Leave campaign created ’new religion’ to support EU withdrawal - study
Campaigners used quasi-religious and mythological themes to create a ‘Brexit religion' with the National Health Service (NHS) at its heart - persuading people to support Britain's withdrawal from the European Union, according to a new study. The Leave campaign's promise to ‘take back control' used the NHS as the country's Holy Grail that could be rescued from malign European forces that threatened Britain's unique historical place in the world.

Forget what you think you know about viral marketing, UCLA study suggests
Nearly everything author Malcolm Gladwell said about how information spreads in his 2000 bestseller “The Tipping Point? is wrong, according to a recent study led by UCLA professor of sociology Gabriel Rossman. “The main point of ‘The Tipping Point' is if you want your idea to spread, you find the most popular person in the center of any given network and you sell them on your idea , and then they'll sell the rest of the world on it,' Rossman said.

Solving a 100 year-old maths puzzle
For 100 years mathematicians have been trying to solve the question of whether it is possible to fit all four points of a rectangle into any given closed curve shape. Or, more bluntly, can you fit a square peg into a round hole? Research so far had found that it was only possible to fit the proverbial square peg into a round hole if the peg in question was of certain proportions, until now...

Warmer and wetter climates amplify carbon release
Warmer and wetter climates amplify carbon release
Terrestrial ecosystems help mitigate climate change by absorbing large amounts of carbon from the atmosphere. A new study now confirms that changing climate conditions could reduce this effect because in warmer and wetter areas, carbon stored in the soil is released back into the atmosphere more quickly.

Identification of 'violent' processes that cause wheezing could lead to better diagnosis and treatment for lung disease
Identification of ’violent’ processes that cause wheezing could lead to better diagnosis and treatment for lung disease
A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition that affects up to a quarter of the world's population. Since wheezing is associated with so many conditions, it is difficult to be sure of what is wrong with a patient just based on the wheeze Anurag Agarwal The researchers, from the University of Cambridge, used modelling and high-speed video techniques to show what causes wheezing and how to predict it.

Reactivating Aging Stem Cells in the Brain
Reactivating Aging Stem Cells in the Brain
As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked to stem cell aging - and how the production of neurons can be reactivated. The stem cells in our brain generate new neurons throughout life, for example in the hippocampus.

Video of ’dancing DNA’ developed by researchers
Videos showing for the first time how small circles of DNA adopt dance-like movements have been developed by a team led by researchers at UCL and the Universities of Leeds, York and Sheffield. The footage is based on some of the highest resolution images of a single molecule of DNA ever captured, with DNA seen to "dance" in microscopy data recorded at the London Centre for Nanotechnology at UCL.  The images show in unprecedented detail how the stresses and strains that are placed on DNA when it is crammed inside cells can change its shape.

Some men with testicular cancer may benefit from fewer CT scans
Patients who have had treatment for early-stage testicular cancer could benefit from fewer monitoring scans, reducing the harmful radiation they are exposed to from computerized tomography (CT) imaging, according to the results of a new clinical trial involving UCL researchers. Funded by Cancer Research UK and led by researchers at UCL, The Institute of Cancer Research, London, and Leeds/Huddersfield, the study found that using magnetic resonance imaging (MRI) instead of CT scans was as effective at picking up signs of cancer relapse.

Unexpected antimatter asymmetry in the proton
Symmetry is an important underlying structure of nature, present not only in mathematics and art, but also in living organisms and galaxies. Scientists originally thought protons, the positively charged particle at the center of every atom, displayed symmetry. But a research team that includes University of Michigan physicists has found the proton displays asymmetry in its makeup.
