Showing results in Iceland’s volcano eruption could reveal aerosols’ climate change effect

News

A ‘natural experiment’ provided by the six-month eruption of the volcano Holuhraun in Iceland may help to constrain uncertainties surrounding the impact of anthropogenic aerosols on climate.
Researchers at the University of Exeter studied the plume of the eruption, which produced more sulphur dioxide than all 28 EU countries’ anthropogenic emissions combined over the eruption period, using satellite imagery and via climate system modelling.

Antibiotic resistance is a growing problem and a major threat to health worldwide, especially in ‘gram-negative’ bacteria which have two cell membranes. Developments in targeted drug delivery for cancer treatment, involving ‘tandem peptides’, which act first to allow drugs to pass bacterial membranes before the active agent kills tumour cells, have been adapted by MIT researchers to effectively treat bacterial infection by Pseudomonas aeruginosa, a bacterium which can cause pneumonia, in the lungs of mice.

Thank you to everyone for attending Aerosol Society Focus Meeting 10 – Bioaerosols, at the University of Bristol on the 8th of June 2017. Over 50 delegates gathered to network and share research from 18 speaker presentations, headlined by Rob Kinnersley from the Environment Agency and supported by product demonstrations from Biral and Air Monitors.

A team of independent reviewers appraised our junior scientist presentations throughout the day and we were delighted to present the awards for the most outstanding junior scientist presentations, sponsored by Atmosphere, to……

A study conducted in children and young adults in Mexico City has shown the presence of combustion-derived nanoparticles in samples of brain tissue obtained at autopsy and cerebrospinal fluid sampled during medical procedures, with those from Mexico City having higher concentrations than those in other, smaller less polluted, cities in Mexico.

A review of ‘equine asthma’, a term covering a range of respiratory diseases in horses, suggested that the recent rise in recorded veterinary incidence and severity may be due to increased time spent indoors, in enclosed stables and riding arenas, where airborne dust concentrations are high.

Although mechanisms regarding harmful action of inhaled ultrafine particles are becoming better understood, a major knowledge gap is the question of whether there is direct impact from inhaled nanoparticle translocation into the bloodstream.
