Ancient rainfall records stretching 550,000 years into the past may upend scientists' understanding of what controls the Asian summer monsoon and other aspects of the Earth's long-term climate. Milankovitch theory says solar heating of the northernmost part of the globe drives the world's climate swings between ice ages and warmer periods. The new work turns Milankovitch in its head by suggesting climate is driven by differential heating of the Earth's tropical and subtropical regions.
Researchers at The University of Texas at Arlington have found a correlation between a strong immune response in diseased corals and a lower expression of genes associated with growth and reproduction.
Tropical Cyclone Mekunu, the second tropical cyclone in less than a week, formed in the western Arabian Sea early on May 22, 2018 and is moving toward a landfall in Oman. NASA satellites provided an infrared, night-time and precipitation analysis of the storm.
Ecologists have no doubt that climate change will affect the earth's animals and plants. But how exactly? This is often hard to predict. There are already indications that some species are shifting their distribution range. But it is much less clear how individual animals and populations are responding to the changes. Scientists at the UFZ have been studying nocturnal desert geckos to see how they are adapting to climatic changes.
Magma steadily emerges between oceanic plates. It pushes the plates apart, builds large underwater mountains and forms new seafloor. This is one of the fundamental processes that constantly change the face of the Earth. But there are also times when new seabed is created without any volcanism, by un-roofing mantle material directly at the seafloor. Scientists led by GEOMAR, Germany have published the first estimation based on seismic data on how much seafloor is produced this way.
Today, only the eldest inhabitants of the Danube Delta recall that, in the past, you could skate on the river practically every winter; since the second half of the 20th century, Europe's second-largest river has only rarely frozen over.
Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists from Cracow have proposed their own explanation of this phenomenon and presented predictions related to it, about consequences that are particularly interesting for high-energy neutrino astronomy.
A highly precise method to determine past typhoon occurrences from giant clam shells has been developed, with the hope of using this method to predict future cyclone activity.
A study published in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.
