A portable on-axis laser-heating system for near-90° X-ray spectroscopy: application to ferropericlase and iron silicide

A portable IR fiber laser-heating system, optimized for X-ray emission spectroscopy (XES) and nuclear inelastic scattering (NIS) spectroscopy with signal collection through the radial opening of diamond anvil cells near 90°with respect to the incident X-ray beam, is presented. The system offers double-sided on-axis heating by a single laser source and zero attenuation of incoming X-rays other than by the high-pressure environment. A description of the system, which has been tested for pressures above 100 GPa and temperatures up to 3000 K, is given. The XES spectra of laser-heated Mg0.67Fe0.33O demonstrate the potential to map the iron spin state in the pressure–temperature range of the Earth's lower mantle, and the NIS spectra of laser-heated FeSi give access to the sound velocity of this candidate of a phase inside the Earth's core. This portable system represents one of the few bridges across the gap between laser heating and high-resolution X-ray spectroscopies with signal collection near 90°.

Versatile compact heater design for in situ nano-tomography by transmission X-ray microscopy

A versatile, compact heater designed at National Synchrotron Light Source-II for in situ X-ray nano-imaging in a full-field transmission X-ray microscope is presented. Heater design for nano-imaging is challenging, combining tight spatial constraints with stringent design requirements for the temperature range and stability. Finite-element modeling and analytical calculations were used to determine the heater design parameters. Performance tests demonstrated reliable and stable performance, including maintaining the exterior casing close to room temperature while the heater is operating at above 1100°C, a homogenous heating zone and small temperature fluctuations. Two scientific experiments are presented to demonstrate the heater capabilities: (i) in situ 3D nano-tomography including a study of metal dealloying in a liquid molten salt extreme environment, and (ii) a study of pore formation in icosahedral quasicrystals. The progression of structural changes in both studies were clearly resolved in 3D, showing that the new heater enables powerful capabilities to directly visualize and quantify 3D morphological evolution of materials under real conditions by X-ray nano-imaging at elevated temperature during synthesis, fabrication and operation processes. This heater design concept can be applied to other applications where a precise, compact heater design is required.

'Ready Player One' was written using cheat codes — here are our 11 favorites

A Nintendo Entertainment System.; Credit: Mark Ramsay/Flickr Creative Commons

Mike Roe

There have been plenty of video game movies over the years, but there have been far fewer actually good ones. "Ready Player One," based on the 2011 video game-inspired novel, has the chance to be a great one thanks to the announcement that Steven Spielberg has signed on to direct.

That book was inspired by classic video games, and was written using classic video game cheats to play parts of classic games and write them into his book, author Ernest Cline said in a recent talk. That got us thinking about the classic video game cheats and secrets that stuck with us from our younger days playing classic video games — here's our top 11.

1. The Konami Code

Up up down down left right left right B A start! This code became such a part of video game culture that it got its own name. It was popularized in various games made by Konami, particularly Contra, leading to it also being known as the "Contra Code" for its ability to give you 30 lives in the game. Before the Internet, it was spread through gaming magazines and word of mouth — it was so influential that there are still developers who put it in their games. (There's even an entire Wikipedia page of games, both from Konami and others, that use the Konami Code. It's even been used on some websites.)

What is the Konami Code

2. Street Figher II Turbo's turbo

The game that I actually used a code for the most as a kid, the Super Nintendo code down, R, up, L, Y, B on the second controller didn't give you any advantages — it just kicked the speed up. By default, you had a few selections for how fast the game would be, but you could multiple that several-fold with this code, letting you and your friends battle at what at the time felt unbelievably fast.

3. Super Mario Bros.'s Minus World

This one doesn't involve a code, but players managed to discover what was deemed a glitch in the game that put you into a messed up version of another level, dubbed by fans the Minus World due to just "-1" instead of a full level number appearing at the top of the screen. There was no way to escape the glitched level, no matter how hard you might try, sending you to play it over and over again until your time ran out or you were killed by enemies. Still, modern players have found that you can go on thanks to various computer emulators and the like; see some of the worlds beyond below:

Minus World video

4. Metroid and Justin Bailey

Fans early on discovered that the password JUSTIN BAILEY allowed you to start with all of the available weapons along with plenty of life and ammo. Fans didn't know whether Justin Bailey was a reference to an actual person, just a code coincidence or something else, but that didn't stop them from eagerly playing through with this code. It also removed lead character Samus Aran from her armor, allowing players to discover that the game's star was an early female lead character, even if her armor didn't clue players in before the end of the game without the code.

Justin Bailey video

5. Doom's God mode

By typing the letters iddqd in PC game Doom, players could enable God mode, making them essentially invincible and letting them power through the early first-person shooter. The code had been available in developer id's earlier game Wolfenstein, but hadn't been quite as easily accessible. So, if you ever need a power boost when you're fighting on Mars, Doom has the answer. (Unfortunately, we don't believe this provides any extra protection for NASA's Mars rovers.)

6. Mortal Kombat's Reptile

The developers of Mortal Kombat made a battle against Reptile unbelievably hard for Mortal Kombat fans, including putting some randomness into whether doing what you were supposed to do to unlock the character would even work. Still, players happily pumped in extra quarters for the chance to face off against Reptile, a character with a look that mirrored that of characters Sub-Zero and Scorpion, just with a different color. Players had to achieve a Double Flawless victory on the Pit level, finish the match using their fatality move, and there also had to be a silhouette flying past the moon in the background — which only happened every sixth game.

Mortal Kombat: Reptile

7. The Legend of Zelda's Second Quest

The Legend of Zelda was a pretty challenging early adventure game, one of the first releases for the Nintendo home video game console. When you beat the game, you were given the option to go on a "Second Quest," which was a tweaked version of the game you just played except waaaaay harder. However, if you thought you were the coolest kid on the block and were so awesome you didn't need a warmup, you could name your character "ZELDA" (in one of the more obvious cheats in video game history) and skip ahead to that Second Quest from the start. You would then likely cry from how hard it was and start another new game with a different name.

8. NBA Jam's celebrity secret characters

A variety of celebrities from sports, music, and even politics were available by putting in various initials combined with buttons on the controller. These included then-President Bill Clinton, Al Gore, Warren Moon and more. That tradition has been continued in more recent NBA Jam games, with President Obama and others available for your video gaming pleasure.

9. GoldenEye's extra modes

There were a wide variety of cheat codes for GoldenEye, widely considered one of the all-time great first-person shooters. Sure, you could use codes to unlock different levels, but the reason these codes are remembered is because it gave you all sorts of new ways to play against your friends. The game also had an actual cheat menu that would appear if you accomplished one of a variety of goals, and from that menu you could cheat extra hard by using your controller to unlock things like a paintball mode, turbo mode, modes with both giant heads and teeny-tiny James Bonds and more.

10. Sonic The Hedgehog 2's Debug Mode

The Sonic debug mode is the perfect example of why so many games included cheats back in the day: They were often for the developers to be able to more easily play the games while looking for bugs and doing other testing. Sonic 2 let you get to an actual debug mode by playing various sounds from the level select screen (1, 9, 9, 2, 1, 1, 2, 4, for your reference), then pressing start and holding the A button. Developers later put them in for fun and intended them for the players to discover, but some of the early cheat codes were just meant for developers — but players proved more intrepid than they may have anticipated.

Sonic debug mode

11. Mike Tyson's Punch-Out: Go straight to Mike Tyson

There was actually a password mode in this game — before games had the option to save, plenty of games gave you codes that let you get back to where you were before. This is one of the examples from that darker time, where whether you played through opponents like Glass Joe and Bald Bull or not, you could try your changes against Lightning Mike (at least until the video game's license ran out and he was replaced in future editions with the way less exciting "Mr. Dream"). You better have had a pen and paper ready when your friend started yelling at you 007 373 5963 for you to use on your own copy of the game — no sharing. The game is hard enough that even Mike Tyson had some trouble fighting himself:

Mike Tyson vs. Mike Tyson

Let us know in the comments the classic video games — and the classic cheat codes and secrets — that inspired you.

Wil Wheaton and other Star Trek alumni perform in 'War of the Worlds' benefit

John Rabe

There are still a couple dozen tickets left for one of the most interestingly-cast performances of H.G. Wells, Orson Welles and Howard Koch's "War of the Worlds." On Saturday, Jan. 17,  generations of Star Trek actors will take on the world's most famous radio show.

The cast — directed by Jim Fall — features: René Auberjonois (“Star Trek: Deep Space Nine”), Michael Dorn (“Star Trek: TNG”), Dean Haglund (“The X-Files”), Walter Koenig ("Star Trek"), Linda Park ("Star Trek: Enterprise"), Jason Ritter (“The Event”), Tim Russ (“Star Trek: Voyager”), Armin Shimerman (“Star Trek: Deep Space Nine”) and Wil Wheaton, playing... Orson Welles.

The performance is a fundraiser for Sci-Fest LA, the new annual science fiction play festival, so tickets aren't cheap — but they're scarce, and this looks like a memorable night.

KPCC and "Off-Ramp" celebrated the 75th anniversary of the broadcast last year by distributing the original 1938 performance, and a new documentary, internationally... introduced by George Takei, another original Trek actor you might have heard of.

War of the Worlds: Sat., Jan. 17,  8 PM; The Acme Theatre, 135 North La Brea Ave. LA CA 90036

“How in the world am I going to come up with something to make dinner tonight?”

If you’ve found yourself asking this question repeatedly during the pandemic, you’re not alone. Grocery shopping complicated by COVID-19 and shortages of certain staples has meant that many who might not usually consider themselves home chefs have had no choice but to throw an apron on and do some culinary experimentation with whatever they already have in their kitchen and pantry. 

Last month on AirTalk, we tackled this issue by calling up pro chef Noelle Carter and food writer Russ Parson, both of whom are former members of the L.A. Times’ Food team, to answer your questions about how to cook with what you already have, recycle  certain foods, and even make staples that you might not be able to find in abundance right now. If you tuned in last time, you learned how to make your own pasta, how to regrow vegetables like green onions and romaine lettuce, and even what you can use as a substitute for all-purpose flour if you can’t find any at the store.

Legal Fight Heats Up In Texas Over Ban On Abortions Amid Coronavirus

Texas Gov. Greg Abbott signed an executive order banning all elective medical procedures, including abortions, during the coronavirus outbreak. The ban extends to medication abortions.; Credit: Eric Gay/AP

Nina Totenberg | NPR

Governors across the country are banning elective surgery as a means of halting the spread of the coronavirus. But in a handful of states that ban is being extended to include a ban on all abortions.

So far the courts have intervened to keep most clinics open. The outlier is Texas, where the U.S. Court of Appeals for the Fifth Circuit this week upheld the governor's abortion ban.

Four years ago, Texas was also the focus of a fierce legal fight that ultimately led to a U.S. Supreme Court ruling in which the justices struck down a Texas law purportedly aimed at protecting women's health. The court ruled the law was medically unnecessary and unconstitutional.

Now Texas is once again the epicenter of the legal fight around abortion. In other states--Ohio, Iowa, Alabama, and Oklahoma--the courts so far have sided with abortion providers and their patients.

Not so in Texas where Gov. Greg Abbott signed an executive order barring all "non-essential" medical procedures in the state, including abortion. The executive order was temporarily blocked in the district court, but the Fifth Circuit subsequently upheld the governor's order by a 2-to-1 vote, declaring that "all public constitutional rights may be reasonably restricted to combat a public health emergency."

"No more elective medical procedures can be done in the state because of the potential of needing both people ... beds and supplies, and obviously doctors and nurses," said Texas Attorney General Ken Paxton in an interview with NPR.

'Exploiting This Crisis'

Nancy Northrup, CEO of the Center for Reproductive Rights, sees things very differently. "It is very clear that anti-abortion rights politicians are shamelessly exploiting this crisis to achieve what has been their longstanding ideological goal to ban abortion in the U.S.," she said.

Paxton denies that, saying Texas "is not targeting any particular group."
The state's the "only goal is to protect people from dying," he said.

Yet the American Medical Association just last week filed a brief in this case in support of abortion providers, as did 18 states, led by New York, which is the state that has been the hardest hit by the coronavirus.

They maintain that banning abortion is far more dangerous,because it will force women to travel long distances to get one. A study from the Guttmacher Institute found that people seeking abortions during the COVID-19 outbreak would have to travel up to 20 times farther than normal if states successfully ban abortion care during the pandemic. The AMA also notes that pregnant women do not stop needing medical care if they don't get an abortion.

Northrup, of the Center for Reproductive Rights, sees this as more evidence that the ban is a calculated move by the state: what "puts the lie to this is the fact that they're trying to ban medication, abortion as well; that's the use of pills for abortion.

"Those do not need to take place in a clinic and they can be done, taken effectively by tele-medicine. So it shows that the real goal here, tragically, is shutting down one's right to make the decision to end the pregnancy, not a legitimate public health response."

'I Was Desperate'

Affidavits filed in the Texas case tell of harrowing experiences already happening as the result of the Texas ban. One declaration was filed by a 24-year-old college student. The week she lost her part-time job as a waitress, she found out she was pregnant. She and her partner agreed they wanted to terminate the pregnancy, and on March 20 she went to a clinic in Forth Worth alone; because of social distancing rules, her partner was not allowed to go with her.

Since she was 10 weeks pregnant, still in her first trimester, she was eligible for a medication abortion. Under state law, she had to wait 24 hours before getting the pills at the clinic, but the night before her scheduled appointment, the clinic called to cancel because of Abbott's executive order.

He partner was with her and we "cried together," she wrote in her declaration. "I couldn't risk the possibility that I would run out of time to have an abortion while the outbreak continued," and it "seemed to be getting more and more difficult to travel."

She made many calls to clinics in New Mexico and Oklahoma. The quickest option was Denver--a 12-hour drive, 780-mile drive from where she lives. Her partner was still working, so her best friend agreed to go with her. They packed sanitizing supplies and food in the car for the long drive and arrived at the Denver Clinic on March 26, where she noticed other cars with Texas plates in the parking lot, according to the affidavit.

At the clinic, she was examined, given a sonogram again, and because Colorado does not have a 24-hour waiting requirement, she was given her first abortion pill without delay and told she should try to get home within 30 hours to take the second pill.

She and her friend then turned around to go home. They were terrified she would have the abortion in the car, and tried to drive through without taking breaks. But after six hours, when it turned dark they were so exhausted they had to stop at a motel to catch some sleep. The woman finally got home and took the second pill just within the 30-hour window.

She said that despite the ordeal she was grateful she had the money, the car, the friend, and the supportive partner with a job, to make the abortion possible. Others will not be so lucky, she wrote. But "I was desperate and desperate people take desperate steps to protect themselves."

A 'Narrative' Of Choice

Paxton, the Texas attorney general, does not seem moved by the time limitations that pregnancy imposes, or the hardships of traveling out of state to get an abortion. He told NPR "the narrative has always been 'It's a choice' ... that's the whole narrative. I'm a little surprised by the question, given that's always been the thing."

On Thursday abortion providers and their patients returned to the district court in Texas instead of appealing directly to the U.S. Supreme Court to overturn the Fifth Circuit's ruling from earlier this week. The district court judge, who originally blocked the governor's ban, instead narrowed the governor's order so that medical abortions--with pills--would be exempt from the ban, as well as abortions for women who are up against the state-imposed deadline. Abortions in Texas are banned after 22 weeks.

In the end, though, this case may well be headed to the U.S. Supreme Court. And because of the addition of two Trump appointees since 2016--the composition of the court is a lot more hostile to abortion rights.

L.A. Philharmonic To Take Over Operations At Ford Theatre

Kyle Stokes

The L.A. Philharmonic will be the new operator of the John Anson Ford Theatre, the smaller outdoor venue near  the 101 Freeway across from the Hollywood Bowl, under a plan approved by the Los Angeles County Board of Supervisors.  

L.A.  funding sustains the Ford, and the county recently spent $80 million renovating the 1,200  seat amphitheater.  But attendance has been lackluster — and Supervisor Sheila Kuehl hopes the L.A. Philharmonic can change that. 

“The Ford will be able to take advantage of the natural synergies in marketing, capacity-building and program resources that simply haven’t been available to the Ford as an independent institution," she  said.

The move by the L.A. County  blindsided many local artists.  They say the Ford is an important incubator for diverse talent.  They also worry ticket prices will increase.  Prompted by their criticism, the Supervisors will require the Phil to meet with artists and annually review the diversity of the Ford’s shows with county officials.

FilmWeek®

Hollywood has come to a stand still. The film and entertainment industry has been hit hard by the coronavirus outbreak as theaters close, film releases and events are being postponed, and studios are putting a pause on film production.

The gravity of the coronavirus is being felt all throughout the country and Hollywood is not coming out of the outbreak unscathed. Social distancing measures being enforced to help control the outbreak has studios and theatres taking a huge hit. It’s predicted that about 170,000 people in the film industry will lose their jobs. Many of the lowest-paid positions and freelance jobs have been the first to go. From events to films, the industry is trying to strategize around the outbreak with no clear picture on how long these conditions could last. Hollywood unions, activist groups and nonprofits are coming together to help provide some kind of emergency relief for workers who are getting hit the hardest. It’s been a period of economic shock for the entertainment industry and it’s still too early to see what Hollywood could look like after the outbreak is over.

Today on AirTalk, we check-in with people in the entertainment industry who have been impacted by the outbreak and where might Hollywood go from here. If you work in entertainment, we'd like to hear from you! How are you coping as most productions are shut down? Join the live conversation by calling 866-893-5722.

Rivers can help reduce the Urban Heat Island effect

Heat waves are predicted to become more frequent under climate change, and are likely to be particularly severe in cities and towns due to the Urban Heat Island effect (UHI). A recent UK study of UHI mitigation strategies has demonstrated that even a small urban river can result in a cooling effect of 1??C during temperatures higher than 20??C, and that these cooling effects can be improved by careful urban design of the surrounding areas.

Dry soils exacerbated 2006 heatwave in Northern France

Dry soils and a lack of cloud cover help explain a major heatwave in France, concludes new research. The study indicates that the two drivers were separate, unlinked events that came together at the same time to worsen the 2006 heatwave. Its findings could allow heatwaves to be predicted more accurately to protect public health.

Future heatwaves in Europe will be most severe in the south

Heatwaves in Europe are likely to become more frequent and devastating, according to recent research. Climate change will lead to extended periods of high day and night-time temperatures, coupled with high humidity, and will particularly affect the Mediterranean coast and southern European river basins, where there are many densely populated urban areas.

The mega-heat wave of 2010 – implications for the future

New research has compared the hot summers of 2003 and 2010 in Europe. The results indicate that the extreme temperatures in 2010 affected an area that was about twice as large as the area affected in 2003. Climate change projections for Eastern and Western Europe suggest that such mega-heat waves will become more frequent in the upcoming decades.

Counteracting the urban heat island effect with effective planning

Climate change is likely to exacerbate the urban heat island (UHI) effect. A new study has therefore examined possible climate change adaptation measures that can alleviate the UHI effect and illustrated how these strategies can be practically applied. While the study provides real-life examples to demonstrate how the measures can be used, it does not include any quantitative assessment of their impacts.

Dealing with external costs of district heating plants

Researchers have evaluated how well Swedish policy instruments deal with external environmental costs associated with district heating (DH) plants. They found they have improved environmental performance, but for some plants, the costs of internalising external costs, in terms of taxes, emission permits and environmental fees, are higher than the environmental costs of pollution they produce.
