3D PRINTING WITH MARTIAN AND LUNAR DUST-BASED INKS

05 May 17

Researchers from the Northwestern University have demonstrated the potential of 3D printing structures with simulants of Martian and lunar dust. These Martian and lunar dust simulants are NASA-approved, and bear similar particle shapes, compositions and sizes to the dusts on Mars and moon surfaces.

The Martian and lunar 3D paints are made by mixing the respective dusts with different simple solvents, and a biopolymer. And then 3D printing of these with a simple extrusion process is done. The structures thus resulting are more than 90% dust by weight.

Though these are composed of rigid micro-rocks, the final 3D-painted material is elastic, flexible and tough like rubber. This material can be rolled, cut and folded.

Printing is a highly scalable, easy, and sustainable manufacturing method for space travelers. They can use the 3D paints to print various structural and functional objects using the available resources there to make everything from little tools to huge buildings, says the team. The research was published in the Nature Scientific Reports.

Further work is being carried on optimizing ways to heat the 3D structures in a furnace to transform these rubbery, soft things into ceramic-like, hard structures.

A New Revelation of Clay Minerals Found on Mars

11 Dec 17

It has been assumed that large amount of clay minerals on Mars could have been formed later interactions with water on the surface. But this assumption has been nullified by a new research that reveals that it could have been formed after the planet's crust cooled down and took a solid form. Discussing of the possibilities it has been said that in the very early solar system, Mars and other rocky planets are assumed to have been covered by oceans of molten magma.

At the time when the magma ocean began to cool and solidify, water and other dissolved liquids would be evaporated to the surface. It led to the formation of a thick, steamy atmosphere around the planet. It took billions of years to the evolution of the planet. Volcanic activities and asteroid attacks would have covered the clays in some places and burrowed them in others. This process led to the patchy distribution of the clay in a large area that is seen on the planet. It has been said that those clay deposits doesn't require a warm and wet climate on early Red Planet. Scientists also said that the steam atmosphere that is related with the ocean of magma could have survived for as long as 10 million years or more.  There has been a possibility that a lot of water might have locked up in those clays that if heated up by any process, would release that water. It might provide a temporary water supply.

How Education Should be Student Centric

09 Dec 17

Education minister on Thursday said that-Education should be student centric, not teacher centric.

He believes that school libraries should be equipped with books and study material not just accessible to students but also for teachers so that they do not face any problems in clearing doubts of a child. He has a strong belief that the government should work against putting an end to the marginalization of in education. Other than this, he has also proposed setting up talent labs to nurture the talent of each and every child. He says that educating them about the academic syllabus is not enough; instead it is also important that he inculcates other habits too like reading and writing.

Actor/Filmmaker Joy Mathew says that a child should not be categorized as abled or disabled on the basis of their exam performance. Education should be about nurturing talent and not marks or grades.

How Galaxies are Formed

08 Dec 17

Seeing two galaxy merging together has again brought up the question of how exactly the galaxies are formed. In the very initial phase, the galaxies were just tiny dwarfs that clumped together to form larger galaxies which are there today. This is also known as hierarchical formation, which means that galaxy formation is a step-by-step process in which smaller galaxies are pulled together due the gravitational force between them.

Recent discovery has shown that led to rethinking of this theory as it suggests that the dwarf galaxies merge into larger ones a lot faster than it was originally being thought. This has led to the confusion of the formation of galaxies arising again and leaving the researchers confused and making them look back to 13 billion years ago, when all this actually started.

A Different Way to Deal with Lower Back Pain

07 Dec 17

Lower back pain has been considered as the lifestyle problem that is associated with our working pattern and sitting posture. In the digital world of today most of the people spend time sitting near computer that leads to the back pain. They often go to physicians for its treatment. Earlier the doctors used to give pain-killers for that but now a new trend is becoming popular in treating LBP. The physicians are now less interested in recommending pain medicines. Instead of pain medicines, GPs might suggest non-medicinal approaches including yoga, various kinds of physiotherapy and psychological therapies too that will not only cure the pain but energises the patient. Low back pain is a big reason of early retirement and income poverty of a lot of people world-wide. It is also a costly affair to have regular therapy for LBP. Keeping these all things in mind, the UK National Institute for Health and Care Excellence clinical has published the guidelines for low-back pain and sciatica. There is also a clinical practice guideline to encourage a change in thinking about the primary care management of low-back pain at initial stage so that it does not take a worse form. The new guidelines suggest avoiding pain killers at initial stage and discourage other major treatments like injections and surgery for treatment. If this guideline would be followed then it would physicians’ job easier, and would positively affect the lives of many people with low back pain.
