Scientists enlist lichens to monitor air pollution

An MIPT-based team of researchers has proposed analyzing lichen composition to assess atmospheric air quality when conventional monitoring stations are unavailable. They produced a case study of the Xanthoria parietina lichen, ...

'Super' enzyme protects against dangers of oxygen

(Phys.org)—Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells ...

Antioxidants are essential for bird embryo growth

(Phys.org) —As children we are told the importance of eating plenty of fruit and vegetables, but now scientists have confirmed that antioxidants found in these food groups are essential for the growth of bird embryos.

Toward a systems biology map of iron metabolism

Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a ...

Researchers use tiny diamonds to create intracellular sensors

Researchers have developed a new way to study the intricate dynamics within living cells by using optically trapped nanodiamond particles as intracellular sensors. Using custom built optical tweezers, the research team trapped ...

Technique enables adaptable 3-D printing

Three-dimensional printing technology makes it possible to rapidly manufacture objects by depositing layer upon layer of polymers in a precisely determined pattern. Once these objects are completed, the polymers that form ...

Artificial anti-oxidant may be the next go-to supplement

Naturally-derived anti-oxidants have become the 'it' health ingredient to look for in food. But researchers from UBC Okanagan and the University of Bologna have discovered that TEMPO—a well-known artificial anti-oxidant—is ...

A 'toolbox of biocatalysts' improves control over free radicals

One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals, may be familiar to you; these are the type of molecules we ...
