A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
An international group of scientists, including botanists at the University of Oxford's Botanic Garden, has issued an urgent call for coordinated action to save the iconic genus, which contains the world's largest flowers. This follows a new study which found that most of the 42 species are severely threatened, yet just one of these is listed in the International Union for Conservation of Nature 's Red List of Threatened Species.
To better understand the vulnerability of these unique plants, a group of scientists established the first coordinated global network to assess the threats facingspecies are under threat: based on the criteria used by the IUCN, the scientists classified 25 as 'Critically Endangered', 15 as 'Endangered', and two as 'Vulnerable'.* Furthermore, over two-thirds are unprotected by regional or national conservation strategies.

Making contact: Researchers wire up individual graphene nanoribbonsResearchers have developed a method of 'wiring up' graphene nanoribbons (GNRs), a class of one-dimensional materials that are of interest in the scaling of microelectronic devices. Using a direct-write scanning tunneling microscopy (STM) based process, the nanometer-scale metal contacts were fabricated on individual GNRs and could control the electronic character of the GNRs. The researchers say that this is the first demonstration of making metal contacts to specific GNRs with certainty and that those contacts induce device functionality needed for transistor function.
