The European X-ray Free-Electron Laser (EuXFEL) delivers extremely intense (>1012 photons pulse−1 and up to 27000 pulses s−1), ultrashort (<100 fs) and transversely coherent X-ray radiation, at a repetition rate of up to 4.5 MHz. Its unique X-ray beam parameters enable novel and groundbreaking experiments in ultrafast photochemistry and material sciences at the Femtosecond X-ray Experiments (FXE) scientific instrument. This paper provides an overview of the currently implemented experimental baseline instrumentation and its performance during the commissioning phase, and a preview of planned improvements. FXE's versatile instrumentation combines the simultaneous application of forward X-ray scattering and X-ray spectroscopy techniques with femtosecond time resolution. These methods will eventually permit exploitation of wide-angle X-ray scattering studies and X-ray emission spectroscopy, along with X-ray absorption spectroscopy, including resonant inelastic X-ray scattering and X-ray Raman scattering. A suite of ultrafast optical lasers throughout the UV–visible and near-IR ranges (extending up to mid-IR in the near future) with pulse length down to 15 fs, synchronized to the X-ray source, serve to initiate dynamic changes in the sample. Time-delayed hard X-ray pulses in the 5–20 keV range are used to probe the ensuing dynamic processes using the suite of X-ray probe tools. FXE is equipped with a primary monochromator, a primary and secondary single-shot spectrometer, and a timing tool to correct the residual timing jitter between laser and X-ray pulses.

PLEASE REDUCE TO 1-2 SENTENCES. The capability of X-ray diffraction for the microstructure investigations of metastable systems is illustrated on the example of thin films of titanium aluminium nitrides with high aluminium content, which are supersaturated and partially decomposed. In addition to the chemical composition, the surface mobility of the deposited species was employed as a factor influencing the microstructure of the thin films. It is shown how the micromechanical properties of the partially decomposed (Ti,Al)N thin films, which were deduced from the synchrotron diffraction experiments, are related to the thin film microstructure and to the decomposition mechanism. The prominent role of the crystallographic anisotropy of the macroscopic and microscopic lattice deformations in the understanding of the micromechanical properties is addressed.

The solvated centrosymmmtric title compound, [Li2(C24H34O4P)2(C10H8N2)2]·2C7H8, was formed in the reaction between {Li[(2,6-iPr2C6H3-O)2POO](MeOH)3}(MeOH) and 2,2'-bi­pyridine (bipy) in toluene. The structure has monoclinic (P21/n) symmetry at 120 K and the asymmetric unit consists of half a complex mol­ecule and one mol­ecule of toluene solvent. The diaryl phosphate ligand demonstrates a μ-κO:κO'-bridging coordination mode and the 2,2'-bi­pyridine ligand is chelating to the Li+ cation, generating a distorted tetra­hedral LiN2O2 coordination polyhedron. The complex exhibits a unique dimeric Li2O4P2 core. One isopropyl group is disordered over two orientations in a 0.621 (4):0.379 (4) ratio. In the crystal, weak C—H⋯O and C—H⋯π inter­actions help to consolidate the packing. Catalytic systems based on the title complex and on the closely related complex {Li[(2,6-iPr2C6H3-O)2POO](MeOH)3}(MeOH) display activity in the ring-opening polymerization of ∊-caprolactone and l-dilactide.

Reductive cyclization of 1,3,5-triphenyl- and 3-(2-meth­oxy­phen­yl)-1,5-di­phenyl­pentane-1,5-diones by zinc in acetic acid medium leads to the formation of 1,2,4-tri­phenyl­cyclo­pentane-1,2-diol [1,2,4-Ph3C5H5-1,2-(OH)2, C23H22O2, (I)] and 4-(2-meth­oxy­phen­yl)-1,2-di­phenyl­cyclo­pentane-1,2-diol [4-(2-MeOC6H4)-1,2-Ph2C5H5-1,2-(OH)2, C24H24O3, (II)]. Their single crystals have been obtained by crystallization from a THF/hexane solvent mixture. Diols (I) and (II) crystallize in ortho­rhom­bic (Pbca) and triclinic (Poverline{1}) space groups, respectively, at 150 K. Their asymmetric units comprise one [in the case of (I)] and three [in the case of (II)] crystallographically independent mol­ecules of the achiral (1R,2S,4r)-diol isomer. Each hydroxyl group is involved in one intra­molecular and one inter­molecular O—H⋯O hydrogen bond, forming one-dimensional chains. Compounds (I) and (II) have been used successfully as precatalyst activators for the ring-opening polymerization of ∊-caprolactone.

With the increasing trend of using microcrystals and intense microbeams at synchrotron X-ray beamlines, radiation damage becomes a more pressing problem. Theoretical calculations show that the photoelectrons that primarily cause damage can escape microcrystals. This effect would become more pronounced with decreasing crystal size as well as at higher energies. To prove this effect, data from cryocooled lysozyme crystals of dimensions 5 × 3 × 3 and 20 × 8 × 8 µm mounted on cryo-transmission electron microscopy (cryo-TEM) grids were collected at 13.5 and 20.1 keV using a PILATUS CdTe 2M detector, which has a similar quantum efficiency at both energies. Accurate absorbed doses were calculated through the direct measurement of individual crystal sizes using scanning electron microscopy after the experiment and characterization of the X-ray microbeam. The crystal lifetime was then quantified based on the D1/2 metric. In this first systematic study, a longer crystal lifetime for smaller crystals was observed and crystal lifetime increased at higher X-ray energies, supporting the theoretical predictions of photoelectron escape. The use of detector technologies specifically optimized for data collection at energies above 20 keV allows the theoretically predicted photoelectron escape to be quantified and exploited, guiding future beamline-design choices.

The National Zoo has been awarded a grant from the U.S. Fish and Wildlife Service to establish a captive population of the Virginia big-eared bat at the National Zoo’s Conservation & Research Center near Front Royal, Va. Only 15,000 Virginia big-eared bats remain living in caves in West Virginia, Virginia, Kentucky and North Carolina, and these are threatened by the white-nose syndrome.

Branched actin networks driven by Arp2/3 collaborate with actomyosin filaments in processes such as cell migration. The syncytial Drosophila blastoderm embryo also shows expansion of apical caps by Arp2/3 driven actin polymerization in interphase and buckling at contact edges by MyosinII to form furrows in metaphase. Here we study the role of Syndapin (Synd), an F-BAR domain containing protein in apical cap remodelling prior to furrow extension. synd depletion showed larger apical caps. STED super-resolution and TIRF microscopy showed long apical actin protrusions in caps in interphase and short protrusions in metaphase in control embryos. synd depletion led to sustained long protrusions even in metaphase. Loss of Arp2/3 function in synd mutants partly reverted defects in apical cap expansion and protrusion remodelling. MyosinII levels were decreased in synd mutants and MyosinII mutant embryos have been previously reported to have expanded caps. We propose that Syndapin function limits branching activity during cap expansion and affects MyosinII distribution in order to shift actin remodeling from apical cap expansion to favor lateral furrow extension.

What once were orchards and citrus groves now is a dense but sprawling urban area. The city of Los Angeles is considering ways to capture stormwater near where it falls so that water can be made use of throughout the city. ; Credit: Los Angeles Department of Water and Power

With a historic drought showing no signs of letting up, the city of Los Angeles is drafting a new plan to use more local water sources by capturing storm water throughout the L.A. basin. At recent community meetings, officials from the Department of Water and Power (along with the city's Sanitation Department) have been showcasing potential ideas for the final plan, due out this summer.

This new plan would make storm water about 4 percent of the city's annual water budget. For the first time, LA is talking about making storm water a small but reliable part of the city’s water sources – 25,000 acre-feet, or somewhat over 8 billion gallons of storm water a year. For perspective, a typical one-inch rain event in Los Angeles County produces more than 10 billion gallons of storm water, most of which hits asphalt and concrete, flows into storm drains and goes to the sea.

It’s hardly a new idea. But storm water capture has taken on additional urgency because of the drought, because of the increasing price of importing water, and because of local water quality rules.

On top of that, Los Angeles Mayor Eric Garcetti issued an executive order last October, directing the LADWP to cut its purchase of imported water in half within a decade, in part by cutting water consumption at least 20 percent.

Storm water capture projects have captured the energy and attention of environmental groups who’ve demonstrated them in backyards, neighborhoods, and alleyways.

LA could invest in much-larger-scale versions of those ideas. Good places for those bigger projects tend to be in the San Fernando Valley, where the geology is hospitable to rain water capture and the city has clearest rights. 

Some examples featured in the LADWP’s presentation aren’t yet approved, but are in consideration:

• Water capture and storage at the Van Norman Complex; 
• The Canterbury Power Line Easement, running between the Tujunga Spreading Grounds and the Pacoima Wash, which would capture 1500 acre-feet of water a year; and 
• Converting Strathern Park (near the Hollywood Freeway) from a disused gravel pit/landfill to a wetlands park, in joint operation with L.A. County. 

Storing storm water in the ground means protecting some areas from industrial pollution, and means filtering and treating polluted groundwater as it’s pulled from aquifers. Last November’s $7.5 billion dollar water bond earmarked funds for storm water capture and for groundwater cleanup. DWP officials say they’re hoping to bring some of that money to Los Angeles.

House Speaker Nancy Pelosi and Senate Majority Leader Mitch McConnell, in a rare joint statement on Saturday, declined an offer from the White House to make rapid COVID-19 tests available for Congress.

"Congress is grateful for the Administration's generous offer to deploy rapid COVID-19 testing capabilities to Capitol Hill, but we respectfully decline the offer at this time," Pelosi and McConnell said. "Our country's testing capacities are continuing to scale up nationwide and Congress wants to keep directing resources to the front-line facilities where they can do the most good the most quickly."

McConnell, R-Ky., plans to bring the Senate back into session on Monday, while Pelosi, D-Calif., and House Majority Leader Steny Hoyer, D-Md., said this week the House would not bring representatives back over coronavirus fears.

On Friday, Health and Human Services Secretary Alex Azar said on Twitter that the Trump administration would send three Abbott "point of care testing machines and 1,000 tests for their use" to Capitol Hill.

President Trump on Saturday tweeted: " No reason to turn it down, except politics. We have plenty of testing. Maybe you need a new Doctor over there. Crazy Nancy will use it as an excuse not to show up to work!"

Pelosi and Hoyer said they made the decision based on advice from the Capitol's attending physician, Brian Monahan. "The House physician's view was that there was a risk to members that was one he would not recommend taking," Hoyer said Tuesday.

So far, Rand Paul of Kentucky is the only senator to have tested positive for the coronavirus. In the House, seven members have tested positive or presumed to be positive for the coronavirus.

On Friday, McConnell shared guidelines from Monahan urging lawmakers and staff to maintain six feet of distance, limit the number of people in offices and to wear masks when possible.

Monahan has told Republican leaders that his office does not have the capacity to proactively test all 100 senators and can only test those who are ill, Politico reported.

A new study has investigated the effects of set-aside management —when fields are taken out of agricultural production — on common invertebrate decomposers in soil. The diversity of woodlice species was higher in set-aside fields compared to neighbouring wheat fields and this effect increased in older set-asides. This study highlights the importance of set-aside areas as habitats for soil invertebrates, which are important for soil health.
