Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

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.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

NAAC Accredited ‘A’ Grade
2. Family- Lamiaceae
Lamiaceae, formerly called Labiatae, the mint family
of flowering plants, with 236 genera and more than
7,000 species, the largest family of the order Lamiales.
Lamiaceae is distributed nearly worldwide, and many
species are cultivated for their fragrant leaves and
attractive flowers. The family is particularly important
to humans for herb plants useful for flavour, fragrance,
or medicinal properties.
3. Most members of the family are perennial or annual herbs
with square stems, though some species are woody shrubs or
subshrubs. The leaves are typically simple and oppositely
arranged; most are fragrant and contain volatile oils.
The flowers are usually arranged in clusters and feature two-
lipped, open-mouthed, tubular corollas (united petals) with
five-lobed bell-like calyxes (united sepals). The fruit is
commonly a dry nutlet.
Best known for its sharp fragrance is rosemary (Rosmarinus
officinalis), a Mediterranean species. Also Mediterranean
is lavender (Lavandula officinalis), with fragrant blue to
lavender flowers in leafless spikes.
5. Primitive characters:
1. Some members are perennial
shrubs.
2. Leaves simple.
3. Flowers hermaphrodite,
hypogynous, coloured and
scented.
4. Pollination by insects.
Advanced characters:
1. Plants mostly herbaceous.
2. Leaves exstipulate, opposite or whorled.
3. Flowers in distinct inflorescence.
4. Flowers zygomorphic and in some
unisexual (Iboza).
5. Calyx gamosepalous and bilabiate.
6. Corolla gamopetalous and bilabiate.
7. Stamens epipetalous and reduced to 2.
8. Gynoecium bicarpellary, syncarpous,
axile placentation.
9. One ovule per loculus.
10. Fruit simple.
11. Seeds non-endospermic.
8. Characters of Lamiaceae:
Sweet aromatic smell due to essential oils present in sessile
glandular hairs; stem rectangular in cross section, leaves
opposite decussate rarely alternate, simple, exstipulate with
hairs; inflorescence verticillaster; flowers zygomorphic,
hermaphrodite, hypogynous, bracteate; calyx gamosepalous,
persistent; corolla bilabiate; stamens 4 epipetalous,
didynamous; gynoecium 2 four celled by false septum,
syncarpous, axile placentation, gynobasic style, seated on
lobed disc; fruit schizocarpic carcerulus.
9. A. Vegetative characters:
Habit:
Plants are mostly aromatic herbs or shrubs (Leonotis, Pogostemon). Tree
habit is found in the Brazilian genus Hyptis and climbing habit in
American species of Scutellaria.
Root:
Tap, branched, rarely adventitious (Mentha).
10. Stem:
Aerial, herbaceous, rarely woody, erect or prostrate,
quadrangular, hairy, branched, solid or hollow, sometimes
underground suckers (Mentha).
12. B. Floral characters:
Inflorescence:
Very commonly verticillaster consisting of a pair of condensed dichasial
cymes at each node; often the verticillasters are grouped together in a
thyrsus form; rarely solitary (Scutellaria).
14. Calyx:
Sepals 5, gamosepalous, bilabiate (Salvia, Thymus) campanulate
(Teucrium), persistent, valvate or imbricate aestivation. When a bilabiate
calyx is present the arrangement of the sepals may be (1/4) as in Ocimum or
(2/3) as in Calamintha.
15. Corolla:
The corolla possesses a tubular base which widens towards the mouth. Petals generally 5, gamopetalous
and the five teeth are sub-equal and mostly bilabiate. In Mentha a four lobed corolla arises due to the
fusion of two upper teeth. When a distinct bilabiate condition is found the arrangement of the petals
may be gamopetalous 2/3 i.e. two petals in the posterior upper lip and three in the anterior lower lip
(Salvia, Nepeta, Leucas etc.).
In Ocimum, Coleus, Plectranthus etc. the petals arrangement is gamopetalous 4/1 i.e. four petals in the
posterior upper lip and only one petal in the anterior lower lip. In extreme cases the arrangement may
be gamopetalous 0/5 i.e. all the five petals forming the lower lip so that the corolla becomes one lipped.
Aestivation in the petals is valvate or imbricate.
16. Androecium:
Typically only 4 stamens, didynamous (2+2) and posterior stamen is reduced or
represented by a staminode; in Calamintha only two perfect stamens are found, two are
imperfect and the fifth reduced. In Salvia only two stamens on the anterior side are
found; they are characterised by peculiarly long connectives which help in insect
pollination stamens generally introrse and dithecous.
17.
18. Gynoecium:
Bicarpellary, syncarpous, superior, situated on hypogynous honey secreting disc;
bilocular becomes tetralocular by the formation of false septum; axile placentation, one
ovule in each loculus; style gynobasic (arising from the base of the ovary), stigma
bilobed. The gynoecium character is thus uniform without any variation.
22. Economic Importance of Lamiaceae:
1. Food:
Tubers of Stachys sieboldi are edible. Leaves of Mentha viridis, Ocimum basilicum,
Melissa officinalis etc. are used as condiments.
2. Medicinal:
Many plants of this family are used in medicines. Ajuga bracteosa, Leucas cephalotes
are used in fever. Mentha piperata and Thymus serphyllum give Menthol and Thymol
respectively, which are extensively used in medicines. Leaves of Ocimum kilimandus
charicum give camphor.
Ocimum sanctum and other species of Ocimum are used in various ailments.
3. Ornamental:
Several species of Salvia, Coleus, Ajuga, Leonotis, Dracocephalum, Thymus, Lavandula
etc. are cultivated in gardens for ornamental purposes.
4. Perfumes:
Aromatic oil is extracted from Thymus, Lavandula (Lavender oil), Rosmarinus
(Rosemary oil), Calamintha, Pogostemon etc.
5. Dye:
Fruits of Lycopus europaeus yield red dye.
