New Enzyme and Bacteria Unlock Efficient Production of Healthy Sweetener

From saccharin in the 19th century to stevia and monk fruit in the 21st, researchers and the food industry have long sought a sweetener that delivers the taste of sugar without its drawbacks-excess calories, tooth decay, and heightened risk for obesity, insulin resistance, and diabetes.

Scientists Discover Tug-of-War Mechanism Driving Bacteria Flagella Direction Switching

Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.

Unusual Antibody Tactics Hinder Pathogen Attachment to Cells

Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.

Molecular Switch Found to Control Single-Celled to Multicellular Transitions

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures.

Tumor Bacteria Found to Drive Immunotherapy Resistance

Cleveland Clinic researchers have discovered that bacteria inside cancerous tumors may be key to understanding why immunotherapy works for some patients but not others.

Scientists Develop Noise Controller to Tame Random Cell Behavior

Why does cancer sometimes recur after chemotherapy? Why do some bacteria survive antibiotic treatment? In many cases, the answer appears to lie not in genetic differences, but in biological noise - random fluctuations in molecular activity that occur even among genetically identical cells.

Single-Donor Lung-on-Chip Enables Personalized TB Research

Researchers at the Francis Crick Institute and AlveoliX have developed the first human 'lung-on-chip' model using stem cells taken from only one person.

Antibiotic Resistance: A Global Crisis Threatening Modern Medicine's Future

Once a medical miracle, antibiotics are now losing their power. Across the world, common infections are becoming harder-and sometimes impossible-to treat. This new review paints a sobering picture of global antimicrobial resistance (AMR), tracing how bacteria and fungi are evolving faster than medicine can respond.

New Rat Study Reveals How Genetic Traits Ripple Through Social Microbiomes

The gut microbiome - made up of trillions of microbes in the digestive tract - is vital for digestion and overall health. Diet and medication shape these microbial ecosystems, but the contribution of genetics has been more difficult to ascertain.

Genes Can Spread Their Effects Through Shared Microbes

Your "roommate's" genes could be influencing the bacteria living in your gut, and vice versa, according to a study of rats published today in Nature Communications.

Environmental Fluctuations Can Help or Hinder Evolution

Every living being must cope with a changing world-summer gives way to winter, one year it floods and the next is a drought.

Essential Proteins May Have Evolved to Allow Misfolding Repair

Proteins need to fold into specific shapes to perform their functions in cells, but they occasionally misfold, which can prevent them from properly functioning and even lead to disease.

Specific Gut Bacteria Found to Control Weight and Blood Fat Levels

The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome-the bacteria and fungi in the gut-are associated with obesity and weight gain, raising the possibility that changing the microbiome could improve health.
