This document summarizes efforts to reduce postharvest feed losses and improve feed utilization in smallholder systems in Ethiopia. Methods included training farmers in conservation practices and feed formulation. Improved feed troughs and sheds were constructed and demonstrated, reducing feed waste by over 30% and improving feed quality. Analysis found the costs of the troughs and sheds could be recovered within 6 months and 2-3 years, respectively. Over 140 troughs were subsequently scaled up with partners. Challenges to wider adoption included the need for locally suitable materials and designs.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Introduction
Postharvest feed loses and poor utilization practices contribute to
feed scarcity and poor livestock nutrition in the smallholder system.
Simple and affordable technologies and skills can considerably
minimize wastage of feeds during storage and optimize utilization of
available feed resources.
Results/Achievements
Method/Approaches
• Training and awareness creation on feed conservation practices.
• Construction and demonstration of improved feed troughs and feed
sheds.
• Training on feed formulation to optimize quality and efficiency.
• Data collection on the benefits of introduced technologies against
traditional practices.
• Field days and exchange visits.
• Capacity building of local stakeholders to provide service for their
communities.
• Feed wastage considerably reduced (>30%) due to the use of
improved feed troughs and storage sheds (Figure 1).
• Quality deterioration of straw, stover and hay during storage
avoided due to improved feed sheds.
• Minimal fungal contamination on stored feeds ensured reduced
health risk on farmers who handle feeds and feeding.
• Labor demand for feeding reduced (up to 20%) due to feed troughs.
• Positive effect on women and youth due to reduced demand for
labor.
• Analysis indicated the cost incurred on feed troughs can be
recovered within 6 months while that of feed sheds with 2-3 years
(Figure 2).
• The technologies enabled farmers to mix different feed ingredients
on feed troughs and feed a better quality diet.
• Improved feed troughs contributed to an efficient cut-and-carry
feeding system with cultivated forages and other collected feeds.
• Interest created among development partners to scale the
technologies.
• A total of 147 feed troughs scaled in 2017 and 2018 through
development partnerships.
• Train key resource persons in scaling woredas
to facilitate and support the construction of
improved feed troughs and sheds.
• Work with TAAT project and others partners to
mobilize resources for scaling.
• In-depth analysis of positive effects/gains on the
different SI domains.
Plan for 2019
• The modest level of investment at household level
and the skills required to construct are challenges
for wider adoption of the technologies.
• Use of locally available materials and modifying
the prototypes to suit individual farmers will be
important for scaling.
The Africa Research In Sustainable Intensification for the Next Generation (Africa RISING) program comprises three research-for-
development projects supported by the United States Agency for International Development as part of the U.S. government’s Feed the
Future initiative.
Through action research and development partnerships, Africa RISING will create opportunities for smallholder farm households to move out
of hunger and poverty through sustainably intensified farming systems that improve food, nutrition, and income security, particularly for
women and children, and conserve or enhance the natural resource base.
The three projects are led by the International Institute of Tropical Agriculture (in West Africa and East and Southern Africa) and the
International Livestock Research Institute (in the Ethiopian Highlands). The International Food Policy Research Institute leads an
associated project on monitoring, evaluation and impact assessment.
