WEST LAFAYETTE, Ind. — Stress levels due to grocery prices are mixed, and most consumers are at least somewhat familiar with the concept of tariffs, according to the January issue of the  Consumer Food Insights Report (CFI).

The survey-based report out of Purdue University’s Center for Food Demand Analysis and Sustainability(CFDAS) assesses food spending, consumer satisfaction and values, support of agricultural and food policies, and trust in information sources. Purdue experts conducted and evaluated the survey, which included 1,200 consumers across the U.S.

The average grocery price stress level rating came in at 5.1 on a scale ranging from no stress at all (0) to extreme stress (10).

“Low- and middle-income households are more likely to report higher stress levels on this scale, with those earning less than $75,000 annually reporting an average rating of close to 6, whereas high-income earners reported an average rating around 4,” said the report’s lead author, Joseph Balagtas, professor of agricultural economics at Purdue and director of CFDAS.

New questions in the latest survey included a section that gauged consumer understanding of tariff policy. This included what they see as the costs and benefits of such policy and how they think tariffs affect food prices.

“The average rating among all consumers is 6.9 on a 0-10 scale, meaning consumers believe the government has moderate influence over the price of food,” Balagtas said. Further exploration of partisan differences in responses to this scale found that this belief is largely bipartisan.

CFDAS researchers gauged consumer understanding of the proposed tariffs as a policy tool and allowed them to express their opinion on the benefits and costs of such a policy. Most consumers — 80% — are at least somewhat familiar with the tariffs concept.

The survey presented consumers with an open response format rather than a list of potential benefits and costs of tariffs. “Around one-third of respondents say there are no benefits to tariffs while 20% are unsure,” Balagtas said. “Helping or protecting domestic industries was the most commonly cited benefit, followed by government revenue and trade fairness, leverage and regulation.”

A greater share of self-identified Democrats say there is no benefit to tariffs (42%) relative to independent (31%) and Republican consumers (21%). Many of the open responses mentioned cost of living and price increases. This was by far the most common theme, particularly in responses from Democratic consumers (63%). Fewer consumers believe there are no costs to tariffs (14%) and around 21% are unsure.

Most consumers (72%) think that tariffs raise prices to some degree. “How severe the increase also varies by political affiliation,” Balagtas said. “More than half of Democrats say they increase prices a lot relative to 35% of independents and 22% of Republicans.”

This month’s CFI Report includes a new section reporting on monthly consumer diet quality based on a nine-question diet assessment known as the Mini-EAT Tool. The questions asked consumers to report on consumption frequency of a variety of food groups such as fruits, vegetables, whole grains and sweets. Using these responses, CDFAS economists estimated diet quality.

“We estimate an average Mini-EAT score of 61.9 in January,” said Elijah Bryant, a survey research analyst at CFDAS and a co-author of the report. “This has remained relatively stable over time and translates to a diet quality classification of ‘intermediate.’ The threshold for an ‘unhealthy’ diet is scores less than 61, showing there’s plenty of room for improvement in terms of what we eat.”

Overall diet well-being remains stable, with two-thirds of American adults rating their diet as 7-10 (thriving) when asked where their diet fits on a scale from 0 (worst possible diet) to 10 (best possible diet).

Consumers in households on the Supplemental Nutrition Assistance Program (SNAP) rate their diet well-being comparably to those in non-SNAP households, Bryant said. However, a larger share of SNAP consumers put themselves in the “suffering” category (0-4 out of 10) on the diet well-being index.

“Food insecurity is higher among SNAP households compared to non-SNAP households. The gap is striking since SNAP benefits help alleviate food insecurity for low-income households,” Bryant said.

He points out, however, that previous research from the U.S. Department of Agriculture Economic Research Service found that many of those receiving SNAP benefits self-select into the program once they reach severe levels of food insecurity.

“So, while SNAP benefits are crucial for households in need, the positive effect on the food insecurity rate is likely not able to fully overcome the gap between SNAP and non-SNAP households,” Bryant said. 

On a scale from never (1) to always (5), consumers in SNAP households choose generic over name-brand food items more often (3.6) than non-SNAP consumers (3.2) when shopping for food. They also report checking labels more often.

“Since most of those receiving SNAP benefits are in low-income households, finding affordable food options such as generic and store brands can be crucial in ensuring that they get the proper amount of foods they need,” Bryant said.

Consumer estimates of food inflation over the past 12 months dropped to 5.2%, following a downward trend since late 2022. Expectations about future food inflation also dropped to 2.6%, just above the consumer price index food inflation rate of 2.5%. The USDA Economic Research Service recently updated its forecast for 2025 food inflation from the original 2.5% to 2.2%.

The Center for Food Demand Analysis and Sustainability is part of Purdue’s Next Moves in agriculture and food systems and uses innovative data analysis shared through user-friendly platforms to improve the food system. In addition to the Consumer Food Insights Report, the center offers a portfolio of online dashboards.

Pennington Biomedical researchers assemble comprehensive history of electronic health records and their role in medical research



Published in the Journal of Medical Internet Research, Dr. Yun Shen and Dr. Gang Hu explore 25 years of electronic health records’ secondary purpose - the interoperability with research



Pennington Biomedical Research Center




BATON ROUGE – Dr. Yun Shen and Dr. Gang Hu of Pennington Biomedical Research Center have recently published a piece in the Journal of Medical Internet Research, or JMIR. The study titled “Twenty-Five Years of Evolution and Hurdles in Electronic Health Records and Interoperability in Medical Research: Comprehensive Review,” explores how electronic health records’ use in medical research has evolved over the past 25 years.  Dr. Shen and Dr. Hu have extensive experience in working with electronic health records to study chronic diseases, population health trends, and predictive analytics. 

Primarily used for sharing patient data among healthcare providers, the two and a half decades of records have been funneled through big data analytics and the sophisticated applications of artificial intelligence, generating previously unseen patterns and driving medical innovations and insights.  

“Medical record keeping technically thousands of years ago as simple record keeping of treatments and symptoms, but modern medical record keeping first incorporated digitization as early as the 1960s,” said Dr. Shen, Assistant Professor of Chronic Disease Epidemiology Research at Pennington Biomedical. “Since that time, this method evolved from an effort to reduce physical storage to contributing to rich troves of data, which have informed and improved healthcare quality, safety and efficiency. Today, the big data generated from electronic medical records is supporting interoperability, seamless health information gathering and scanning of public health trends, even on a global scale.” 

A key aspect of electronic health record keeping is the separation of using the records for patient care and using them for research. Healthcare professions are instrumental in accurately documenting and gathering the data on the records, and may also input data related identifying information, patient demographics and billing information. A crucial step before such data is used for secondary research is deidentification, which involves removing or masking identifiable patient information to protect privacy. Data security and privacy concerns often influence how the collected information is used for research, and institutions have governing committees or boards to review research proposals for compliance. 

“Electronic Health Records have become a staple of the healthcare industry, and to explore the history of medical records and the growth of their application is crucial to understand how they can be used to advance medicine and improve outcomes,” said Dr. John Kirwan, Executive Director of Pennington Biomedical. “I congratulate Dr. Shen and Dr. Hu on the publication of this retrospective, and I look forward to what may result from it. We have teams of researchers here at Pennington Biomedical that pride themselves on pursuing new knowledge, including an exploration of new innovative AI tools that advance medical research." 

The study also includes a glimpse into the upcoming applications for electronic health records given its current trajectory, including precision medicine, social determinants of health, public health data, epidemiology data, data analytics, digital therapeutics, and further applications of artificial intelligence and wearable devices. Meanwhile, by engaging with healthcare institutions, policymakers, and technology developers, they also advocate for interdisciplinary partnerships that maximize the potential of EHRs in advancing precision medicine, epidemiology, and digital health solutions. 

Dr. Shen and Dr. Hu of Pennington Biomedical collaborated with Dr. Jiamin Yu and Dr. Jian Zhou of the Department of Endocrinology and Metabolism at the Shanghai Sixth People’s Hospital, which is an affiliate of the Shanghai Jiao Tong University School of Medicine in Shanghai, China.

Arctic cyclones could be missing link in sea ice depletion models




University of Oklahoma




NORMAN, OKLA. – A new study published in Nature Communications Earth and Environment gives possible insight into the underprediction of sea ice depletion and the formation of Arctic cyclones. Led by Steven Cavallo, a professor in the School of Meteorology at the University of Oklahoma, the study could lead to more accurate weather and climate models and better forecasting of Arctic cyclones.

Since 1979, Arctic sea ice extent, a term that describes the area of the Arctic Ocean covered by ice, has been reduced by 40% in the late summer months. Global climate models have consistently underpredicted that reduction. The study examines what Cavallo and his co-authors call “very rapid sea ice loss events,” or VRILEs. The sea ice decline since 1979 is the sum of numerous VRILEs that individually occur in periods of 5 to 18 days.

Cavallo’s publication suggests that Arctic cyclones are at least partially to blame. Arctic cyclones are weather phenomena that are tricky to predict and even trickier to incorporate into models. Though the exact mechanisms of why these cyclones may accelerate the ice loss are not fully understood, Cavallo suggests two theories. The first is the interaction of turbulent seas with ice.

“If the winds get strong and the ice is thin enough, [the cyclone] can create waves that break the larger ice floes. Breaking them up into smaller ice floes accelerates the melting; it can happen at a really fast time scale,” he said.

The second theory is that upwelling, the mixing of warmer water below the sea’s surface with cooler waters at the surface, increases temperatures that help melt the younger, thinner ice from below in a short amount of time.

Observations of these events and their effects are difficult. Ships avoid forecasted storms, and a plane could not fly into an Arctic cyclone close enough to the ocean’s surface to collect data on upwelling or wave–ice interactions.

Cavallo says they’ve discovered that cyclones have to be in the right place to make such a drastic difference to the sea ice extent, needing to occur over an area of thin ice that is usually no more than a year old.

The research also suggests a connection between Arctic cyclones and tropopause polar vortices, or circulation in the upper troposphere over the polar regions.

Cavallo said tropopause polar vortices are sometimes present for months before an Arctic cyclone forms, while Arctic cyclones are usually only predicted several days in advance. Because the vortices are present so far ahead of a cyclone, they could lead to better forecasts of cyclones. This would benefit residents in areas such as Alaska, northern Canada, and Greenland and aid the shipping industry, which has made increased use of the Arctic as ice continues to recede.

“Now that we think these processes are occurring, the question is how do we get that information into the models so that we can get better predictions,” said Cavallo. “It’s a hard task.”

Cavallo says that the broader scientific community is still unsure when the Arctic will become ice-free, but that looming lack of ice could significantly impact large-scale atmospheric dynamics throughout the Northern Hemisphere.

“We’re still trying to figure out exactly how sea ice changes will affect any of the extreme weather that is happening right now.” 

 

 

Combining millions of years of evolution with tech wizardry: the cyborg cockroach



Instead of using robots, researchers at Osaka University and Diponegoro University, Indonesia aim to harness the advantages of cyborg insects to aid in disaster relief and safety inspections under hostile environments

Osaka, Japan – From disaster zones to extreme environments, there remain areas difficult for even humans to reliably access. This poses a problem for search-and-rescue operations, research, surveillance, and more. Now, however, a research team from Osaka University and Diponegoro University, Indonesia is hard at work on one potential solution: the cyborg insect.

Cyborg insects have a lot of advantages over traditional robots. Power consumption is less of an issue, so it’s easier to miniaturize them, and they are even ‘pre-built’ in a sense. However, research on cyborg insects has been limited to simple environments, like flat surfaces supplemented with external devices to aid navigation. The research team wanted to see if a cyborg insect could navigate a more complex, real-world environment.

“The creation of a functioning robot on a small scale is challenging; we wanted to sidestep this obstacle by keeping things simple,” explains Mochammad Ariyanto, lead author of the study. “By simply attaching electronic devices to insects, we can avoid the finer details of robotics engineering and focus on achieving our goals.”

Sensors that detect motion and obstacles were mounted to the cockroaches and were programmed to work alongside their innate abilities, such as climbing or wall-following. The small electronic circuits delivered navigation commands to the cockroaches when needed, but otherwise stayed out of the way, letting the cyborg insects avoid obstacles or recover from falls naturally.    

The team tested the cyborg insects on obstacle courses of sandy ground strewn with stones and wood. Even in relatively complex environments that were unknown to the cockroaches, the cyborg insects were able to overcome obstacles and reach their target destination.

“I believe our cyborg insects can achieve objectives with less effort and power than purely mechanical robots,” says Keisuke Morishima, senior author. “Our autonomous biohybrid navigation system overcomes problems that have traditionally challenged robots, such as recovering from falling. This is what is needed for stepping outside the laboratory and into real-life scenarios like wilderness.”

The cyborg insects already have some jobs lined up. They can inspect post-disaster sites that remain too dangerous for humans and can be used to identify rescue workers in hostile conditions. Of course, they can also be used to explore environments too small for humans, such as pipes or collapsed buildings. More ambitious goals aim to harness their ability to work in low-oxygen environments, facilitating their use in deep-sea or space exploration.

It’s not all daunting work though—the cyborgs could even be allowed entry to some of our most delicate and sensitive cultural heritage sites, a privilege denied to most of humankind. With further research set to improve cyborg speed and navigation even more, rescue teams and archaeologists should be prepared to welcome their new six-legged workers.

Pesticides are causing overwhelming negative effects on hundreds of species of microbes, fungi, plants, insects, fish, birds and mammals that they are not intended to harm – and globally their use is a major contributor to the biodiversity crisis.

That is the finding of the first study assessing the impacts of pesticides across all types of species in land and water habitats, carried out by an international research team that included the UK Centre for Ecology & Hydrology (UKCEH) and the University of Sussex.

Multiple negative impacts

The scientists analysed over 1,700 existing lab and field studies of the impacts of 471 different pesticide types – either insecticides, fungicides or herbicides – in agricultural, commercial or domestic use.

Wide-ranging negative effects were seen for over 800 species found on land and in water, including impacts on how fast they grow, their reproductive success, and even behaviour such as their ability to catch prey, find plants to forage upon, move, or attract mates. Pesticides can also affect organisms’ metabolism and damage cells.

These negative effects can result in the premature death of wild organisms and reduce populations.

The international study, led by East China University of Science and Technology, has been published in Nature Communications.

The researchers say that, unlike previous studies which have tended to look at specific groups of species such as bees, fish or plants, or specific habitats, they have considered representatives of the whole spectrum of species found in the natural world. 

Necessary option

“Our study provides an unparalleled insight into the consequences of pesticide use on the natural environment globally,” said co-author Dr Ben Woodcock, an ecologist at UKCEH.

“Pesticides are a necessary evil, without which global food production and farmers’ livelihoods would likely collapse. However, our findings highlight the need for policies and practices to reduce their use. This could include bottom-up initiatives led by farmers such as regenerative agriculture, as well as government policies such as Defra’s Sustainable Farming Incentive, which pays farmers to reduce insecticide use on crops.”

Professor Dave Goulson of the University of Sussex, who was also part of the research, added: “It is often assumed that pesticides are toxic primarily to the target pest and closely related organisms, but this is clearly not true. Concerningly, we found pervasive negative impacts across plants, animals, fungi and microbes, threatening the integrity of ecosystems.”

Alternatives

Overuse of pesticides not only threatens beneficial species they are not intended to target but can also enable pests to develop resistance to the chemicals, rendering them ineffective. Farms in the UK, for example, are currently encouraged to carry out an Integrated Pest Management assessment which emphasises reduced pesticide use and natural pest control. In the European Union, over 10% of land under agricultural production is organic, using no synthetic pesticides.

Alternative options for farmers include planting wildflowers and beetle banks to support species that eat pests, allowing them to reduce spraying when there are high numbers of these natural predators present. Other measures include adjusting the timing of planting to avoid pests and rotating crops to break the species’ life cycles and reduce their numbers.

Gardeners can do their bit to reduce the use of chemicals. Options for natural pest control include introducing nematodes, ladybirds or mites, which can be bought online, and encouraging other natural predators such as frogs, birds and hedgehogs with wildlife-friendly gardening. Physical barriers such as netting can prevent caterpillar and bird damage.

Future developments

New monitoring work by UKCEH, working with Defra, is currently using honeybee colonies to monitor pesticide risks across England to act as an early warning of emerging problems.

Dr Woodcock pointed out there was a lot of scope in the future for developing agricultural methods to be more responsive to our natural pest controllers, such as AI monitoring of both pests and predators using high-tech cameras.
