NewsDesert soils emit greenhouse gases in minutes — even without live microbes
A groundbreaking study reveals that desert soils can emit powerful greenhouse gases within minutes of being wetted—even in the absence of microbial life. It challenges long-standing assumptions that soil microbes are solely responsible for post-rain “pulse emissions” of gases like carbon dioxide (CO₂), nitrous oxide (N₂O), and nitric oxide (NO).

NewsPretreatment methods deploying microbes bring second-gen biofuels from oilcane closer to commercialization
In collaboration with other Bioenergy Research Centers (BRCs), researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) are developing industrially feasible techniques for second-generation biofuel production from oilcane, an oil-rich variety of sugarcane, to help meet our growing societal demand for fuels.

NewsBacteria rewire digestive systems to turn plant waste into power
A new study shows that Pseudomonas putida, a common soil bacterium, completely reorganizes its metabolism to thrive on complex carbons from lignin. By slowing down some metabolic pathways while accelerating others, the bacterium manages to extract energy from lignin without exhausting itself.

NewsEnvironmental antibiotic resistance unevenly addressed despite growing global risk, study finds
Antibiotic resistance in the environment is a growing and largely overlooked crisis receiving inconsistent attention, according to a new study. Worryingly few studies have explored how antibiotic resistance spreads in the air, oceans or green spaces.

NewsAP2-domain transcription factor WRI5a-regulated MtABCB1 promotes arbuscule development in mycorrhizal symbiosis
A new study of arbuscular mycorrhizal (AM) symbiosis suggests that the MtABCB1 gene likely influences arbuscule development by modulating the distribution and homeostasis of auxin within symbiotic cells.
