Business in Key Biodiversity Areas: Minimizing the risk to nature

Eurekalert - Apr 20 2018 - 00:04
A roadmap for businesses operating in some of the most biologically significant places on the planet has been issued this week by the Key Biodiversity Area Partnership involving 12 of the world's leading conservation organizations -- including IUCN, International Union for Conservation of Nature.

On the shape of the 'petal' for the dissipation curve

Eurekalert - Apr 20 2018 - 00:04
Topological insulators are new materials that have been studied by many research groups around the world for more than ten years. The main advantage of such materials is the presence (under certain symmetry conditions) of dissipationless states at the sample boundary, while the bulk material retains the properties of an insulator. In view of these properties, it is hoped that topological insulators can be used in advanced communications and information processing systems, as well as in quantum computing.

Genomics study in Africa: Demographic history and deleterious mutations

Eurekalert - Apr 20 2018 - 00:04
Scientists from the Institut Pasteur set out to understand how the demographic changes associated with the Neolithic transition also influenced the efficacy of natural selection. By comparing the genome diversity of more than 300 individuals from groups of forest hunter-gatherers (pygmies) and farmers (Bantu-speaking peoples), from western and eastern Central Africa, they discovered that the reason pygmies did not suffer from excessive deleterious mutations was because of their genetic diversity and their admixture with the Bantu peoples.

Trees are not as sound asleep as you may think

Eurekalert - Apr 20 2018 - 00:04
High-precision three-dimensional surveying of 21 different species of trees has revealed a yet unknown cycle of subtle canopy movement during the night. The 'sleep cycles' differed from one species to another. Detection of anomalies in overnight movement could become a future diagnostic tool to reveal stress or disease in crops.

How do people die in Switzerland today?

Eurekalert - Apr 20 2018 - 00:04
Today, almost two thirds of deaths in Switzerland aren't unexpected. How does the cultural context specific to each linguistic region influence end-of-life decisions? Researchers from the universities of Zurich and Geneva noticed significant differences between regions. However, these differences are not always more important than those observed between these regions and the countries with which they share the same language. These results are important to help ground debates on end of life decisions on facts.

A study links soil metals with cancer mortality

Eurekalert - Apr 20 2018 - 00:04
Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.

Treatment of cancer could become possible with adenovirus

Eurekalert - Apr 20 2018 - 00:04
An international team of researchers led by professor Niklas Arnberg at Umeå University, shows that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy. The study is published in the latest issue of the scientific journal "Proceedings of the National Academy of Sciences of USA", PNAS PNAS April 19, 2018. 201716900

New DNA screening reveals whose blood the vampire bat is drinking

Eurekalert - Apr 20 2018 - 00:04
The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens. Now, a new study describes a new DNA method to efficiently screen many vampire bat blood meal and fecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from.

Structured light and nanomaterials open new ways to tailor light at the nanoscale

Eurekalert - Apr 20 2018 - 00:04
Joint research between Tampere University of Technology, (Finland) and University of Tübingen (Germany) has shown that carefully structured light and matching arrangements of metal nanostructures can be combined to alter the properties of the generated light at the nanometer scale. The teams have shown that the efficiency of nonlinear optical fields generated from the oligomers is strongly influenced by how the constituents of the oligomer constituents are illuminated by structured light.

Russian scientists learned to perform the diagnose by analyzing saliva

Eurekalert - Apr 20 2018 - 00:04
Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) within the framework of the Project 5-100 developed a unique method of immune diseases diagnosing before the symptoms appear. Scientists proposed a laser-correlation spectroscopic technique (also called dynamic light scattering) for studying the immune response in body fluids, for example, in saliva.

Compound improves stroke outcome by reducing lingering inflammation

Eurekalert - Apr 20 2018 - 00:04
An experimental compound appears to improve stroke outcome by reducing the destructive inflammation that can continue months after a stroke, scientists report.Rats consuming compound 21 following a clot-based stroke -- the most common type in humans -- don't have a smaller stroke size but do have better memory and movement in its aftermath, says Dr. Adviye Ergul, vascular physiologist and Regents' Professor in the Department of Physiology at the Medical College of Georgia at Augusta University.
