This article aims to encourage practitioners, young and seasoned, by enhancing their structure-determination toolboxes with a selection of tips and tricks on recognizing and handling aspects of data collection, structure modelling and refinement, and the interpretation of results.

The development of antiviral strategies requires a clear understanding of the principles that control the protein arrangements in viral shells. Considered here are those capsids that violate the paradigmatic Caspar and Klug (CK) model, and it is shown that the important structural features of such anomalous shells from the Picobirnaviridae, Flaviviridae and Leviviridae families can be revealed by models in the form of spherical icosahedral packings of equivalent rhombic structural units (SUs). These SUs are composed of protein dimers forming the investigated capsids which, as shown here, are based on the rhombic triacontahedron (RT) geometry. How to modify the original CK approach in order to make it compatible with the considered rhombic tessellations of a sphere is also discussed. Analogies between capsids self-assembled from dimers and trimers are demonstrated. This analysis reveals the principles controlling the localization of receptor proteins (which recognize the host cell) on the capsid surface.

In small-molecule single-crystal structure determination, we now have at our disposal an inspiring range of fantastic diffractometers with better, brighter sources, and faster, more sensitive detectors. Faster and more powerful computers provide integrated tools and software with impressive graphical user interfaces. Yet these tools can lead to the temptation not to check the work thoroughly and one can too easily overlook tell-tale signs that something might be amiss in a structure determination; validation with checkCIF is not always revealing. This article aims to encourage practitioners, young and seasoned, by enhancing their structure-determination toolboxes with a selection tips and tricks on recognizing and handling aspects that one should constantly be aware of. Topics include a pitfall when setting up data collections, the usefulness of reciprocal lattice layer images, processing twinned data, tips for disorder modelling and the use of restraints, ensuring hydrogen atoms are added to a model correctly, validation beyond checkCIF, and the derivation and interpretation of the final results.

What an animal eats is a fundamental aspect of its biology, but surprisingly, the evolution of diet had not been studied across the animal kingdom until now. Scientists at the University of Arizona report several unexpected findings from taking a deep dive into the evolutionary history of more than one million animal species and going back 800 million years, when the first animals appeared on our planet. The study revealed several surprising key insights: Many species living today that are carnivorous, meaning they eat other animals, can trace this diet back to a common ancestor more than 800 million years ago; A plant-based, or herbivorous, diet is not the evolutionary driver for new species that it was believed to be; Closely related animals tend to share the same dietary category -- plant-eating, meat-eating, or both. This finding implies that switching between dietary lifestyles is not something that happens easily and often over the course of evolution.

"Live! Life's a banquet and most poor suckers are starving to death!" - Auntie Mame.

Your calendar is filling up, but here are four holiday events you'll want to make room for:

Every year, pioneering Chicano artist Frank Romero and his wife Sharon throw a big studio sale that includes works by a wide group of artists, and a lot of food and drink. It's just as much a party as a sales event, and Frank and the other artists are always there to meet and greet. And now that the couple is spending more time at their home in France, it's a chance for their old friends to catch up with them, so who knows who you'll see from L.A.'s arts community.

RELATED: See Frank's new works - French scenes with an East LA flavor

The Romero Studio annual Christmas party and sale is Saturday, Dec. 6, 6-10pm; and Sunday, Dec. 7, 1-5pm, at Plaza de la Raza, Boathouse Gallery, 3540 North Mission Rd., LA CA 90031 (in Lincoln Park across from the DMV — which BTW is a very good DMV).

Then, on Sunday, Dec. 14, at 4:30pm,  it's the Advent Procession of Lessons and Carols, at St. James Episcopal Church, which a friend describes as "one of the truly beautiful choral events of the season," and the highlight of the Choir of St. James' season. It's free and it's at St. James' Episcopal Church in Koreatown (3903 Wilshire Blvd., Los Angeles 90010).
 

"Auntie Mame," the 1958 Rosalind Russell movie with more quotable quips than a weekend getaway with Oscar Wilde, has become something of a Christmas tradition. It's screening at the American Cinematheque's Egyptian Theatre on Wednesday, Dec. 17, at 7:30. As delightful as this movie is any day of the week on your TV at home, this is a film to be seen in 35mm with a theater full of people reacting to every bon mot and heart-touching moment.

GO INSIDE: The Disney Hall organ, "Hurricane Mama," turns 10

Last year, my husband and I blindly went to Disney Hall for the Holiday Organ Spectacular. We expected some music and a little fun. But it really was spectacular. It's back this year, on Friday, Dec. 19, with organist David Higgs leading the evening from the console of Hurricane Mama.

If you've never seen or heard the organ in person, this is a great evening because Higgs — a teacher as well as master organist — gives you a guided tour of every stop, and every mood the organ can produce, from cathedral-loud to country-church-quiet. At the end of the night, he breaks the audience into parts to sing "The Twelve Days of Christmas," and you may sing as loud as you like.

These are just a few curated selections, but they're just the tip of the iceberg in Southern California; please make your own holiday event recommendations in the comments below.

When Congress allocated money for higher education in the coronavirus rescue package, it set aside nearly $350 million for colleges that had "significant unmet needs."

Most of that money has now been allotted by the U.S. Department of Education to small, private colleges that serve just a fraction of U.S. college students. Meanwhile, public colleges — which serve more than 70% of all college students — are facing a steep drop in state funding.

The 20 institutions that received the most amount of money from the unmet-need fund serve less than 3,000 students combined, and about half are religious schools — including Bible colleges and seminaries — several of which serve less than 100 students.

Lawmakers designed this unmet-need fund to give priority to any higher education institution that has received less than $500,000 through the CARES Act's other pots of funding. As a result, a school like Virginia Beach Theological Seminary, which serves 47 students, is eligible to receive $496,930 in federal aid.

"Imagine you had a special reserve fund to deal with a big crisis and you spent over 90% of that in one fell swoop on vacation tickets," or something that "wasn't as necessary in the moment," says Ben Miller, the vice president for postsecondary education at the left-leaning Center for American Progress. Miller argues larger public colleges, including community colleges that serve tens of thousands of students, should be getting more financial support. He calculates the department allocated more than $320 million of the $350 million on relief for small colleges, most of them private.

"As a result, they only have about 8% of the dollars they originally got here left to help any other college in the country that might be most affected," he says.

As with other CARES Act funding, in order to receive the money, an institution would still need to request it from the Department of Education.

Much of the CARES Act's more than $14 billion for higher education is being distributed according to the number of full-time low-income students a college serves, which is measured through federal Pell Grants.

The $350-million unmet-need fund followed a different formula. Miller says for this particular pot, schools that did not receive $500,000 or more from other available CARES Act funds were given the difference between what they did receive and $500,000 limit.

"So the result is that the smaller you are and the less money you've already gotten, the more you get from this program," Miller says.

But $350 million can only go so far. Education Secretary Betsy DeVos was given the discretion to choose which schools would benefit from the fund, and by how much.

Some schools were baffled when they learned they had been allotted hundreds of thousands of dollars in relief, and many weren't aware they were even eligible for the money. Brad Smith, the president of Bakke Graduate University in Dallas, which was allotted $497,338 in federal aid, says he didn't learn of his school's eligibility until he was contacted by NPR.

"I don't know anything about this," Smith says, noting that his school hadn't asked for additional federal help. "I'm taking responsibility to find out what it means."

An Education Department spokesperson tells NPR, "In order to receive this funding, an institution will need to request it. Any institution that does not need this money should simply decline to request it so schools will not be in the position of having to return unneeded funds."

The department says, once the requests are processed, any remaining funds will be redistributed through competitive grants.
