An unusual conifer found in a remote area of northern Vietnam has been identified as a genus and species previously unknown to science. The limestone ridges where the tree grows are among the most botanically rich areas in Vietnam, said Daniel Harder, currently director of the University of California at Santa Cruz (UCSC) Arboretum and a co-discoverer of the new species. The discovery is published in the current issue of the journal Novon.
"Biologists don’t need to contemplate finding life on another planet to imagine making extraordinary discoveries; the fact is, most of the species living on our own planet are still unknown," says Norman Platnick, program director in the National Science Foundation’s (NSF) division of environmental biology, which funded the research. "That kind of basic, new knowledge about life, its interrelationships, and how it is distributed across the globe, often has enormous practical implications, guiding the search for new medicines, new pesticides, and even new ways to control alien, invasive species."
Harder spent several years in Vietnam, working to establish an on-going survey of Vietnamese plants organized by the Missouri Botanical Garden, which received the NSF funding that helped enable this research. During that time, he and his collaborators discovered more than 100 new species of plants. But the conifer now known as the golden Vietnamese cypress is by far the most remarkable of those discoveries, he said.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
