Based on a thorough review of clinical and epidemiological studies, neither the mercury-based vaccine preservative thimerosal nor the measles-mumps-rubella (MMR) vaccine are associated with autism, says a new report from the Institute of Medicine of the National Academies.

Scientific evidence links mold and other factors related to damp conditions in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people, says a new report from the Institute of Medicine of the National Academies.

The U.S. Environmental Protection Agencys standard for the maximum amount of fluoride allowed in drinking water -- 4 milligrams of fluoride per liter of water -- does not protect against adverse health effects.

Use of protective face coverings will be one of many strategies used to slow or prevent transmission of the flu virus in the event of a pandemic, even though scientific evidence about the effectiveness of inexpensive, disposable medical masks and respirators against influenza is limited.

The National Academy of Sciences (NAS) and Institute of Medicine (IOM) today released SCIENCE, EVOLUTION, AND CREATIONISM, a book designed to give the public a comprehensive and up-to-date picture of the current scientific understanding of evolution and its importance in the science classroom.

A National Research Council committee asked to examine the scientific approaches used and conclusions reached by the Federal Bureau of Investigation during its investigation of the 2001 Bacillus anthracis mailings has determined that it is not possible to reach a definitive conclusion about the origins of the anthrax in letters mailed to New York City and Washington, D.C., based solely on the available scientific evidence.

Despite being used for several decades, test-based incentives have not consistently generated positive effects on student achievement, says a new report from the National Research Council.

Research to date on the effect of capital punishment on homicide rates is not useful in determining whether the death penalty increases, decreases, or has no effect on these rates, says a new report from the National Research Council.

Young athletes in the U.S. face a culture of resistance to reporting when they might have a concussion and to complying with treatment plans.

Given the minimal impact of long prison sentences on crime prevention and the negative social consequences and burdensome financial costs of U.S. incarceration rates, which have more than quadrupled in the last four decades, the nation should revise current criminal justice policies to significantly reduce imprisonment rates, says a new report from the National Research Council.

There is no substitute for dramatic reductions in greenhouse gas emissions to mitigate the negative consequences of climate change, a National Research Council committee concluded in a two-volume evaluation of proposed climate-intervention techniques.

As immigrants and their descendants become integrated into U.S. society, many aspects of their lives improve, including measurable outcomes such as educational attainment, occupational distribution, income, and language ability, but their well-being declines in the areas of health, crime, and family patterns, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, will join Centers for Disease Control and Prevention Director Robert Redfield and other administration representatives in testifying before a Senate committee on May 12.

The announcement comes as members of President Trump's coronavirus task force are being asked to limit their appearances on Capitol Hill despite ongoing calls from lawmakers for more oversight into the administration's coronavirus response. Last week, the Trump administration blocked Fauci from appearing before a House committee on the subject of spending on coronavirus testing.

President Trump told reporters Tuesday that he doesn't want the officials appearing before House Democrats.

"The House is a setup," Trump said. "The House is a bunch of Trump haters."

White House officials gave a less adversarial explanation when justifying the decision to limit task force testimony in a memo to top congressional aides.

"For primary response departments, including HHS, DHS, and State, in order to preserve department-wide resources, no more than one COVID-related hearing should be agreed to with the department's primary House and Senate authorizing committee and appropriations subcommittee in the month of May, for a total of no more than four COVID-related hearings department-wide," the memo stated.

Congressional Democrats are demanding greater oversight over the roughly $3 trillion that has already been approved for the coronavirus response. House Speaker Nancy Pelosi, D-Calif., has launched a new select committee to conduct the oversight, but Republicans have so far refused to name members to the panel despite the plan to make the panel bipartisan.

The Senate hearing was announced shortly after the administration sent the memo to Capitol Hill banning committee appearances from task force members during May unless approved by the White House chief of staff.

Deputy White House Press Secretary Judd Deere said the decision to block Fauci from the House committee appearance was intended to allow him to focus on his primary task of overseeing the coronavirus response.

"While the Trump Administration continues its whole-of-government response to COVID-19, including safely opening up America again and expediting vaccine development, it is counter-productive to have the very individuals involved in those efforts appearing at Congressional hearings," Deere said. "We are committed to working with Congress to offer testimony at the appropriate time."

Fauci, Redfield, HHS Assistant Secretary Brett Giroir and FDA Commissioner Stephen Hahn are scheduled to discuss "safely getting back to work and back to school" when they appear before the Health, Education, Labor and Pensions — or HELP — Committee next Tuesday.

Senate Democrats, including Patty Murray, D-Wash., the top Democrat on the HELP committee, have called for the administration to provide greater transparency and a nationwide plan for testing. So far their demands have not received a response.

"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."

We started our new schedule for "AirTalk" this week. With the expansion of "Brand & Martinez" to two hours, we're now on from 11 a.m. to 1 p.m. Friday's Film Week on AirTalk moves into the noon hour.

I’ve been asked many times in the past couple of days how I feel about the shift. My answer is that it’s working out great for our “AirTalk” team.  We still get in at 8 each morning, but now have three hours to prepare our timeliest topics. It also puts us into the noon hour, where we have the chance to connect with folks heading to lunch. 

I know it’s not all good for some listeners, who might have a harder time listening an hour later. There are also, undoubtedly, fans of “The World” who would’ve rather had it stay at noon instead of moving to 2 p.m. I hope you’ll give us a chance in the new slot and that you find the new lineup still fits your schedule. 

If it doesn’t, remember that you can hear all of our local programs online, at the time of your choosing, at www.kpcc.org.

As for the irreplaceable Patt Morrison, she’ll continue to provide her talents to KPCC listeners with regular features and interviews throughout our day. Though I know many fans of Patt are very sad to see her daily program end, I think Patt’s high-profile segments will be a terrific boost to all the other shows where they’ll be heard.

This will make Patt a presence everywhere on our schedule, including “AirTalk,” which is pretty exciting.

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.}

For years, I’d feared the worst. Behind that intrusive belt of chain link and green canvas fence, with all the hidden noise of power digging machines, smashing jackhammers and growling tractors going on behind it, and heaps of dirt piled high, I dreaded that something terrible was going on in the dark, hidden heart of our dear old Huntington.

We were promised a new visitor center, a new store, a new cafe and restaurant. I imagined the Disney-fied worst: Henry Huntington’s Roller Coaster Red Car Ride; Pinky’s Pinkberry Parlor. The Blue Boy Fashion Center. Maybe even a giant Rem Koolhaas-LACMA style amoeba of purple reinforced concrete sprawling all over the lawns between the library and the old gallery.

My fears were groundless. The $68 million (not much more than the Getty paid for its new Manet) 52,000 square foot Education and Visitor Center addition is in perfect harmony with the early 20th Century original library and art gallery, perhaps more so than some previous increments, such as the nearby and blankly imposing Munger Research Center. 

The addition is named after outgoing Huntington chief Steven S. Koblik, who engineered much of the funding and planning for the facility. He’s got something to be proud of in his retirement: a new garden-centered segment of new facilities that founder, pioneer transit tycoon Henry Huntington, would probably have enthused over.

With its mighty $400 million endowment and the muscular fundraising power that enticed squillionaire Charlie Munger to donate hugely to this project (not to mention that research center), the venerable Huntington institution could have easily erected something expensively and grandiloquently modern.  

But its directorate and patrons seem to understand an important fact about the place: Most visitors don’t go there to be dazzled. We go there to be enthralled, even comforted by the century-old institution’s enduring and deeply reassuring ambiance that we are privileged to inhabit during our visits to its galleries of great art, its acreage of exquisite gardens and Arcadian vistas.

The Huntington possesses what designer Sheryl Barton, who co-created the new landscaping with the Huntington’s Jim Folsom, spoke of at the opening press conference as “the choreography of experience.”

That experience includes the new California-Mediterranean groves and gardens and the low-lying new structure that includes an expanded store, new classrooms, courts, cafes and an auditorium. With its simple, Tuscan-columned loggias and red-tiled roofs (and, oh, yes, even that showy glass dome on the Rose Hills Foundation Garden Court), it all effortlessly blends into the traditional whole.

Although the Huntington doesn’t seem to be planning on a new influx of visitors, it’s hard to see this new, more user-friendly front office isn’t going to attract more people to its San Marino location than the current 600,000 per year.

Particularly considering how regional museum attendance in general has boomed over recent decades. Will this abate the quiet private experience many of us Huntington fans have shared and treasured over the years?

Probably. But there will also be important new things to see — like  Alexander Calder’s 12-by-20-foot Jerusalem Stabile, which beckons you into the new addition, and two powerful, newly acquired murals by the great 20th Century California artists Millard Sheets and Doyle Lane. Plus a new and glorious vista from the cafe’s terrace over to the original old Huntington villa — now gallery — where all this began, over a century ago.
