What happens to magnetic nanoparticles in cells?

Although magnetic nanoparticles are being used more and more in cell imaging and tissue bioengineering, what happens to them within stem cells in the long term remained undocumented. Researchers from CNRS, the Sorbonne Université, ...

Why does Siberia get all the cool meteors?

In 1908 it was Tunguska event, a meteorite exploded in mid-air, flattening 770 square miles of forest. 39 years later in 1947, 70 tons of iron meteorites pummeled the Sikhote-Alin Mountains, leaving more than 30 craters. ...

Iron chemistry matters for ocean carbon uptake

For many years, scientists have speculated that seeding the ocean with iron might help to stave off climate change. Iron in seawater promotes the growth of phytoplankton, which in turn devours carbon dioxide from the atmosphere ...

Hydrogen from water in iron nanotruss structures

Swedish researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes ...

Greenland's summer ocean bloom likely fueled by iron

Iron particles catching a ride on glacial meltwater washed out to sea by drifting currents is likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study.

Study may help explain why iron can worsen malaria infection

Researchers at the National Institutes of Health have a possible explanation for why iron can sometimes worsen malaria infection. By studying mice and samples from malaria patients, the researchers found that extra iron interferes ...

Researchers discover new material to improve de-icing

Icy conditions can be deadly, whether you're flying into bad weather or too close to power transmission lines during a storm. Researchers at the University of Houston have reported the discovery of a material that can be ...
