Supporting actors take lead role as our brains age
Supporting actors take lead role as our brains age
The main changes in our brains as we get older are in the brain cells with a supporting role, called glial cells, British scientists have found. The surprising finding in a study by researchers at UCL and the Francis Crick Institute is published in the journal Cell Reports. The researchers also found that the greatest changes in glial cells as we age are in the brain regions most often damaged by neurodegenerative disease, like Alzheimer's and Parkinson's.

The best way to include fossils in the 'tree of life'
The best way to include fossils in the ’tree of life’
A team of scientists from the University of Bristol has suggested that we need to use a fresh approach to analyse relationships in the fossil record to show how all living and extinct species are related in the 'tree of life'. The researchers from the Bristol Palaeobiology Group , part of the School of Earth Sciences , studied the best way to understand relationships of extinct animals to other extinct species as well as those alive today.

High-sugar diet programmes a short lifespan in flies
High-sugar diet programmes a short lifespan in flies
Flies with a history of eating a high sugar diet live shorter lives, even after their diet improves. This is because the unhealthy diet drives long-term reprogramming of gene expression, according to a UCL-led team of researchers. The study, published today in Cell Reports , discovered that the action of a gene called FOXO is inhibited in flies given a high sugar diet in early life, causing long-term effects.

Crohn's disease risk and prognosis determined by different genes, study finds
Crohn’s disease risk and prognosis determined by different genes, study finds
Researchers have identified a series of genetic variants that affect the severity of Crohn's disease, an inflammatory bowel disease - but surprisingly, none of these variants appear to be related to an individual's risk of developing the condition in the first place.

Retroviruses ’almost half a billion years old’
Researchers have found that retroviruses could be half a billion years old - several hundred million years older than previously thought. Retroviruses - the family of viruses that includes HIV - are almost half a billion years old, according to new research by scientists at Oxford University. That's several hundred million years older than previously thought and suggests retroviruses have ancient marine origins, having been with their animal hosts through the evolutionary transition from sea to land.

Mediterranean diet may protect your brain in old age, new finding suggests
Mediterranean diet may protect your brain in old age, new finding suggests
Could a Mediterranean diet keep your brain young? That is the tantalising finding from a study out this week. Writing on The Conversation website, Professor Paul Fletcher from the Department of Psychiatry investigates the findings. Amid the contention about diets and detoxes, sugar and fats, there is at least general agreement that a Mediterranean diet - fruit, vegetables, olive oil, grains, fish - is a good thing.

Bacteria resists 'last-resort' antibiotic
Bacteria resists ’last-resort’ antibiotic
An international research team, led by the University of Bristol, has provided the first clues to understand how the mcr-1 gene protects bacteria from colistin - a 'last resort' antibiotic used to treat life-threatening bacterial infections that do not respond to other treatment options.

‘Molecular volume control’ may help combat tumours
A 'molecular volume control' may one day be used to manipulate enzyme activity in order control the development and treatment of cancer, according to research at the Universities of Dundee and Bath. The researchers have uncovered new functions of an enzyme called Dual-specificity phosphatase 5 (DUSP5), which will help scientists to better understand how tumours develop.

Genetics play a significant role in immunity
Nearly three quarters of immune traits are influenced by genes, new research from King's reveals. The study published today , adds to a growing body of evidence that the genetic influence on our immune system is significantly higher than previously thought. Researchers from King's, supported by the NIHR Biomedical Research Centre at Guy's and St Thomas' Foundation Trust and King's College London, analysed 23,000 immune traits in 497 adult female twins from the TwinsUK cohort.
