How ‘Iron Man’ bacteria could help protect the environment

This Geobacter cell—which looks a bit like a gray peanut in this microscope image—is speckled with a dark coating of cobalt minerals that would be toxic to many organisms.

How ‘Iron Man’ bacteria could help protect the environment — ScienceDaily

When Michigan State University’s Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not “environmentally relevant.” As other reviewers and the program manager didn’t share this sentiment, NSF funded the proposal. And, now, Reguera’s team has shown that microbes are capable of an […]

Iron infusion proves effective to treat anaemia in Rural Africa

In sub-Saharan Africa, anaemia is a major public health concern with roughly 60% of the population suffering from anaemia. Around half of those cases are due to iron deficiency. […]

Hungry plants rely on their associated bacteria to mobilize unavailable iron

IMAGE: In iron-limiting soils, plants activate an iron-deficiency response that includes production and secretion of coumarins. These compounds alter the composition of the root microbiota and elicit a microbial activity that… view more  Credit: Christopher J. Harbort In nature, healthy plants are awash with bacteria and other microbes, mostly deriving from the soil they grow in. […]

How Long Does Iron Linger in the Ocean’s Upper Layers?

Iron is in our blood, our buildings, and our biomes. In our oceans, iron has helped regulate global climate by sustaining carbon-catching phytoplankton. However, current environmental models have difficulty pinning down the relationship between climate and marine iron cycling because they have little data to go on. In new research, Black et al. […]

Zero-valent Iron in the Oxidizing Atmosphere?

The presence of iron in the atmosphere has significant implications for global nutrient delivery, human health, and several chemical cycles. Globally, the primary source of iron in the atmosphere is wind-blown dust from arid environments. However, in urban areas, iron is also produced via various combustion processes such as power generation and vehicle […]

You can’t squish this ‘iron’ beetle. Now, scientists know why.

Diabolical ironclad beetles are almost unbreakable — you can smack them, stomp on them or run them over with a car, and they’ll scamper away uncrushed. Now, scientists know why these beetles’ outer wing cases, known as elytra, are so tough — they’re made up of a series of smoothly interlocking puzzle parts; the geometry […]

Unburied victims’ bones reveal an Iron Age massacre in Iberia

Attacked from behind and at times dismembered, the fallen residents of an ancient Iberian village add to evidence that prehistoric Europe was a violent place. Violence in ancient Europe isn’t unheard of, with some unearthed massacres attributed to power struggles after the fall of the Roman Empire around 1,500 years ago (SN: 4/25/18). But a […]
