Education plays an important role in broadening our perspective, bringing rationality in our thought process, providing opportunity for self-growth, transforming us into a responsible citizen, and preparing us to actively take part in nation-building activities.

It, however, requires meticulous planning at both micro and macro level by governmental and non-governmental bodies to encourage people from different socio-economic strata for their contribution in education system. Using scientific tools and training methodologies to impart education, encouraging parents to send their wards to schools, social security, making education cheaper and affordable to poor, ensuring quality education and teaching standards through proper guidance and monitoring, etc are some of the measures that can ensure higher enrolments in educational institutions along with qualitative output. Let us hope for greater participation of technology-driven younger generation in bringing about a change in our education system through innovative ideas, technological advancements, and leadership skills, and take the nation towards a better and prosperous future.

NASA Grows Edible Vegetables in Space for the First Time
For the first time, NASA has managed to grow red lettuce on international space station. Using its vegetable production system, the NASA unit has produced salad type crops to provide the crew with palatable, nutritious, and safe source of fresh food. The vegetable production system called Veggie provides lighting by using red, green and blue LEDs, and utilizes the cabin environment for temperature control and carbon dioxide sources to support growth of vegetables.

The ‘Veggie’ unit features a flat panel light bank that includes red, blue, and green LEDs for plant growth and crew observation. Using LED lights to grow plants was an idea that originated with NASA in the late 1990s. It was discovered that blue and red wavelengths are the minimum requirements to get acceptable plant development. Surprisingly, the green LEDs simply help in augmenting the human visual perception of the plants, but aren't needed as much as the other two.

Currently, the astronauts need to clean the leafy greens with citric acid based sanitizing wipes before consuming them. The ‘expedition 44’ crew members can only eat half the crop and set aside the other half to be packaged and frozen on the station until it can be returned to earth for further scientific analysis.

This discovery can be a crucial step because it will provide future pioneers with a sustainable food supplement which will be a vital part of their journey to Mars. The NASA veggie project will also help with vegetable production back on earth and can be applied in urban plant factories where electrical light and water conservation is needed.

Graphene Gets a New Competitor--Phosphorene
Graphene currently sits atop the list of wonder materials in the engineering domain. The single layer of carbon atoms in this material exhibits unique electrical properties as well as incredible physical strength and flexibility. These characteristics have enabled researchers to use it in everything from phone chargers to water filters. But it disappoints along one dimension: graphene is not a natural semiconductor. Although engineers are forging ahead to find ways to manipulate it so that it can work in transistors–devices that modify electric currents to power gadgets–they are also now turning to a promising alternative with a similar structure: a single layer of black phosphorus atoms called phosphorene.

Under high pressure, phosphorus becomes black phosphorus, a material with superconductive properties. Recently, a team of researchers at Purdue University isolated just one layer of black phosphorus atoms. Since then, others in the field have started investigating phosphorene.

The excitement has mounted over phosphorene's potential to replace less efficient materials in electronics. Black phosphorus is a “bona fide semiconductor”, meaning its conductivity can be switched on and off. Because of this exceptional property, engineers can control the amount of energy flowing through phosphorene across many orders of magnitude. Such control over energy leakage will help minimize the amount of current that leaks out, which will bring the transistors a step closer to perfect efficiency. Since phosphorene is less brittle than silicon, it could appear in flexible electronics; and also it emits lights, it can be used for lasers or LEDs.

3D Printing Human Skin to Test Cosmetics
Beauty brand L'Oreal is 3D printing human skin tissue in order to test cosmetics. The company has partnered with bioprinting specialist Organavo which can produce living human tissues that mimics the form and function of native tissues in the body, citing boundless potential for new types of tests. Organavo's bioprinting process involves first establishing the design of a particular tissue and then developing "bio-ink" -- the multi-cellular building blocks from the cells that will be used to build the tissue. The bioprinter dispenses the bio-ink in layers, allowing the tissue to be built up vertically. L'Oreal already has its own business unit dedicated to engineering in vitro skin tissue, but it is quite keen to experiment with newer, more efficient and potentially less costly engineering methods. The main benefit of 3D printing the skin over other in vitro engineering methods is that it allows the tissue to be fully 3D rather than 2D.

Organavo has broken new ground with 3D bioprinting, an area that complements L'Oreal's pioneering work in the research and application of reconstructed skin for the past 30 years. It will not only bring new advanced in vitro methods for evaluating product safety and performance, but the potential where this new field of technology and research can take us is boundless too.
