Magnetic North Pole Is Moving Toward Russia at a Swift Pace, Confounding Scientists
Earth's magnetic north pole, which serves as an anchor point for our navigation has been actively moving east from the Canadian Arctic towards Russia, as CNN reported.
The magnetic north pole, unlike geographic poles, is capable of moving and has traveled about 1,400 miles since 1831. However, in recent years, the magnetic north pole has moved at a surprisingly swift pace, confounding scientists looking for an explanation, according to CNN.
The rapid movement of the magnetic north pole forced the researchers who create the World Magnetic Model (WMM) to create a new forecast a year ahead of schedule, according to the WMM press release. The WMM is maintained jointly by the National Oceanic and Atmospheric Administration and the British Geological Survey.

The magnetic north was moving so swiftly that the WMM released an interim update in February to avoid navigational or operational issues with the discrepancy between where the true magnetic north pole is and where the 2015 model pegged it to be, according to Forbes.
To figure out where the magnetic north is and to create the model, the researchers look at satellite data and data from 160 land-based observatories. The model is updated every five years, so the next one is due in 2025, as Phys.org reported.
The updated model, which is used by the civilian navigation systems the North Atlantic Treaty Organization and U.S. and British militaries, shows the magnetic north pole moving towards Siberia, though it has slowed its pace to 25 miles per year, or 40 kilometers per year, as Forbes reported.
To be clear, when a compass points north, it's pointing at the magnetic north pole, not the geographic pole. In recent years, the magnetic poles and the geographic poles have been closely aligned, but that has not always been the case, as Phys.org reported.
The location of the magnetic north pole stems from geological processes deep under the Earth's crust. The Earth's molten iron outer core moves as the planet spins. The flow of molten iron creates a magnetic field that determines the poles. The magnetic field also protects Earth from solar wind and charged particles from the sun, as Forbes reported.
From time-to-time the magnetic poles flip, meaning that the magnetic north pole is near the South Pole. While has happened a few times in Earth's history, it is a slow and arduous process that takes 22,000 years to complete, which researchers say is much longer than anticipated or expected, according to CNN. The last time polarity reversal took place was 770,000 years ago.
Scientists have figured out these reversals from rock records, ocean sediments, Antarctic ice cores and lava flows. Those samples show researchers how Earth's magnetic field has weakened, shifted, stabilized and reversed over a million years, according to CNN.
"Reversals are generated in the deepest parts of the Earth's interior, but the effects manifest themselves all the way through the Earth and especially at the Earth's surface and in the atmosphere," said Brad Singer, a University of Wisconsin-Madison geologist to CNN. "Unless you have a complete, accurate and high-resolution record of what a field reversal really is like at the surface of the Earth, it's difficult to even discuss what the mechanics of generating a reversal are."
As recently as 2000, magnetic north was moving at just six miles per year. While it has ramped up speed, the movement is unlikely to impact most people, though non-scientists may notice tweaks to GPS applications and runway markers at airports, as Phys.org reported.
Correction: This article has been corrected to reflect that as recently as 2000, magnetic north moved just six miles per year, not six miles per hour.

Home gardening is having a boom year across the U.S. Whether they're growing their own food in response to pandemic shortages or just looking for a diversion, numerous aspiring gardeners have constructed their first raised beds, and seeds are flying off suppliers' shelves. Now that gardens are largely planted, much of the work for the next several months revolves around keeping them healthy.
Start With Prevention<p>Just as preventive steps like maintaining a balanced diet help keep humans healthy, home growers can take many actions to help their gardens thrive.</p><p>One key step is assessing soil fertility – the ability of soil to sustain plant growth – which can vary widely depending on your location and soil type. Low soil fertility limits food production and predisposes plants to disease and pests. University extension <a href="https://soiltesting.wvu.edu/" target="_blank">soil testing labs</a> can help evaluate the quality of garden soil and identify nutrient deficiencies and acidic soils, often at no charge.</p>

Diagnosing Problems<p>Common plant pathogens include <a href="https://www.apsnet.org/edcenter/disandpath/viral/introduction/Pages/PlantViruses.aspx" target="_blank">viruses</a>, <a href="https://www.apsnet.org/edcenter/disandpath/prokaryote/intro/Pages/Bacteria.aspx" target="_blank">bacteria</a>, <a href="https://www.apsnet.org/edcenter/disandpath/nematode/intro/Pages/IntroNematodes.aspx" target="_blank">nematodes</a>, <a href="https://www.apsnet.org/edcenter/disandpath/oomycete/introduction/Pages/IntroOomycetes.aspx#:%7E:text=The%20oomycetes%2C%20also%20known%20as,foliar%20blights%20and%20downy%20mildews." target="_blank">oomycetes</a> and <a href="https://www.apsnet.org/edcenter/disandpath/fungalasco/intro/Pages/IntroFungi.aspx" target="_blank">fungi</a>. All of these microorganisms, especially at an early stage of infection, are too small to see. But when they proliferate, they cause changes in plants that we can recognize.</p><p>Unlike insects, which move around on six legs or on wings through the air, pathogens can move unseen and unchecked from leaf to leaf on the wind, through the soil or in droplets of water. Some microbes have even formed intimate relationships with insects and use them as vehicles to move from plant to plant, which makes these pathogens even more challenging to manage. Unfortunately, by the time some pathogens make their presence known, the damage is already done.</p><p>We recently conducted a <a href="https://twitter.com/kasson_wvu/status/1265989041725624323" target="_blank">Twitter poll</a> of gardeners nationwide to find out which culprits plagued their gardens. People named <a href="https://ento.psu.edu/extension/factsheets/aphids" target="_blank">aphids</a>, <a href="https://ento.psu.edu/extension/factsheets/squash-vine-borer" target="_blank">squash vine borers</a>, <a href="https://ento.psu.edu/extension/factsheets/squash-bug" target="_blank">squash bugs</a> and <a href="https://ento.psu.edu/extension/factsheets/flea-beetle" target="_blank">flea beetles</a> as the most problematic insect pests. Their most troublesome pathogens included <a href="https://extension.wvu.edu/lawn-gardening-pests/plant-disease/fruit-vegetable-diseases/powdery-mildew" target="_blank">powdery mildew</a>, <a href="https://plantpath.ifas.ufl.edu/rsol/Trainingmodules/BWTomato_Module.html" target="_blank">tomato bacterial wilt</a> and <a href="https://extension.wvu.edu/lawn-gardening-pests/plant-disease/fruit-vegetable-diseases/downy-mildew" target="_blank">cucurbit downy mildew</a>.</p><p>To manage such perennial challenges, the first step is to spend time closely looking at your plants. Do you notice any insects consistently hanging around, or molds colonizing leaves or other plant parts? How about symptoms such as blight, stunting, or leaves that are yellowing, browning or wilting?</p>

The effects of climate change may more far-reaching than you think.
Hotter temperatures have been linked to a rise in energy poverty, with more people struggling to meet their energy bills from their household income, according to a new study published on ScienceDirect by researchers from Italy's Ca' Foscari University.

As if the surging cases of coronavirus weren't enough for Floridians to handle, now the state's Department of Health (DOH) has confirmed that a person in the Tampa area tested positive for a rare brain-eating amoeba, according to CBS News. The Florida DOH posted a warning to residents to remind them of the dangers of the rare single-celled amoeba that attacks brain tissue.

The World Health Organization (WHO) is holding the line on its stance that the respiratory droplets of the coronavirus fall quickly to the floor and are not infectious. Now, a group of 239 scientists is challenging that assertion, arguing that the virus is lingering in the air of indoor environments, infecting people nearby, as The New York Times reported.
