The specification of organs, tissues and cell types results from cell fate restrictions enacted by nuclear transcription factors under the control of conserved signaling pathways. The progenitor epithelium of the Drosophila compound eye, the eye imaginal disc, is a premier model for the study of such processes. Early in development, apposing cells of the eye disc are established as either retinal progenitors or support cells of the peripodial epithelium (PE), in a process whose genetic and mechanistic determinants are poorly understood. We have identified Protein Phosphatase 2A (PP2A), and specifically a STRIPAK-PP2A complex that includes the scaffolding and substrate-specificity components Cka, Strip and SLMAP, as a critical player in the retina-PE fate choice. We show that these factors suppress ectopic retina formation in the presumptive PE and do so via the Hippo signaling axis. STRIPAK-PP2A negatively regulates Hpo kinase, and consequently its substrate Wts, to release the transcriptional co-activator Yki into the nucleus. Thus, a modular higher-order PP2A complex refines the activity of this general phosphatase to act in a precise specification of cell fate.

Malignant cancer cells can invade extracellular matrix (ECM) through the formation of F-actin-rich subcellular structures termed invadopodia. ECM degradation at invadopodia is mediated by matrix metalloproteinases (MMPs), and recent findings indicate that membrane-anchored membrane type 1-matrix metalloproteinase (MT1-MMP) has a primary role in this process. Maintenance of an invasive phenotype is dependent on internalization of MT1-MMP from the plasma membrane and its recycling to sites of ECM remodeling. Internalization of MT1-MMP is dependent on its phosphorylation, and here we examine the role of β1 integrin-mediated signaling in this process. Activation of β1 integrin using the antibody P4G11 induced phosphorylation and internalization of MT1-MMP and resulted in increased cellular invasiveness and invadopodium formation in vitro. We also observed phosphorylation of Src and epidermal growth factor receptor (EGFR) and an increase in their association in response to β1 integrin activation, and determined that Src and EGFR promote phosphorylation of MT1-MMP on Thr⁵⁶⁷. These results suggest that MT1-MMP phosphorylation is regulated by a β1 integrin-Src-EGFR signaling pathway that promotes recycling of MT1-MMP to sites of invadopodia formation during cancer cell invasion.

Epithelial cells such as liver-resident hepatocytes rely heavily on the Rab family of small GTPases to perform membrane trafficking events that dictate cell physiology and metabolism. Not surprisingly, disruption of several Rabs can manifest in metabolic diseases or cancer. Rab32 is expressed in many secretory epithelial cells but its role in cellular metabolism is virtually unknown. In this study, we find that Rab32 associates with lysosomes and regulates proliferation and cell size of Hep3B hepatoma and HeLa cells. Specifically, we identify that Rab32 supports mTORC1 signaling under basal and amino acid stimulated conditions. Consistent with inhibited mTORC1, an increase in nuclear TFEB localization and lysosome biogenesis is also observed in Rab32-depleted cells. Finally, we find that Rab32 interacts with mTOR kinase and that loss of Rab32 reduces the association of mTOR and mTORC1 pathway proteins with lysosomes, suggesting that Rab32 regulates lysosomal mTOR trafficking. In summary, these findings suggest that Rab32 functions as a novel regulator of cellular metabolism through supporting mTORC1 signaling.

Optineurin (OPTN) is a multifunctional protein involved in autophagy, secretion as well as NF-B and IRF3 signalling and OPTN mutations are associated with several human diseases. Here we show that, in response to viral RNA, OPTN translocates to foci in the perinuclear region, where it negatively regulates NF-B and IRF3 signalling pathways and downstream pro-inflammatory cytokine secretion. These OPTN foci consist of a tight cluster of small membrane vesicles, which are positive for ATG9A. Disease mutations linked to POAG cause aberrant foci formation in the absence of stimuli, which correlates with the ability of OPTN to inhibit signalling. Using proximity labelling proteomics, we identify the LUBAC complex, CYLD and TBK1 as part of the OPTN interactome and show that these proteins are recruited to this OPTN-positive perinuclear compartment. Our work uncovers a crucial role for OPTN in dampening NF-B and IRF3 signalling through the sequestration of LUBAC and other positive regulators in this viral RNA-induced compartment leading to altered pro-inflammatory cytokine secretion.

Robert Kinoshita, the Los Angeles native who designed the iconic robots from "Lost in Space" and "Forbidden Planet," has passed away. He was 100 years old.

Konishita died Dec. 9 at a Torrance nursing home, according to the Hollywood Reporter, citing family friend Mike Clark. His creations included "Forbidden Planet's" Robby the Robot, the B9 robot from "Lost in Space," Tobor from "Tobor the Great" and more. Kinoshita also created "Lost in Space's" iconic flying-saucer-shaped Jupiter 2 spaceship.

Kinoshita built the original miniature prototype of Robby the Robot out of wood and plastic by combining several different concepts, according to the Reporter; the Rafu Shimpo reported that he struggled with the design.

"I thought, what the hell. We’re wasting so much time designing and drawing one sketch after another. I said to myself, I’m going to make a model," Kinoshita told the Rafu Shimpo in a 2004 interview. "Then one day, the art director sees the model. He says, ‘Give me that thing.’ He grabbed it and ran. ... Ten minutes later, he comes running back and puts the model back on my desk and says, ‘Draw it!’"

Watch Kinoshita and his colleagues talking about the construction of Robby the Robot:

Robby the Robot's construction

The 1956 classic sci-fi movie "Forbidden Planet" — based on Shakespeare's "The Tempest" — went on to be nominated for a special effects Oscar.

Kinoshita later served as art director on the 1960s sci-fi TV series "Lost in Space," creating the arm-flailing robot — named B9 — who delivered the classic line "Danger! Danger, Will Robinson!" That robot received as much fan mail as the actual humans on the show, according to the Reporter.

Watch the robot's feud with "Lost in Space's" Dr. Smith:

The robot vs. Dr. Smith

The "Lost in Space" robot even inspired a B9 Robot Builders Club, featured in Forbes. Kinoshita sent a message in 2000 to the club, thanking them for their support for the robot he originally nicknamed "Blinky."

"I'm truly flabbergasted and honored by your support for 'Blinky!' It's a well-designed little beauty," Kinoshita wrote. "Your thoughtful remembrance is something we designers seldom are lucky enough to receive."

Kinoshita described the thought process behind its design in a 1998 interview.

"You're laying in bed, and something comes to you," he said. "Until, finally, you get to a point where you say, 'This could work,' 'OK, let's see what the boss man says.' And you present it to him."

He told the Rafu Shimpo that he tried to create his robots to disguise the fact that there was a person inside. "I tried to camouflage it enough so you’d wonder where the hell the human was," he said.

Both the Japanese-American Kinoshita and his wife, Lillian, were sent to an Arizona internment camp during World War II, though they were able to get out before the end of the war and moved to Wisconsin, according to the Reporter.

While in Wisconsin, Kinoshita learned industrial design and plastic fabrication, designing washing machines for the Army and Air Force before returning to California, according to the Rafu Shimpo.

Kinoshita said that he had to overcome racial prejudice to break into working in Hollywood.

Kinoshita attributed his long life to clean living — along with daily doses of apple cider vinegar, family friend Clark told the Reporter.

Kinoshita also worked as a designer and art director on numerous classic TV shows, including "Kojak," "Barnaby Jones," "Hawaii Five-O," "Bat Masterson," "Sea Hunt," "Tombstone Territory," "Star Trek" creator Gene Roddenberry's "Planet Earth" and more, according to his IMDB. His last TV show was 1984's "Cover Up."

Kinoshita grew up in Boyle Heights, according to the Reporter, attending Maryknoll Japanese Catholic School, Roosevelt High School and USC's School of Architecture. His career began with work on 1937's "100 Men and a Girl." Kinoshita graduated cum laude from USC, according to the Rafu Shimpo.

Watch Kinoshita speak at his 95th birthday gathering with the B9 Robot Builders Club. He said he hoped to make it to 100, and he ended up doing so.

Bridges make travel faster and more convenient, but, in an earthquake, these structures are subject to forces that can cause extensive damage and make them unsafe. Now civil and environmental engineer Petros Sideris of Texas A&M University is leading a National Science Foundation (NSF)-funded research project to investigate the performance of hybrid sliding-rocking (HSR) columns. HSR columns provide the same support as conventional bridge infrastructure columns but are more earthquake-resistant. HSR columns are a series of individual concrete segments held together by steel cables that allow for controlled sliding and rocking. This allows the columns to shift without damage, while post-tensioning strands ensure that at the end of an earthquake the columns are pushed back to their original position. Conventional bridges are cast-in-place monolithic concrete elements that are strong but inflexible. Structural damage in these bridge columns, typically caused by a natural disaster, often forces a bridge to close until repairs are completed. But bridges with HSR columns can withstand large earthquakes with minimal damage and require minor repairs, likely without bridge closures. Such infrastructure helps with post-disaster response and recovery and can save thousands in taxpayer dollars. In an earthquake, HSR columns provide "multiple advantages to the public," Sideris said. "By preventing bridge damage, we can maintain access to affected areas immediately after an event for response teams to be easily deployed, and help affected communities recover faster. In mitigating losses related to post-event bridge repairs and bridge closures, more funds can be potentially directed to supporting the recovery of the affected communities." According to Joy Pauschke, NSF program director for natural hazards engineering, "NSF invests in fundamental engineering research so that, in the future, the nation's infrastructure can be more resilient to earthquakes, hurricanes, and other forces of nature."

On Thursday afternoon, dozens of employees of the publishing imprints Grand Central Publishing and Little, Brown staged a walkout to protest Grand Central's decision to publish Woody Allen's memoir, Apropos of Nothing, next month.

Both imprints are owned by Hachette Book Group (HBG), the same house that published journalist Ronan Farrow's Catch and Kill. The walkout comes after Farrow announced on Tuesday that he felt he could no longer work with HBG after the Allen acquisition.

Farrow is Allen's son with actress Mia Farrow; his sister, Dylan Farrow, has accused Allen of having sexually abused her as a child. Allen has long denied her allegations.

In his statement, Farrow wrote in part that HBG "concealed the decision from me and its own employees while we were working on Catch and Kill — a book about how powerful men, including Woody Allen, avoid accountability for sexual abuse."

Dylan Farrow also released a statement on Monday evening, in which she said in part: "Hachette's publishing of Woody Allen's memoir is deeply upsetting to me personally and an utter betrayal of my brother whose brave reporting, capitalized on by Hachette, gave voice to numerous survivors of sexual assault by powerful men. ... This provides yet another example of the profound privilege that power, money and notoriety affords. Hachette's complicity in this should be called out for what it is and they should have to answer for it."

Employees at both HBG's New York and Boston offices participated in the Thursday walkout. Many also sent out an auto-reply email that read in part: "We stand in solidarity with Ronan Farrow, Dylan Farrow and survivors of sexual assault." Those include Little, Brown executive editor Vanessa Mobley, who was the editor of Catch and Kill.

In a statement sent to NPR Thursday afternoon, HBG CEO Michael Pietsch said: "We respect and understand the perspective of our employees who have decided to express their concern over the publication of this book. We will engage our staff in a fuller discussion about this at the earliest opportunity."

NPR reached out for comment to Allen's agent, who did not respond as of publication time.

The New York Post reported that HBG employees approached the company's human resources department on Thursday afternoon to complain about the planned publication of Allen's book. A Hachette employee told NPR that HBG's CEO, Michael Pietch, attempted to hold a town hall meeting on Thursday to discuss the issue, but the employees walked out before the meeting was held.

Farrow's agent, Lynn Nesbit, told NPR on Thursday, "I feel moved almost to tears by the walkout. It was such a brave gesture to management who, in my opinion, made such a misguided decision." Signing Allen, she said, was "a betrayal of Ronan, of the women in his book, of the issues in the book and of the staff of this publisher." She added that Farrow is "grateful for the support of his colleagues at Little, Brown."

Last year, The New York Times reported that Allen had tried to sell the memoir to several major publishing houses, "only to be met with indifference or hard passes"; one source told NPR on Thursday afternoon that the title had been considered "radioactive" in the publishing world.

Farrow also said in his Tuesday statement that HBG had not fact-checked Allen's memoir, nor did it contact Dylan Farrow for any response. "It also shows a lack of ethics and compassion for victims of sexual abuse, regardless of any personal connection or breach of trust here. ... I've also told Hachette that a publisher that would conduct itself in this way is one I can't work with in good conscience."

As of Monday afternoon, L.A. County has at least 1,260 deaths and 26,238 confirmed cases of coronavirus. The United States has more than a million cases of the virus with more than 67,000 deaths. Meanwhile, new models put together by FEMA project that we could see up to 200,000 new cases a day by the end of the month, according to the New York Times. 

The L.A. Times reports that scientists have discovered a new strain of the deadly coronavirus that is even more contagious. The study finds that the new strain first appeared in February in Europe and has been the dominant strain across the world since mid-March. Plus, some COVID-19 patients are experiencing issues with blood clotting even after respiratory issues have died down.

After nearly two months of “safer at home” during the COVID-19 outbreak, the state of California appears to be taking its first steps towards reopening businesses and restarting the economy.

Governor Gavin Newsom announced on Monday during the daily press briefing he has held since the start of the outbreak that California will be entering the first phase of its four-stage plan and allowing certain retail businesses like bookstores, music stores, sporting goods stores and florists to reopen for pickup as early as Friday. Manufacturing and logistics can start in the retail supply chain again as well. There are also local control measures in effect that allow certain municipalities to decide themselves whether to move farther ahead in the process and reopen certain things like restaurant dining rooms, though anyone deciding to do so would have to submit “containment plans” to the state. Two cities in Orange County, which has been involved in a back-and-forth with Sacramento over his order last week closing all state and local beaches in OC, have been cleared to reopen their beaches after they submitted plans to the state last week for how they’d reopen the beaches while safely controlling crowds.

Renovating coastal structures, such as breakwaters, groynes, artificial reefs, quays and sea walls, can be destructive to Marine and Coastal as it encourages opportunistic and invasive species, according to recent research. Repairs can be particularly damaging if conducted in spring or summer, so repair schedules should be recognised in marine planning strategies to minimise negative ecological effects, say the researchers.

Amid all the talk about cutting-edge technology, much of Uber and Lyft’s success actually owes to that fact the ride-sharing companies have been able to exploit a basic loophole: The companies foist the cost of insurance on their drivers, but the drivers' insurance companies don’t know they are underwriting cars for hire, and even if drivers wanted to be honest and get a policy that would cover ride-sharing, they couldn’t, because no such policy exists.

AB-2293, introduced by Assemblywoman Susan Bonilla (D-Concord) and signed into law Wednesday by Governor Jerry Brown, tries to close the loophole by paving the way for insurance companies to offer hybrid personal/commercial policies by next summer.

Uber once derided the bill as a backroom deal between insurance companies and trial lawyers.

"The bill does nothing to enhance safety, yet compromises the transportation choices and entrepreneurial opportunities Uber offers Californians," the company wrote in a June blog post that encouraged customers to contact their representatives opposing the bill.

However, the company backed down and supported the legislation when Bonilla insurance requirements were lowered.

AB 2293 also specifically bans drivers from using their personal policies and mandates drivers have to be covered from the moment they turn on their app and look for customers, which is a response to the tragic accident on New Year's Eve in San Francisco when an UberX driver hit and killed a six year old child.

Uber argued that because the driver was waiting for a fare he wasn't working for the company at the time, so he wasn't covered by the company's insurance.

California Jerry Brown will sign a bill to expand California's film and television tax credit program into law in Hollywood; Credit: Justin Sullivan/Getty Images

A moment Hollywood's been waiting a while for will take place... in Hollywood. 

A ceremony is planned for Thursday morning at the Chinese Theater where Governor Jerry Brown will sign the "California Film and Television Job Retention and Promotion Act" into law.

The bill - also known  as AB 1839 — will more than triple the funding for California's film and television production tax credit program. 

The push to expand and enhance the tax credit program has been going on for more than a year. In August of 2013, Los Angeles Mayor Eric Garcetti used the term "state of emergency" to characterize the flight of film and television production to other states and countries. Garcetti is expected to speak at the ceremony. 

Los Angeles-area Assemblymen Mike Gatto and Raul Bocanegra are also expected to be on hand. They introduced AB 1839 in February and moved it strategically through the legislature in Sacramento. While there were few vocal opponents of expanding the tax credit program, the big question was by how much. Many supporters hoped to see the annual pot raised from the current $100 million to at least $400 million, but an exact dollar amount wasn't specified until very late in the legislative process.

In April, the state Legislative Analyst's Office released its hard look at the current tax credit program, pointing out that the state is only getting back 65 cents in tax revenues for every dollar it’s spending on the film and TV subsidy.  The bill to expand the program kept moving.

California's magic number turned out to be $330 million dollars, not as high as chief rival New York State's $420 million per year, but still more than triple California's current offering. Along with the extra cash, AB 1839 also changes the way the tax credit program will be administered.   Rather than using a one-day lottery to determine which productions receive the credit, the state will measure the projects based on their potential to create jobs.   A project that overestimates that potential could be penalized.

Gov. Jerry Brown has headed to the cradle of the Hollywood film industry to sign legislation that more than triples the state's annual tax credit to $330 million a year for films and TV shows produced in California.

Brown says the increase is needed to help prevent other states and countries from hijacking film and TV production by offering their own lucrative incentives.

Brown signed the bill Thursday at the former Grauman's Chinese Theatre, where handprints and footprints of stars from the eras of Humphrey Bogart to Robert De Niro are embedded in concrete.

Under the new system, credit will be awarded based on the number of jobs a production creates and its overall positive impact on the state.

The historic cinema is now called the TCL Chinese Theatre IMAX.

NFL Commissioner Roger Goodell talks during a press conference at the Hilton Hotel on Sept. 19, 2014 in New York City. Goodell spoke about the NFL's failure to address domestic violence, sexual assault and drug abuse in the league.; Credit: Elsa/Getty Images

Update 1:04 p.m. Goodell: 'Same mistakes can never be repeated'

Commissioner Roger Goodell says the NFL wants to implement new personal conduct policies by the Super Bowl. At a news conference Friday, Goodell made his first public statements in more than a week about the rash of NFL players involved in domestic violence. He did not announce any specific changes, but said he has not considered resigning.

"Unfortunately, over the past several weeks, we have seen all too much of the NFL doing wrong," he said. "That starts with me."

The league has faced increasing criticism that it has not acted quickly or emphatically enough concerning the domestic abuse cases.

The commissioner reiterated that he botched the handling of the Ray Rice case.

"The same mistakes can never be repeated," he said.

Goodell now oversees all personal conduct cases, deciding guilt and penalties.

He said he believes he has the support of the NFL's owners, his bosses.

"That has been clear to me," he said.

The Indianapolis Colts' Darius Butler was among those who tweeted criticism of the press conference:

Colts tweet 1

Colts tweet 2

The commissioner and some NFL teams have been heavily criticized for lenient or delayed punishment of Rice, Adrian Peterson and other players involved in recent domestic violence cases. Less than three weeks into the season, five such cases have made headlines, the others involving Greg Hardy, Ray McDonald and Jonathan Dwyer.

Vikings star running back Peterson, Carolina defensive end Hardy and Arizona running back Dwyer are on a special commissioner's exemption list and are being paid while they go through the legal process. McDonald, a defensive end for San Francisco, continues to practice and play while being investigated on suspicion of domestic violence.

As these cases have come to light, such groups as the National Organization of Women and league partners and sponsors have come down hard on the NFL to be more responsive in dealing with them. Congress also is watching to see how the NFL reacts.

In response to the criticism, the NFL announced it is partnering with a domestic violence hotline and a sexual violence resource center.

Goodell also said in a memo to the clubs late Thursday that within the next 30 days, all NFL and team personnel will participate in education sessions on domestic violence and sexual assault. The memo said the league will work with the union in providing the "information and tools to understand and recognize domestic violence and sexual assault."

The league will provide financial, operational and promotional support to the National Domestic Violence Hotline and the National Sexual Violence Resource Center.

12:07 p.m. Roger Goodell to break silence on domestic abuse and the NFL

Roger Goodell will make his first public statements in more than a week about the rash of NFL players involved in domestic violence when he holds a news conference Friday.

The NFL commissioner will address the league's personal conduct policy. The league has faced increasing criticism it has not acted quickly or emphatically enough concerning the domestic abuse cases.

His last public appearance was at a high school in North Carolina on Sept. 10.

The league will provide financial, operational and promotional support to the National Domestic Violence Hotline and the National Sexual Violence Resource Center.

"These commitments will enable both the hotline and NSVRC to help more people affected by domestic violence and sexual assault," Goodell said in the memo.

The National Domestic Violence Hotline provides domestic violence victims and survivors access to a national network of resources and shelters. It is available 24 hours a day, seven days a week in 170 languages. Goodell noted that the hotline received 84 percent more calls from Sept. 8-15, and the organization said more than 50 percent of those calls went unanswered because of lack of staff.

"The hotline will add 25 full-time advocates over the next few weeks that will result in an additional 750 calls a day being answered," he said.

NSVRC supports sexual violence coalitions across the United States. The NFL's initial support will be directed toward state coalitions to provide additional resources to sexual assault hotlines.

This allows the columns to shift without damage, while post-tensioning strands ensure that at the end of an earthquake the columns are pushed back to their original position. Conventional bridges are cast-in-place monolithic concrete elements that are strong but inflexible. Structural damage in these bridge columns, typically caused by a natural disaster, often forces a bridge to close until repairs are completed. But bridges with HSR columns can withstand large earthquakes with minimal damage and require minor repairs, likely without bridge closures. Such infrastructure helps with post-disaster response and recovery and can save thousands in taxpayer dollars. In an earthquake, HSR columns provide "multiple advantages to the public," Sideris said. "By preventing bridge damage, we can maintain access to affected areas immediately after an event for response teams to be easily deployed, and help affected communities recover faster. In mitigating losses related to post-event bridge repairs and bridge closures, more funds can be potentially directed to supporting the recovery of the affected communities." According to Joy Pauschke, NSF program director for natural hazards engineering, "NSF invests in fundamental engineering research so that, in the future, the nation's infrastructure can be more resilient to earthquakes, hurricanes, and other forces of nature."

Global air quality will significantly deteriorate by 2050 unless further steps are taken to cut current emissions from human activities, according to recent research. Most people around the world will be affected by worsening air quality with hotspots of particularly poor air occurring in China, northern India and the Middle East.

The last two decades have seen a series of new construction waste policies management in Hong Kong. One of the most significant is an offsite construction waste sorting (CWS) programme which, since its implementation in 2006, has separated 5.11 million tonnes of construction waste into different materials. The researchers suggest that the study provides an important reference for other countries working to minimise construction waste.

A recent study has described a simple method to screen the toxicity of materials used in consumer products. Using utility meter products as examples, the study found, for example, that stainless steel and polyvinyl chloride (PVC) had high toxicity potentials and suggests less toxic, but equally effective and priced, alternatives that could be used instead.

Researchers have developed a method to identify the parts that contribute the most to a product's greenhouse gas (GHG) emissions and evaluate alternative design solutions. When applied to a LCD television, it showed that GHG emissions could be cut by 36 per cent by using alternative parts to those currently used.

The qualities of sustainable design and the obstacles that Design for Sustainability (DfS) faces are explored by a new study which provides recommendations on how to overcome these challenges. It suggests that design education needs to change and provides advice on how to improve our understanding of consumer behaviour.
