful examination of these models, looking into the ecological and evolutionary contexts that underpin these relationships. For example, not all species have equal access to all nest materi

New embryonic cell type that self-destructs to protect developing embryo:
Updated : 2 years, 8 months ago IST
Researchers looking at early human embryo gene activity data have uncovered a previously unknown type of cell that self-destructs days after formation as a quality control measure to safeguard the growing baby. The research provides new information on what occurs in the very early stages of

Fossil evidence indicates that these long-necked reptiles were beheaded by
Updated : 2 years, 8 months ago IST
Compared to modern reptiles, several marine reptiles from the time of the dinosaurs had incredibly lengthy necks. The fact that they had long necks rendered them more vulnerable to predators, even if it was obviously a successful evolutionary strategy, has long been speculated by palaeontolo

CARD8 helps human immune system respond to viruses like Covid 19: Study
Updated : 2 years, 9 months ago IST
Molecular sensors that form the so-called inflammasome help activate inflammatory responses to pathogens. A new study suggested that CARD8 is a highly evolved sensor that can detect a variety of viruses and is critical to the human immune system's capacity to identify and respond to coronavi

Decoding mystery behind structure of birds' wings
Updated : 3 years ago IST
All flight-capable modern birds possess the propatagium, a specialised wing structure that is necessary for flight. This structure's evolutionary ancestry has long been unknown, but recent studies indicate that nonavian dinosaurs may have developed it. The conclusion, which fills certain kno

Disabling single gene in cnidarians causes stinging cell to lose sting
Updated : 3 years ago IST
According to a study, when scientists transformed a single regulatory gene in a sea anemone species, a stinging cell that normally shoots a venomous miniature harpoon for hunting and self-defence switched to shooting a sticky thread that entangles prey.

Do forest trees really "talk" through underground fungi?
Updated : 3 years ago IST
The idea that forest trees can "talk" to each other, share resources with their seedlings -- and even protect them -- through a connective underground web of delicate fungal filaments tickles the imagination.
