Quark-gluon plasma flows like water, according to new study


 E-Mail
What does quark-gluon plasma - the hot soup of elementary particles formed a few microseconds after the Big Bang - have in common with tap water? Scientists say it s the way it flows.
A new study, published today in the journal
SciPost Physics, has highlighted the surprising similarities between quark-gluon plasma, the first matter thought to have filled the early Universe, and water that comes from our tap.
The ratio between the viscosity of a fluid, the measure of how runny it is, and its density, decides how it flows. Whilst both the viscosity and density of quark-gluon plasma are about 16 orders of magnitude larger than in water, the researchers found that the ratio between the viscosity and density of the two types of fluids are the same. This suggests that one of the most exotic states of matter known to exist in our universe would flow out of your tap in much the same way as water. ....

Subsidies most effective way to encourage sustainable food choices, study shows


 E-Mail
Subsidising low carbon emission meals could encourage more people to choose them, according to new research.
The study, led by Queen Mary University of London, investigated the impact of different interventions on encouraging people to select low carbon emission menu options in a simulated lunchtime canteen environment. This included the use of carbon taxes and subsidies, traffic light labelling (TLL) and social norms, where more sustainable options were highlighted as the most popular menu items.
Carbon taxes and either behavioral intervention - TLL or social norms - had a limited effect on shifting behaviours towards meal choices with lower carbon footprints. However, when all these interventions were combined with subsidies, where the money collected from carbon taxes for meat meals was added to vegetable only options, the researchers observed a 24 per cent reduction in weekly carbon emissions. ....

Scientists propose new way to detect emotions using wireless signals


 E-Mail
A novel artificial intelligence (AI) approach based on wireless signals could help to reveal our inner emotions, according to new research from Queen Mary University of London.
The study, published in the journal
PLOS ONE, demonstrates the use of radio waves to measure heartrate and breathing signals and predict how someone is feeling even in the absence of any other visual cues, such as facial expressions.
Participants were initially asked to watch a video selected by researchers for its ability to evoke one of four basic emotion types; anger, sadness, joy and pleasure. Whilst the individual was watching the video the researchers then emitted harmless radio signals, like those transmitted from any wireless system including radar or WiFi, towards the individual and measured the signals that bounced back off them. By analysing changes to these signals caused by slight body movements, the researchers were able to reveal hidden information about an indivi ....

Commuting patterns could explain higher incidence of Covid-19 in Black Americans


 E-Mail
The disproportionately high Covid-19 infection rates observed in Black Americans could be linked to their daily commuting patterns, according to a new study published today in the
Journal of the Royal Society Interface.
The research found that increased exposure to other ethnic groups, for example as a result of an individual s job or use of public transport, can result in the emergence of an infection gap in the population, such as the abnormally high incidence of Covid-19 recorded in Black Americans.
In some areas of the US Covid-19 incidence in Black Americans can be up to three to five times higher than would be expected based on population data. Previous studies have highlighted socio-economic factors including lower income and poorer access to healthcare facilities could play a role in this infection gap but these factors alone cannot completely explain the disproportionate impact of the pandemic on Black Americans. ....
