  1. Magnetism in Animals

    Magnetism in Animals
    Birds, amphibians & reptiles, and marine animals navigate by sensing changes in Earth’s magnetic field. We already know life on Earth is dependent on its magnetic field thanks to the powerful electrical currents it creates, and scientists have proven that some animals use magnetic sense, but we wanted to dig deeper into the why and how magnetic fields are so important to keep animals going where they need to go.  Continue reading →
  2. New Study Suggests The End of the Lunar Dynamo Happened 1B Years Ago

    New Study Suggests The End of the Lunar Dynamo Happened 1B Years Ago
    The moon is known to have likely lost its magnetic field after an internal dynamo stopped firing, the question has remained, however, of when. A team led by Said Mighani from MIT’s Department of Earth, Atmospheric, and Planetary Sciences, and Huapei Wang from the China University of Geosciences, have been studying the moon’s magnetic field for several years, and think they found an answer.  Continue reading →
  3. Magnetic Field May Improve Frozen Avocado Puree Properties

    Magnetic Field May Improve Frozen Avocado Puree Properties
    Does anyone really know the lifespan of an avocado? It feels like one minute it’s hard as a rock and then the next it’s mushy and too ripe.  If you’re a fan of avocados and haven’t nailed down the ripeness timing, freezing them can be a great way to extend the shelf-life of food, but, the quality post-thawing is sometimes inferior. Scientists Yamei Jin and Zhengjun Xie from Jiangnan University in China may have found an answer: adding a magnetic field in the freezing process.  Continue reading →
  4. Magnetars are the Strongest Magnet in the Universe. Here’s Why.

    Magnetars are the Strongest Magnet in the Universe. Here’s Why.
    In 1947, the idea that some massive stars could have large-scale magnetic fields near their surface was established, but the origin of these fields has since remained a mystery. Today, it’s known that the strongest magnetic fields ever detected in the Universe come from magnetars, but we still aren’t sure where these magnetars come from or how they get their strong magnetic fields. Though, astrophysicists Sebastian Ohlmann from the Max Planck Society in Germany and Friedrich Röpke from the Heidelberg Institute for Theoretical Studies in Germany may have found out how magnetars form.  Continue reading →
  5. Sea Turtles Find Their Birthplace with Magnetic Fields

    Sea Turtles Find Their Birthplace with Magnetic Fields
    Previous studies have shown that sea turtles use Earth’s magnetic field to help guide them at sea, similar to how sailors use latitude and longitude. Loggerhead turtles, in particular, have been known to swim thousands of miles to lay their eggs on Florida’s Gulf, as well as Atlantic coasts. What’s interesting is that recent research has found that these nesting places are actually within about 40-50 miles of where the turtles were born decades earlier.  Continue reading →
  6. Explaining Magnet Usage in the Netflix Original Stranger Things

    Explaining Magnet Usage in the Netflix Original Stranger Things
    Spoilers ahead if you haven’t finished watching Season 3 of Stranger Things! When a television show makes science references, they can either go over our heads or have us thinking “is that really true?”    We wrote a previous article about magnetic properties being discussed in the show: when the characters noticed things were going wrong, something “strange” was happening with their compass -- the needle was no longer pointing true North (though, it should be pointed to magnetic North). In this particular episode, they did an experiment and found that all of the compasses were deviating from pointing north, showing a very strong magnetic interference going on. We decided, for the most part, this event could be “real.”  Continue reading →
  7. The University of Iowa Wins a Record Grant to Study Magnetic Fields

    The University of Iowa Wins a Record Grant to Study Magnetic Fields
    There have been exciting things happening in magnetism. NASA recently awarded the University of Iowa (UI) a significant grant—$115 million—to study the interactions between the Earth and Sun’s magnetic fields. The TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) project, the largest research project in the university’s history, will be part of NASA’s Explorers Program.  Why Study the Magnetic Fields...
  8. Tate Features Pioneering Greek Sculptor’s Magnetic Work

    Tate Features Pioneering Greek Sculptor’s Magnetic Work
    Greek sculptor Takis -- born Panayuitis Vassilakis -- is a nonagenarian (a person who is between 90 to 99 years old!) and is the subject of an art exhibition opening on July 3 at Tate Modern in London. Why are we sharing this?  His work is about magnetism!  About Takis Works Takis was an avant-garde artist of the ‘50s and...
  9. This Superconducting Magnet Just Broke The Strongest Magnetic Field Record

    This Superconducting Magnet Just Broke The Strongest Magnetic Field Record
    A new superconducting magnet, created by National High Magnetic Field Laboratory (MagLab) at Florida State University, has briefly sustained a record-breaking 45.5-tesla magnetic field intensity. MagLab also produced the world’s previous strongest continuous field intensity, which held the top spot at 45-tesla since 1999.  To put this into perspective, the magnetic field intensity of a standard fridge magnet is about...
  10. How the Moon Got "Sunburns" - Solar Wind and Magnetic Fields

    How the Moon Got "Sunburns" - Solar Wind and Magnetic Fields
    As we all know, the Sun is powerful. So powerful that any object, person, or planet traveling through space is susceptible to the Sun’s damaging radiation. The latest victim to feel the Sun’s fiery wrath? Earth’s Moon. Researchers, using data from NASA’s ARTEMIS mission, have reported finding “distinctive patterns of darker and lighter swirls” on the Moon’s surface. When looking into it further, they have found that these swirls may actually be “sunburns.” Should we be worried about these sunburns on Earth? Continue reading →
