A groundbreaking study has discovered a novel way to rejuvenate inactive human senescent cells providing enormous potential for research on ageing and immense scope for improving lifespans
A team led by Professor Lorna Harries at University of Exeter, UK1 has shown...
“CRISPR-Cas systems” in bacteria and viruses identify and destroy invading viral sequences. It is bacterial and archaeal immune system for protection against viral infections. In 2012, CRISPR-Cas system was recognised as a genome editing tool. Since then, wide range of...
Thiomargarita magnifica, the biggest bacteria have evolved to acquire complexity, becoming of eukaryotic cells. This seems to challenge the traditional idea of a prokaryote.
It was in 2009 when scientists had a strange encounter with microbial diversity that exists in...
Some microbes in the deep-sea produce oxygen in a hitherto unknown way. In order to generate energy, the archaea species ‘Nitrosopumilus maritimus’ oxidises ammonia, in presence of oxygen, to nitrate. But when researchers sealed the microbes in airtight containers, without...
Study highlights the key genes which can prevent motor function decline as an organism ages, for now in worms
Ageing is a natural and inevitable process for every organism in which there is a decline in function of many different...
The complete human genome sequence of the two X chromosomes and autosomes from the female tissue derived cell line has been completed. This includes the 8% of the genome sequence that was missing in the original draft that was...
Scientists have developed the first patient-derived stem cell model of albinism. The model will help studying eye conditions related to oculocutaneous albinism (OCA).
Stem cells are unspecialised. They cannot do any specific function in the body but they can divide...
Protein expression refers to the synthesis of proteins within cells using information contained in the DNA or gene.
Proteins are responsible for all the biochemical reactions that take place within the cell. Hence, it makes it necessary to study protein function in...
The traditional grouping of life forms into prokaryotes and eukaryotes was revised in 1977 when rRNA sequence characterisation revealed that archaea (then called 'archaebacteria') are ‘‘as distantly related to bacteria as bacteria are to eukaryotes.‘' This necessitated grouping of living...
Gingko trees lives for thousands years by evolving compensatory mechanisms to maintain a balance between growth and ageing.
Ginkgo biloba, a deciduous gymnosperm tree native to China is known commonly as health supplement and as herbal medicine.
It is also known...
Scientists have revived pigs brain four hours after its death and kept alive outside the body for several hours
Of all organs, brain is most susceptible to continuous supply of blood to meet its immense non- stop requirement of oxygen...
Scientists have replicated the natural process of mammalian embryonic development in the laboratory up to the point of development of brain and heart. Using stem cells, researchers created synthetic mouse embryos outside uterus that recapitulated natural process of development...
Nicotine has a vast array of neurophysiological effects, not all of which are negative despite popular opinion of nicotine as a simplistically harmful substance. Nicotine has various pro-cognitive effects and has even been used in transdermal therapy to improve...
Brown fat is said to be “good". It is known that it plays an important role in thermogenesis and maintains body temperature when exposed to cold conditions. An increase in amount of BAT and/or its activation has been shown...
Study shows gene editing technique to protect one’s descendants from inheritable diseases
A study published in Nature has shown for the first time that a human embryo can be corrected at a very early stage of embryonic development by a gene-editing (also...
A new geometrical shape has been discovered which enables three-dimensional packing of epithelial cells when making curved tissues and organs.
Every living organism begins as a single cell, which then divide into more cells, which further divide and subdivide until...
