3D electron diffraction (3DED) is increasingly employed to determine molec­ular and crystal structures from micro-crystals. Indomethacin is a well known, marketed, small-molecule non-steroidal anti-inflammatory drug with eight known polymorphic forms, of which four structures have been elucidated to date. Using 3DED, we determined the structure of a new ninth polymorph, σ, found within an amorphous solid dispersion, a product formulation sometimes used for active pharmaceutical ingredients with poor aqueous solubility. Subsequently, we found that σ indomethacin can be produced from direct solvent evaporation using di­chloro­methane. These results demonstrate the relevance of 3DED within drug development to directly probe product formulations.

The interaction of intense synchrotron radiation with molecular crystals frequently modifies the crystal structure by breaking bonds, producing fragments and, hence, inducing disorder. Here, a second-rank tensor of radiation-induced lattice strain is proposed to characterize the structural susceptibility to radiation. Quantitative estimates are derived using a linear response approximation from experimental data collected on three materials Hg(NO3)2(PPh3)2, Hg(CN)2(PPh3)2 and BiPh3 [PPh3 = triphenylphosphine, P(C6H5)3; Ph = phenyl, C6H5], and are compared with the corresponding thermal expansivities. The associated eigenvalues and eigenvectors show that the two tensors are not the same and therefore probe truly different structural responses. The tensor of radiative expansion serves as a measure of the susceptibility of crystal structures to radiation damage.

An attempt to explore the reactivity of the nitro group in the presence of gold catalysis in comparison to the azide group yielded intriguing results. Surprisingly, only the nitro group exhibited reactivity, ultimately giving rise to the formation of the title isatogen, C14H8N4O2. In the crystal structure, weak C—H⋯O hydrogen bonds and π–π stacking inter­actions link the mol­ecules. The structure exhibits disorder of the mol­ecule.

The complex, tri­chlorido­(1,4,11-tri­aza-8-azonia­tetra­cyclo­[6.6.2.04,16.011,15]hexa­decane 1-oxide-κO)zinc(II) monohydrate, [ZnCl3(C12H23N4O)]·H2O, (I), has monoclinic symmetry (space group P21/n) at 120 K. The zinc(II) center adopts a slightly distorted tetra­hedral coordination geometry and is coordinated by three chlorine atoms and the oxygen atom of the oxidized tertiary amine of the tetra­cycle. The amine nitro­gen atom, inside the ligand cleft, is protonated and forms a hydrogen bond to the oxygen of the amine oxide. Additional hydrogen-bonding inter­actions involve the protonated amine, the water solvate oxygen atom, and one of the chloro ligands.

Three new 1H-indole derivatives, namely, 2-(bromo­meth­yl)-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C16H14BrNO2S, (I), 2-[(E)-2-(2-bromo-5-meth­oxy­phen­yl)ethen­yl]-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C24H20BrNO3S, (II), and 2-[(E)-2-(2-bromo­phen­yl)ethen­yl]-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C23H18BrNO2S, (III), exhibit nearly orthogonal orientations of their indole ring systems and sulfonyl-bound phenyl rings. Such conformations are favourable for inter­molecular bonding involving sets of slipped π–π inter­actions between the indole systems and mutual C—H⋯π hydrogen bonds, with the generation of two-dimensional monoperiodic patterns. The latter are found in all three structures, in the form of supra­molecular columns with every pair of successive mol­ecules related by inversion. The crystal packing of the compounds is additionally stabilized by weaker slipped π–π inter­actions between the outer phenyl rings (in II and III) and by weak C—H⋯O, C—H⋯Br and C—H⋯π hydrogen bonds. The structural significance of the different kinds of inter­actions agree with the results of a Hirshfeld surface analysis and the calculated inter­action energies. In particular, the largest inter­action energies (up to −60.8 kJ mol−1) are associated with pairing of anti­parallel indole systems, while the energetics of weak hydrogen bonds and phenyl π–π inter­actions are comparable and account for 13–34 kJ mol−1.

In the title mol­ecule, C11H11BrO3, the di­hydro­indene moiety is essentially planar but with a slight twist in the saturated portion of the five-membered ring. The meth­oxy groups lie close to the above plane. In the crystal, π-stacking inter­actions between six-membered rings form stacks of mol­ecules extending along the a-axis direction, which are linked by weak C—H⋯O and C—H⋯Br hydrogen bonds. A Hirshfeld surface analysis was performed showing H⋯H, O⋯H/H⋯O and Br⋯H/H⋯Br contacts make the largest contributions to inter­molecular inter­actions in the crystal.

Two new [1-(phenyl­sulfon­yl)-1H-indol-2-yl]methanamine derivatives, namely, N-(3-meth­oxy­phen­yl)-N-{[1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}acetamide, C24H22N2O4S, (I), and N-(2,5-di­meth­oxy­phen­yl)-N-{[1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}benzene­sulfonamide, C29H26N2O6S2, (II), reveal a nearly orthogonal orientation of their indole ring systems and sulfonyl-bound phenyl rings. The sulfonyl moieties adopt the anti-periplanar conformation. For both compounds, the crystal packing is dominated by C—H⋯O bonding [C⋯O = 3.312 (4)–3.788 (8) Å], with the structure of II exhibiting a larger number, but weaker bonds of this type. Slipped π–π inter­actions of anti­parallel indole systems are specific for I, whereas the structure of II delivers two kinds of C—H⋯π inter­actions at both axial sides of the indole moiety. These findings agree with the results of Hirshfeld surface analysis. The primary contributions to the surface areas are associated with the contacts involving H atoms. Although II manifests a larger fraction of the O⋯H/H⋯O contacts (25.8 versus 22.4%), most of them are relatively distal and agree with the corresponding van der Waals separations.

Crystallization of 5-nona­noyl-8-hy­droxy­quinoline in the presence of InCl3 in aceto­nitrile yields a dinuclear InIII complex crystallizing in the space group Poverline{1}. In this complex, [In2(C18H22NO2)2Cl4(H2O)2], each indium ion is sixfold coordinated by two chloride ions, one water mol­ecule and two 8-quinolino­late ions. The crystal of the title complex is composed of two-dimensional supra­molecular aggregates, resulting from the linkage of the Owater—H⋯O=C and Owater—H⋯Cl hydrogen bonds as well as bifurcated Carene—H⋯Cl contacts.

Two new phenyl­sulfonyl­indole derivatives, namely, N-{[3-bromo-1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}-N-(4-bromo-3-meth­oxy­phen­yl)benzene­sulfonamide, C28H22Br2N2O5S2, (I), and N,N-bis­{[3-bromo-1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}benzene­sulfonamide, C36H27Br2N3O6S3, (II), reveal the impact of intra­molecular π–π inter­actions of the indole moieties as a factor not only governing the conformation of N,N-bis­(1H-indol-2-yl)meth­yl)amines, but also significantly influencing the crystal patterns. For I, the crystal packing is dominated by C—H⋯π and π–π bonding, with a particular significance of mutual indole–indole inter­actions. In the case of II, the mol­ecules adopt short intra­molecular π–π inter­actions between two nearly parallel indole ring systems [with the centroids of their pyrrole rings separated by 3.267 (2) Å] accompanied by a set of forced Br⋯O contacts. This provides suppression of similar inter­actions between the mol­ecules, while the importance of weak C—H⋯O hydrogen bonding to the packing naturally increases. Short contacts of the latter type [C⋯O = 3.389 (6) Å] assemble pairs of mol­ecules into centrosymmetric dimers with a cyclic R22(13) ring motif. These findings are consistent with the results of a Hirshfeld surface analysis and together they suggest a tool for modulating the supra­molecular behavior of phenyl­sulfonyl­ated indoles.

Characterization of a material structure with pair distribution function (PDF) analysis typically involves refining a structure model against an experimental data set, but finding or constructing a suitable atomic model for PDF modelling can be an extremely labour-intensive task, requiring carefully browsing through large numbers of possible models. Presented here is POMFinder, a machine learning (ML) classifier that rapidly screens a database of structures, here polyoxometallate (POM) clusters, to identify candidate structures for PDF data modelling. The approach is shown to identify suitable POMs from experimental data, including in situ data collected with fast acquisition times. This automated approach has significant potential for identifying suitable models for structure refinement to extract quantitative structural parameters in materials chemistry research. POMFinder is open source and user friendly, making it accessible to those without prior ML knowledge. It is also demonstrated that POMFinder offers a promising modelling framework for combined modelling of multiple scattering techniques.

This article describes a correction procedure for the removal of indirect background contributions to measured small-angle X-ray scattering patterns. The high scattering power of a sample in the ultra-small-angle region may serve as a secondary source for a window placed in front of the detector. The resulting secondary scattering appears as a sample-dependent background in the measured pattern that cannot be directly subtracted. This is an intricate problem in measurements at ultra-low angles, which can significantly reduce the useful dynamic range of detection. Two different procedures are presented to retrieve the real scattering profile of the sample.

Macromolecular crystallography contributes significantly to understanding diseases and, more importantly, how to treat them by providing atomic resolution 3D structures of proteins. This is achieved by collecting X-ray diffraction images of protein crystals from important biological pathways. Spotfinders are used to detect the presence of crystals with usable data, and the spots from such crystals are the primary data used to solve the relevant structures. Having fast and accurate spot finding is essential, but recent advances in synchrotron beamlines used to generate X-ray diffraction images have brought us to the limits of what the best existing spotfinders can do. This bottleneck must be removed so spotfinder software can keep pace with the X-ray beamline hardware improvements and be able to see the weak or diffuse spots required to solve the most challenging problems encountered when working with diffraction images. In this paper, we first present Bragg Spot Detection (BSD), a large benchmark Bragg spot image dataset that contains 304 images with more than 66 000 spots. We then discuss the open source extensible U-Net-based spotfinder Bragg Spot Finder (BSF), with image pre-processing, a U-Net segmentation backbone, and post-processing that includes artifact removal and watershed segmentation. Finally, we perform experiments on the BSD benchmark and obtain results that are (in terms of accuracy) comparable to or better than those obtained with two popular spotfinder software packages (Dozor and DIALS), demonstrating that this is an appropriate framework to support future extensions and improvements.

Serial crystallography (SX) involves combining observations from a very large number of diffraction patterns coming from crystals in random orientations. To compile a complete data set, these patterns must be indexed (i.e. their orientation determined), integrated and merged. Introduced here is TORO (Torch-powered robust optimization) Indexer, a robust and adaptable indexing algorithm developed using the PyTorch framework. TORO is capable of operating on graphics processing units (GPUs), central processing units (CPUs) and other hardware accelerators supported by PyTorch, ensuring compatibility with a wide variety of computational setups. In tests, TORO outpaces existing solutions, indexing thousands of frames per second when running on GPUs, which positions it as an attractive candidate to produce real-time indexing and user feedback. The algorithm streamlines some of the ideas introduced by previous indexers like DIALS real-space grid search [Gildea, Waterman, Parkhurst, Axford, Sutton, Stuart, Sauter, Evans & Winter (2014). Acta Cryst. D70, 2652–2666] and XGandalf [Gevorkov, Yefanov, Barty, White, Mariani, Brehm, Tolstikova, Grigat & Chapman (2019). Acta Cryst. A75, 694–704] and refines them using faster and principled robust optimization techniques which result in a concise code base consisting of less than 500 lines. On the basis of evaluations across four proteins, TORO consistently matches, and in certain instances outperforms, established algorithms such as XGandalf and MOSFLM [Powell (1999). Acta Cryst. D55, 1690–1695], occasionally amplifying the quality of the consolidated data while achieving superior indexing speed. The inherent modularity of TORO and the versatility of PyTorch code bases facilitate its deployment into a wide array of architectures, software platforms and bespoke applications, highlighting its prospective significance in SX.

In synchrotron X-ray radiography, achieving high image resolution and an optimal signal-to-noise ratio (SNR) is crucial for the subsequent accurate image analysis. Traditional methods often struggle to balance these two parameters, especially in situ applications where rapid data acquisition is essential to capture specific dynamic processes. For quantitative image data analysis, using monochromatic X-rays is essential. A double multilayer monochromator (DMM) is successfully used for this aim at the BAMline, BESSY II (Helmholtz Zentrum Berlin, Germany). However, such DMMs are prone to producing an unstable horizontal stripe pattern. Such an unstable pattern renders proper signal normalization difficult and thereby causes a reduction of the SNR. We introduce a novel approach to enhance SNR while preserving resolution: dynamic tilting of the DMM. By adjusting the orientation of the DMM during the acquisition of radiographic projections, we optimize the X-ray imaging quality, thereby enhancing the SNR. The corresponding shift of the projection during this movement is corrected in post-processing. The latter correction allows a good resolution to be preserved. This dynamic tilting technique enables the homogenization of the beam profile and thereby effectively reduces noise while maintaining high resolution. We demonstrate that data captured using this proposed technique can be seamlessly integrated into the existing radiographic data workflow, as it does not need hardware modifications to classical X-ray imaging beamline setups. This facilitates further image analysis and processing using established methods.

A new guild study says women and minorities were largely shut out of the ranks of TV directors again last season.

The Directors Guild of America report released Wednesday said employers have made no significant improvement in diversity hiring for TV series in the last four years.

According to the study, white males directed the vast majority of the 3,500 cable, broadcast and high-budget online episodes made for the 2013-14 season.

The same holds true for the three previous years, according to guild findings.

In a statement, Directors Guild President Paris Barclay said it can be "shockingly difficult" to persuade those who control industry hiring to make even small improvements.

Growing up, Drew Arriola-Sands' music was "too weird for the weird kids." Her first band couldn't even get a backyard gig, but since Sands transitioned in 2013, her current band, Trap Girl, have been at the center of an exploding queer hardcore scene in Los Angeles. 

NOTE: Trans Pride L.A. is taking place this weekend, Saturday June 17, at the Los Angeles LGBT Center. To hear a preview of the event with organizer Gina Bigham, listen to the extra audio on this post.

Sands is 28 now, but she's always been drawn to glamorous women with big hair. Her mirror is adorned with pictures of Ronnie Spector, Dolly Parton, and Jayne Mansfield. Wig idols, she calls them. Sands has a large collection of wigs, and even makes her own, but it all started 20 years ago.

"When I was a little kid, my mom always had short black hair," Sands remembers. "And then one day, getting ready for school, she walked out of the bathroom with a long, thick, black braid with a ribbon on it, and it freaked me out, because I never saw her with long hair. So I was like, 'That’s weird! What is it?'" She was eight years old. For weeks to come, Sands would lock herself in the bathroom and stare at the extension braid in it's clear, Avon box until her mother threw it away without warning. The seed had been planted, though.

Her love of singing came at an early age too. As a child, Sands would stand up on a chair while watching baseball with her father to sing the national anthem. Her mother would scold her for being loud and tell her that she could sing at a baseball game when she was older. At 11, her father put her in little league.

We look at a picture of young Drew in a baseball jersey. Sands was a chubby little kid, biting down a smile, and burying her hand in her mitt. "I was a 'catcher' even then," laughs Sands.

"I was told I was gay before I even knew I was gay, because people saw I was feminine, did things a little different, spoke a little different, a little more sensitive," says Sands. Bullying was a consistent part of her childhood, with no one incident standing out because there was always "80 more horrible ones," she says. But she found ways to cope through her hobbies.

Her father said if she wasn't going to play a sport, she had to play an instrument. The first instrument she started with in earnest was the guitar, before picking up bass and more. "Nirvana was still the biggest band in the world. Everyone at my junior high who played guitar learned how to play 'Rape Me' or 'Smells like Teen Spirit' as their first song" says Sands. The first song sands learned on guitar was Nirvana's "About a Girl," and the first album she bought was Hole's "Live Through This."

"One of my first jobs, actually, was making burnt cd’s for a guy who sold them at the alley, and he made me copy Trina cd’s, ten at a time. She had songs on there like 'Nasty Bitch,' things like that, and I just loved it! But it was like a guilty pleasure, 'cause I was still a rock kid."  - Drew Arriola-Sands

By her early twenties, she started her first real band, The Glitter Path; Sands describes it as something like Daniel Johnston, the schizophrenic outsider musician, mixed with Patsy Cline - extremely emotional, "lying across the road, ready to die type of music." It didn't fit in in the "very straight, very cis, surf rock-indie" backyard scene, says Sands. She can't remember the band playing more than two or three shows, anywhere, but she says she doesn't hold any grudges.

The Glitter Path's "Wear a Wig"

We look at another photo of Sands from her Glitter Path days. She points out the increasing number of women’s accessories she was wearing at the time. She was starting to feel a change coming.

"I was in a relationship in 2013 with an artist, but I was male presenting, and I had these feelings of identity and gender, and I expressed them to him, and he accepted them," Sands says,  "but didn’t know how to deal with me and I didn’t know how to deal with myself." Sands boyfriend broke up with her, and she reevaluated her emotional state. "My mental health was not going to get better if I did not come out [as a trans person]," she decided.

She had a much easier time dating after transitioning, and one chance hook-up set Sands down a new musical road.

"So this guy I was hooking up with at the time would play the Damned in the room while we were hooking up. I had a guitar in the room, and he didn’t know I played music and said, 'Do you play guitar?' I said, 'Yeah.' He said, 'Well, you should start a band, like the Damned, and play guitar. It’d be good, looking the way you do, and wear ball gowns.'” - Drew Arriola-Sands

Sands started Trap Girl, not as guitarist, but as lead singer, in 2014.

The early shows were backyard gigs in South Central. Songs like “Dead Men Don’t Rape” went over well, but Sands wasn’t out as a trans performer yet. Maybe people could read between the lines though, with a name like Trap Girl. Sands offers a few definitions for Trap Girls/Trap Queens (though she has never settled on just one).

• A woman who helps out a "trap lord," or drug dealer
• A very convincing transvestite
• A girl trapped in a man's body

Throughout 2015, Trap Girl built their following Downtown and on the Eastside, with Sands finally out as a trans artist.

Trap Girl live at Xicana PUNK Night

"I started this band alone," explains Sands. "I didn’t know any queer people, I didn’t know any trans people, I didn’t know who was gonna help this band. Who was gonna give us a shot? So, I was ready to defend this band, even though there was no one defend it from."

Rather, Trap Girl were embraced and found sisterhood in bands like Sister Mantos and Yaawn. In 2016, Sands took it a step further and organized the first annual Transgress Fest (at the Santa Ana LGBT Center), for trans performers. "We had people as young as twelve to people as old as sixty in the audience," she says. "We had a huge turnout. I never expected that."

Transgress Fest is coming back in November. In the meantime, Trap Girl are getting ready to release their second EP, "The Black Market." The title track grapples with the question of whether or not a trans person needs surgery.

"Being a woman doesn’t mean you have to look like a woman. I didn’t know any trans people at all before I transitioned, so automatically, my idea was to think that I needed to present as feminine to be accepted as a trans person, but little did I know, that that’s the last thing you need to be a trans person. Not all people can pass, and that’s ok." - Drew Arriola-Sands

Sands says the takeaway from "The Black Market" is not to risk your life with black market cosmetic procedures. "These girls are killing themselves to achieve their looks," says Sands. "They’re getting it offline [sic], off Craigslist. You know, they go to someone’s basement and get their ass injected with cement, and then they go home and get a blood clot in their lungs, and they die." "The Black Market" EP is due for release this summer.

Trap Girl is singer Drew Arriola-Sands, bassist Ibette Ortiz, drummer Jorge Reveles, and guitarist Estevan Moreno.

Many people turn to the Internet to find a Mr. or Ms. Right. But lemurs just give their potential partners a sniff. A study of lemur scents has found that an individual’s distinctive body odor reflects genetic differences in their immune system, and that other lemurs can detect these differences by smell. From just one whiff, these primates can tell which prospective partners have immune genes different from their own. The ability to sniff out mates with different immune genes could make their offspring’s immune systems more diverse and able to fight more pathogens. Shown here: Fritz the ring-tailed lemur sniffs a tree for traces of other lemurs’ scents.

A new study estimates that life expectancy in the U.S. decreased by nearly two years between 2018 and 2020, largely due to the COVID-19 pandemic. And the declines were most pronounced among minority groups, including Black and Hispanic people.

In 2018, average life expectancy in the U.S. was about 79 years (78.7). It declined to about 77 years (76.9) by the end of 2020, according to a new study published in the British Medical Journal.

"We have not seen a decrease like this since World War II. It's a horrific decrease in life expectancy," said Steven Woolf of the Virginia Commonwealth University School of Medicine and an author of the study released on Wednesday. (The study is based on data from the National Center for Health Statistics and includes simulated estimates for 2020.)

Beyond the more than 600,000 deaths in the U.S. directly from the coronavirus, other factors play into the decreased longevity, including "disruptions in health care, disruptions in chronic disease management, and behavioral health crisis, where people struggling with addiction disorders or depression might not have gotten the help that they needed," Woolf said.

The lack of access to care and other pandemic-related disruptions hit some Americans much harder than others. And it's been well documented that the death rate for Black Americans was twice as high compared with white Americans.

The disparity is reflected in the new longevity estimates. "African Americans saw their life expectancy decrease by 3.3 years and Hispanic Americans saw their life expectancy decrease by 3.9 years," Woolf noted.

"These are massive numbers," Woolf said, that reflect the systemic inequalities that long predate the pandemic.

"It is impossible to look at these findings and not see a reflection of the systemic racism in the U.S.," Lesley Curtis, chair of the Department of Population Health Sciences at Duke University School of Medicine, told NPR.

"This study further destroys the myth that the United States is the healthiest place in the world to live," Dr. Richard Besser, president of the Robert Wood Johnson Foundation (an NPR funder), said in an email.

He said wide differences in life expectancy rates were evident before COVID-19. "For example, life expectancy in Princeton, NJ—a predominantly White community—is 14 years higher than Trenton, NJ, a predominantly Black and Latino city only 14 miles away," Besser said.

Life expectancy in the U.S. had already been declining — albeit slowly — in the years leading up to the pandemic. And the U.S. has been losing ground compared with other wealthy countries, said Magali Barbieri of the University of California, Berkeley, in an editorial published alongside the new study.

The study estimates that the decline in life expectancy was .22 years (or about one-fifth of a year) in a group of 16 peer countries (including Austria, Finland, France, Israel, the Netherlands and the United Kingdom) compared with the nearly two-year decline in the United States.

"The U.S. disadvantage in mortality compared with other high income democracies in 2020 is neither new nor sudden," Barbieri wrote. It appears the pandemic has magnified existing vulnerabilities in U.S. society, she added.

"The range of factors that play into this include income inequality, the social safety net, as well as racial inequality and access to health care," Duke's Curtis said.

So, what's the prognosis going forward in the United States? "I think life expectancy will rebound," Woolf of Virginia Commonwealth said.

But it's unlikely that the U.S. is on course to reverse the trend entirely.

"The U.S. has some of the best hospitals and some of the greatest scientists. But other countries do far better in getting quality medical care to their population," Woolf said. "We have big gaps in getting care to people who need it most, when they need it most."

Despite the racial reckoning going on in America right now, and despite the fact that attitudes towards race, inclusion and representation are different now than they were 30 years ago, new research from UC Berkeley shows that a large majority of American metro areas are more segregated now than they were in 1990. The new report from Berkeley’s Institute covers a number of topic areas, but among the key findings were from the national segregation report component of the project, which found Los Angeles to be the sixth-most segregated metro area with more than 200,000 people.

Today on AirTalk, we’ll talk with the lead researcher on the new report and a local historian to talk about how we see the findings of the report play out in Southern California.

Normal is not easily defined.

The past 15 months, though, have certainly been anything but.

Americans are starting to believe a "sense of normal" is approaching fairly soon, however, according to a new NPR/PBS NewsHour/Marist survey. The poll also found that with the coronavirus receding in this country, mask-wearing is declining and Americans are going out more. But they remain cautious about being in large crowds.

As the country continues to open up, more focus turns to the economy, which cratered during the beginning of the pandemic last year. And Americans are split by race, gender and politics on whether President Biden's ambitious policies are helping or not.

Race, gender, party divides on Biden and the economy

Three months ago, in a similar survey, 49% of adults said the president's policies were strengthening the economy, while 44% said they were weakening it.

Now, that's declined a net of 6 points, as 44% of respondents in the new poll say Biden's policies have strengthened the economy and 45% say the opposite. The percentage who were unsure also jumped 4 points. It's all a little bit of a warning sign for Biden, as he pushes for two large — and expensive — spending packages.

There are significant splits by race and gender:

• Just 39% of whites said Biden's policies have strengthened the economy, but 52% of people of color say they have.
• 54% of independent men say his policies have weakened the economy, while 56% of independent women say they've strengthened it. 
• 45% of white male college grads say Biden has strengthened the economy, but a significantly higher 64% of white women with college degrees said so.

Inflation vs. wages by party

A quarter of Americans rank inflation as the U.S. economy's top concern. That's followed by wages, unemployment, housing costs, labor shortages, gas prices and interest rates.

But there's a sharp political divide on the question. Republicans and independents rank inflation as their top concern, while for Democrats, it was wages. Just 4% of Republicans said wages were their top concern.

Return to "normal"

Americans are growing increasingly optimistic about when life will return to a "sense of normal," as the survey labels it.

In April, three-quarters of Americans said they believe it will take six months or more. Now, it's just half. About a quarter (27%) say it will be less than six months, up from 15% two months ago.

People are also growing more comfortable doing certain things, saying they're:

• dining out at restaurants (78%) and 
• visiting unvaccinated friends and family (75%).

But they are not as comfortable doing others:

• almost 7-in-10 are not going out to bars; 
• about two-thirds are not attending live concerts or sporting events (65%);
• and a majority have also not resumed going to in-person religious services (54%).

COVID-19 vaccines and going back to work

While half say they are concerned about another coronavirus surge, almost 9-in-10 U.S. adults with jobs say they are at least somewhat comfortable returning to work.

Notably, a majority (57%) of those with jobs do not believe employers should require COVID-19 vaccines as a condition to return to in-person work.

More than a quarter of Americans say they will not get vaccinated. The most resistant to getting vaccinated continue to be supporters of former President Donald Trump. Half of them say they won't get the shot, the highest of any group surveyed. Trump has touted the vaccine and got it himself.

Since Centers for Disease Control and Prevention guidelines came out, noting that Americans who have been vaccinated can largely set masks aside, there's been a double-digit decline in those saying they wear a mask even when it's not required.

There's also been a double-digit increase in those saying they generally do not wear a mask. In May, 49% said they wore masks even when it was not required. Now, that's just 36%.

One-in-five said they generally do not wear masks. Two months ago, it was less than one-in-10.

Affordability, not coronavirus, limiting vacations

Speaking of getting back to normal, a majority of Americans say they plan to take a vacation this summer.

But of the significant minority (45%) who say they aren't taking one, almost three times as many cited affordability (35%) as the main reason for not going, as opposed to concerns about COVID-19 (12%).

Methodology: The poll of 1,115 U.S. adults was conducted using live telephone interviewers from June 22 through June 29. Survey questions were available in English or Spanish. The full sample has a margin of error of plus or minus 3.7 percentage points, with larger margins of error for smaller group subsets.

A National Science Foundation-funded research has discovered the root cause of why lithium metal batteries fail -- bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access. The discovery challenges the conventional belief that lithium metal batteries fail because of the growth of a layer, called the solid electrolyte interphase (SEI), between the lithium anode and the electrolyte. The researchers made their discovery by developing a technique to measure the amounts of inactive lithium species on the anode -- a first in the field of battery research -- and studying their micro- and nanostructures. The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market.

A new study shows that the West Antarctic Peninsula is experiencing some of the most rapid climate change on Earth, featuring dramatic increases in temperatures, retreats in glaciers and declines in sea ice. The Southern Ocean absorbs nearly half of the carbon dioxide -- the key greenhouse gas linked to climate change -- that is absorbed by all the world's oceans. The study tapped an unprecedented 25 years of oceanographic measurements in the Southern Ocean and highlights the need for more monitoring in the region. The research revealed that carbon dioxide absorption by surface waters off the West Antarctic Peninsula is linked to the stability of the upper ocean, along with the amount and type of algae present. A stable upper ocean provides algae with ideal growing conditions. During photosynthesis, algae remove carbon dioxide from the surface ocean, which in turn draws carbon dioxide out of the atmosphere. From 1993 to 2017, changes in sea ice dynamics off the West Antarctic Peninsula stabilized the upper ocean, resulting in greater algal concentrations and a shift in the mix of algal species. That's led to a nearly five-fold increase in carbon dioxide absorption during the summertime. The research also found a strong north-south difference in the trend of carbon dioxide absorption. The southern portion of the peninsula, which to date has been less impacted by climate change, experienced the most dramatic increase in carbon dioxide absorption, demonstrating the poleward progression of climate change in the region.

On August 17, 2017, scientists made history with the first direct observation of a merger between two neutron stars. It was the first cosmic event detected in both gravitational waves and the entire spectrum of light, from gamma rays to radio emissions. The impact also created a kilonova -- a turbocharged explosion that instantly forged several hundred planets’ worth of gold and platinum. The observations provided the first compelling evidence that kilonovae produce large quantities of heavy metals, a finding long predicted by theory. Astronomers suspect that all of the gold and platinum on Earth formed as a result of ancient kilonovae created during neutron star collisions. Based on data from the 2017 event, first spotted by the Laser Interferometer Gravitational-wave Observatory (LIGO), astronomers began to adjust their assumptions of how a kilonova should appear to Earth-bound observers. A team of scientists reexamined data from a gamma-ray burst spotted in August 2016 and found new evidence for a kilonova that went unnoticed during the initial observations.

What do Janet Jackson, Ira Glass, Kermit the Frog, Nas and Louis Armstrong have in common?

These musicians, interviewers, and frogs are behind songs and other recordings to be inducted into the Library of Congress's National Recording Registry on Wednesday.

The Library of Congress announced the 25 titles picked this year are considered "audio treasures worthy of preservation" based on their cultural, historical, or aesthetic importance to the nation's heritage.

Janet Jackson's album "Rhythm Nation 1814;" Louis Armstrong's performance of "When the Saints Go Marching In;" Patti Labelle's song "Lady Marmalade;" Nas' record "Illmatic," Kool & the Gang's "Celebration;" and Kermit the Frog's "The Rainbow Connection" are now part of the collection of more than 550 other titles.

"The National Recording Registry will preserve our history through these vibrant recordings of music and voices that have reflected our humanity and shaped our culture from the past 143 years," Librarian of Congress Carla Hayden said in a statement Wednesday.

The recordings, stretching from 1878 to 2008, were chosen out of 900 nominations from the public, Hayden said.

"This American Life" is the first podcast to join the registry. The 2008 episode co-produced with NPR News telling the story of the subprime mortgage crisis will be added to the collection.

"When we put this out as a podcast, turning a radio show into a podcast, we did literally nothing to accommodate it," host Ira Glass said in a statement shared by the Library of Congress. "And my theory is that podcasting is most powerful for the same reason that radio is the most powerful. That is, when you have a medium where you're not seeing people, there's just an intimacy to hearing somebody's voice."

The inclusion of Kermit the Frog's "The Rainbow Connection" deeply touched the Muppet.

"Well, gee, it's an amazing feeling to officially become part of our nation's history," Kermit said in a statement. "It's a great honor. And I am thrilled — I am thrilled! — to be the first frog on the list!"

The song was included in the 1979 "The Muppet Movie" performed by Jim Henson as Kermit the Frog, and written by Paul Williams and Kenneth Ascher.

Williams said the song is about the "immense power of faith."

"We don't know how it works, but we believe that it does," Williams said. "Sometimes the questions are more beautiful than the answers."

Under the terms of the National Recording Preservation Act of 2000, the Librarian of Congress selects 25 titles each year that are at least 10 years old.

The Biden administration plans to open the California coast to offshore wind development, ending a long-running stalemate with the Department of Defense that has been the biggest barrier to building wind power along the Pacific Coast.

The move adds momentum to the administration's goal of reaching 100% carbon-free electricity by 2035, coming just weeks after the country's first large-scale offshore wind farm was approved off the coast of New England. Today, the country has just a handful of offshore wind turbines in the Atlantic Ocean, with around a dozen wind farms being developed in federal waters off the East Coast.

"It's an announcement that will set the stage for the long term development of clean energy and the growth of a brand new made-in-America industry," says national climate adviser Gina McCarthy. "Now we're thinking big and thinking bold."

The agreement identifies two sites off Central and Northern California with the potential to install massive floating wind turbines that could produce 4.6 gigawatts of electricity, enough to power 1.6 million homes.

Interest in offshore wind on the West Coast has grown for years, especially with California's own ambitious goal to cut greenhouse gas emissions. The deep waters off the coast have the potential to produce a significant amount of energy.

But the Defense Department has largely objected to the idea, since the Navy and Air Force use the area for training and testing operations. In response to the growing interest, the Navy released a map in 2017 putting large swaths of California waters off limits.

In 2018, the federal Bureau of Ocean Energy Management solicited interest from wind developers. But negotiations with the Department of Defense have been slow going ever since, effectively blocking wind development off California.

Tuesday's announcement outlines a compromise for a 399-square-mile area off Morro Bay, a site that's appealing to renewable energy companies because of existing transmission lines nearby that once service a retired power plant. It also identifies a location off Humboldt County in Northern California.

"It's our view that the world faces a grave and growing climate crisis," says Dr. Colin Kahl, undersecretary of defense for policy. "Climate change is both a threat to the Department of Defense's operations around the world and an existential challenge to our ability to maintain resilience here at home."

Another key site, just offshore from the Diablo Canyon nuclear power plant, was not included in Tuesday's deal. California's last-remaining nuclear plant is scheduled to completely close by 2025, freeing up more potential transmission lines for offshore wind.

The Biden administration has set a goal of jump-starting the country's offshore wind sector with 30 gigawatts of projects by 2030. Those wind farms will foster tens of thousands of jobs, according to the White House, between renewable energy installers, manufacturers and steelworkers.

"This is a major breakthrough — a major advancement that will allow California to start planning for its carbon-free electricity goals with offshore wind firmly in the picture," says Nancy Rader of the California Wind Energy Association, who also pointed to the challenges. "Offshore wind development off the coast at Morro Bay and Humboldt will require a major port facility in each area to construct the floating platforms and assemble the turbines that will require continued proactive planning by the state and federal governments."

Still, the areas identified in the agreement may not be enough for hitting the administration's clean electricity goal, as well as California's. The state is planning to get 100% of its electricity from zero-emission sources by 2045. To reach that, renewable energy needs to triple statewide with offshore wind playing a key role, reaching 10 GW, according to a recent state analysis. Tuesday's deal could provide just half of that.

A potential lease auction for the offshore wind sites could be held in mid-2022. But the projects will still have to negotiate concerns about the potential impacts on California's fishing industry and shipping channels, as well as any environmental concerns about sensitive ecosystems.

"Far too many questions remain unanswered regarding potential impacts to marine life which is dependent on a healthy ecosystem," says Mike Conroy of the Pacific Coast Federation of Fishermen's Associations. "The fishing industry has been told these areas work best for offshore wind developers; but no one has asked us what areas would work best for us."

Two organizations filed a lawsuit against Indiana Gov. Eric Holcomb in an attempt to block the state's push to end pandemic unemployment benefits on June 19.

Indiana Legal Services, an organization providing free legal assistance, and the Concerned Clergy of Indianapolis filed the lawsuit on behalf of five unnamed plaintiffs who are set to lose their jobless benefits. The complaint was filed Monday in Marion County Superior Court.

This lawsuit may be the first of its kind that aims to stop states from ending these benefits earlier than Congress mandated.

The unemployment insurance program "has served as a vital lifeline for thousands of Hoosiers," the complaint, reviewed by NPR, says. "By prematurely deciding t0 stop administering these federal benefits, Indiana has violated the clear mandates 0f Indiana's unemployment statute—to secure all rights and benefits available for unemployed individuals."

Indiana is one of 25 Republican-led states that decided to end jobless aid in an effort to get people to return to work. Indiana and seven other states are set to end expanded unemployment benefits as soon as this weekend. This is despite Congress's authorization for extra payments until early September.

Those benefits include the extra $300 a week in federal aid and the special pandemic program for gig workers that allows them to receive jobless benefits. Ordinarily, independent contractors wouldn't be eligible.

Plaintiffs, as well as many other Indiana residents, rely entirely on the unemployment benefits to pay for food and rent and to care for their families, the complaint alleges.

Attorneys in this case are requesting the judge approve a preliminary injunction that would allow people to receive their benefits while the case continues.

Holcomb says it's time to get back to work

Holcomb told The Indianapolis Star that people no longer need unemployment benefits as the state has a plethora of jobs open.

"Eliminating these pandemic programs will not be a silver bullet for employers to find employees, but we currently have about 116,000 available jobs in the state that need filled now," he said.

According to the governor's office, Indiana's unemployment rate has recovered to 3.9% after climbing to 17% at the height of the pandemic.

The lawsuit challenges Holcomb's assertion.

Each of the five plaintiffs say they are unable to return to work due to lingering injuries or disability, health conditions that put them at risk for COVID-19 exposure, dependent children at home and no childcare available, or no positions that are available in their career field.

Workers of color feel the loss of unemployment the most

The National Employment Law Project says ending these jobless benefits early threatens the livelihoods of workers of color the most.

Millions of Americans still heavily rely on jobless aid as the country slowly reopens from pandemic-induced lockdowns, according to the organization.

As of May 22, more than 15.3 million people still needed some form of unemployment benefit—nearly twice the number who received payments when the aid programs began in late March 2020, NELP said.

According to its analysis, over 46% of unemployment insurance recipients in the states ending the programs early are people of color.

"The brunt of the impact will be felt by Black, Latinx, Indigenous, and other people of color," NELP says.
