Single-Celled Fungi Multiply, Alien-Like, by Fusing Cells in Host

Health & Behavior

Microsporidia cause diarrhea, an illness called microsporidiosis and even death in immune-compromised individuals.In spite of those widespread medical problems, scientists were uncertain about how these single-celled fungi reproduced in human or animal cells. But in a study that employed transparent roundworms, biologists at the University of California San Diego succeeded in directly observing how these microorganisms replicate and spread. And what they saw surprised them.

Proton Pump Found to Regulate Blood pH in Stingrays

Science & Environment

Researchers at Scripps Institution of Oceanography at the University of California San Diego have discovered the same enzyme used by “boneworms” to dissolve whale carcasses, and that helps promote photosynthesis in corals, also regulates blood pH in stingrays.

MRI Technology Quantifies Liver Response in Nonalcoholic Steatohepatitis Patients

Health & Behavior

Researchers at the University of California San Diego School of Medicine have found that a form of magnetic resonance imaging (MRI) that non-invasively measures fat density in the liver corresponds with histological (microscopic tissue analyses) responses in patients with nonalcoholic steatohepatitis (NASH).

Flesh-Eating Infections in Rheumatoid Arthritis Patients Spur New Discovery

Health & Behavior

Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta (IL-1beta), a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Streptococcal infections than patients not on the drug, according to University of California San Diego School of Medicine researchers. Their study, published August 19 in Science Immunology, also uncovers a critical new role for IL-1beta as the body’s independent early warning system for bacterial infections.

Zika Infection May Affect Adult Brain Cells

Health & Behavior

Concerns over the Zika virus have focused on pregnant women due to mounting evidence that it causes brain abnormalities in developing fetuses. However, new research in mice suggests that certain adult brain cells may be vulnerable to infection as well. Among these are populations of cells that serve to replace lost or damaged neurons throughout adulthood, and are also thought to be critical to learning and memory.
