When talk turns to the economy, it's clear that LA brings out the best and the worst.

Steve Julian: Business analyst Mark Lacter, where do you see the best of it here?

Mark Lacter: You see the best of the economy, Steve, with all kinds of startup activity - much of it tech-related - and you also see the large number of auto sales, the improved housing market, and the record number of people visiting Southern California - all indications of a growing economy.  But then, you have the other L.A. economy, with large numbers of families struggling to make ends meet, and seeing very little sign of recovery.  You know, the government has been releasing income data covering the last few years, and what you see is that the disparity between the richest 1 percent and the other 99 percent is at its widest point since the 1920s.  You especially see that kind of bifurcated economy in Southern California, which has some of the wealthiest people in the country, and also some of the poorest.

Julian: Now, the split between rich and poor has been happening for a good long time, hasn't it?

Lacter: Yes, but L.A. is in a special class because there are so many immigrants with limited job skills - in fact, a new study by the UCLA Anderson Forecast says it's a much higher percentage than immigrants living in Miami, San Francisco, and New York.  What's interesting is that 20 years ago the job skills among immigrants were significantly higher in L.A.  Limited job skills mean there's very little opportunity to move up the income ladder.  That factors into buying homes, sending your kids to college - really becoming part of the middle class.

Julian: I imagine that's particularly true for factory work…

Lacter: Yes, some of the same jobs that newly-arrived immigrants in previous generations would gravitate to.  Today, many of those jobs are gone, and they're being replaced by positions that require greater skill that's borne out of greater education.  And that, of course, is another problem: a sizable percentage of recently-arrived immigrants never finished high school, much less college, and that makes it even less likely that they'll be able to move up.

Julian: Related, or unrelated, to the recession?

Lacter: Actually, L.A. had serious income inequality in December of 2006, before the recession, when the county's unemployment rate was just 4.3 percent - a stunningly low rate when you consider that as of July, the jobless rate was almost 10 percent.  This points out that the division of haves and have-nots can happen even when the economy is doing well.

Julian: And it seems the last C-17 to be built for Air Force is a reminder of wage gap.

Lacter: That's right - it'll be up to foreign customers to keep the program in Long Beach alive.  Boeing currently has an order from India for 10 of the cargo planes, which will keep the line moving through the third quarter of next year.  Frankly, the only reason the C-17 has lasted this long is heavy political pressure by congressional lawmakers whose districts have an economic stake in the program.  At one time, as many as 16,000 people may have worked on the C-17 in Long Beach, but that number has fallen sharply over the years.

Julian: Still, this is the last airplane manufacturing plant in Southern California.

Lacter: And that, of course, speaks volumes about the state of the aerospace business, which had been one of the main economic drivers back in the days leading up to World War II.  Aerospace continued to be very important until the end of the Cold War, when you had a huge industry consolidation that resulted in the loss of tens of thousands of local jobs throughout the 1990s.  There's still quite a bit of aerospace activity locally that involves missiles, satellites, and electronics - both for the major defense contractors like Boeing and Northrop, and for smaller contractors and sub-subcontractors that still get a piece of the military pie.

Julian: But most of them require high skill levels…

Lacter: Yes, and that gets us back to the folks who are stuck in low-paying jobs with little prospect for moving up.  This is what the L.A. economy is all about, the good and the bad.

The contamination of Foster Farms chickens has provided insight into food regulation.

Steve Julian: Business analyst Mark Lacter, had we been paying attention before this happened?

Mark Lacter: You know, Steve, we often have an out of sight, out of mind attitude when it comes to food safety, and - as we're seeing with this episode - the government has a way of enabling that attitude.  What stands out, first of all, is that people started getting sick from salmonella-contaminated chicken back in March, and yet, it wasn't until the past few weeks that news stories began appearing about the seriousness of the problems.

Julian: At last check, more than 400 people have been infected, with most of them in California...

Lacter: Right, and Foster Farms, which is based in Merced County, controls two-thirds of the poultry market along the West Coast.  No fatalities so far, but many of the people who became sick had to be hospitalized - and that leads to still more concerns that the salmonella strains were resistant to antibiotics.  Now, why it took this long for consumers to be made aware that there was a problem tells you something about the way the federal government regulates poultry plants.  It was only last Friday, after the company had seen a 25 percent drop in sales, when the president of Foster Farms decided to go public.  He said he was embarrassed by the outbreak, and promised to change the company's processing facilities so that salmonella can be better identified.

Julian: Where was the US government in this?

Lacter: Apparently, the Department of Agriculture only requires testing for levels of salmonella at the time of slaughter - not later on, after the poultry is cut into parts.  Foster Farms now says it will do retesting at that later stage.  What's also interesting is that Foster Farms was not asked to recall any of its products because the chicken is considered safe as long as it's handled properly and then cooked to the right temperature, which is at least 165 degrees.  That's why some supermarkets have kept carrying the brand.

Julian: Can the government even order a recall?

Lacter: Not in a case like this - and that's because of a court case in the 1990s involving a Texas meat producer that federal inspectors were ready to shut down due to a salmonella outbreak involving ground beef.  The company sued the government, arguing that salmonella is naturally occurring, and therefore, not an adulterant subject to government regulation.  And the courts agreed.  Foster Farms has been using much the same argument.

Julian: Why isn't there more public outrage over this?

Lacter: Well, again, we go back to out of sight, out of mind.  Slaughterhouses are not exactly fun places, and they're usually not well covered by the news media until something bad happens, like the Foster Farms situation.

Julian: Chino comes to mind - a story we covered.

Lacter: That's when an animal rights group used a hidden camera to record inhumane treatment of cattle at a meat processing plant.  That company was forced into bankruptcy.  Another reason coverage is spotty is because it's not always easy to trace someone's illness to a contaminated piece of meat or chicken.  And, that leads to lots of misinformation.  The broader issue is figuring out a way to monitor these facilities without the process becoming cost prohibitive.  The Agriculture Department has been pushing a pilot program that would allow plants to speed up processing lines, and replace government inspectors with employees from the poultry companies themselves.

Julian: The idea being?

Lacter: The idea being to establish safeguards that can prevent problems before they get out of hand.  But, this is pretty controversial stuff, and advocacy groups representing poultry workers say that processing lines need to be slowed down, not speeded up.  So, you have this ongoing back and forth involving industry, government, consumer groups, and labor organizations.  And unfortunately, most of us tend to move on after one of these outbreaks gets cleared up.

Yesterday may have been a holiday on paper, but if you were navigating LA's major freeways, there was no sign people had the day off.

Steve Julian: Business analyst Mark Lacter, is this more evidence that Southern California traffic getting worse?

Mark Lacter: Steve, L.A. continues to be the most clogged-up city in the U.S. - according to something called the TomTom Traffic Index - with commuters caught up in delays, on average, 35 percent of the time.  Or, to put it another way, L.A. commuters are in congestion up to 40 minutes of each hour they're driving.  The worst time of the week to commute is Thursday night; that's when there's congestion more than 80 percent of the time.  Monday morning commutes are the lightest.

Julian: After L.A., where should you not live if congestion bugs you?

Lacter: The next worst cities in the U.S. are San Francisco, Honolulu, Seattle, and San Jose.  Now, the Census Bureau comes up with its own commuting surveys, and if you compare the most recent numbers with those back in 2000, you'll see that things aren't all that different.  Matter of fact, the percentage of commuters driving alone to work actually increased a little over the last decade to 72 percent, while the percentage of those carpooling has declined.

Julian: What about public transit?

Lacter: Well, the numbers are up slightly from 2000, but only to 7.3 percent of all commuters.  So, even assuming that the number inches up in the next couple of years when the Expo Line extends into Santa Monica, it's still a smallish piece of the pie.  And, since many of the other public transit projects being planned are decades away from being completed, those numbers might not change much.  One other thing, Steve: less than 1 percent of all L.A. commuters bike to work, which would throw cold water on the idea that biking in L.A. is becoming a popular way of getting to the office.

Julian: People just prefer commuting by car…

Lacter: It remains the most convenient way of getting around - despite the congestion.  New car sales are up 14 percent through the first nine months of the year in Southern California.  Add to that are generally affordable gas prices (they've been especially low in the last few weeks).  In other parts of the world, congestion is considered a good thing because it means that the economy is doing well.  Which explains that while L.A. is the most congested city in the U.S., it doesn't rank among the 10 around the world.  On that front, Moscow is tops, followed by Istanbul, and Rio de Janeiro.

Julian: What about driverless cars?

Lacter: Well, these vehicles hold the most promise for reducing accidents, lowering travel times, and improving fuel economy - and you don't have to give up your car.  Actually, a lot of the technology is already in place - that includes stuff like radar-based cruise control, and devices that keep you at a safe distance from the car in front of you.  The trick, of course, is taking these individual capabilities and integrating them into an entirely driverless car.  Several car companies say they could be ready to start selling by 2020, with Google saying that its car could be ready even sooner.

Julian: Is that realistic?

Lacter: Who knows?  But even if the dates can be met - and that's a big if, considering how complex these systems are - legislatures will have to determine, among other things, whether vehicles can be fully autonomous (meaning that you can curl up and take a nap while the computer is driving by itself).  Or, whether they will only be semi-autonomous, which would be like an airline crew using automatic pilot, but always prepared to take over the controls.

Julian: Is that a liability issue?

Lacter: Yes - if something does go wrong, who will get the blame?  The owner of the vehicle?  The carmaker?  The suppliers of the car companies?  These questions might take years to get resolved in the courts - and even then, it could be years before the percentage of these vehicles on the road is large enough to truly have an impact.  But, considering that most commuters aren't willing to give up their cars, this would seem to be the most exciting, most desirable idea.  One day.

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.

An efficient synthesis of 1-aryl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazo­tization of 3-amino-4-aryl­amino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The mol­ecules of 1-phenyl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C—H⋯N and C—H⋯O hydrogen bonds, while the structures of 1-(2-methyl­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the mol­ecules into simple chains, which are further linked into sheets by π-stacking inter­actions in (II) but not in (III). In the structure of 1-(4-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the mol­ecules into sheets. When com­pound (II) was exposed to a strong acid in methanol, qu­anti­tative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hy­droxy-1-(2-methyl­phen­yl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the mol­ecules are linked by paired O—H⋯O hydrogen bonds to form centrosymmetric dimers.

An operationally simple and time-efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoeth­yl)-3-hy­droxy­indolin-2-ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkyl­isatins. These aldol products were used successfully as strategic inter­mediates for the preparation of N-substituted (E)-3-(2-hetaryl-2-oxo­ethyl­idene)indolin-2-ones by a stereoselective dehydration reaction under acidic conditions. The products have all been fully characterized by 1H and 13C NMR spectroscopy, by mass spectrometry and, for a representative selection, by crystal structure analysis. In each of (RS)-1-benzyl-3-hy­droxy-3-[2-(4-meth­oxy­phen­yl)-2-oxoeth­yl]indolin-2-one, C24H21NO4, (Ic), and (RS)-1-benzyl-3-{2-[4-(di­methyl­amino)­phen­yl]-2-oxoeth­yl}-3-hy­droxy­indolin-2-one, C25H24N2O3, (Id), inversion-related pairs of mol­ecules are linked by O—H⋯O hydrogen bonds to form R22(10) rings, which are further linked into chains of rings by a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds in (Ic) and by C—H⋯π(arene) hydrogen bonds in (Id). The mol­ecules of (RS)-1-benzyl-3-hy­droxy-3-[2-oxo-2-(pyridin-4-yl)eth­yl]indolin-2-one, C22H18N2O3, (Ie), are linked into a three-dimensional framework structure by a combination of O—H⋯N, C—H⋯O and C—H⋯π(arene) hydrogen bonds. (RS)-3-[2-(Benzo[d][1,3]dioxol-5-yl)-2-oxoeth­yl]-1-benzyl-3-hy­droxy­indolin-2-one, C24H19NO5, (If), crystallizes with Z' = 2 in the space group Poverline{1} and the mol­ecules are linked into com­plex sheets by a combination of O—H⋯O, C—H⋯O and C—H⋯π(arene) hydro­gen bonds. In each of (E)-1-benzyl-3-[2-(4-fluoro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H16FNO2, (IIa), and (E)-1-benzyl-3-[2-oxo-2-(thiophen-2-yl)ethylidene]indolin-2-one, C21H15NO2S, (IIg), the mol­ecules are linked into simple chains by a single C—H⋯O hydrogen bond, while those of (E)-1-benzyl-3-[2-oxo-2-(pyridin-4-yl)ethyl­idene]indolin-2-one, C22H16N2O2, (IIe), are linked by three C—H⋯O hydrogen bonds to form sheets which are further linked into a three-dimensional structure by C—H⋯π(arene) hydrogen bonds. There are no hydrogen bonds in the structures of either (E)-1-benzyl-3-[2-(4-meth­oxy­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C24H19NO3, (IIc), or (E)-1-benzyl-5-chloro-3-[2-(4-chloro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H15Cl2NO2, (IIh), but the mol­ecules of (IIh) are linked into chains of π-stacked dimers by a combination of C—Cl⋯π(arene) and aromatic π–π stacking inter­actions.

Jim Ross is the most famous pro wrestling play-by play commentator of all time. He's a native Californian, but grew up in Oklahoma and took his trademark drawl into doing commentary. He's worked in wrestling for more than 40 years, calling matches on shows seen by millions of people around the world.

This weekend, he's in the Bay Area for Wrestlemania weekend (the first Wrestlemania in Northern California, and the first in California in 10 years). Ross no longer commentates for WWE, but he's still a storyteller, online and in person. He hosts regular live storytelling shows with stories from his decades-long career and a bit of comedy, along with a live guest, and he also has a huge online presence including a podcast that went to number one in sports its first week out.

Ross has been watching wrestling since he was a kid.

"My dad wasn't a big fan of it. He missed the point. The point is not whether it's real or if it's staged. The point is, are you entertained by it, or not? And I was," Ross said.

He's been at ringside for numerous historic matches, helping the wrestlers to tell their stories ever since he got his first job in wrestling out of college at 22.

"The greater the star, the easier it is to tell their story," Ross said. "Those participants make music. They make different kinds of music, and the announcers, the broadcasters, have to be able to provide the adequate lyric to the competitors' music."

Ross's voice is so powerful that it's become a meme online to pair his voice with another dramatic footage, from sports and beyond — you can even find it paired with dramatic moments from shows like "Breaking Bad" and "Game of Thrones." Ross says that the first time he saw someone do that was with a hit by Michigan running back Jadaveon Clowney, a video which went viral and sparked others to do likewise.

The JR Treatment

"I get sent these memes all the time. 'Hey JR, check this one out.' Or people will say, somebody will make a great dunk at an NBA game, and somebody will say 'I can't wait to see this get the JR treatment.' And now there are major sports websites that will send out a tweet, 'Here's a great play from Sunday's 49er-Charger game that's got the JR treatment.' So now it's got a name. 'The JR Treatment.'"

Those viral videos have even helped him land new commentating roles since leaving WWE. He did a call of a fight between NASCAR drivers for the Daytona 500 for a special pre-show video, and it's led to him having opportunities in traditional sports.

"It's been done in boxing, and MMA. Believe it or not, I've gotten feelers that we're entertaining now from a variety of combat sports entities that actually heard what my call would sound like doing their product," Ross said. "It had my tone, had my inflection, had my level of enthusiasm."

Ross also played a huge role behind the scenes, working as WWE's executive vice president of talent and signing future stars like the Rock, Mick Foley and more. He says that Mick Foley's match against the Undertaker in 1998's Hell in a Cell match was his most memorable to call.

"I have people walk up to me and start quoting my commentary when Undertaker threw Foley off the Hell in a Cell, this massive cage with a roof on it, that was about 17 feet high from the roof to the floor," Ross said. "It looked like no human being, quite honestly, could survive that fall. You don't practice falls like that in wrestling school."

Ross has managed to stay relevant with the help of a popular podcast and 1.3 million followers on Twitter, where he regularly dispenses his thoughts on wrestling and beyond. He started doing that podcast after being lobbied to do it by "Stone Cold" Steve Austin, and continues to try new things.

"I was very reluctant to engage in social media, and primarily because we sometimes get set in our ways, especially the older we get," Ross said. "But change, for any of us, in any walk of life, whether it's your diet, it's your relationships, the way you approach your job, or any changes that you need to affect, whether it's on doctor's orders, your significant other's suggestions — change is not always a negative thing. So I got on Twitter, and then Twitter connected me to so many people."

While some may feel that pro wrestling, given its predetermined results, doesn't need real athletes, Ross disagrees and says there are plenty of reasons to want real athletes.

"They're competitive. They don't want to be on the second team. They want to be in the game. And they've been in that mindset since some of them were in little league, or Pop Warner football, or elementary school wrestling, or whatever it may be."

He says they also understand how to be coached and how to play well with others, as well as handling the bumps and bruises that come with the territory and the difficult travel schedule.

"I don't know that anybody in any entity, unless you're the most well-traveled comedian or entertainer, has that. Because the thing about pro wrestling is it doesn't have an off-season, so you don't get a chance to really go recharge your batteries. You've got to maintain that competitive edge to survive."

Ross says there's one match he wishes he had another shot at calling: Ric Flair's retirement match against Shawn Michaels at Wrestlemania 24 in Orlando at the Citrus Bowl. While Ross has traditionally been a play-by-play commentator, that night he was assigned to be a color commentator, which gave him some different challenges.

"I thought I had great stories to tell because of my relationship with Ric — I've known him for 25 years — and I didn't think that I contributed as much to that match from an emotional standpoint as I could. I was obligated to get in soundbites and get in, get out," Ross said. "That's the biggest match at the biggest stage, and I love both those guys, and I really wanted to be extra special that night, and I just don't know in my heart that we got there."

He says California has its own wrestling legacy to be proud of. The California Wrestlemania match that Ross says he'll always remember: Bret Hart versus Shawn Michaels at Wrestlemania 12 in Anaheim, where two now wrestling legends wrestled for more than an hour.

He also thinks the economics of Wrestlemania make a lot of sense for whichever city hosts it, thanks to the travelers it draws in from around the world. Cities now bid to try to bring in Wrestlemania, Ross says. With Los Angeles gearing up to build a new stadium, Ross has a Wrestlemania prediction for that stadium.

"I will bet you money — I will bet you some of my barbecue sauce — if L.A. builds a stadium, that Wrestlemania will be one of the first non-football events in that stadium. And they will sell it out. They'll fill every seat. And it'll be great for the city, and the businesses of Los Angeles.

Ross says that what made him a great broadcaster is the same thing that can make someone a success in wrestling or anywhere else — most importantly, don't talk down to your audience.

"You have to be a fan of the genre, or a fan of the game, and you have to be willing to prepare and be ready for your broadcast," Ross said. "You have to be willing to tell the story that the average fan — not the hardcore fan, but the average, casual fan can understand and relate to. ... You know, we're storytellers, and some people are just natural-born storytellers."

Ross plans to continue telling stories for the foreseeable future, on stage, online, calling matches in the legit sports world and wherever else his life takes him. He's even gotten into acting — you can see him in the new film "What Now."

"I think retirement is overblown. How many days can you go fishing? How many rounds of golf can you play?" Ross said. "I had the idea when I left WWE after 21 years, I'm going to reinvent myself. I'm not going to become a trivia answer. ... I don't think you're going to read anywhere, anytime soon, that Jim Ross has finally retired — until you read my eulogy."

Listen to the audio for the full hour-long interview with Jim Ross, talking his career past, present and future — along with the origins of his signature barbecue sauce.

For all the sad comic book and pop culture fans who weren't able to get tickets to San Diego Comic-Con, we've got good news for you: They run another convention, and it's closer to Los Angeles. Their little brother WonderCon Anaheim has been growing, with some comparing it to the Comic-Con of old — before it got way too crowded. It's this Friday through Sunday, April 3-5. They're starting to have big stars and lots of great panels, so if you want to get your geek heart sated, here are some of the events you won't want to miss.

Warner Bros. Presentation: San Andreas, Mad Max: Fury Road

San Andreas trailer

The most highly anticipated event at this weekend's convention, Warner Brothers is putting on a special presentation with footage from these two upcoming action films. They haven't announced which stars will be on hand, but these panels often surprise with star power, so you may get a visit from stars like "San Andreas's" Dwayne "The Rock" Johnson or "Mad Max: Fury Road's" Tom Hardy or Charlize Theron. At the Comic-Con panel last year for the "Mad Max" flick, the director talked in detail about the film, so you'll probably at least get his take on the franchise and its resurrection.

DC Comics TV shows: The Flash, Gotham, iZombie

The Flash trailer

While Marvel has been dominant on the big screen, DC has put out a diverse slate of TV shows, with "The Flash" being the biggest hit among them. It's among those getting a spotlight at WonderCon, with creators and stars dishing on the programs that have captured the imaginations of TV fans and comic fans alike. All three shows are also getting special video presentations, likely showing clips of what you can expect the rest of this season. And in case you didn't already know, "iZombie" comes from "Veronica Mars" creator Rob Thomas, so come find out about his latest project.

World Premiere: Batman vs. Robin

Batman vs. Robin trailer

It's become a tradition at both WonderCon and San Diego Comic-Con for DC Comics to debut their latest animated movie, and the new one is based on the critically acclaimed "Court of Owls" storyline by writer Scott Snyder. (Be sure to check out our previous interviews with Snyder — he's even an NPR fan.) The original story is based on how Batman thinks he knows everything there is to know about Gotham City and faces the discovery that there are deep secrets about the city that he had no idea about, and the film also emphasizes him fighting his son Damian.

Sing-alongs: Dr. Horrible & Batman's The Music Meister

Batman: The Brave and the Bold: Drives Us Bats

People go to comic conventions to geek out, and what's geekier than a good old-fashioned singalong? In addition to one for geek god Joss Whedon's much loved Web series "Dr. Horrible's Sing-Along Blog," they're also doing one for the musical episode of animated series "Batman: The Brave and the Bold" — which, just like "Dr. Horrible," features singing by the one and only Neil Patrick Harris. In the Batman cartoon, he plays the Music Meister, a Batman villain who makes both heroes and villains sing, as he drops some tunes of his own.

Superman: The Richard Donner Years Celebrity Super Reunion

Superman: The flying sequence

There's a reunion of stars from the first two of the classic Christopher Reeve Superman movies, including Lois Lane herself, Margot Kidder. You can also see the actors who played characters like Jimmy Olsen, several of the villains and more, as well as two of the producers. Find out what you don't know about the movie that broke ground when it came to depicting flight on-screen and, like the ads promised, made you believe a man could fly.

TV writing panels

Two panels will give you a peek into the world of the writers who write some of the hottest shows on TV: "TV Guide Magazine's Fan Favorites Showrunners" and "Inside The Writers' Room: Earth's Mightiest Writers Re-Assemble Redux." The first of those includes legendary TV showrunners like Dan Harmon of "Community" and the minds behind shows including "Orphan Black," "The Goldbergs" and more. Meanwhile, at the writers room panel, you'll get writers who've worked on shows like "Lost," "Firefly," "Heroes," "The Big Bang Theory," "Agent Carter" and more.

Fan culture programming track

This includes a lot of different panels, but it's a sign of the way fandom is shifting — it's a lifestyle that's far more diverse than it used to be, with a lot more gender parity. This track includes panels on topics like body confidence in cosplay, fashion, fitness, race and more. See what sparks your interest and might invite you into having an identity as a fan being a bigger part of your life while not letting anyone make you feel excluded.

There's so much more, like Will Forte doing a panel promoting his new show "The Last Man On Earth," the annual cosplay masquerade and so much more. Tickets are sold out for Saturday, but at press time, tickets were still available for both Friday and Sunday at WonderCon.

The United Teachers Los Angeles declared an impasse Wednesday in its talks with the Los Angeles Unified School District.

The action opens the way for a mediator to be brought in to help bring about a settlement.

Contract talks have been ongoing since July, UTLA said on its website.

"There is still a significant gap between the two sides on compensation," the union stated. UTLA is seeking an 8.5 percent, one-year increase; LAUSD has offered a 5 percent increase. 

The union said the district is "refusing to bargain in good faith on student learning conditions, and threatening educator layoffs as a scare tactic."

LAUSD Superintendent Ramon Cortines said in a statement that the district agrees the talks are at an impasse.

"I've been disappointed and frustrated by the lack of progress toward an agreement," he said. "It's my hope that the appointment of a mediator will lead to an expeditious settlement that ultimately supports our students and the District at large."

UTLA represents 31,000 members, including teachers and health and human service professionals.

The differences between the two sides amount to more than $800 million, the district said in its statement. Cortines has maintained that the district is facing a deficit. The union insists the district has money.

Other issues dividing the two sides include class room size and teacher evaluations.

As the city's March 3 primary election draws near, Los Angeles Unified school board candidates are blasting incumbents for the controversial iPad program.

Opponents sharply criticized the $1.3 billion bond-funded program at a debate Tuesday in West San Fernando Valley, where District 3 school board member Tamar Galatzan was elected in 2007.

"Galatzan said the district is going in the right direction," declared candidate Carl Petersen, a parent and businessman. "I don’t know how anyone can look at the events of the past year and come to that conclusion."

The program attracted national attention last December when the FBI raided district offices and carted off 20 boxes of bids, evaluations and correspondences with executives at Apple and its subcontractor Pearson, the manufacturer of the learning software loaded on to each device. The investigation is ongoing.

At the debate, teachers dressed in dark windbreakers with FBI plastered on the back in protest to Galatzan's support of the program. (They have not held similar demonstrations at election events in East Los Angeles' District 5, where Bennett Kayser, a teacher union ally, is running for re-election.)

Tom Richards, a Granada Hills parent, said he considers the iPad program a central issue as he weighs candidates.

"I think it's absolutely ridiculous," Richards said. "I don't believe that's a good way to spend the money that they have. Looking at some really fundamental needs — we don't have a librarian, but we want to give iPads?" 

Galatzan was an early advocate for more technology in the classroom; it was her goal even before the iPad was on the market.

"There is a whole world out there that can be accessed through technology, and we need to take advantage of that," Galatzan told KPCC.

Her advocacy of technology hasn't always been controversial. Galatzan points to her 2010 initiative to fund school computer labs with a settlement from Microsoft.

The school board's support of the iPad program varied the first year, but waned in August after KPCC published a series of emails showing district administrators had close ties with Pearson, calling into question whether the bidding process was fair. Problems with the rollout of the devices and the effectiveness of the software they contained also eroded support for the program.

Still, school board members unanimously approved more iPad purchases after the FBI investigation came to light. Superintendent Ramon Cortines said the tablets were necessary for new digital state tests scheduled this spring and offered to purchase them under a different contract with Apple to avoid complications involving the federal probe.

If the candidates' positions are a measure of support for the program, it's unpopular at best.  All of Galatzan's opponents are against it. 

When asked in a KPCC election survey conducted if he supported the iPad program, Scott Schmerelson, a retired administrator and District 3 contender, responded: "Not when you are paying for them from LAUSD Bond Money! The taxpayers generously supported the bond issue with the belief that the money would be used to repair and modernize our schools." 

Candidate Ankur Patel said in his answer to the survey, "I oppose the LAUSD’s iPad program. Throughout the program, important questions were not asked enough, and when they were, they were not answered properly."

Filiberto Gonzalez, another Galatzan challenger, said of the iPad project: "It was a mistake and ill-conceived from the very beginning. As was noted in the report by the U.S. Department of Education last month, the Common Core Technology Project (iPad program) lacked 'established metrics of success' and 'was difficult to show the impact of the investment.'

Elizabeth Badger Bartels is also running for the District 3 seat, but did not respond to the survey by deadline.

Los Angeles Unified's arts education leaders took steps to renew long-dormant community partnerships with arts organizations Wednesday, part of an effort to revitalize arts education in the nation’s second largest school district. 

At the Los Angeles Cathedral in downtown L.A., the district's new arts ed director, Rory Pullens, held his first meeting with community arts organizations. More than 100 people representing several dozen groups attended the event.

Pullens outlined the district's arts plans and how community partners can help boost the arts for students.

“Guess what," Pullens said, getting a round of applause with cheers of support from some of the attendees. "We're back."

Pullens lauded the district's recent announcement clearing the way for arts funding for low-income students, and pointed to new allocations this year that helped some of the district's schools purchase items like art supplies.

He also said the district is working on a school survey to create an arts equity index that will change the way the district allocates arts funds. The index would measure how well schools are providing arts instruction and arts access to students. Originally planned for release last year, the index is now expected next month.

But Pullens also painted a grim picture of the district’s current arts offerings. He said about a third of the district's middle schools currently offer little or no exposure to the arts. Some of the district’s students can go through both elementary and middle school without taking a single arts class, he said. Because of gaps in arts instruction, students who start learning an instrument in elementary school, for example, might not have classes to continue music study in their middle or high schools.

Pullens further talked about widespread budget problems, but took district leaders to task for failing to restore arts funding to the budget as the recession eased.

He said the arts education branch is still facing a deficit. Superintendent Ramon Cortines told reporters recently that the district as a whole is looking at a $160 million shortfall heading into the 2015-2016 school  year.

Despite the mixed funding news, for many in attendance, the meeting marked a positive shift in the district's arts strategy. Some groups currently serve as partners with the district, but the gathering was the first major effort in several years to reach out to organizations with the aim of restoring arts in the schools.

Jay McAdams, the executive director of 24th Street Theatre, said he remembered a few years back when the district emailed a cease-and-desist letter calling for an end to all arts partnership programs. He saw Wednesday's meeting as a major turnaround. 

"This is just a real breath of fresh air. There’s hope, there’s hope for first time in a long time for arts," he said.

Congestion charging in Stockholm has become more successful over time, according to a study by Swedish researchers. Although the total cost of a journey that enters the congestion charge zone has fallen in real terms since the charges were first introduced in 2006, there has consistently been around 29% less traffic within the zone, compared with levels in 2005.

National Science Foundation (NSF)-funded researchers from North Carolina State and Elon universities have developed a technique that allows them to remotely control the movement of soft robots, lock them into position for as long as needed and later reconfigure the robots into new shapes. The technique relies on light and magnetic fields. "By engineering the properties of the material, we can control the soft robot's movement remotely; we can get it to hold a given shape; we can then return the robot to its original shape or further modify its movement; and we can do this repeatedly. All of those things are valuable, in terms of this technology's utility in biomedical or aerospace applications," says Joe Tracy, a professor of materials science and engineering at NC State and corresponding author of a paper on the work. In experimental testing, the researchers demonstrated that the soft robots could be used to form "grabbers" for lifting and transporting objects. The soft robots could also be used as cantilevers or folded into "flowers" with petals that bend in different directions. "We are not limited to binary configurations, such as a grabber being either open or closed," says Jessica Liu, first author of the paper and a Ph.D. student at NC State. "We can control the light to ensure that a robot will hold its shape at any point."
