Infectious bacteria hibernate to evade antibiotics
Researchers have discovered a surprising tactic of pathogenic bacteria when being attacked by antibiotics: hibernation.

How leaves talk to roots
New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.

Deciphering the link between skin allergies and the gut microbiota
Over the last few years, scientists have discovered connections between gut microbiota imbalances and various diseases. Now, in a study using mice, researchers have revealed a surprising relationship between a viral detection system, the composition of the gut microbiota, and the development of skin allergies. Their findings suggest potential new therapies.

Common weed killer linked to bee deaths
Honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria. Scientists believe this is evidence that glyphosate might be contributing to the decline of honey bees and native bees around the world.

Evidence that addictive behaviors have strong links with ancient retroviral infection
New research shows that an ancient retrovirus -- HK2 -- is more frequently found in drug addicts and thus is significantly associated with addiction.

Parasite makes quick exit when researchers remove the handbrake
Researchers have discovered a way to halt the invasion of the toxoplasmosis-causing parasite into cells, depriving the parasite of a key factor necessary for its growth. The findings are a key step in getting closer to a vaccine to protect pregnant women from the parasite Toxoplasma gondii, which carries a serious risk of miscarriage or birth defects.

DNA islands effective as 'anti-bacterial drones'
Genomic 'islands' that evolved from viruses can be converted into 'drones' that disable Staphylococcus aureus, bacteria that are often resistant to antibiotics, a new study finds.

Eradicating Helicobacter pylori infections may be a key treatment for Parkinson's disease
While human genetic mutations are involved in a small number of Parkinson's disease (PD) cases, the vast majority of cases are of unknown environmental causes, prompting enormous interest in identifying environmental risk factors involved.

Researchers explore how changes in diet alter microbiome in artificial intestine
Using an artificial intestine they created, researchers have shown that the microbiome can quickly adapt from the bacterial equivalent of a typical western diet to one composed exclusively of dietary fats.

The first predators and their self-repairing teeth
The earliest predators appeared on Earth 480 million years ago -- and they even had teeth which were capable of repairing themselves. A team of palaeontologists have been able to discover more about how these organisms were able to grow and regenerate their teeth.
