UBCO researchers light the way to cleaner water

UBCO researchers light the way to cleaner water
2021-07-15
Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. UBC Okanagan researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise. When a beam of light is shone into the water, it excites the electrons in molecules of certain compounds and causes them to emit light. The characteristics of the emitted light are like a fingerprint and can be used to identify certain contaminants, explains Nicolas Peleato, an assistant professor at UBCO's School of Engineering. "The challenge with using this fluorescence approach is that ...

Repairs using light signals

2021-07-15
Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group led by Prof. Dr. Karl Mandel, Professorship of Inorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), has now developed a smart microparticle that enables defective components in these appliances to be identified more quickly and easily by using light signals. In the long-term, this could make repairs easier and extend the operating life of devices. The results have been published in the journal Advanced Functional Materials. To identify defective components in a device, particles known as supraparticles are applied to the individual parts. These particles measure between one and ten micrometres and under black light they provide information ...

Biomolecular bonsai: Controlling the pruning and strengthening of neuron branches

Biomolecular bonsai: Controlling the pruning and strengthening of neuron branches
2021-07-15
Fukuoka, Japan--At this very moment, the billions of neurons in your brain are using their trillions of connections to enable you to read and comprehend this sentence. Now, by studying the neurons involved in the sense of smell, researchers from Kyushu University's Faculty of Medical Sciences report a new mechanism behind the biomolecular bonsai that selectively strengthens these connections. How neuronal circuits remodel themselves over time, especially during early development, is an open question in neurobiology. At the start of neuronal development, neurons form excessive amounts of connections ...

Melting High Mountain Asia glaciers are revealed as a potential source of greenhouse gases

Melting High Mountain Asia glaciers are revealed as a potential source of greenhouse gases
2021-07-15
The cryosphere, a term used to describe the areas of the Earth's surface where water exists in solid form, plays an important role in regulating the Earth's climate. Due to cryospheric retreat; for example, the melting Greenland ice sheet in the Arctic, greenhouse gases that were formerly in "frozen storage" are now being released. High Mountain Asia, also known as the Tibetan Plateau, hosts the largest volume of glaciers outside the polar regions. However, Tibetan glaciers are currently excluded from global greenhouse gas budgets. According to Shichang Kang, leader of a group of researchers who recently became the first team to measure the flux variations of greenhouse gases (CO2 and CH4) in typical glacial basins in High Mountain Asia, it's important that Tibetan glaciers are not ...

Study IDs risk factors for irregular heartbeats in hypertrophic cardiomyopathy patients

Study IDs risk factors for irregular heartbeats in hypertrophic cardiomyopathy patients
2021-07-15
New research will help doctors identify, treat and prevent potentially dangerous irregular heartbeats in patients with hypertrophic cardiomyopathy (HCM), a common heart condition in which the heart thickens and strains to pump blood. These chaotic heart rhythms are known as atrial fibrillation. Atrial fibrillation can be asymptomatic, but it can lead to blood clots, stroke or even heart failure. The new research, from an international team of doctors and scientists, identifies risk factors for major atrial fibrillation outcomes, such as the need for procedures or hospitalization for more than 24 ...

A rapid method to quantify antibodies against SARS-CoV-2

A rapid method to quantify antibodies against SARS-CoV-2
2021-07-15
Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines. In the 18 months since the emergence of Covid-19 pandemic, great strides have been made in discovering and inventing various approaches to track and control the spread of the SARS-CoV-2 virus. Rapid and accurate diagnosis has always been vital in this regard. The gold standard since the beginning of the pandemic has been the RT-PCR method; however, it is time-consuming, labor-intensive, and requires sophisticated ...

The cells combating a deadly lung disease

The cells combating a deadly lung disease
2021-07-15
Single-cell RNA sequencing has revealed a subset of cells that could provide protection from a rare, but severely debilitating and fatal, lung disease. The findings were published by Nagoya University researchers and colleagues in the European Respiratory Journal. Further research could lead to new therapeutic strategies for the disease, called idiopathic pulmonary fibrosis (IPF). Approximately 15 in every 100,000 people worldwide develop IPF. Its prognosis and five-year survival rate can be worse than many types of cancer. It involves the development of scar tissue on the lung, impairing gas exchange and making ...

Looking beyond the numbers to see pandemic's effect on nursing home residents

Looking beyond the numbers to see pandemics effect on nursing home residents
2021-07-15
INDIANAPOLIS -- Nursing homes throughout the United States have been devastated by the COVID-19 pandemic with many perceptions and misperceptions but little documentation about what has happened on a day-by -day basis to residents in these facilities. A study from Regenstrief Institute and Indiana University School of Medicine research scientists is one of the first to describe and identify patterns in the course of COVID-19 in the typically frail individuals who reside in nursing homes. Much has been written about number of deaths, vaccine uptake and ...

Silicon in drinking water caused irreversible lung pathologies in rodents

2021-07-15
Bone density, skin and hair health, and the mobility of joints depend to a great extent on the microelement of silicon. We mostly get it with food, but silicon is also consumed with some biologically active additives that promise beauty, longevity, and youth. The element can also be found in drinking water of a natural origin: usually, it is included in the compound of sodium salt and metasiliconic acid. However, in the case of microelements, one should be extremely careful: a deficiency could lead to diseases, but an overdose could bring negative effects too. Together with colleagues from the Chuvash State University and the Hamburg Medical University, scientists of Immanuel Kant Baltic Federal University studied the effect of prolonged silicon consumption in relatively ...
