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...
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...
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...
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....
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...
MicroRNAs or in short miRNAs (not to be confused with mRNA or messenger RNA) were discovered in 1993 and have been extensively studied in the past two decades or so for their role in regulating gene expression. miRNAs are...
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...
Advanced age and comorbidities are known to be high risk factors for COVID-19. Does genetic make-up predispose some people making them more susceptible to severe symptoms? Conversely, does genetic make-up enable some people to have innate immunity making them...
The plant derived agent, Thapsigargin (TG) has been used in traditional medicine for long time. TG has shown promises as a potential anti-cancer drug because of its biological property to inhibit the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) pump which is necessary for...
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...
The seven planets in the stellar system of TRAPPIST-1 are similar in densities.
Stars in the galaxies have stellar systems comprising mainly of their planets and satellites. For example, our home stellar system viz. solar system has nine planets...
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...
PHILIP: Laser-Powered Rover to Explore Super-Cold Lunar Craters for WaterHuman settlements beyond Earth on Moon or on planets like Mars in space have long been the theme of science fiction. However, serious thoughts and research activities towards this have...
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...
A novel mechanism to explain the different unrelated symptoms of COVID-19 has come to light by exploiting the second fastest Supercomputer in the world known as Summit supercomputer at Oak Ridge National Lab in Tennessee. The study involved analysing 2.5...
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.
