Calibration of area detectors from powder diffraction standards is widely used at synchrotron beamlines. From a single diffraction image, it is not possible to determine both the sample-to-detector distance and the wavelength, but, with images taken from multiple positions along the beam direction and where the relative displacement is known, the sample-to-detector distance and wavelength can both be determined with good precision. An example calibration using the GSAS-II software package is presented.

The title compound (systematic name: bis­{2-[4-(acet­yloxy)-1H-indol-3-yl]ethan-1-aminium} but-2-enedioate), 2C14H19N2O2+·C4H2O42−, has a single protonated psilacetin cation and one half of a fumarate dianion in the asymmetric unit. There are N—H⋯O hydrogen bonds between the ammonium H atoms and the fumarate O atoms, as well as N—H⋯O hydrogen bonds between the indole H atoms and the fumarate O atoms. The hydrogen bonds hold the ions together in infinite one-dimensional chains along [111].

Molecular replacement (MR) is the predominant route to solution of the phase problem in macromolecular crystallography. Where the lack of a suitable homologue precludes conventional MR, one option is to predict the target structure using bioinformatics. Such modelling, in the absence of homologous templates, is called ab initio or de novo modelling. Recently, the accuracy of such models has improved significantly as a result of the availability, in many cases, of residue-contact predictions derived from evolutionary covariance analysis. Covariance-assisted ab initio models representing structurally uncharacterized Pfam families are now available on a large scale in databases, potentially representing a valuable and easily accessible supplement to the PDB as a source of search models. Here, the unconventional MR pipeline AMPLE is employed to explore the value of structure predictions in the GREMLIN and PconsFam databases. It was tested whether these deposited predictions, processed in various ways, could solve the structures of PDB entries that were subsequently deposited. The results were encouraging: nine of 27 GREMLIN cases were solved, covering target lengths of 109–355 residues and a resolution range of 1.4–2.9 Å, and with target–model shared sequence identity as low as 20%. The cluster-and-truncate approach in AMPLE proved to be essential for most successes. For the overall lower quality structure predictions in the PconsFam database, remodelling with Rosetta within the AMPLE pipeline proved to be the best approach, generating ensemble search models from single-structure deposits. Finally, it is shown that the AMPLE-obtained search models deriving from GREMLIN deposits are of sufficiently high quality to be selected by the sequence-independent MR pipeline SIMBAD. Overall, the results help to point the way towards the optimal use of the expanding databases of ab initio structure predictions.

Although the success of molecular-replacement techniques requires the solution of a six-dimensional problem, this is often subdivided into two three-dimensional problems. REMO09 is one of the programs which have adopted this approach. It has been revisited in the light of a new probabilistic approach which is able to directly derive conditional distribution functions without passing through a previous calculation of the joint probability distributions. The conditional distributions take into account various types of prior information: in the rotation step the prior information may concern a non-oriented model molecule alone or together with one or more located model molecules. The formulae thus obtained are used to derive figures of merit for recognizing the correct orientation in the rotation step and the correct location in the translation step. The phases obtained by this new version of REMO09 are used as a starting point for a pipeline which in its first step extends and refines the molecular-replacement phases, and in its second step creates the final electron-density map which is automatically interpreted by CAB, an automatic model-building program for proteins and DNA/RNA structures.

Good prior estimates of the effective root-mean-square deviation (r.m.s.d.) between the atomic coordinates of the model and the target optimize the signal in molecular replacement, thereby increasing the success rate in difficult cases. Previous studies using protein structures solved by X-ray crystallography as models showed that optimal error estimates (refined after structure solution) were correlated with the sequence identity between the model and target, and with the number of residues in the model. Here, this work has been extended to find additional correlations between parameters of the model and the target and hence improved prior estimates of the coordinate error. Using a graph database, a curated set of 6030 molecular-replacement calculations using models that had been solved by X-ray crystallography was analysed to consider about 120 model and target parameters. Improved estimates were achieved by replacing the sequence identity with the Gonnet score for sequence similarity, as well as by considering the resolution of the target structure and the MolProbity score of the model. This approach was extended by analysing 12 610 additional molecular-replacement calculations where the model was determined by NMR. The median r.m.s.d. between pairs of models in an ensemble was found to be correlated with the estimated r.m.s.d. to the target. For models solved by NMR, the overall coordinate error estimates were larger than for structures determined by X-ray crystallography, and were more highly correlated with the number of residues.

Many biologists are now routinely seeking to determine the three-dimensional structures of their proteins of choice, illustrating the importance of this knowledge, but also of the simplification and streamlining of structure-determination processes. Despite the fact that most software packages offer simple pipelines, for the non-expert navigating the outputs and understanding the key aspects can be daunting. Here, the structure determination of the type IV pili (TFP) protein PilA1 from Clostridioides difficile is used to illustrate the different steps involved, the key decision criteria and important considerations when using the most common pipelines and software. Molecular-replacement pipelines within CCP4i2 are presented to illustrate the more commonly used processes. Previous knowledge of the biology and structure of TFP pilins, particularly the presence of a long, N-terminal α-helix required for pilus formation, allowed informed decisions to be made during the structure-determination strategy. The PilA1 structure was finally successfully determined using ARCIMBOLDO and the ab initio MR strategy used is described.

The performance of automated protein model building usually decreases with resolution, mainly owing to the lower information content of the experimental data. This calls for a more elaborate use of the available structural information about macromolecules. Here, a new method is presented that uses structural homologues to improve the quality of protein models automatically constructed using ARP/wARP. The method uses local structural similarity between deposited models and the model being built, and results in longer main-chain fragments that in turn can be more reliably docked to the protein sequence. The application of the homology-based model extension method to the example of a CFA synthase at 2.7 Å resolution resulted in a more complete model with almost all of the residues correctly built and docked to the sequence. The method was also evaluated on 1493 molecular-replacement solutions at a resolution of 4.0 Å and better that were submitted to the ARP/wARP web service for model building. A significant improvement in the completeness and sequence coverage of the built models has been observed.

Fragment-based molecular replacement exploits the use of very accurate yet incomplete search models. In the case of the ARCIMBOLDO programs, consistent phase sets produced from the placement and refinement of fragments with Phaser can be combined in order to increase their signal before proceeding to the step of density modification and autotracing with SHELXE. The program ALIXE compares multiple phase sets, evaluating mean phase differences to determine their common origin, and subsequently produces sets of combined phases that group consistent solutions. In this work, its use on different scenarios of very partial molecular-replacement solutions and its performance after the development of a much-optimized set of algorithms are described. The program is available both standalone and integrated within the ARCIMBOLDO programs. ALIXE has been analysed to identify its rate-limiting steps while exploring the best parameterization to improve its performance and make this software efficient enough to work on modest hardware. The algorithm has been parallelized and redesigned to meet the typical landscape of solutions. Analysis of pairwise correlation between the phase sets has also been explored to test whether this would provide additional insight. ALIXE can be used to exhaustively analyse all partial solutions produced or to complement those already selected for expansion, and also to reduce the number of redundant solutions, which is particularly relevant to the case of coiled coils, or to combine partial solutions from different programs. In each case parallelization and optimization to provide speedup makes its use amenable to typical hardware found in crystallography. ARCIMBOLDO_BORGES and ARCIMBOLDO_SHREDDER now call on ALIXE by default.

Model quality assessment programs estimate the quality of protein models and can be used to estimate local error in protein models. ProQ3D is the most recent and most accurate version of our software. Here, it is demonstrated that it is possible to use local error estimates to substantially increase the quality of the models for molecular replacement (MR). Adjusting the B factors using ProQ3D improved the log-likelihood gain (LLG) score by over 50% on average, resulting in significantly more successful models in MR compared with not using error estimates. On a data set of 431 homology models to address difficult MR targets, models with error estimates from ProQ3D received an LLG of >50 for almost half of the models 209/431 (48.5%), compared with 175/431 (40.6%) for the previous version, ProQ2, and only 74/431 (17.2%) for models with no error estimates, clearly demonstrating the added value of using error estimates to enable MR for more targets. ProQ3D is available from http://proq3.bioinfo.se/ both as a server and as a standalone download.

Host Jon Stewart announced at Tuesday's "The Daily Show" taping that he is leaving the show.

Comedy Central confirmed the news in a statement, saying that Stewart will be leaving later this year:

"For the better part of the last two decades, we have had the incredible honor and privilege of working with Jon Stewart. His comedic brilliance is second to none. Jon has been at the heart of Comedy Central, championing and nurturing the best talent in the industry, in front of and behind the camera. Through his unique voice and vision, ‘The Daily Show’ has become a cultural touchstone for millions of fans and an unparalleled platform for political comedy that will endure for years to come. Jon will remain at the helm of ‘The Daily Show’ until later this year. He is a comic genius, generous with his time and talent, and will always be a part of the Comedy Central family."

The news comes less than two months after Stephen Colbert brought "The Colbert Report" to an end in order to prepare for hosting CBS's "Late Show," replacing David Letterman after he leaves later this year.

"The Daily Show" existed before Jon Stewart, hosted from 1996 until 1998 by Craig Kilborn, but Stewart took the show into a bolder political direction and made it a cultural landmark, becoming the go-to news source for numerous young people. Polls started to show Jon Stewart as being one of the most trusted newsmen in America.

It's just over three weeks after Comedy Central launched "The Nightly Show" with Larry Wilmore and details have yet to be announced about the future of Comedy Central's late night lineup.

The show has created hosts for other networks, with Colbert leaving for CBS after getting his start as a "Daily Show" correspondent and John Oliver, who served as a fill-in host while Stewart shot the film "Rosewater," left for his own weekly rundown of the news "Last Week Tonight" at HBO. The show's starmaking power also includes actors such as Steve Carell, Ed Helms and more, and new "Saturday Night Live" Weekend Update anchor Michael Che.

Stewart didn't announce his plans for what comes next. He directed the 2014 film "Rosewater," based on journalist Maziar Bahari's memoir detailing his imprisonment in Iran following an interview with "The Daily Show's" Jason Jones.

Stewart previously talked about "Rosewater" with KPCC's "The Frame," saying at the time that "The Daily Show" isn't all fun.

"As sad as it sounds, people might say, 'Man, working at 'The Daily Show,' that's gotta be a blast. You just sit around and laugh all day,'" Stewart said. "And you're like, 'No, we have a meeting at 9, and the 9 meeting has to be over by 9:30, and the scripts have to be in by 11, because if they're not, then we miss this deadline.'"

He also told the Hollywood Reporter last summer that he didn't know how much longer he would stay with the show.

"I mean, like anything else, you do it long enough, you will take it for granted, or there will be aspects of it that are grinding. I can't say that following the news cycle as closely as we do and trying to convert that into something either joyful or important to us doesn't have its fraught moments," Stewart said.

The show, one of Comedy Central's top franchises, will likely continue. John Oliver and Stephen Colbert would have seemed like the heirs apparent before they left; of the current staff, Samantha Bee, Jason Jones and Aaasif Mandvi are the longest-running correspondents, with Bee starting all the way back in 2003. Jones filled in for Stewart as anchor last fall, assisted by his wife Samantha Bee, when Stewart was out sick.

The show has also pushed for expanded diversity in its own cast, along with launching "The Nightly Show" with a black host and a minority panel, so that could point to a more diverse host in the future. The show has also recently expanded its international perspective, with Trevor Noah covering international news, Hasan Minhaj as the new Indian correspondent and Egyptian satirist Bassem Youssef joining as a Middle East correspondent.

Correction: An earlier version of this story referred to "Rosewater" as a documentary; it is a drama, based on Maziar Bahari's memoir. KPCC regrets the error.

A quick update since FansUnite Entertainment Inc. (FANS:CSE) went live on Tuesday, May 5, because big things are happening in the industry, thus showing there is an enormous appetite for this kind of technology especially now, as we (very slowly) emerge out of this COVID pandemic.

On the sports front, Germany announced that its Bundesliga soccer will resume games in May, yet with tight restrictions and no fans. This is followed by the Turkish soccer league, which plans to resume playing on June 12. The Ultimate Fighting Championship (UFC), with a huge draw to the masses—the UFC 246 prelims averaged 1.767 million viewers on ESPN—will return at VyStar Veterans Memorial Arena in Jacksonville, Fla., on May 9, again featuring no live fans. So as more sports emerge in our "new reality," where will those fans be? Online, of course! In a fanless sports environment we're going to see a lot of online engagement no matter what sport or activity that may be. That's going to spawn even more online attention, which will likely hold firm even after we emerge from our home quarantine.

The industry is rapidly consolidating. On Tuesday we alluded to The Stars Group Inc. (formerly Amaya), which, according to Bloomberg, "saw record revenue in its first quarter as COVID-19 led to an increase in online activity starting in March. Indeed TSGI.T has had a great run from $18 mid-March to a high of $40 on May 1 after it confirmed shareholder approval of a friendly takeover by UK based Flutter Entertainment plc. (LSE:FLTR.L - News). The two create a £10 billion (US$12 billion) giant, according to Racing Post, and combine for more than 13 million customers, US$4.6 billion in revenue and US$1.7 billion in EBITDA.

Investors are getting on board

In our previous note we referred to DraftKings (NASDAQ:DKNG), which launched as recently as April 23, in the thick of this stay-at-home pandemic. After completing a merger with Diamond Eagle, a special purpose acquisition company, and back-end technology provider SBTech, its stock soared. DraftKings' stock jumped 14% in its first day of trading before closing up 10.38% at $19.35. The company was also able to add another half a billion dollars on the balance sheet at a time when it's not easy to raise money. That company currently has a $17 billion market capitalization.

Meanwhile there's been a noticeable correlation of trading activity in the industry from mid-March to the end of April:

• Prior to the merger with Canadian The Stars Group, Dublin, Ireland-based Flutter, trading as OTC:PDYPY in the U.S., had a good run of its own. Since mid-March it doubled from $31 to $64 by the end of April, despite any global sport-killing pandemic.

• UK-based GVC Holdings PLC (LSE:GVC) gained 23% in the last month, from $611 to $750, reaching a US$4.3 billion market capitalization.

• After falling from February highs of $30, Scientific Games (NASDAQ:SGMS) more than tripled from a $4 low mid-march to $13 by the end of April to again reach a $1 billion market valuation.

• Penn National Gaming (NASDAQ:PENN), now at a US$1.8 billion market capitalization, has a chart that mirrors SGMS. After February highs of $38, PENN rebounded through the COVID crisis. It also more than tripled from a low of $4.50 mid-March to a $17.80 high by the end of April.

• Score Media and Gaming (SCR.V,) with a market capitalization of $185 million, during that same period, ran from $0.32 to $0.42 mid-march to April 29, gaining 31%

• (are you starting to a pattern here?)

On the regulatory front, Colorado, became the next state to legalize sports bargaining following New Jersey, Nevada, Delaware and Pennsylvania. The state is poised to generate $6 billion in annual wagers and an estimated $400 million in revenue once the industry matures, according to Dustin Gouker, chief analyst for PlayColorado.com. According to the Denver Post, Colorado fans will have their pick of 17 digital sportsbooks currently licensed to operate in the state.

FansUnite Is at a Small-Cap Entry Point with Tremendous Upside.

It is in this environment that FansUnite launched on the Canadian Securities Exchange on May 5. "We are just getting started," said CEO Darius Eghdami. "We've bought a great asset in McBookie and will be continuing to focus on M&A." McBookie, the company's first acquisition, is a white-label sportsbook in the UK, focusing on the Scottish market. It offers 200,000 members active in sports and virtual games, and boasts over $100 million turnover cumulatively the last three years. "We want to be active in finding that next 'McBookie' operating in a niche market, looking at Esports assets and also creative ways to get into the U.S. market. "

After a financing at $0.35, the now-trading company rests slightly above that as a relatively new and unknown entity—so far—which is why now is great opportunity participate in a smaller scale, yet leveraged, consolidation play. "We have a great opportunity to use our stock as currency, and then grow and scale companies through our team and resources," says Eghdami.

"We also have great investors and support, a very experienced board and management team and a clear vision of how we want to be that next gaming giant. The path has been shown by other Canadian gaming companies such as Amaya, and we want to follow that path and execute on our vision."

It's an ambitious plan: a CA$25 million market-cap company, $2 million in the bank, with a consolidation plan to attack a $1 trillion online industry. Yet FansUnite comes out of the gate with strong financial backing led by board member Shafin Diamond, CEO of Victory Square since 2015, a venture builder that builds start-ups in web, mobile, gaming, AI and AR/VR. Diamond has launched 40 start-ups in 24 countries, employed more than 350 people, and has generated over $100 million in annual revenues.

Eghdami says the immediate plan is to strengthen its UK presence with McBookie and focus on M&A activity, while continuing to develop its software platform.

The games are just beginning.

President Trump speaks at the White House Friday. He is replacing an official who issued a report that found testing delays and equipment shortages at hospitals.; Credit: Jim Watson/AFP via Getty Images

President Trump is moving to replace the Department of Health and Human Services watchdog whose office found severe shortages of medical supplies in hospitals as COVID-19 cases surged.

In a Friday night announcement, the White House named Jason Weida as its nominee to take the permanent inspector general post currently occupied by Christi Grimm, who's been in that role in an acting capacity since January.

A longtime staffer with Health and Human Services, Grimm was leading the inspector general's office in April when it issued a report chronicling testing delays — up to seven days in some cases — as well as severe shortages of supplies in hospitals amid the COVID-19 pandemic.

"Hospitals reported that they were unable to keep up with COVID-19 testing demands because they lacked complete kits and/or the individual components and supplies needed to complete tests," the survey of 323 hospitals found. "When patient stays were extended while awaiting test results, this strained bed availability, personal protective equipment (PPE) supplies, and staffing."

The report also recalled how one hospital had even resorted to making its own disinfectant.

Trump reacted to the report by calling its findings "wrong," asking to know the name of the inspector general and suggesting the report was politically motivated. He later took to Twitter to castigate Grimm and the report even further.

"Why didn't the I.G., who spent 8 years with the Obama Administration (Did she Report on the failed H1N1 Swine Flu debacle where 17,000 people died?), want to talk to the Admirals, Generals, V.P. & others in charge, before doing her report. Another Fake Dossier!" Trump tweeted in early April.

Grimm is a career official, not a political appointee, and began serving in the Office of the Inspector General in 1999.

The nomination of Weida — currently an assistant U.S. attorney — marks the latest replacement of a high-level watchdog by the president. A month ago, he fired the inspector general who raised concerns that eventually led to his impeachment. Days later, he removed the inspector general charged with overseeing the government's coronavirus response bill.

Sen. Patty Murray, ranking Democrat on the Health, Education, Labor and Pensions Committee, said that Trump's nominee "must not get through the Senate without ironclad commitments" to continue the agency's current investigations without political interference.

"We all know the President hasn't told people the truth about this virus or his Administration's response, and late last night, he moved to silence an independent government official who did," Murray said in a statement released on Saturday. "Anyone who demands less will be complicit in the President's clear pattern of retaliation against those who tell the truth."

Health and Human Services did not comment to NPR on Grimm's future role, but said in statement that the agency had been preparing "to assist a new Inspector General appointee over a year ago, when the previous presidentially-appointed and senate-confirmed Inspector General first announced his intention to retire from government service. We will continue to work conscientiously to support a smooth leadership transition."

Walter Flores was unemployed for 8 months in 2014 but is now working in sales for Workforce Solutions in Compton; Credit: Brian Watt/KPCC

California's unemployment rate continued its decline in December, ending the year at 7 percent, according to figures released Friday by the state Employment Development Department.

But in Compton, Willowbrook and the Florence-Graham section of Los Angeles County, it remains about double that, data show.

“You might have work this week. But next week, you won’t have work,” said James Hicks, 36, 0f Compton. He's worked in warehouses through staffing agencies, but said the jobs have always been temporary.

Statewide, California has added jobs at a faster rate than the United States for three straight years, according to Robert Kleinhenz, Chief Economist with the Los Angeles County Economic Development Corporation. He pointed out the statewide unemployment rate is now where it was June 2008. 

"All in all, with the recession now five years back in our rearview mirror, we’re finally at the point where we can say that we have shrugged off quite a bit of the pain that occurred back during those times," Kleinhenz said.

The Los Angeles County metro area saw a net gain of almost 71,000 jobs in 2014.  The County's overall unemployment rate has fallen to 7.9 percent from 9.2 percent a year ago.

But Compton's unemployment rate was 13 percent in December.

“I’d rather have a  full-time type of gig, working 40 hours a week, but right now, even if you get 25 hours, it’s a blessing,” said Hicks, the warehouse worker in Compton.

On Thursday, he interviewed to be a guard with a security firm, but was told there weren’t any positions available. He had another security guard job six months ago that he thought might become full time and permanent. 

"It was going all right for about two to three months, until they cut my hours and days," Hicks said. 

Walter Flores lives in La Mirada but currently works as an account executive in the Compton office of Workforce Solutions. He was unemployed for about eight months last year after a car accident.

"Losing what you love to do is a tough one, but I'm back," he said. "2015 is going to be a great year."

Flores said most major warehouse and logistics companies prefer to hire temporary workers through industrial staffing firms like the one where he's working because their needs are sporadic.  

But he said it's still a potential opportunity.

"It doesn't matter that it's a temporary position, as long as you put your foot in the door, and then you let the employer know how much value you are for the company," Flores said.  

Hicks, who's earned a GED, wants to find a program to study physical therapy. But first, he’d like to find a job. 

He said you can't judge Compton’s residents by its unemployment rate.

"Some of us out here who [are] looking for jobs, but sometimes it’s the luck of the draw," he said. "It’s kind of scarce out there.”

Noise caused by construction of Germany’s first offshore wind farm caused significant habitat disturbance for harbour porpoises, according to a recent study. Its results suggest that porpoises avoided areas up to 20 kilometres from the noise source during construction of the wind farm’s foundations.

Benefits gained from the use of logging residues as a fuel depend more on the type of fossil fuel they replace than on the distance the residues have to travel, according to new research. Residues that replace coal produce the greatest reductions in CO2 emissions.

Progress towards achieving a sustainable urban environment may be measured by sustainability indicators (SIs), which can be chosen to represent values that are important to local communities. A recent study has assessed a set of SIs developed by both sustainability experts and local citizens and suggests that local communities can attach different values to SIs to reflect local values and understandings of sustainability.

Industry has traditionally claimed that strict environmental regulation has a negative effect on its competitiveness. However, a recent theory proposes it may actually increase productivity and innovation. This study used a large database of inter-sectoral transactions to investigate the effect of environmental taxation on manufacturing businesses across Europe. The findings show that environmental regulation can increase innovation and productivity.

In a breakthrough, researchers have demonstrated a new model that shows how competing pieces of information spread in online social networks and the Internet of Things (IoT).
