RNA trafficking in parasitic plant systems

Certain parasitic plant species form symplastic connections to their hosts and thereby provide an additional system for studying RNA trafficking. The haustorial connections of Cuscuta and Phelipanche species are similar to graft junctions in that they are able to transmit mRNAs, viral RNAs, siRNAs, and proteins from the host plants to the parasite. In contrast to other graft systems, these parasites form connections with host species that span a wide phylogenetic range, such that a high degree of nucleotide sequence divergence may exist between host and parasites and allow confident identification of most host RNAs in the parasite system.

NSA/GCHQ: The HACIENDA Program for Internet Colonization

every device is a target for colonization, as each successfully exploited target is theoretically useful as a means to infiltrating another possible target. Port scanning and downloading banners to identify which software is operating on the target system is merely the first step of the attack (Figure 8). Top secret documents from the NSA seen by Heise demonstrate that the involved spy agencies follow the common methodology of online organized crime (Figure 9): reconnaissance (Figure 10) is followed by infection (Figure 11), command and control (Figure 12), and exfiltration (Figure 13). The NSA presentation makes it clear that the agency embraces the mindset of criminals. In the slides, they discuss techniques and then show screenshots of their own tools to support this criminal process (Figure 14, 15 and 16).

Fruits and Vegetables Are Trying to Kill You

Implicit in the research is a new indictment of the Western diet. Not only do highly refined foods present tremendous caloric excess, they lack these salutary signals from the plant world—“signals that challenge,” Mattson says. Those signals might otherwise condition our cells in a way that prevents disease. Another variant of the hormetic idea holds that our ability to receive signals from plants isn’t reactive and defensive but, in fact, proactive. We’re not protecting ourselves from biopesticides so much as sensing plants’ stress levels in our food. Harvard scientist David Sinclair and his colleague Konrad Howitz call this xenohormesis: benefitting from the stress of others.

Industry officials said that mainland China’s customs agency had notified companies that they were not allowed to ship to Japan any rare earth oxides, rare earth salts or pure rare earth metals, although the shipments are still allowed to go to Hong Kong, Singapore and other destinations. But no ban has been imposed on the export to Japan of semi-processed alloys that combine rare earths with other materials, the officials said. China has been trying to expand its alloy industry to create higher-paying jobs in mining areas, instead of exporting raw materials for initial processing.

Nightingale and Canary

Animations by Andy Thomas visualize birdsong samples into abstract sculptural forms - video embedded below:

Australian artist Andy Thomas specializes in creating ‘audio life forms’: beautiful abstract shapes that react to sounds. In this animated short, he visualizes two recorded bird sounds from the archives of the Netherlands Institute for Sound and Vision [] in Hilversum.
