NewsStudy reveals “bet-hedging” strategy that helps gut bacteria survive and recover
Researchers have discovered that many gut bacteria use a flexible survival strategy to withstand disruptions such as antibiotics and diet changes. Microbes can switch between functional states, rather than relying solely on genetic mutations, to try to survive shifting conditions.

NewsNew molecules can offer breakthrough in fight against antibiotic resistance
Researchers have shown how TriPcides can target the bacterium Staphylococcus aureus, including antibiotic‑resistant strains such as MRSA. The compounds disrupt the bacteria’s ability to cause infection and can also kill dormant bacterial cells, which are often difficult to treat with existing antibiotics.
