Histone H3-H4 tetramer found to be a copper reductase enzyme

A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried ...

Researchers develop blue-fluorescent molecular nanocapsules

Michito Yoshizawa, Zhiou Li, and collaborators at Tokyo Institute of Technology synthesized ~1 nanometer-sized molecular capsules with an isolated cavity using green and inexpensive zinc and copper ions. In sharp contrast ...

Graphene crystals grow better under copper cover

An approach that produces single-crystal graphene sheets on large-scale electrically insulating supports could help with the development of next-generation nanomaterial-based devices, such as very light and thin touchscreens, ...

Metals in taps and water pipes can dissolve into drinking water

Significant amounts of nickel, lead and copper can dissolve into the water from the water pipes and taps in buildings. This was revealed in the master's thesis of Meri Sipilä, who graduated recently from Aalto University. ...

Polluted land can be planted with flowers and tobacco

Zinnia (popular ornamental flowers) and tobacco adapt to copper in the soil. They accumulate heavy metal in the roots and limit the transport of copper to the aerial parts of the plant: stem, leaves, and beyond. At the same ...

Cheap metals can be used to make products from petroleum

The ancient alchemists sought to transform base metals, like lead, into precious gold. Now a new process developed at the University of Illinois at Chicago suggests that base metals may be worth more than their weight in ...
