1. Taking antibiotics? Sugar may be making the damage worse

   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 sweets during and after antibiotic treatment could be a simple way to reduce this damage, though clinical trials are still needed.

2. A new way to fight gum disease without wiping out good bacteria

   Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.

3. Scientists may have found a “unifying theory” of chronic fatigue

   Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door to new blood tests and treatments.

4. Scientists find new virus behind mysterious tick illness

   Scientists have discovered a new tick-borne virus in China that causes flu-like illness and may account for previously unexplained cases of fever, fatigue, digestive problems, and low platelet counts. Most patients with ALTNV alone recovered, but coinfections with another dangerous tick-borne virus were linked to more serious complications.

5. 160-million-year-old proteins show surprising power against superbugs

   Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for designing treatments as antibiotic resistance becomes an increasingly serious threat.

6. Rare pregnancy infections may triple the risk of autism

   A major Swedish study of 3.7 million people has found that rare TORCH infections passed from a pregnant woman to the fetus are linked to much higher risks of autism and intellectual disability later in life. Children with a congenital TORCH infection were about three times more likely to be diagnosed with autism, more than seven times more likely to have an intellectual disability, and up to 30 times more likely to have severe to profound intellectual disability.

7. Brain scans reveal a possible cause of long COVID fatigue and brain fog

   Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.

8. A deadly ebola relative is surging after years in the shadows

   A growing Bundibugyo virus outbreak is showing how a little-known relative of Ebola can become a major threat when diagnosis and treatment options are limited. Experts warn that preparing only for familiar pathogens could leave the world vulnerable when rare but deadly viruses suddenly reemerge.
