Mobile phone radiation may affect memory performance in adolescents

Eurekalert - Jul 19 2018 - 00:07
Radiofrequency electromagnetic fields may have adverse effects on the development of memory performance of specific brain regions exposed during mobile phone use. These are the findings of a study involving nearly 700 adolescents in Switzerland. The investigation, led by the Swiss Tropical and Public Health Institute (Swiss TPH), will be published on Thursday, July 19, 2018 in the peer-reviewed journal Environmental Health Perspectives.

Determining the bioaccumulation of 9 metals in aquatic invertebrates in mining areas

Eurekalert - Jul 19 2018 - 00:07
A study conducted by the UPV/EHU's Animal Ecotoxicity and Biodiversity Group in collaboration with the University of Vigo has proposed an ecological threshold concentration of 9 metals for 10 taxa of aquatic macroinvertebrates from clean sites in the Nalón river basin (Asturias). This is the first step towards incorporating into river management plans quality criteria relating to the bioaccumulation of hazardous substances, as required by the EU.

App, brief intervention may be lifesaver for suicidal teens

Eurekalert - Jul 19 2018 - 00:07
A preliminary study from UT Southwestern's O'Donnell Brain Institute shows an intervention program that includes a personalized app could make a difference: Researchers found the rate of attempted suicides by teenagers who received the intervention was halved compared to those who received the standard care during their hospitalization.

A smart safe rechargeable zinc ion battery based on sol-gel transition electrolytes

Eurekalert - Jul 19 2018 - 00:07
Thermal runaway has been a long-standing issue impeding the development of high-energy-density batteries. Recently, a research team led by Prof. Chunyi Zhi from City University of Hong Kong has successfully synthesized a temperature-sensitive sol-gel transition electrolyte and incorporated it into a rechargeable Zn/α-MnO2 battery system. The battery operation would be inhibited at high temperature due to gelation of the sol-gel electrolyte and then restore working condition after cooling down, exhibiting a temperature-dependent dynamic electrochemical performance.

Mayo Clinic study: Anesthesia, surgery linked to decline in memory and thinking

Eurekalert - Jul 19 2018 - 00:07
In adults over 70, exposure to general anesthesia and surgery is associated with a subtle decline in memory and thinking skills, according to new Mayo Clinic research. The study analyzed nearly 2,000 participants in the Mayo Clinic Study of Aging and found that exposure to anesthesia after age 70 was linked to long-term changes in brain function. The results appear in the British Journal of Anaesthesia.

Having the right name helps one to find housing

Eurekalert - Jul 19 2018 - 00:07
Discrimination against ethnic minorities on the housing market is declining -- in Germany and other Western European countries and in the USA. But a new meta-study shows that applicants' surnames still influence the selection of new tenants.

Evidence of Salmonella Paratyphi C found for the first time in medieval northern Europe

Eurekalert - Jul 19 2018 - 00:07
Genome research conducted by the University of Warwick suggests that enteric fever, a potentially lethal disease more commonly found in hot countries, was present in medieval Europe. Salmonella Paratyphi C causes enteric fever, a life-threatening infection, and has been detected in a 800 year old human skeleton discovered in Trondheim, Norway.

Analytical tool predicts genes that can cause disease by producing altered proteins

Eurekalert - Jul 19 2018 - 00:07
A new computational tool predicts genes that can cause disease due to the production of truncated or altered proteins that take on a new or different function, rather than those that lose their function.

Scientists surmount epigenetic barriers to cloning with two-pronged approach

Eurekalert - Jul 19 2018 - 00:07
An international group of researchers have raised the viability of mice that were cloned using a method called somatic cell nuclear transfer, by stimulating two epigenetic factors, and by doing this have shown that creating cloned animals more efficiently will require further work in the area of epigenetics. They have also uncovered a key epigenetic mechanism that appears to be a major impediment to the development of the fetus after implantation.

Analysis of prostate tumors reveals clues to cancer's aggressiveness

Eurekalert - Jul 19 2018 - 00:07
Using genetic sequencing, scientists have revealed the complete DNA makeup of more than 100 aggressive prostate tumors, pinpointing important genetic errors these deadly tumors have in common. The study lays the foundation for finding new ways to treat prostate cancer, particularly for the most aggressive forms of the disease.

Complementary medicine for cancer can decrease survival

Eurekalert - Jul 19 2018 - 00:07
People who received complementary therapy for curable cancers were more likely to refuse at least one component of their conventional cancer treatment, and were more likely to die as a result, according to researchers from Yale Cancer Center and the Cancer Outcomes, Public Policy and Effectiveness Research Center (COPPER) at Yale School of Medicine. The findings were reported today online in JAMA Oncology.

Association of monthly high-dose vitamin D supplementation and cancer risk

Eurekalert - Jul 19 2018 - 00:07
Monthly high-dose vitamin D supplementation without calcium for up to four years wasn't associated with reduced cancer risk among adults in New Zealand. This study analyzed data from a randomized clinical trial that included a placebo group. There were 328 total cases of  cancer, with 165 among 2,558 participants (6.5 percent) who received monthly high-dose vitamin D supplementation and 163 among 2,550 participants (6.4 percent) in the placebo group.

Are vision impairments more frequent among children with developmental dyslexia?

Eurekalert - Jul 19 2018 - 00:07
Developmental dyslexia emerges in childhood and is a reading disorder believed to involve language processing deficits. Reading is also a visual task but the potential role of visual processing in developmental dyslexia has been controversial. This study was a small observational study to assess the frequency of visual deficits in 29 children with developmental dyslexia compared with 33 typically developing reading children.
