Fundamental particles modelled in beam of light
Share this page Share on Twitter Share on facebook Share on linkedin Share on email Scientists at the University of Birmingham have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light. The breakthrough provides physicists with a real system demonstrating the behaviour of skyrmions, first proposed 60 years ago by a University of Birmingham mathematical physicist, Professor Tony Skyrme.

Logistical Herculean Tasks
Logistical Herculean Tasks
11/22/2021 The question of the causes of species extinction confronts science with complex tasks. Dr Sarah Redlich from the Biocentre on the challenge of creating a study design. Research groups all over the world are trying to disentangle the causes of biodiversity loss. One thing is clear: there is no single cause.

How Well Do Wet Masks Contain Droplets?
Study shows damp masks still stop respiratory droplet penetration After studying the effectiveness of varying layers of masks in stopping respiratory droplets from escaping face masks, a team of international researchers has now turned their attention to modeling what happens to droplets when they come in contact with wet masks.

SPARKing the fight against deadly superbugs
Disarming superbugs that can cause deadly infections is the focus of a powerful database now housed at The University of Queensland. The database and virtual laboratory, called SPARK, aims to foster the development of new antibiotics to prevent projections of 10 million deaths globally per year from superbugs by 2050.

How smart is an octopus?
The unique brainpower of octopuses - known for their intelligence and Houdini-like escapes - has been revealed by University of Queensland researchers. Dr Wen-Sung Chung from UQ's Queensland Brain Institute is part of a team that studied four octopus species using MRI techniques to produce detailed 3D images for comparing their unique brain structures.

Justinianic Plague was nothing like flu and may have struck England before it reached Constantinople, new study suggests | University of Cambridge
Justinianic Plague was nothing like flu and may have struck England before it reached Constantinople, new study suggests | University of Cambridge
'Plague sceptics' are wrong to underestimate the devastating impact that bubonic plague had in the 6th- 8th centuries CE, argues a new study based on ancient texts and recent genetic discoveries. The same study suggests that bubonic plague may have reached England before its first recorded case in the Mediterranean via a currently unknown route, possibly involving the Baltic and Scandinavia.

Exposure to Harmless Coronaviruses Boosts SARS-CoV-2 Immunity
Exposure to Harmless Coronaviruses Boosts SARS-CoV-2 Immunity
Infections with the novel coronavirus and vaccination lead to strong antibody responses against SARS-CoV-2. Immune responses to other human coronaviruses, which mostly only cause harmless colds, also provide some protection against SARS-CoV-2. This cross-reactive immune response is an important piece of the puzzle of how to achieve comprehensive coronavirus immunity, researchers at the University of Zurich have shown.

Dentists at lower risk of getting COVID-19: Study
Dentists at lower risk of getting COVID-19: Study
Does close contact with patients put dentists at greater risk of catching COVID-19?  According to a new study by researchers at the University of Toronto and three other Canadian universities, dentists appear - perhaps counterintuitively - less likely than the general population to contract the virus.

Medicine by researchers generate cells to treat bile duct disorders resulting from cystic fibrosis
Researchers at the University of Toronto and its partner hospitals have discovered a way to generate functional cells from stem cells that could open new treatment avenues for people with cystic fibrosis who have liver disease. Funded by Medicine by Design and completed with the collaborative efforts of multiple labs, the research was recently published in  Nature Communications.

Refuting A 70-year Approach To Predicting Material Microstructure
Carnegie Mellon University A 70-year-old model used to predict the microstructure of materials doesn't work, according to Carnegie Mellon researchers in Science. A microscopy technique developed by Carnegie Mellon and Argonne National Laboratory yields evidence that contradicts the conventional model and points the way toward the use of new types of characterizations to predict properties - and therefore the safety and long-term durability - of new materials.

What it takes to eat a poisonous butterfly
Where monarch butterflies overwinter by the thousands to millions (left, a cluster in California), the black-headed grosbeak (right) is one of few birds that can eat them without vomiting. Researchers discovered that the bird has evolved similar genetic mutations as those found in the monarch that allow both to handle milkweed toxins, which accumulate in the butterfly and are deterrents to most predators.

White households in US emit most carbon despite greater energy efficiency
Residential energy use represents roughly one-fifth of annual greenhouse gas emissions in the United States. A team of researchers from McGill University and the University of Michigan has used data from 60 million individual American households to look into how carbon emissions caused by household energy use vary by race and ethnicity across the country.

Kids, teens believe girls aren’t interested in computer science
Children as young as age 6 develop ideas that girls are less interested than boys in computer science and engineering - stereotypes that can extend into the late teens and contribute to a gender gap in STEM college courses and related careers. New research from the University of Houston and the University of Washington, published Nov.

Rare mosquito-borne viruses found to be widespread in Florida Everglades
A team of research scientists led by the Yale School of Public Health has detected the presence of little-known mosquito-borne viruses endemic to the Florida Everglades throughout the wetland preserve, raising concern about future public health threats. In four large nature areas encompassing over one million acres in the Everglades, the team conducted a two-year study of mosquitoes and the viruses they carry.

Online purchases prove popular in pandemic
Aussies spent big online during the pandemic, but it was physical retailer websites that outperformed online-only websites, a new report by Monash researchers has found. Research by Monash Business School's Australian Consumer and Retail Studies (ACRS) confirmed what we already assumed: eCommerce spending habits surged during lockdowns.

How unhealthy diet makes you sick
How unhealthy diet makes you sick
New link between diet, intestinal stem cells and disease discovered Obesity, diabetes and gastrointestinal cancer are frequently linked to an unhealthy diet. However, the molecular mechanisms responsible for this are hitherto not fully understood. Researchers at the Technical University of Munich and Helmholtz Munich have gained some new insights that help to better understand this connection.

Unborn babies could contract Covid-19 finds study, but it would be uncommon
An unborn baby could become infected with Covid-19 if their gut is exposed to the SARS-CoV-2 virus, finds a new study led by UCL researchers with Great Ormond Street Hospital for Children and the NIHR Great Ormond Street Biomedical Research Centre. Although the study did not look specifically at mothers with Covid-19 and whether their infection was transmitted to an unborn baby, it found that certain fetal organs, such as the intestine, are more susceptible to infection than others.

The placenta from mothers of healthy newborns could one day be used to reduce brain injury in growth-restricted babies, according to University of Queensland research. Dr Julie Wixey from UQ's Centre for Clinical Research said the study found stem cells sourced from a healthy placenta may reduce damaging inflammation in these babies after only three days.

People with chronic kidney disease are vulnerable to hospitalisation
People with multiple health conditions - known as multimorbidity - are at risk of unplanned admissions to hospital. Now, new research has found the rates of hospitalisation in these people are even higher if one of their conditions is chronic kidney disease. The new research, led by the University of Glasgow and published in BMC Medicine, examined the rates of hospitalisation in people with multimorbidity, including those who also have chronic kidney disease as one of those conditions.
