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 / 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 ...
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 / Helping crops survive in saltwater: Mangroves reveal key cellular traits
Rising sea levels along coastlines not only threaten populations, but also pose a danger to agricultural crops, which may be damaged by surging amounts of saltwater. Researchers have, in response, sought to improve salt-tolerance ...
Phys.org / Shining a spotlight on polyploid cells: New tool uncovers spatial patterns of DNA content across tissues
A collaborative effort by the Formosa-Jordan lab from the Max Planck Institute for Plant Breeding Research in Cologne, Germany, the Fox lab from Duke University, U.S., and the Roeder lab from Cornell University, U.S., developed ...
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 / Novel compound attacks tuberculosis bacteria's ATP synthase, showing promise against drug resistance
Researchers at Martin Luther University Halle-Wittenberg (MLU) have developed a promising new substance for targeting bacteria that cause tuberculosis. The team have produced a compound that inhibits the pathogens' ability ...
Phys.org / Greenhouse gases projected to sharply increase extreme flooding in Central Himalayas
Rising greenhouse gas emissions could see the size of extreme floods in the Central Himalayas increase by between as much as 73% and 84% by the end of this century.
Phys.org / DNA nanostructures get an ionic 'protective suit' for harsh biological environments
DNA nanostructures are exciting new biomedical tools with myriad potential in treatment, diagnosis and disease prevention. Made of folded DNA, these nanostructures are highly programmable and have been used in bioengineering ...
Phys.org / Unexpected protein fold links bacteria, viruses, and eukaryotes in DNA management
An investigation into cellular components in bacteria has unexpectedly uncovered a feature with relevance across many life forms, paving the way for diverse research, biotechnical and medical applications.
Phys.org / AI maps gene redundancies to guide crop improvement
As global temperatures rise, Cold Spring Harbor Laboratory (CSHL) scientists work to grow stronger, more resilient crops. Yet, this process is challenging. Plants often have several related genes that control desirable traits, ...
Phys.org / Temporary carbon removals can offset methane's short-term warming impact
Carbon removal projects could prove vital in offsetting methane emissions—the second largest contributor to global warming.
