Rockefeller scientists reveal how a narrow-spectrum antibiotic selectively targets C. diff

Most antibiotics are double-edged swords. Besides killing the pathogen they are prescribed for, they also decimate beneficial bacteria and change the composition of the gut microbiome.

Certain RNA molecules may serve as markers of cellular stress in different diseases

The body's ability to respond to various types of stress is essential for maintaining health, and failure of such adaptive stress responses can trigger or worsen numerous diseases.

Powerhouse-pruning protein may be a sound target to help trigger new blood vessel growth

A protein that helps keep our cell powerhouses working at a premium appears to also help make energy rapidly available when it's time to make new blood vessels.

Researchers discover new type of cell that may play a key role in human lung diseases

A new type of cell that resides deep within human lungs and may play a key role in human lung diseases has been discovered by researchers at the Perelman School of Medicine at the University of Pennsylvania.

Globins in the body help fight liver disease

Anti-fibrotic therapy is still a medical necessity in the treatment of chronic liver disease in humans. The anti-fibrotic activity of globin family members in hepatic stellate cells (HSCs), the principal cell type involved in liver fibrosis, was reported by a research group led by Professor Norifumi Kawada of Osaka Metropolitan University (OMU).

Ancestors of many animal species may have inhabited a deltaic environment

The ancestors of many animal species alive today may have lived in a delta in what is now China, new research suggests.

Interactions of marine microbes and minerals may have led to oxygen build up in the atmosphere

For the first 2 billion years of Earth's history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated at levels that would impact the global biosphere.

Microbial fertilizer factory on the Earth's seafloor helped support complex life

Scientists reveal a new part of the recipe for complex life on planets, and it involves the onset of a microbial fertilizer factory on the Earth's seafloor roughly 2.6 billion years ago.

Unusual partners aid new blood vessel development

Insufficient oxygen to an area like the heart or legs, called hypoxia, is a cue to our bodies to make more blood vessels, and scientists have found some unusual partners are key to making that happen.

LMU researchers show how the brain distinguishes between various social influences

LMU researchers show what happens in the human brain when we try to influence other people or when we ourselves are influenced by others.

Researchers find increased red blood cell destruction in astronauts

A change in the volume of red blood cells has been documented in astronauts since the earliest space missions.

Lifelong exercise may help counteract the deterioration of fat tissue function with age

Fat tissue plays an important role in human health. However, our fat tissue loses function as we age, which can lead to type 2 diabetes, obesity, cancer and other ailments.

Researchers engineer strains of nitrogen-fixing soil bacterium to produce ammonia

Researchers from Washington State University have engineered strains of the ubiquitous, nitrogen-fixing soil bacterium Azotobacter vinelandii to produce ammonia and excrete it at high concentrations, transferring it into crop plants in lieu of conventional chemical fertilizers.
