For Women, Marital Distress Means Less Relief From Stress
Here's a novel idea for unwinding after a stressful day at the office: find a happy marriage. That's the suggestion from a new study that tracked levels of cortisol, a key stress hormone, among 30 Los Angeles married couples involved in one of our age's trickiest juggling acts -- raising kids when both parents work full time. Magnetic Nanoparticles Assembled Into Long Chains
Chains of 1 million magnetic nanoparticles have been assembled and disassembled in a solution of suspended particles in a controlled way, scientists at the National Institute of Standards and Technology (NIST) report. Such particles and structures, once their properties are more fully understood and can be manipulated reliably, may be useful in applications such as medical imaging and information storage. Trends in Terrorism: 2006
This July 2006 CRS (Congressional Research Service) Report for Congress surveys trends in terrorism, including more "micro-actors"(small autonomous groups and individuals), increased sophistication, and an overlap of terrorism with international crime. Includes statistics and policy discussions. Opens directly into a PDF file. Provided by the U.S. Department of State, Foreign Press Centers. Sexes Differ In Their Immune Reactions To Burnout On The Job And Depre
Recent findings show that work-related burnout can lead to inflammatory processes, which plays a key role in the initiation and progression of cardiovascular disease and other inflammatory-linked illness. Now, researchers find evidence that men and women differ in their inflammatory reactions to work-related burnout and depression. Patients With Diabetes Need Better Advice About Home Glucose Monitorin
A new study calls for better advice about home blood glucose monitoring for patients with non-insulin dependent (type 2) diabetes. Some experts believe that daily self monitoring helps to control blood glucose levels and it is often recommended. But others believe that self monitoring is complex and inconvenient and can lead to feelings of frustration and guilt. As such, there is still no firm agreement about the role and value of self monitoring for patients with type 2 diabetes. How to act on high readings was a consistent problem. At The Root Of Nutrient Limitation, Ecosystems Are Not As Different As
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns -- eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are 'hot-dog limited'-- the extra buns are worthless without hot dogs to fill them. Such limiting factors are a cornerstone of natural ecology, where phosphorus or nitrogen limits plant production in most ecosystems. Leukemia Patients Survive With Stem Cell Transplant
A new study published in the New England Journal of Medicine confirms that stem cells derived from the umbilical cords of newborn babies are a viable and effective transplant source for thousands of leukemia patients who have no other treatment option. Kids Need More Time Than Adults Give Them, Study Finds
The fast pace that parents and educators employ to get their kids to learn is beyond a youngster's perceptual ability, a study finds. Protein Synthesis Can Be Controlled By Light, Opening Way For New Scie
Proteins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult. Now, a team of chemists and neurobiologists led by Timothy Dore at the University of Georgia and Erin M. Schuman at the California Institute of Technology has found a way to use light to regulate protein synthesis in specific locations. Researchers Find BRCA1 Tumor Suppression Nullified By Cyclin D1
Scientists have discovered that a protein called cyclin D1, grossly overproduced in about half of all cases of breast cancer, can also disrupt BRCA1's normal role as a cancer inhibitor. Because cyclin D1 binds to the same estrogen receptor as does BRCA1, when the cell is flooded with cyclin D1, BRCA1 is unable to activate a pathway that stops cancer development.Study results reaffirm cyclin D1 as a candidate target for molecular therapeutic control of breast tumor development.
