Pathogens Use Previously Undescribed Mechanism To Sabotage Host Immune System
New research identifies a previously unknown enzymatic mechanism that subverts the early host immune response and promotes pathogenicity by manipulating a common signaling pathway in host cells. The research may have important implications for the food industry and for development of new antibiotics.

Heads Or Tails? Scientists Identify Gene That Regulates Polarity In Regenerating Flatworms
When cut, a planarian flatworm can use a population of stem cells called neoblasts to regenerate new heads, new tails or even entire new organisms from a tiny fragment of its body. Mechanisms have been sought to explain this process of regeneration polarity for over 100 years, but until now, little was known about how planaria can regenerate heads and tails at their proper sites.

Protein Protects Brain Against Compound In Lead Poisoning, Liver Disease
Scientists have discovered that a protein known as PEPT2 protects the brains of mice from a naturally occurring but potentially toxic compound present in lead poisoning and in a class of liver diseases that can cause serious neurological complications.

Pheromone for mouse aggression found
A whiff of a single type of protein from urine is enough to make a male mouse pick a fight, researchers have found. Pheromone scents that elicit aggressive behaviour have long been predicted, but have proven elusive until now.

Cells mend damaged mouse hearts
Researchers have managed to restore heart function by transplanting muscle stem cells into damaged mouse hearts. Their results suggest that the technique could one day be used to heal heart tissue in humans.

'Scrambled' polymers kill drug-resistant bacteria
"Scrambled-up" polymers can kill bacteria, and may offer hope in beating problems of antibiotic drug resistance, suggests a new study. Researchers at the University of Wisconsin, in Madison, US, had been working on making molecules that mimic the short proteins known as "host-defence peptides".

Why Skin Is Strong: Cells Stick Like Velcro
Scientists have gotten their best look ever at interactions inside human skin cells, finding a Velcro-like setup that links them and makes skin strong while also supple. The cell-interior images, made with a new a technique called cryo-electron tomography, show the proteins responsible for cell-cell contacts for the first time.
