Identification of active deubiquitinases in dendritic cells under unstimulated and activated conditions.

13/10/2026 - Ubiquitination is a post-translational modification with well described roles in the regulation of immune cell function, such as dendritic cells (DCs). DCs are crucial initiators and regulators of T...

Your gut bacteria could be changing how many calories you absorb

12/10/2026 - Scientists have developed a model showing that gut bacteria play a surprisingly important role in how many calories we absorb, meaning food labels may not tell the full story. In a controlled study,...

Unraveling phenotypic variation in multiscale behavioral dynamics

11/10/2026 - Behavioral variability reflects differences in internal and external parameters and provides a substrate for natural selection. However, uncovering its structure is challenging because behavior...

Spatiotemporal Autocorrelation of Acoustic Indices: Implications for Biodiversity Monitoring

11/10/2026 - Passive acoustic monitoring (PAM) is increasingly applied in biodiversity research, yet the spatiotemporal dependence inherent in acoustic indices remains poorly understood, limiting their...

Neanderthals may have used prehistoric glue as an ancient antibiotic

10/10/2026 - Neanderthals may have used a sticky substance made from birch bark to treat wounds thousands of years before antibiotics existed. Researchers recreated ancient birch tar production techniques and...

Scientists discover why a 100-year-old mushroom disease won't go away

11/10/2026 - Scientists have uncovered a surprising secret behind a mushroom disease that has frustrated growers for more than a century: It involves more than 17 species of harmful bacteria, not just one. The...

Record El Niño threatens Great Barrier Reef with ecological shift

08/10/2026 - Researchers are worried about the impact the strongest-known El Niño will have on the Great Barrier Reef, and whether anything can be done to avert the World Heritage Area’s demise

Bacterial Mercury Resistance Reveals a Robust Species-Structured Human Antimicrobial Mobilome

07/10/2026 - Antimicrobial resistance (AMR) is increasingly recognised as an ecological and evolutionary phenomenon that extends beyond clinical environments. Despite the predominant focus on antibiotics,...

Revealed: how this common gut microbe protects against heart disease

Scientists warn a popular vitamin D supplement may have a hidden downside

08/10/2026 - Not all vitamin D supplements are created equal, and new research suggests that one popular form may have an unexpected downside. Scientists found that taking vitamin D2 can actually lower the...

Taking antibiotics? Sugar may be making the damage worse

07/10/2026 - Eating more sugar while taking antibiotics was linked to greater disruption of the gut microbiome and increased growth of potentially harmful bacteria. Researchers say temporarily cutting back on...

Convergent and divergent patterns of holobiont evolution in co-distributed chemosynthetic symbioses

06/10/2026 - Intraspecific variation in microbial symbioses is shaped by a variety of ecological and evolutionary processes. In geographically separated populations, divergence in genomic traits is expected due...

Host Cell Wall Polysaccharides Modulate Nanosynbacteria Recognition and Attachment

06/10/2026 - Ultrasmall episymbiotic bacteria grow on the surface of their obligate bacterial hosts. These episymbionts have a restricted host range and likely rely on host-derived receptor molecules to identify...

An Expanded Lpt Pathway Couples Surface Lipoprotein Export to Outer Membrane Vesicle Biogenesis in Bacteroides

05/10/2026 - The ecological dominance of Bacteroidota in the human gut microbiota derives from their exceptional capacity to metabolize diverse dietary and host-derived glycans. This ability relies on...

Community-wide adaptive evolution of gut bacteria during dietary transitions

04/10/2026 - Diet exerts selection on bacterial species within the mammalian gut microbiota1,2,3,4,5, but the extent, modes, genomic bases, and repeatability of gut bacterial adaptive evolution in response to...

Conformational dynamics of ND2 antiporter-like subunit in intact and truncated complex I

04/10/2026 - Respiratory complex I is a large redox-driven proton pump and contributes to the proton motive force required for ATP generation in mitochondria and bacteria. It has been extensively studied with...

Your gut bacteria may reveal how fast your brain is aging

04/10/2026 - A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that...

Innovation for Climate Change Adaptation: A Meta‐Analysis

03/10/2026 - This study investigates the spatial patterns of specific phenomenon, for example, urban heat islands or biodiversity hotspots across regions, for example, Southeast Asia or the Mediterranean Basin,...

Adaptive respiratory bypass restores oxidative metabolism in NADH dehydrogenase-deficient Escherichia coli

01/10/2026 - Nicotinamide adenine dinucleotide is central to the cellular redox network and continuously cycles between its oxidized (NAD⁺) and reduced (NADH) forms. Membrane-bound NADH dehydrogenases are the...

Piezophilic activity dominates the Puerto Rico Trench deep subseafloor biosphere

01/10/2026 - Hydrostatic pressure is a defining feature of the deep ocean, yet how it structures microbial activity across the subseafloor biosphere is poorly understood. Here, we assess pressure effects on...
