Red meat has been a part of diets worldwide since early man. It is an excellent source of protein, vitamins (such as B vitamins) and minerals (such as iron and zinc). However, red meat has long been associated with increasing the risk of heart disease, cancer and early death. What may not be so well known is the link between red meat consumption and type 2 diabetes.

A paper published in The Lancet in September 2024 highlighted this link to type 2 diabetes using data from the Americas, the Mediterranean, Europe, south-east Asia and the Western Pacific (20 countries included).

This recent study, with nearly 2 million participants, found that high consumption of unprocessed red meat, such as beef, lamb and pork, and processed meat, such as bacon, sa...

After its “birth” in the Big Bang, the universe consisted mainly of hydrogen and a few helium atoms. These are the lightest elements in the periodic table. More-or-less all elements heavier than helium were produced in the 13.8 billion years between the Big Bang and the present day.

Stars have produced many of these heavier elements through the process of nuclear fusion. However, this only makes elements as heavy as iron. The creation of any heavier elements would consume energy instead of releasing it.

In order to explain the presence of these heavier elements today, it’s necessary to find phenomena that can produce them. One type of event that fits the bill is a gamma-ray burst (GRB)—the most powerful class of explosion in the universe...

A multi-institution study led by Rohan Dharmakumar, PhD, of Indiana University School of Medicine, has identified that iron drives the formation of fatty tissue in the heart and leads to chronic heart failure in about fifty percent of heart attack survivors. The discovery, recently published in Nature Communications, paves the way for treatments that have the potential to prevent heart failure in nearly half a million people a year in the United States, and many millions more worldwide.

“For the first time, we have identified a root cause of chronic heart failure following a heart attack,” Dharmakumar said.

Dharmakumar is executive director of IU’s Krannert Cardiovascular Researc...

Researchers at the University of Oxford uncover the importance of iron for the development of complex life on Earth – which also may hint at the likelihood of complex life on other planets.

Iron is an essential nutrient that almost all life requires to grow and thrive. Iron’s importance goes all the way back to the formation of the planet Earth, where the amount of iron in the Earth’s rocky mantle was ‘set’ by the conditions under which the planet formed and went on to have major ramifications for how life developed...
