Researchers push for better policies around toxic chemicals

From high levels of lead found in school drinking water to industry sites releasing toxic heavy metals into the air, over 40 years of regulations in the United States have failed to protect human and environmental health ...

Down to the microscopic level, nanoparticles show promising properties. A team of experts in Italy has spent years tailoring tiny inorganic materials and analysing their behaviour. Some have magnetic properties, others are ...

How a mitochondrial enzyme can trigger cell death

Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state ...

Surprising electronic disorder in a copper oxide-based ceramic

Cuprates, a class of copper-oxide ceramics that share a common building block of copper and oxygen atoms in a flat square lattice, have been studied for their ability to be superconducting at relatively high temperatures. ...

Very heavy elements deliver more electrons

Actinides, a series of 15 radioactive elements, are vital to medicine, energy, and national defense. Scientists examined two exceedingly rare actinides, berkelium and californium. These elements are at the extreme end of ...

Opening access to explore the synthetic chemistry of neptunium

Leftovers from nuclear reactors contain the element neptunium. To safely store the waste, scientists need to know more about how to control neptunium's chemistry. Knowing the stability of different oxidation states is central ...
