Genetics preserves traces of ancient resistance to Inca rule

7 hours 23 min ago
The Chachapoyas region was conquered by the Inca Empire in the late 15th century. Inca oral histories, written down after the Spanish conquest, claim that the native population was forcibly resettled out of Chachapoyas and dispersed across the Inca Empire. However, a new study in Scientific Reports uses genetic evidence to reveal that despite Inca conquest, the population of Chachapoyas has remained genetically distinct, and not assimilated with that of the Inca heartland.

Hot vibrating gases under the electron spotlight

7 hours 23 min ago
A Japanese research team led by the University of Tokyo studied the vibration of four gases using electron microscopy and spectroscopy by collaborating with Hitachi High-Technologies Corp. Combined with simulations, they measured the increased vibration at 1,000°C compared with room temperature. O2 and CH4 showed significant excitation, although the vibration of hot O2 was overestimated by the simulations. N2 and CO showed no increase in vibration, because of rigid bonds. The method can be used to design efficient gaseous reactions.

Smoking leads to less increase in life expectancy for less educated women

7 hours 23 min ago
Life expectancy in Sweden has risen steadily during the last few decades for most groups. One exception is women whose highest educational level is compulsory school. This is mostly because of smoking, says a new dissertation in sociology.'Life expectancy has stayed level in the last 20-30 years for women with only a compulsory schooling in Sweden, but it's increased for other social groups. A big piece of this puzzle is smoking,' say Olof Östergren, sociology researcher at Stockholm University.

Dementia and cognitive impairment more prevalent in rural than urban seniors

7 hours 23 min ago
Researchers present the first nationally representative study to find that dementia and cognitive impairment have consistently been more prevalent among rural dwelling seniors than urban dwelling seniors. Their findings, published in the American Journal of Preventive Medicine, further suggest that while lagging behind their urban counterparts, the cognitive health of seniors living in rural areas has benefited from early twentieth century investments in secondary education that led to rapid increases in high school graduation rates in rural communities.

Omalizumab improves efficacy of oral immunotherapy for multiple food allergies

Dec 11 2017 - 00:12
Combining a 16-week initial course of the medication omalizumab with oral immunotherapy (OIT) greatly improves the efficacy of OIT for children with allergies to multiple foods, new clinical trial findings show. After 36 weeks, more than 80 percent of children who received omalizumab and OIT could safely consume two-gram portions of at least two foods to which they were allergic, compared with only a third of children who received placebo and OIT.

Transfusion dependence a barrier to quality end-of-life care for some with leukemia

Dec 11 2017 - 00:12
For patients with advanced leukemia, access to high-quality end-of-life care appears to be reduced in those dependent on blood transfusions, according to a new study being presented during the 59th American Society of Hematology (ASH) Annual Meeting and Exposition in Atlanta. The study associates this reduced access and consequent diminished use of hospice services with a reduced quality of end-of-life care for these patients.
