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

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

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.

Scientists study 155 new genes to see how humans continue to evolve
Updated : 2 years, 4 months ago IST
Nearly 7 million years ago, modern humans diverged from our chimpanzee ancestors, yet we have since continued to evolve. Within the human lineage, 155 novel genes that spontaneously developed from little fragments of our DNA have been discovered. A handful of these "microgenes" are projected

Study finds how humans continue to evolve with new genes
Updated : 3 years, 2 months ago IST
Even though we diverged from our chimpanzee ancestors about 7 million years ago, we are still evolving today. The human lineage has 155 novel genes that spontaneously developed from little fragments of our DNA. Some of these novel "microgenes" are thought to be linked to diseases that are un

Research finds how intensive agriculture turned wild plant into pervasive
Updated : 3 years, 3 months ago IST
New research in Science is showing how the rise of modern agriculture has turned a North American native plant, the common water hemp, into a problematic agricultural weed.

Plants ability to actively control water loss evolved earlier than priorly
Updated : 4 years, 6 months ago IST
Washington [US], August 26 (ANI): The findings of new research have shed light on when plants first evolved their ability to respond to changing humidity in the air around them. It also found that this was probably a feature of a common ancestor of both ferns and flowering plants.
