Various Space Mission in last 5 year
1- XMM-Newton- by ESA (X-Ray based) It is the biggest scientific satellite ever built in Europe, its telescope mirrors are amongst the most powerful ever developed in the world

Bacterium called Geobacter shuttles electrons from organic material to metal-based compounds, such as iron oxides.Many other bacteria make protein nanowires to transfer electrons to other bacteria or sediment in their environments.This transfer creates a small electrical current.

Electrical Bacteria
#UPSC
Generating electricity from thin air may sound like science fiction, but a new technology based on nanowire-sprouting bacteria does just that—as long as there's moisture in the air.

[Techqie @upsc_science]

A new study shows that when fashioned into a film, these wires—protein filaments that ferry electrons away from the bacteria—can produce enough power to light a light-emitting diode. The film works by simply absorbing humidity from the surrounding air.

6-Chameleons
Although chameleons are best known for their color-changing ability, they are also able to regenerate. Chameleons can regrow their tails and limbs. They can also heal damaged nerves and skin during the regenerative process.

Regenerative Ability

Few creatures may provide us with insight into how regeneration occurs in their species.
1- Salamander
The salamander is an amphibian with a tail and short legs. There are over 700 species of salamander.

5- Mexican Tetra
The river-dwelling Mexican tetra is a fish that can regenerate heart tissue. Research shows that this fish can generate tissue with no scarring. It could lead to breakthroughs in the field of cardiovascular disease.The zebrafish can also generate its heart.

@drishtiiaseng By seeing statement 2 we can easily identify that it is wrong because it is not possible that any treaty can aims to proliferate the spread of nuclear weapons, so option b and c eliminated...now see statement 1 we can use knowledge and get the answer
Correct Ans- A

5) Purpose of JWT - to look for answer to the question that whether there is life beyond our planet? , to search for evidence of exoplanets, observe formation of stars and galaxies etc.

#JWT
Difference b/w JAMES WEBB TELESCOPE and HUBBLE TELESCOPE.

1) JWT was sent on Christmas of 2021. Hubble was sent in 1990.

4)JWT mirror is much larger than that of Hubble. JWT has unique shield to keep major equipments at cooler temperatures

@drishtiiaseng If you read option carefully you will find that , option 1 says it is non- flammable and in option 3 says it easily catch fire ..thus only one can be correct ,So.Option C and D can be eliminated. Now use elimination technique by your pre existing knowledge
Correct Answer- A.

A vast amount of data can be processed and analyzed with a telematics device such as:

1-Position
2-Vehicle speed
3-Trip distance/time
4-Idling time
5-Harsh braking and driving
6-Seat belt use
7-Fuel consumption
8-Vehicle faults
9-Battery voltage, and other engine data.

Telematics
#telematics is a term that combines the words telecommunications and informatics to describe the integrated use of communications and information technology to transmit,store and receive information from telecommunications devices to remote objects over a network.

[Techqie @upsc_science]

There are several key components of a telematics device:
1-GPS receiver
2-Engine interface
3-Input/output interface (expander port)
4-SIM card
5-Accelerometer
6-Buzzer #upscscience
