Pediatric allergology: Fresh milk keeps infections at bay
Infants fed on fresh rather than UHT cow’s milk are less prone to infection, new research suggests. The authors recommend the use of alternative processing methods to preserve the protectants found in the natural product.

Structure of an iron-transport protein revealed
Iron is the most abundant trace element in humans. As a cofactor of certain proteins, it plays an essential role in oxygen transport and metabolism. Due to the major importance of iron in a wide variety of cellular processes, and the harm caused by its uncontrolled accumulation in the body, its uptake and storage is strictly regulated. In mammals, iron is imported into cells by the membrane transport protein DMT1. Mutations of DMT1, which affect its transport properties, lead to iron-related metabolic disorders such as anemia and the iron storage disease hemochromatosis.

Imaging electric charge propagating along microbial nanowires
Physicists report that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive human-made material.

Scientific breakthrough will help design antibiotics of the future
Computer simulations have been used to show how bacteria are able to destroy antibiotics -- a breakthrough which will help develop drugs which can effectively tackle infections in the future.

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth
Researchers have shown for the first time how bacteria can grow directly in the lungs of Cystic fibrosis patients, giving them the opportunity to get tremendous insights into bacteria behavior and growth in chronic infections.

High-speed evolution in the lab: Geneticists evaluate cost-effective genome analysis
Life implies change. And this holds true for genes as well. Organisms require a flexible genome in order to adapt to changes in the local environment. Researchers want to know why individuals differ from each other and how these differences are encoded in the DNA. In two review papers, they discuss why DNA sequencing of entire groups can be an efficient and cost-effective way to answer these questions.

How a molecular Superman protects genome from damage
A new role for the RNAi protein Dicer has been found in preserving genomic stability. Researchers discovered that Dicer helps prevent collisions during DNA replication by freeing transcription machinery from active genes. Without Dicer function, transcription and replication machinery collide, leading to DNA damage and massive changes across the genome -- changes that are associated with aging and cancer.

Cells' powerhouses were once energy parasites: Study upends current theories of how mitochondria began
Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.

Staph 'gangs' share nutrients during infection
Antibiotic-resistant bacteria can share resources to cause chronic infections, investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their 'friends.' The findings shed light on a long-standing question in infectious diseases and may inform new treatment strategies.

Cell architecture: Finding common ground
When it comes to cellular architecture, function follows form. Plant cells contain a dynamic cytoskeleton, which is responsible for directing cell growth, development, movement, and division. Over time, changes in the cytoskeleton form the shape and behavior of cells and, ultimately, the structure and function of the organism. New work hones in on how one particular organizational protein influences cytoskeletal and cellular structure in plants, findings that may also have implications for animal cytoskeletal organization, scientists report.
