Scientists rank thousands of substances according to potential exposure level

An overwhelming number of chemicals from household and industrial products are in the environment – and hundreds are in our bodies. But for most of them, scientists have yet to determine whether they cause health problems. Now they've taken the first step toward doing that by estimating which substances people are exposed to the most. Their new method is published in the ACS journal Environmental Science & Technology.

BGI Tech and Hebei Agricultural University complete the genome sequencing of the jujube tree

October 27, 2014 — Cambridge, MA and Hebei, China — BGI Tech and Hebei Agricultural University jointly announced the complete, high quality sequencing of the Jujube genome. Jujube is the most economically important member of the Rhamnaceae family, and the Jujube genome is particularly difficult to sequence due the high level of heterozygosity and other complicating factors. It is the first time that a genome in the Rhamnaceae (Buckthorn) family has been sequenced.

Gentle caffeine boost for premature babies

The development of minimally and even non-invasive technologies is increasing in the medical field. It is now possible, for instance, to carry out a range of operative procedures using keyhole surgery with minimal use of the scalpel, leaving only tiny scars as a result. Similar opportunities are now becoming available when providing doses of active agents to patients – instead of using injections or probes to deliver drugs, it will in future be possible to supply them via a plaster which continuously, gently and painlessly delivers the required dosage through the skin.

Evolution of competitiveness

Virtually all organisms in the living world compete with members of their own species. However, individuals differ strongly in how much they invest into their competitive ability. Some individuals are highly competitive and eager to get access to high-quality resources, while others seem to avoid competition, instead making prudent use of the lower-quality resources that are left over for them. Moreover, the degree of competitiveness in animal and human societies seems to fluctuate considerably over time.

Prenatal phthalate exposures and anogenital distance in Swedish boys

The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally.

Background

Largest ever dataset of individual deaths in Africa & SE Asia reveals changing health

More than 110,000 individual deaths and their causes across 13 countries, including Ghana, South Africa, Kenya, Bangladesh and Vietnam, are contained in the new INDEPTH dataset. The data, collected by hundreds of researchers over two decades, are the first meaningful community-based information about cause of death in countries where individual deaths are not recorded automatically by national governments.

Integrins losing their grip lead to activation of T cell immune response

Integrins are adhesion molecules expressed on the surface of cells. They play a crucial role in "integrating" the cell exterior and the interior cytoskeleton in cells. The beta2-integrin family members are highly expressed in dendritic cells that are very important in immune responses. Dendritic cells pick up antigens in inflamed tissues and move to lymph nodes where they present the antigen to T cells and activate them to help fight infection.

Genome sequenced of enterovirus D68 circulating in St. Louis

Researchers at Washington University School of Medicine in St. Louis have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children's Hospital. Nationwide, the virus has spread rapidly in recent months and caused severe respiratory illness in young children, with some patients requiring hospitalization.

New scientific review reveals emerging and established health benefits of whole grain oats

CHICAGO, IL, OCTOBER, 29, 2014 – According to a new, wide-reaching collection of scientific reviews published in the October 2014 supplement issue of the British Journal of Nutrition, oats may play an important role in improving satiety, diet quality and digestive, cardiovascular and general metabolic health. In the supplement issue, entitled "Oats, More Than Just a Whole Grain," scientists from around the world explore the oat from agriculture and sustainability to nutrition policy and opportunity and new insights in nutritional science that go beyond cardiovascular health.

Why some butterflies sound like ants

Washington D.C, October 29, 2014 -- Ant nests can offer a lot to organisms other than just ants. They are well-protected, environmentally-stable and resource-rich spaces -- in many ways everything a tiny creature could ask for in a home. So long as you can live with an army of ants of course.

Kidney cancer in Central Europe

New research by the international Cancer Genomics of the Kidney consortium (CAGEKID) reveals an important connection between kidney cancer and exposure to aristolochic acid, an ingredient in some herbal remedies. The findings, published in Nature Communications, have important implications for public health.

Study sheds light on genetic architecture of kidney cancer

A new study on a large cohort of kidney cancer patients in Europe sheds light on the genetic architecture of the disease -- and reveals an apparent link between exposure to aristolochic acid and incidence of kidney cancer, particularly in Romania.

Diets high in fruit, vegetables, whole grains and nuts among factors to lower first-time stroke risk

Eating Mediterranean or DASH-style diets, regularly engaging in physical activity and keeping your blood pressure under control can lower your risk of a first-time stroke, according to updated AHA/ASA guideline published in the American Heart Association's journal Stroke.

Prostate cancer medications linked with increased risk of heart-related deaths in men with cardiovascular problems

A new study has found that certain prostate cancer medications are linked with an increased risk of dying from heart-related causes in men with congestive heart failure or prior heart attacks. Published in BJU International, the findings will help doctors and patients weigh the benefits and risks of the drugs.

Poor access to general surgeons increases the risk of ruptured appendix for young children

SAN FRANCISCO: Delayed treatment for appendicitis can often lead to a ruptured appendix. That's exactly what is more likely to happen to many children in North Carolina if they have to delay getting treatment because of poor access to general surgeons, according to new study findings presented this week at the American College of Surgeons 2014 Clinical Congress.
