Breathing alien air: the search for biosignatures on exoplanets
Among the most promising indicators of biogenic elements are volatile organic compounds produced by life forms. The detection of specific metabolites such as dimethyl sulphide (DMS) and related compounds may hint at extraterrestrial biology.
Enhancing Nigerian fermented foods for nutrition, health and sustainability
Fermented foods are integral to Nigerian cuisine and culture, providing sustenance, health benefits, and cultural heritage. These foods owe their unique flavours, textures, and health benefits to fermentation, a process driven by a diverse community of microorganisms, including bacteria, yeasts, and moulds.

Could livestock-originated probiotics replace synthetic antibiotics for livestock?
In many developing countries, the use of antibiotics in both humans and animals is often indiscriminate and poorly regulated. Could livestock-originated probiotics be a suitable replacement?
Key lessons from the saMBA studies on human gut microbiome diversity
A recent study published in Nature Communications introduced the South American MicroBiome Archive (saMBA). The study offers several critical insights that deserve careful consideration.

Gut microbiome affects alcohol preference by influencing brain’s reward system
A new study shows how an overgrowth of Candida albicans - overly abundant in people with alcohol use disorder - increases levels of inflammatory molecules that can cross the blood-brain barrier and affect the desire for alcohol.
A triple-threat iron supplement that also improves gut health
A new iron supplement combines iron, prebiotics and probiotics. In trials, the treatment successfully restored blood iron levels in anemic mice without initiating an inflammatory response or throwing off the balance of the gut microbiota.
Research alert: Bacterial chatter slows wound healing
Researchers have discovered a previously unrecognized mechanism by which Staphylococcus aureus delays wound healing. The study finds that quorum sensing is a key driver of delayed healing in wounds infected by S. aureus.

Algae and water fleas in lakes: Light color influences food webs
Phytoplankton are the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.
What we know and what we need to know about Antarctic marine viruses
Antarctic marine viruses, while proven to be important players in the ecosystem, are not completely understood. In a new paper, researchers aim to fill in the gap between what is known and what is unknown, with a primary focus on RNA viruses, the influence of climate change and their implications.
