Our winner in the Science Gingerbread Competition

With her inspired creation showing circulating tumour DNA, Roxana Halstead, from REACH child cancer, Christchurch, NZ, won our Science Gingerbread competition.

So, we may not have a lot of contestants, but we still had a worthy winner in our Science Gingerbread competition. Here Roxana Halstead describes her gingerbred in closer detail.

“This is to illustrate the circulating tumour DNA that is floating around the blood stream, starting from the tumour ​and the gathering of DNA with a syringe and plasma sample in a test pot.”

“We [at REACH child cancer] are backing Professor Guilford at Otago University and funding his child cancer research, enabling researchers to monitor treatment response by tracking the mutations specific to a child’s tumour. ctDNA can be used to improve outcomes for those children already diagnosed with cancer. Based upon a normal blood sample, ctDNA can give a window into the progress of the tumour treatment. If a tumour is not responding to a treatment, ctDNA will show this faster than current techniques.

I’d like to point out i’m not a baker and it’s obviously a talent I’m lacking in the icing department! This wonderful creation was made in a caravan kitchen with my two year old creating havoc so to actually get a end result is a Christmas miracle! ”

We say congratulations to Roxana and will send her a Kindle ebook!


Dorota Paczesniak, Saskatoon, Canada: Seed development

Seed development #gingerbreadscience. The ovule (part of the flower containing female reproductive cells) contains a fertilized egg. Initial cell divisions establish embryo polarity, i.e. where the shoot and root will be, later the cotyledons (embryonic leaves) become visible. The embryo grows, supported by nutrients in the surrounding endosperm tissue. The development of the embryo is arrested inside the seed until external conditions enable germination and growth of a new plant.”

Erik Bergman, Lund, Sweden: f(x)=log x … sort of

“It should be f(x)=log x, but as the y axis became a little crooked it looks more like an inverted exponential equation.”
