The crystal structures of caesium di­hydrogen arsenate(V) bis­[tri­hydrogen arsen­ate(V)], Cs(H2AsO4)(H3AsO4)2, ammonium di­hydrogen arsenate(V) tri­hydrogen arsenate(V), NH4(H2AsO4)(H3AsO4), and dilithium bis­(di­hydrogen phosphate), Li2(H2PO4)2, were solved from single-crystal X-ray diffraction data. NH4(H2AsO4)(H3AsO4), which was hydro­thermally synthesized (T = 493 K), is homeotypic with Rb(H2AsO4)(H3AsO4), while Cs(H2AsO4)(H3AsO4)2 crystallizes in a novel structure type and Li2(H2PO4)2 represents a new polymorph of this composition. The Cs and Li compounds grew at room temperature from highly acidic aqueous solutions. Li2(H2PO4)2 forms a three-dimensional (3D) framework of PO4 tetra­hedra sharing corners with Li2O6 dimers built of edge-sharing LiO4 groups, which is reinforced by hydrogen bonds. The two arsenate compounds are characterized by a 3D network of AsO4 groups that are connected solely via multiple strong hydrogen bonds. A statistical evaluation of the As—O bond lengths in singly, doubly and triply protonated AsO4 groups gave average values of 1.70 (2) Å for 199 As—OH bonds, 1.728 (19) Å for As—OH bonds in HAsO4 groups, 1.714 (12) Å for As—OH bonds in H2AsO4 groups and 1.694 (16) Å for As—OH bonds in H3AsO4 groups, and a grand mean value of 1.667 (18) Å for As—O bonds to nonprotonated O atoms.

The com­pound poly[2-hy­droxy-N-methyl­ethan-1-aminium [μ3-cyanido-κ3C:C:N-di-μ-cyanido-κ4C:N-dicuprate(I)]], {(C3H10NO)[Cu2(CN)3]}n or [meoenH]Cu2(CN)3, crystallizes in the tetra­gonal space group P43. The structure consists of a three-dimensional (3D) anionic CuICN network with noncoordinated protonated N-methyl­ethano­lamine cations providing charge neutrality. Pairs of cuprophilic Cu atoms are bridged by the C atoms of μ3-cyanide ligands, which link these units into a 43 spiral along the c axis. The spirals are linked together into a 3D anionic network by the two other cyanide groups. The cationic moieties are linked into their own 43 spiral via N—H⋯O and O—H⋯O hydrogen bonds, and the cations inter­act with the 3D network via an unusual pair of N—H⋯N hydrogen bonds to one of the μ2-cyanide groups. Thermogravimetric analysis indicates an initial loss of the base cation and one cyanide as HCN at temperatures in the range 130–250 °C to form CuCN. We show how loss of a specific cyanide group from the 3D CuCN structure could form the linear CuCN structure. Further heating leaves a residue of elemental copper, isolated as the oxide.

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:

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.

Marvel Comics held a press conference this week announcing details about "Secret Wars," a company-wide comic book crossover that they promise will change everything.

Promises of change in comics often don't amount to much, but here's why this one just might, with Marvel teasing that it will produce a whole new world for its characters.

"We see this as putting an endcap to decades of stories and starting a new era," said Marvel Editor-in-Chief Axel Alonso. "And when you see the scope of the event, you see what we're doing, what we're willing to do, this is a place where we're going to be bringing new pieces onto the board and taking old pieces off. You guys will be yelling and screaming, you'll be loving, hating, and in equal measure."

Reboot history

Rival DC Comics has always been quick to have stories designed to streamline their history, with the "Crisis on Infinite Earths" being the most famous one — a story that destroyed the DC Comics universe of the time, birthing a new timeline that gave us the versions of DC's heroes we know today. Several minor and major reboots followed, with the biggest since then being 2011's New 52 (and a tease of another one with this April's "Convergence").

Meanwhile, Marvel still refers back to stories from their early days, beginning with the first issue of "Marvel Comics" in 1939, and more so since the launch of "Fantastic Four" and the interlinked Marvel Universe in the 1960s, led by Stan Lee and Jack Kirby.

Marvel previously launched a line of comics meant to offer a fresh vision of the Marvel characters called Ultimate Comics, but now the worlds of those characters and the traditional Marvel universe are getting combined thanks to "Secret Wars."

"The Ultimate Universe, the Marvel Universe, they're going to smash together," said Alonso. "This is the Marvel Universe moving forward."

"We've never done anything like this, ever," said Marvel senior vice president and executive editor Tom Brevoort. "And what we're going to do to top it, I don't know. Hopefully that will be somebody else's problem."

The stories leading to "Secret Wars," and what is Battleworld?

The story that's been built up so far has to do with different universes colliding into each other — and in the first issue of "Secret Wars," the Marvel and Ultimate Earths collide, with the heroes of those worlds unable to stop it. What's left behind is what Marvel is calling "Battleworld," a patchwork planet with different parts of it inhabited by the characters from different famous Marvel crossovers of the past (you can see some of those past titles in the slideshow above).

Marvel released this video to help you visualize what exactly Battleworld is:

Battleworld video

See a map of Battleworld here, showing the different worlds made up of old storylines to be explored in "Secret Wars" (and click to enlarge):

Brevoort described Battleworld as "The little melting pot in which the new Marvel Universe will be created" after the Marvel and Ultimate versions of Earth are destroyed. He said that Battleworld is what Marvel is going to be "during, through and after" the beginning of "Secret Wars."

"Once you hit 'Secret Wars' 1, there is no Marvel Universe. There is no Ultimate Universe. All there is is Battleworld, and a whole lot of empty void," Brevoort said.

"Every single piece of this world is a building block for the Marvel Universe moving forward," Alonso said. "None of these stories are Elseworlds, or What Ifs, or alternative reality stories. They aren't set in the past or the future. They're not set in an alternate reality. They're set in the reality of the Marvel Universe."

It's also a story that uses an old name — the original "Secret Wars" involved an alien taking heroes from Earth and forcing them into battle for the fate of the universe. It remains unclear if the villain from that crossover will play a role here.

Why is Marvel rebooting?

Observers were quick to speculate on some of the behind-the-scenes reasons for the change. Combining the Ultimate Universe with the traditional Marvel Universe would let them incorporate the half-black, half-Latino Spider-Man from the Ultimate line that grabbed headlines a few years ago. It would let them do something different with characters like the X-Men and the Fantastic Four, who have been a flashpoint for controversy due to Fox retaining rights in perpetuity to any films based on those characters.

It also opens the door to a longtime comic book trope: Bringing back to life the dead.

"If we were to want to resurrect Gwen Stacy, this would be the place to do it, wouldn't it?" Alonso said.

What do creators and fans think about "Secret Wars"?

Speaking of the death of Gwen Stacy, the writer who pulled the trigger on killing her, Gerry Conway, tells Newsarama that he's on board.

"I think like with any idea, the execution will matter more than the idea itself. The idea of a reset is, by itself, not a bad idea," Conway said.

One who's less on board with it: longtime Spider-Man artist John Romita.

"My guess is new fans will be okay with it, and old fans will grumble," Romita told Newsarama. "I’m not a businessman, but I do know that comic companies, for almost 100 years now, do whatever they can for shock value. They grab attention. Personally, I hate all the goofy things they do. When I was there, I used to fight stuff like this. But you can’t stop them."

Current Marvel writers have been sworn to secrecy about what happens once "Secret Wars" is done:

Dan Slott tweet

The lack of certainty about what this all means has led fans to wildly speculate, as well as poke fun at what might happen:

Fan tweet 1

Fan tweet 2

It's a story that's been years in the making.

"Every single time we've done an event, we've always had to be mindful of 'Secret Wars,' and we've had to make decisions based on the fact that we knew that 'Secret Wars' was headed our way," Alonso said.

Brevoort said that Hickman proposed a version of "Secret Wars" years ago, but that vision has since become significantly larger.

"It sounds like typical Stan lee hyperbole — and there's nothing wrong with typical Stan Lee hyperbole — but it is difficult to imagine something that would be larger in scope, in scale, than what we are doing with 'Secret Wars,'" Brevoort said.

That father of the modern Marvel comics world, Stan Lee, tells Newsarama that the reboot is "probably good."

"Anything they do that’s unexpected and different usually captures the attention of the fans," Lee said. "It sounds intriguing to me."

Lee also tells Newsarama that if he were to do it all again, he'd do it basically the same, describing what he did as "the right way to go, and maybe sometimes, even the perfect way to go."

"I liked making the Fantastic Four superheroes without a secret identity. I liked the tragedy of Spider-Man’s origin, the ‘with great power, there must also come great responsibility.’ I thought it was the right way of doing things at the time. And I still like what I’ve done," Lee said. "I can’t think, off the top of my head, of anything I’d really want to change."

What does "Secret Wars" mean for fans?

More details are promised in the weeks to come, with a free preview issue being released on Free Comic Book Day, May 2. While fans wait, they may want to heed the wait-and-see approach advocated by Conway and famed "Thor" artist Walt Simonson.

"Maybe this is coming back out of my old geology days, but I try not to have instant reactions to things and say, ‘Oh my God! That’s terrible!’" Simonson told Newsarama. "My basic reaction is usually ‘let’s see the evidence in the field.’ Let’s come back in a year and see what we’ve got. That will tell the story.”

And for those who say that Marvel is ruining their childhood by messing with the history of their favorite characters, Conway tells Newsarama:

"I would say to them, no, your childhood is still your childhood. There’s a point to be made, and it’s a universal one: We have to see that there’s a difference between what people do today, and what they did yesterday. Yesterday still exists, those stories still exist. Now someone else is getting a chance at a new childhood. And that’s nice."

Do you want to track the Dodgers as the new season gets underway, but either don't have cable or are at work during the game? Maybe you want to keep an eye on the boys in blue but have an office job that gives you checks in black and white, and you want to keep your bleeding red for your favorite team from sending your bank account into the red as well. Or maybe you just aren’t going to have access to a TV at the time. Here are four ways to check the Dodgers out this season.

1. Track what’s happening with MLB.com’s free Gameday service

Want to see what’s going on as if the Dodgers game was a video game? You have to pay if you want to watch video (with alternate angles!) or listen to audio with Major League Baseball's MLB.tv service — but you can watch virtual avatars simulating the game with MLB Gameday for free. Just visit MLB.com/scores, then click on the Gameday button beneath the game you want to follow. Or, you can keep it more old school by tracking scores on the scores page — alongside video highlights.

2. Follow what’s going on on Twitter

Want to keep an eye on things but don’t want to stare at a streaming video feed? You can follow what’s happening with Twitter. The Dodgers themselves tweet highlights and results at @Dodgers, plus you can do a search for “Dodgers” or track what’s happening on various popular hashtags, including #Dodgers, #ThinkBlue and #ITFDB (It’s Time For Dodgers Baseball).

3. Listen to the radio, over the air or online

The official Dodgers radio broadcaster in L.A. is AM 570 L.A. Sports. As noted above, you can also pay to listen to audio from MLB.tv — but the service isn't available for local, "in-market" games, which are blacked out as part of their contracts with local broadcasters. The Dodgers broadcasts are also available in Spanish on 1020 AM KTNQ.

4. Stream ESPN on your computer, phone or tablet

ESPN lets you watch the opening day game and others throughout the season online... well, some of you, at least. Due to various cable company deals and other red tape, you have to already be a cable subscriber — sorry, cord cutters — but most major cable company subscribers can log in and stream the Dodgers online, or using ESPN's mobile apps available on iOS and Android. That also means you can find a friend who has cable, and team up with them to watch online — or just hang out at their place for the foreseeable future.

Many other Dodgers games throughout the season will be on SportsNet L.A., but you have to subscribe to Charter Spectrum, Time Warner, or Bright House in the L.A. area to get this channel. However, five of the games this season will be shown on KTLA, expanding your options for potentially checking the Dodgers out. You can find out more in the SportsNet L.A. FAQ.

How are you tracking the Dodgers? Let us know in the comments or by tweeting us at @KPCC.

A budget deficit is preventing the Los Angeles Unified School District from offering teachers more than a 5 percent raise, Superintendent Ramon Cortines said Friday.

"I want some resolution," Cortines told reporters, but he said the district is now projecting a shortfall of $160 million heading into the next school year.

United Teachers Los Angeles, the union representing 31,000 teachers, declared an impasse Thursday in the contract negotiations. The two sides have been bargaining since July.

The teachers haven't had a pay increase in eight years, and their salaries are below that of neighboring districts. 

"You are not going to recruit and retain the quality teachers you need," UTLA President Alex Caputo-Pearl told KPCC's AirTalk this week. The union is seeking an 8.5 percent raise as well as smaller class sizes, more counselors and nurses, and revised teacher evaluations.

Cortines said the district's pay raise offer of 5 percent, retroactive to July 2014, would help make salaries more competitive. But he said the projected deficit is why LAUSD can't afford more.

Projections for the deficit have changed over the months. Last October, it was $365 million; in January, $88 million; and this month, $160 million. 

Teachers union representatives said California schools are receiving more money this year than any time since the recession. Gov. Jerry Brown's Local Control Funding process, which gives local districts more resources for education, is projected to garner the district $240 million more next school year. 

Cortines said he hopes to reach an agreement and he cautioned against any walkout.

"You talk about a budget deficit? It will exacerbate the budget deficit, because parents have other options," Cortines said. "They can go to other schools, private, parochial schools, they can go to charter schools, etc."

Cortines said a mediator is being called into the talks to help resolve the impasse.

The superintendent also repeated his doubts that the district can currently afford to put a computer in the hands of every district student. The program, a key initiative of his predecessor, John Deasy, used bond funds to pay for iPads and other devices.

Cortines said a statement elaborating on his remarks to reporters that "as we are reviewing our lessons learned, there must be a balanced approach to spending bond dollars to buy technology when there are so many brick and mortar and other critical facility needs that must be met."

Los Angeles Unified school board candidate Ref Rodriguez collected $21,000 in campaign donations from employees of his charter school network, Partnerships to Uplift Communities, in his bid to unseat incumbent Bennett Kayser in East Los Angeles’ District 5.

Most striking, a handful of his workers – a janitor, maintenance worker, tutor — are donating at or near the contribution limit, $1,100.

The contributions are a measure of supporters' high hopes to unseat Kayser in favor of Rodriguez, a candidate friendly to charter schools.

Rodriguez, an charter school administrator at Partnerships to Uplift Communities, received most of his financial support from the California Charter School Association Advocates, which received donations from such wealthy donors as former New York Mayor Michael Bloomberg and philanthropist Eli Broad.

Kayser, a former teacher elected as a board member in 2011, collected his largest donations from labor unions, particularly the United Teachers Los Angeles. 

Most of the money working toward Kayser and Rodriguez's reelection are not funneled into their individual campaigns, but to independent expenditure committees which are not subject to the $1,100 contribution limit.

In her first foray into political giving, Luz Maria Lopez, an office worker, donated $1,000 donation to the Rodriguez campaign, twice the amount of Partnerships to Uplift Communities' CEO, Jacqueline Elliot.

“I really believe in Ref. My kids go to PUC schools,” said Lopez, who has been employed by PUC since it opened 15 years ago.  

The employee contributions weren't coerced and will not be reimbursed, Rodriguez said. Many of them can be traced back to a holiday break fundraiser at Rodriguez’s sister’s home in La Puente.

“I know for many of them this is a tremendous sacrifice,” he said. “It’s just been sort of an outpouring of folks belief in me and what we are trying to do for the city.”

Charter school groups major funders

Direct campaign donations from individual contributors, such as Rodriguez’ employees, make up 18 percent of the money spent in the LAUSD’s District 5 school board race. 

The biggest donor is charter school advocacy groups, such as the California Charter School Association Advocates.

Donations have also come from self-described education reform groups that support charter school expansion and firing teachers deemed ineffective, among other issues.

All told, the advocacy groups contributed more than $700,000 to activities in support of Rodriguez and working against Kayser.

On the other side, UTLA funneled $330,000 of members’ contributions to activities supporting Kayser and working against Rodriguez.

While UTLA has turned up its political spending in the board race to stay competitive, it is routinely outspent, said Oraiu Amoni, the union’s political director.

“We never are going to be able to match [reformers] dollar for dollar,” Amoni said. “So our biggest thing is making sure our members are educated, are engaged, are aware — and vote.”

So far, campaigns and committees have spent more than $2 million on the 13 Los Angeles Unified school board candidates, according to filings with the L.A. City Ethics Commission. The contributions have paid for mailing of glossy ads, phone banks, billboards, robocalls and commercials on Spanish-language radio. 

Total contributions are expected to increase in the few days remaining before the primary and swell again in any May runoff. 

Even in major races, aggressive campaigns fueled by growing contributions from special interest groups make it difficult for candidates not affiliated with interest groups to stay competitive.

Limitless independent expenditures are "playing a major role in smaller and local elections,” said Ryan Brinkerhoff, campaign manager for Andrew Thomas, the unaffiliated candidate in the District 5 race.

Thomas, a professor at Walden University, donated $51,000 to his campaign, making him his own biggest contributor. He’s also attracted sizable local support: about 70 percent of his campaign donations come from residents who live in District 5.

Thomas has received no contributions from political action committees or advocacy groups.

Can he win?

“I think so, but it’s getting harder and harder,” Brinkerhoff said. “The results of this election are going to be very telling.”

Outside contributors, local concerns

When public schools were created in the United States, local communities were given control over their governance. Outside money “undermines the relationship between community members and their local public institutions,” according to John Rogers, an education professor at UCLA. 

“It undermines their sense that they own those institutions, and those institutions are theirs to be shaped,” he said.

Without the funds from Broad, Bloomberg and other large donors, Rodriguez’s employees’ contributions would have made up more than 30 percent of his campaign support. Instead, it’s 4 percent.

Kayser has also received support from outside the district, including donations from the American Federation of Teachers and the California Teachers Association.

"The voters have an interest in open and transparent elections in which outside dollars don't have too large an influence," Rogers said.

Clarification: This article has been updated to make clear that the California Charter Schools Association does not support or advocate for teacher firing policies. Support for incumbent Kayser from outside the district has also been noted.

Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A National Science Foundation-funded study identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds. The study marks the first time a genetic link has been clearly established between the Toxoplasma strains in felid hosts and parasites causing fatal disease in marine wildlife. The study's results highlight how infectious agents like Toxoplasma can spread from cat feces on land to the sea, leading to detrimental impacts on marine wildlife.

The molecular mechanism used by many bacteria to kill neighboring cells has redundancy built into its genetic makeup, which could allow for the mechanism to be expressed in different environments, say researchers at Penn State and the University of Wisconsin-Madison. Their new study provides insights into the molecular mechanisms of competition among bacteria. "Many organisms, including humans, acquire bacteria from their environment," said Tim Miyashiro, a biochemist and molecular biologist at Penn State and the leader of the research team. "These bacteria can contribute to functions within the host organism, like how our gut bacteria help us digest food. We're interested in the interactions among bacteria cells, and between bacteria and their hosts, to better understand these mutually beneficial symbiotic relationships." Cells of the bioluminescent bacteria Vibrio fisheri take up residence in the light organ of newly hatched bobtail squid. At night, the bacteria produce a blue glow that researchers believe obscures a squid's silhouette and helps protect it from predators. The light organ has pockets, or crypts, in the squid's skin that provide nutrients and a safe environment for the bacteria. "When the squid hatches, it doesn't yet have any bacteria in its light organ," said Miyashiro. "But bacteria in the environment quickly colonize the squid's light organ." Some of these different bacteria strains can coexist, but others can't. "Microbial symbioses are essentially universal in animals, and are crucial to the health and development of both partners," says Irwin Forseth, a program director in the National Science Foundation's Division of Integrative Organismal Systems, which funded the research. "The results from this study highlight the role small genetic changes can play in microbe interactions. Increased understanding will allow us to better predict organisms' performance in changing environments."

A new study shows that graphene sheets can block the signals mosquitoes use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention. Researchers showed that multilayer graphene can provide a twofold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place. The findings suggest that clothing with a graphene lining could be an effective mosquito barrier.

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."

In a May 4 research note, H.C. Wainwright & Co. analyst Ed Arce reported that Arcturus Therapeutics Holdings Inc. (ARCT:NASDAQ) formed a partnership with Catalent Inc. (CTLT:NYSE), which "raises the profile of LUNAR-COV19 as a leading vaccine candidate."

Arce reviewed Catalent's contribution to the partnership. The global contract development and manufacturing organization is to manufacture Arcturus' messenger RNA (mRNA) LUNAR-COV19 for protection against SARS-CoV-2 to be used first for human clinical trials and potentially, eventually commercially.

As for timing, Arce noted, San Diego, Calif.-based Arcturus intends to transfer its vaccine technology to Catalent this month and expects Catalent to manufacture the first batches of LUNAR-COV19 by June 2020. "Critically, Arcturus continues to anticipate initiation of Phase 1 testing of LUNAR-COV19 in the summer of 2020," Arce highlighted.

Catalent is to produce the vaccine at its biomanufacturing facility in Madison, Wisc. "This facility utilizes Catalent's flex-suite, a current good manufacturing practice manufacturing suite, that can produce batches at multiple scales and support Arcturus' proprietary mRNA manufacturing process," explained Arce.

Obtaining the vaccine from one facility domestically versus multiple entities worldwide should result in several benefits, Arce continued. They include easy development and production, accelerated delivery and improved costs. Arcturus believes Catalent can produce millions of doses of LUNAR-COV19 mRNA in 2020 and, if need be, hundreds of millions of doses each year subsequently for use globally.

Arce pointed out that LUNAR-COV19 differentiates itself from other similar vaccine candidates in that the technology and delivery platform behind it deliver an "extraordinarily low dose (perhaps 2 micrograms)" in "a potential single shot."

H.C. Wainwright has a Buy rating and a $62 per share price target on Arcturus, the stock of which is currently trading at about $42.12 per share.

In late April, Metalla Royalty & Streaming acquired two royalties, one of which was a Gross Overriding Royalty (GOR) on NuLegacy Gold Corporation (NUG:TSX.V; NULGF:OTCQX) flagship Red Hill project, a Carlin-style deposit in Nevada's world-famous Cortez trend.

To be clear, this was a transaction between Metalla and a private company; no cash or other remuneration flowed to NuLegacy. However, this news is still exciting and thought provoking as it pertains to a potential (implied) valuation of Red Hill. So much so, that—CEO/director of Finance and Marketing—Albert Matter put out this press release highlighting it. {corporate presentation}

Metalla's news is applicable to NuLegacy for a number of reasons. Let me start by saying I know the Metalla team, I've written about the company several times (although not recently).

This is a smart, hard-working, market-savvy group, with global experience, integrity and expertise. When dealing in streams and royalties, it's all about industry connections, market knowledge and deal flow. Metalla has that and is up to its eyeballs in deal flow (deals it can make or pass on).

Takeaways on implied valuation of NuLegacy's Red Hill project?

That's why this news is so interesting. It represents a reliable, unbiased vote of confidence in NuLegacy's Red Hill project. I was able to track down the president, CEO and a director of Metalla, Mr. Brett Heath, to ask him about his team's view of NuLegacy, their management and technical teams, and the Red Hill project,

"The Red Hill project is very interesting due to its location & position within the Cortez trend of Nevada that hosts globally significant mines & projects, specifically Cortez Hills, Pipeline & Goldrush. Although many near-surface deposits have been discovered, several blind deposits similar to Goldrush have yet to be found.

"NuLegacy's Rift Anticline is a promising new drill target, a chance to discover a large, high-grade deposit. The close proximity of Red Hill to Goldrush heavily influenced our understanding of the geology at Red Hill. Specifically, it allowed us to better understand that the Rift Anticline has similar stratigraphy to Goldrush, and similar mineralization events nearby."

Investors, shareholders and analysts are trying to figure out what (if any) read-throughs there are in terms of the valuation of the Red Hill project.

From the press release:

"Valuing Gross Overriding Royalties ("GORs") is a complicated business made easier in this instance by the straightforward nature of the [transaction] …. prorating the US$4 million purchase price for the total of 2% GOR that was acquired…. values a 1% GOR in the Red Hill project at ~US$2 million."

What this valuation exercise boils down to is how does the value of a 1% GOR compare to a conventional working interest in the same project? GORs are highly case specific, so I will give a range of possibilities. Many factors make GORs unique, but a rule of thumb is that a 1% GOR equates to a 5% working interest.

However, due to the unknown terms of this particular GOR, let's assume that the 1% GOR is equal to between a 5% and 10% working interest. By extending the range higher than 5%, more conservative valuations for Red Hull are obtained. In the chart below one can see that the implied ~US$2 million paid for a 1% GOR equals C$2.8 million at the current exchange rate.

Therefore, Red Hill's indicative valuation could be viewed as C$28 million to C$56 million, or C$0.08 to C$0.15 per share. Currently, the stock's trading at C$0.07. The company has a cash balance of C$4.5 million. {see corporate presentation}. I believe the C$0.08 to C$0.15/share range is conservative because Metalla's purchase of the GOR had a built-in profit expectation. The true ascribed value of a 1% GOR on the Red Hill project might be higher than C$2.8 million.

A true vote of confidence in NuLegacy Gold

Perhaps more important than an implied (subjective) valuation of Red Hill are the following takeaways. First, Metalla not only likes Red Hill, it must also feel good about the long-term prospects for Nevada and the U.S. Metalla looks at hundreds of deals a year from all over the world. Management can, and does, invest in dozens of jurisdictions.

Yet, in April 2020, it chose the U.S., …. Nevada …. the Cortez Trend…. Second, it chose a project that's pre-maiden resource. Remember, Metalla has paid out ~C$2.8 million, but doesn't make a penny of that back unless it re-sells some or all of the GOR it acquired, or Red Hill reaches commercial production. Therefore, I argue that investing at this relatively early stage is a stamp of approval in the extensive work done to date at Red Hill.

That Metalla chose to deploy capital in a gold asset rather than a silver asset, despite the gold-silver ratio being near an all-time high (over 110 to 1) seems promising. Finally, it chose the U.S. at a time when the currencies of Mexico, Australia, Canada and others have weakened considerably vs. the U.S. dollar, making exploration cheaper in those countries. One must have conviction to choose Red Hill over dozens of public and private, pre-maiden resource, projects around the globe.

In the end, a good project in a great jurisdiction is only as prospective as its technical/management teams. NuLegacy has prudently advanced Red Hill in good times and bad. For most of NuLegacy's existence, the gold price traded between about $1,050 and $1,400/oz.

Gold price at $1,730/oz. is a game-changer….

Now gold is hovering around $1,730/oz after almost touching $1,800/oz in March. This is a game-changer for juniors like NuLegacy that have tremendous blue-sky potential, (look at neighboring mines and development projects, some of the best on the planet) but like most juniors, have limited funding to conduct aggressive drill programs in a strong gold price environment.

A savvy company betting on the Red Hill project is yet another indication that the time has come for precious metal players to become more active in M&A.

The day that Barrick commits its deep experience (and deep pockets!) to NuLegacy's Red Hill, all royalties held on that project would soar in value. Why? The timeline to potential production would be shortened, perhaps by years, (more drilling, less investor hand holding, perhaps skipping a PEA or a PFS). The scope of the project would become larger—more drilling across a wider footprint (a 108 sq. km land package).

The value of the royalties could double, triple, quadruple…. who knows? The share price at which NuLegacy gets taken out could also be meaningfully stronger. After all the company has been through, I don't think the Board would sell the company below C$0.30/share. At least not with the gold price at $1,730/oz (or higher). Readers are reminded that C$1.5 billon OceanaGold Corp. & giant natural resources fund Tocqueville own a combined 21.5% of the company.

Might there be a bidding war for NuLegacy?

In a best case example then, there could be multiple bidders for NuLegacy. This is not nearly as crazy as it sounds, especially if the gold price keeps going up, or if the next (fully funded) drill program hits the mark. If Barrick were to make a move, OceanaGold, Newmont, or even Tocqueville (they could hold out for higher price) might have something to say about it.

Those entities, and/or other mid-tiers/majors in Nevada or around the world would keep Barrick honest. Over the years NuLegacy has been in touch with several well-known names, but I never know who they're talking with at any given time. Make no mistake, Barrick is best positioned by virtue of having the most synergies with Red Hill, so it can afford to pay several more pennies per share if need be. That's how a share price of C$0.30+ becomes possible.

Bottom line, NuLegacy Gold (TSX-V: NUG) / (OTCQX: NULGF) is a high-risk exploration play, but I believe a good speculation. There's no better time to be buying high-risk exploration than when the prices of the metals being explored for are moving up.

As more attention is drawn to NuLegacy, its team, the undisputed safety of Nevada, the prolific nature of the Cortez Trend, etc., I think there's compelling relative and absolute value here that readers should consider investigating further.
