AI-enhanced infrared thermography for reliable detection of temperature patterns in calves

Sensitive region detection for improved non-invasive cattle monitoring

2025-08-13

(Press-News.org) Traditional veterinary practices utilize rectal measurements to assess body temperature, but this method is stressful and does not capture continuous changes in body temperature. Fortunately, recent advancements have introduced infrared thermography, which can non-invasively measure body temperatures. However, it is still difficult to continuously monitor temperature changes over time with this method. Moreso, parts of the image data are set manually, which can cause data variations due to setting positions. These drawbacks prompt the need for significant improvements in infrared thermography methods.

Assistant Professor Sueun Kim’s team at Osaka Metropolitan University’s Graduate School of Veterinary Science used infrared cameras to obtain temperature data of 11 calves and simultaneously recorded video footage. The team sought to determine whether regions of the eyes and nose had higher temperature outputs, and if they exhibited consistent temperature change.

In the experiment, regions of interest (ROI) (the eyes and nose) were automatically pinpointed from the video data by using artificial intelligence segmentation. Approximately 200 temperature change patterns were found, and data analysis showed consistent similarities between patterns based on the top 10% and top 30% values with high body temperatures in both the eyes and nose.

“This research has made it possible to obtain more consistent patterns of changes in cattle body temperature without contact. This enables various statistical analyses and is hoped to be a useful tool for more accurately assessing the health and stress levels of animals in the future,” stated Dr. Kim.

The study was published in BMC Veterinary Research.

Now you see me, now you don’t: how subtle ‘sponsored content’ on social media tricks us into viewing ads

2025-08-13

How many ads do you see on social media? It might be more than you realize. Scientists studying how ads work on Instagram-style social media have found that people are not as good at spotting them as they think. If people recognized ads, they usually ignored them - but some, designed to blend in with your friends’ posts, flew under the radar. “We wanted to understand how ads are really experienced in daily scrolling — beyond what people say they notice, to what they actually process,” said Maike Hübner, PhD candidate at the University ...

New method loads mRNA into exosomes in 10 minutes—just mix and go

2025-08-13

Exosomes, naturally derived vesicles responsible for intercellular communication, are emerging as next-generation drug delivery systems capable of transporting therapeutics to specific cells. However, their tightly packed, cholesterol-rich membranes make it extremely difficult to encapsulate large molecules such as mRNA or proteins. Conventional approaches have relied on techniques like electroporation or chemical treatment, which often damage both the drugs and exosomes, reduce delivery efficiency, and require complex purification steps—all of which pose significant barriers to commercialization. A joint research team led by Dr. Hojun Kim at the Center ...

Concerns about sexual function persist well beyond midlife

2025-08-13

CLEVELAND, Ohio (August 13, 2025)—Adults aged 65 years and older are becoming the fastest-growing demographic, yet, the sexual health of older women is often understudied and untreated. A new study demonstrates their rate of sexual problems is similar to that of midlife women, although they are less likely to report distress related to their sexual problems. Results of the study are published online today in Menopause, the journal of The Menopause Society. Although sexual activity declines with age, sexual health remains relevant throughout life ...

Can grapevines help slow the plastic waste problem?

2025-08-13

The need for biodegradable packaging material has never been higher. Currently, most packaging is "single use" and is made with plastic materials, derived from nonrenewable sources like crude oil that take hundreds of years to decompose in the environment. On top of this, only 9% of plastic is recycled. This has resulted in the formation of floating piles of plastic garbage in the ocean, called the "Great Pacific Garbage Patch." But maybe even more concerning is the discovery of micro- and nano-plastics in the environment. Research has found that plastic breaks down into tiny ...

People disregard advice when making tough decisions

2025-08-13

An international study surveying people in a dozen countries found that when it comes to making complex decisions, people all over the world tend to reflect on their own, rather than seek advice. Researchers from the University of Waterloo led the new study that surveyed more than 3,500 people from megacities to small Indigenous communities in the Amazon rainforest to learn how they make decisions. This work is the broadest test of decision-style preferences across cultures to date. The researchers ...

Study reveals how small changes in walking technique may help treat knee osteoarthritis

2025-08-12

Gait analysis and pain measures show that subtly adjusting the angle of the foot during walking may reduce knee pain caused by osteoarthritis. This approach may also slow progression of the condition, an uncurable disease in which the cartilage cushion inside a joint breaks down. Led by a team of researchers at NYU Langone Health, the University of Utah, and Stanford University, a new study explored whether changing the way patients position their feet when walking could lessen extra loading — stress on the joint during motion — and help treat the disease. For ...

Reciprocal links likely between certain groups of gut bacteria and insomnia risk

2025-08-12

There seem to be reciprocal links between certain groups of gut bacteria and the risk of insomnia, suggests a Mendelian randomisation study, published in the open access journal General Psychiatry. Certain types of bacteria seem to boost or lower the risk of the sleep disorder while insomnia itself seems to alter the abundance of certain types of bacteria, the findings indicate. Several studies have explored the effects of the gut microbiome on various sleep characteristics, but it’s not yet clear how different groups ...

Taste and price, not calories, key drivers for online takeaway orders, survey suggests

2025-08-12

Taste and price, rather than calorie content, seem to be the key considerations for those ordering takeaways online, despite calorie labelling legislation designed to help consumers make healthier food choices, suggests an analysis of survey responses, published in the open access journal BMJ Nutrition Prevention & Health. These orders tend to be favoured by younger people and those living with obesity, the responses indicate. And the limited impact of calorie labelling, despite relatively high awareness of the regulations, suggests that additional strategies are needed, say the researchers. Takeaways are ...

Patients still view doctor’s white coat as symbol of professionalism and trust

2025-08-12

Patients are still more likely to trust doctors and consider them more professional when they wear white coats, although women doctors in this attire are often misidentified as nurses or medical assistants, finds a review of the available research on the topic, published in the open access journal BMJ Open. But patient preferences for doctors’ attire seem to be strongly influenced by clinical context and medical specialty, with a growing acceptance of scrubs, especially in emergency or high-risk settings, the findings indicate. In the 19th century, doctors primarily wore black, because medical encounters were viewed as serious and formal occasions. ...

The Lancet Gastroenterology & Hepatology: Routine AI assistance may lead to loss of skills in health professionals who perform colonoscopies, study suggests

2025-08-12

The Lancet Gastroenterology & Hepatology: Routine AI assistance may lead to loss of skills in health professionals who perform colonoscopies, study suggests An observational study of over 1,400 colonoscopies found the rate at which experienced health professionals detect precancerous growths in the colon in non-AI assisted colonoscopies decreased by 20% (from 28.4% to 22.4%) several months after the routine introduction of AI. Several studies have suggested that AI assistance may help doctors identify some cancers, but this is the first study to suggest the implementation of AI could lead to a reduction in the ability of ...
