New high-resolution structures of the bacterial ribosome determined by researchers at the University of Illinois Chicago show that a single water molecule may be the cause-and possible solution-of antibiotic resistance.

Large-scale irrigation infrastructure projects are back on the development agenda in sub-Saharan Africa after a near 30-year hiatus, despite projects having had disappointing results, with social and environmental side effects outweighing benefits. Such projects are planned in response to water scarcity pressures and are seen as a solution to intensify agricultural production, support rural economic development and enhance resilience to climate change.

Natural hazard events, such as storms, floods, and wildfires, entail huge and growing costs all over the world, but they can also be occasions for countries to implement risk-reducing changes. There is no research consensus on whether natural hazard events lead to policy modifications or, instead, contribute to stability and preservation of existing solutions. Knowledge in this area to date has been based on individual case studies, and global trends have not been studied.

In fact masks (and faceshields) supplemented with constraints of superspreader events can save us trillions of dollars in future lockdowns (and lawsuits) and be potentially sufficient (under adequate compliance) to stem the pandemic. Bureaucrats do not like simple solutions.

]. "The narrow strip of soil around the plant's root teems with millions of microorganisms, making it one of the most complex ecosystems on earth. To determine whether the composition of this "root microbiome" triggers changes within the plant, postdoctoral fellow Dr. Elisa Korenblum and other members of a team headed by Prof. Asaph Aharoni of Weizmann's Plant and Environmental Sciences Department, created a hydroponic set-up in which they split the roots of tomato seedlings in two. In a series of experiments, the researchers placed one side of the split roots in vials, progressively diluting the soil suspensions several times. Each dilution altered the soil's microbial composition and reduced the diversity within the microbial community, so that the different suspensions ended up containing root microbiomes with high, medium and low diversity levels. The other side of the roots was submerged in a vial with a clean, soil-free solution. If the soil microbes communicate with the plant, one would expect to detect signs of their messages on both sides of the root system. That was exactly what the scientists found…. 'Our ultimate goal is to decipher the chemical language - one could call it 'Plantish' - used by plants and the soil to interact with one another,' Korenblum
