District nurse sought following fatal Rotherham collision

An appeal for witnesses, including a woman thought to be a district nurse, has been launched following a fatal collision in South Yorkshire earlier this year.

Carr Lane

A black Honda motorbike and a grey Nissan Navara pick-up truck collided in the village of Thrybergh, near Rotherham, at about 15:50 on Wednesday 24 June, say police.

The motorbike was being ridden along Carr Lane in the direction of Kilnhurst and the Nissan was travelling in the opposite direction when the two collided.

The 25-year-old bike rider suffered serious head injuries and died in hospital the next day.

The incident is still under investigation and police say they are keen to speak to anyone who saw what happened.

Officers particularly want to hear from a woman thought to be a district nurse who it's believed gave medical assistance to the injured motorbike rider.

Two men travelling in a black Mark 3 Ford Escort who stopped at the scene are also being sought.

Anyone with CCTV or dash cam footage of the incident is also being urged to contact police.

Sheffield scientists' bird behaviour breakthrough

PA Media

Scientists in South Yorkshire have used mathematical modelling developed by computer pioneer, maths genius and codebreaker Alan Turing to learn more about the behaviour of birds.

Researchers used the method to study why flocks of long-tailed tits segregate themselves into different parts of the landscape.

The team tracked the birds around Sheffield's Rivelin Valley which eventually produced a pattern across the landscape, and using maths helped the researchers to reveal the behaviours causing these patterns.

Natasha Ellison, the PhD student at the University of Sheffield who led the study, said: "Mathematical models help us understand nature in an extraordinary amount of ways and our study is a fantastic example of this.

"Long-tailed tits are too small to be fitted with GPS trackers like larger animals, so researchers follow these tiny birds on foot, listening for bird calls and identifying birds with binoculars.

"The field work is extremely time consuming and without the help of these mathematical models these behaviours wouldn't have been discovered."

Flocks of long-tailed tits are less likely to avoid places where they have interacted with relatives and more likely to avoid larger flocks, whilst preferring the centre of woodland, according to the findings published in the Journal of Animal Ecology.

It was previously unknown why the birds live in separate parts of the same area, despite there being plenty of food to sustain multiple flocks and the birds not showing territorial behaviour.

The equations used to understand the birds are similar to those developed by Alan Turing to describe how animals get their spotted and striped patterns.

Before the current study, these mathematical ideas had been used to understand the patterns made by territorial animals such as coyotes, meerkats and even human gangs.
