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...
Cells with fully artificial synthesized genome were reported first in 2010 from which a minimalistic genome cell was derived that showed abnormal morphology upon cell division. Recent addition of a group of genes to this minimalistic cell restored the...
Launched on 30th July 2020, Perseverance rover has successfully landed on the Mars surface at Jezero Crater on 18th February 2021, after travelling almost seven months from Earth. Designed specially to collect sample of rocks, Perseverance is the biggest and the best rover ever...
Solar wind, the stream of electrically charged particles emanating from the outer atmospheric layer corona of Sun, poses threat to life form and electrical technology based modern human society. Earth’s magnetic field provide protection against the incoming solar wind...
The Nebra Sky Disk has inspired the logo of the space mission ‘Cosmic Kiss’. This space mission of the European Space Agency is the declaration of love for space.
Ideas from observation of night sky played important role in religious beliefs...
A recent study has revealed that all the seven exoplanets in the stellar system of TRAPPIST-1 have similar densities and Earth-like composition.This is significant because it builds the knowledge-base for a model of understanding of Earth-like exoplanets outside of solar...
The researchers from the Sloan Digital Sky survey have reported most detailed look at the warp of our home galaxy
Usually, one think of spiral galaxies as a flat disc rotating around its centre but about 60-70% of the spiral galaxies including...
Situated about 600 miles west of coast of Ecuador in Pacific Ocean, Galápagos volcanic islands are known for its rich ecosystems and endemic animal species. This inspired Darwin’s theory of evolution of species. It is known that rising up...
New research expands role of Earth’s magnetic field. In addition to protecting Earth from harmful charged particles in incoming solar wind, it also controls how the energy generated (by charged particles in solar winds) is distributed between two the...
Gravitational wave was directly detected for the first time in 2015 after a century of its prediction by Einstein’s General Theory of Relativity in 1916. But, the continuous, low frequency Gravitational-wave Background (GWB) that is thought to be present throughout the...
NASA recently released the spectacular bright image of the firework galaxy NGC 6946 taken earlier by Hubble space telescope (1)
A galaxy is a system of stars, remnants of stars, interstellar gas, dust, and dark matter that are bound together...
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...
The findings of the BioRock experiment indicate that bacterial supported mining can be carried out in the space. Following the success of BioRock study, the BioAsteroid experiment is currently underway now. In this study, bacteria and fungi are being grown on asteroidal material in an incubator under...
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...
Astronomers usually get to hear from the far-off galaxies through high energy radiations like X-rays. It is extremely uncommon to receive relatively lower energy UV radiation from ancient galaxies like AUDs01. Such low energy photons usually get absorbed on...
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...
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,...
Hunter gatherers are often thought of as dumb animalistic folks who lived short, miserable lives. In terms of societal advancements such as technology, hunter gatherer societies were inferior to modern civilized human societies. However, this simplistic perspective prevents individuals...
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...
NASA’s ambitious mars mission Mars 2020 was successfully launched on 30 July 2020. Perseverance is the name of the rover.
The main task of Perseverance is to seek signs of ancient life and collect rock and soil samples for possible return to Earth.
Mars is cold, dry...

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 origin of sarsens, the larger stones that make the primary architecture of Stonehenge was an enduring mystery for several centuries. The geochemical analysis1 of the data by a team of archaeologists has now shown that these megaliths originated from...
NASA’s infra-red observatory Spitzer has recently observed the flare from gigantic binary black hole system OJ 287, within the estimated time interval predicted by the model developed by astrophysicists. This observation has tested different aspects of General Relativity, the...
‘’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...
