Multiple trackways with about 200 dinosaur footprints have been discovered on a quarry floor in Oxfordshire. These dates to the Middle Jurassic Period (around...
The thylacine de-extinction project announced in 2022 has achieved new milestones in generation of the highest quality ancient genome, marsupial genome editing and new...

Fossils of ancient chromosomes with intact three-dimensional structure belonging to extinct woolly mammoth have been discovered from 52,000 old sample preserved in Siberian permafrost....
Tmesipteris oblanceolata , a type of fork fern native to New Caledonia in the southwest Pacific has been found to have the genome size of...
The German cockroach (Blattella germanica) is world’s most common cockroach pest found in human households worldwide. These insects have an affinity for human dwellings...
Interspecies Blastocyst Complementation (IBC) (i.e., complementation by microinjecting stem cells of other species into blastocyst-stage embryos) successfully generated rat forebrain tissue in mice which...
Biosynthesis of proteins and nucleic acid require nitrogen however atmospheric nitrogen is not available to eukaryotes for organic synthesis. Only few prokaryotes (such as...
A new species of sea slug, named Pleurobranchaea britannica, has been discovered in the waters off the southwest coast of England. This is the...
Bacterial dormancy is survival strategy in response to stressful exposure to antibiotics taken by a patient for treatment. The dormant cells become tolerant to...
The brine shrimps have evolved to express sodium pumps that exchange 2 Na+ for 1 K+ (instead of the canonical 3Na+ for 2 K+)....
The word ‘robot’ evokes images of human-like manmade metallic machine (humanoid) designed and programmed to automatically perform some tasks for us. However, robots (or...
Kākāpō parrot (also known as “owl parrot” because of its owl-like facial features) is a critically endangered parrot species native to New Zealand. It...
Parthenogenesis is asexual reproduction in which genetic contribution from male is dispensed with. Eggs develop to offspring on their own without being fertilised by...
Some organisms have ability to suspend life processes when under adverse environmental conditions. Called cryptobiosis or suspended animation, it is a survival tool. Organisms...
“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...
Extinct gigantic megatooth sharks were at the top of the marine food web once. Their evolution to gigantic sizes and their extinction are not...
The traditional grouping of life forms into prokaryotes and eukaryotes was revised in 1977 when rRNA sequence characterisation revealed that archaea (then called 'archaebacteria')...
Unlike conventional mRNA vaccines which encodes only for the target antigens, the self-amplifying mRNAs (saRNAs) encodes for non-structural proteins and promotor as well which...
Scientists have replicated the natural process of mammalian embryonic development in the laboratory up to the point of development of brain and heart. Using...
RNA ligases play an important role in RNA repair, thereby maintaining RNA integrity. Any malfunction in RNA repair in humans seems to be associated...
Ever changing environment leads to extinction of the animals unfit to survive in the changed environment and favours survival of the fittest which culminate in...
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...
A new, complete dataset of comprehensive functional trait for all birds, called AVONET, containing measurements of more than 90,000 individual birds has been released...
