Bioenergy Potential Unearthed in Leaf-Cutter Ant Communities
June 14, 2013 — As spring warms up Wisconsin, humans aren't the only ones tending their gardens. Colonies of leaf-cutter ants cultivate thriving communities of fungi and bacteria using freshly cut plant ... > full story -
Secrets of Biological Soil Crusts Uncovered
June 14, 2013 — Biologists have performed a molecular level analysis of desert biological soil crusts -- living ground cover formed by microbial communities -- to reveal how long-dormant cyanobacteria become ... > full story -
New Findings Regarding DNA Damage Checkpoint Mechanism in Oxidative Stress
June 14, 2013 — Researchers have uncovered a previously unknown surveillance mechanism, known as a DNA damage checkpoint, used by cells to monitor oxidatively damaged DNA. DNA repair takes place approximately 10,000 ... > full story -
Geneticists Solve Mystery of EEC Syndrome's Variable Severity in Children
June 14, 2013 — By identifying a protein that acts as a genetic modifier, scientists have solved the mystery of why some infants are born with a grave syndrome consisting of cleft palate and major deformities of the ... > full story -
Using Math to Kill Cancer Cells
June 14, 2013 — Scientists have outlined how advanced mathematical modelling can be used in the fight against cancer. The technique predicts how different treatments and genetic modifications might allow ... > full story -
Discovery of How a Gene That Regulates Factors Involved in Bacteria Pathogenicity Acts
June 14, 2013 — A discovery has been made of the way in which the glgS gene (now renamed as the “surface composition regulator”, scoR) acts in bacteria and how the mechanisms involved in bacterial ... > full story -
Chronic Drinking and Exposure to Particulate Matter Dramatically Decreases Lung Function
June 13, 2013 — Alveolar macrophage (AM) function plays a critical role in protecting the lungs by removing particulates. Chronic drinking causes persistent oxidative stress in the lungs, leading to impaired AM ... > full story -
Medieval Leprosy Genomes Shed Light on Disease's History
June 13, 2013 — Scientists have reconstructed a dozen medieval and modern leprosy genomes -- suggesting a European origin for the North American leprosy strains found in armadillos and humans, and a common ancestor ... > full story -
Dangerous Strains of E. Coli May Linger Longer in Water Than Benign Counterparts, Study Finds
June 13, 2013 — A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study ... > full story -
Programming Blood Forming Stem Cells
June 13, 2013 — By transferring four genes into mouse fibroblast cells, researchers have produced cells that resemble hematopoietic stem cells, which produce millions of new blood cells in the human body every day. ... > full story
