A Virginia Commonwealth University researcher has developed an alternative method of producing semiconductor materials that is environmentally friendly. Semiconductors are crucial to modern electronics and displays, but they are constructed from toxic solvents. They also are created at high temperatures and pressures, resulting in both environmental damage and high production costs. The new technique has been introduced by Leah Spangler, Ph.D., assistant professor in the VCU College of Engineering’s Department of Chemical and Life Science Engineering, and Michael Hecht, a professor of chemistry at Princeton University. It demonstrates an alternative method to produce semiconductor materials called quantum dots using proteins at room temperature in water, resulting in a more environmentally friendly synthesis method. “This research uses de novo proteins, which are not taken from natural organisms but instead made by design for specific purposes,” Spangler said. “Therefore, this work shows that protein design can be leveraged to control material properties, creating an exciting new direction to explore for future research.” This work builds on natural examples of proteins creating materials, known as biomineralization. But this is the first example that uses de novo proteins made by design to control the synthesis of quantum dots. The study, “De Novo Proteins Template the Formation of Semiconductor Quantum Dots,” was published in the journal ACS Central Science. The work is related to a recent Department of Defense grant to Spangler to test an eco-friendly approach for separating rare earth elements into a refined final product using de novo proteins.

Immigrants in the United States earn 10.6% less than similarly educated U.S.-born workers, largely because they are concentrated in lower-paying industries, occupations and companies, according to a major new study published July 16 in Nature, co-authored by a University of Massachusetts Amherst sociologist who studies equal opportunity in employment. The research—one of the most comprehensive global comparisons of immigrant labor market integration to date—analyzes linked employer-employee data from over 13 million people across nine advanced economies in Europe and North America. The U.S. results, drawn from a unique combination of Census Bureau, earnings and employer data, reveal that only about one-quarter of the wage gap is due to pay inequality within the same job and company. Instead, the majority stems from structural barriers that limit immigrants’ access to better-paying workplaces. “These findings are important because they show that most of the immigrant wage gap isn’t about being paid less for the same work—it’s about not getting into the highest-paying jobs and firms in the first place,” says Donald Tomaskovic-Devey, professor of sociology and founding director of the Center for Employment Equity at UMass Amherst Key U.S. Findings First-generation immigrants with legal status in the U.S. earn 10.6% less than comparable native-born workers. 3.4%, a third of that gap, is attributable to unequal pay for the same job at the same employer. No data was available on second-generation immigrants in the U.S., but other countries showed persistent but smaller gaps into the next generation. The study suggests that efforts to close immigrant wage gaps should focus on increasing immigrants’ access to better jobs and firms. Promising approaches include: Language and skills training Recognition of foreign credentials Access to professional networks Employer anti-bias interventions “Improving job access is essential,” says co-author Andrew Penner, professor of sociology at the University of California, Irvine. “This means addressing the barriers that keep immigrants out of the highest-paying firms and occupations.” As of 2023, immigrants constituted approximately 14% of the U.S. population, totaling over 47 million people. There are approximately 1 million new long-term permanent residents annually. U.S. immigration policy encompasses diverse pathways, including family-based migration, employment-based visas, the Diversity Visa Lottery and humanitarian protection. Immigration has been a defining feature of the U.S. population since its founding, with distinct waves shaped by economic needs, political developments and global conflicts. “For almost 250 years, we have been a nation of immigrants, and this pay gap indicates that we can do more as a country to help people following the paths of our forebears realize the American dream,” Tomaskovic-Devey adds. Global Comparison The study includes 13.5 million individuals in nine immigrant-receiving countries: the U.S., Canada, France, Germany, Denmark, Netherlands, Norway, Spain and Sweden. The U.S. had one of the smallest pay gaps (10.6%) among the nine countries studied. By contrast, Canada showed a 27.5% gap and Spain a 29.3% gap. The most favorable outcomes for immigrants were in Sweden (7% gap) and Denmark (9.2%). The authors identify two main sources of the immigrant-native pay gap: Sorting—Immigrants are more likely to work in lower-paying industries, occupations and firms. Within-job inequality—In all countries immigrants are paid less than natives doing the same job for the same employer, but these gaps are relatively small. Across the nine countries, three-quarters of the 17.9% average wage gap for immigrants was due to sorting; just one-quarter stemmed from unequal pay within jobs. In the U.S., this pattern was consistent: structural job access—not wage discrimination—was the dominant force. The study also exposes persistent disadvantages for immigrants from certain world regions, including Sub-Saharan Africa, Latin America and the Middle East. Across all countries, immigrants from these regions faced larger wage gaps than immigrants from Western or Asian countries. The international research is the latest in a series of high-profile publications from a team spanning over a dozen countries in North America and Europe that has been investigating the dynamics of workplace earnings distributions for the last decade.
Pets and the Texas floods: Owners faced difficult decisions and loss during and after disaster
One of the more overlooked aspects of any disaster is the loss of pets. Many of them become separated from their owners, are badly injured or perish as the result of a hurricane, flood, earthquake or other major event. This was the case in the recent flooding of the Guadalupe River in central Texas, said Sarah DeYoung, core faculty with the University of Delaware's Disaster Research Center. DeYoung can talk about the following aspects related to the tragedy: • The decisions that people have to make during evacuation, particularly for those with companion animals. • The amount of horses along the Guadalupe River, which could be found at the camps and recreation areas. • Pets that go missing after a flash flood, and the role that key organizations play in response and tracking and managing logistics. • The psychological impact on people whose pets were injured or died, who are mourning and making memorials. DeYoung can also discuss maternal and child health in crisis and disaster settings with a focus on infant feeding in emergencies.

What X chief executive's sudden exit means for the future of the social media giant
A sudden CEO departure almost always causes shockwaves. But the unexpected July 9 exit of X chief executive Linda Yaccarino after just two years – especially without a meaningful explanation – suggests instability or deeper dysfunction, says Lawrence Cunningham, director of the University of Delaware's Weinberg Center for Corporate Governance. Cunningham said the immediate questions are what was the succession plan, and is it now being executed? "Or was there no plan, which itself is a governance failure? Boards have a duty to prepare for transitions, especially in volatile environments. If succession planning was absent or inadequate, more departures may follow," he said. Cunningham can discuss the following topics in regards to Yaccarino's departure: • What a short CEO tenure signals about board oversight and strategic misalignment. • The role of succession planning – and what it means if none was in place. • Why reputational risk and cultural tone at the top matter in retaining leadership. • How boards should respond to external controversies affecting company values.

L to R: Professor Helen Wood, Annika Allen and Nadia Afiari (Image: Simon Roberts Photography) Aston University’s Professor Helen Wood led the research for Black Leaders in TV, a company championing Black TV professionals Black in Focus is the first report of its kind and highlights the prevalence, with 92% of respondents reporting prejudicial or discriminatory experiences Recommendations for improvements include mid-career support, changing how Black stories are commissioned and tackling racism and bullying. Black television professionals in the UK’s television industry continue to face persistent barriers to career progression, with progress towards equity and inclusion very slow, according to new research led by Aston University academics. The report, Black in Focus, was produced in partnership with Black Leaders in TV, a company set up to champion Black professionals in the UK television and content creation industry, committed to bridging the representation gap and creating a more inclusive and innovative industry. The research group was led by Professor Helen Wood, a professor of media and cultural studies at Aston University. It also included Aston University’s Dr Killian Mullen and Dr Priya Sharma, alongside Dr Jack Newsinger, associate professor in cultural industries and media at the University of Nottingham. The researchers surveyed 164 Black mid-career television professionals to learn about their experiences. While entry-level diversity efforts have sparked positive change, the researchers say that respondents generally see this as performative, with little genuine progress at mid and senior levels. Of those surveyed, 92% reported experienced microaggressions at work, defined as subtle, often unintentional, comments or actions that express prejudice or discrimination towards them, such as being mistaken for a taxi driver or colleagues continually mispronouncing a name. 80% stated that their careers in television have negatively impacted wellbeing. Almost three-quarters (74%) of respondents said they had been ignored or excluded at work One of the biggest problems highlighted is a persistent ‘club’ culture with career progression often based on informal networks and hires. 91% of the survey respondents reported having no friends or family in the industry, blocking wider access and opportunity. Many Black television professionals still report being labelled as ‘diversity hires’, which negatively impacts their confidence and feeling of belonging in the industry. Black-Caribbean respondents and those from working-class backgrounds report heightened feelings of exclusion. Another major problem found by the report is in programme commissioning, with Black stories often viewed as commercially risky, leading to missed opportunities for richer, more authentic storytelling. The recommendations for improvement are grouped into four categories - breaking the mid-career bottleneck, commission, diversity initiatives, and racism, bullying and inclusion failures. To help with career bottlenecks, the authors’ suggestions include developing a national fellowship scheme to offer structured leadership training, shadowing, and commissioning exposure for Black professionals, setting up a centralised database for Black talent and supporting Black creatives though industry showcases. The television industry could tackle the problems with commissioning for example by incentivising Black-led narratives and requiring commissioning teams to complete anti-bias training. Diversity initiatives should move away from entry-level programmes towards structural change. This includes moving away from informal, network-based recruitment to structured, clear processes, and formalising promotion pathways. The television industry can tackle racism and bullying through zero-tolerance harassment policies, independent reporting mechanisms and sanctions, inclusive leadership training and developing mental health resources specifically tailored to Black professionals. Professor Wood said: “We can hear the voices of frustration in this survey and the data is clear about the problems. It’s time for the industry to use this evidence to take the next steps to deliver real, systemic change.” Black Leaders in TV founders Nadia Afiari and Annika Allen Gray said: “The findings make clear that, for UK television to truly reflect its diverse audiences and unlock creative innovation, the industry must move beyond surface-level diversity efforts. There needs to be support in place for Black professionals, greater transparency in recruitment and progression, and a fundamental shift towards inclusive, equitable workplace cultures.” Visit https://www.aston.ac.uk/sites/default/files/2025-07/Black_in_Focus_report.pdf to read Black in Focus in full.
