Thank you.

- Thank you.

I came to Australia to study the deadliest animal in the world.
6
Now there may be some Australian audience members thinking, "Ruth!
7
Science has finally recognized the importance of the drop bears.
8
But I'm not studying drop bears, because around the world, by transmitting diseases like malaria and dengue fever, Mosquitoes kill more than a million people every year,
9
making them the deadliest animal on the planet.
10
Now in Australia, the most common mosquito -borne disease is Ross River virus, and it occurs at high rates in some areas but not others.
11
My question is why?
12
What is it about certain areas that makes them breed disease?
13
If we can understand the environmental factors that contribute to disease transmission, then we can alter the environment or target our control efforts prevent human infections.
14
But to answer that question, I had to find out where the infected mosquitoes were in South Australia.
15
And traditionally, testing mosquitoes for virus has always been difficult.
16
So I used a new technique.
17
It takes these cards, which are embedded with virus -preserving chemicals, and coats them in honey.
18
Mosquitoes will come to feed on the honey, and in the process, spit virus onto the card, where it can later be detected.
19
Now, no one had ever used this technique in a broad -scale virus survey before, so I had to adapt it.
20
I developed new traps.
21
and set them at over 100 field sites across South Australia.
22
and I captured over 20 ,000 hungry mosquitoes
23
and let them feed on the card for a week before testing the cards for a virus.
24
Now you may not think that these traps look very impressive, But science doesn't have to be beautiful.
25
It has to be effective.
26
And these traps are proving to be our most sensitive method of detecting infected mosquitoes.
27
I found three types of infection.
28
Ross River virus, Barma Forest virus, and Stratford virus, which has never before been found in South Australia.
29
I now have the virus data I need to conduct my analysis.
30
and I'm collecting publicly available data about the environment surrounding my traps.
31
like the density of human housing, the biodiversity of mammals, and the ratio of green space to buildings.
32
to see if any of those environmental factors can link These virus hotspots that I've shown here, But the most exciting part of my research so far has been the success of this method.
33
Public health officials in Victoria, Queensland, and Western Australia have been in contact with us about implementing this technique for their surveillance next year.
34
And I developed these traps in a tight budget.
35
I used recycled milk cartons, pantyhose, and paperclips to make the traps.
36
Each trap costs less than a dollar and can be reused for the whole season.
37
That was important to me because the majority of mosquito -borne disease risk happens in economically impoverished countries.
38
In India, for example, where about a quarter of the population lives on a dollar a day, There are 33 million cases of dengue infection every year,
39
With my low budget virus surveillance and spatial analysis method, I can help any country, regardless of resources, find out where their deadliest animals occur,
40
why they're there, and how we can stop them from infecting humans.
41
Thanks.
42
Thank you.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
