Growing high-quality crystals remains a necessary part of crystallography and many other techniques. This article tabulates and describes several techniques and variations that will help individuals grow high-quality crystals in preparation for crystallographic techniques and other endeavors, such as form screening. The discussion is organized to focus on low-tech approaches available in any laboratory.

Catalase is an antioxidant enzyme that breaks down hydrogen peroxide (H2O2) into molecular oxygen and water. In all monofunctional catalases the pathway that H2O2 takes to the catalytic centre is via the `main channel'. However, the structure of this channel differs in large-subunit and small-subunit catalases. In large-subunit catalases the channel is 15 Å longer and consists of two distinct parts, including a hydrophobic lower region near the heme and a hydrophilic upper region where multiple H2O2 routes are possible. Conserved glutamic acid and threonine residues are located near the intersection of these two regions. Mutations of these two residues in the Scytalidium thermophilum catalase had no significant effect on catalase activity. However, the secondary phenol oxidase activity was markedly altered, with kcat and kcat/Km values that were significantly increased in the five variants E484A, E484I, T188D, T188I and T188F. These variants also showed a lower affinity for inhibitors of oxidase activity than the wild-type enzyme and a higher affinity for phenolic substrates. Oxidation of heme b to heme d did not occur in most of the studied variants. Structural changes in solvent-chain integrity and channel architecture were also observed. In summary, modification of the main-channel gate glutamic acid and threonine residues has a greater influence on the secondary activity of the catalase enzyme, and the oxidation of heme b to heme d is predominantly inhibited by their conversion to aliphatic and aromatic residues.

The reaction of Co(NCS)2 with 4-methyl­pyridine N-oxide (C6H7NO) leads to the formation of two compounds, namely, tetra­kis­(4-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II), [Co(NCS)2(C6H7NO)4] (1), and tris­(4-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II), [Co(NCS)2(C6H7NO)3] (2). The asymmetric unit of 1 consists of one CoII cation located on a centre of inversion, as well as one thio­cyanate anion and two 4-methyl­pyridine N-oxide coligands in general positions. The CoII cations are octa­hedrally coordinated by two terminal N-bonding thio­cyanate anions in trans positions and four 4-methyl­pyridine N-oxide ligands. In the extended structure, these complexes are linked by C—H⋯O and C—H⋯S inter­actions. In compound 2, two crystallographically independent complexes are present, which occupy general positions. In each of these complexes, the CoII cations are coordinated in a trigonal–bipyramidal manner by two terminal N-bonding thio­cyanate anions in axial positions and by three 4-methyl­pyridine N-oxide ligands in equatorial positions. In the crystal, these complex mol­ecules are linked by C—H⋯S inter­actions. For compound 2, a nonmerohedral twin refinement was performed. Powder X-ray diffraction (PXRD) reveals that 2 was nearly obtained as a pure phase, which is not possible for compound 1. Differential thermoanalysis and thermogravimetry data (DTA–TG) show that compound 2 start to decompose at about 518 K.

The title compound, [Ni(NCS)2(C6H7N)2]n, was prepared by the reaction of Ni(NCS)2 with 4-methyl­pyridine in water. Its asymmetric unit consists of two crystallographically independent NiII cations, of which one is located on a twofold rotational axis whereas the second occupies a center of inversion, two independent thio­cyanate anions and two independent 4-methyl­pyridine co­ligands in general positions. Each NiII cation is octa­hedrally coordinated by two 4-methyl­pyridine coligands as well as two N- and two S-bonded thio­cyanate anions. One of the cations shows an all-trans, the other a cis–cis–trans configuration. The metal centers are linked by pairs of μ-1,3-bridging thio­cyanate anions into [101] chains. X-ray powder diffraction shows that a pure crystalline phase has been obtained and thermogravimetry coupled to differential thermoanalysis reveals that the title compound loses half of the 4-methyl­pyridine coligands and transforms into Ni(NCS)2(C6H7N). Nearly pure samples of this compound can be obtained by thermal annealing and a Rietveld refinement demonstrated that it is isotypic to its recently reported Cd analog [Neumann et al., (2020). CrystEngComm. 22, 184–194] In its crystal structure, the metal cations are linked by one μ-1,3(N,S)- and one μ-1,3,3(N,S,S)-bridging thio­cyanate anion into single chains that condense via the μ-1,3,3(N,S,S)-bridging anionic ligands into double chains.

Reaction of copper(I)chloride with 2,3-di­methyl­pyrazine in ethanol leads to the formation of the title compound, poly[[μ-chlorido-μ-(2,3-di­methyl­pyrazine)-copper(I)] ethanol hemisolvate], {[CuCl(C6H8N2)]·0.5C2H5OH}n or CuCl(2,3-di­methyl­pyrazine) ethanol hemisolvate. Its asymmetric unit consists of two crystallographically independent copper cations, two chloride anions and two 2,3-di­methyl­pyrazine ligands as well as one ethanol solvate mol­ecule in general positions. The ethanol mol­ecule is disordered and was refined using a split model. The methyl H atoms of the 2,3-di­methyl­pyrazine ligands are also disordered and were refined in two orientations rotated by 60° relative to each other. In the crystal structure, each copper cation is tetra­hedrally coordinated by two N atoms of two bridging 2,3-di­methyl­pyrazine ligands and two μ-1,1-bridg­ing chloride anions. Each of the two copper cations are linked by pairs of bridging chloride anions into dinuclear units that are further linked into layers via bridging 2,3-di­methyl­pyrazine coligands. These layers are stacked in such a way that channels are formed in which the disordered solvent mol­ecules are located. The topology of this network is completely different from that observed in the two polymorphic modifications of CuCl(2,3-di­methyl­pyrazine) reported in the literature [Jess & Näther (2006). Inorg. Chem. 45, 7446–7454]. Powder X-ray diffraction measurements reveal that the title compound is unstable and transforms immediately into an unknown crystalline phase.

The original cast of The Cosby Show. ; Credit: Frank Carroll/Associated Press

Thirty years ago, on September 20,"The Cosby Show" debuted on NBC and went on to dominate our screens for almost a decade.

The award-winning sitcom introduced us to the Huxtables, an upper-middle class black family  made up of Heathcliff, Clair and their five children. Plus a cast of ugly sweaters.

"The Cosby Show" covered familiar territory; from children getting body piercings, bad boyfriends and maintaining a long term relationship as parents with professional lives.

Speaking to Take Two's Alex Cohen, Mark Anthony Neal, professor of African and African American Studies at Duke University said "The Cosby Show" broke down racial stereotypes.

"It  really was the first program to present not just a middle class, or upper-middle class black family, but a professional family. Clair and Heathcliff Huxtable were educated, they had advanced degrees. It was an image we hadn't seen before."

From 1985 to 1990, "The Cosby Show" held the number one spot in the TV ratings war, appealing to audiences across color lines. Black viewers in particular welcomed a broader representation of African American life on screen, building on the success of shows such as "The Jeffersons", "Sanford and Son" and "Good Times". 

"Bill Cosby was very honest about the fact that when he conceived the character of Heathcliff Huxtable, he was looking for images that countered, say, Fred Sanford who was a junk dealer, or James Evans, Jr. in 'Good Times' who was always struggling to find a job. Bill Cosby wanted to bring a different view of the black family into the mix."

Despite its popularity, some people took issue with how "The Cosby Show" tackled race issues.

"It's not that black Americans didn't enjoy the show, but there were criticisms because it didn't explore the broader world of African Americans." says Professor Neal. "The Huxtable family became a stand in for the successes of the civil rights movement. It became the rationale that if the Huxtables can do it, why can't other African Americans do it?"

Today's media landscape is very different to the one "The Cosby Show" existed in. For this reason, says Professor Neal, its success has been difficult to replicate.

"Right after it went off the air, cable TV takes hold and we get this niche programming.  Many African American programs ended up on Fox, UPN and the WB, so there was no incentive for the major networks to do any Cosby-like programming with a black family at the center."

With the debut of ABC's "Blackish" on September 24, it's hoped this will go some way to fill the Cosby-shaped void. In the meantime there's always YouTube and re-runs. Just be thankful Heathcliff's ugly sweaters are a thing of the past.

Off-Ramp producer Queena Kim acts on behalf of millions of Angelenos. The meter didn't stand a chance.

Off-Ramp began eleven years ago, just as digital technology was beginning to overtake radio. No more cassette tape or mini-discs; host John and producer Queena Kim thought they could take on all of Los Angeles with two digital audio recorders and a different approach to public radio.

Short-handed as they were, John and Queena had to adopt slash-and-burn tactics to get each show produced on time. The majority of interviews were conducted in the field; at the homes, workplaces, and favorite hang-outs of their subjects (instead of waiting for guests to come to the station) and many of the stories were edited as simple two-way interviews with life in Southern California picked up as ambient, background noise. After all, a show called Off-Ramp had better be ready to brave some LA traffic.

At this juncture, John feels free to say what he has always wanted to, but hasn't for fear of self-aggrandizement: "I think we were trendsetters. I think Marketplace and NPR heard the stuff we were doing, and started doing stuff like it." Once again, Kim chalks it up to being in the right place at the right time technologically, and the two person team's willingness to break out of the old-school, public radio way writing a story: with a very clear sonic difference between studio narration and field audio.

Of course, it wasn't just Marantz recorders and minimal rewriting that gave Off-Ramp its flavor. There was a whole lot of weird spewing up out of Los Angeles during the show's formative years and Kim's tenure (2006-2010). She recalls covering a ten-theremin orchestra at Disney Hall, and the excitement of working on a show that let her (and the listeners, vicariously) do things she always wanted to do. "It was almost like having a free pass to the city."

In order to capture what was new and exciting, John and Queena both agree that it was absolutely vital to abandon the reporter's instinct for safely packaging the story ahead of time. John cites his editor at Minnesota Public Radio's philosophy, Mike Edgerly; "Go find what the story is, go out and explore and figure out what the story is. Don't figure it out at your desk first." The collaboration between John's ideas and Kim's sense of logistics formed a dialectic relationship, valuing the "third, better idea" over either of their original perspectives. In light of that, John says Queena Kim was the perfect person with whom to start Off-Ramp.

UPDATE: “Allegiance” will be performed Feb. 21-April 1, 2018, at the Aratani Theater at the Japanese Cultural and Community Center in downtown L.A.'s Little Tokyo.

ORIGINAL STORY: In an intimate interview, George Takei tells Off-Ramp host John Rabe about crafting the Japanese-American internment camp history into compelling Broadway musical theater. "Allegiance," with Takei, Lea Salonga and Telly Leung, played at the Longacre Theater.

George Takei and his husband Brad were putting their house in mothballs when I arrived for our interview in August. They'd already been spending a lot of time in New York because of George's recurring role on "The Howard Stern Show," but now, with the Broadway opening of "Allegiance" just a couple months away, they were preparing to move for as long as the musical brings in the crowds.

While Brad went off to deal with the mundane domestic tasks around the move, I sat with George in their living room to talk about turning one of America's most shameful episodes — the internment of some 120,000 loyal Japanese-Americans during World War II — into a musical that could make it on the Broadway stage.

George, you just sent an email to your fans with the subject line: "I've Waited 7 Years to Send You this Email. Seven years!" Inside, you wrote: "Few things are as difficult and complex as taking a show to ‪Broadway‬. It's both thrilling and terrifying." What was terrifying?

"The terrifying part is, you've poured your passion, your energy, your resources ...  you make all that investment in that project, and then you're hoping the seats are going to be filled.That 'what if' is terrifying. But in San Diego, we had a sold-out run and broke their 77-year record. But now we're going to Broadway, and that same fear is there. Will they come? What will the critics say? Because it's life or death."

It took a long time just to get a Broadway theater.

"It took a long time to get a theater.You think there are a lot of Broadway theaters, but there are even more productions that want those chunks of New York real estate. So we thought we'd get in line. But then the other discovery we made is that the theater owners have relationships with grizzled old producers who have brought them a vast fortune with enormous hits, and they can cut in line. They have a track record. And so, 'will we ever get a theater' became a big question. But we have this time now — let's use it creatively, productively."

So, Takei says, the team tweaked the show, removing parts that didn't work didn't advance the story, inserting numbers that worked better and kept the story moving. They doubled down on social media, building and proving demand in the show.

"We have a Shubert theater (the Longacre), and Bob Wankel is head guy there, and I remember pouring my heart out, telling the story of my parents, hoping that touches. And he was understanding, but I understood his problem, too. Everybody is trying to get a theater and he has to make a good business decision and was initially skeptical. An internment camp musical? But music has the power to make an anguished painful situation even more moving, even more powerful. It hits you in the heart."

Highlights from "Allegiance" at the Old Globe in San Diego

This is your Broadway debut, right? Are you petrified?

"Yes, yes. I've done a lot of stage work, and I've done a lot of public speaking, but it's Broadway, and I'm a debutante... at 78 years old! And it's the critics, too. The New York Times, Ben Brantley. That's who I'm going to be facing, and so it's both exciting and absolutely filling me with ecstasy, but what makes it ecstatic is the fear."

Moderna says recently completed studies have found its vaccine to have a neutralizing effect against all COVID-19 variants tested, including the delta variant.; Credit: Fred Tanneau/AFP via Getty Images

Studies have found that Moderna's COVID-19 vaccine is effective against several variants of concern, including the delta variant, the biotech company announced.

Moderna said Tuesday that recently completed studies have found the vaccine to have a neutralizing effect against all COVID-19 variants tested, including the beta, delta, eta and kappa variants.

While still highly effective against the delta variant, the study showed the vaccine was less effective against it and certain other variants than against the original strain of the virus.

The antibody response against the delta variant was about two times weaker than against the ancestral strain of the virus.

The news echoes other findings that the Moderna and Pfizer vaccines are highly effective against the delta variant. A study published this month in Nature found that Pfizer's vaccine was able to neutralize variants including delta, though at somewhat reduced strength.

"These new data are encouraging and reinforce our belief that the Moderna COVID-19 Vaccine should remain protective against newly detected variants," Stéphane Bancel, Moderna's chief executive officer, said in a statement. "These findings highlight the importance of continuing to vaccinate populations with an effective primary series vaccine."

The company also said it is developing a booster candidate: a 50-50 mix of its currently authorized COVID-19 vaccine and another messenger RNA vaccine it has developed.

The delta variant is spreading fast

The delta variant is the fast-moving form of the coronavirus that is now found in 96 countries, including the United States.

Last week, Dr. Anthony Fauci of the National Institutes of Health said the delta variant is "currently the greatest threat in the U.S. to our attempt to eliminate COVID-19," noting that the proportion of infections being caused by the variant is doubling every two weeks.

The delta variant is now infecting at least 1 out of every 5 people who get the virus in the United States. In some sections of the country, the variant is already far more common, particularly in parts of the Midwest and West. At its current pace, the delta variant is expected to be the dominant virus in the U.S. within weeks.

Dr. Maria Van Kerkhove, an infectious disease expert at the World Health Organization, called the delta variant "incredibly transmissible."

"These viruses are becoming more fit. The virus is evolving, and this is natural," she told NPR's Morning Edition. "It's more transmissible than the alpha variant, so we need to just do all we can to prevent as many infections as we can and do what we can do to reduce the spread."

Pennsylvania’s highest court overturned. Bill Cosby’s sex assault conviction Wednesday after finding an agreement with a previous prosecutor prevented him from being charged in the case.

Cosby has served more than two years of a three- to 10-year sentence at a state prison near Philadelphia. He had vowed to serve all 10 years rather than acknowledge any remorse over the 2004 encounter with accuser Andrea Constand.

We dive into how this all happened, through the lens of law, celebrity and the MeToo movement.
