Nowadays, the maintenance of wellbore stability is a very important activity in the drilling industry. Wellbore stability can be improved by designing proper drilling fluid.
Some bacteria can release toxins that provoke their neighbours into attacking each other, a tactic that could be exploited to fight infections.
Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.
Nerve agents are scary stuff. They are among the most deadly substances on earth, yet can be odorless, tasteless and difficult to detect. But researchers now report in ACS Central Science that they have adapted building materials normally associated with children's toys and a cell phone to help sense these compounds. The new method can sensitively detect these poisons, quantify the amount and distinguish between different classes present at contaminated sites.
Milk in parts of Ukraine has radioactivity levels up to five times over the country's official safe limit, new research shows.
New research from the University of East Anglia joins the dots between zombie ants, an insect-world arms race and the search for new antibiotics. Scientists probing one of the mysteries of the insect world identified a powerful chemical weapon used in the arms race between fungus-farming leafcutter ants and the parasites that plague them. It is hoped that the findings will help scientists search for new antibiotics from this unique battlefield.
A major new study appearing in PLOS Biology on May 31 examines more than a century of fungal pathogens, finding well-aimed biosecurity measures cut the spread of unwanted fungi into a nation, even in the face of increased globalized trade.
A potential global catastrophic risk-level pandemic pathogen will most likely have a respiratory mode of transmission; be contagious during the incubation period, prior to symptom development, or when infected individuals show only mild symptoms; and need specific host population factors (e.g., immunologically naïve persons) and additional intrinsic microbial pathogenicity characteristics (e.g., a low but significant case fatality rate) that together substantially increase disease spread and infection. RNA viruses are the biggest threat.
Mortality rates were higher during the nine months of military liberation of Mosul, Iraq, than during the 29 months of exclusive Islamic State of Iraq and Syria (ISIS) control, according to a study published this week in PLOS Medicine. The population-based survey demonstrated that high mortality rates resulted from the military offensive despite the use of modern precision-targeted ordnance.
The contribution of economic, social and cultural rights to sustaining global peace is largely overlooked within new developments to tackle violent conflict, says new research led by Lancaster University.
