Coronaviruses are not new; these are as old as anything in the world and are known to cause common cold among humans for ages. However, its latest variant, the ‘SARS-CoV-2’ currently in news for causing COVID-19 pandemic is new.   Often,...
Deletion of Phf21b gene is known to be associated with cancer and depression. New research now indicates that timely expression of this gene plays a key role in neural stem cell differentiation and brain development  A latest research published in...
Case study reports first rare semi-identical twins in humans to be identified during pregnancy and only second ever known till now Identical twins (monozygotic) are conceived when cells from a single egg are fertilized by a single sperm and they...
A new study reveals that bacterial DNA can be read either forwards or backwards due to the presence of symmetry in their DNA signals1. This finding challenges the existing knowledge about gene transcription, the mechanism by which the genes...
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...
Androgens such as testosterone are generally viewed simplistically as creating aggression, impulsivity and antisocial behaviours. However, androgens influence behaviour in a complex way which includes promoting both pro- and antisocial behaviours, with a behavioural trend to increase social status1....
The ambitious mission of replicating the human brain onto a computer and achieving immortality. Multiple research shows that we could well imagine a future where infinite number of humans can upload their minds to the computer thus having an actual...
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...
The double-helix structure of DNA was first discovered and reported in the journal Nature in April 1953 by Rosalind Franklin (1). However, she did not get the Nobel prize for the discovery of double helix structure of DNA. The...
A recent 12 week trial comparing a normal carbohydrate-containing diet to the ketogenic diet in Alzheimer's Disease patients discovered that those who underwent a ketogenic diet increased their quality of life and activities of daily living outcomes, whilst also...
‘Several questions about origin of life have been answered, but much remains to be studied’’ said Stanley Miller and Harold Urey way back in 1959 after reporting laboratory synthesis of amino acids in primitive earth conditions. Many advances down...
First study to show development of interspecies chimera as a new source of organs for transplants In a study published in Cell1, chimeras - named after the mythical lion-goat-serpent monster – are made for the first time by combining material from...
A first study has shown how an animal society actively reorganizes itself to reduce the spread of disease. Generally speaking, high population density in a geographical region is the biggest factor which contributes to faster spread of a disease. When...
‘’The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information from DNA to protein via RNA. It states that such information is unidirectional from DNA to protein and cannot be transferred from protein to...
Adult frogs have been shown for the first time to regrow amputated legs marking it as a breakthrough for organ regeneration. Regeneration means re-growing a damaged or missing part of an organ from residual tissue. Adult humans can successfully regenerate...
New study shows that it might be possible to transfer memory between organisms by transferring RNA from a trained organism into an untrained one RNA or ribonucleic acid is the cellular ‘messenger’ which codes for proteins and carries DNA’s instructions...
Human Proteome Project (HPP) was launched in 2010 after successful completion of Human Genome Project (HGP) to identify, characterise and map human proteome (the entire set of proteins expressed by the human genome). On its tenth anniversary, HPP has...
Scientists have demonstrated for the first time a multiple-person ‘brain-to-brain’ interface where three persons collaborated to complete a task via direct ‘brain-to-brain’ communication. This interface called BrainNet paves way for direct collaboration between brains for solving a problem. A brain-to-brain interface in...
The Human Genome Project revealed that ~1-2% of our genome makes functional proteins while the role of the remaining 98-99% remains enigmatic. Researchers have tried to uncover the mysteries surrounding the same and this article throws light on our...
For the first time dormant multicellular organisms’ nematodes were revived after being buried in permafrost deposits for thousands of years. In quite an interesting discovery made by a team of Russian researchers, ancient roundworms (also called nematodes) which had solidified...
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...
This first case of genetic manipulation in a lizard has created a model organism that could help gain further understanding of reptile evolution and development CRISPR-Cas9 or simply CRISPR is a unique, fast and inexpensive gene editing tool which enables...
Anorexia nervosa is an extreme eating disorder characterized with significant weight loss. Study on genetic origins of anorexia nervosa has revealed that metabolic differences play an equally important role along with psychological effects in the development of this disease....
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...
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...
