Experiment with colorimetric gold nanosensorsNANOYOU
With this experiment you will discover the properties of gold at the nanoscale.
Gold (Au, atomic number 79) is the most malleable and ductile metal of all; it can be beaten to very thin sheets of material and rolled or bent as desired. This has been known and done for centuries.
In this experiment you will investigate nanoparticles of gold or nano-gold! The properties of nano-gold are very different and it all has to do with the size of the nanoparticles.
To download the protocol of the experiment and background information, as well as watching videos on how to perform it, visit: www.nanoyou.eu
Translations to several languages are also availabe in the NANOYOU website.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Focus on climate change
1. Changing ocean temperatures
2 - 4oC (3.6 - 7.2oF) global average increase by year
2100
2. Changing sea level
1.5 – 10 mm/year (0.06 – 0.4 inches/year) global
average increase to year 2100
3. Changing ocean pH
Average surface ocean pH decrease from 8.2 to 7.8
by year 2100
3. Conditions preferred by corals
• Temperature: 23-25°C;
• Light: for photosynthesis;
• Salinity required;
• Clean, clear water, sediment free;
• Well oxygenated water produced by
strong wave action
5. Types of Reefs
• Fringing reef – reef that is directly attached to a
shore or borders it with an intervening shallow
channel or lagoon.
• Barrier reef – reef separated from a mainland or
island shore by a deep lagoon.
• Atoll reef – a more or less circular or continuous
barrier reef extending all the way around a lagoon
without a central island.
8. Types of Corals
Hard corals (hermatypic): secrete a
limestone (CaCO3) exoskeleton around
itself as protection. This exoskeleton
remains even after the organism dies.
Soft corals (ahermatypic): tree-like and
flexible with a skeleton within their bodies
giving them shape but allowing movement
with the waves
10. Basic structure
z • Polyps = basis of life on reef.
• Produce calcium carbonate
skeleton as they grow.
• Polyp growth = symbiotic
relationship between the
coral animal and
zooxanthellae (algae).
• Zooxanthellae
photosynthesize and give
sugars and fats to polyp.
Veron (1986)
12. • Corals feed on zooplankton
• Tentacles help capture food
• Tentacles contain stinging cells
13. Symbiotic relationship with
zooxanthellae
Algae in the coral polyp
produce oxygen and
organic products for the
polyp
Coral polyps produce
carbon dioxide for the
algae and give protection
14. Reproduction
Corals reproduce either asexually by budding or by
sexually releasing gametes (sperm and eggs).
Sexual reproduction Asexual reproduction
Fertilization can occur within Budding occurs when a new
a coral known as “brooding” zygote grows onto another one
or outside of a coral known and remains attached,
as “broadcasting” separating only when mature.

19. Study Objectives
• Coral metabolism and calcification due to:
Light acclimation
• What response variables to measure (3 things):
1. Oxygen
2. pH
3. Alkalinity
• Things to vary (i.e.; when/where would these be different?):
1. Day/Night
2. Depth
• Hypotheses:
1. Calcification rates higher during the day than at night.
2. Shallower coral have higher maximum photosynthesis
but lower pigment concentration than deeper corals.
23. Methods
• The deep water colonies were carried inside
black bags to the experiment site (~5 m depth)
• We placed the colonies at a light level of the
origin growth place.

30. Summary
• Photosynthesis and calcification are light
dependent
• Photo-acclimation of endosymbiotic algae with
depth
– Pigment Concentration
– Maximum Photosynthetic Rate
– Respiration
• Light enhances calcification, calcification rates:
– Diel Cycle - Night vs. Day
– Depth - Deep vs. Shallow
31. Corals in the Future
Given what we learned in this study, how do
you think coral calcification might be
affected by:
1. increasing temperature?
2. sea level rise?
3. decreasing surface ocean pH?
