NASA’s plan for Asteroids?
- NASA scientists are planning to capture a 500,000 kg asteroid, and transform it into a space station for astronauts to refuel at on their way to Mars.
- This technology would also open up the possibility of mining other asteroids for their metals and minerals.
- Some asteroids are full of iron which could be used for in the making of new space stations
- Others asteroids are made up of water which could be broken down into hydrogen and oxygen to make fuel
- NASA plans to accomplish this in next 10-12 years.
- Mercury is the innermost planet in the Solar System.
- NASA’s MESSENGER spacecraft has reported presence of water-ice on Mercury.
- GRAIL (Gravity Recovery and Interior Laboratory) mission.
- It is NASA’s first planetary mission to carry cameras fully dedicated to education and public outreach.
- MoonKAM= Moon Knowledge Acquired by Middle School Students.
- The MoonKams captures images of the moon’s surface and sends them to the students for study.
- Two NASA spacecraft — Ebb and Flow, equippped with MoonKAMs and orbitting around Moon since 2011 under GRAIL mission.
- But they did not have sufficient altitude or fuel to continue science operations. Hence NASA team crash-landed them on Moon in Dec 2012.
- The place where they crash landed is named after Sally K. Ride, America’s first woman astronaut.
- A coating material for any type food containers —glass, ceramic, metal and plastic.
- It is super-slippery and non-toxic hence you can easily pickout last drop of honey, fruitjam, ketchup or oil from the insides of food containers.
- No scraping, rinsing of bottles required.
- And the compound is safe enough to eat.
- Keep ice off the wings of an airplane
- Help easy flow in oil and gas pipelines where insides of pipes sees buildup of organic compounds that clog supply networks.
- For cosmetics: can pour last drop of expensive lotions out.
- a new kind of light bulb that uses plastic polymers and nano materials to generate light
- It is more energy-efficient than current fluorescent lights and is easier on the eye.
- It doesn’t produce humming sound like those fluorescent tubes.
Nuclear Desalination Demonstration Plant (NDDP) located at Kalpakkam, Tamilnadu.
It is the world’s largest hybrid seawater desalination plant coupled to an existing nuclear power plant.
- when the pressure drops, the boiling point of seawater also drops.
- The excess heat generated from nuclear reaction causes seawater to flash evaporate into pure water vapour.
- The water vapour is then condensed to produce distilled water.
- desktop-size 3-D printer.
- Instead of using ink, it spreads ultra-thin plastic layers, each melting into the layer below to create a 3D-object.
- It’s a kamikaze (suicide bombing) type drone.
- The person controlling it uses a real-time video feed from the drone to crash it into a precise target—say, a sniper and its tiny warhead detonates on impact.
- Japan has created three atoms of the highly unstable superheavy element 113.
- This element is yet nameless, but it has an enormous nucleus containing 113 protons and 165 neutrons.
- Pigeonpea, commonly known as redgram, arhar or tur,
- It is leguminous plant.
- it is capable of fixing atmospheric nitrogen and thereby restores nitrogen content in the soil.
- Its deep rooting system helps in extracting nutrients and moisture from deeper soil layers thus making it suitable for rainfed condition.
- Deeper rooting system of the crop also helps in breaking the tough dry soil and it is also called as ‘biological plough’.
- Genuine Handheld X-ray sets are very expensive. But now Chinamade Cheaper products are in the market.
- But they do not have adequate shielding in the X-ray tube.
- And leads to accidental leakage radiation.
- In India, use of such medical X-ray instruments need approval from Atomic Energy Regulatory Board. (AERB)
- Use of radiation generating equipment not approved by AERB is a violation of the legal provisions and will attract action under the appropriate provisions of the Atomic Energy Act 1962
- Histamine =chemical mediator involved in the allergic reactions.
- Histamine dilates blood vessels to facilitate the entry of immune cells onto the wound site to ward off infection.
- But It also acts on the nerve endings causing itching.
- Itching can also be caused due to allergy for the ointments/ medications applied
- When new skin that is formed is devoid of the normal oil glands .This dryness also provokes the nerve endings causing itching.
- It’s the first Do It Yourself testkit for detecting HIV—the same one that health professionals use but without the trip to a doctor’s office or the need to wait days for results.
- is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons).
- Researchers have now derived dopaminergic neurons from bone marrow stem cells in monkeys to cure it.
