Working to create a new drought-resistant and water-saving wildflower, scientists at Texas Tech University's Department of Plant and Soil Science have introduced 'Raider Amethyst', a new cultivar of common prairie verbena.
Cynthia McKenney, Associate Professor of Horticulture at Texas Tech, says that Raider Amethyst was bred for homeowners and landscape architects who are interested in using more environmentally adapted materials in home gardens and public use areas. McKenney noted, "This project was to develop an improved wildflower release that would provide more compact, dependable color in a water-conserving landscape."
Raider Amethyst, or Glandularia bipinnatifida, is the second addition to the Raider Wildflower collection, following Melampodium leucanthum 'Raider White', commonly known as blackfoot daisy. It is recommended for use in low-maintenance plantings and water-conserving landscapes. It grows throughout the season with minimal care. Raider Amethyst is now available as commercial and experimental seed.
Of the new wildflower's impact, McKenney stated, "Urban water usage has been estimated to be about 70% of water consumption in the average metropolitan area. By utilizing water-conserving or drought-tolerant plants such as Raider Amethyst, people will be able to maintain an attractive landscape while reducing the use of potable water."

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
