New clues to halting nerve degeneration
A discovery into the mechanisms which lead to degeneration and loss of communication among neuron cells - the cells controlling function in the brain and nervous system - could potentially lead to future therapies for neurodegenerative diseases including Parkinson's and Alzheimer's. Scientists at The University of Nottingham have discovered that a small molecule called nicotinamide mononucleotide (NMN) causes a chain reaction of destruction within the neuron cell processes, called axons.

More than half of England's poorest citizens risk undetected bowel cancer
More than half of England’s poorest citizens risk undetected bowel cancer
The study was set up to test ways of narrowing the gap in uptake between rich and poor. The results highlight just how wide this gap currently is, and also provide the first published national figures on bowel screening uptake since the scheme was fully rolled out in 2010. Four randomised controlled trials were conducted across the whole of England to see if uptake could be increased, particularly among the most disadvantaged members of society, by making cheap, simple and easy-to-implement changes to the screening invitation letters and information materials.

Alzheimer’s study probes chemistry of the brain
State-of-the-art simulations will investigate the cause and potential prevention of plaque build-up in the brain Experts at the University are using state-of-the-art computer simulations to study the fundamental chemistry underpinning the development of Alzheimer's disease. Dr Jamie Platts, from the School of Chemistry , has been awarded a major research grant to investigate the build-up of ‘sticky' plaques in the brain, which are believed to contribute to the degradation of nerve cells in the brain and the subsequent symptoms of Alzheimer's disease.

Quantum physics problem proved unsolvable
Quantum physics problem proved unsolvable
A mathematical problem underlying fundamental questions in particle physics and quantum physics is provably unsolvable, according to scientists at UCL, Universidad Complutense de Madrid - ICMAT and Technische Universität München. The findings show that even a perfect and complete description of the microscopic properties of a material is not enough to predict its macroscopic behaviour.

Blood test that could predict arthritis risk
Scientists have found a marker that can indicate your likelihood of suffering from rheumatoid arthritis (RA) even sixteen years before the condition takes effect. A team from the Kennedy Institute of Rheumatology at Oxford University found that a blood test that looks for antibodies that recognize the protein tenascin-C could reliably show those who will contract the condition.

Scientists create first map of the wheat epigenome
Scientists create first map of the wheat epigenome
Scientists at the University of Liverpool have carried out the first ever genome-wide survey of heritable molecular changes that regulate gene activity in wheat, in what could become a new tool to improve crop breeding technologies. Epigenetic marks are chemical tags which physically attach themselves to DNA, and modify its function without changing the genetic code.

Behavioural problems in youths are associated with differences in the brain
Young people with behavioural problems, such as antisocial and aggressive behaviour, show reduced grey matter volume in a number of areas of the brain, according to a new study published in JAMA Psychiatry . The researchers from the University of Birmingham found that, compared to typically developing youths, those with behavioural problems show grey matter reductions specifically within the amygdala, the insula, and the prefrontal cortex.

Why focusing on a visual task will make us deaf to our surroundings
Why focusing on a visual task will make us deaf to our surroundings
Concentrating attention on a visual task can render you momentarily 'deaf' to sounds at normal levels, reports a new UCL study funded by the Wellcome Trust. The study, published in the Journal of Neuroscience, suggests that the senses of hearing and vision share a limited neural resource. Brain scans from 13 volunteers found that when they were engaged in a demanding visual task, the brain response to sound was significantly reduced.

Difficult birth for the universe provides clues to particle physics mystery
Difficult birth for the universe provides clues to particle physics mystery
After studying why the universe did not collapse during its birth, researchers are closer to finding a missing piece in the Standard Model of physics. Since the discovery of the Higgs particle - responsible for giving mass to all particles - at CERN in 2012, studies of its properties have thrown up a lot of questions.

Happiness and unhappiness have no direct effect on mortality
A study of a million UK women, published today in  The Lancet ,  has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect.  Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality.

Older people would be willing to boost bone strength by giving jumping exercises a try
Older people would be willing to boost bone strength by giving jumping exercises a try
Older people would be willing to increase their bone strength in later life by doing exercises including jumping and hopping, new research from Bristol University has found. The study, funded by the Medical Research Council award to Professor Jon Tobias in the Musculoskeletal Research Unit, found that if older people overcome the barriers to undertaking the exercises, they would be willing to undertake the type of exercises that are likely to increase their bone density and strength, which in turn could reduce their risk of falls or bone fractures.

Human trials suggest ’rescued’ drug could be safer treatment for bipolar disorder
A drug destined for the scrap heap has been rescued by Oxford scientists, who may have found it a new role in treating bipolar disorder. A team from Oxford University, led by Dr Grant Churchill and Dr Sridhar Vasudevan of the Department of Pharmacology, in collaboration with Professor Phil Cowen of the Department of Psychiatry, used a database of 'failed' drugs, found to be safe but ineffective for their proposed use, to identify ebselen as a possible alternative to lithium, the main treatment for people who are bipolar.
