New wheat disease dangers

Both plant and human diseases that can travel with the wind have the potential to spread far more rapidly than has been understood, according to a new study.

Potential myasthenia gravis treatment

Looking for a better treatment for the autoimmune disease myasthenia gravis, researchers have found that a protein in tick saliva shows promise in limiting the severity of the disease in an animal model.

Fighting persistent bacterial infections

Researchers have discovered a promising strategy for destroying the molecular scaffolding that can make Pseudomonas bacterial infections extremely difficult to treat.

Exploiting plant defences

Scientists are reporting development of a new class of "green" fungicides that could provide a safer, more environmentally-friendly...

How Salmonella survives in environment

Scientists at the University of Liverpool have demonstrated how a single-celled organism, living freely in the environment, could be a source of Salmonella transmission to animals and humans.

Shift in immune response regulation

An international team reports a paradigm shift in the regulation of immune response. Their results show that interaction with a linear ubiquitin chain is crucial for nuclear factor kappa B activation.

Simple fluorescent detector for TB

Scientists have developed an onsite method to quickly diagnose tuberculosis and expose the deadly drug-resistant strains of Mycobacterium tuberculosis that can mingle undetected with treatable strains.

Material resists biofilm growth

Scientists created a surface material on which they could manipulate and confine biofilm growth four times longer than current technologies.

When intestinal bacteria go surfing

During the course of an infection E. coli infest the intestinal mucosa, causing injury in the process, in contrast to benign bacteria.

Brothers in arms

Researchers have taken an in-depth look at the connection between flu infection and pneumonia, and their results have disproven a common theory about flu-like pneumonia.

Antibiotics that don't trigger resistance

Researchers are developing a new generation of antibiotic compounds that do not provoke bacterial resistance. The compounds work against two notorious microbes: Vibrio cholerae and E. coli 0157:H7.

No hiding place for infecting bacteria

Scientists describe how they used enzymes against products of the body's own defence cells to prevent Pseudomonas aeruginosa bacteria from building a protective biofilm

Cellular double jeopardy

Cells have two chances to fix the same mistake in their protein-making process instead of just one - a so-called proofreading step - that had previously been identified, according to new research.

Evolutionary origin of Rickettsia virulence genes

Scientists have revealed that genes for a specific type of molecular secretion system in Rickettsia, a structure that is linked in many...

New therapy protects lungs from inflammation

A novel anti-inflammatory therapy prevents acute lung injury in mice exposed to an inflammation-causing toxin, a recent study reports.

Protein helps immune cells

Researchers have identified a key protein that is required for immune cells called B lymphocytes to divide and replicate themselves.

Drug blocks deadly viruses

Two highly lethal viruses that have emerged in recent outbreaks are susceptible to chloroquine, an established drug used to prevent and treat malaria, according to a new basic science study.

New origin found for a critical immune response

An immune system response that is critical to the first stages of fighting off viruses and harmful bacteria comes from an entirely different direction than most scientists had thought.

Vitamin A signals offer autoimmunity clues

Researchers have discovered that dendritic cells can respond to the same compound, through two different receptors, by sending out both stimulatory and calming messages at once.

Turning bacteria against themselves

Scientists have developed a way to manipulate bacteria so they will grow mutant sugar molecules on their cell surfaces that could be used against them as the key component in potent vaccines.
