Stem cells use 'first aid kits' to repair damage
Neural stem cells -- master cells that can develop into any type of nerve cell -- are able to generate mini “first aid kits” and transfer them to immune cells, according to a new study.

Nine fats to include in a healthy diet
Fats are often considered the enemy of good nutrition, but when included in a healthy diet they can boast several potential health benefits. Fatty acids and nutritional oils may benefit cognition, weight management, heart health, eye and brain development, and even mood.

Chemists modify antibiotic to vanquish resistant bacteria
Scientists have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria. The new vancomycin analog appears to have not one but two distinct mechanisms of anti-microbial action, against which bacteria probably cannot evolve resistance quickly.

Asian Americans lower insulin resistance on traditional diet
Asian Americans have been shown to lower insulin resistance on a traditional diet, researchers report. One part of this puzzle may lie in the transition from traditional high-fiber, low-fat Asian diets to current westernized diets, which may pose extra risks for those of Asian heritage, says the senior author of the study.

Abnormal properties of cancer protein revealed in fly eyes
Mutations in the human retinoblastoma protein gene are a leading cause of eye cancer. Now, scientists have turned to fruit fly eyes to unlock the secrets of this important cancer gene. Since fruit flies are essentially tiny people with wings, in terms of genetics, these model organisms can play a key role in advancing human medicine.

Parts of genome without a known function may play a key role in the birth of new proteins
RNA called non-coding plays an important role in the evolution of new proteins, some of which could have important cell functions yet to be discovered, a study shows. The study analysed experiments carried out on six different species and identified almost 2,500 IncRNAs that were not in known databases.

Recruiting bacteria as technology innovation partners: New self-healing materials and bioprocessing technologies
For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of 'bad' biofilms around, a team of scientists see biofilms as a robust new platform for designer nanomaterials that could clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more.

Sepsis: New, novel therapy proposed by researchers
Pentatraxin 3 (PTX3), a protein that helps the innate immune system target invaders such as bacteria and viruses, can reduce mortality of mice suffering from sepsis, researchers have discovered. This discovery may lead to a therapy for sepsis, a major cause of death in developed countries that is fatal in one in four cases.

Unraveling cell division: Process of mitosis more clear, thanks to new research
The process of mitosis has made more clear, thanks to recent research. A new study describes how Topo 2, an enzyme that disentangles DNA molecules and is essential for proper cell division.

Proteins: Good networkers make prime targets
Proteins form either small or large networks to perform their functions. How these protein networks are subverted by pathogens has been investigated on a plant model by a research team who found that distinct pathogens like fungi and bacteria use the same tactic: launching targeted attacks on highly networked proteins that have multiple functions.
