Healthy land
Land has a wide variety of uses: agricultural, residential, industrial, and recreational. Microbes play a key role in the terrestrial ecosystem, providing symbiotic relationships with plants. Human use of land has led to the exhaustion of nutrients in soils, contamination of land, and a reduction in biodiversity. Applying our knowledge of microbes will be essential in restoring the biodiversity of affected ecosystems. Greater research into how microbes impact human life on land could all have a positive impact, by increasing crop production, repurposing areas of land and improving microbial biodiversity in soil, land, and water.

Pros and cons of pesticides and fertilizers in real-world mandarin orange farms
Researchers examined how different kinds of pesticides and fertilizers affect mandarin oranges across Japan. Advanced statistical analysis showed that while reducing pesticides enhanced the diversity of microbes in the soil, it also led to an increase in fruit disease caused by leaf pathogens.

NewsMachine learning reveals how to maximize biochar yield from algae
Researchers have developed a powerful machine learning framework that can accurately predict and optimize biochar production from algae, offering a faster and more sustainable path toward carbon rich materials for climate mitigation, soil improvement, and environmental applications.
NewsCultivated peanut AhPR10 gene family mediates resistance to Aspergillus flavus
Researchers identified and analyzed PR10 genes in cultivated peanut (Arachis hypogaea L.), and found three genes that demonstrated potential importance in peanut resistance to Aspergillus flavus.
NewsMineral dust accelerating melting of Greenland ice sheet
Scientists have found that airborne mineral dust and other aerosols are directly connected to how much algae grows on the ice. The algae interfere with albedo, or the reflection of the sun’s rays, exacerbating melting.

Scientists say these two viruses may become the next public health threats
Two emerging pathogens with animal origins — influenza D virus and canine coronavirus — have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among humans.
NewsPesticides significantly affect soil life and biodiversity
Seventy per cent of soils in Europe are contaminated with pesticides. A Europe-wide study shows that their effects on soil life are substantial, as pesticides suppress various beneficial soil organisms. To protect soil biodiversity, the findings should be taken into account in current pesticide regulations.
NewsScientists use AI to uncover the secret lives of fungi
Scientists have developed an automated workflow that assesses scientific abstracts and accurately identifies whether a fungus has a single lifestyle or a dual, flexible one. Understanding this flexibility is vital for predicting how forests and farms will react to climate change.
NewsFungus unlocks hidden phosphorus from massive industrial waste
Researchers have shown that Aspergillus niger can extract large amounts of residual phosphorus from phosphogypsum, a byproduct of phosphoric acid production that is generated in enormous quantities worldwide. More than 40 per cent of the phosphorus locked inside this waste material can be recovered.
NewsIn polar regions, microbes are influencing climate change as frozen ecosystems thaw, review finds
Microbes across Earth’s coldest regions are becoming more active as glaciers, permafrost and sea ice thaw, accelerating carbon release and potentially amplifying climate change, according to a new international review.
NewsNative fungi from almond orchards show promise as sustainable defenders against a devastating crop disease
Researchers report that naturally occurring fungi found on and within almond trees can strongly suppress Colletotrichum godetiae, the primary cause of almond anthracnose in the Mediterranean Basin.
NewsFirst known lichen in the fossil record helped structure terrestrial ecosystems
A group of researchers has confirmed the identity of the first lichens to inhabit Earth, Spongiophyton, around 410 million years ago, in great detail for the first time. The study confirms that the symbiosis between fungi and algae that dissolves rocks helped form the first soils.
NewsPlants can be designed to alert us to harmful chemicals and diseases
A collaborative team of researchers have developed groundbreaking tools that allow grasses—including major grain crops like corn—to act as living biosensors capable of detecting minute amounts of chemicals in the field.
NewsNaval Research Lab Space Station study reveals key challenges and opportunities for microbial biomanufacturing in space
Scientists have completed a spaceflight biology investigation aboard the International Space Station (ISS) that reveals how microgravity fundamentally alters microbial metabolism, limiting the efficiency of biological manufacturing processes critical to future long-duration space missions.
NewsStudy sheds new light on what drives evolution of gut microbiomes
A study of wild African herbivores offers new insight into how environmental conditions – not just diet and anatomy – can influence the evolution of gut microbes that play a critical role in animal health and well-being.
NewsEpigenetic switch strengthens plant immunity against downy mildew
Researchers investigating how epigenetic regulators influence resistance to downy mildew in Brassica rapa identified BrHDA6 as a positive regulator of disease resistance and demonstrated that it enhances immunity by modifying a key enzyme in salicylic acid metabolism.
NewsTracking antibiotic resistance in the environment gets a high tech upgrade
Antibiotic resistance is often framed as a hospital problem, but a growing body of evidence shows that the environment plays an equally critical role in the global spread of drug resistant bacteria. Rivers, soils, wastewater, and even the air can act as reservoirs for antibiotic resistance genes that may eventually ...
