Americans who say they expect to “never retire” are more likely than others to score low on a measure of financial knowledge, a new study shows.

In a national survey, 20% of those who missed all three financial knowledge questions said they expected they would never retire, compared to 12% who answered all questions correctly, who said they’d likely work well past retirement age.

The study also found that those who were overconfident in their financial knowledge (and those whose low levels of confidence reflected their knowledge) were more likely to say they would never retire.

The findings, combined with other research, suggest that many people who say they will never retire aren’t saying that because they love their jobs and want to continue working indefinitely, said Sherman Hanna, co-author of the study and professor of consumer sciences at The Ohio State University.

“If you’re not knowledgeable about finances, it suggests that you don’t know what your financial situation is, and you may have no idea when you can retire,” Hanna said.

“Saying they’re never going to retire may be for some people a way of saying they have failed to prepare for retirement.”

The study was published recently in the journal Financial Services Review.

The findings have important implications for the way experts evaluate how many Americans are adequately prepared for retirement.

Many analyses of the projected retirement adequacy of American workers assume that those saying they will never retire will end up retiring at about age 70. But in a previous study, Hanna and his colleagues found that many of these “never retire” workers will actually drop out of the workforce at a much younger age—suggesting they might stop earning a steady income before they’ve done enough to shore up their finances.

“It means our projections of the proportion of workers on track for an adequate retirement might be too optimistic,” Hanna said. “Many of those who say they will never retire may not know enough about their finances and are not working toward a financially successful retirement.”

The researchers used data from the 2016 and 2019 Surveys of Consumer Confidence, sponsored by the U.S. Federal Reserve Board. Their final sample included 4,607 households in which the head of the household was aged 35 to 60 and was working full time.

The three questions in the SCF that measured financial knowledge—called the “Big Three” by researchers—relate to compound interest, real rates of return and risk diversification.

Findings in this study found that the more questions participants got wrong, the more likely they were to say they expected to never retire.

The survey also asked participants to rate their own financial knowledge on a scale from 0 (no knowledge) to 10 (high knowledge).

Of those who said they weren’t financially knowledgeable (levels 0, 1 or 2), 30% expected to never retire, more than twice the 14% of those who believed they were very knowledgeable (levels 9 and 10).

The researchers also rated the financial confidence of participants—and whether they were overconfident or underconfident—by comparing their subjective ratings of their financial knowledge with their actual scores on the financial knowledge questions.

Results showed that 17% of those who were overconfident in their financial knowledge expected to never retire, higher than the 12% who had appropriately high confidence in their financial knowledge.

The findings suggest that financial planners, counselors and educators need to have a clear understanding of what it means when people say they expect to never retire, Hanna said.

“We need to evaluate those who don’t expect to retire to ensure they have the appropriate level of financial knowledge and confidence to help them make plans for their post-working life,” he said.

Other co-authors of the study were Zezhong Zhang and Lei Xu, both doctoral students at Ohio State.

A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells.

In their study, published in the journal Science Advances, the group introduced a specific microRNA cluster to panda fibroblasts to generate the iPSCs.

Over the past several years, stem cell biologists have been refining the process involved in converting cells known as fibroblasts into iPSCs as a prime part of regenerative medicine research. Such cells can be used to grow different kinds of cells, including those that can mature into organs and egg cells.

In recent years, conservationists have come to see the technology as a potential means to save endangered animals. To that end, iPSCs have been created for a rare zebra, the Tasmanian devil and the northern white rhino.

One thing that researchers on such projects have learned along the way is that the process of transforming fibroblasts to iPSCs is different for each species, which means that a new process is required to create iPSCs for each new animal. In this new effort, the research team has created a process for the giant panda.

The work started back in 2019, with the goal of creating iPSCs that could be used as precursors to male and female reproductive cells, helping to ensure the continued propagation of giant pandas. That effort led to the use of fibroblast skin cells to generate the desired iPSCs.

To get the fibroblasts to transform into iPSCs, the group introduced a specific type of microRNA cluster under special growing conditions that included molecules with just the right transcription factors for pandas.

Once they found a process that worked, the team refined it to make it more efficient. They have been testing their iPSCs to ensure that they can divide and form germ layers in usable ways—and from there, to grow into desired types of cells.

Engineers working on Google’s DeepMind project have announced the development of two new AI-based robot systems. One called ALOHA Unleashed was developed to advance the science of bi-arm manipulation. The other, called DemoStart, was developed to advance the capabilities of robot hands that have multiple fingers, joints, or sensors.

Details for ALOHA Unleashed have been posted on the DeepMind site and also on GitHub. Details for DemoStart have been posted on the arXiv preprint server.

As the research team notes, most robot hands developed to pick up and move objects generally act alone—they have no second hand to help them. In this new effort, the research team used AI technology to teach a robot to use both of its hands in conjunction to complete a “difficult” task, such as tying a shoe. The result is ALOHA Unleashed.

As the team also notes, the new system builds on ALOHA 2 and the ALOHA platform, which was developed at Stanford University for use in tele-operating applications. The new system improves dexterity and also allows two robot hands to become “aware” of one another as they work together on a common problem.

The robot hands were taught via demonstration to do tasks such as hanging a shirt or repairing a robot part. Afterward, diffusion methods were applied to give the robot hands some degree of prediction, helping them anticipate what the other would be doing.

The research team on DemoStart noted that complex dexterity in robots is going to mean using more fingers, joints and sensors than are currently used on most robot hands. To achieve that requires some degree of coordination between them.

Like the ALOHA Unleashed project, coordination required the introduction of AI into the learning process. With DemoStart, they used reinforcement learning to help the robot gain a sense of its abilities when given control of multiple arm, hand and finger joints, in addition to fingertips.

The approach involved giving the robot hands simple tasks and slowly ramping up the difficulty. They found they could teach a two-fingered robot with several joints and sensors to reorient a cube, tighten a nut and neaten a workspace.

Homicide is a leading cause of death among people 19 and younger in the United States, and firearms are used in a large proportion of these crimes. Although the homicide rate for this population declined in the 1990s and 2000s, it has increased every year since 2013, with a large spike during the COVID-19 pandemic.

Now, new research by Hannah Rochford, Ph.D., an assistant professor with the Texas A&M University School of Public Health, and two colleagues from the University of Iowa, provides insight into the characteristics of those who committed these crimes and their use of firearms from 1976 to 2020.

“The more national-level information we have about these perpetrators, the better we can develop comprehensive, evidence-based public health policies and prevention strategies,” Rochford said.

“Unfortunately, the data has lagged behind data that is known for most other public health challenges. For example, the National Violent Death Reporting System did not exist at all before 2003, did not include a majority of states until 2015, and still does not fully represent violent deaths in all states. This makes it difficult to learn from past trends, like the youth violence surge of the late 1980s and early 1990s.”

For their study, published in Injury Epidemiology, the researchers sought to fill these gaps by describing trends between 1976-2020 in perpetrator characteristics (sex, age and relationship to victim) and firearm presence by the age, sex, and race of U.S. homicide victims from birth to 19 years of age.

To do so, researchers applied the multiply-imputed version of the Federal Bureau of Investigation’s 1976–2020 Supplementary Homicide Reports (SHR).

“The unimputed SHR is limited by ‘unit missingness’ because not every law enforcement agency provides data for the reports every year, and ‘item missingness’ because some homicide incidents were missing case information,” Rochford said. “For example, more than one quarter of homicide incidents were missing information on the perpetrator’s age, sex and race.”

After stratifying the descriptive analyses by victim age group, sex, race and five-year time periods, the team found that family members were the most common perpetrator of infant and toddler (ages 0–4) and child (ages 5–12) homicides, and acquaintances accounted for the majority of adolescent (ages 13–19) homicides. One quarter of adolescent homicides with female victims were perpetrated by an intimate partner.

The team found there was a sustained increase in the proportion of homicides committed with a firearm. From 2016 to 2020, the proportion of homicides that involved firearms was an all-time high across the study period for three categories: infants and toddlers at 14.8%, children at 53.1%, and adolescents at 88.5%. Firearm homicide was particularly burdensome to Black pediatric victims, with Black infants and toddlers experiencing twice the burden as White infants and toddlers, for example.

“These differences appear to align with developmental changes in family dependency and interaction, peer and romantic relations, and age-related role independence,” Rochford said. “For example, adult female family members were responsible for more than a quarter of all infant and toddler homicides, but for less than 1% of adolescent homicides.”

Rochford said these findings indicate that policy interventions that improve family stability and well-being may be most effective at preventing infant, toddler and child homicides, and programs that target peer and community relationships, as well as policies that focus on firearm access, may be more crucial for preventing adolescent homicides.

Amazon MGM Studios will soon join the Motion Picture Association, the lobbying arm of Hollywood’s major studios announced.

The Seattle-based tech and retail giant—which distributes content via its theatrical arm, Amazon MGM, and its streaming service, Prime Video—will officially become the seventh member of the MPA on Oct. 1. Amazon backed the MPA’s anti-piracy efforts as a board member of the organization’s Alliance for Creativity and Entertainment.

Amazon is the second tech company after Netflix to gain MPA representation, a further sign of Hollywood’s ongoing effort to embrace new ways of reaching audiences—mainly streaming.

The MPA—which has historically advocated for traditional movie factories making features for theatrical release—made waves in 2019 when it added Netflix to its ranks.

In addition to Netflix, the organization currently reps Disney, Paramount, Sony, Universal and Warner Bros. Discovery.

“The MPA is the global voice for a growing and evolving industry, and welcoming Prime Video & Amazon MGM Studios to our ranks will broaden our collective policymaking and content protection efforts on behalf of our most innovative and creative companies,” said Charles Rivkin, chairman and chief executive of the MPA, in a statement.

“MPA studios fuel local economies, drive job creation, enrich cultures, and bolster communities everywhere they work. With Prime Video & Amazon MGM Studios among our roster of extraordinary members, the MPA will have an even larger voice for the world’s greatest storytellers.”

Amazon, which burst onto the movie scene in 2015 with Spike Lee’s “Chi-Raq,” is known for releasing titles such as “Manchester by the Sea,” “Challengers,” “American Fiction,” “Saltburn” and “One Night in Miami …”

The company cemented its presence in the motion picture space when it purchased legacy movie and TV studio MGM in 2022. Before the acquisition, MGM was a member of the MPA from 1928 until 2005.

“Amazon’s mission is to entertain customers around the world with compelling film and television,” said Mike Hopkins, head of Prime Video and Amazon MGM Studios, in a statement.

“In order to do that, we must support storytellers, while also helping to sustain a robust entertainment industry that works for both studios and our creative partners.”
