Bacterial protein impairs important cellular processes

Areas of skin that have been damaged by an injury are ideal niches for the concentration of Pseudomonas aeruginosa, a bacterium which impairs the healing process in tissue and creates favorable conditions for infections. ...

Architecture of a bacterial power plant decrypted

Both humans and many other creatures need oxygen for survival. In the conversion of nutrients into energy, oxygen is converted to water, for which the enzyme oxidase is responsible. It represents the last step of the so-called ...

Fertilization discovery reveals new role for the egg

An unexpected discovery about fertilization from the University of Virginia School of Medicine reveals new insights on how sperm and egg fuse and could have major implications for couples battling infertility—and may lead ...

Understanding transporter proteins at a single-molecule level

Like a boat helping passengers cross a river, transporters move substances across cell membranes. This process is fundamental to the healthy functioning of cells in life forms from bacteria to humans. The function of these ...

Unknown virus discovered in humans

An international team based in Austria has unearthed a previously unknown type of virus in samples of human bodily fluids. The researchers were looking for viruses that infect bacteria, known as bacteriophages, with an emphasis ...

Cells control their dance of death

La Trobe University researchers have revealed for the first time how white blood cells control the final moments of their death, helping their own removal from the human body.

Antibiotics: New substances break bacterial resistance

Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a promising new class of active ingredients against resistant bacteria. In initial tests in cell cultures and insects, the substances were ...

New research explains how HIV avoids getting ZAPped

Humans have evolved dynamic defense mechanisms against the viruses that seek to infect our bodies—proteins that specialize in identifying, capturing and destroying the genetic material that viruses try to sneak into our ...

Targeted gene modification in animal pathogenic chlamydia

Researchers at Umeå University (Sweden), in collaboration with researchers at the University of Maryland and Duke University (U.S.), now for the first time successfully performed targeted gene mutation in the zoonotic pathogen ...

Microscopic biological motors using magnetotactic bacteria

Since their discovery in the 1970s, scientists have developed a strong interested for magnetotactic bacteria, an intriguing microorganism that moves along the magnetic field lines due the magnetite particles they grow in ...

Oxygen deficiency rewires mitochondria

Mitochondria burn oxygen and provide energy for the body. Cells lacking oxygen or nutrients have to change their energy supply quickly in order to keep growing. Scientists from the Max Planck Institute for Biology of Ageing ...
