Governments face a dilemma in responding to the COVID-19 pandemic - impose an early lockdown to slow the virus' spread and encourage good health practice or delay to protect jobs and learn more about how the virus behaves, a new study reveals. Early lockdown encourages people to adopt certain habits, such as hand washing and wearing masks, which they continue even when restrictions are lifted.
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.
Increased green space in prisons can reduce self-harm and violence
Prisons with more green space have lower levels of violence and self-harm, according to new research at the University of Birmingham and Utrecht University. The study is the first to attempt large-scale mapping of green space within prison environments and link it to well-being in a robust, statistically significant way.

Aerodynamic shape optimization for helicopter rotor heads Helicopters are to become faster, greener and quieter. An international team led by Airbus Helicopters (AH) is working on the technology to achieve these goals with the RACER demonstrator. Scientists from the Technical University of Munich (TUM) have designed an aerodynamically shape-optimized rotor head full fairing for the innovative RACER rotorcraft.
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.

Researchers have mapped the physical organisation of the brain of a soil-living nematode worm, creating a new model for the architecture of the animal's brain. They found a large degree of variation in the structure of some neural circuits or pathways in individual worms which complemented a core set of neural circuits common to the animals.
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...

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.
Scientists led by EPFL have developed a breakthrough in vivo model for invasive lobular carcinoma, a serious yet understudied type of breast cancer. The work will open up previously inaccessible study of the tumor's biology and help discover new therapies. Invasive lobular carcinoma (ILC) is a type of breast cancer that begins in the milk-producing glands (lobules) of the breast.
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.
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.
Recerca Air pollution from fuel combustion is one of the greatest environmental problems, especially in urban environments. In densely populated cities, the presence of nitrogen oxides, very small carbon particles, and carbon monoxide (CO) in the air seriously harms the human health and increases mortality.
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.

UChicago, Argonne scientists zero in on molecules that could fight COVID-19
A unique partnership among biologists, chemists and X-ray scientists at the University of Chicago and Argonne National Laboratory has zeroed in on several molecules that could be used to create drugs to fight COVID-19. Their results, published in Nature Communications , help scientists understand the shape and structure of the virus and how it works-and how it can be blocked.

Leaders in sports, business and politics get credit-and blame. How much do they really deserve?
After winning six Super Bowls with the New England Patriots, quarterback Tom Brady won an unprecedented seventh championship in 2021 with the Tampa Bay Buccaneers-raising questions about how much he needed Patriots head coach Bill Belichick to win his six previous titles. In the business world, investors might be asking themselves something similar as Jeff Bezos transitions out of his role as Amazon's CEO.

New Insight into Nonlinear Optical Resonators Unlocks Door to Numerous Potential Applications
Optical resonators, which circulate and confine light (for instance in lasers), are currently used in a variety of applications of all sizes-from pinpoint light sources smaller than the width of a human hair to kilometer-scale sensing devices such as the Laser Interferometer Gravitational-wave Observatory (LIGO) experiment that detects gravitational waves.

India is the world's second-largest producer of wheat and rice and is home to more than 600 million farmers. The country has achieved impressive food-production gains since the 1960s, due in part to an increased reliance on irrigation wells, which allowed Indian farmers to expand production into the mostly dry winter and summer seasons.
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.
International travellers are particularly vulnerable to virulent strains of drug-resistant bacteria - often picking up several different types during a trip through spending time in the company of other tourists, a new study reveals. The global spread of intestinal multidrug resistant gram-negative (MDR-GN) bacteria poses a serious threat to human health worldwide, with MDR clones of E.coli and Klebsiella pneumoniae threatening more antibiotic resistant infections around the world.
