Nitric oxide overload jams plant immune signals, researchers find
Nitric oxide overload jams plant immune signals, researchers find Gaby Clark Scientific Editor Robert Egan Associate Editor A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings. Plants do not have blood, nerves or immune cells like people do, but they still have ways to protect themselves. When one leaf is attacked by a pathogen, the plant can send warning signals to...
Bacteria can learn and form memories without a brain
Bacteria can learn and form memories without a brain Lisa Lock Scientific Editor Robert Egan Associate Editor Researchers at Carnegie Mellon University have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments, all without a brain or nervous system. The research could shape how scientists think about bacterial infections and antibiotic treatment. In a study published in PRX Life, researchers from Carnegie...

Plants could be used to grow medicines in space, study shows
Plants could be used to grow medicines in space, study shows Lisa Lock Scientific Editor Robert Egan Associate Editor Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste. The...
Mitochondria directly interact with the nuclear pore complex
Abstract Mitochondria regulate cellular processes through direct and indirect interactions with other organelles. A well-studied example has been contact with the endoplasmic reticulum at mitochondrial-associated endoplasmic reticulum membranes1, which control pathways including redox and calcium homeostasis2,3. Recent studies have also reported direct mitochondria–nuclear membrane contacts in cancer cells and yeast that promote pro-survival signalling4,5.
Algal blooms explained: How scientists are helping spot them sooner
Algal blooms explained: How scientists are helping spot them sooner Lisa Lock Scientific Editor Andrew Zinin Lead Editor Algal blooms can seem to appear overnight. A stretch of ocean that looked clear days earlier can suddenly appear discolored and sometimes pose risks to ecosystems and human health. But scientists say blooms are rarely sudden—understanding what happens before they appear is key to managing them.
The Sorghum Lipid Database (SoLD): population-scale lipidomics linking environmental and genetic variation in the Sorghum Association Panel
Sorghum (Sorghum bicolor ) is a climate-resilient crop whose acclimation to nutrient limitation and low temperature likely involves extensive lipidome reconfiguration. Lipids are key membrane components, carbon and energy stores, and mediators of stress signaling, yet population-scale lipidomics data for sorghum are limited. We present the Sorghum Lipid Database (SoLD), a curated lipidomics resource from the Sorghum Association Panel grown under two field regimes: (i) a nutrient-sufficient...
Integrating citizen science with experimental data uncovers how switchgrass adapts flowering by region
Integrating citizen science with experimental data uncovers how switchgrass adapts flowering by region Gaby Clark Scientific Editor Robert Egan Associate Editor In its native habitat, switchgrass flowered earlier when growing farther north. In experiments with diverse genetic samples, it flowered earlier in the south. The discrepancy wasn't a welcome sight for a research team studying how prairie grasses respond in different environments, but resolving the apparent conflict led the...
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals Stephanie Baum Scientific Editor Robert Egan Associate Editor What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats.
