Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally. A key finding of the study is that…
While residents in California are still dealing with damage from last month’s floods — after years of devastating droughts — UBC Okanagan engineers are looking at better ways to manage the delivery of safe drinking water to homes. Things to consider include a changing climate, costs and sustainability. Dr. Haroon…
A team of researchers at the University of Houston is reporting the success of their new method for the early diagnosis and monitoring of lupus nephritis — at home. If you’ve taken an at-home COVID-19 or pregnancy test, then you’ve taken what is scientifically called a lateral flow assay (LFA)…

A University of Alberta researcher is one step closer to demonstrating the potential of a brain molecule called fractalkine to halt and even reverse the effects of multiple sclerosis and other neurodegenerative diseases. Multiple sclerosis is an autoimmune disease in which the myelin, or fatty lining of nerve cells, is…
Recent advances in newborn heart surgery have greatly reduced brain injuries in infants with congenital heart disease, according to a 20-year study by scientists at UCSF Benioff Children’s Hospitals and British Columbia Children’s Hospital (BCCH). The study, begun in 2001 and published this month in the Journal of the American…
In the search for new forces and interactions beyond the Standard Model, an international team of researchers involving the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz has now taken a good step forward. The researchers, among them Prof. Dr. Dmitry Budker, are…
Many educational approaches assume that integrating complementary sensory and motor information into the learning experience can enhance learning, for example gestures help in learning new vocabulary in foreign language classes. In her recent publication, neuroscientist Katharina von Kriegstein from Technische Universität Dresden and Brian Mathias of the University of Aberdeen…
The quail could be the unknown reservoir of the Toscana virus (TOSV) and the Sandfly Fever Sicilian virus (SFSV), mosquito-borne pathogens that can infect domestic animals and also cause disease in humans. This conclusion is drawn from a study published in the journal Frontiers in Microbiology, and which is led…
A study led by a North Carolina State University researcher found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading…
Scientists from the Institut Pasteur, Necker-Enfants Malades Hospital (AP-HP), Inserm in the Imagine Institute, Université Paris Cité and the Alfort National Veterinary School (EnvA) have identified a previously unknown species of circovirus, provisionally named human circovirus 1 (HCirV-1). Circoviruses are a family of small, highly resistant DNA viruses that were…
Here’s something else chess players need to keep in check: air pollution. That’s the bottom line of a newly published study co-authored by an MIT researcher, showing that chess players perform objectively worse and make more suboptimal moves, as measured by a computerized analysis of their games, when there is…
Insects play crucial roles in almost every ecosystem — they pollinate more than 80% of plants and are a major source of food for thousands of vertebrate species — but insect populations are collapsing around the globe, and they continue to be overlooked by conservation efforts. Protected areas can safeguard…
The CT-scanned skull of a 319-million-year-old fossilized fish, pulled from a coal mine in England more than a century ago, has revealed the oldest example of a well-preserved vertebrate brain. The brain and its cranial nerves are roughly an inch long and belong to an extinct bluegill-size fish. The discovery…
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material’s own natural frequency can send its vibrations into overdrive, causing the glass to…
Take apart your laptop screen, and at its heart you’ll find a plate patterned with pixels of red, green, and blue LEDs, arranged end to end like a meticulous Lite Brite display. When electrically powered, the LEDs together can produce every shade in the rainbow to generate full-color displays. Over…
New research from the Centre for Cancer Immunology at the University of Southampton, published ahead of World Cancer Day (4 February), has shown that changing how tightly an antibody binds to a target could improve treatments for cancer. Antibodies detect and tag viruses and bacteria so the body’s immune system…
Astronomers using the SMARTS 1.5-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab, have uncovered the first example of a phenomenally rare type of binary star system, one that has all the right conditions to eventually trigger a kilonova — the ultra-powerful, gold-producing explosion created…
More than three times as many houses and other structures burned in Western wildfires in 2010-2020 than in the previous decade, and that wasn’t only because more acreage burned, a new analysis has found. Human ignitions started 76% of the wildfires that destroyed structures, and those fires tended to be…
Neutrinos are one of the most abundant particles in our universe, but they are notoriously difficult to detect and study: they don’t have an electrical charge and have nearly no mass. They are often referred to as “ghost particles” because they rarely interact with atoms. But because they are so…
