It also might help retail marketing and border control. |
| Opportunity To Usurp Reproductive Power Of Royal Throne Keeps Worker Termites Home
October 12, 2009 at 2:00 pm
|
| Termite offspring may stay in their birth colony to help their queen and king parents rather than leave to try and start their own family because their chance of inheriting the 'reproductive throne' is higher than their chance of successfully dispersing, finding a mate, and surviving to produce fertile offspring on their own. |
| Inhibitors Of Important Tuberculosis Survival Mechanism Identified
October 12, 2009 at 2:00 pm
|
| Attempts to eradicate tuberculosis are stymied by the fact that the disease-causing bacteria have a sophisticated mechanism for surviving dormant in infected cells. Now, a team of scientists has identified compounds that inhibit that mechanism -- without damaging human cells -- which could lead to the design of new anti-TB drugs. |

|
| Homicide of strangers by people with schizophrenia is so rare that is impossible to predict who might offend or when it might happen, say researchers. More than half of offenders in the study had never been treated for schizophrenia -- earlier treatment for the first episode of psychosis and good quality care could prevent some homicides, the study concludes. |

| Continuing Racial Differences In HIV Prevalence In U.S.
October 12, 2009 at 8:00 am
|
| HIV prevalence among African Americans is ten times greater than the prevalence among whites. This racial disparity in HIV prevalence has persisted in the face of both governmental and private actions, involving many billions of dollars, to combat HIV. In a new study, researchers examine factors responsible for the stark racial disparities in HIV infection in the U.S. and the now concentrated epidemic among African Americans. |

The study shows that the tool has the potential to be an easy-to-use measure to bolster motivation and thus improve health behaviors and outcomes in the growing population of older adults. |
| Physicians Bust Myths About Insulin
October 12, 2009 at 2:00 am
|
| People diagnosed with type 2 diabetes often resist taking insulin because they fear gaining weight, developing low blood sugar and seeing their quality of life decline. A study suggests that those fears are largely unfounded and that patients and physicians should consider insulin as a front-line defense, as opposed to a treatment of last resort for non-insulin-dependent diabetes. |

| A High Fat Diet During Pregnancy Can Lead To Severe Liver Disease In Offspring
October 12, 2009 at 12:00 am
|
| Scientists have discovered a previously unknown link between a mother's diet in pregnancy and non-alcoholic fatty liver disease in her child. Researchers have found that a high fat diet during a woman's pregnancy makes her offspring more likely to develop a severe form of fatty liver disease when they reach adulthood. The findings are another piece in the jigsaw for scientists who believe diets containing too high levels of saturated fat may have an adverse effect on our health. | |
