A systematic review of published studies on the use of medical cannabis in children and adolescents finds a notable lack of studies and a minimal number of the randomized, controlled trials needed to confirm the effectiveness of a treatment.

For families in the U.S., the costs of high-quality child care are exorbitant, especially for those with children under age five. A new policy proposal, "Public Investments in Child Care," by Dartmouth Associate Professor of Economics Elizabeth Cascio, finds that current federal child care tax policies are not benefiting the families most burdened by child care costs.

Simon Fraser University health sciences professor Bruce Lanphear is a Commissioner and author of The Lancet Commission on Pollution and Health that has released a report detailing the adverse effects of pollution on global health.

"This is the first global analysis of the impacts of pollution--air, water, soil, occupational--together as well as exploring the economic costs and the social injustice of pollution," says Lanphear. "Pollution, which is at the root of many diseases and disorders that plague humankind, is entirely preventable."

IN the long-established Jewellery Quarter of Birmingham, highly-skilled micro-businesses create and craft bespoke items using fine gems and precious metals. Often, they will take the source of their materials on trust, which can offer opportunities to rogue traders and make it difficult to develop policies towards corporate responsibility and environmental sustainability.

In a breakthrough experiment using a novel negative ion momentum imaging technique, researchers from Tata Institute of Fundamental Research, Mumbai India and Open University, Milton Kyenes, UK have shown -- for the first time -- that incoherent electrons displaying their quantum mechanical nature, can induce coherence in molecular systems on attachment. Their latest results published in the Journal, Nature Physics (DOI: 10.1038/nphys4289), show that the coherence induced by the capture of single electron by H2 molecule results in the ejection of H?

(PHOENIX, Ariz. Oct. 19, 2017) Research by a Barrow Neurological Institute neurosurgery team on novel imaging technique assessment of patients with lumbar spine degeneration was published in the Aug. 28 issue of PLOS ONE.

Mycoplasmas are very simple bacteria. They have a minimalist genome and no protective cell wall. Nevertheless, they are common and successful pathogens that cause infections in the lungs, joints and udders of animals like cattle or sheep. The bacteria can also cause chronic illnesses in humans. Due to a lack of or insufficient vaccines, these bacteria present a health risk as well as a risk of economic loss for the meat and dairy industry.

In Africa, tsetse flies transfer the sleeping sickness also to cattle. This leads to huge losses in milk, meat and manpower. The damage in Africa is estimated to be about 4.6 billion US dollars each year. Prof. Dr. Christian Borgemeister from the Center for Development Research (ZEF) at the University of Bonn and his colleagues from Kenya and the UK have developed an innovative way of preventing the disease. The scientists took advantage of the fact that tsetse flies avoid waterbucks, a widespread antelope species in Africa. The scientists imitated the smell of these antelopes.

New oral anticoagulants (NOACs) represent direct-acting drugs functioning selectively for one specific clotting factor. Their clinical indications are the prophylaxis and treatment of deep venous thrombosis and pulmonary embolism, the prevention of atherothrombotic episodes of individuals with acute coronary syndromes and atrial fibrillation (1).

Wildlife managers and ranchers in the greater Yellowstone ecosystem soon will have a new mapping tool for reducing the risk of brucellosis outbreaks in cattle. That's thanks to research led by scientists at the University of Wyoming and the U.S. Geological Survey.

The team of biologists built a computer model of elk behavior during spring migration to identify habitats with the highest risk of brucellosis spilling over from elk to cattle.
