Determining the sex of human remains – using tooth enamel

Scientists at the University of Brighton have discovered a new method of determining the sex of human remains – by testing tooth enamel. DNA sequencing is currently the most common method but this can be expensive, time-consuming, and often depends on finding a good quality sample. The new method is quicker, cheaper, and uses tooth enamel, the most durable human body tissue and the hardest tissue in the human body. It survives burial well, even when the rest of the skeleton or DNA has decayed.

The breakthrough has the potential to improve studies of archaeological finds and medical and forensic science. Researchers have tested the method on the remains of seven adults from the late 19th Century as well as male and female pairs from three archaeological sites ranging from 5,700 years ago to the 16th Century in the UK. In each case, the method successfully determined the sex, as confirmed by comparison with coffin plates or standard bone analyses.

The research has been carried out by Dr Nicolas Stewart, senior lecturer in the University’s School of Pharmacy and Biomolecular Sciences, with colleagues at Durham University and the University of São Paulo in Brazil.

Why treating stress could help beat cancer

The stress of being told you have breast cancer may be reducing the potency of drugs used to treat the disease, according to new research by the University of Brighton.

Early trials show stress-relieving medications may increase the efficacy of chemotherapy and by doing so, improve recovery. Managing stress and anxiety at an early stage, researchers say, could become routine.

Dr Melanie Flint

Dr Melanie Flint, Reader in Cancer Biology at the University of Brighton’s School of Pharmacy and Biomolecular Sciences, has been studying the impact stress hormones have on patients, and the effect chronic psychological stress has on disease progression, as well as response to drug treatment. Dr Flint said: “Stress hormones are highly potent and can interact with almost every cell in the body including normal, cancer and immune cells.”

Her research has shown that DNA can be damaged as a result of the interaction between our cells and stress hormones, leading to cell transformation: “A diagnosis of breast cancer is a cause of a great deal of stress, which in itself, is a significant reason for stress management to be considered early on.”

Melanie is part of a team of scientists at the University of Brighton researching breast cancer. Dr Flint collaborates with Professor Dame Lesley Fallowfield, Professor of Psycho-Oncology, who will be speaking at the British Science Festival on the 5 September, in an event titled, ‘Risk and uncertainty in breast cancer treatment’.

Open Consent: Genetics and the loss of anonymity

Professor Colin Smith, Professor of Functional Genomics, is the first person to donate his complete genome sequence under ‘open consent’ in the UK – waiving any rights to anonymity.

Join the discussion with Colin at the British Science Festival on the 8 September to understand the reasons for his decision, and why this approach will ultimately benefit the public if more people follow suit.

Location: Brighton City, Old Courtroom theatre

Duration: 17:00 – 18:00

Date: Friday 8 September 2017

BBC Springwatch on garden animals

University of Brighton mammalian biologist is calling on the public for ‘animal stories from the garden’ for research and a special feature for BBC Two’s forthcoming Springwatch series.

Dr Dawn Scott and her team are studying interactions between foxes, hedgehogs, badgers, cats and dogs in the presence or absence of food in people’s gardens.

Dr Scott, Principal Lecturer in the university’s School of Pharmacy and Biomolecular Sciences, said: “Many people support wildlife in their gardens by providing food for them. However, we don’t yet fully understand how providing food can affect the interactions between wildlife.

“It is not always known what animals actually end up eating this extra food or if the animals compete to get access to it. Foxes and hedgehogs have been seen to feed from the same bowl but we have also seen animals come into conflict over the food provided.

“The project will be focused on interactions between foxes, badgers and hedgehogs, but we are also interested in interactions between the same species, i.e. fox and another fox, and also between pets.”

Findings from the research will feature in BBCs Two’s Springwatch which is scheduled to air from 29 May to 15 June.
