BATS HARBOR MANY VIRUSES Focus: Prelims, GS-3

Why in news?

Bats are being considered as a vector for Novel Coronavirus

Details: 





Bats serves as natural hosts for numerous viruses including Ebola virus, Nipah virus, coronaviruses such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) and the 2019 novel coronavirus that has infected nearly 10,000 people and killed over 350 others.

Still they don’t get infected because bats can avoid excessive virus-induced inflammation, which often causes severe diseases in animals and people infected with viruses According to journal Nature Microbiology  The inflammatory response is dampened in bats immaterial of the variety of viruses that are present and the viral load.



Significantly reduced inflammation in bats was because activation of an important protein — NLRP3.

Reduced activation of the NLRP3 protein was in turn due to impaired production of mRNA (transcript). Since mRNA production is impaired the NLRP3 protein production gets compromised leading to less amount of the protein being produced.

Further analysis comparing 10 bat and 17 non-bat mammalian NLRP3 gene sequences confirmed that these adaptations appear to be bat-specific.

CHEER FOR SCIENCE AS KEY DEPARTMENTS GET A RAISE Focus: GS-3

MORE MEN THAN WOMEN IN STEM Focus: GS-3

Why in news?

Masculine culture, insufficient early exposure to science play a role

Details:  



 



Across the world, there are more men who are active in science, technology, engineering and medicine (STEM) than women In the labour market, or in places where high level qualifications are demanded, men candidates engage in self-promotion, and are boastful while equally qualified women are more ‘modest’ and ‘undersell’ themselves.

Even in groups and situations where men and women are present as colleagues, the views of women are either ignored or listened to less seriously than those of men.

As a result, women tend to underestimate their ability relative to men, especially in public settings, and negotiate less successfully.

Three socio-psychological reasons, namely (1) masculine culture, (2) lack of sufficient early exposure to computers, physics and related areas compared to boys in early childhood and (3) gender gap in self-efficacy.

Stereotyping that men are fitter for certain jobs and skills than women, and that women are more ‘delicate’, ‘tender’ and thus unfit for ‘hard’ jobs.

NASA DECOMMISSIONS SPITZER SPACE TELESCOPE AFTER 16 YEARS OF OPERATION Focus: GS-3, Prelims

Why in news?

Spitzer, which was launched in 2003, studied some of the most distant galaxies ever detected with the light from some of the cosmic bodies travelling for billions of years to reach the telescope, NASA said.

Details: 

SHAHEEN FALCON SPOTTED IN THIRUVANANTHAPURAM Why in news?  

It was the first reported sighting of the fastest bird in the world in the capital city Also Known as Indian Peregrine Falcon, it is the fastest bird in the world

Daily Current Affairs Dated on 03-Feb-2020 



 

Peregrine falcons are usually found along mountain ranges and river valleys, but it is not unusual to find them in cities, especially in high rises where they are able to find prey like pigeons and other small birds very easily.

They usually build their nest in the mountain cliffs, which also serve as ambush points for them to wait for the prey and launch the aerial assault after spotting the same.

The distinguishing mark that separates Shaheen Falcons from Peregrine is the white color around their throats.

The bird is usually spotted alone and Peregrine falcons are known to mate for life — like hornbills.

WHY IS THE CHEETAH EXTINCT IN INDIA? Details: 

 







At the recent meeting of the Conference of Parties to the United Nations Convention to Combat Desertification (UNCCD COP 14), a researcher from the Indian delegation pronounced desertification as the primary cause of the extinction of the cheetah (and also the still-extant great Indian bustard) in India.

Two idiosyncratic traits of the animal undeniably led to its end: One, the cat was very easy to tame: it was often trained to race down and hunt animals, almost like a hound — a ‘sport’ called coursing — and so was caught in large numbers for use in such hunts. Second, cheetahs were nearly impossible to breed in captivity.

Breeding captive cheetahs was such an incredible rarity that in 1613, Emperor Jahangir formally recorded the first and only instance, up to the 20th century, of a cheetah bred in captivity anywhere in the world in the book Tuzuk-iJahangiri.

The earliest reference to their domestication for the sport of coursing is from Manasollasa, the 12th century chronicle of the court activities of King Someshvara III of Kalyani Such was the scale of cheetahs being taken out from the wild that Emperor Akbar is said to have acquired a staggering 9,000 cheetahs for his royal menagerie during his 49-year reign in the 16th century

There is just a single record of a human fatality from a cheetah attack that we know of — the death of O.B. Irvine, Agent of Governor in Visakhapatnam, who died after being mauled by a captive cheetah that belonged to the Raja of Vizianagaram, during a coursing hunt in 1880 In fact, the term ‘Asiatic cheetah’ gained currency only after the species’ extinction in India; before this, it was known as the Indian cheetah.

The earliest visual evidence of the Asiatic cheetah, dating back to 2500 to 2300 BCE, is found in cave paintings in Kharvai and Khairabad, and in the upper Chambal valley, in Madhya Pradesh.

PROLONGED MONSOON REVIVES WATERHOLES IN BANDIPUR Why in news?
