I love interaction and scientific dicussion. Never be afraid to ask me questions. I may not have the answer, but I'll be damned if I haven't learned how to do a good, quick Google Scholar search to find out.
In addition I like to look at non-science related cute animal pictures, art and funny comics too :)
Hope you enjoy my blog but please, feel free to leave suggestions for improvement!
A sensor that measures the amount of active antibodies in the blood stream is paving the way for personalised treatments for bacterial diseases, perhaps spelling the end of the superbug era.
Researchers have developed a new method involving the use of nano-sized levers as sensors to rapidly measure the level of antibiotic molecules in the blood as well as how effective the antibiotic is at dealing with the bacteria. This could pave the way for personalised treatment of bacterial diseases.
“Some of our most effective antibiotics are like termites eating away at the walls of a wooden house – they attack bacterial cell walls so they eventually collapse,” said Professor Matt Cooper, from The University of Queensland’s Institute for Molecular Bioscience.
“But competing molecules in the blood can bind to antibiotics and prevent them from working, meaning there are less molecules free to exert force on bacterial cell walls.
“The sensor we developed, one billionth of a metre in size, can detect the bending that occurs in a cell wall when it is assaulted by antibiotics. The sensor enables us to measure how many antibiotic molecules are free in the blood to attack bacteria and treat the infection based upon how much force they exert onto the wall.”

The history of DST:
Hudson was born in England and then moved to New Zealand when he was 16. His insect collection is housed in the Museum of New Zealand Te Papa Tongarewa.
Hudson published his first paper at the age of 14… ahem, start working on those manuscripts, entomologists.

:O who was the cadaver?!?!?!
The cadavers were individuals aged 70+ who died of natural causes and were part of the body donation program
T’was a very strong, existential experience.
Alas, I was not the fainter of the group (though I was feeling a bit light headed).
Points of interest included seeing how small and fragile the pancreas, thymus and appendix are (the latter looks like a frog leg), how rock hard the heart, uterus and liver become and how undigested and preserved food feels like solidified clay lumps in the intestines.
I’m excited to get into the real nitty gritty of human biology over the next several weeks.
Yay anatomy :)
