In this article, we will share 5 amazing facts about spacex’s starship rocket, that distinguishes it from other launch systems. 1.    Starship can Refuel in Space Fuel is perhaps the most important thing that every space agency needs to consider. Many of the space shuttles and rockets find their way to the scrapyard due to their non-reusability. But things are different with spacex starship. Starship will have the capability to refuel in space. This means that you don’t need excessive loads of fueling in a rocket for long ve...

Scientists find first multicellular living organism that can survive without the availability of oxygen

-

This organism bid farewell to aerobic respiration a long time ago.




Living organisms with the capability to exist without the involvement of oxygen is a little bit controversial. Our current knowledge revolves around oxygen being the key element used by all living organisms present on this planet for survival. Recent research shows that some microbial organisms can withstand the oxygen-deficient environment.  

H. Salminicola is a member of Phylum Cnidarian to which jellyfish and sea anemones also belong. H. Salminicola is parasitic and can commonly dwell inside Salmon fish, but it’s not harmful to its host and will usually remain inside the fish throughout its life cycle.

Recent research conducted on this organism revealed that it lacked the conventional life apparatus known as ‘Mitochondria”, which is involved in the production of energy-rich molecules known as ATP. It is due to this energy-rich molecule that we occasionally designate mitochondria as the powerhouse of a cell.

Findings that made this organism centre of attraction

Upon analysis, H.Salminicola revealed very little regarding its capabilities in severely hypoxic conditions. Scientists used deep sequencing and fluorescence techniques to take a closer look at the genome of the organism. These examinations revealed that H.Salminicola had lost crucial mitochondrial genes associated with respiration. 

Lack of mitochondrial genes deprived H.Salminicola of oxygen driven respiration. Instead of developing mitochondria, H.Salminicola evolved with some unusual structures whose functionalities closely resemble with mitochondria.
 

Myxobolus squamate, another microscopic organism closely related to H. Salminicola, appeared as a control group and possessed all mitochondrial genome. These results further proved that H.Salminicola is the first multicellular organism with an oxygen-independent mechanism. Researchers working on this mysterious organism believe that it used to possess the required genome but somehow lost it over time.


Prof. Dorothee Huchon, who led the study, said.

“Aerobic respiration thought to be ubiquitous in animals, but now we confirmed that this is not the case,”


Why is this finding important?

According to this research, we’ve discovered a life-form that can sustain even in the complete absence of oxygen. This discovery proves that life can nurture in oxygen-deprived conditions, vindicating the prospect that life exists on other planets.

Coronavirus outbreak: How much transmissible is this virus?

What is the Coronavirus and why is it difficult to restrain it? Coronavirus is common in animals and has some forms that don’t even affect humans. This same virus is responsible for causing two well-known diseases named SARS and MERS in the outbreaks of 2002 and 2012 respectively. Due to complicated mutation capabilities these viruses become very unpredictable. This feature of the virus makes it a mystery for the scientists who are constantly trying to sequence its genetic material for vaccine production. Transmission of the virus and common symptoms The latest diseases caused by Coronavirus has been named COVID-19 and is said to have caused the pneumonia-like condition in its victims. Like the others this Coronavirus is said to have been transmitted from wildlife to humans.  Its being said that the virus made its way to its human host from a seafood market located in Wuhan province of China. This new coronavirus is much more dangerous than the seasonal flu that...

Perseverance rover lands on mars: NASA releases breathtaking images of the red planet!

NASA has succeeded in piloting its Perseverance Mars rover on the surface of the red planet. Mission control burst into celebration after the Perseverance rover landed at Jezero crater on Mars. Perseverance mars rover will now spend the next two years drilling rocks at Jezero crater. During this time, it will expect to find signs of antique life. Previously the mars orbiters used to capture images of the Jezero crater from about 200 kilometers above. It was sufficient for topographical analysis. But to search for life, earthlings needed rover-like perseverance.  Perseverance sends first colored picture after touchdown on Mars Jezero crater supported ancient lakes, and there are high potentials for hunting down traces of microbial life. This Crater is 28 miles or 45 kilometers wide and sits on the western edge of sides Planitia. It is a giant basin north of the Martian equator. It is said to have formed after a gigantic rock from space smashed through the Martian surface.  A re...
