A low-carb diet is considered a promising weight-loss solution. But does it really help to reach your dream weight? In a fact check for #UniNova, endocrinologist PD Dr. Eleonora Seelig explains that food quality matters more than cutting out carbohydrates.

A paper in Nature Microbiology presents Antimicrobial Single-Cell Testing, a large-scale live-cell imaging approach that quantifies bacterial killing in real time at single-cell resolution, which can predict treatment outcomes. go.nature.com/3Nwnez8 #microsky 🧪
This is figure 1, which shows that ASCT enables high-throughput assessments of bacterial viability.

7/ Take-home: antibiotic efficacy isn’t just about inhibiting growth, but also about killing bacteria in the right physiological state. Single-cell killing measurements predict in vivo outcomes, uncover new biology, and enable improved drug discovery, regimen design, and personalised diagnostics.

6/ Can ASCT help tailor treatments to individual patients? Strain-specific M. abscessus killing dynamics for amikacin, cefoxitin and imipenem were associated with individual patient outcomes, whereas most MICs were not.

5/ Can ASCT uncover new bacterial biology? By combining ASCT with whole-genome sequencing and GWAS, we identified a phage protein strongly linked to M. abscessus killing (of drugs targeting protein synthesis only). We experimentally validated this effect using gene knockout and complementation.

Lucas Boeck @lucboeck.bsky.social · 12/01/2026
4/ Is killing also shaped by the bacterium? Assessing >400 clinical isolates of Mycobacterium abscessus, we observed highly variable killing dynamics. These differences were distinct from drug resistance, yet largely driven by bacterial genetics.

Lucas Boeck @lucboeck.bsky.social · 12/01/2026
3/ Can ASCT guide drug development? Testing 65 drug regimens in Mycobacterium tuberculosis, we found that killing under starvation conditions (but not in nutrient-rich media) predicted infection outcomes in mice and humans. MICs did not.

Lucas Boeck @lucboeck.bsky.social · 12/01/2026
2/ To address this, we developed Antimicrobial Single-Cell Testing (ASCT): a high-throughput live-cell imaging approach that measures bacterial death in real time at single-cell resolution. Using ASCT, we tracked >140 million individual bacteria, for up to 7 days, across >20,000 conditions.

Lucas Boeck @lucboeck.bsky.social · 12/01/2026
1/ Most antibiotic tests measure bacterial growth inhibition, not bacterial death. This often fails to predict treatment outcomes, especially in mycobacterial infections, where therapy is long, requires multiple antibiotics and is frequently unsuccessful (e.g. M. abscessus).

NEW COMMENT! TB trials with purely microbiological primary endpoints give greater weight to outcomes that matter most, generalise better to non trial settings, are less biased if regimens differ in duration, and are often better powered #IDSky @catherineberry.bsky.social @sgschumacher.bsky.social

We found that many bacterial species use exogenous peptidoglycan fragments - released by lysis of neighboring cells - as a general danger signal, triggering a danger response that protects bacteria against many dangers: biofilm formation. Details here 👇 www.nature.com/articles/s41...

Peptidoglycan released by neighbouring kin or non-kin cell lysis induces physiological changes that protect from a range of stresses, including phage predation.
