Bacteria Move Without Flagella: Sugar-Fueled Currents and Molecular Gearboxes
Unveiling a New Kind of Bacterial Motion Bacteria are renowned for their tiny flagella — whip-like propellers that broadcast their desire to roam. Yet a growing body of research from Arizona State University is changing that narrative. Scientists are documenting how bacteria can move without traditional flagella, employing less obvious tools such as sugar-fueled currents…

Flagella-Free Bacteria Movement: Sugar Currents and Gearboxes
What’s new in bacterial movement For decades, scientists have described bacterial motion as a simple story of tiny propellers—the flagella—that propel single cells through liquids. But fresh research from Arizona State University is reshaping that narrative. The studies uncover how some bacteria can move without their flagella, harnessing sugar-fueled currents and intricate molecular gear systems…

Bacteria Without Flagella: Sugar Currents Move Cells
New Ways Bacteria Move: Beyond the Flagellum For decades, scientists have linked bacterial movement to the flagellum, the whip-like propeller that propels many microbes through liquid environments. Yet a wave of new research from Arizona State University shows that bacteria can glide, crowd, and disperse using mechanisms that do not rely on flagella. By harnessing…

Sped-up Evolution in Gut Microbiome Could Help Bacteria Take Hold, UCLA Study Finds
New Insights into How Gut Bacteria Take Hold The human gut hosts a vast microbiome that outnumbers our own cells and plays a pivotal role in digestion, immune function, and even brain health. While much remains to be learned about these microscopic communities, a UCLA-led team has uncovered a mechanism that could explain how certain…

Targeting PAR2: Innovative Pathways to Relieve Gut Pain
New Insights into a gut pain signaling axis Abdominal pain is a common thread across many digestive disorders, from inflammatory bowel disease (IBD) to irritable bowel syndrome (IBS). Recent research has zeroed in on PAR2, a receptor located on the gut lining and pain-sensing nerves, as a pivotal driver of gut pain. PAR2 becomes activated…

Bacteria Survive Space Launch and Re-entry: Implications for Mars Missions
Groundbreaking Real-World Test Shows Bacteria Endure Spaceflight Stresses A new Australian-led study has demonstrated that the spores of Bacillus subtilis, a bacterium closely linked to human health, can endure the extreme conditions of a rocket launch and re-entry. The research tested rapid acceleration, short bursts of microgravity, and rapid deceleration, revealing that these hardy spores…

Why Are We All So Obsessed With Drinking Water and Reusable Bottles?
The rise of the water bottle craze From Stanley quencher mugs to bottles that look like tiny kegs, the wellness marketplace has transformed hydration into a lifestyle. It’s easy to poke fun at the obsession, but the trend taps into something deeper: a cultural shift toward proactive self-care. For many families, a back-to-school wish list…
