Capturing water from the clouds to combat water shortages in deserts
Affordable, effective and sustainable "fog nets" to capture droplets and combat water scarcity in deserts. An article by Denis Terwagne, Professor and Chairman of the Centre de Recherche en Physique, Faculty of Science, in The Conversation. In 2022, 2.2 billion people still have no access to drinking water services.

James Webb Space Telescope detects water vapour, sulfur dioxide and sand clouds in the atmosphere of a nearby exoplanet
A team of European astronomers, co-led by researchers from the Institute of Astronomy, KU Leuven, used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they discovered not only water vapour and sulfur dioxide, but even silicate sand clouds.

Fine particulates signalled the end of the dinosaurs
Fine dust from pulverised rock released by the impact of the Chicxulub meteorite 66 million years ago played a major role in climate cooling, disruption of photosynthesis and the mass extinction of dinosaurs, VUB researchers have found. Until now, the exact circumstances surrounding the mass extinction of the dinosaurs - such as the effect on the global climate of the material ejected by the meteorite's impact - have been unclear.

Fine particles heralded the end of the dinosaurs
Fine dust from pulverized rock released by the Chicxulub meteorite impact 66 million years ago played a dominant role in the cooling of the climate, the disruption of photosynthesis and the mass extinction in which most dinosaurs went extinct. Until now, the precise circumstances of the mass extinction, such as the effect of the different types of impact material ejected from the crater on global climate were unclear .

Alaska: record degradation in just 5 years
While Europe has been hard hit by global warming (floods, forest fires), with temperatures still abnormally high for October, the phenomenon is also being observed in Alaska, where 3 researchers from UCLouvain are currently pursuing their research on permafrost (or permafrost) during the summer-winter transition.

’Handbag ai funghi’: VUB team creates first sustainable handbag from mycelium leather
A team of biologists, bioengineers, architects and product developers at the Vrije Universiteit Brussel has developed the first fully bio-based and biodegradable handbag based on mycelium. Mycelium is the root structure of fungus and forms a tight network of white filaments in the soil, on wood or other organic material.

The beginning of the end for hydropower in Africa?
Hydropower, traditionally one of Africa's most important sources of electricity, is expected to rapidly lose out in importance in favour of solar power in the coming years. The attractiveness of new hydropower stations is declining, due to increasing economic competition from solar panels and ongoing uncertainty over the effects of climate change on river flows.

Tree rings show that it’s never been so hot in the last 1,200 years
The Middle Ages were tumultuous in climatic terms. It saw a cold phase, the Little Ice Age, and a warming period, the Medieval Climatic Optimum. The latter, according to data reconstructed from tree rings, saw temperatures sometimes higher than today's in northern Europe. This is an enigma: physics cannot explain this period of exceptional warmth, and climate models calculate more moderate temperatures for the period between the 10th and 14th centuries.

Greenland’s geological past provides clues to current global warming
Sediments taken from beneath an ancient ice core reveal that at least 20% of Greenland was green 416,000 years ago, corresponding to a recent past on the geological scale. The study, published in the journal Science, was carried out by an international team of scientists, including the Laboratoire de Glaciologie of the UniversitÚ Libre de Bruxelles.

VUB PhD research: early microbial ancestor of humans loved extremes and can teach us about origin of life on Earth
Archaea, representing a group of primordial microbes which were recently found to be very related to humans, often grow best in extreme environments. While many bacteria (which are standing very far from us from a evolutionary point of view) can withstand only small fluctuations in temperature and acidity, Archaea are true survival champions.

Researchers calculate evolution of brain tumours and sea levels
David Tewodrose and Harry Zekollari are two of 13 researchers to receive a prestigious Odysseus grant, a start-up fund from the Research Foundation - Flanders (FWO). They will be based at the Vrije Universiteit Brussel for the next five years to develop their research practice. Tewodrose focuses on geometric analysis that is used in medical applications, among other uses.

Researchers aim for first in-depth study of historic and prehistoric terrace building
We all know the images of Southeast Asia's vast rice fields neatly terraced against the hills. In Europe too, there used to be terraces, mostly bordered by hedges, which have been overtaken as agricultural practices have been scaled up. Archaeologists and geomorphologists from VUB and KU Leuven are now studying the typology of those terraces.

Capturing Shooting Stars
It is fascinating to see a streak of light across the sky, and never more so than those times of the year when the meteors fall to earth in such a multitude that they look like sparkling rain. The Geminid shower is such an event. Our researchers observed such -shooting stars- falling from the sky at their peak in mid-December thanks to cameras newly installed on top of one of the university buildings.

Antarctica by sailboat
In a few weeks, Belgian researchers, led by Professor Bruno Danis (Laboratory of Marine Biology, Faculty of Science, ULB), will set sail for Antarctica. Their objective is to contribute to our understanding of the responses of ecosystems to the environmental changes underway in the Southern Ocean. Originality: the mission will take place on..

Open Science for water research
For the launch of the new scientific journal Nature Water , researchers Emma and Stan Schymanski contributed an article about the future of water research. This opinion paper focuses on the importance of open science in a field where, due to its global societal relevance, knowledge and research results should be freely accessible by a wide range of stakeholders.

Efficiency of solar cells directly linked to R&D efforts
Professor Phillip Dale of the University of Luxembourg and Professor Mike Scarpulla of the University of Utah have discovered that researchers improve the efficiency of solar cells, the constituents of photovoltaic panels, at the same rate independently of the technology over the last decades.

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.

Active lipids enable intelligent swimming under nutrient limitation
Biophysicists from the University of Luxembourg have uncovered how microplankton - key photosynthetic organisms which produce nearly 50% of the oxygen we breathe - adopt a thrifty lifestyle when nutrients turn limiting. They strategically harness internal lipids to regulate swimming properties to maximise their fitness.

Unknown mangrove forest
Study is first to predict impact of climate change on mangrove distribution in South Africa A team of scientists from the Vrije Universiteit Brussel, Nelson Mandela University, the Moss Landing Marine Laboratories and the University of the Western Cape has been able to show for the first time that ocean currents and coastal geomorphology may continue to hold back the spread of mangrove forests along the South African coast, even as global warming creates a more ideal climate for them.
