The cationic complex in the title compound, [Ir(C9H7N2)2(C12H8N2)]PF6, comprises two phenylpyrazole (ppz) cyclometallating ligands and one 1,10-phenanthroline (phen) ancillary ligand. The asymmetric unit consists of one [Ir(ppz)2(phen)]+ cation and one [PF6]− counter-ion. The central IrIII ion is six-coordinated by two N atoms and two C atoms from the two ppz ligands as well as by two N atoms from the phen ligand within a distorted octahedral C2N4 coordination set. In the crystal structure, the [Ir(ppz)2(phen)]+ cations and PF6− counter-ions are connected with each other through weak intermolecular C—H...F hydrogen bonds. Additional C—H...π interactions between the rings of neighbouring cations consolidate the three-dimensional network. Electron density associated with additional disordered solvent molecules inside cavities of the structure was removed with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s). The title compound has a different space-group symmetry (C2/c) from its solvatomorph (P21/c) comprising 1.5CH2Cl2 solvent molecules per ion pair.

The enanti­opure monopyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-but­oxy-1-cyano-2-oxo­ethyl­idene)pyrrolidine-2-carboxyl­ate, C13H18N2O4, (1), represents a potential ligand and an attractive inter­mediate for the synthesis of chiral metal com­plexes. At the mol­ecular level, the com­pound features an intra­molecular N—H⋯O hydrogen bond; neighbouring mol­ecules inter­act via N—H⋯N contacts to form chains along [100]. Due to its elemental com­position, resonant scattering of the target com­pound is entirely insignificant for diffraction experiments with Mo Kα and small even for Cu Kα radiation. A preliminary study with the harder radiation type confirmed the chiral space group and the suitability of the single crystal chosen; as expected, the results concerning the absolute structure remained com­pletely inconclusive. A second data collection with the longer wavelength gave satisfactory quality indicators for the correct handedness of the mol­ecule, albeit with high standard uncertainties. The absolute configuration has been assessed independently: CD spectra for both enanti­omers of the target mol­ecule were calculated and the spectrum for the S-configured stereoisomer was in agreement with the experiment. The Cotton effect of (1) may be ascribed to π–π* transitions from HOMO to LUMO and from HOMO to LUMO+1. As both independent techniques agree with respect to the handedness of the target mol­ecule, the absolute structure may be assigned with a high degree of confidence.

The title com­pound, tetra­ethyl­ammonium tetra­thio­rhenate, [(C2H5)4N][ReS4], has, at room temperature, a disordered structure in the space group P63mc (Z = 2, α-phase). A phase transition to the monoclinic space group P21 (Z = 2, γ-phase) at 285 K leads to a pseudo-merohedral twin. The high deviation from the hexa­gonal metric causes split reflections. However, the different orientations could not be separated, but were integrated using a large integration box. Rapid cooling to 110–170 K produces a metastable β-phase (P63, Z = 18) in addition to the γ-phase. All crystals of the β-phase are contaminated with the γ-phase. Additionally, the crystals of the β-phase are merohedrally twinned. In contrast to the α-phase, the β- and γ-phases do not show disorder.

The Academy Awards have made history with breakthroughs for minorities in the past — but with this year's nominations, observers are noting how white the Oscars are, with no actors of color nominated in any of this year's acting categories.

It marks the least diverse nominations since 1998. People have been speaking out about this disconnect, with films like "Selma" being shut out of the acting nominations (though it did pick up a Best Picture nomination).

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 still from "POWER/RANGERS," a highly-produced Power Rangers fan film starring James Van Der Beek and Katee Sackhoff.

Update 2/28: The "POWER/RANGERS" film is back on YouTube and Vimeo. Watch the censored YouTube version with a new viewer discretion disclaimer here:

POWER/RANGERS

You can also watch the Vimeo version, featuring more adult content. The video's description emphasizes its lack of connection in any official way to the Power Rangers:

"Deboot of the Power Rangers. My take on the FAN FILM. Not a pilot, not a series, not for profit, strictly for exhibition. This is a bootleg experiment not affiliated or endorsed by Saban Entertainment or Lionsgate nor is it selling any product. I claim no rights to any of the characters (don't send me any money, not kickstarted, this film is free). This is the NSFW version. An alternate safe version is on youtube."

Director Joseph Kahn tells Deadline, "They put these disclaimers on so kids so don’t confuse our super-violent film with their Power Rangers brand. There are no hard feelings. We signed contracts. We can play it anywhere we want on all platforms. I think they realized that people just want to see it."

Previously: A Power Rangers short film went viral this week, starring Katee Sackhoff (Battlestar Galactica) and James Van Der Beek (Dawson!) in a Tarantino-meets-sci-fi take on a dark future for the formerly Mighty Morphin'.

The company behind the 22-year history of the kids/toy icons issued takedown requests, leading to it being pulled from Vimeo and, on Thursday afternoon, a toned-down version being taken off YouTube. At the time, the video had received over 10 million views. It's still available to watch in this Facebook embed from the producer's Facebook page:

The film was directed by Joseph Kahn, best known as the music video director behind clips like Taylor Swift's "Blank Space" as well as videos for Britney Spears, U2 and others, and produced by Adi Shankar, who was also behind "The Grey" and "Dredd." Kahn co-wrote the film with Van Der Beek and lesser-known writer Dutch Southern.

This isn't the first quasi-legal fan film produced by Shankar. He's also done the same with Marvel Comics characters the Punisher and Venom. The Punisher film even had one of the actors who played the character on screen, Thomas Jane.

Watch those films (Warning: Adult language and violence):

Punisher short

Venom short

Kahn tells HitFix that Shankar came to him, offering him the chance to reboot an existing property.

One reason for the current legal contentiousness: The Power Rangers are set to hit the big screen next year in a Lionsgate film. Kahn says that, if that film was offered to him, he wouldn't be interested.

"I wouldn't even want to make 'Power Rangers: The Movie' for real," Kahn told HitFix. "Like if I had to make a 'Power Rangers' movie, this is it. It's 14 minutes long, and it's violent, and this is what I have in me. If they offered me the $200 million version, the PG-13 version, I literally wouldn't do it."

There's been a strong response to the video, but the response has been mixed — among the original Power Rangers. The original Green Ranger, actor Jason David Frank, said on Facebook that he was approached to be in the movie but declined. (The film's director denies this claim, saying that Frank must have confused them with another project.) Frank also criticized the adult content.

"I'm just a PG-13 guy," Frank said. "The cuss words, the drugs, all this other stuff, it doesn't fly with me." He says that he thinks the Power Rangers are still connected with kids, and he didn't like the idea of doing a dark and gritty version in that context. (Watch his video below.)

Green Ranger video

But the original Pink Ranger, actress Amy Jo Johnson, gave the film her stamp of approval, which Sackhoff enthusiastically responded to.

Katee Sackhoff tweet

Sackhoff told the Nerdcore Movement site that she loves fan films.

"Doing a fan video is kind of the biggest honor you can give a franchise. It’s something that inspired you so much that you want to create," Sackhoff said.

Kahn defended "POWER/RANGERS" on Twitter as being protected due to it being a satire and also cited fair use laws and free speech. He argued that there are lots of other fan films and pointed out that YouTube showed more leniency, leaving it up.

"Every image in POWER/RANGERS is original footage," Kahn wrote in a series of tweets to Vimeo. "Nothing was pre-existing. There is no copyrighted footage in the short."

He also said that it's being given away for free and that Kahn paid for it himself.

Kahn tweet

"It is just as if I drew a pic of Power Rangers on a napkin and I gave it to my friend," Kahn wrote. "Is it illegal to give pic I drew of a character on a napkin to someone for free? No. The world is watching your actions right now."

In a touch of irony, the video had been selected as a Vimeo staff pick before the service took it down. They also responded to complaints about it being taken down, saying that they had to due to the Digital Millennium Copyright Act, and that they would restore the video immediately if the copyright claim was withdrawn, telling fans to complain to Power Rangers copyright holder Saban.

YouTube tweet

Despite the short film's success, hardcore Power Rangers fans are less sure about it, Shamus Kelley tells KPCC. Kelley created his own Rangers fan series, as well as co-hosting a Power Rangers podcast with over 300 episodes so far.

Casual fans are "far more open to the idea of dark/gritty because they see it as the show growing up with them," Kelley says. To hardcore fans, "it was either an abomination or the greatest unintended parody ever."

Kahn tells HitFix that the parody, of both Power Rangers and fan films in general, is definitely intended.

"The dark and gritty reboot thing is such a cliché that the intention was not only to make it dark and gritty but make it even darker and grittier than you could possibly imagine, hence the brains, the blood and the violence and the sex," Kahn said.

Kahn is set to answer questions about the film in a Reddit AMA on Friday at 2 p.m. We'll have to wait and see if there will be anywhere to watch it at the time.

Do you want to track the Dodgers as the new season gets underway, but either don't have cable or are at work during the game? Maybe you want to keep an eye on the boys in blue but have an office job that gives you checks in black and white, and you want to keep your bleeding red for your favorite team from sending your bank account into the red as well. Or maybe you just aren’t going to have access to a TV at the time. Here are four ways to check the Dodgers out this season.

1. Track what’s happening with MLB.com’s free Gameday service

Want to see what’s going on as if the Dodgers game was a video game? You have to pay if you want to watch video (with alternate angles!) or listen to audio with Major League Baseball's MLB.tv service — but you can watch virtual avatars simulating the game with MLB Gameday for free. Just visit MLB.com/scores, then click on the Gameday button beneath the game you want to follow. Or, you can keep it more old school by tracking scores on the scores page — alongside video highlights.

2. Follow what’s going on on Twitter

Want to keep an eye on things but don’t want to stare at a streaming video feed? You can follow what’s happening with Twitter. The Dodgers themselves tweet highlights and results at @Dodgers, plus you can do a search for “Dodgers” or track what’s happening on various popular hashtags, including #Dodgers, #ThinkBlue and #ITFDB (It’s Time For Dodgers Baseball).

3. Listen to the radio, over the air or online

The official Dodgers radio broadcaster in L.A. is AM 570 L.A. Sports. As noted above, you can also pay to listen to audio from MLB.tv — but the service isn't available for local, "in-market" games, which are blacked out as part of their contracts with local broadcasters. The Dodgers broadcasts are also available in Spanish on 1020 AM KTNQ.

4. Stream ESPN on your computer, phone or tablet

ESPN lets you watch the opening day game and others throughout the season online... well, some of you, at least. Due to various cable company deals and other red tape, you have to already be a cable subscriber — sorry, cord cutters — but most major cable company subscribers can log in and stream the Dodgers online, or using ESPN's mobile apps available on iOS and Android. That also means you can find a friend who has cable, and team up with them to watch online — or just hang out at their place for the foreseeable future.

Many other Dodgers games throughout the season will be on SportsNet L.A., but you have to subscribe to Charter Spectrum, Time Warner, or Bright House in the L.A. area to get this channel. However, five of the games this season will be shown on KTLA, expanding your options for potentially checking the Dodgers out. You can find out more in the SportsNet L.A. FAQ.

How are you tracking the Dodgers? Let us know in the comments or by tweeting us at @KPCC.

When he died in 2013, Sal Castro drew praise as a Southern California civil rights leader who championed educational opportunities for generations of students of Mexican descent.

While a high school teacher in 1968, he helped thousands of students stage massive walkouts in Los Angeles' east side to protest high dropout rates and poor schooling that ignored their cultural background.

Supporters say his most influential legacy is the Chicano Youth Leadership Conference that he founded in 1963 as a weekend camp in the Santa Monica mountains. The gathering functioned as a cultural pep rally and intensive college application session.

“There was quite a large group of people that knew that this is not something that could die with him. That is when we had the idea to form a foundation to make sure that we keep his legacy alive,” said Myrna Brutti, the conference’s director.

Castro struggled to raise money for the conference, which counts among its alumni such well-known leaders as former Los Angeles Mayor Antonio Villaraigosa and filmmaker Moctesuma Esparza.

The Sal Castro Foundation typically spends about $60,000 to pay for the camp, including food and bus transportation. The group raises the money so that students can attend for free.

Applications to the next conference on March 6 have been sent to LAUSD high school campuses, targeting low-income Latinos, with a Feb. 20 deadline. Organizers hope in years ahead to open the conference to other Southland schools.

Brutti, a middle school principal, said she sees many more college application and high school to college bridge programs today. But a large group of high school students still go without college counseling, she said.

“These are 4.0, 3.7, 3.9, 4.2 [grade-point average] students that graduate from high school and go directly into the workforce because no one has taken the time to really go in depth on…what is available to them,” Brutti said.

The conference gives students like high school junior Savannah Pierce a broader view of their post-graduation choices. She attended the conference in October.

“I never really gave much thought to getting a doctorate degree,” Pierce said. “I thought I was going to do my four years of undergraduate and maybe graduate school. I never realized how many options and opportunities there were.”

When Castro talked to students of Mexican descent, he often transitioned seamlessly between English and Spanish, giving brief lessons on Mexican history and notable Mexicans. The current conference leaders are keeping that tradition alive.

“I never realized how deep and important my culture is and how rich it is with knowledge, and how hard people have worked in the past to get me where I am today,” Pierce said.

Other resources for students seeking help with college applications include:

2. The College Board’s college planning helper

3. The Princeton Review’s college helper

On August 17, 2017, scientists made history with the first direct observation of a merger between two neutron stars. It was the first cosmic event detected in both gravitational waves and the entire spectrum of light, from gamma rays to radio emissions. The impact also created a kilonova -- a turbocharged explosion that instantly forged several hundred planets’ worth of gold and platinum. The observations provided the first compelling evidence that kilonovae produce large quantities of heavy metals, a finding long predicted by theory. Astronomers suspect that all of the gold and platinum on Earth formed as a result of ancient kilonovae created during neutron star collisions. Based on data from the 2017 event, first spotted by the Laser Interferometer Gravitational-wave Observatory (LIGO), astronomers began to adjust their assumptions of how a kilonova should appear to Earth-bound observers. A team of scientists reexamined data from a gamma-ray burst spotted in August 2016 and found new evidence for a kilonova that went unnoticed during the initial observations.
