VUB geologists create new toolkit to study the consequences of meteorite impact
What exactly happens during and immediately after the impact of a meteorite? That was the question posed by a team of geologists from the research group Archaeology, Environmental Changes & Geo-Chemistry (AMGC) at Vrije Universiteit Brussel. The Chicxulub crater in Mexico is best known because of the extinction of the dinosaurs at the end of the Cretaceous period 66 million years ago.

Climate change threatens Lake Tanganyika in East Africa
Research from the Vrije Universiteit Brussel and UC Louvain warns of the effects of global warming on the fragile ecosystems of one of Africa's largest lakes. A rise of a few degrees in the water temperature can unbalance the ecosystem, with a major impact on local habitats as a result. "For our research, we combined a 3D hydrodynamic model of Lake Tanganyika made using SLIM-3D by Professor Eric Deleersnijder's research group at UC Louvain, with our own VUB expertise on climate modelling," says lead author Kevin Sterckx of VUB's Department of Hydrology and Hydraulic Engineering.

Climate change in oceanwater may impact mangrove dispersal
Climate change in oceanwater may impact mangrove dispersal
An international research led the VUB Biology Department examined 21 st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. The study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity.

Belgian research cracks mangrove puzzle
Belgian research cracks mangrove puzzle
VUB research uncovers factors that prevent mangroves from spreading in South America Mangrove ecosystems are distributed around the world, along tropical and subtropical coastlines. However, they do not extend beyond certain latitudes, even though the sites seem suitable for them. VUB researcher Ari Ximenes, with researchers from ULB and UCLouvain, has now cracked this question among mangrove bio-geographers, by studying sites off the eastern coast of South America.

Genetic defects can provide a long-term evolutionary advantage
Evolution seems to be a story of continual progress. The weak will perish, according to Darwin's law. Nevertheless, genetic defects that at first glance might make an organism weaker can increase its long-term chances of survival. At first sight, evolution seems to be a story of continual, step-by-step progress.

Lost silk road city located by Ghent University researcher
Lost silk road city located by Ghent University researcher
A researcher at Ghent University has identified a lost Silk Road city larger than medieval Ghent, London or Venice. Historians and archaeologists have been searching for nearly 200 years for the city of Magas, capital of the ninth to twelfth century kingdom of Alania. This Kingdom, located in the North Caucasus mountains of modern Russia, controlled a critical section of the Silk Roads: a trade route which connected East Asia and the Mediterranean centuries before the era of European expansion.

Plants play dominant role in landscape formation of coastal areas
Introduction: Dutch and Flemish researchers studied the colonisation by coastal vegetation Coastal vegetation interacts with water flow and the transport of sand and sediment: this interaction plays a key role in the rise of characteristic landscape forms in coastal habitats. Scientists from the University of Utrecht, the Netherlands Institute for Sea Research and University of Antwerp ( Global Change Ecology Centre , Research Group Ecosystem Management ) provide more insight in this interaction in their new paper that appeared recently.

Lavas in the lab could lead miners to new iron ore deposits
Geologists have discovered that some magmas split into two separate liquids, one of which is very rich in iron. Their findings can help to discover new iron ore deposits for mining. Iron ore is mined in about 50 countries, with Australia, Brazil and China as the largest producers. It is mostly used to produce the steel objects that are all around us - from paper clips to kitchen appliances and the supporting beams in skyscrapers.

Giant earthquakes: not as random as thought
Scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking into account smaller earthquakes, the repeat interval becomes increasingly more irregular to a level where earthquakes happen randomly in time. In their recent paper in Earth and Planetary Science Letters , Moernaut`s team of Belgian, Chilean and Swiss researchers presented a new approach to tackle the problem of large earthquake recurrence.
