Following the branch’s AGM Tim Thompson, professor of forensic anthropology at Teeside University, talked to members about the role of the forensic anthropologist – including the procedures and research involved in establishing the identity of human remains, and the ways in which the human body can be studied to provide information regarding death, particularly with regard to cases of mass killing.
Tim showed how an osteo-profile is created taking into account diagenesis and taphonomic processes, ie the external factors that can result in changes to skeletal remains. Details can point to the means of death and whether a crime has been committed. As an example, a collection of skulls found during the Cross Rail excavations was shown to be due to water flow through a cemetery rather than the aftermath of violence.He also outlined the problems of distinguishing and identifying commingled individuals in mass graves. The large amount of data gathered from such events is contributing to the rapid growth of the science.
The importance of human biology in the work of forensic practitioners and investigators can be seen in the Border Crossings Project which seeks to identify deaths of undocumented migrants across the US Mexico border, and in the Anthropological Verification Project which attempts to ensure the integrity of human remains. Bizarrely we learned that the toe bones are the most reliable source of information.
This is a relatively young field of study brought into public consciousness by prominent murder cases and events such as 9/11, war, and by the popular media.
Against the atmospheric background of a crashing Middlesbrough thunderstorm, this interesting and entertaining talk illuminated the application of current research in forensic anthropology.

Hauxley Nature Reserve in Northumberland lies to the North of the magnificent sweep of Druridge Bay. The reserve is managed by Northumberland Wildlife Trust (NWT) and is dominated by a lake fronting the dunes. Our visit coincided with a rush of enthusiasts who had come to see the unexpected and accidental arrival of a spotted sandpiper from North America.
In 2010, the reserve suffered a setback when the visitor centre was destroyed by fire. Since then NWT has raised funds, including a major contribution from the National Lottery, and with the help of around 120 local volunteers, is constructing a new visitor centre and making substantial improvements to the reserve.
Members of the branch, together with two welcome visitors from the Yorkshire branch, were given a tour of the new facility by Alex Lister, the Druridge Bay reserves manager. Although the centre is still under construction, we were able to see the high standards of eco-build using sustainable local materials including straw insulation, sand/clay flooring, Douglas fir pillars sourced from one of the Trust’s own reserves and a turf roof.
The building has panoramic views over the reserve and, as well as acting as a gateway, will incorporate a shop, café and an education centre.
We were able to take advantage of the glorious weather to round off the day with a tour around the reserve to view the developing flower meadows and lake hides. Some of us even spotted the spotted sand piper!

The branch met at the College of St Hild and St Bede, Durham University. After a welcome and introduction by Dr Mike Cassidy, the secretary reviewed the year's activities, which included attendance at the Middlesbrough Imagineer Festival, sponsorship of an animal science conference at Newcastle and a successful and enjoyable Christmas dinner held in Durham to mark the award of the Royal Charter.
The current committee was re-elected and there was discussion about potential and planned activities for the year ahead.
The planned speaker was unfortunately not able to attend but we were fortunate that Mark Whittingham, professor of applied ecology at Newcastle University, and Dr David Brignall, regional director of the consultancy Wardell-Armstrong were able to give a joint talk on the intended theme of ecosystem services.
Mark talked about our understanding of biodiversity and about its human values which can be expressed in terms of both economy and wellbeing. The ways in which biodiversity contributes to these values forms the basis of ecosystem services.
The problems and challenges of biodiversity loss were also explored: David explained the nature of ecosystem services from the perspective of the consultant and the multidisciplinary approach involved in assessing the potential of interconnected and multiple effects of major projects on the environment.
He illustrated these problems and some of the ways in which negative effects can be mitigated with detailed reference to a wind farm project in the Shetlands, and work in Armenia on the development of a gold mine in an ecologically sensitive area.
This perceptive and lively presentation gave considerable insight into a very practical and important area of biology.

Members of the Northern branch and their guests celebrated the award of the Royal Charter to the Society at a Christmas dinner in the pleasant surroundings of the Lindisfarne Centre at St Aidan's College, Durham University.
Before the excellent festive meal we were fortunate in being able to view a display of the winning entries in the Society's latest photography and specimen drawing competitions together with the book prize winners. It is a few years since we last had a Christmas gathering and it is hoped that the success of this event will promise many more to come.

The branch met at Durham University in the Holgate conference centre at Grey College. The AGM was held in the morning and, after a welcome and introduction by the chairman, the year's events were reviewed including successful visits to the Durham brewery in June and to Northumbrian water scientific services in November. We were pleased to welcome Dr Penny Fletcher, Events and public engagement manager for the Society of Biology and Dr Jane Magill, Regional coordinator for Scotland and Northern England who each gave short presentations.
The chairman, Dr Clifford Wood, reported that he would not seek re-election and thanked the current and past members of the committee for their support. He paid particular tribute to the late Professor Donald Lee for his help and guidance. Cliff was thanked for his work and leadership of the branch during his ten years of office following a long period as a committee member.
Professor Sandra Edwards, the Vice Chair, had left the committee during the year as had Dr Douglas Wilson, and Dr Christine Masterson, the Events Secretary, did not wish to continue. Dr Cathleen Thomas and Dr Brian Degger were elected to the committee and the new committee comprises:
Mike Rowell indicated that he intended to phase out of office as soon as the new committee was firmly established. No chair was appointed and it was hoped that the official positions could in the future be a matter of shared responsibility. Any members who were unable to be at the meeting but who would like to join the committee would be very welcome.
After a buffet lunch, Professor Olivier Sparagano, Associate Pro Vice Chancellor for Research at Coventry University gave a lecture entitled The Emperor versus the Microbes. Olivier looked at the progression and failures of the Roman Empire and the brilliant successes and setbacks of Napoleon. During wars the main killers are not always soldiers and statistics show that the highest casualties are often the result of disease. He suggested that in counteracting infection the immune system follows the same strategy and that we should therefore learn from the best leaders, build the best armies, gather intelligence and develop new strategies. The body's own soldiers and weapons equate to the innate and adaptive immunity of defending cells and antibodies. The use of new techniques such as molecular diagnostics and vaccine development was illustrated by research against the poultry red mite – a major parasitic pest of economic importance. After a persuasive and entertaining talk the conclusion was that "the more you know about bugs the better to win the battles".

Branch member Lisa Bamford arranged for Northumbrian Water Scientific Services to host a visit of the Northern Branch at its dedicated microbiology laboratory at Horsley, in the Tyne Valley.
Though we take the provision of safe drinking water for granted, we can only do so because of the constant treatment and monitoring of the supply. In addition to routine testing of drinking water, the laboratory also offers services testing private water supplies, bathing and environmental waters.
After a welcome with coffee and cakes by the laboratory manager, John Cooper, Lisa and her colleagues John Kain, Bob Carrington, Gemma Calvert and Rachel Brown gave a detailed overview of the processes involved in purifying supplied water and in testing samples. After donning suitable protective gear, we were then taken in groups around the laboratories to see the actual methods used.
Water is routinely tested for indicators of faecal contamination - coliforms, Enterococci faecalis, and Clostridium perfringens - by using a range of selective media to isolate and confirm these organisms. The laboratory also tests water from public and private supplies for Legionella, the source of Legionnaires disease and a major cause of pneumonia.
Cryptosporidium parvum is commonly found in cow faeces and can cause the disease cryptosporidiosis with ingestion of as few as 10 to 30 oocysts. The parasite is resistant to chlorine and infected water must be boiled. High risk sites are monitored on a daily basis and since cryptosporidium can't be grown on selective media, it has to be isolated by filtration and identified microscopically. We were shown the labour intensive process involved in isolating the organism.
It would be difficult to imagine a world without easily accessible clean water and we are grateful to Northumbrian Water for hosting our visit and allowing us to see the detailed professional care and technology used to ensure our supplies.

Sixteen members and their guests met for a guided tour of The Durham Brewery, an independent family-run microbrewery which has won many awards since it was established by Steve and Christine Gibbs in 1994.
Steve talked about the history and processes of brewing and the growth of the microbrewing industry. During the last 20 years the market has changed dramatically with a decline in the number of large industrial breweries but with a demand for ‘real ale’ stimulating the growth of ‘craft’ brewers. Paradoxically, although there are now more brewers, their low volume enterprises mean that less beer is drunk.
The production of the ‘fermented malt beverage’ is more complex than wine making, and while historically ‘ale’ was a relatively unexciting drink, the treatment of malts, use of novel yeasts and the introduction of hops from the continent meant the flavour and strength of beer could be widely adjusted.
The difference between wine-tasting and beer-tasting is that it is necessary to swallow the product to fully appreciate the taste. So, as we were taken through the ways in which different malts, yeasts and hops affect appearance and taste, the group was able to carry out an empirical assessment of the ingredients.
The introduction was followed by a tour of the brewery.
Despite being a very modern plant, the brewery adopts a relatively traditional approach to the technology; the beers are not pasteurized or filtered and the flavours develop by conditioning with live sediment in the bottle or cask. Ongoing experimentation has resulted in a wide range of successful styles with, in some cases, the inclusion of ingredients such as raspberry and mango, and the introduction of an unfiltered wheat beer similar to German Heferweizen.
Following further discussion the group dispersed to their taxis having had an instructive and enjoyable afternoon – a winning experience of practical biotechnology.

The Annual General Meeting of the Northern branch was held at the Great North Museum, Hancock, Newcastle upon Tyne. Chairman Dr Cliff Wood reported the death of its honorary president, Professor Donald Lee, in September 2013. Donald had been an active chair, treasurer and for a period, secretary, of the committee – and at one point held all three offices together. In 2011 he was awarded the first of the Society of Biology's President's medal for his services. He will be greatly missed by the branch.
The following members were elected to the Committee: chairman - Dr Clifford Wood; vice chair - Professor Sandra Edwards; secretary - Dr Michael Rowell; events secretary - Dr Christine Masterson; acting treasurer - Dr Michael Rowell.
After the formal business of the meeting, members and their guests moved to the museum planetarium where they viewed the film Fragile Planet.

Twenty one final year animal science and agriculture students from Newcastle University hosted a conference to discuss current issues relating to animal health.
Within a six week time period we managed to raise £605 in donations, organise a strong and diverse range of guest speakers as well as prepare our own presentations on key topics surrounding our conference title, Animal Health Implications arising from Modern Human Demands.
The topics covered in our group presentations included mobility problems and mastitis in dairy cattle, the housing and welfare of poultry, selective breeding in canines and the health problems of exotic animals.
Leading race horse trainer Mark Johnston spoke on the ailments affecting the equine species and the approach to these in a thoroughbred stable. Nuffield Scholar Paul Robinson talked about his experience in the dairy industry, discussing his research and studies abroad with particular emphasis on the welfare and productivity of cattle in 'mega-dairies'. To conclude the conference, local veterinary surgeon Sam Prescott gave a thought provoking talk on the care and concerns of exotic animals.
The conference attracted a wide variety of guests, including students from colleges in the North East and representatives from organisations such BSAS and of course the Society of Biology.
We would like to thank our donors: BSAS; Society of Biology; Semex; Brooke Research Ltd; and Dr Guy from Newcastle University, without whose generous contributions the conference could not have gone ahead.
Overall, we received some excellent feedback, and we are hopeful that next year's students will be inspired to hold a great conference.

For the last few years, the Northern branch has awarded prizes for the best biology entries at the school science fair, Big Bang North East. This year the event was held at Newcastle University where, in addition to the National Science and Engineering Competition stands, there was an ongoing programme of science shows, workshops and activity zones.
Seventy-three school science and technology projects were on display, sixteen of which were biologically based. The branch secretary and a colleague talked to the enthusiastic exhibitors and - with some difficulty because of the extremely high standard of the entries - drew up a shortlist to recommend to the moderators.
The Northern branch prizes were awarded to Daniel Graham, Jack Bannister, Lucy Evanson, Steven Dixon and Holly French from Whickham School with a project entitled 'Studies of protein synthesis using live cell microscopy; and Olivia Jack, Hannah Schubeler, Beth Robertson, Nathan Smith Francesco Bello and Alfie Briggs from St Thomas More RC Academy with a project, 'Is the red you see the red I see?'.

On a beautiful spring day, eighteen members and their guests were given a tour of Newcastle University's Moorbank Botanic Garden by director, Dr Anne Borland. Moorbank, which lies a short distance from the city centre, houses the rare and extensive plant collections of Randle Cooke which were moved from his noted garden, Kilbryde, near Corbridge in 1973.
A series of connected glasshouses contain a wide range of plants including the Trevor Walker fern collection. The glasshouses are themed into areas such as tropical rainforest, economic plants, a pond and a desert house. The latter was the inspiration for the Leverhulme sponsored poet in residence, Linda France, whose compilation of renga verse is highlighted by a word sculpture in the desert house.
In addition to the research being carried out in the gardens, regular activities offer hands-on educational experience in the plant sciences and environmental biology to local schoolchildren and other groups. Unfortunately, Newcastle University is planning to withdraw its support from Moorbank Gardens in November and the future of the site, which is leased from the freemen of Newcastle, is uncertain, but supporters have drawn up a feasibility study to help maintain its present role.
Following the tour, Dr Borland gave a talk entitled why do we need plant scientists? She began by outlining the historic development of plant science and why an understanding of botany is increasingly important to world economy. She then gave a fascinating overview of the ways in which research into photosynthetic mechanisms- particularly CAM processes -can lead to increasing crop yields for both food and biofuels.
A buffet lunch was followed by the AGM. The chairman, Dr Cliff Wood, thanked the committee for their work and reviewed the year's events. He particularly expressed his appreciation to Mrs Muriel Woodward who was retiring from the committee after 25 years service. Dr Mike Cassidy was elected to the committee and the current officers and remaining members were re-elected.

Our AGM was held at Northumbrian Water Limited ETW and Advanced Digestion Plant at Bran Sands. Since only seven members were present, and no new nominations were received, the officers and committee were re-elected en bloc. Chair Dr Cliff Wood thanked the committee for their work but expressed concerns over the lack of support from branch members with consequences for the future viability of the branch. We have no Charter Lecture planned for this year although the branch will continue to support Big Bang NE and the student animal health conference.
Members learnt about the Bran Sands site, which lies at the mouth of the River Tees - a heavily industrialised area. Mike Ellner and Bernie Glanville from Northumbrian Water gave a short historical overview of sewage treatment and then detailed the development of the Bran Sands site.
The aim was to improve water quality within 12km of the Tees estuary and to introduce a more sustainable and effective sludge strategy. Prior to 1995, there was no coherent strategy for disposal of sludge with this material being sent to agricultural land, landfill or disposed of at sea. The advanced digestion plant at Bran Sands is a centralised facility utilising anaerobic, anoxic and aerobic biological treatment to deal with a range of organic and inorganic wastes producing clean effluent and a usable sludge for recycling to farmland. Biogas which is generated as a by-product is burnt in a CHP engine and used as a renewable energy source. As well as the economic benefits, the environmental impact can be seen in the quality of the river water with the Tees now supporting healthy salmon stocks and a thriving population of Harbour Seal in the estuary. Members were finally given a tour of this impressive site concluding an informative and rewarding day.
