The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, ...

An independent 2026 ranking highlights NUTRAHARMONY iron capsules and liquid drops among top-rated products in the iron ...

Which liquid iron supplements are best? While most people get the iron they need from their diet, certain conditions or illnesses may increase your risk of a deficiency. This makes it necessary to use ...

For four years, NASA's InSight lander recorded tremors on Mars with its seismometer. Researchers at ETH Zurich collected and analyzed the data transmitted to Earth to determine the planet's internal ...

Iron is the most abundant element by mass on Earth. Despite being so common and well-studied, iron still manages to puzzle scientists by exhibiting electric and magnetic behaviors that are not fully ...

Iron deficiency is one of the most common nutrient gaps worldwide, and it doesn’t just affect one group. Low iron levels are closely linked to fatigue, poor concentration, weakened immunity, and ...

Iron is an essential nutrient, and yet at least 1 in 5 women of reproductive age and 4 in 10 pregnant people in the UK are iron deficient. Including me. For most people, eating a balanced diet – one ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.

Two new innovative methods describe how to measure the electrical resistivity of liquid iron -- such as that found in planetary cores -- at extremely high pressures and temperatures. Prior to this, ...
