India Science Wire - highlighting Indian science in Indian
media
The coverage of science and technology particularly relating to
research done in
Indian research institutions, is generally very poor in Indian
media. There are
several reasons for this situation, one of them being the lack of
credible and
relevant science content. In order to bridge this gap, Vigyan
Prasar launched a
unique initiative - India Science Wire (ISW) – in January
2017.
The news service is dedicated to developments in Indian research
laboratories,
universities and academic institutions. Almost all news stories
released by this
service are based on research papers by Indian scientists published
in leading
Indian and foreign journals. All news stories and features are
written and edited by
a team of professional science journalists with decades of
experience in science
journalism.
News stories based on happenings in Indian research labs are
released to media
houses on a daily basis. These stories are also uploaded on ISW
website and are
simultaneously promoted though social media – Twitter and Facebook.
At present,
the service is available in English and Hindi.

The purpose is to enhance the crop yield in lesser time
By Jyoti Singh Published: Thursday 06 August 2020
Microbes always exist in communities. They are also used in
commercial applications. In industries like probiotics and
biofuels, co-cultivations of these microbes are performed under
controlled conditions for improved yield and productivity of the
given product. These co-cultures are designed randomly based on hit
and trial methods.
To quickly ascertain the right combination and to understand how
these microbes interact with in a co-culture, researchers from the
Indian Institute of Technology (IIT) Madras have developed and
demonstrated an effective method.
The study applies computer-based modelling to develop novel
algorithms to identify metabolic interactions between bacteria.
This understanding may help in identifying the perfect combination
for a co-culture.
“There is no rational way to identify the co-culture to begin with.
This is a more rational way of designing the co-cultures. We will
extend the applications to plants productivity too. The purpose is
to enhance the crop yield in lesser time,” Smita Srivastava,
associate professor, Department of Biotechnology, IIT Madras,
said.
The research shows that many metabolites act as messengers between
the microbes. These messengers are critical to define how bacteria
associate with one another and what combination is best suited for
co-cultures. The interactions also play a significant role in a
wide variety of applications ranging from probiotic design to
biofuel production.
According to the researchers, one of the applications is focused on
the agriculture industry. It might be able to get certain
metabolites which may be utilised by the plants for its growth.
“How the plant can interact with certain organisms which are known
in nature to live with the plant when we try to exploit that in
reactor system, it will help in over producing that product from
the plant,” Srivastava said.
The team plans to extend the findings of this study to investigate
interactions in the human gut. Their work was also a part of a
recent collaborative project with Agency for Science, Technology
and Research (A-STAR), Singapore, where their approach provided
insights into the metabolic underpinnings of how the gut recovers
following antibiotic treatment.
The algorithm is based on the popular computer science area called
network theory, where the interactions between different elements
define their associations. “Here, we systematically navigate
through the metabolic networks to identify the possible metabolites
that can be exchanged between the bacteria. We then define the
associations based on these metabolic exchanges,” Karthik Raman,
associate professor, Department of Biotechnology, IIT Madras,
said.
These metabolites define the kind of relationship between the
bacteria. The team devised a new metric called ‘Metabolic Support
Index (MSI)’, which helps to quantify the benefits that an organism
receives in a microbial community.
The research work has been published in Computational and
Structural Biotechnology Journal. The research team comprises Smita
Srivastava, Karthik Raman and Aarthi Ravikrishnan.

improving wave forecasts
Researchers at the Indian National Centre for Ocean Information
Services (INCOIS),
Hyderabad, have found a method of improving wave forecasts. They
have ascertained
that certain phases of boreal summer intra seasonal oscillation or
BSISO induce high-
wave activity in the northern Indian Ocean and Arabian Sea. The
finding will help to
improve wave forecasts in the Indian coastal region and help
mitigate the adverse
impacts of high waves such as coastal flooding and erosion. It will
also aid better
planning of sea navigation routes in the northern Indian Ocean
waters.
Boreal Summer Intra-Seasonal Oscillation (BSISO) is the movement of
convection
(heat) from the Indian Ocean to the western Pacific in roughly
every 10–50 days of
20
the monsoon season from June to September. BSISOs represent
monsoon’s ‘active’
and ‘break’ periods, in which weeks of heavy rainfall give way to
brilliant sunshine
before starting all over again. The active phase also enhances
monsoon winds and
hence the surface waves.
BSISOs represent monsoon’s ‘active’ and ‘break’ periods, in which

The team worked with data on Indian ocean waves such as their
height, period, and
surface winds over a span of 38 years from 1979-2017. By using
mathematical data
analysis models, the research team studied the relationship between
various phases of
BSISO and the height of waves in the Indian Ocean. They found that
waves induced
by active phases of BSISO are nearly 0.5 meters higher than those
which occur during
other phases of BSISO. The active phases of BSISO occur between
June to August
which are the monsoon summer months. “This finding has a great
significance in
developing seasonal and climate forecast service for waves and
coastal erosion for
India. Under the Deep Ocean Mission of the Ministry of Earth
Sciences, we will be
initiating work on this very soon”, said DrBalakrishna Nair,
Director of INCOIS,
Hyderabad, who led the study. The findings were published in a
recent issue of the
journal Scientific Reports.

for efficient
coastal and marine management”, he added. His team included

Shinier, robust and pinchpenny LEDs By Indus Scrolls Bureau -
August 9, 2020
Light-emitting diodes (LEDs) have replaced the ordinary bulbs and
they can
further reduce the energy needs on large scale. Researchers from
the Indian Institute of Technology (IIT), Guwahati and Imperial
College London, UK, have
developed a tailored ‘meta-grid’ of nanoparticles that could make
light-emitting diodes (LEDs) even brighter, energy-efficient and
durable. ‘Meta-grid’ or
‘metamaterial grid’ is a specifically patterned array (grid) of
nanoparticles acting as metamaterials, capable of exhibiting
extraordinary optical properties.
Over the years, a significant research drive towards this objective
is in exploring
new materials for LED-chip encapsulation, mostly by deploying
either higher refractive index glasses or epoxy materials
incorporated with filler powders or
nanoparticle-loaded-epoxy or engineered epoxy resins, etc. However,
these techniques either make the LED chips bulkier or their
fabrication becomes more challenging and less economically viable
for mass production.
To meet the goals the research team has developed a nanoparticle
‘meta-grid’, which can be placed at an appropriate location within
the epoxy casing of the
LEDs, for improving light output from LEDs. A ‘meta-grid’ is a
specially- designed, optimised, two-dimensional array of specific
nanoparticles, of size much smaller than the wavelength of
light.
While prescribing minimal changes to the manufacturing process, the
research
team has developed this novel scheme of boosting transmission of
light generated inside an LED chip across the LED-chip/encapsulant
interface. This is
achieved by reducing the Fresnel reflection loss at the
chip/encapsulant interface, within a fixed photon escape cone,
based on tuning the destructive
output over any narrow/broadband emission spectrum, besides
boosting LEDs’ lifetime by eliminating heating of the chip from
unwanted reflections within the chip.
Dr. Debabrata Sikdar, Assistant Professor, Department of
Electronics and Electrical Engineering, IIT Guwahati said, “In this
invention, the effects of the
‘meta-grid’ on the standard commercial LEDs, based on group III–V
materials are demonstrated. However, the proposed concept of
enhancing light
transmission from an emissive layer to its encapsulant casing can
be extended to other types of light emitting devices hosting an
emissive-layer/encapsulant
interface. Generally, our nanoparticle ‘meta-grid’ scheme for
enhanced light extraction could potentially cater to a wider range
of optical gadgets, not just semiconductor LEDs.”
Talking about their work, Prof. Sir John B. Pendry, Department of
Physics, Imperial College London, said, “The simplicity of the
proposed scheme and the
clear physics underpinning it should make it robust and, hopefully,
easily adaptable to the existing LED manufacturing process. It is
obvious that with larger light extraction efficiency, LEDs will
provide greater energy savings as well as longer lifetimes of the
devices”.
The research team includes Dr Debabrata Sikdar, Prof Sir John B.
Pendry and Prof Alexei A. Kornyshev from Imperial College, London.
The findings have been published in Light: Science &

cater to a wider range of optical gadgets, not just semiconductor
LEDs.”
Talking about their work, Prof. Sir John B. Pendry, Department of
Physics, Imperial College London, said, “The simplicity of the
proposed scheme and the clear physics underpinning it should make
it robust and, hopefully, easily adaptable to the existing LED
manufacturing process. It is obvious that with larger light
extraction efficiency, LEDs will provide greater energy savings as
well as longer lifetimes of the devices”. The research team
includes Dr. Debabrata Sikdar, Prof Sir John B. Pendry, and Prof
Alexei A. Kornyshev from Imperial College, London. The findings
have been published in Light: Science & Applications journal.

Department of Pharmaceuticals will come forward to support
CSIR-IICT in
developing and transferring indigenous technologies for some of
these materials
By India Science Wire | Published: 10th Aug 2020 6:16 pm
Hyderabad: In the wake of the novel coronavirus outbreak, the
pharmaceutical industries and
the academic institutions are more eager than ever to collaborate.
In an important
development, Indian Institute of Chemical Technology (IICT) and
Department of
Pharmaceuticals, Ministry of Chemicals and Fertilizers have joined
hands to embolden India’s
efforts of self-reliance in pharma sector.
The announcement came following an appeal of Dr P D Vaghela,
Secretary, Department of
Pharmaceuticals (DOP), Ministry of Chemicals and Fertilizers urging
CSIR-IICT to champion
industry-academia partnership, while speaking on the occasion of
the 77th Foundation day
celebration of IICT.
Dr Vaghela invited IICT help DOP to establish Centres of Excellence
in bulk-drug research in
three National Institute of Pharmaceutical Education and Research
(NIPER) institutes, identified
for the purpose. He also requested Council of Scientific and
Industrial Research (CSIR) and CSIR-
IICT in particular to play a dominant role in preparing a
comprehensive Research and
Development policy for the pharmaceutical sector.
Currently, critically important KSMs (Key Starting Materials) and
APIs (Active Pharma
Ingredients) are mostly imported. DOP will come forward to support
CSIR-IICT in developing
and transferring indigenous technologies for some of these
materials. Dr Vaghela emphasised
that the need of the hour is to reduce the dependence on imports of
critical chemicals, and
expects CSIR-IICT to take significant role in making India
self-reliant in pharmaceutical sector.
The department is planning to allot Rs 1000 crores to develop
pharma parks in various states.
The companies setting up their units in these parks will be
eligible for incentives from the state
and central governments. Dr Vaghela felt the need of seamless
procedures required in
providing skilled staff, scientists, academia-industry relationship
for a continuous research in
the country.
Such a process can make pharma products competitive and reduce the
dependence on imports.
“DOP will look upon Institutes like CSIR-IICT in helping the State
governments develop common
utilities like, Steam generation, analytical facilities, pilot
plants etc” said Dr Vaghela.
Dr Shekhar C. Mande, Director General, CSIR said that
industry-academia relationship is very
important and CSIR will extend all possible collaboration in making
India an ‘Atmanirbhar
Bharat’ by actively participating in R & D Programmes and in
building industry-academia
relationships.

found in Andaman and Nicobar Islands
These crabs help “clean up” the sea bottom by harvesting
decomposing plants and animals, thus
helping in detritus formation, nutrient recycling, and dynamics of
the marine ecosystem

The Andaman and Nicobar Islands have been found to be home to
different species of
deep-water Brachyuran crabs, a recent survey carried out by Center
for Marine Living
Resources Ecology (CMLRE) noted.
Brachyuran crabs bear immense ecological and economic significance.
They are not
only an important source of protein but also a rich source of
carbohydrates, lipids,
vitamins and minerals, helping the fisheries industry
flourish.
The deep-water survey, carried out with the help of Fisheries Ocean
Research Vehicle
Sagar Ratna, has revealed the presence of seventeen species of
Brachyuran crabs,
including three species which were recorded for the first time in
the area.
Most importantly, the CMLRE survey spotted the seventeen crab
species in newer
areas of the ocean. These crabs are ecologically important for
being both a predator
and prey in the marine food web.
Brachyuran crabs also play a key role in the deep-water ecosystem.
They help “clean
up” the sea bottom by harvesting decomposing plants and animals,
thus helping in
detritus formation, nutrient recycling, and dynamics of the
ecosystem. Crabs are also
used to cure different ailments like stomach ache, liver and lung
diseases, and heal
wounds, osteoporosis, epilepsy, and reproductive malfunction in
women, among others.
The research team, for the first time, found a rare porter crab
‘Homolochunia valdiviae
Doflein, 1904’, inhabiting a wide depth of 395-1000 metres in the
Northern Indian
Ocean, previously known only to be in the Western Indian and
Western Pacific Ocean
regions.
Another species of deep-water elbow crab ‘Dairoides seafdeci Takeda
and
Ananpongsuk’, 1991, which is endemic to the Andaman Sea, was found
for the first time
in the Indian Exclusive Economic Zone (EEZ) with a relatively
narrow depth range of
299–633 meters.
A third species of deep-water pebble crab ‘Parilia pattersoni PKL
Ng, Devi and AB
Kumar’, 2018, earlier found in western Bay of Bengal, got recorded
by the CMLRE
research team for the first time in both the Andaman Sea and
Arabian Sea.
The research team comprised Sherine Sonia Cubelio, VP Padate,
Narayanane
Saravanane, and Maruthadu Sudhakar of CMLRE, Ministry of Earth
Sciences, Cochin,
besides KM Amritha of Kerala University of Fisheries and Ocean
Studies (KUFOS) and
eminent carcinologist Professor PKL Ng of the National University
of Singapore.
The research paper is published in the Journal of Regional Studies
in Marine Science.

COVID-19 Virus Through Computational
Research Stash News Aug 12, 2020
Novel Coronavirus has devastated the whole world. Numerous research
groups are racing against
time to decode the COVID-19 virus, in order to find cures for the
catastrophic pandemic. A
research team from the Indian Institute of Technology (IIT), Mandi,
in collaboration with
researchers from Virginia Commonwealth University and the
University of South Florida, USA,
has used computational tools to understand an important part of the
viral proteome called
Intrinsically Disordered Protein Regions (IDPRs).
The COVID-19 virus essentially consists of the genetic molecule,
RNA, enclosed in an envelope
made of lipids and proteins. Once in the host, the virus overpasses
the host defense mechanisms
and inserts its RNA into the host cells. Then, the virus hijacks
the host cell machinery to use the
viral RNA for the production of viral proteins in a process called
‘translation’, and the infected
cell starts generating toxic viral proteins, which leads to various
conditions and symptoms. It is
known that proteins provide both structural and functional
characteristics to living things and
extraneous (viral) proteins can take over the functions of human
cells.
“In COVID-19, the RNA is translated first into proteins that
perform a wide range of functions.
Since protein functions depend both on ordered and disordered
regions, it is important to
understand the whole proteome considering both ordered and
disordered proteins”, explains Dr.
Rajanish Giri, Assistant Professor, School of Basic Sciences, IIT
Mandi. The set of proteins or
proteome comprises both ordered regions and disordered regions in
proteins.
“Intrinsically Disordered Proteins (IDPs), and IDPRs are gaining
attention in recent times
because they have been discovered to play vital roles in various
biological processes”, said Dr.
Giri.
The IDP and IDPRs have been strongly correlated with the virulence
of viruses. Deciphering
their structure and functions in COVID-19 can help find ways to
mitigate the effects of the
infection. Both the protein structure and non-structure are
fundamental things and their
knowledge is paramount to understand the virus pathogenesis. With
computational tools it’s
possible to investigate the propensities of the proteins and
regions, that may or may not form the
structure.
“We have investigated the disordered side of SARS-CoV-2 proteome
using a complementary set
of computational approaches to check the prevalence of IDPRs in its
proteins and to shed some
light on their disorder-related functions, besides their
disorder-based binding motifs, known as
molecular recognition features”, Observed Dr. Giri.
The studies have shown the crucial role of IDPRs in the maturation
of individual proteins. It is
found that many of these proteins contain disorder-based binding
motifs. “Since many
IDPs/IDPRs undergo structural changes upon association with their
physiological partners, our
study generates important grounds for better understanding of the
functionality of these proteins,
their interactions with other viral proteins, as well as
interaction with host proteins in different
physiological conditions”, Dr. Giri observed.
He further adds, “The process of rational drug design is currently
limited since it mostly ignores
the presence of intrinsic disorder in target proteins. The
understanding of the structure of these
regions in the COVID-19 proteome is valuable to structural
biologists involved in high
throughput and structure-based screening for drug
development”.
The IIT Mandi team has also compared IDPRs among the closely
related viruses, human SARS,
and bat SARS-like CoVs. Such comparisons aid a better understanding
of the sequence and
structural peculiarities of the evolution of the virus and its
virulence.
The IIT Mandi researchers plan to conduct more in-depth studies to
establish structure-function
relationships for a better understanding of the functioning of
SARS-CoV-2 proteins. ‘Currently,
we are also performing experiments to further investigate the
disordered proteins in SARS-CoV-
2’, Dr. Giri concluded.
The research team includes Dr. Rajanish Giri, Taniya Bhardwaj,
Meenakshi Shegane,
Bhuvaneshwari R. Gehi, Prateek Kumar, and Kundlik Gadhave from IIT
Mandi, Dr. Christopher
J. Oldfield, Virginia Commonwealth University and Dr. Vladimir N.
Uversky, University of
South Florida. The results have been published in the journal
Cellular and Molecular Life
Sciences. (ISW)
An App based science talent Hunt
VVM is an app based, science talent search examination conducted
online. The
students may register individually or through schools against
payment of a
registration fees of Rs. 100.
By India Science Wire | Published: 13th Aug 2020 5:20 pm
Hyderabad: While the fear of spread of novel Coronavirus has forced
formal
schools and colleges to operate virtually, Vijnana Bharati (VIBHA),
in collaboration
with Vigyan Prasar (VP) and National Council of Educational
Research and Training
(NCERT), has come up with a unique program in a virtual mode, for
science
popularization among school students from class VI to XI. The
program titled
“Vidharthi Vigyan Manthan (VVM)” is a national level program
conceptualised to
identify young bright minds with a scientific aptitude among the
students at
secondary level.
VVM is an app based, science talent search examination conducted
online. The
students may register individually or through schools against
payment of a
registration fees of Rs. 100. Four days before the date of exam,
the student will
receive an SMS and Email notification to download the latest App.
The download
must be done at least three days prior to the exam date.The exam
will be
conducted on windows and android platforms only. VVM App will be
available for
download (link will be enabled), post 25th November 2020.
Preliminary level
examination will be conducted on 29th and/or 30th November,
2020.
“The mandate of VVM matches with that of Vigyan Prasar (VP).
Creating interest
in science at school level through such a wide competition fosters
the scientific
awareness in a child. With this converging ideology, VP has always
felt that there
is a much bigger need of similar competition-based programs in
science” said Dr
Nakul Parashar, Director, VP.
48
Under this program various hands-on workshop and competitions will
be held to
make aware successful students about India’s contributions, from
traditional to
the modern world of science and technology. These competitions will
be helpful
in identifying students that can be taken to the State and National
level. The
bright students would be felicitated and visits would be organised
for the winners
to various research and development institutions in the country.
VVM will also
provide mentors for selected students to carry forward their
education in the field
of science.
On answering how such competitions make the students future ready,
Dr
Parashar observed that Indian science needs to be brought to the
fore and VVM
has a dedicated section that deals with it. “At the school level,
this helps a
youngster to know more about our Indian Science, its rich past and
how it has
come of age. With the introduction of Indian Science at an early
age through
competition like this, a greater awareness and interest for science
amongst
children is generated” he told.
Registration will be available only through online mode on VVM’s
website
https://www.vvm.org.in. from 01 August, 2020 to 30 September,
2020.

than ever: Study
The study also showed that the September of 2018 was the third
warmest on record
By India Science Wire Published: Wednesday 12 August 2020
A recent study from the National Centre for Polar and Ocean
Research (NCPOR) in
Goa has pointed out that Arctic sea ice is melting at an alarming
rate, especially
during the boreal or northern hemisphere summer.
The study, published in the journal Heliyon, highlighted the
increasing decline of the
Arctic sea ice due to climate change. It reported that September
sea ice declined to
its lowest extent of 4.71 million square kilometeres in 2018, its
lowest in the past four
decades.
The study to measure the extent of Arctic sea ice loss was led by
Avinash Kumar
and his team of scientists comprising Juhi Yadav and Rahul Mohan
from NCPOR.
“The minimum extent of seasonal sea ice for 2018 was recorded
between
September 19 and 23. Prior to September 19, 2018, sea ice extent
had declined at a
rate of nearly 14,000 square kilometres per day that was
significantly faster than in
most previous years,” Kumar observed.
The study also showed that the September of 2018 was the third
warmest on record,
with temperature differences of the air above the Arctic Ocean
(~3.5°C) to be slightly
higher than that of the Arctic land (~2.8°C).
The decline in sea ice can lead to accelerated global warming and
climate changes.
“The faster loss of sea-ice for the whole Arctic Ocean during
September
demonstrates that there are substantial variations in surface air
temperature and
there is a correspondence between the fluctuations in surface air
temperature in the
Arctic and global regions,” Kumar added.
The Arctic is warming twice as fast as the rest of the globe, a
phenomenon known
as arctic amplification. Arctic sea ice loss is attributed to
several factors such as
rising global temperatures. The study suggests that due to more
open seas in
winters, the growth of sea ice is delayed, leading to
disproportionate loss of sea ice
occurring during summer.
For the study, researchers obtained data of Arctic ice extent,
thickness, and volume
from 1979-2018 from globally-available satellite data and applied
modelling
techniques. They also studied its correlations with atmospheric and
surface
temperatures and sea pressure.
As a result, they were able to see how ice in the Arctic region has
changed over the
last four decades. It also helped them to predict the possible sea
ice scenario in the
coming years. The group is now planning to expand their work to
study how sea ice
melting and intrusion of warm ocean waters are related.

Pandua (R).The sketch figure

IITM).
(India Science Wire): Babu ChunderSikur Chatterjee, an Indian
scientist employed with the
Surveyor General of India during the British colonial era, was
likely the first person to
scientifically document a tornado’s path in 1865, claims a study
from the Indian Institute of
Tropical Meteorology (IITM), Pune. By carefully searching and
analysing papers about tornados,
Saumyendu De and Dr A K Sahai, scientists at IITM Pune, concluded
that Chatterjee’s paper is
the earliest record of a tornado’s dynamics in the history of
meteorology.
Chatterjee had published his findings in a journal named
Proceedings of the Asiatic Society of
Bengal, in a paper titled ‘Note on a whirlwind at Pundooah’. The
paper described tornado’s
dynamics in meticulous detail and was accompanied by a sketch that
mathematically depicted
the tornado’s scale,track androtation. “There is a legacy of
meteorological research in India. We
find that it is Chatterjee’s brilliance and nature’s assistance
that helped him decode tornado’s
60
scale and dynamics with such scientific rigor that his conclusions
are relevant even today, that
is, more than a century later”, said Saumyendu De.
At the time when Chatterjee published his paper, records of extreme
weather events in India
existed as eye witness accounts or entries in ships’ logbooks. This
remained the situation for
most of the nineteenth and early twentieth centuries. But
Chatterjee did it differently. He
quantitatively mapped the entire trail of tornado’s destruction. He
benefited from the rare
opportunity to observe tornado passing through a railway track
where there were conveniently
placed markers at predefined locations like railway line mileposts
and telegraph posts that
enabled him to observe and make clear measurements of tornado’s
direction, dynamics, and
path.
A tornado appears as a strong whirlwind, which is a rapidly
rotating column of air with a
suction spot at its centre that is in contact with both the Earth’s
surface and a thunderhead
cloud. It is generally accompanied by extreme weather such as heavy
downpours, hail storms,
and lightning. The tornado documented by Chatterjee had occurred on
5 May 1865 at 18:00
hours in Pandua, located in the Hooghly district of West Bengal.
Pundooah is a railway station in
Pandua area of Hooghly.
“It is interesting to establish the length of time for which
society has had an affinity for a given
subject. Our study provides a means by which one compares the
development of scientific
knowledge at different periods in time across the world”, observed
Dr Sahai.
Saumyendu De and Dr A K Sahai have published the evidence piece in
a recent issue of the
journal ‘Weather’ of the Royal Meteorological Society. IITM Pune is
under the Ministry of Earth
Sciences, Government of India. (India Science Wire)

A recent study from The National Center for Polar and Ocean
Research (NCPOR) has
revealed valuable insights on the functioning of major
biogeochemical cycles, by understanding
the chemical composition of lake waters in Antarctica, which play a
vital role in assessing the
solute dynamics.
Climate systems depend on marine biogeochemical processes that
produce organic compounds
in ocean waters, emissions from the ocean, marine aerosol
formation, and transition of the
subsets of aerosol populations to cloud droplets and ice
crystals.
Marine aerosols are important drivers of climate that affect the
planetary radiation balance
directly by scattering and absorbing direct sunlight, and
indirectly by modifying cloud
microphysical properties. The primary aerosol components are
produced from the interaction of
wind stress at the sea surface that results in the production of
sea spray. The sea spray is enriched
with inorganic sea salt and organic matter that interact with the
freshwater lacustrine systems and
alters the lake biogeochemistry.
Marine aerosols are important drivers of climate that affect the
planetary radiation
balance directly by scattering and absorbing direct sunlight, and
indirectly by
modifying cloud microphysical properties.
NCPOR scientists revealed that rock-water interactions are the
primary source for dissolved
metals in lake water, followed by sea spray and long-distance
atmospheric transport in the form
of aeolian dust. Mineral groups such as sulfate, carbonate, metal
oxides, and hydroxides are
responsible for the dissolution of metal complexes in lake water.
In addition, lakes falling within
a micro basin have shown to increase concentrations of major ions
due to sea spray cycling
through catchment effect.
NCPOR also found that rock dominance, precipitation and
evaporation/sea spray via marine
aerosols are important hydrogeochemical processes that control the
water composition of the
lacustrine systems in Antarctica. Silicate weathering, evaporation
and carbonate dissolution also
contribute ionic loads to lake water. Increased knowledge of
rock-water interaction would help in
better understanding of the hydrogeochemical characteristics of
lakes that can help in effective
management and utilization of lake water resources too.
The ions are associated with silicate rock forming minerals and
interact with melt water, thereby
affecting the overall aquatic ecosystem of the lakes. Similarly,
trace metals are associated with
major elements and they play an important role in the carbon and
nitrogen cycles.

Sathish Mohan Botsa,
Soniya Dessai, Mamta Mestry and Tara Da Lima Leitao of NCPOR,

Sewage holds the key to measure the actual extent of COVID-19
spread
Center of Scientific and Industrial Research (CSIR) institutions
Centre for Cellular and
Molecular Biology (CCMB) and Indian Institute of Chemical
Technology (IICT) in a joint
study have harvested the sewage samples to estimate the number of
potentially infected
individuals in the city of Hyderabad
By BioVoice News Desk - August 24, 2020
New Delhi: Various studies have demonstrated that faeces can
harbour SARS-CoV-2. Center of Scientific and Industrial Research
(CSIR) institutions Centre for Cellular and Molecular Biology
(CCMB) and Indian Institute of Chemical Technology (IICT) in a
joint study have harvested the sewage samples to estimate the
number of potentially infected individuals in the city of
Hyderabad.
The novel coronavirus (SARS-CoV-2) in sewage samples is found to be
non-infectious, thus it can be easily taken for epidemiological
studies. Estimating the spread is very important in identifying the
affected areas and controlling the pandemic. Since an infected
person sheds viral material in faecal samples for up to ~35 days,
these studies will provide an overall estimate of the situation in
a window of one month.
To carry out the studies sewage samples from major Sewage Treatment
Plants (STPs) were processed for detecting presence of SARS-CoV-2
viral RNA. While viral RNA is detectable in the inlet samples, the
outlet (after treatment) samples of STP were largely clean (free
from viral RNA)in this regard, indicating efficient treatment
practices at STP.
Of the 1800 million litres water used daily in Hyderabad, 40% is
processed at different STPs.This study covers about 80% of the STPs
in Hyderabad revealed that there are around 2 lakh people who are
shedding viral materials. Since only 40% of the Hyderabad sewage
reaches STPs, this data can be used to extrapolate the overall
number of potentially infected people, which turned out to be
approximately 6lakhs, that is, around 6% of the city’s population.
The number includes symptomatic, asymptomatic, and also recently
recovered individuals in a time window of about 35 days. A
conservative estimate of the number of active cases who are
shedding the virus may be around 2 lakhs.
“Our finding clearly indicates that a large proportion of the
affected individuals are asymptomatic and did not need
hospitalization. This is also in agreement with the observation
that hospitalization rush or mortality is way lower than otherwise
expected with such a large infection rates at a given time. It
explains why our healthcare system has been able to handle
reasonably well the situation during the pandemic. Such studies if
carried out in coordination with civic bodies to identify the
hotspots in the city and monitor the dynamics of the infection rate
can assist the system in taking necessary measures”, explained, Dr
Rakesh Mishra, Director, CCMB.
The findings are posted on preprint server, MedRxiv, which is yet
to be peer reviewed. All the experiments were conducted at the
CSIR-CCMB COVID-19 testing facility and the teams included
HemalathaManupati, KopperiHarishankar and S.Venkata Mohan from
CSIR-IICT and Uday Kiran, C.G. Gokulan, Santosh Kumar Kuncha and
Rakesh K Mishra from CSIR-CCMB.

The Department of Biotechnology (DBT) is committed for development
of
affordable and effective biopharmaceutical products and services.
DBT’s Biotechnology Industry Research Assistance Council
(DBT-BIRAC) is
implementing the Department’s Industry-Academia Collaborative
Mission to accelerate discovery research to early development for
biopharmaceuticals.
The mission was approved by the Union Cabinet, with a total cost
US$ 250 million, with 50% co-funding by the World Bank.
Also known as the National Biopharma Mission (NBM), this program
supports establishment of Technology Transfer Offices (TTOs) that
are
critical for value realization of biotech innovation for inclusive
growth. The TTOs facilitate translation of publicly funded research
results into products
and their delivery to markets by licensing innovation to
enterprises. They also facilitate inter-institutional
collaborations by collectively engaging them
in creating market presence for their innovations.
70
Indian research results have significant potential to transform
markets and
this under-realized prospect is addressed by providing strong
impetus to the technology transfer process with TTOs created and
managed by
professionals having skills in technology management. Technology
transfer strengthening is a long-time commitment and for the first
time the NBM has
committed significant resources for creation of technology transfer
office framework and strengthening technology transfer
professionals for the
advancement of publicly funded research.
The TTOs identify inventions, protect them with due assessment of
patentability, shape commercialization strategy and identify
enterprises for
licensing innovations for accelerated delivery to markets. With a
vibrant
start-up ecosystem emerging in the country, they have potential to
create and nurture spinouts too that can support the inventors to
create their own
enterprises for commercialization.
Five TTOs have already been established across the country with a
view to strengthen the technology transfer capacity, evenly in
India. These are
located at: the National Biopharma Mission (NBM), this program

Two other TTOs are in the process of being created within the aegis
of the Mission. The TTOs have necessary digital tools for patent
analysis and
management, licensing transactions management and
post-license

monitoring. The new ones will bring under their fold more
institutions that
need professional support for advancing their research results to
markets.
The TTOs established with NBM support have made significant
progress in the recent past. TECHEX.IN is a Technology Transfer Hub
operated by EDC
at Venture Center, Pune, that aims to help technology developers
and technology commercialization entities find each other, forge
partnerships
and advance the technology closer to the market in a win-win
partnership.
It has recently conducted many important trainings: an online
session on
‘Negotiation Techniques for Technology Entrepreneurs and Innovation
Managers’ was conducted on 30th May 2020, another on ‘COVID-19
drug
candidates: Understanding patent landscapes and navigating patent
barriers’ on 8th June 2020 and a third online training programme on
‘Understanding
and Negotiating Non-disclosure Agreements (NDAs) and Material
Transfer Agreements (MTAs)’on 13th June 2020. Further training
sessions on
‘Ideating and evaluating commercializable R&D: Thinking
frameworks and examples’ and ‘basics of IP and filing of patents’
were conducted on 17th
July and 8th Aug 2020 respectively.
IKP-PRIME, at IKP, Hyderabad also conducted online training
sessions on ‘an
insight into IP management’ and ‘scope of patenting AI inventions’
on 24th and 31st July 2020 respectively. ‘Need for IP protection’
and ‘Creating value

The world will need a significantly increased clean energy supply
in the future. Solar energy is a viable solution but there are
certain limitations. Solar energy conversion to electricity and its
storage at a low cost is an integral part of renewable energy
research.
Indian Institute of Technology Madras (IIT Madras) researchers have
discovered a new material to effectively split water into Hydrogen
and Oxygen using solar power. This research is expected to create a
renewed interest in the Solar fuels’ domain, for its scope of
conversion and storage in a single system. The method can
significantly reduce the cost per kilowatt-hour (kWh) of solar
energy.

Touching upon the applied aspects of the research, Dr. Aravind
Kumar Chandiran, Assistant Professor, Department of Chemical
Engineering, IIT Madras said, “Storing solar energy in batteries is
an expensive business for large scale implementation. A single
photoelectrochemical (PEC) system that can harness and store solar
energy in the form of chemical fuels can potentially reduce the
cost per kWh of energy.
Ideally, seawater splitting using PEC to generate clean hydrogen
should be serious research, if India should remain committed to
green energy and avoid potential consequences of continued carbon
emission. In our recent work, we attempted to make a first
successful demonstration of water splitting using the best
photovoltaic material.”

Group
In 2009, the research community employed a new class of
semiconducting materials, called ‘halide perovskites’ with formula
CH3NH3PbI3, for solution processible solar cells. In less than a
decade the efficiency of these devices improved from 3% to over
25%. For comparison, the conventional silicon-based solar cells
took nearly three decades to reach
74
25%, since the establishment of certification standards by the
National Renewable Energy Laboratory.
This fast growth of the perovskite-based solar cells, however, is
significantly limited for commercial scale-up due to the presence
of the toxic lead and instability of these devices in ambient
conditions. The entire device fabrication has to be carried out in
the inert atmosphere, literally under zero oxygen and water to
avoid degradation, and they have to be encapsulated to avoid
ambient exposure.
To take this technology up for commercialization, efforts from
research groups across the world have been focused on non-lead and
ambient stable halide perovskite absorbers. Several hundreds of
research papers have been published on improving the robustness of
this material in oxygen and humid conditions, by selectively tuning
the constituent atoms. However, only partial ambient stability is
achieved and these state-of-the-art materials still decompose
instantly when they come in contact with water.
Another team member of the research group Muhammed Hamdan, while
investigating materials for solar cells, discovered a ‘halide
perovskite’ (Cs2PtI6), which completely absorbs the entire visible
light and remains extremely stable in ambient. This material is
also found to be stable in strong acids and bases.
Mr. Hamdan combined solar energy conversion and storage in the form
of chemical fuels by utilizing this material’s record stability.
Using sunlight, and with a photoelectrochemical device made with
Cs2PtI6, the team was able to successfully split water into
hydrogen and oxygen.
The generation of solar fuels is not only restricted to water
splitting to generate hydrogen fuel, but the perovskite
semiconductors can also be used in carbon dioxide conversion to get
useful hydrocarbon fuels. In the long run, the design principles of
this material, platinum in Cs2PtI6, can be replaced with other
low-cost transition elements to reduce the costs further.
Dr.Chandiran observed, “To date, in the world of halide
perovskites, this is the only material that shows such
extraordinary stability in a harsh environment.” The paper co-
authored by Dr. Aravind Kumar Chandiran and research scholar
Muhammed Hamdan has been published in the journal Angewandte
