New approaches for controlling pesticide exposure in children

2013-03-13
(Press-News.org) New research on household pesticide contamination emphasizes the need for less reliance on pesticides and more emphasis on neatness, blocking cracks where insects can enter and other so-called "integrated pest management" (IPM) measures, scientists have concluded. Their study appears in the ACS' journal Environmental Science & Technology.

Chensheng Lu and colleagues cite previous studies showing that urban, low-income, multifamily, public housing dwellings are prone to severe pest infestation problems. Families in Boston public housing developments, for instance, rank pest infestation, pesticide use and pest allergies second only to crime as matters of concern. In an effort to encourage use of IPM, which reduces reliance on traditional pesticides, Lu's team studied exposure to 19 pesticides among children in 20 families in Boston's public housing.

They found pesticides in all of the homes, along with indications — such as sighting of live pests or pest debris — that traditional pesticides were not effective. "The results from the current study, as well as other recent studies, conducted in low-income public housing, child care centers and randomly selected homes in the U.S. should accentuate the need for alternative pest management programs," the report states. IPM focuses on eliminating the cause of pest infestations by minimizing access to food, water, hiding places, and sealing cracks and other openings in walls to prevent entry of pests.

Paving the way for greater use of ancient medical knowledge

2013-03-13
Scientists are reporting an advance toward overcoming a major barrier to tapping the potential of traditional Chinese medicine (TCM) and India's Ayurvedic medicine in developing new and more effective modern drugs. Their report appears in ACS' Journal of Chemical Information and Modeling. Andreas Bender and colleagues explain that TCM has made key contributions to modern medicine. In the world's largest international clinical trial, for instance, scientists concluded that Artesunate, a derivative of the Chinese herb qinghao, should replace quinine as a treatment for ...

Breakthrough in battle against leukemia

2013-03-13
Scientists at Griffith University's Institute for Glycomics and The Saban Research Institute of Children's Hospital Los Angeles have discovered a critical weakness in leukaemic cells, which may pave the way to new treatments. The research team has demonstrated that leukaemic cells can be eradicated by removing a carbohydrate modification displayed on the cell's surface. Director of Griffith University's Institute for Glycomics, Professor Mark von Itzstein is the Australian team leader. He said the discovery is an important advance against leukaemia, a cancer of malignant ...

Its all in the way we move
2013-03-13
When, how and why modern humans first stood up and walked on two legs is considered to be one of the greatest missing links in our evolutionary history. Scientists have gone to the far ends of the earth – and the wonderful creatures in it - to look for answers to why we walk the way we walk. In the latest such search, researchers from the University of the Witwatersrand in Johannesburg (South Africa) have taken a closer look at bipedal kangaroos and wallabies and how they move compared to their cousin-marsupials, such as the quadrupedal Tasmanian wolf. In an article ...

Paraffin encapsulated in beach sand material as a new way to store heat from the sun

2013-03-13
The search for sustainable new materials to store heat captured from the sun for release during the night has led scientists to a high-tech combination of paraffin wax and sand. Their report on the heat-storing capability of this microencapsulated sand appears in ACS Sustainable Chemistry & Engineering. Benxia Li and colleagues explain the need for better materials that can store and release heat. These so-called "phase-change" materials" (PCMs) are essential, for instance, for storing heat from the sun for use in providing energy at night or during cloudy periods. PCMs ...

Younger doctors more likely to train and work closer to home

2013-03-13
Younger doctors are more likely than older generations to train and work in the same region as their home before entering medical school. New research published in the Journal of the Royal Society of Medicine investigating the geographical mobility of UK-trained doctors, reveals that 36% attended a medical school in their home region. 34% of hospital consultants and GP partners settled in the same region as their home before entering medical school. The geographical distribution of doctors is an important factor in the equitable distribution of health services. Trevor ...

Extreme water

2013-03-13
Earth is the only known planet that holds water in massive quantities and in all three phase states. But the earthly, omnipresent compound water has very unusual properties that become particularly evident when subjected to high pressure and high temperatures. In the latest issue of the Proceedings of the National Academy of Sciences (PNAS), a German-Finnish-French team published what happens when water is subjected to pressure and temperature conditions such as those found in the deep Earth. At pressures above 22 MPa and temperatures above 374°C, beyond the critical ...

Surprising control over photoelectrons from a topological insulator

Surprising control over photoelectrons from a topological insulator
2013-03-13
Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface. Researchers find TIs exciting partly because the electrons that flow swiftly across their surfaces are "spin polarized": the electron's spin is locked to its momentum, perpendicular to the direction of travel. These interesting electronic states promise many uses – some exotic, like observing never-before-seen fundamental ...

Evidence supports blocking immune response to enhance viral therapy against solid tumors

2013-03-13
Following several years of study, investigators have found more evidence that viral therapy to treat solid tumors can be enhanced by blocking the body's natural immune response. Oncolytic viruses have shown promise as anticancer agents, with variations of the herpes simplex virus (HSV) among the most commonly used. However, many studies have shown that the effectiveness of viral therapy to eradicate tumors has not been as successful with patients as it has been in the lab. These results have led researchers to examine the body's immune system response to determine what ...

Bradley Hospital researchers find age-related changes in how autism affects the brain

2013-03-13
EAST PROVIDENCE, R.I. – Newly released findings from Bradley Hospital published in the Journal of the American Academy of Child & Adolescent Psychiatry have found that autism spectrum disorders (ASD) affect the brain activity of children and adults differently. In the study, titled "Developmental Meta-Analysis of the Functional Neural Correlates of Autism Spectrum Disorders," Daniel Dickstein, M.D., FAAP, director of the Pediatric Mood, Imaging and Neurodevelopment Program at Bradley Hospital, found that autism-related changes in brain activity continue into adulthood. ...
