NEWater is treated wastewater that has been purified using microfiltration, reverse osmosis, and ultraviolet technologies to produce potable water. It is mostly used for industrial purposes but is also consumed by humans. The water undergoes biological and chemical treatment at a water reclamation plant before microfiltration removes solids. Reverse osmosis then removes molecules and ions through pressure and selective membranes. Finally, ultraviolet light further purifies the water. Singapore has invested in NEWater since the 1970s and now has 5 plants producing 30% of its water, with a goal of 50% by 2060.
The Ultra Violet purifier completely removes chemical and biological contaminants like chlorine, fluorides, viruses, bacteria, and micro-organisms from water. The purification process involves several stages including sand filtration, sediment filtration, carbon filtration, ultraviolet treatment, and flow control. Water treated by this prototype device was tested at a water analysis center and found to remove contaminants. Once testing is complete, the purifier will be distributed to flood affected areas and used on the college campus.

Empathetic innovations for closing the social technological gap: Honey Bee Network Model
Inclusion of bypassed spaces, sectors, skills and social segments in developmental agenda has rightly engaged the attention of world technology leaders. But this inclusion in the true sense, may not happen unless we begin to learn from grassroots innovators and communities and blend formal and informal S & T systems. This has been the mission pursued by The Honey Bee Network, a social movement for the last twenty five years. The heuristics of sustainable frugal innovation will not emerge from a jugaad (makeshift) mentality. These will require an empathetic understanding of affordability, accessibility, availability, rejuvenability, durability and circularity of products and services. Designing new solutions by building upon artefactual, metaphorical, heuristic and gestalt aspects of innovation will fertilise our imagination, enrich scientific inquiry and result in reciprocal, responsive, and responsible relationship with knowledge rich- economically poor, creative communities.
The document discusses the Honey Bee Network, an initiative that aims to connect grassroots innovators and traditional knowledge holders with investors, entrepreneurs, scientists and others who can help develop and disseminate their innovations. It outlines the network's goals to overcome barriers like language and provide open access collaboration platforms. It also discusses challenges such as many innovations only being at proof-of-concept stages and the lack of common design languages. The network works to bridge formal and informal science and foster partnerships between innovators and high-tech networks to augment green grassroots innovations.
World population is growing continuously with more people living on the Earth than ever before. In 2007, humanity’s total ecological footprint was estimated at 1.5 planet Earths. Resources are becoming increasingly valuable as the Earth is the only source till date and others planets are still to become a viable source of these resources.
Projections estimate that we will need the equivalent of two planets by 2030 to meet our annual demands. The only way, we can reduce our footprint is by producing more with less, and consuming better, wiser and less - the way forward is better and 'frugal' choices!
In this report, we present the trends that encourage better choices; trends in Frugal Innovations, 'Jugaad' and Do-It-Yourself are explored to see how and where we can make our better choices for the future.
We conclude our report with 3 thought provoking future scenarios.

Domestic Wastewater Treatment by Root Zone Technology Option: Colacassia PlantDr. Amarjeet Singh
Root Zone Technology is one of the low cost
methods to treat wastewater. With the help of this system we
can treat the Non-Point sources with best results. To achieve
this goal we have to divide the Non-Point sources into
constructed channels within the river bank followed by root
zone bed or if the Non-Point Sources is coming from natural
nallas we can provide this system within its Channel. We
have prepared channel on which I have developed the root
zone bed and have lab analysis of rector out put on number
of parameters. Flow rate and Detention time are the two
factors on which channels are to be designed. Therefore I
am changing the flow rate and finding out the change in
parameter with respect to detection time. The optimization
is when we get best result with maximum flow. I have got
satisfactory results for the detention time of Three day,
Seven day and twenty one day and Three day. With the help
of this data I have designed the root zone bed system for the
selected actual Domestic Sources.

This document discusses coronaviruses, including their classification, structure, replication process, transmission, and diseases they cause. Coronaviruses are spherical or helical viruses 80-220nm in diameter that contain a positive-sense RNA genome. They have spike, envelope and membrane proteins and enter host cells by fusing with the cell membrane. The RNA is then translated and new viral proteins are assembled and released via exocytosis. Coronaviruses are transmitted through respiratory secretions and cause up to 15% of common colds as well as more severe diseases like MERS, SARS, pneumonia, and gastroenteritis.
The plasma membrane is a phospholipid bilayer that forms the boundary of cells. It is selectively permeable, allowing some substances to pass through more easily than others. Early models proposed that proteins were sandwiched between phospholipid layers, but the fluid mosaic model established in 1972 described proteins as being dispersed within and moving laterally through the fluid phospholipid bilayer. Membrane proteins have important functions including transport, enzymatic activity, signal transduction, cell-cell recognition, intercellular joining, and attachment to intracellular and extracellular structures. Membranes are synthesized in the ER and Golgi apparatus and their structure results in the selective permeability that allows cells to exchange materials with their surroundings.

Golden rice is a genetically engineered rice variety developed to address vitamin A deficiency. It contains beta-carotene, which the body converts to vitamin A. It was created by introducing two genes - one for phytoene synthase from daffodils and one for lycopene cyclase from soil bacteria. These genes allow golden rice to produce beta-carotene in the endosperm. Golden rice breeding programs are working to introduce it into popular rice varieties in countries with widespread malnutrition. The goal is to help reduce symptoms of vitamin A deficiency like blindness and increased disease susceptibility. While golden rice could help address malnutrition issues more sustainably than supplements, some disadvantages include potential allergies, reduced biodiversity, and
This document discusses how CD4+CD25+ regulatory T cells (Tregs) suppress natural killer (NK) cell-mediated anti-tumor immunity. Specifically, it finds that Tregs directly inhibit NKG2D-mediated NK cell cytotoxicity in vitro and in vivo through a transforming growth factor beta (TGF-β)-dependent mechanism. This suppression of NK cell function by Tregs effectively inhibits NK cell-mediated tumor rejection. The document explores this finding through experiments isolating spleen NK cells, Tregs, and tumor cell lines and analyzing their interactions both in vitro and in vivo in mouse tumor models.
This document summarizes a study that investigated the cytotoxic effects of two microbial biosurfactants (S9BS and CHBS) against human embryonic kidney cancerous cells (HEK-293). The biosurfactants were found to exhibit cytotoxic effects against the HEK-293 cells in a dose-dependent manner based on MTT assays. Morphological changes and apoptosis were observed in the biosurfactant-treated cells compared to untreated cells. FACS analysis further confirmed the role of apoptosis in the biosurfactant-induced cytotoxicity through increased sub-G1 cells. The study demonstrates the potential for these microbial biosurfactants as anticancer agents through membrane disruption and apoptosis induction in cancer cells.

2. Manav (robot)
India's first 3D-printed humanoid robot
Manav is India's first humanoid
robot which was developed in the
laboratory of A-SET Training and
Research Institutes by Diwakar
Vaish (Head
of Robotics and Research, A-SET
Training and Research Institutes)
in late December 2014. It
debuted at the IIT-
Bombay Techfest 2014-15
in Mumbai
3. • Manav stands at 2 feet tall and has a weight of 2 kilograms. It is
equipped with onboard sound processing and visual processing.
• Thanks to the onboard processor and various sensors, Manav can
perform various activities like walking, dancing with the only
requirement of human voice commands.
• Manav's outer body was designed in A-SET's own 3D
printing laboratory and is made of Acrylonitrile butadiene
styrene plastic.[2][3][4][5][6]
• Manav has a total of 21 degrees of freedom,
• The robot comes with a rechargeable Lithium polymer
battery which can keep it running for one hour.
• The robot is also equipped with Wi-Fi and Bluetooth connectivity.
4. Jamun seed-made water purify
by IIT Hyderabad
• Using a jamun seed based 'Activated Carbon', the researchers
demonstrated that they could bring down fluoride to levels that were
considered acceptable by the World Health Organisation (WHO)
• Jamun seed was converted to highly porous carbon material by
chemical treatment followed by processing at higher temperatures to
improve its efficiency. Initially, trials were carried out with the
obtained material for synthetic fluoride solutions prepared in the
laboratory.
• Post-treatment, the researchers observed that the fluoride
concentration was reduced to the acceptable limit of WHO, which is
less than 1.5 mg/litre.
8. Self-Repairing Roads
• Innovation by: Nemkumar Bhantia
• Unlike the typical concrete road, in which cement is a key
component, Banthia’s self-repairing road uses 60 % fly-ash
and only 40 % cement. The fibres used have a hydrophilic
nano-coating, which attract water in the event of rains. The
water then becomes a key component in healing cracks.
When a crack appears, this water gives hydration capability
to the un-hydrated cement, and produces more silicates,
which actually close the crack before they grow larger.
9. The first such road in Karnataka is not only
cost-effective, but has greater longevity
10. Envigreen Edible Bags
• India has been moving away from plastics for many years and many
cities have already issued plastic bag bans. While legislation like this
helps to protect our environment and wildlife, a young
entrepreneur, Ashwath Hegde, noticed that it was a hardship for
many Indians.
11. He eventually landed on a combination
of natural starch (from potato and
tapioca) and vegetable oils to make a
bag that looks and feels just like plastic
with none of the negative environmental
impacts of a plastic
vessel. EnviGreen‘s bags will naturally
degrade in 180 days and if they are
submerged in water they disappear in a
day. Oh and also – these bags are edible.
This means that when animals
encounter non-degraded bags, they can
eat them with no adverse effects.
12. Solar Power Tree
• Developed by the Central Mechanical
Engineering Research Institute (CSIR-
CMERI), the Solar Power Tree
generates the same amount of
electricity as a conventional array
(enough to light up 5 homes), but on
a much smaller plot of land. With
photovoltaic panels placed at
different levels on branches made of
steel, “solar trees” could dramatically
reduce the amount of land needed to
develop solar parks.
13. Solar power trees are also capable of harnessing 10 to 15 percent more
power compared to ground-mounted solar arrays. The tree charges a
battery backup system that can provide two hours of light after sunset
on a full charge. The solar tree is also self-cleaning, with a built-in water
sprinkler to clear any debris that would interfere with efficiency
14. Institute of Life Sciences Scientists Develop
Antibodies Against Chikungunya
The Institute of Life Sciences (ILS), Bhubaneshwar research
team has successfully developed antibodies against the
Chikungunya viral (CHIKV) infection, after which it has entered
into a non-exclusive license for product commercialization.
15. The antibodies were created
following decade-long
research on the CHIKV
disease at the ILS lab
headed by Dr. Soma
Chattopadhyay, a senior
molecular virologist. Dr.
Chattopadhyay was chosen
for its Biotech Product,
Process Development and
Commercialisation Award
2019 from the Department of
Biotechnology.
