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.

Vaccinated people with breakthrough COVID infections had lower viral loads
Vaccinated health care workers who experienced breakthrough COVID-19 infections during the winter of 2020-21 had lower viral loads than their similarly infected but unvaccinated co-workers, according to a new UCLA study.

New mothers could help protect other babies’ brains
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.

Single blood test to measure T-cell and antibody response to SARS-CoV-2
Single blood test to measure T-cell and antibody response to SARS-CoV-2
A test to measure both the T-cell and antibody response to SARS-CoV-2 in a single blood sample has been developed by scientists at Cardiff University. The unique approach can also be used to measure the immune response brought about by vaccination and previous infection. It was developed in collaboration with Wales-based biotechnology company ImmunoServ Ltd and is outlined in a study published in the journal Immunology.

Wireless Devices Help Monitor Livestock Health and Location
Carnegie Mellon University Livestock like cows, horses and bison are typically managed as large herds and require massive expanses of pasture. While this group-based management has significantly increased productivity, it makes continuous monitoring of animal health and well-being labor-intensive and challenging.

Behold - the bendability of tectonic plates
Behold - the bendability of tectonic plates
A new study introduces a novel way for tectonic plates - massive sheets of rock that jostle for position in the Earth's crust and upper mantle - to bend and sink. It's a bit of planetary Pilates that may solve the longstanding mystery of "subduction," the process by which tectonic plates plunge deep into the Earth's interior.

Turning Up the Heat: Thermal Energy Storage Could Play Major Role in Decarbonizing Buildings
Berkeley Lab research efforts in advanced materials and cost analyses give major boost to an overlooked technology Berkeley Lab researchers have reported a breakthrough in phase-change materials, which will improve the affordability of thermal energy storage. Phase-change materials can be added inside walls and automatically keep a building cool or warm depending on the ambient temperature.

New analysis predicts how well vaccines will work against COVID-19 strains
Vaccines are less effective against some COVID-19 variants and boosting may be required within one year to maintain efficacy above 50 per cent, according to a new study. The researchers from the Sydney Institute for Infectious Diseases at the University of Sydney, UNSW Sydney's Kirby Institute and the University of Melbourne's Doherty Institute have conducted an analysis that can help inform the COVID-19 response by identifying an 'immune correlate' of vaccine protection.

When the senses get confused
UdeMNouvelles A gene linked to intellectural disability and epilepsy might also be playing havoc with some patients' senses, including sight and hearing, a new UdeM-led study suggests. The SYNGAP1 gene, recently recognized for its role in intellectual disability and epilepsy, may also affect the sensory system of patients with a genetic mutation linked to this gene.

Researchers from U-M, MSU, OU team up to develop wearable pollution-measuring technology
A walk in the park could soon include getting real-time measurements of pollutants in the air and updated walking routes to avoid the most toxic ones, all while wearing a gadget the size of a smart watch. With the support of a $2.78 million grant from the National Institutes of Health, researchers at the University of Michigan, Michigan State University and Oakland University are teaming up to develop wearable technology able to identify particulate matter pollution such as soot and toxic metals generated by cars, trucks and industrial sources.
