Phys.org / A geometric recipe for stabilizing atomically thin metals
Metallenes are atomically thin metals whose unique properties make them extremely promising for nanoscale applications. However, their extreme thinness makes them also flimsy.
Phys.org / Parasitic fungus may have emerged 18 million years before the ants with which it lives today
A genus of fungi previously considered a parasite of fungi associated with ants may actually have much more complex ecological functions. According to a study published in the journal Communications Biology, one piece of ...
Phys.org / Plant-virus proteins guide gold nanoparticles into eco-friendly sheets for solar tech
Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles' optical properties. ...
Phys.org / Hydrogel switches from liquid to gel at body temperature, enabling easy removal
What if a doctor could inject an electricity-conducting liquid into the body, let it temporarily solidify to record nerve signals or jump-start healing, and then return it to liquid form for easy removal?
Phys.org / New model describes how reaction-diffusion networks develop 'foams'
For numerous fundamental processes of life, the formation of certain protein patterns is essential. Protein pattern formation controlled by molecular switches is—like many processes in nature—far removed from a state ...
Phys.org / Towards sustainable organic synthesis—mechanochemistry replaces lithium with sodium in organic reactions
Highly reactive organometallic reagents, like organolithiums (molecules with a carbon–lithium bond) are essential reagents in organic synthesis because of their applications from polymer synthesis to pharmaceuticals, and ...
Phys.org / Estimating the number of flying insects in the US using weather radar
Although millions upon millions of living creatures fly, feed and reproduce in the air, this habitat has hardly been researched. Insects are under increasing pressure worldwide due to global change and human activities. However, ...
Phys.org / Global shift to sustainable pest management expected to yield long-term benefits
What would happen if farmers around the globe were to switch over to sustainable pest management? An international study headed by the University of Bonn and ETH Zurich focused on precisely this question. The study is based ...
Phys.org / When climate risk hits home, people listen: Local details can enhance disaster preparedness messaging
A subtle change in how climate risk is communicated—mentioning a person's local area—can significantly increase attention to disaster preparedness messages, according to a new study by researchers at the Stockholm School ...
Phys.org / Bacterium's molecular speargun defense may leave it exposed to antibiotics
Countless bacterial species share cramped environments where competition for space and resources is fierce. Some rely on a molecular speargun to outcompete their opponents. One of them is Pseudomonas aeruginosa. It is widespread ...
Phys.org / An ancient genetic switch that lets plants grow, adapt and survive
A team of scientists from Monash University has identified a single gene in a land plant that could help explain how plants first evolved the ability to grow continuously, a key trait that allowed them to colonize dry land ...
Phys.org / When companies 'go green,' air quality impacts can vary dramatically
Many organizations are taking actions to shrink their carbon footprint, such as purchasing electricity from renewable sources or reducing air travel. Both actions would cut greenhouse gas emissions, but which offers greater ...
