Durability Of Dental Fillings Improves If The Enzyme Activity Of Teeth Is InhibitedA dental filling is more durable if the enzyme activity of the tooth can be inhibited. Professor Leo Tjaderhane of the Department of Pedodontics, Cariology and Endodontology at the University of Oulu, together with wide international collaborative team, has been developing this method with funding from the Academy of Finland.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Cannibalism Among Rattlesnakes Helps Females To Recover After BirthResearchers have produced the first quantitative description of cannibalism among female rattlesnakes (Crotalus polystictus) after monitoring 190 reptiles. The study has shown that these animals ingest on average 11% of their postpartum mass (in particular eggs and dead offspring) in order to recover energy for subsequent reproduction.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Nanoscale Materials Grow With The FlowScientists have shown that nanoscale, uniform lead islands on silicon are spontaneously and quickly created by unusually mobile atoms. The discovery of the "liquid-like" nanogrowth mechanism is promising for nanotechnology applications, which require fast, consistent, and efficient material growth for industrial-scale production.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Molecules Self-assemble To Provide New Therapeutic TreatmentsBy tailoring peptide amphiphiles, small synthetic molecules, and combining them with other molecules, researchers can make a wide variety of structures that may provide new treatments for medical issues including spinal cord injuries, diabetes and Parkinson's disease. Combining the PA molecules with hyaluronic acid, a biopolymer found in the human body in places like joints and cartilage, resulted in an instant membrane structure in the form of self-assembling sacs.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Tracking Warming Trend In Northwestern North AmericaA new study says that weather, especially in late winter and early spring, is getting warmer in northwestern North America.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Student Finds Rare Lincoln FingerprintA first-year university student has discovered what experts say is a fingerprint belonging to Abraham Lincoln from nearly 150 years ago.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 10:00 pm Hypertension Drug Dramatically Reduces Proteinuria In Kidney Disease PatientsTaking a much higher than recommended dose of the hypertension drug candesartan cilexetil effectively lowered the amount of protein excreted in the urine of patients with kidney disease, according to a new study. By reducing such proteinuria, the drug could potentially prevent the development of serious complications such as end-stage kidney disease and therefore save many patients' lives.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 4:00 pm Stem Cell Research Uncovers Mechanism For Type 2 DiabetesTaking clues from their stem cell research, investigators have discovered that a signaling pathway involved in normal pancreatic development is also associated with type 2 diabetes.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 4:00 pm Single-celled Algae Took The Leap To Multicellularity 200 Million Years AgoAncestors of the alga Volvox made the transition from the solitary life of a single-celled organism to that of a multicellular colony much earlier than previously thought, according to new research. Studying how algae made the leap provides clues to how organisms such as plants and animals evolved from single-celled ancestors. Mediating conflict between the cooperating cells is the key.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 4:00 pm Neural Circuitry Of Near-misses May Explain The Allure Of GamblingWhy do people gamble if they know that the house always wins? Researchers argue that near-misses, where the gambler narrowly misses out on the jackpot, may provide part of the answer.Source: ScienceDaily: Latest Science News | 22 Feb 2009 | 4:00 pm Why New Mothers Need Extra Attention (LiveScience.com)LiveScience.com - Around the globe, giving birth and caring for a baby is mostly women's work. But that work is fraught with difficulty, and women are often navigating a sea of critical choices as they try to breast-feed and bring up a child, especially under conditions of scarcity. Recent research by anthropologist Barbara Piperata of Ohio State University has shown that one of the most pressing issues for new mothers is the caloric cost of breast-feeding. ...Source: Yahoo!
