Study finds that active ionisation of air reduces noise

Did you know that by ionising the air with wires, you could make a loudspeaker? Simply put, creating an electric field strong enough to ionise the air molecules in a network of parallel wires or a plasma transducer can result in the production of sound. The charged ions are then driven along the magnetic field lines, pushing the remaining non-ionized air in a manner that generates sound.

Ways to advance goals of equity and justice in climate action planning: Study

Researchers discovered that while equity and justice are frequently listed as goals in municipal climate action plans, the discussion of these concepts is mostly rhetorical. A new study from the University of Waterloo outlined how planners can bridge the gap and address the current state of climate change and social injustice.

Study finds reduced emissions during epidemic aggravated climate change

Researchers discovered that Covid epidemic shutdowns in South Asia significantly reduced the number of short-lived cooling particles in the air while having no effect on the concentration of long-lived greenhouse gases. Researchers were thus able to demonstrate how lower air pollution emissions lead to cleaner air but also to faster global warming.

Cutting boards may create microparticles when chopping veggies: Study

Cutting carrots on wood and plastic boards, according to the study, can generate tens of millions of microparticles each year. However, a toxicity test found that polyethylene or wood microparticles generated during chopping had no effect on mouse cell survival.

Memory killer cells may improve melanoma patients' chances of survival: Study

Long-lasting killer cells are present in our skin and act as a defence against intruders. Researchers from Denmark's University of Copenhagen and Sweden's Karolinska Institutet have now discovered how these cells are formed and demonstrated that higher concentrations of memory killer cells in tumour tissue are associated with a higher survival probability for melanoma patients. The work was published in the journal Immunity.

Study reveals how grief increases risk of heart problems

The loss of a loved one may have a profound impact on both mental and physical health. The University of Arizona investigated the impact of sadness on heart function and concluded that acute grief might cause a considerable rise in blood pressure. Grief, according to the findings, may be a risk factor for cardiac events.

Managing asymptomatic high blood pressure associated with cardiac, kidney injury: Study

Blood pressure is frequently measured in hospitalised patients. Severe hypertension can result in a heart attack, stroke, or damage to blood vessels and organs such the heart, brain, kidneys, and eyes. The majority of hospitalised patients, on the other hand, have transiently elevated blood pressure without signs of organ damage, which is known as silent hypertension and is infrequently treated with blood pressure medications. However, there is little data to guide such treatment decisions.

Researchers suggest detection tool for beech leaf disease's nematode pest

Beech leaf disease is a new threat to the ecosystems of North American woods. Since its discovery in northern Ohio in 2012, it has spread to twelve other US states and Canadian provinces. The damaged and dying trees were first identified only on the basis of their symptoms, which included black banding along the leaf veins and shrivelled, leathery leaves.

Study reveals possible target for treating neuropsychiatric disorders in teens

Throughout development and adolescence, the brain is constantly changing. Neuropsychiatric illnesses, such as schizophrenia, frequently emerge in early adulthood. During this stage of development, the dopamine system, which is required for cognitive processing and decision-making, begins to fail.

Study finds how Immunotherapy for brain cancer metastases displays clinical benefit

Researchers discovered that 42 percent of patients with metastatic brain cancer benefited from the immune checkpoint inhibitor pembrolizumab in a phase 2 clinical study, with seven patients living for more than two years. The authors emphasise that these advantages must be balanced against the potential of toxicity, but the study's overall findings encourage additional research and attempts to identify individuals who are most likely to benefit from this medication
