The Stenotrophomonas maltophilia MntR miniregulon includes novel extracytoplasmic components and affects replication in Acanthamoeba castellanii phagosomes Manganese homeostasis is crucial for bacterial survival, particularly for opportunistic pathogens like Stenotrophomonas maltophilia that switch lifestyles between contrasting environments. This study ...

I'm glad to share the latest preprint from our lab www.biorxiv.org/content/10.1.... This study elucidates the manganese homeostasis system in S. maltophilia, demonstrating that MntH is essential for optimal replication within Acanthamoeba castellanii phagosomes. Kudos to Stefany Argueta👏🙌!

The human phageome: niche-specific distribution of bacteriophages and their clinical implications | Applied and Environmental Microbiology In recent years, there has been a tremendous increase in interest in human microbiome studies. The great part of this study area is covered by bacteria; however, bacteriophages (phages, viruses able to infect bacteria) also play a crucial role in this structure. Phages, as a significant part of the microbiome, have become the subject of increasing interest. Nevertheless, studies of the phageome remain challenging due to the great diversity of these viruses and lack of universal markers (unlike bacteria which have 16S rRNA for identification) (1). Traditional methods of phage identification based on bacterial host cultures have limited applicability for phage detection, mostly due to the significant contribution of laboratory unculturable or difficult-to-culture bacteria that are hosts for many phages constituting the phageome. These barriers have been overcome to some extent by the use of high-throughput DNA sequencing like next-generation sequencing (NGS). Application of this technology was a milestone in phageome studies (2). NGS has become the major tool for exploring and investigating phage presence in biological samples. Sequencing-based molecular methods have revealed that many human niches are inhabited by unique and place-specific microbiomes including phages (3). Due to the development of metagenomic profiling, comprehensive analysis of phages inhabiting different compartments of human bodies has become possible. These analyses demonstrated that phages are most abundant in the oral cavity, gastrointestinal tract, urinary tract, skin, and lungs (4).

quote on a dark blue and purple background from Sudip S. Parikh, CEO of the American Association for the Advancement of Science (AAAS), criticizing proposed cuts to science funding in the FY26 U.S. federal budget. The quote reads: “If enacted, the FY26 budget request would end America’s global scientific leadership. The cuts to science would imperil our nation’s future health, security and prosperity. This budget proposal stands in stark contrast to the President’s call for a renewed commitment to American scientific leadership. Congress has demonstrated a bipartisan commitment to investment in research and must do so again to answer the President’s call.” The quote is attributed to Sudip S. Parikh, CEO of AAAS and Executive Publisher of the Science family of journals. The AAAS logo appears at the bottom right.

I don't think anyone outside of universities, pharma and biotech, independent research institutions have any idea of what is happening right now. If you haven't sounded the alarm among your friends, family and colleagues, now is the time to do it.

Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.

A horizontal bar chart comparing various AI models' performance on R coding tasks. The chart shows percentages of correct (blue), partially correct (beige), and incorrect (orange) answers. Gemini 2.5 Flash demonstrates performance somewhere between 2.5 Pro and o4-mini, with thinking resulting in a 10% increase in the proportion of correct answers. Claude 3.7 Sonnet and o4-mini remain the top performers.
