Magnetic probe successfully tracks implanted cells in cancer patients

By using MRI to detect magnetic probes of tiny iron oxide particles, an international research team for the first time has successfully tracked immune-stimulating cells implanted into cancer patients for treatment purposes. more  

9/11 panel makes recommendations for DNA-based identification after mass disasters

Only days after the Sept. 11, 2001 attacks on the World Trade Center, the National Institutes of Justice (NIJ) convened a panel of experts from the National Institutes of Health (NIH) and other institutions, asking them to serve as an advisory panel to develop a process to identify victims using DNA collected at the site of the tragedy. Today, in an article published in the journal Science, the panel reports that DNA-based efforts led to the identification of more than one-quarter of those reported missing. The article also makes recommendations to improve DNA identification in event of future terrorist attacks or mass disasters. more

Some foods and beverages could hold clues for future diabetes treatment

Following a doctor's advice on how to keep diabetes in check is always the best course of action and researchers are constantly on the lookout for compounds that someday could help physicians better treat the disease. Of special interest to chemists are naturally occurring compounds found in certain healthy foods and beverages. Often these compounds become the model or the active ingredient for new drug therapies that maximize the food's beneficial effects. more  

Do increased levels of testosterone play a role in Sudden Infant Death Syndrome?

Sudden Infant Death syndrome (SIDS) is the leading cause of unexpected death in infants ages one week to one year old. Although the number of SIDS related deaths has decreased due to greater public awareness regarding infants' sleep positions, the cause of SIDS remains unknown. However, a study in the November issue of The Journal of Pediatrics shows that elevated testosterone levels may put infants at greater risk for SIDS. more

Morals often sacrificed for the good of the country  

A new study published in the latest issue of Public Administration Review looks at the moral dilemmas and implications that arise when statesmen abandon their principles for the good of the state. Author Stephanie Newbold explains that elected officials often enter public office with an ideology or perspective for how the government should be managed and what it is and is not responsible for. But governing a nation is quite different from the way individuals govern themselves or what they believe the government should be. With the Louisiana Purchase, Thomas Jefferson turned on his values, but made the best decision for the economic, political, and national security interests of the American people. more

Stem cell microenvironment reverses malignant melanoma 

Northwestern University researchers have demonstrated how the microenvironments of two human embryonic stem cell (hESC) lines (federally approved) induced metastatic melanoma cells to revert to a normal, skin cell-like type with the ability to form colonies similar to hESCs. The researchers also showed that these melanoma cells were less invasive following culture on the microenvironments of hESCs. more

Researchers uncover new genes that control longevity

Safety for people with food allergies will be boosted later this month when new European laws will force manufacturers to label their food more accurately, but the laws do not offer full protection, says an editorial in this week's BMJ. more


Cherries may help lower blood sugar -- Researchers have identified a group of naturally occurring chemicals abundant in cherries that could help lower blood sugar levels in people with diabetes.
