Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, the ERC remOcean project, led by researchers at the Laboratoire d'Océanographie de Villefranche (CNRS/UPMC), has developed a new class of robots: biogeochemical profiling floats, the first robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom.
President Donald Trump signed Executive Order 13769 on Jan. 27, 2017, effectively barring individuals from seven predominately Muslim countries from entering the United States for 90 days.
Within a day of his decree, thousands of protesters flooded airports around the country in opposition to what was quickly deemed a "Muslim ban," and by March 6, the order had been formally revoked.
Over 80% of people - 5.88 billion individuals - reside within one hour of a city. However, accessibility is not equally distributed across the development spectrum. While people live within one hour of a city in over 90% of cases in high-income countries - concentrated in Europe and North America - for low-income countries concentrated in sub-Saharan Africa, the figure is 50.9%.
The digital reconstruction of the skull of a 200-million-year-old South African dinosaur, Massospondylus, has made it possible for researchers to make 3D prints and in this way facilitate research on other dinosaurs all over the world.
Kimi Chapelle, a PhD student at the Evolutionary Studies Institute at the University of the Witwatersrand in Johannesburg, South Africa (Wits), has used the Wits MicroFocus CT facility to peer inside the skull of the dinosaur Massospondylus.
SAU AstroChallenge employees are convinced that this new map of medium-scale travelling ionospheric disturbances will help find out the reasons of the emergence of such phenomena in midlatitude areas. MSTIDs have not yet been thoroughly studied. They significantly impact the distribution of radio signals, so appropriate research is of great practical importance.
To do so, the researchers evaluated as yet unpublished data from the Agricultural Health Study (AHS) in the USA, the observation period of which had been extended by eleven years. Through the extended follow-up of the AHS, they come to the conclusion that no significant connections could be established between applications of plant protection products containing glyphosate and the occurrence of cancer among the examined population group.
Global warming affects more than just plant biodiversity - it even alters the way plants grow. A team of researchers at Martin Luther University Halle-Wittenberg (MLU) joined forces with the Leibniz Institute for Plant Biochemistry (IPB) to discover which molecular processes are involved in plant growth. In the current edition of the internationally renowned journal Current Biology, the group presents its latest findings on the mechanism controlling growth at high temperatures. In the future this could help breed plants that are adapted to global warming.
Women who consume Internet pornography are using technology to explore their sexuality and connect with others to discuss their sexual interests, according to research from the University of Waterloo.
Imagine trying to get close to your dinner only for it to be swept aside by your approach; this is the scenario faced by aquatic creatures every day as they try to snap up a tasty morsel. 'It is impossible to eat something underwater without creating a hydrodynamic disturbance', says Maria Wilson from the University of Southern Denmark, describing how a predator's approach is heralded by a bow wave that arrives before the final slurp as a hungry hunter sucks up its prey.
Water-saving measures in California have also led to substantial reductions in greenhouse gas (GHG) emissions and electricity consumption in the state.
That is the conclusion of new research from the University of California, Davis, published today in the journal Environmental Research Letters.
