Scientists are reporting development of a new approach for dealing with offensive household and other odors — one that doesn't simply mask odors like today's room fresheners, but eliminates them at the source. Their research found that a deodorant made from nanoparticles — hundreds of times smaller than peach fuzz — eliminates odors up to twice as effectively as today's gold standard. A report on these next-generation odor-fighters appears in ACS' Langmuir, a bi-weekly journal.
COLUMBUS, Ohio -- Parents who share caregiving for their preschool children may experience more conflict than those in which the mother is the primary caregiver, according to a new study.
Results showed that couples had a stronger, more supportive co-parenting relationship when the father spent more time playing with their child. But when the father participated more in caregiving, like preparing meals for the child or giving baths, the couples were more likely to display less supportive and more undermining co-parenting behavior toward each other.
Everybody who has been aboard a ship has heard the advice: if you feel unsteady, look at the horizon. For a study published in Psychological Science, a journal of the Association for Psychological Science, researchers measured how much people sway on land and at sea and found there's truth in that advice; people aboard a ship are steadier if they fix their eyes on the horizon.
A recent study confirmed that low socioeconomic status (SES) is associated with higher risk of depressive symptoms in patients with rheumatoid arthritis (RA). Statistically significant differences in race, public versus tertiary-care hospital, disability and medications were found between depressed and non-depressed patients. Study findings are reported in the February issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
CHICAGO (January 26, 2011) – A first of its kind surgical quality improvement program for children has the potential to identify outcomes of children's surgical care that can be targeted for quality improvement efforts to prevent complications and save lives. The results of a study of the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (ACS NSQIP Peds) phase 1 pilot were published in the January issue of the Journal of the American College of Surgeons.
As many as ten to 20 per cent of nurses and nursing students may have substance abuse and addiction problems, but the key to tackling this difficult issue - and protecting public safety - is support and treatment, not punishment. That is the key message in a paper in the February issue of the Journal of Clinical Nursing.
Researchers have recommended six key points that could be built into alternative-to-dismissal (ATD) strategies after reviewing the latest research and professional guidance from countries such as the USA, Canada, New Zealand, Australia and the UK.
Gallium nitride (GaN) and zinc oxide (ZnO) are among the most technologically relevant semiconducting materials. Gallium nitride is ubiquitous today in optoelectronic elements such as blue lasers (hence the blue-ray disc) and light-emitting-diodes (LEDs); zinc oxide also finds many uses in optoelectronics and sensors.
The researchers approached the conversion with the goal that by 2030, all new energy generation would come from wind, water and solar, and by 2050, all pre-existing energy production would be converted as well.
AUSTIN, Texas—Young staghorn coral that fluoresce redder are less likely to settle and develop into coral polyps than their greener peers, University of Texas at Austin biologists have discovered.
Targets set for GPs to improve the care of patients with high blood pressure have had no impact, according to a new study published on bmj.com today.
Researchers found that nationally set targets in the UK, that have financial rewards for GPs if they are met, have made no discernible difference to improving care and outcomes for patients with hypertension (high blood pressure).
Around half of people aged over 50 have hypertension, which is one of the most treatable, but undertreated cardiovascular risk factors.
A collection of 12 reviews, comprising three reflective pieces and nine research and development agendas, is published as part of a sponsored Supplement on 25 January 2011 in PLoS Medicine. This Collection highlights the outcomes of a series of consultations among more than 250 experts that were undertaken by the Malaria Eradication Research Agenda (malERA) initiative.
Most women in rural Zambia deliver their babies at home without skilled care because of the long distances involved in reaching emergency obstetric care, so it is crucial to address the geographic and quality barriers to health care use. These are the key findings from a study by Sabine Gabrysch from Ruprecht-Karls-Universität, Heidelberg, Germany and colleagues at the London School of Hygiene & Tropical Medicine published in this week's PLoS Medicine.
WEST LAFAYETTE, Ind. - Researchers have invented a technique that uses inexpensive paper to make "microfluidic" devices for rapid medical diagnostics and chemical analysis.
The innovation represents a way to enhance commercially available diagnostic devices that use paper-strip assays like those that test for diabetes and pregnancy.
WASHINGTON, DC, January 25, 2011 – The tiger reserves of Asia could support more than 10,000 wild tigers – three times the current number – if they are managed as large-scale landscapes that allow for connectivity between core breeding sites, a new paper from some of the world's leading conservation scientists finds. The study, co-authored by World Wildlife Fund (WWF) scientists, is the first assessment of the political commitment made by all 13 tiger range countries at November's historic tiger summit to double the tiger population across Asia by 2022.
