Why are heavy metal hyperaccumulating plants so amazing?

Heavy metal hyperaccumulating plants: how and why do they do it? And what makes them so interesting?

The term "hyperaccumulator" describes a number of plants that belong to distantly related families, but share the ability to grow on metalliferous soils and to accumulate extraordinarily high amounts of heavy metals in the aerial organs, far in excess of the levels found in the majority of species, without suffering phytotoxic effects. Three basic hallmarks distinguish hyperaccumulators from re...

Phytoextraction of Heavy Metal by Hyperaccumulating and Non Hyperaccumulating Plants: Comparison of Cadmium Uptake and Storage Mechanisms in the Plants

Why Is the Liver So Amazing?

The liver is an organ that performs a lot of important functions in the body. However, if you observe it under the microscope, it seems to be very quiet because most of its cells remain in a non-dividing state (this is called quiescent). The liver is so important that it is provided with a great ability to tolerate several kinds of injuries. After a wound or other damage, all the cells in the l...

Why are clicks so exclusive ?

Clicks occur abundantly in the languages of southern Africa, but are not found anywhere else. This is unexpected since the clicks seem to be both auditorily salient and easy to produce. This paper suggests that the reason for the areal skewness of clicks lies in the African phonetictypological environment rather than in production or perception constraints. In particular, clicks are limited to ...

Leaching of heavy metal from native plants by chemical leachants

Plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. This study provides an evaluation of extractants for the removal of lead from Abutilon Theophrastus biomass. The research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...
