Illegal activities threaten natural World Heritage

Earth sciences / SCIENCEDAILY - 14 July 2017

Illegal fishing, logging and poaching, are impacting two-thirds of the 57 natural World Heritage sites monitored by the International Union for Conservation of Nature this year, putting some of the world's most precious and unique ecosystems and species at risk.

Size not important for fish in the largest mass extinction of all time

Earth sciences / SCIENCEDAILY - 14 July 2017

Understanding modern biodiversity and extinction threats is important. It is commonly assumed that being large contributes to vulnerability during extinction crises. However, researchers have found that size played no role in the extinction of fish during the largest mass extinction of all time.

Why there are so many species of tropical trees and other organisms

Earth sciences / SCIENCEDAILY - 14 July 2017

Why does biodiversity grade from exuberance at the equator through moderation at mid-latitudes toward monotony at higher ones? Data from an international network of long-term forest dynamics research sites is finally providing an answer.

Most abundant viruses in Earth's oceans identified

Biology / SCIENCEDAILY - 14 July 2017

Forty-four of the most abundant new viruses in all the Earth's oceans have been identified by scientists. The finding has been achieved thanks to the application of cutting-edge techniques that mix flow cytometry and genomics and molecular biology techniques.

Textbook knowledge in molecular interactions refuted

Physics / SCIENCEDAILY - 14 July 2017

Van der Waals interactions between molecules are among the most important forces in biology, physics, and chemistry, as they determine the properties and physical behavior of many materials. For a long time, it was considered that these interactions between molecules are always attractive. Now, researchers have found that in many rather common situations in nature the van der Waals force between two molecules becomes repulsive.

Cocoa and chocolate are not just treats -- they are good for your cognition

Medicine / SCIENCEDAILY - 14 July 2017

Researchers have examined the available literature for the effects of acute and chronic administration of cocoa flavanols on different cognitive domains. It turns out that cognitive performance was improved by a daily intake of cocoa flavanols.
