New Database Catalogues Plants that Soak Up Contamination
Hyperaccumulators are unusual plants that can absorb much larger amounts of metal compounds in their leaves and stems than normal plants, and they are very useful for cleaning up contaminated land. As described in a New Phytologist article, researchers have published a database that provides easier access to information on the plant world’s hyperaccumulators.
The new Global Hyperaccumulator Database contains data on 721 species of hyperaccumulators. Investigators hope that it will expand as more discoveries are made.
The Global Hyperaccumulator Database can be found at http://hyperaccumulators.smi.uq.edu.au/collection/
“By virtue of their existence on metalliferous soils, hyperaccumulator plants are actively threatened by mining, and timely identification is necessary to take advantage of their unique properties,” said senior author Dr. Antony van der Ent, of The University of Queensland, in Australia.

Sex Determination Using Tooth EnamelNews
Researchers report a method for determining the sex of human remains using tooth enamel. A minimally destructive acid-etch procedure is utilised, followed by nanoflow liquid chromatography mass spectrometry. The method has potential for applications in bioarcheaology and medical-legal science.
Novel Lenses Enable X-ray Microscopy with Record ResolutionNews
Scientists have developed novel lenses that enable X-ray microscopy with record resolution in the nanometre regime. Using new materials, the research team has perfected the design of specialised X-ray optics and achieved a focus spot size with a diameter of less than ten nanometres.READ MORE
