Asthma Medicine Halves Risk of Parkinson's

 

 

* By studying the effect of 1000 medicines, researchers discovered that medicine against asthma and blood pressure is linked to the risk of getting Parkinson´s disease.

* While the use of asthma medicine halves the risk of getting Parkinson's, one type of medicine against high blood pressure doubles the risk.

* The researchers examined more than 100 million prescriptions ordered over the last 11 years in Norway.

* These discoveries could be the start of a radically new treatment of Parkinson's patients.

Parkinson´s disease is a chronic disease with unknown causes. The disease destroys the brain cells that control body movements. Shivering, stiff arms and legs and poor coordination are typical symptoms of Parkinson's. The symptoms may develop slowly, and it sometimes takes time to make a correct diagnosis. Researchers at the Department of Global Public Health and Primary Care (IGS) at the University of Bergen (UiB) have completed a large study that included data from the Norwegian Prescription Database, in cooperation with researchers at Harvard University.

A team of biologists has found an unexpected source for the brain's development, a finding that offers new insights into the building of the nervous system. The research, which appears in the journal Science, discovered that glia, a collection of non-neuronal cells that had long been regarded as passive support cells, in fact are vital to nerve-cell development in the brain. "The results lead us to revise the often neuro-centric view of brain development to now appreciate the contributions for non-neuronal cells such as glia," explains Vilaiwan Fernandes, a postdoctoral fellow in New York University's Department of Biology and the study's lead author. "Indeed, our study found that fundamental questions in brain development with regard to the timing, identity, and coordination of nerve cell birth can only be understood when the glial contribution is accounted for." The brain is made up of two broad cell types, nerve cells or neurons and glia, which are non-nerve cells that make up more than half the volume of the brain. Neurobiologists have tended to focus on the former because these are the cells that form networks that process information.

Climate warming reduces the number of plant species in the tundra, but plant-eating animals, such as reindeer and voles, can turn this negative effect into something positive. The results of a study coordinated from Umeå University in Sweden are now published in Nature Communications. “By eating tall and wide-leaved plants, reindeer can increase light availability and thus allow more plant species to co-exist and benefit from warmer conditions,” says Elina Kaarlejärvi, post-doctoral researcher at Umeå University, who led the study. Earlier studies suggest that tundra plant diversity will decrease in response to a warmer climate. However, it is important to know whether the response depends on the abundance of grazing animals, particularly reindeer, voles and lemmings, which are very common in tundra ecosystems. Researchers at Umeå University in Sweden, and Oulu University in Finland, tested this through experimental warming of vegetation on tundra meadows with and without reindeer and voles.

Protecting minors online, a vital but tough case

Children are susceptible to online crime and abuse. The key to protecting these inexperienced internet users is to build more robust, easy-to-manage security and privacy features into browsers. EU-funded researchers are on the case. The ENCASE project is leveraging the latest advances in online security and privacy to design and implement a browser-based architecture for protecting youngsters from predators frequenting social networks, as well as other internet menaces. Key to the new developments being explored by the Cyprus-led team is ease-of-use, so guardians, whether at home or school, can easily activate and manage browser settings. To do this, they plan to develop a user-centric architecture (design, test and organise websites guided by user needs) focusing on distinct services, which can be combined to form what the team calls “an effective protective net” against, for example, cyber-bullying and lurid or abusive acts.

In a bid to foster a more sustainable and competitive olive-oil sector, the EU-funded BeFOre project is developing a molecular database of the most resilient olive varieties that have the highest agronomical potential. Over 1 200 varieties of olive are currently cultivated globally. For those interested in the molecular and agronomical aspects of the olive, this which makes it difficult to find agreed data As agricultural production faces new demands, variants of olive with a high resilience to climate change or relevance for functional foods are of particular interest to the olive-growing sector.

How Neanderthals made the very first glue

The world’s oldest known glue was made by Neanderthals. But how did they make it 200,000 years ago? Leiden archaeologists have discovered three possible ways. Publication in Scientific Reports, 31 August. A Neanderthal spear is predominantly made up of two parts, a piece of flint for the point, and a stick for the shaft. But one aspect is often overlooked, and has recently been puzzling archaeologists: the glue that fixes the point to the shaft. For this, Neanderthals used tar from birch bark, a material that researchers often assumed was complex and difficult to make.

A new study led by the University of Southampton has shed light on the swimming style of a prehistoric sea creature by creating a robot to mimic its movements.
 A Southampton team including Luke Muscutt, a PhD student in Engineering and the Environment, worked with partners at the University of Bristol to analyse the propulsion method of plesiosaurs –marine reptiles that lived at the same time as dinosaurs and died out more than 65 million years ago.
Plesiosaurs are unique among vertebrates because they used two near-identical pairs of flippers to propel themselves through the water – whereas other animals, including existing species such as turtles and sea lions, have differently constructed front and back sets, using the front ones mainly for thrust and the back ones for steering. However, the propulsion dynamics of the plesiosaur have long been debated, with various theories proposed since the 1950s.

Making a biocell that is as effective as a platinum fuel cell: that’s the feat that researchers in the Laboratoire de Bioénergétique et Ingénierie des Protéines (CNRS/Aix-Marseille Université) have achieved, in collaboration with the Centre de Recherche Paul Pascal (CNRS/Université de Bordeaux) and the Institut Universitaire des Systèmes Thermiques Industriels (CNRS/Aix-Marseille Université). Three years after making their first prototype biocell, the researchers have just reached a new milestone and increased its performance and stability. This biocell could, in the long run, offer an alternative to fuel cells that require rare and costly metals, such as platinum. Their work was published in Energy & Environmental Science on August 17, 2017. A fuel cell converts chemical energy into electrical energy via hydrogen combustion. Though it is considered to be a clean technology – because it does not emit greenhouse gases – fuel cells do use costly rare metal catalysts1, such as platinum, to oxidize hydrogen and reduce oxygen. In recent years, the identification of biocatalysts, enzymes with remarkable properties, has revitalized research in this area: their oxygen, and especially hydrogen, transformation activity is comparable to that of platinum.  Hydrogenase activity was, until recently, inhibited by oxygen and therefore incompatible with use in cells.

The drugs enter rivers and lakes from treatment plants and sewage overflows, threatening aquatic life, scientists say

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say. In a new study, researchers detected high concentrations of these drugs and their metabolized remnants in the brain tissue of 10 fish species found in the Niagara River. This vital conduit connects two of the Great Lakes, Lake Erie and Lake Ontario, via Niagara Falls. The discovery of antidepressants in aquatic life in the river raises serious environmental concerns, says lead scientist Diana Aga, PhD, the Henry M. Woodburn Professor of chemistry in the University at Buffalo College of Arts and Sciences. "These active ingredients from antidepressants, which are coming out from wastewater treatment plants, are accumulating in fish brains," Aga says. "It is a threat to biodiversity, and we should be very concerned.

Researchers dated the skeletal remains, stalagmite found in Tulum cave

 

Analysis of a skeleton found in the Chan Hol cave near Tulum, Mexico suggests human settlement in the Americas occurred in the late Pleistocene era, according to a study published August 30, 2017 in the open-access journal PLOS ONE by Wolfgang Stinnesbeck from Universität Heidelberg, Germany, and colleagues. Scientists have long debated about when humans first settled in the Americas.
