| Graphene reveals its magnetic personality Posted: 08 Jan 2012 11:36 AM PST Can organic matter behave like a fridge magnet? Scientists have now shown that it can. Researchers took nonmagnetic graphene and then either 'peppered' it with other nonmagnetic atoms like fluorine or removed some carbon atoms from the chicken wire. The empty spaces, called vacancies, and added atoms all turned out to be magnetic, exactly like atoms of, for example, iron. |
| A decade of research shows PET effectively detects dementia Posted: 07 Jan 2012 12:18 PM PST Scientists find that a method of positron emission tomography safely and accurately detects dementia, including the most common and devastating form among the elderly, Alzheimer's disease. |
| Mass prostate cancer screening doesn't reduce deaths, study suggests Posted: 07 Jan 2012 12:18 PM PST There's new evidence that annual prostate cancer screening does not reduce deaths from the disease, even among men in their 50s and 60s and those with underlying health conditions, according to new research. |
| Listening to music can be effective for reducing pain in high-anxiety persons Posted: 05 Jan 2012 01:17 PM PST Distraction is an effective pain reliever, and a new study concludes that listening to music can be effective for reducing pain in high-anxiety persons who can easily become absorbed in cognitive activities. |
| World Trade Center responders: PTSD and respiratory illness linked Posted: 05 Jan 2012 12:46 PM PST More than 10 years after 9/11, when thousands of rescue and recovery workers descended on the area surrounding the World Trade Center in the wake of the terrorist attacks, a research team has published results of a study examining the relationship between the two signature health problems among WTC first responders—respiratory illness and post-traumatic stress disorder (PTSD). |
| Student team's glucose sensor uses DNA instead of chemicals Posted: 05 Jan 2012 12:00 PM PST People with diabetes may one day have a less expensive resource for monitoring their blood glucose levels, if research by a group of students becomes reality. |
| Pneumonia outbreak in endangered markhor goats Posted: 05 Jan 2012 11:57 AM PST If they didn't have enough to worry about from dodging poachers, snow leopards, and landslides in Central Asia's rugged mountains, a population of endangered markhor -- a majestic wild goat species -- has contracted pneumonia. |
| Who's the boss? Research shows cells influence their own destiny Posted: 05 Jan 2012 11:57 AM PST In a major shake-up of scientists' understanding of what determines the fate of cells, researchers have shown that cells have some control over their own destiny. |
| Quitting smoking: Starting Chantix earlier may make it easier to quit Posted: 05 Jan 2012 11:24 AM PST Smokers planning to kick the habit may have more success if they begin using a cessation medication several weeks before they actually try to quit. |
| Fibroblasts contribute to melanoma tumor growth Posted: 05 Jan 2012 10:16 AM PST Fibroblasts, cells that play a role in the structural framework of tissues, play an apparent role in melanoma tumor growth. Fibroblasts also contribute to melanoma drug resistance and may also facilitate the "flare" response when a tumor's metabolism is enhanced following a patient being removed from a targeted therapy, said researchers. |
| Mosquito immune system engineered to block malaria Posted: 05 Jan 2012 08:19 AM PST Researchers have demonstrated for the first time that the Anopheles mosquito's innate immune system could be genetically engineered to block the transmission of the malaria-causing parasite to humans. In addition, they showed that the genetic modification had little impact on the mosquito's fitness under laboratory conditions. |
