Ten leading universities conduct over one third of all UK animal research
Mass extinctions were followed by periods of low diversity in which certain new species dominated wide regions of the supercontinent Pangaea, reports a new study. The findings indicate that mass extinctions may have predictable consequences and provide insights into how biological communities may be expected to change in the future as a result of current high extinction rates.

Scientists identify mechanism that helps us inhibit unwanted thoughts
Scientists have identified a key chemical within the 'memory' region of the brain that allows us to suppress unwanted thoughts, helping explain why people who suffer from disorders such as anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often experience persistent intrusive thoughts when these circuits go awry.

Bacterial population struggles can affect the potential of vaccines
Scientists have shown how vaccinating against a common cause of pneumonia leads to lethal strains of bacteria being replaced by less harmful strains. The study provides a clearer picture of the complex population structures of bacteria and how different strains struggle to establish themselves. According to the researchers, the findings could help to optimise new vaccines by predicting how they will change bacterial populations in the longer term, based on how common certain genes are among the bugs.

Food shortage is not the global crisis, lack of access to food is the issue - say NGOs
'Genome editing is not the answer to world poverty, because food shortage isn't the problem' says a group of non-governmental organisations (NGOs) surveyed by the University of Nottingham. This is one of three main findings in a report from the School of Sociology and Social Policy at the University, which looks at NGO's scepticism of genome editing technology.

Horses can read our body language, even when they don’t know us
Horses can read our body language, even when they don't know us Horses can tell the difference between dominant and submissive body postures in humans, even when the humans are not familiar to them, according to a new University of Sussex-led study. The findings enhance our understanding of how animals can communicate using body posture across the species barrier, and are specifically helpful for informing horse handlers and trainers about the ways horses perceive human body language.

Colon cancer breakthrough could lead to prevention
Colon cancer, Crohn's, and other gut diseases could be better treated or prevented, thanks to a new link between inflammation and a common cellular process, found by University of Warwick Autophagy - an essential process whereby cells break down and recycle harmful elements to keep our bodies healthy - causes tissue inflammation when dysfunctional, which in turn leaves us susceptible to diseases, particularly in the gut Pomegranates, red grapes,

Life on the Edge
Many species, such as vine snakes in the Amazon, favour the darker and more humid forest interiors. Photo: Professor Jos Barlow Breaking up the rainforest into small, isolated patches is forcing more species to live at the forest edge and putting those that are dependent on the forest core at risk. Research published today in the academic journal Nature highlights how biodiversity is changing as a result of deforestation - forcing some species to the brink of extinction while others flourish in the changing environment.

Nobel Prize-winning technique sheds new light on DNA replication
An imaging technique used to reveal the molecular detail of structures has helped scientists to shed new light on how organisms copy their DNA. The international team, which included Imperial scientists, used cryo-electron microscopy - the technique behind this year's Nobel Prize in Chemistry - to reveal the structure of a key enzyme involved in the earliest steps of the DNA replication process.

Brain tumour’s ’addiction’ to common amino acid could be its weakness
Starving a childhood brain tumour of the amino acid glutamine could improve the effect of chemotherapy, according to an early study led by Queen Mary University of London (QMUL) and funded by Children with Cancer UK and the Medical Research Council. Wednesday 1 November 2017 Medulloblastoma is the most common solid primary brain tumour in children and a major cause of mortality in childhood cancers.

Reviving old drugs could help to stem the rise of drug-resistant gonorrhoea
A new study suggests a drug that was used in the past to treat gonorrhoea could help tackle infections that are resistant to current treatments. Cases of the sexually transmitted infection gonorrhoea have been rising in recent years and the bacteria that cause it are becoming increasingly resistant to the antibiotics currently used, in some cases making it impossible to treat.

Aliens may be more like us than we think
Hollywood films and science fiction literature fuel the belief that aliens are monster-like beings, who are very different to humans. But new research suggests that we could have more in common with our extra-terrestrial neighbours, than initially thought. In a new study published in the International Journal of Astrobiology scientists from the University of Oxford show for the first time how evolutionary theory can be used to support alien predictions and better understand their behaviour.

The relentless rise of migration in Europe over last 10,000 years
Three major pulses of increased mobility in Europe over the last 10,000 years and a general upward trend in migration have been uncovered in a new study led by researchers from UCL, University of Cambridge and King's College London. The new method, published today in PNAS , allows, for the first time, to directly quantify changes in prehistoric migration rates using ancient genetic data over the last 30,000 years.

The advent of "green” cattle
Implications of livestock farming on climate change should not be drawn from aggregate statistics, reveals a study based on a new method of carbon footprinting for pasture-based cattle production systems that can assess the impacts of individual animals. The new method, developed by a team from the University of Bristol and Rothamsted Research, records the environmental impact of each animal separately before calculating the overall burden of a farm.

Cancer drug could help patients with debilitating cardiovascular condition
UK and Canadian scientists have shown how patients with a rare cardiovascular condition could be treated with a drug normally used to treat cancer. Pulmonary Arterial Hypertension (PAH) is a life-threatening disease that affects the blood vessels of the lung and causes heart failure. In a paper the team from Imperial College London and the University of Alberta report promising results from an early-phase clinical trial in a small group of patients with PAH already under treatment with approved drugs, as well as lung tissue from PAH patients.
