  • Scientists Find Vast Reservoir of Water Deep Below Earth’s Surface

    Scientists Find Vast Reservoir of Water Deep Below Earth’s Surface

    Scientists have made an amazing discovery about water deep inside the Earth. They found that there could be several oceans’ worth of water trapped way below our feet, about 400 miles down. This discovery challenges what we knew about how water is spread out on our planet. The scientists found a special mineral called ringwoodite that helped them make this discovery.

    water deep

    The researchers who found this water are Steve Jacobsen from Northwestern University and Brandon Schmandt from the University of New Mexico. They shared their discovery in a journal called Science. This discovery tells us more about how the Earth formed, what it’s made of, and how much water is stuck inside rocks deep below us.

    Jacobsen explained that what happens deep inside the Earth affects what we see happening on the surface like earthquakes and volcanoes. He said that this discovery might help explain why there is so much water on Earth’s surface. Scientists have been trying to find this hidden water for a long time.

    The scientists knew that there might be water deep in the Earth’s mantle, which is a layer between the upper and lower parts of the mantle, about 250 to 410 miles below us. But Jacobsen and Schmandt are the first ones to find proof of water on a big scale in this part of the Earth, especially under the United States.

    The water they found isn’t like what we’re used to seeing on the surface. It’s not liquid, ice, or vapor. Instead, it’s trapped inside the minerals in the mantle rock. The extreme pressure and heat deep down cause water molecules to split and form something called hydroxyl radicals, which then get stuck in the mineral’s crystal structure.

    One special mineral called ringwoodite is what helped them find this water. It’s a blue mineral that forms deep in the mantle, about 250 to 410 miles below us. Ringwoodite can store water inside its crystal structure. Jacobsen has been able to make this mineral in his lab, and he found that it can hold more than one percent of its weight in water.

  • Earth’s Mystery: Scientists Discover Massive Solid Metal Ball at Core

    Earth’s Mystery: Scientists Discover Massive Solid Metal Ball at Core

    When it comes to understanding the planet we call home there is always something new to learn even for those of us who didn’t excel in science class. For years, there has been speculation about what lies within Earth’s core. While many people may assume it is just a solid round ball, but recent discoveries challenge that particular theory.

    Metal Ball

    Their unique approach allowed them to study the core in unprecedented detail and it was leading to the identification of a solid metal core. It is also known as an ‘innermost inner core’ or IMIC. This solid metal core was estimated to be around 800 miles in diameter and it constitutes nearly one percent of Earth’s volume. It is a much larger size than previously predicted.

    Last July, seismologists at the Australian National University made a groundbreaking revelation and it is a solid metal ball exists right at the center of Earth’s core. Through their studies of earthquakes and seismic waves traveling through the planet, scientists Thanh-Son Phạm and Hrvoje Tkalčić discovered this solid metal core, which they believe formed after a significant global event in the distant past.

    Phạm and Tkalčić propose that the metal inner core could serve as a ‘fossilized record’ of a significant tectonic event, offering insights into Earth’s evolutionary processes. Their findings underscore the importance of studying Earth’s core, not just for academic curiosity but also for understanding the fundamental mechanisms shaping life on our planet.

    According to Phạm, the solid metal core differs from the outer layer of the core in terms of atomic arrangement, suggesting it may possess distinct properties affecting the speed of seismic waves passing through it. Our researchers speculate that this solid metal core could hold vital clues about Earth’s history and the evolution of life on the planet’s surface.

     

  • Dark Matter: Scientists Consider Alternative Theories with ‘Mirror Universe’

    Dark Matter: Scientists Consider Alternative Theories with ‘Mirror Universe’

    Scientists are exploring the possibility of a ‘mirror universe’ as a potential explanation for the elusive dark matter that remains undetected in our universe. This theory proposes that dark matter exists in a parallel realm, where atoms failed to form during the Big Bang’s nucleosynthesis.

    Dark matter

    Dark matter is thought to make up about 85% of the universe ‍and it has puzzled scientists due to its invisibility and resistance to detection. Traditional theories have fallen short in explaining its nature which leads researchers to consider alternative ideas. One such theory suggests the existence of a ‘dark mirror’ universe where dark matter resides.

    In this hypothetical scenario, every interaction in our universe would have a corresponding interaction in the dark matter universe establishing a new kind of universal symmetry. While conventional matter in our universe consists of protons and neutrons with roughly equal mass, the ‘dark mirror’ universe may feature different properties, potentially leading to the formation of ‘dark neutrons’ instead of protons.

    The concept proposes that these ‘dark neutrons’ could form bound states and larger nuclei during a hypothetical ‘dark Big Bang Nucleosynthesis.’ These nuclei, composed of pure ‘dark neutrons,’ could serve as valid candidates for dark matter.

    This idea builds upon previous research suggesting the existence of a ‘dark periodic table’ with its own set of elements in the ‘dark mirror’ universe. While speculative, this theory offers a new perspective on the nature of dark matter and its potential origins.

    Some scientists have proposed that stars composed of dark matter could exist in this alternate universe. These ‘dark matter’ stars might interact differently with normal matter, offering a potential means of observation. The existence of such stars remains uncertain, and their detection would require further investigation.

  • Scientists Worried as Iceland Faces Fourth Volcanic Eruption in Recent Months

    Scientists Worried as Iceland Faces Fourth Volcanic Eruption in Recent Months

    Iceland’s volcano has become active once again and it is marking the fourth eruption in just three months. The eruption occurred in the evening local time on Saturday, with lava spewing out through a three-kilometer-long fissure and advancing towards the nearby area. Authorities are expressing concerns and they are noting that such a significant lava flow has not been witnessed by Icelanders since the 8th century.

    volcano

    The Meteorological Department had previously issued warnings about the high likelihood of an eruption from the volcano. Lava began erupting on Saturday evening local time and it was advancing rapidly towards inhabited areas, prompting the evacuation of hundreds of tourists and residents to safety. Many individuals, including diners at local restaurants, found themselves in a terrifying situation as they fled from the advancing flames.

    It is sparking fears of entering an era of serial eruptions. The volcano is fiercely ablaze, evident from the roaring sound audible kilometers away. Extensive areas are now submerged under fiery lava, with a long rift visible between the mountains from which the burning lava is emanating.

    This recent eruption marks the fourth in a series of volcanic activities within a span of three months and it is raising concerns about a return to ancient times characterized by frequent eruptions. While eruptions are not uncommon in Iceland, the volume of lava observed during the past two eruptions has been unprecedented in the last 800 years, puzzling scientists about the underlying causes.

    Iceland is situated between two opposing tectonic plates and it experiences  the frequent earthquakes, often triggering volcanic activity. Consequently, the region’s volcanoes are known to awaken regularly, earning them the designation of volcano hotspots. Over time, the distance between the tectonic plates tends to increase, exacerbating the situation with each passing day.

    With over a hundred volcanoes in the country, approximately 30 are currently active. Should a series of eruptions ensue, Iceland’s future could be jeopardized, raising significant concerns among scientists regarding the country’s stability and safety.

    Scientists have made a remarkable discovery in the realm of superconductors.  The identification of miassite as the world’s first ‘unconventional’ superconductor marks a significant milestone in scientific research. This discovery not only challenges existing theories but also paves the way for groundbreaking advancements in superconductor technology and its applications.

    Superconductor

    These materials capable of conducting electricity with zero resistance. Among the limited number of superconductors found in nature, researchers have identified the world’s first ‘unconventional’ superconductor. Already widely utilized in technologies like MRI scanners and particle accelerators, superconductors offer promising prospects for further advancements.

    An international team of scientists recently found that the mineral miassite, known for its superconducting properties, demonstrates characteristics of an unconventional superconductor. This discovery is remarkable considering miassite’s occurrence in nature, as opposed to being solely synthesized in laboratories.

    Superconductors are prized for their ability to carry electric current without any loss of energy and it is achieved through the formation of Cooper pairs where electrons pair up and navigate through the material effortlessly. Unlike conventional superconductors, unconventional ones exhibit unique properties, often appearing at higher temperatures.

    While miassite found naturally may not possess the necessary purity for unconventional superconductivity, laboratory-synthesized miassite holds promise for future applications. The researchers employed various tests to confirm miassite’s unconventional superconductivity, including the London penetration depth test and examinations of material defects.

    Miassite is composed of rhodium and sulfur elements, intrigued researchers due to its unique combination of properties. This discovery opens up new avenues for advancing quantum science and exploring the potential applications of unconventional superconductors.

    Paul Canfield is a physicist from Iowa State University and he highlighted the significance of the discovery, likening it to finding a hidden treasure trove. Miassite, along with other newly discovered superconductors, holds immense potential for future technological innovations.

  • Polar Vortex: Scientists Warn of Rapid Polar Temperature Changes

    Polar Vortex: Scientists Warn of Rapid Polar Temperature Changes

    Polar Vortex, a concerning phenomenon, is making headlines lately, worrying scientists. They’ve been warning about rapid temperature changes in the polar regions, and recent events like a sudden cold spell in New Hampshire have raised alarms.

    Polar Vortex

    In 2019, extreme cold in the US Midwest claimed 21 lives. It was so cold that boiling water instantly froze when exposed to the outside air. America has faced similar cold periods in the past, like in 1977, 1982, 1985, 1989, and 2014.

    Scientists are using advanced technology like computer algorithms, satellites, and weather balloons to study the vortex in detail. During a cyclone, the weather can suddenly turn very cold, causing drastic changes in the atmosphere.

    These catastrophic events are linked to climate change and global warming. As the temperature gap between central and polar regions shrinks, polar air flows more towards the south. This can lead to extreme cold, snowstorms, and winter storms in unexpected places, posing risks to human life and disrupting transportation systems.

    Scientists worry that such events may not only affect America but also Europe and Canada. To prevent this, reducing arctic temperatures, increasing the use of renewable energy, and cutting greenhouse gas emissions are crucial steps. This will help lessen the occurrence of these dangerous weather patterns.

  • Scientists Discover Young and Close Earth-Sized Planet in Our Solar Neighborhood

    Scientists Discover Young and Close Earth-Sized Planet in Our Solar Neighborhood

    A group of scientists has found a planet that is closer and younger than any other Earth-sized planet identified so far. This planet, described in a recent study published in The , presents a unique opportunity for researchers to understand how planets evolve.

    Earth-sized planet

    The study was co-led by Melinda Soares-Furtado, a NASA Hubble Fellow at the University of Wisconsin-Madison, and Benjamin Capistrant, a graduate student at the University of Florida and recent UW-Madison graduate. The research team, which included UW-Madison graduate student Andrew C. Nine, undergraduate Alyssa Jankowski, and astronomy professor Juliette Becker, believes that HD 63433d, the newly discovered planet, offers valuable insights.

    Situated closer and younger than other Earth-sized planets, HD 63433d orbits a youthful star that is visible from both the Northern and Southern hemispheres. This positioning allows a higher number of instruments, such as the South African Large Telescope and the WIYN Observatory in Arizona (both designed and built with UW-Madison’s assistance), to observe the system. Additionally, the proximity of the star offers opportunities to develop novel methods for studying gases escaping from the planet’s interior and measuring its magnetic field.

    Melinda Soares-Furtado expressed excitement about the discovery, calling it “our solar backyard.” She emphasized the potential for learning from a star this close and with such a crowded planetary system. The researchers aim to gather information that will contribute to future studies of similar stars in the young group to which HD 63433d belongs.

  • Self-Healing Metals: How Copper and Platinum Surprise Scientists

    Self-Healing Metals: How Copper and Platinum Surprise Scientists

    Some metals have surprised scientists by showing the ability to heal themselves, which is not something typically seen in metals. Usually, when metals break, they remain broken unless something external fixes them. However, recent research suggests that certain metals, like copper and platinum, can naturally mend on their own, a discovery that could have significant implications for engineering both on Earth and in space.

    metals

    The discovery came about by accident when materials scientists from Sandia National Laboratories and Texas A&M University were studying copper and platinum at a very tiny scale. They used a special microscope to subject the metals to tiny proddings, similar to a mosquito’s legs walking, at a rate of 200 taps per second. Despite the small amount of pressure, the metals developed small cracks over time.

    These kinds of cracks are common daily, leading to failures in structures like electronic devices, vehicle engines, and bridges. The failures result in replacement costs, lost time, and sometimes even injuries or loss of life. However, in this experiment, something remarkable happened—within 40 minutes, both the platinum and copper samples healed as if the cracks were never there.

    This ability to heal contradicts what scientists previously thought about metals. Cracks were expected to grow larger, not smaller. The healing process was contrary to basic equations describing crack growth. The discovery confirmed a theory proposed a decade ago by Michael Demkowicz, a materials sciences and engineering professor at MIT. His computer simulations suggested that, under certain conditions, metals could hypothetically mend stress-induced cracks. The key to this ability lies in “cold welding,” where the sides of two cracks press into each other under specific conditions.

    Although much more research is needed to understand this phenomenon fully, the implications could be significant. It might change how engineers design and construct buildings, vehicles, and other structures. The experiments were conducted in a vacuum, but scientists hope to determine if metal cold welding could occur in normal atmospheric conditions.

    In any case, this discovery serves as a reminder that materials can behave unexpectedly under the right circumstances. As scientists continue to explore and understand these properties, we may unlock even more remarkable abilities in various materials.
