In Senegal, a 2,000‑year‑old iron workshop sheds new light on the past
In Senegal, a 2,000‑year‑old iron workshop sheds new light on the past Lisa Lock Scientific Editor Andrew Zinin Lead Editor How was iron produced 2,000 years ago in Senegal? A recent study at the Didé West 1 archaeological site, in the Falémé Valley in eastern Senegal, sheds light on an ancient iron production technique. Passed down from generation to generation for nearly eight centuries, this technology appears to have been developed to meet local needs.
Iron Age Britons may have removed the brains of the dead
A woman interred in Scotland 2000 years ago has peculiar scrape marks inside her skull, which suggest that removing the brain after death may have been a funeral tradition in Iron Age Britain. The funerary practices in Iron Age Britain – which ran from about 800 BC until the Roman invasion of Britain in AD 43 – and the Iron Age more generally are mysterious because human remains from that long ago rarely survive. We do know that some people from this time tended to be buried alongside their...
How drought rewires roots, cutting iron uptake across major food crops
How drought rewires roots, cutting iron uptake across major food crops Sadie Harley Scientific Editor Robert Egan Associate Editor New research by scientists at the University of Calgary has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. It's a finding that could have implications for the nutritional value of agricultural crops. The study, published in the journal Cell, questions whether plants...
Iron-deficiency in the tumor microenvironment reprograms tumor-immune interactions in a sex biased manner
Background: Glioblastoma (GBM) is a sex-biased disease characterized by higher incidence and poorer survival in males. These sex differences are primarily driven by metabolic and immune signatures, with iron metabolism playing a major role. While iron is essential for tumor cell proliferation, it is also critical for T cell recruitment and function within the tumor microenvironment (TME).
Effects of preferential concentration on the combustion of iron particles -- A numerical study with homogeneous isotropic turbulence
arXiv:2604.04048v2 Announce Type: replace Abstract: Iron particles, with their non-volatile combustion mode, remain in the dispersed phase throughout the combustion process, causing the flow in a typical iron powder combustor to be particle-laden and turbulent. Preferential concentration is a phenomenon prevalent in such turbulent flows that causes particle clustering. To estimate the effects of clustering on the combustion process, direct-numerical-simulations are performed on a cubical...
Scientists say guava juice could make iron supplements work better
Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice — especially with iron supplements — experienced noticeable increases in hemoglobin levels. Since guava contains far more vitamin C than oranges, scientists believe it could become a simple, affordable nutrition tool in regions where anemia is widespread.
Space station dust maps slash climate uncertainty over iron-rich particles
Space station dust maps slash climate uncertainty over iron-rich particles Lisa Lock Scientific Editor Robert Egan Associate Editor New research from a team of scientists led by Cornell is transforming how researchers understand one of the atmosphere's most abundant and least understood constituents: mineral dust. Mineral dust, composed of tiny particles lifted from arid regions including the Sahara, Middle East and East Asia, plays a complex role in Earth's climate system. These particles...

Demonstrating magnetic memory in iron-rhodium structures using a quantum diamond microscope
arXiv:2606.03738v1 Announce Type: cross Abstract: Iron-rhodium (FeRh) has a first-order phase transition near room temperature between antiferromagnetic (AFM) and ferromagnetic (FM) phases, making it a promising material for magnetic memory technologies like heat-assisted magnetic recording (HAMR). It has a comparatively sharper phase transition and lower writing temperature than alternative materials, implying less thermal engineering constraints and an increase in write/read head lifetime....
