Online information on vaccines and Autism not always reliable, study shows

Jun 14 2018 - 00:06
Google search results in several countries can provide unreliable information based on old, 'weak' scientific studies. Researchers analyzing the top 200 websites in a search for 'vaccines autism' found that 10 percent -24 percent had a negative stance on vaccines, which can potentially impact on public health. The approach of using search results to monitor information available could be a useful tool for identifying countries at greater risk of misinformation.

Yellow fever: A new method for testing vaccine safety

Jun 14 2018 - 00:06
Scientists from the Institut Pasteur, the CNRS and Sanofi Pasteur have recently developed a novel alternative method to animal testing that can be used to verify the safety of vaccines such as the yellow fever vaccine. This original approach is based on the development of an in cellulo device using a 3D culture model, the 'BBB-Minibrain'. A patent application has been filed by the Institut Pasteur and Inserm. The results of this research were published in the journal Biologicals in May 2018.

Girls with high level of vitamin D have stronger muscles

Jun 14 2018 - 00:06
Girls are stronger with higher levels of vitamin D, but the association was not found in boys. These are the results from a new large study from the Odense Child Cohort, recently published in the Journal of Clinical Endocrinology and Metabolism. According to the study's first author, medical student Rada Faris Al-Jwadi, girls with low vitamin D have a 70 percent increased risk of being among the lowest 10 percent in a test for muscle strength.

Water fluoridation confirmed to prevent dental decay in US children and adolescents

Jun 14 2018 - 00:06
The fluoridation of America's drinking water was a great public health achievement in the twentieth century but there are few studies from the last three decades investigating the impact of water fluoridation on US dental health. A recent study "Water fluoridation and dental caries in US children and adolescents," published in the Journal of Dental Research, evaluated associations between the availability of community water fluoridation and dental decay experience in US child and adolescent populations.

Human and artificial intelligence join forces to study complexity of the brain

Jun 14 2018 - 00:06
A team of scientists lead by prof. Stein Aerts (VIB-KU Leuven) is the first to map the gene expression of each individual brain cell during aging, though they started small: with the brain of a fruit fly. Their 'cell atlas' provides unprecedented insights into the workings of the brain as it ages.

Gene testing could identify men with prostate cancer who may benefit from immunotherapy

Jun 14 2018 - 00:06
Scientists have identified a pattern of genetic changes that could pick out men with advanced prostate cancer who are likely to benefit from immunotherapy.Developing a genetic test to pick out these men could speed up the path of immunotherapy into use for prostate cancer patients.The research found that men whose tumors had a distinct pattern of genetic changes could be much more likely to benefit from immunotherapy than otherwise.

Are portable music players associated with hearing loss in children?

Jun 14 2018 - 00:06
The effect of portable music players on the hearing of children is unclear. A new study found that about one in seven children (9-11 years of age) showed signs of noise-induced hearing impairment, prior to exposure to known noise hazards such as club and concert attendance. Portable music players, used by 40 percent of 2,075 children in the study from the Netherlands, were associated with high-frequency hearing loss. Repeated measurements are needed to confirm this association.

Microbe breaks 'universal' DNA rule by using two different translations

Jun 14 2018 - 00:06
DNA is often referred to as the blueprint for life, however scientists have for the first time discovered a microbe that uses two different translations of the DNA code at random. This unexpected finding breaks what was thought to be a universal rule, since the proteins from this microbe cannot be fully predicted from the DNA sequence.

Agricultural intensification not a 'blueprint' for sustainable development

Jun 14 2018 - 00:06
New research suggests that the combined social and ecological results of increased agricultural intensification in low and middle-income countries are not as positive as expected.The study, led by researchers from the University of East Anglia (UEA) and University of Copenhagen, is the first to bring together current knowledge on how agricultural intensification affects both the environment and human wellbeing in these countries.

New evidence sheds light on how Parkinson's disease may happen

Jun 14 2018 - 00:06
Researchers at Baylor College of Medicine and Texas Children's Hospital have identified unexpected new key players in the development of an early onset form of Parkinson's disease called Parkinsonism.

Key ocean fish can prevail with changes to farmed fish, livestock diets

Jun 14 2018 - 00:06
A new study shows that if current aquaculture and agriculture practices remain unchanged into the future, wild forage fish populations likely will be overextended by the year 2050, and possibly sooner. However, making sensible changes in aquaculture and agriculture production would avoid reaching that threshold.

Naming rights for five new snail-sucking snake species auctioned to save forests in Ecuador

Jun 14 2018 - 00:06
Five new species of eye-catching snakes with curious eating habits were found to inhabit forests in Ecuador. With four of them already deemed at risk of extinction, the international research team decided to auction their naming rights and use the money to purchase and save the previously unprotected plot of land where some of these species dwell. Their study is published in the open access journal ZooKeys.

Foods combining fats and carbohydrates more rewarding than foods with just fats or carbs

Jun 14 2018 - 00:06
Researchers show that the reward center of the brain values foods high in both fat and carbohydrates -- i.e., many processed foods -- more than foods containing only fat or only carbs. A study of 206 adults, to appear June 14 in the journal Cell Metabolism, supports the idea that these kinds of foods hijack our body's inborn signals governing food consumption.
