NASA satellites reveal major ocean nutrient stress
NASA satellites reveal major ocean nutrient stress Lisa Lock Scientific Editor Robert Egan Associate Editor A new study combining NASA satellite observations, ocean surveys and genetic testing of marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. The researchers report that this nutrient stress affects microscopic marine organisms and could influence marine ecosystems over time. The research, published June 5...
Help lower blood pressure by eating supermarket fruit rich in 'important' nutrient
Help lower blood pressure by eating supermarket fruit rich in 'important' nutrient Studies suggest the fruit may support healthy blood pressure levels Consuming a diverse range of fruit and vegetables benefits our health, and the greater variety of plants you eat, the more nutrients you'll absorb and the healthier your gut microbiome will become. Some experts recommend aiming for 30 different plants weekly. While most of us have understood the significance of vitamins since childhood,...
Nutrient-responsive and DAF-16/FoxO target H1 histone HIL-1 promotes resistance to starvation and bacterial pathogens in Caenorhabditis elegans
Insulin/IGF-1 signaling (IIS) mediates metabolic and developmental acclimation to stressful conditions including starvation. The transcription factor DAF-16/FoxO actuates many of the physiological effects of reduced IIS, yet the specific contributions of DAF-16 target genes to stress resistance remain poorly understood. We explore the function of C. elegans H1 linker histone HIL-1/H1.0, a DAF-16 target that is upregulated during starvation.
World's healthiest vegetable named by scientists — it's in every supermarket
World's healthiest vegetable named by scientists — it's in every supermarket You can easily pick up this vegetable in any supermarket — it's not expensive Scientists have compiled a list of the most nutrient-dense vegetables on the planet — and one comes out at the very top. A study published by the Centers for Disease Control and Prevention (CDC) sought to rank vegetables based on the nutrients they contain and the density with which those nutrients are found. Only one vegetable scored a...
How gene swapping helped build the planet's decomposers
How gene swapping helped build the planet's decomposers Sadie Harley Scientific Editor Alexander Pol Deputy Editor Decomposers are crucial for keeping Earth habitable, breaking down dead biomass and returning key nutrients, such as carbon, nitrogen and phosphorus, to the ecosystem. Most decomposers, including fungi, survive through osmotrophy—a means of feeding by absorbing dissolved nutrients rather than engulfing prey. But how this method of feeding repeatedly arose across the eukaryotic...
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...
NutriMLLM: Multimodal Large Language Models for Dietary Micronutrient Analysis
arXiv:2606.08948v1 Announce Type: new Abstract: Comprehensive estimation of dietary micronutrients from food images could improve clinical nutrition care, but training such models requires large multimodal datasets linking diverse foods to complete nutrient profiles. We first show that existing multimodal large language models (MLLMs), including leading proprietary models, are unreliable for this task. Across five model families and four independent evaluation benchmarks (ASA24, SNAPMe,...
Inorganic sulfate transport by the Mycobacterium tuberculosis PE22/PPE36 complex
Mycobacterium tuberculosis (Mtb) encodes two multigene families with 169 members that are exclusive to mycobacteria, the pe and ppe genes. These genes have unusual sequences including low-complexity repeat regions, but their functions and whether they share a common function have long been unclear. Recently, several members of the pe/ppe family were shown to transport nutrients across the outer Mtb membrane, a role for which no other proteins have yet been identified.
Queen Elizabeth II's daily breakfast that may have been secret to living to 96
Queen Elizabeth II's daily breakfast that may have been secret to living to 96 The late monarch's first meal of the day was surprisingly simple, but experts say it contained nutrients linked to healthy ageing Queen Elizabeth II enjoyed some of the finest food available during her 70-year reign, but one meal she reportedly kept remarkably simple was breakfast. The late monarch, who became Britain's longest-serving sovereign before her death aged 96 in September 2022, is understood to have...
Compartment-Specific Assembly and Functional Potential of the Bacteriome of Citrullus colocynthis in a Semi-Arid Ecosystem
Plants inhabitng in arid and semi-arid ecosystems, such as Citrullus colocynthis (L.) Schrad., are adapted to drought, heat, salinity, and nutrient limitation. Their associated microbial communities may further support plant persistence under these harsh conditions. Here, we characterized the bacterial communities associated with leaf endosphere, rhizosphere and roots of C. colocynthis growing in a semi-arid region of Moroccan using 16S rRNA gene amplicon sequencing, culture-dependent...
