An international research team led by The University of Osaka has demonstrated that two-faced Janus nanoparticles can restore the effectiveness of antibiotics against drug-resistant bacteria. These particles disrupt the protective outer membrane of Gram-negative bacteria, which normally blocks antibiotics. This allows conventional drugs to regain access and kill the once-resistant microbes. This synergistic strategy restores the effectiveness of existing antibiotics, offering a new line of defense against the growing threat of superbugs and extending the utility of our current medical arsenal.

Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato and a wide range of other crops, according to new research. The work comes from an unusual collaboration between plant pathologists and engineers at UC Davis. 

The lower atmosphere, or troposphere, may be the largest habitat on the planet. A study published in Ecology argues that this vast aerial expanse is an environment teeming with life.  

Important everyday products—from plastics to detergents—are made through chemical reactions that mostly use precious metals such as platinum as catalysts. Newly identified methods to harness the properties of tungsten carbide could yield viable substitutes for platinum.

People have long said that “bread is life.” Now, researchers at Tufts University are using the bubbling mixtures of flour and water known as sourdough starters to explore what shapes life at the microscopic level. Their findings, published in Ecology, demonstrate a simple way to predict how microbial species will live together, providing insights that could inform baking, food safety, and human health.

For 450 million years, plants and soil fungi have been trading partners. The fungi weave through plant roots, delivering phosphorus and other soil minerals in exchange for sugars and fats produced by the plant through photosynthesis. This ancient collaboration supports roughly 80% of Earth's plant species—including corn, wheat, and other crops that feed billions of people. Now, a team from the Boyce Thompson Institute (BTI), led by Professor Maria Harrison, has coupled two powerful tools that allow scientists to identify which proteins work together to make these partnerships function—and to verify those interactions in living plant roots, where the collaboration actually occurs.

Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams (FRIB) and current postdoctoral fellow at the University of Regina in Canada, the study presents the first rare isotope beam measurement of proton capture on arsenic-73 to produce selenium-74, providing new constraints on how the lightest p-nucleus is formed and destroyed in the cosmos. The team published its results in Physical Review Letters (“Constraining the Synthesis of the Lightest 𝑝 Nucleus ⁷⁴Se”).

A new study from UC San Diego’s Scripps Institution of Oceanography finds that marine microbes had mostly positive interactions with one another during a six-year study. These positive interactions became even more common during times of environmental stress.
