A century after Native Americans got the right to vote, they could put Trump or Harris over the top

RED SPRINGS, N.C. (AP) — Native American communities were decisive voting blocs in key states in 2020, and with the 2024 race remaining stubbornly close both campaigns have tried to mobilize Native voters in the final weeks of the presidential election.

But when it comes to messaging, the two campaigns could not be more different, many Native voters said. It’s been 100 years since Native Americans were given the right to vote, with the passage of the Snyder Act in 1924, and whichever campaign is able to harness their power in this election could swing some of the most hotly contested counties in the country.

In swing states like Arizona, North Carolina, Michigan, and Nevada, the candidates — particularly Vice President Kamala Harris — have been targeting Native Americans with radio ads and events on tribal lands featuring speakers like Bill Clinton and Donald Trump Jr.

Native American voters tend to favor Democrats, but they’re more likely to vote Republican than Latinos or African Americans, said Gabriel R. Sanchez, a senior fellow at the Brookings Institution. He said they are one of the least partisan and youngest voting demographics in the country, often motivated by issues that directly impact their communities, like land rights and environmental protections.

In 2020, the Biden administration campaigned in several tribal nations in critical states like Wisconsin and Arizona, and precincts on tribal lands there helped narrowly tip the election for the Democrats. “Arizona was kind of like a textbook example of what that could look like if you make those early investments,” Sanchez said.

As part of a $370 million ad campaign released this month, including on several reservations, Harris said the U.S. should honor treaty rights and uphold tribal sovereignty. Crystal Echo Hawk, CEO of Illuminative, a nonprofit that works to increase the visibility of Native Americans, said those commitments, along with the economy and environmental protections, are the top issues Native voters have identified in Illuminative’s surveys.

Echo Hawk said those investments could pay off again for the Democrats. “I haven’t seen the same kind of targeted messaging and outreach from the Trump campaign,” she said. Harris also stands to inherit some of the goodwill left from the administrations of Barack Obama and Joe Biden, she said.

Obama increased consultation with tribes on matters like land protections and criminal justice, and Biden appointed more than 80 Native Americans to senior administration roles.

“The minute that the announcement came that Harris was stepping into the race, you saw people organize overnight,” Echo Hawk said. And Trump, she said, will have to contend with his reduction of Bears Ears National Monument by 85% and his revival of the Keystone XL pipeline, both unpopular with Indigenous peoples. “I think a lot of these people remember that,” she said.

On Friday, Biden formally apologized for the country's support of Native American boarding schools and its legacy of abuse and cultural destruction. While seen as long overdue, it was met with praise from tribal leaders. On Saturday, vice presidential candidate and Minnesota Gov. Tim Walz will campaign in the Navajo Nation.

The Trump campaign hasn’t released ads targeting Native Americans, but U.S. Sen. Markwayne Mullin, a Republican from Oklahoma and a citizen of the Cherokee Nation, has stumped for the former president in Native communities in North Carolina, a swing state that was decided by less than one point in 2020.

On a crisp evening earlier this month, Mullin sat alongside Donald Trump Jr. and former Hawaii Rep. Tulsi Gabbard, a former Democrat who recently announced she is joining the Republican Party, on a small stage in front of several bales of hay to take questions from an audience of a couple hundred people. They discussed issues ranging from the economy to tribal self-determination.

The event took place on a small farm in Red Springs, North Carolina, part of the traditional homelands of Mullin’s ancestors and current home to the Lumbee Tribe, a state-recognized tribe with about 55,000 members.

The federal recognition of the Lumbee has been opposed by several tribal nations, including the nearby Eastern Band of Cherokee Indians and Mullin’s own tribe, the Cherokee Nation in Oklahoma. The Lumbee’s push for federal recognition has become a focal point for both campaigns and a rare issue where both parties agree. Last month, Trump said he would sign legislation granting federal recognition to the Lumbee. Harris called the Lumbee's tribal chairman last week to discuss the legislation.

“This is an injustice that needs to be fixed when it comes to Lumbees,” Mullin told the crowd. “This is absolutely absurd. It needs to be done. I was so proud to hear President Trump say that he would sign it.”

But Mullin soon touched on one of the many areas where the two candidates differ: energy policy. Highlighting the fact that he believed a second Trump term would mean a better economy and lower energy costs, Mullin laid out Trump’s policy in one recognizable term that was echoed by the audience, "Drill, baby, drill.”

Both the Biden and Trump administrations pushed to produce more oil and gas than ever, including extractive energy projects that were opposed by Indigenous peoples. However, Native leaders have expressed concern that Trump is more likely to further erode protections for tribal lands.

Mullin suggested that if tribal nations are truly sovereign, they should be able to conduct energy extraction without the burden of federal intervention. He said just like the Lumbee’s fight for federal recognition, the rights of tribes to govern their own lands is the victim of federal bureaucracy.

“Why is tribal land treated like public land?” Mullin asked, questioning why the federal government should have any oversight on tribal nations that extract natural resources on their own lands. “You have natural resources being pulled out of the ground right across the fence from reservations. You have private land owners that are extremely wealthy and you have people that are literally starving inside reservations,” he said, comparing some to third-world countries.

He promised Trump would have a deep understanding of tribal sovereignty.

That message resonated with Robert Chavis Jr., a physical education teacher and Army veteran who was at the rally and will be voting for Trump. Chavis, a member of the Lumbee Tribe, said tribal nations aren’t just governments, they’re businesses, and the U.S. is no different. “I feel like you don’t need a politician in there. We need a businessman to run the country like it should be.”

But other Lumbee voters aren’t as convinced. At her art gallery a few miles away in Pembroke, Janice Locklear said Trump promised he would federally recognize the Lumbee last time he was in office, and she had no reason to believe he could accomplish it this time. But looking broader than her community, she said what Trump did on Jan. 6, 2021, represents a nationwide threat to democracy.

“He thought he could actually be a dictator, go in there and take over. Even though he had lost the election; he knew he had lost the election. So what do you think he’ll do this time,” she said.

Locklear said as a woman of color, she trusts that Harris will have a deeper understanding of the unique challenges facing Native Americans. “I’m sure she’s had to face the same problems we face,” Locklear said. “Discrimination, I’m sure she’s faced it.”

A research team led by Professor Bonghoon Kim from DGIST’s Department of Robotics and Mechatronics Engineering has developed a “3D Smart Energy Device” that features both reversible heating and cooling capabilities. The team collaborated with Professor Bongjae Lee from KAIST’s Department of Mechanical Engineering and Professor Heon Lee from Korea University’s Department of Materials Science and Engineering. Their innovative device was officially recognized for its excellence and practicality through its selection as the cover article of the international journal Advanced Materials.

 

□ Heating and cooling account for approximately 50% of the global energy consumption, contributing significantly to environmental problems such as global warming and air pollution. In response, solar absorption and radiative cooling devices, which harness the sun and outdoor air as heat and cold sources, are gaining attention as eco-friendly and sustainable solutions. While various devices have been developed, many are limited in function, focusing solely on heating or cooling, and large-scale systems lack adjustability.

 

□ To address these limitations, Prof. Kim’s team created a “3D Smart Energy Device” that integrates reversible heating and cooling functions in a single device. The device operates on a unique mechanism: when the 3D structure opens through a mechanical peeling process, the lower layer—made of silicone elastomer and silver—is exposed to generate radiative cooling. When the structure closes, the surface coated with black paint absorbs solar heat, thus producing heating.

 

□ The team tested the device on multiple substrates, including skin, glass, steel, aluminum, copper, and polyimide, and demonstrated that adjusting the angle of the 3D structure enabled control over its heating and cooling performance. This ability to modulate thermal properties offers an efficient and promising solution for reducing energy consumption in temperature-controlled buildings and electronic devices at both macro and micro scales.

 

□  “We are honored to have our research selected for the cover article of such a prestigious journal,” said Professor Bonghoon Kim. “We aim to ensure that these findings are applied in industrial and building settings to help reduce energy consumption.”

 

□ This research was supported by the “Global Bioconvergence Interfacing Leading Research Center (ERC)” and the “Nano and Materials Technology Development Project” of the National Research Foundation of Korea. The results were published in Advanced Materials, where they were featured as the cover article.

Next-generation solar cells become more powerful with silver (Ag) doping technology!


Peer-Reviewed Publication

DGIST (Daegu Gyeongbuk Institute of Science and Technology)


 A team of senior researchers, including Kee-jeong Yang, Dae-hwan Kim, and Jin-gyu Kang from the Division of Energy & Environmental Technology, DGIST (President Kunwoo Lee), collaborated with Prof. Kim Jun-ho’s team from the Department of Physics, Incheon National University and Prof. Koo Sang-mo’s team from the Department of Electronic Materials Engineering to significantly improve the performance of kesterite (CZTSSe) thin-film solar cells in joint research. They developed a new method for doping silver (Ag) in solar cells to suppress defects that hinder cell performance and promote crystal growth, thereby dramatically increasing efficiency and paving the way for commercialization.

 

□ CZTSSe solar cells are composed of copper (Cu), zinc (Zn), tin (Sn), sulfur (S), and selenium (Se), and are gaining attention as a resource-abundant, low-cost, and eco-friendly solar cell technology. In particular, they have the advantage of being suitable for large-scale production and highly competitive in price because they use materials that are abundant in resources instead of the scarce metals used in conventional solar cells. However, conventional CZTSSe solar cells have low efficiency and high current losses due to electron-hole recombination, thus making them difficult to commercialize.

 

□ To address these issues, the research team employed a method of doping the solar cell precursor with Ag. Ag inhibits the loss of Sn and helps the materials mix better at low temperatures. This allows the crystals to grow larger and faster, reducing defects and improving the performance of the solar cell. In this study, they systematically analyzed how the placement of Ag at different locations in the precursor changes the defects and electron-hole recombination properties in the solar cell. The results indicate that Ag can significantly improve the performance of the solar cell by preventing Sn loss and maximizing the defect suppression effect.

 

□ Importantly, they also found that doping Ag in the wrong place actually interferes with the formation of Zn and Cu alloy, causing Zn to remain in the bulk and form defect clusters. This can lead to increased electron-hole recombination losses and degraded performance. From this, the research team offered an important insight: solar cell performance varies significantly depending on where Ag doping occurs.

 

□ Furthermore, the research team found that the liquid material formed by Ag doping promotes crystal growth, significantly improving the density and crystallinity of the absorber layer. This resulted in an improved energy band structure and fewer defects, ultimately allowing for smoother charge transport in the cell. These findings are expected to contribute significantly to the production of high-performance solar cells at low cost.

 

□ “In this study, we analyzed the effect of Ag doping, which had not been clearly identified before, process by process, and found that silver plays a role in suppressing tin loss and improving defects,” said Yang Kee-jeong, a senior researcher at the Division of Energy & Environmental Technology. “The results provide important insights into the design of silver-doped precursor structures to improve solar cell efficiency and are expected to contribute to the development of various solar cell technologies.”

 

□ The research was funded by the Ministry of Science and ICT’s Source Technology Development (Leapfrog Development of Carbon Neutral Technology) Program and the Future-Leading Specialization Research (Grand Challenge Research and Innovation Project (P-CoE)) Program. The paper was published online in the Energy & Environmental Energy (IF 32.4), a leading international journal in the field of energy.

Can mobile phone networks and Bluetooth technology help researchers improve animal tracking?



Wiley





Animal tracking studies for ecology and conservation all face technological limitations such as high costs or the need for tags to remain in close proximity to detectors. In research published in Methods in Ecology and Evolution, investigators describe a solution that can overcome many current limitations by employing the massive global network of personal mobile phones as gateways for tracking animals using Bluetooth low energy beacons.

In areas with medium to high density of people, these simple, lightweight, and inexpensive beacons can provide regular updates of position with a battery life of 1–3 years. Through field testing with sulphur-crested cockatoos and white-winged choughs, the beacons were capable of producing reliable high-frequency tracking data. The researchers were further able to demonstrate the potential of this method to study movements, home ranges, and social networks of urban living animals.

“We know that wildlife exhibit fascinating responses to urban habitats, and the ability to cheaply and reliably track animals will help to unlock many secrets of our urban animals,” said corresponding author Damien R. Farine, PhD, of the Australian National University.

In a first for the construction industry, researchers have developed a virtual vibration test rig (VTR) capable of simulating the fatigue life of dozer push arms with unprecedented accuracy. This cutting-edge solution offers a cost-effective and time-efficient alternative to traditional physical testing, allowing for more precise predictions of component durability. With the potential to streamline the entire testing process, this innovation could dramatically transform how construction machinery is evaluated and enhanced.

The working components of construction machinery, such as dozer push arms, face periodic conditions that result in fatigue damage over time. Continuous vibrations, tension, and impact forces accelerate wear, making precise fatigue analysis crucial to ensure reliability and performance. Traditional vibration test rigs are costly and time-consuming, often falling short in replicating real-world conditions. Due to these challenges, there is an urgent need for more efficient and accurate testing methods, prompting researchers to explore virtual test rigs to better analyze fatigue life.

This research (DOI: 10.1002/msd2.12125) was conducted by a team from Shandong University, in collaboration with Xiamen University and Kyunghee University, and was published on August 31, 2024, in the International Journal of Mechanical System Dynamics. The study presents a novel virtual vibration test rig (VTR) specifically designed for analyzing the fatigue life of dozer push arms. By utilizing simulation to generate highly accurate load spectra, this method bypasses the need for expensive physical rigs. The new approach is expected to revolutionize fatigue testing for construction machinery, offering faster and more reliable results.

The study focuses on the creation of a VTR that simulates the operational conditions of dozer push arms, enabling more precise fatigue life assessments. Using a virtual iteration technique, the VTR generates input signals that replicate real-world operating loads, iteratively fine-tuning them until they match actual working conditions. This approach addresses the shortcomings of traditional test rigs, which often struggle to reproduce the complex, dynamic behaviors of machinery components. By incorporating key data points such as strain, oil pressure, and cylinder stroke, the virtual VTR calculates accurate load spectra for fatigue analysis. The results show that this virtual method closely aligns with those obtained from physical experiments, reducing the testing time from hours to mere minutes and dramatically cutting costs. This innovation has wide-reaching implications for enhancing the reliability of product design while significantly lowering testing expenses across the construction machinery industry.

Prof. Xiangqian Zhu, a lead researcher from Shandong University, highlighted the transformative nature of the new system: "This VTR presents a groundbreaking alternative to conventional fatigue testing. Not only does it cut down on time and costs, but it also enhances the accuracy of fatigue life assessments. This method could reshape the way fatigue analysis is conducted in construction machinery, facilitating faster product development and improved reliability." Dr. Zhu also sees significant potential for the technology in various other sectors reliant on heavy machinery.

The VTR’s impact extends far beyond the construction industry. Sectors such as mining, agriculture, and defense stand to benefit from this innovative technology, which promises more efficient fatigue analysis for critical components. By enabling rapid design validation and reducing costs, the virtual rig offers manufacturers the ability to produce more durable and reliable machinery. The technology’s accuracy in simulating real-world conditions ensures that it will play a crucial role in enhancing both performance and safety, making machinery more cost-effective and resilient across multiple industries.

Political polarization poses health risks, new analysis concludes


Division stymies policymaking and implementation of healthcare programs, discourages individual action to take remedies, and fosters spread of misinformation


Peer-Reviewed Publication

New York University




News coverage of the 2024 election season has often centered on how partisan division has affected our politics. But a new analysis shows that political polarization also poses significant health risks—by obstructing the implementation of legislation and policies aimed at keeping Americans healthy, by discouraging individual action to address health needs, such as getting a flu shot, and by boosting the spread of misinformation that can reduce trust in health professionals. 

“Compared to other high-income countries, the United States has a disadvantage when it comes to the health of its citizens,” says Jay Van Bavel, a professor in New York University’s Department of Psychology and an author of the analysis, which appears in the journal Nature Medicine. “America’s growing political polarization is only exacerbating this shortcoming.”

But despite the challenges of political polarization, the analysis, which considered more than 100 experimental papers and reviews, pointed to potential ways to both minimize its impact on Americans’ health and promote health-care practices.

“Division is a major problem and the one real solution is trust. Public health agencies need to work with trusted voices and leaders, being proactive at sharing information, engaging questions, and not writing off concerns as irrelevant,” says Kai Ruggeri, a professor at Columbia University’s Mailman School of Public Health and one of the paper’s authors. “In a time when some people look less to doctors and more to prominent figures for information on decisions related to our health, the best steps involve engaging directly with those voices.” 

The analysis, which also included Eric Knowles, a professor in NYU’s Department of Psychology, and Shana Kushner Gadarian, a professor in Syracuse University’s Department of Political Science, considered Americans’ views of the opposite party over four decades, health-related behaviors during the coronavirus pandemic, and comparative data from other countries.

Over the past four decades, the paper’s authors note, partisan animosity has steadily increased in the US. By 2020, Americans were much more likely to say they “hate” the opposite party than they were to say they “love” their own party; by contrast, from 1980 through 2008, Americans were more likely to say they loved their own party than they were to say they hated the opposite party—though “party love” relative to “opposite party hate” has drawn closer virtually every year since 1980, becoming approximately even in 2012 and with “hate” surpassing “love” beginning in 2016.  

In their analysis and review of previous studies, the paper’s authors also examined a range of health-care related studies, which showed the following:

  • As individuals move further from the political center—in either direction—there is a deterioration in individual and public health, such as trust in medical expertise, participation in healthy behaviors, and preventive practices, ranging from healthy diets to vaccination. Notably, individuals who are more ideologically extreme than their state’s average voter have worse physical and mental health.
  • Polarization affects what health information people are willing to believe and shapes the relevant actions they are willing to take. This may mean disregarding accurate information or believing misinformation—depending on whether or not it comes from sources they are aligned with or disagree with.
  • Political leaders, inside and outside the US, may make public health worse by linking health behavior to partisan identity rather than medical needs or expert advice, thereby undercutting the role of expertise and ignoring approaches grounded in science, often leading to attacks on medical professionals and the healthcare system.
  • Republicans were less likely to enroll in marketplace insurance plans through the Patient Protection and Affordable Care Act (“Obamacare”) than were Democrats after most of its provisions took effect a decade ago. These differences have been linked to excess sick days from work, higher healthcare premiums, and higher mortality rates.
  • As policy polarization at the state level has increased over time, so has the difference in lifespan and health across states—Americans who live in states with more progressive social policies, such as generous Medicaid coverage, higher taxes on cigarettes, more economic support (e.g., a higher minimum wage), and more firearm regulations live longer than their counterparts in states that embrace more conservative policies. 
  • After the Trump administration and other Republican leaders expressed skepticism regarding COVID-19 prevention behaviors, partisan elites and news sources amplified this belief and polarized Republicans readily accepted it: large gaps in distancing and then vaccination rates between Republicans and Democrats widened during the pandemic, even as evidence mounted about the risks.
  • These differences were not limited to the US: a previous study of 23 European countries found that national levels of partisan polarization accounted for nearly 39% of the variation in vaccination levels.
  • Notably, another study of 67 countries found almost no correlation at all between left/right political ideology and support for public health recommendations, suggesting that polarization, rather than political ideology, was the greater risk factor to their citizens’ health.

The authors write that “although polarization is a risk factor for disease and mortality in a public health crisis, this outcome is not inevitable.” They point to a study comparing the US and Canada that suggests policy and leadership decisions can mitigate the potential harm from polarization. Although both nations were politically polarized at the onset of the pandemic, research found that political leaders in Canada took a different approach to those in the United States and also experienced a significantly lower level of illness and mortality. 

This and other studies point to specific approaches public officials and health-care professionals can take, which the Nature Medicine authors outline:

  • Highlight shared identities between public health officials and target populations—these can include shared partisan identities, nonpartisan identities, or national identities. 
  • Communicate information about how many people are following public health guidelines—instead of focusing on people who are failing to follow it.
  • Use trusted civic leaders—such as religious, athletic, and military spokespersons—to expand and supplement health messages from local and national leaders and reach diverse communities.
  • Debunk misleading or false information using fact checks, pre-bunking, and other validated strategies 

“Polarization is not only an American concern, but one that is increasing in many countries,” says Syracuse’s Gadarian. “This means we should be investing more in understanding and diminishing its impact on public health by encouraging collaborations between medical professionals and social scientists.”
