A new Smithsonian study that examines 10 million years of the evolution of tiny coral-like organisms called cupuladriid bryzoans has revealed that some species of this organism lingered on earth for more than one million years after the event that ultimately caused their extinction: the rising of the Isthmus of Panama.

When you look at fast growing private companies in the U.S., you need look no further than a small city next to Los Angeles International Airport.

Steve Julian: Business analyst Mark Lacter, tell us about the company that's based in El Segundo.

Mark Lacter: It's called Fuhu, Steve - that might ring a bell with some parents because Fuhu is the maker of the Nabi.  The Nabi is an Android tablet for kids, and it's a very cool device that mimics a lot of the capabilities of regular tablet, including the ability to play games and get onto the Web (with controls that parents are able to set up).  Last year, they sold 1.2 million Nabis, and that helped push the El Segundo company to the very top of Inc. magazine's list of fastest-growing businesses.  That's number one on a list of 5,000 companies, with a three-year growth rate of 42,148 percent.  Or, to put it another way, company revenue was $279,000 in 2009; it was almost $118 million in 2012.  Now, by the standards of an Apple or a Samsung, those are still not huge numbers -

Julian: - and maybe that explains why there's been relatively little media coverage of this company.

Lacter: It might also explain why local tech companies in general get short shrift.  Many of them are quite successful, but they're often on the small side, and they're also privately held as opposed to publicly-traded on a stock exchange.  That's one big difference from Silicon Valley, which has so many huge public corporations: Apple, Intel, HP.  L.A. County has only six Fortune 500 companies, and not a single one devoted solely to technology.  In Silicon Valley, there are 22 in the Fortune 500.

Julian: And yet, the L.A. economy has more than held its own without those large corporations.

Lacter: Matter of fact, the accounting firm PriceWaterhouse studied more than two dozen cities around the world to determine where it was easiest to do business (that's based on factors like access to labor), and what they found - somewhat surprisingly - was that L.A. ranked ahead of both San Francisco and Tokyo.  And, you can see evidence of that with the increase in venture capital money coming into all parts of L.A.  Now, it's important to keep an eye on all these up-and-coming companies because these businesses are helping generate higher-wage jobs.  And, for an area with a still-high unemployment rate - still over 10 percent in some places -- that's a big deal.

Julian: Speaking of companies, does anyone want to buy the L.A. Times?

Lacter: The answer is yes - most recently, the controlling owner of the Dodgers, Mark Walter, said he was interested in both the Times and the Chicago Tribune (though there's no way to know whether there are actual discussions taking place).  You also have several local groups, including one that involves billionaire Eli Broad, that have been interested to one degree or another.  But what was thought would be a fairly straightforward auction process has turned enormously complicated.  It's now to the point where the Tribune board has decided spin off the papers into a separate business, and that process will take until next year to complete and could preclude any sales for quite some time after that.

Julian: So, it's Limbo-land for the Times for who knows how long.

Lacter: Steve, it's not that Tribune really wants to keep the newspapers.  But, selling them off presents huge tax implications.  Also, there are assets that the potential buyers thought would be part of the package - assets that include real estate - that Tribune wants to hold onto.  So, what's left to sell are just the newspapers themselves, and frankly, they're among the least valuable properties.

Julian: Now, last week came word that the billionaire Koch brothers, who were believed to be interested in the Tribune properties, decided not to pursue a deal...

Lacter: ...that's right, they don't consider the Times or the other dailies to be economically viable.  You might recall a bit of an outcry over the prospect of having the Kochs, who are staunch conservatives, becoming the owners of these papers.  So, they're out of the picture.  But for the L.A. Times, it's really the worst of all worlds: no new owner and no vision for recasting the paper, at least in the near term.

In the first reported crystal structure involving the potential ligand N,N',N''-tris­(2-pyridin­yl)-1,3,5-benzene­tricarboxamide, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules via their amide groups into slanted ladder-like chains. Only two of the three amide groups in the mol­ecule are involved in hydrogen bonding, which influences the degree of out-of-plane twisting at each amide group.

The cationic cyclo­metallated iridium(III) complex [Ir(C9H7N2)2(C12H8N2)](PF6) has been synthesized and crystallized by the inter-diffusion method. It contains an unknown number of solvent mol­ecules and has a different space-group symmetry (C2/c) structure than its solvatomorph (P21/c).

The title compound exhibits exceptionally weak inter­molecular C—H⋯π hydrogen bonding of the ethynyl groups, with the corresponding H⋯π separations [2.91 (2) and 3.12 (2) Å] exceeding normal vdW distances. This bonding compliments distal contacts of the CH (aliphatic)⋯π type [H⋯π = 3.12 (2)–3.14 (2) Å] to sustain supra­molecular layers.

In a Model block, if the instance-specific value of a model argument has an anonymous structure type, an update diagram reports an error when there are multiple bus types that match that anonymous structure type.This bug exists in the following release(s):

In the title compound, C16H14Cl2FN3, the dihedral angle between the two aromatic rings is 64.12 (14)°. The crystal structure is stabilized by a short Cl...H contact, C—Cl...π and van der Waals interactions. The Hirshfeld surface analysis and two-dimensional fingerprint plots show that H...H (33.3%), Cl...H/H...Cl (22.9%) and C...H/H...C (15.5%) interactions are the most important contributors towards the crystal packing.

The title compound, C14H16, exhibits exceptionally weak intermolecular C—H...π hydrogen bonding of the ethynyl groups, with the corresponding H...π separations [2.91 (2) and 3.12 (2) Å] exceeding normal vdW distances. This bonding complements distal contacts of the CH (aliphatic)...π type [H...π = 3.12 (2)–3.14 (2) Å] to sustain supramolecular layers. Hirshfeld surface analysis of the title compound suggests a relatively limited significance of the C...H/H...C contacts to the crystal packing (24.6%) and a major contribution from H...H contacts accounting 74.9% to the entire surface.

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.
