The interoperability of chemical and biological crystallographic data is a key challenge to research and its application to pharmaceutical design. Research attempting to combine data from the two disciplines, small-molecule or chemical crystallography (CX) and macromolecular crystallography (MX), will face unique challenges including variations in terminology, software development, file format and databases which differ significantly from CX to MX. This perspective overview spans the two disciplines and originated from the investigation of protein binding to model radiopharmaceuticals. The opportunities of interlinked research while utilizing the two databases of the CSD (Cambridge Structural Database) and the PDB (Protein Data Bank) will be highlighted. The advantages of software that can handle multiple file formats and the circuitous route to convert organometallic small-molecule structural data for use in protein refinement software will be discussed. In addition some pointers to avoid being shipwrecked will be shared, such as the care which must be taken when interpreting data precision involving small molecules versus proteins.

What an animal eats is a fundamental aspect of its biology, but surprisingly, the evolution of diet had not been studied across the animal kingdom until now. Scientists at the University of Arizona report several unexpected findings from taking a deep dive into the evolutionary history of more than one million animal species and going back 800 million years, when the first animals appeared on our planet. The study revealed several surprising key insights: Many species living today that are carnivorous, meaning they eat other animals, can trace this diet back to a common ancestor more than 800 million years ago; A plant-based, or herbivorous, diet is not the evolutionary driver for new species that it was believed to be; Closely related animals tend to share the same dietary category -- plant-eating, meat-eating, or both. This finding implies that switching between dietary lifestyles is not something that happens easily and often over the course of evolution.

On Broad Beach in Malibu, high tide not only wets sand but also retaining walls and broken down rock revetments. What happens next in homeowners' efforts to get sand trucked in here will go to the State Lands Commission - and the next Controller likely will weigh in on the problem. ; Credit: Molly Peterson/KPCC

The most common question I’ve been asked about the statewide Controller race this election year is the same question I get every four years. “Wait, we have one?”

The inevitable follow-up question: “What does this person do?” Down-ballot races in California’s state election can seem like a tedious part of a the voting process. Most of us just don't take the time to research them. In 2010, the last time we elected statewide executives, 435,308 of those people who voted for Governor just didn’t bother to vote for anybody in the Controller race. 

But in addition to being the chief fiscal officer of the 8th-largest economy in the world, the Controller sits on something like 80 state commissions and boards. And if you’re interested in California’s environment, a biggie there is the State Lands Commission.

The State Lands Commission oversees roughly 4 million acres of submerged land and tidelands, holding them in trust for the public. Right now it's looking at policy alternatives to respond to sea level rise. It manage the state's offshore oil-drilling leases. It even gets authority over historical shipwrecks! 

Three issues coming before to the Lands Commission mean the Controller matters:  

• Coastal Access and Martin’s Beach: At the end of September, Governor Jerry Brown signed a law requiring the State Lands Commission to negotiate with Vinod Khlosa, a private property owner who famously shut down coastal access over his land this year. The commission has all of next year to negotiate with Khlosa. If no deal is reached, it can use eminent domain authority to force public access – something that would represent a big break in historical practice, because that authority hasn’t ever been used in the 76 years that the commission has existed.
• Malibu’s Broad Beach has been rapidly eroding under pressure of waves and storms worsened by climate change, and very rich homeowners there have been seeking to add sand in front of their houses to combat the risk of damage to very expensive properties. Earlier this year, those homeowners successfully completed an application to the State Lands Commission, and the commission was expected to decide on it in October. The decision’s been put over till after the election.
• Fracking: Offshore oil made news late last year and earlier this year when some operators didn’t report that they were using drilling and production techniques collectively referred to as hydraulic fracturing. The news prompted the EPA to require chemical disclosures for drilling operations it oversees.  The state agencies that should be overseeing these issues – the Coastal Commission and the Lands Commission – are considering their next moves too.

Positions on these issues don’t really come up when it comes to the Controller race, though both Betty Yee and Ashley Swearengin have gone on the record to say they’re against fracking.

"Deepfakes" are digitally altered images that make incidents appear real when they are not. Such altered files could have broad implications for politics.; Credit: /Marcus Marritt for NPR

Sophisticated fake media hasn't emerged as a factor in the disinformation wars in the ways once feared — and two specialists say it may have missed its moment.

Deceptive video and audio recordings, often nicknamed "deepfakes," have been the subject of sustained attention by legislators and technologists, but so far have not been employed to decisive effect, said two panelists at a video conference convened on Wednesday by NATO.

One speaker borrowed Sherlock Holmes' reasoning about the significance of something that didn't happen.

"We've already passed the stage at which they would have been most effective," said Keir Giles, a Russia specialist with the Conflict Studies Research Centre in the United Kingdom. "They're the dog that never barked."

The perils of deepfakes in political interference have been discussed too often and many people have become too familiar with them, Giles said during the online discussion, hosted by NATO's Strategic Communications Centre of Excellence.

Following all the reports and revelations about election interference in the West since 2016, citizens know too much to be hoodwinked in the way a fake video might once have fooled large numbers of people, he argued: "They no longer have the power to shock."

Tim Hwang, director of the Harvard-MIT Ethics and Governance of AI Initiative, agreed that deepfakes haven't proven as dangerous as once feared, although for different reasons.

Hwang argued that users of "active measures" (efforts to sow misinformation and influence public opinion) can be much more effective with cheaper, simpler and just as devious types of fakes — mis-captioning a photo or turning it into a meme, for example.

Influence specialists working for Russia and other governments also imitate Americans on Facebook, for another example, worming their way into real Americans' political activities to amplify disagreements or, in some cases, try to persuade people not to vote.

Other researchers have suggested this work continues on social networks and has become more difficult to detect.

Defense is stronger than attack

Hwang also observed that the more deepfakes are made, the better machine learning becomes at detecting them.

A very sophisticated, real-looking fake video might still be effective in a political context, he acknowledged — and at a cost to create of around $10,000, it would be easily within the means of a government's active measures specialists.

But the risks of attempting a major disruption with such a video may outweigh an adversary's desire to use one. People may be too media literate, as Giles argued, and the technology to detect a fake may mean it can be deflated too swiftly to have an effect, as Hwang said.

"I tend to be skeptical these will have a large-scale impact over time," he said.

One technology boss told NPR in an interview last year that years' worth of work on corporate fraud protection systems has given an edge to detecting fake media.

"This is not a static field. Obviously, on our end we've performed all sorts of great advances over this year in advancing our technology, but these synthetic voices are advancing at a rapid pace," said Brett Beranek, head of security business for the technology firm Nuance. "So we need to keep up."

Beranek described how systems developed to detect telephone fraudsters could be applied to verify the speech in a fake clip of video or audio.

Corporate clients that rely on telephone voice systems must be wary about people attempting to pose as others with artificial or disguised voices. Beranek's company sells a product that helps to detect them and that countermeasure also works well in detecting fake audio or video.

Machines using neural networks can detect known types of synthetic voices. Nuance also says it can analyze a recording of a real known voice — say, that of a politician — and then contrast its characteristics against a suspicious recording.

Although the world of cybersecurity is often described as one in which attackers generally have an edge over defenders, Beranek said he thought the inverse was true in terms of this kind of fraud detection.

"For the technology today, the defense side is significantly ahead of the attack side," he said.

Shaping the battlefield

Hwang and Giles acknowledged in the NATO video conference that deepfakes likely will proliferate and become lower in cost to create, perhaps becoming simple enough to make with a smartphone app.

One prospective response is the creation of more of what Hwang called "radioactive data" — material earmarked in advance so that it might make a fake easier to detect.

If images of a political figure were so tagged beforehand, they could be spotted quickly if they were incorporated by computers into a deceptive video.

Also, the sheer popularity of new fakes, if that is what happens, might make them less valuable as a disinformation weapon. More people could become more familiar with them, as well as being detectable by automated systems — plus they may also have no popular medium on which to spread.

Big social media platforms already have declared affirmatively that they'll take down deceptive fakes, Hwang observed. That might make it more difficult for a scenario in which a politically charged fake video went viral just before Election Day.

"Although it might get easier and easier to create deepfakes, a lot of the places where they might spread most effectively, your Facebooks and Twitters of the world, are getting a lot more aggressive about taking them down," Hwang said.

That won't stop them, but it might mean they'll be relegated to sites with too few users to have a major effect, he said.

"They'll percolate in these more shady areas."

Two years after it released the first season of the show 13 Reasons Why with a graphic suicide scene, Netflix has announced that it has edited it out.

The show is centered on the suicide of fictional teen Hannah Baker, and the first season's finale shows her taking her own life. Several organizations, including the National Association of School Psychologists, raised concerns that it could romanticize suicide for vulnerable teens.

"Our creative intent in portraying the ugly, painful reality of suicide in such graphic detail in Season 1 was to tell the truth about the horror of such an act, and make sure no one would ever wish to emulate it," show creator Brian Yorkey said in a statement. "But as we ready to launch Season 3, we have heard concerns about the scene from Dr. Christine Moutier at the American Foundation for Suicide Prevention and others, and have agreed with Netflix to re-edit it."

"No one scene is more important than the life of the show, and its message that we must take better care of each other," he added. "We believe this edit will help the show do the most good for the most people while mitigating any risk for especially vulnerable young viewers."

After some initial criticism, Netflix added a warning card to the beginning of the episode, alerting viewers that the episode contained "graphic depictions of suicide and violence."

The show also has a website, 13reasonswhy.info, containing resources about suicide prevention. It contains videos of cast members discussing topics such as bullying, consent, depression and how to talk with a teen about the series. The site also warns: "If you are struggling, this series may not be right for you or you may want to watch it with a trusted adult."

The edited version, now on Netflix, shows Hannah looking at herself in the mirror, full of emotion. It then cuts to her parents finding her body in the bathroom and reacting to her death. The previous version was nearly three minutes long, according to The Hollywood Reporter, and showed her cutting her wrists with a razor blade.

Netflix's decision has drawn praise from a number of suicide prevention advocates, such as American Association of Suicidology, American Foundation for Suicide Prevention, American School Counselor Association, Dr. Helen Hsu from Stanford, advocacy group Mental Health America, the Trevor Project and Dr. Rebecca Hedrick from Cedars-Sinai, according to THR.

"We support the decision to edit the scene in which Hannah takes her own life from 13 Reasons Why. There has been much debate about the series in the medical community," they said in a joint statement, as THR reported. "But this positive change will ensure that 13 Reasons Why continues to encourage open conversation about mental health and suicide prevention — while also mitigating the risk for the most vulnerable teenage viewers."

Ron Avi Astor at the University of Southern California, who studies adolescent bullying and mental health, discussed with NPR's Anya Kamenetz how the images of self-harm on the show could affect teens.

Avi Astor told Kamenetz that the depiction could be contagious — but just for certain teens. "It's not just that any random kid would see it and do it," he said, but for a kid who was already thinking about suicide, it had the potential to influence their behavior.

If you or someone you know may be considering suicide, contact the National Suicide Prevention Lifeline at 1-800-273-8255 (En Español: 1-888-628-9454; Deaf and Hard of Hearing: 1-800-799-4889) or the Crisis Text Line by texting HOME to 741741.

Life is already hard enough, but with teen daughters—  of which I have two, ages 15 and 16 -- well, let's just say that, what with everything going on these days, my mind is a bit addled. And my latest TV obsession isn't exactly helping.

"I have such a sense of dystopia," I complained to my friend Carol. 

She replied: "Maybe you should stop binge-watching The Handmaid's Tale!

It's true.  I've watched so many hours of The Handmaid's Tale, I've started to involuntarily greet people with, "Blessed be the day," "Blessed be!"  If that's not  familiar to you, you're probably not aware that in the oppressive futuristic society depicted here—?   Fertile young women are farmed out to "commanders" and forced to have sex with them between their wives' legs, in order to birth mutant babies. . .

I'm old enough to remember "Happy Days."  Do you remember the sitcom "Happy Days"?  What was it about?  Days. . . that were Happy!  Teens hanging around the jukebox!  With poodle skirts!  The Fonz!  Having shenanigans! 

So I resolve to turn off the news—  Except for the headlines that actually leap out of the radio—  And maul you, like a wolverine—   Ever seen that?  Anyway—

I also take a break from The Handmaid's Tale—  I turn instead to the comedy Grace and Frankie, with Jane Fonda and Lily Tomlin!  I embrace their comforting presences like the stylish pashmina throw either might wear—  If The Cheese Nun was still on?  I would binge-watch that!  Very reassuring.  The Cheese and the Nun.

But then I start getting emails -- the Concerned Parent E-Blasts I don't recall ever signing up for, a la—?  "Does your teen get enough sleep?"  No.  "Is your teen ready for the SAT?"  No. "Does your teen eat too much sugar and waste a lot of time?"  Yes.   Apparently that's abnormal behavior and there's medication for that.  Good to know!

 Well—  The truly alarming news is that—  Often unbeknownst to their parents— All of our teens are secretly watching this new TV series called "13 Reasons Why."  As in, 13 reasons why this teenage girl commits suicide.  She leaves behind the reasons in a box of tapes.  One reason is rape.  Shown on screen. 

It's a long way from Happy Days.

As a responsible parent, I need to talk to my daughters. . . about this show.

 Next week: A Visit with Dr. Mom.

This content is from Southern California Public Radio. View the original story at SCPR.org.

Life is stressful enough.  And now—?  I've been getting all these alarming missives from parenting organizations about the Netflix series "13 Reasons Why."  As in, 13 reasons why this teenaged girl commits suicide—  Which is depicted on screen, as is a rape!  Yikes!  Apparently all teens are secretly streaming it, so we parents need to open up the conversation.

But then I'm thinking: What if my two teen daughters are the only teens not watching it?  And then my raising the topic would be—what do you call it?  A trigger?  It's so confusing these days!  College campuses are full of "safe spaces"—  But middle schoolers can stream suicide shows!

And my younger daughter?  She's already fluttery, like a leaf.  Sample text—and I can't convey how terrifying these words look on one's phone: "Mom.  Mom.  Mom.  Please!  I'm so scared.  I don't know what to do!  Help me!"  Situation?  She was in the bathroom at Starbucks and the toilet wouldn't flush.  Fortunately Dr. Mom was right outside the door.

So with this one, driving home from school, I just ask, with an odd vague heartiness: "So. . . What movies or TV shows are all the kids watching these days?"

"All the kids?" she says.  "What are you talking about?  What kids?"

"You kids!" I say.  "You!  You and your peeps!"

"What?" she says.  "Nothing."  She goes on instead to describe her traumatic field trip.  Instead of studying tide pools at a nice quiet museum, her class went to the actual beach!  She slipped on a rock and all these kids from the Medical Magnet too-eagerly stormed her with gauze and bandages! 

Okay.  I'll let that fragile kid be.  Now it's on to my older, more sophisticated daughter.  The one with the nose ring—at least it's fake.  I ask her bluntly: "So, what's the deal with this '13 Reasons Why' show?"

 She groans.  "I already read the book back in sixth grade."
 

"In sixth grade?" I exclaim.

Apparently at her old middle school, everyone was reading books about teen suicide—  Which appears to have been an actual cottage industry, possibly it's own Young Adult genre.  Sheesh!  What happened to Nancy Drew?

She says she did watch the show but stopped during the rape scene, which was a bit much.  In fact, now, on social media, the show's premise had surfaced as a joke meme.  As in, "I asked to borrow a pencil.  You said you didn't have one."  Ominous pause.  "It's one of the 13 Reasons Why." Ba-dum-bum.

In the end, Dr. Mom felt a bit out of her league.  I guess I'll just have to trust that the teens are going to be fine.  And to be on hand to flush the toilet.}
