    Seeing our world through the eyes of a migratory bird would be a rather spooky experience. Something about their visual system allows them to 'see' our planet's magnetic field, a clever trick of quantum physics, and biochemistry that helps them navigate vast distances. Now, for the first time ever, scientists from the University of Tokyo have directly observed a key reaction hypothesised to be behind birds', and many other creatures', talents for sensing the direction of the planet's poles. Importantly, this is evidence of quantum physics directly affecting a biochemical reaction in a cell – something we've long hypothesised but...

    As astronomers peering into Earth’s interior, there is no way for them to “feel” the true nature of the core. ... Scientists have long been on this quest, sometimes with fatal consequences. Explorers of old perished trying to set up monitoring stations in far-flung locales, like the doomed English explorer Sir John Franklin, whose expedition to take magnetic observations of the North Pole in 1845 ended with 129 men dead and two ships lost. As soon as long-lasting ground observatories sprung up around the world, scientists noticed strange deviations in the field, including for example, that our magnetic North and...

    What prompted this “massive, but localised compression”, which looked like something punched the magnetic field, is unclear. The edge of the bubble rushed towards the Earth by about 25,000 kilometres, taking just 1 minute and 45 seconds. The researchers suggested that there might have been an unprecedented storm in the area where the solar particles sneak through our protective bubble, the magnetosphere. What caused the storm is not known. "This motion is something that we've never seen before. This eastward and then westward and then spiralling motion is not something that we've ever seen, not something we currently understand", Briggs...

    Earlier this year, US National Oceanic and Atmospheric Administration and the British Geological Survey (BGS) were forced to update the World Magnetic Model a year ahead of schedule due to the speed with which the magnetic north pole is shifting out of the Canadian Arctic and toward Russia’s Siberia. The BGS and the US National Centers for Environmental Information has released a new update to the World Magnetic Model this week, confirming that the magnetic north pole, whose coordinates are crucial for the navigation systems used by governments, militaries and a slew of civilian applications, is continuing its push toward...

    In his book "2061 - Odyssey Three" (the third of his Space Odyssey series), Arthur C. Clarke put forward the intriguing proposal that the core of the planet Jupiter was, in fact, a diamond the size of Earth. Now Clarke, even though a science fiction author of some repute, had a science background and always tried to bring rigorous scientific accuracy to his stories. So, could his proposition be possible? The somewhat predictable answer is - we don't know. But we can analyse the possibility within known scientific parametres, to see if it is, at least, possible. For diamond to...

    Jupiter’s gravity field varies with depth, which indicated that material is flowing as far down as 3,000 km (1,864 mi). Combined with information obtained during previous perijoves, this latest data suggests that Jupiter’s core is small and poorly defined. This flies in the face of previous models of Jupiter, which held that the outer layers are gaseous while the interior ones are made up of metallic hydrogen and a rocky core. ... Another interesting find was that Jupiter’s gravity field varies with depth, which indicated that material is flowing as far down as 3,000 km (1,864 mi). Combined with information...

    Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought. “We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. "It was a long trip to get to Jupiter, but these...

    Scientists have found that increasing oxygen levels are linked to the rise of North American dinosaurs around 215 M years ago. A new technique for measuring oxygen levels in ancient rocks shows that oxygen levels in North American rocks leapt by nearly a third in just a couple of million years, possibly setting the scene for a dinosaur expansion into the tropics of North America and elsewhere... The US-based scientists have developed a new technique for releasing tiny amounts of gas trapped inside ancient carbonate minerals. The gases are then channelled directly into a mass spectrometer, which measures their composition....

    The researchers combined magnetic readings and radioisotope dating of samples from seven lava flow sequences to recreate the magnetic field over a span of about 70,000 years centered on the latest geomagnetic reversal. They accurately dated the lava flows by measuring the argon produced from radioactive decay of potassium in the rocks. They found that the final reversal was quick by geological standards, less than 4,000 years. But it was preceded by an extended period of instability that included two excursions — temporary, partial reversals — stretching back another 18,000 years. The lava flow data was corroborated by magnetic readings...

    An ancient tree that contains a record of a reversal of Earth's magnetic field has been discovered in New Zealand. The tree -- an Agathis australis, better known as its M&Ccedilori name kauri -- was found in Ngawha, on New Zealand's North Island, during excavation work for the expansion of a geothermal power plant, stuff.nz reports. The tree, which had been buried in 26 feet of soil, measures eight feet in diameter and 65 feet in length. Carbon dating revealed it lived for 1,500 years, between 41,000 and 42,500 years ago... The lifespan of the kauri tree covers a point...

    Rapid changes in the churning movement of Earth's liquid outer core are weakening the magnetic field in some regions of the planet's surface, a new study says. "What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field," said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen. The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said. The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the...

    During the experiment, 26 participants each sat with their eyes closed in a dark, quiet chamber lined with electrical coils. These coils manipulated the magnetic field inside the chamber such that it remained the same strength as Earth’s natural field but could be pointed in any direction. Participants wore an EEG cap that recorded the electrical activity of their brains while the surrounding magnetic field rotated in various directions. ...Joseph Kirschvink, a neurobiologist and geophysicist at Caltech, and colleagues studied alpha waves to determine whether the brain reacts to changes in magnetic field direction. Alpha waves generally dominate EEG readings...

    Earth’s Magnetic Field Decaying at an Alarming Rate December 11, 2018 | David F. Coppedge The biosphere depends on earth’s magnetic field, but it has been decaying rapidly for at least 1500 years. In Spacecraft Earth: A Guide for Passengers, Dr Henry Richter describes how the story of the decay of the earth’s magnetic field caught his attention. He had read the monograph by Dr Thomas Barnes in the 1970s, and realized the implications: if the decay is true, the earth could not be billions of years old. He considered the various proposals for maintaining the field, but none of...

    SAN FRANCISCO - The strength of the Earth's magnetic field has decreased 10 percent over the past 150 years, raising the remote possibility that it may collapse and later reverse, flipping the planet's poles for the first time in nearly a million years, scientists said Thursday.   At that rate of decline, the field could vanish altogether in 1,500 to 2,000 years, said Jeremy Bloxham of Harvard University. Hundreds of years could pass before a flip-flopped field returned to where it was 780,000 years ago. But scientists at a meeting of the American Geophysical Union cautioned that scenario is an...
