Large language models can't effectively recognize users' motivation, but can support behavior change for those ready to act      (via sciencedaily.com)     Original source 

Large language model-based chatbots can't effectively recognize users' motivation when they are hesitant about making healthy behavior changes, but they can support those who are committed to take action, say researchers.

Alzheimer's disease without symptoms: How is that possible?      (via sciencedaily.com)     Original source 

Everyone experiences aging in their own way, and factors such as genetics, lifestyle and environment play a role in this process. Some individuals reach the age of 90 or even 100 in good health, without medications or brain disease. But how do these individuals maintain their health as they age?

Study links sleep apnea severity during REM stage to verbal memory decline      (via sciencedaily.com)     Original source 

A research team has revealed the link between the frequency of sleep apnea events during the rapid-eye-movement stage and the severity of verbal memory impairment in older adults at risk for Alzheimer's disease. Verbal memory refers to the cognitive ability to retain and recall information presented through spoken words or written text and is particularly vulnerable to Alzheimer's.

People without an inner voice have poorer verbal memory      (via sciencedaily.com)     Original source 

The vast majority of people have an ongoing conversation with themselves, an inner voice, that plays an important role in their daily lives. But between 5-10 per cent of the population do not have the same experience of an inner voice, and they find it more difficult to perform certain verbal memory tasks, new research shows.

Some brain cells age faster and are more prevalent in Alzheimer's      (via sciencedaily.com)     Original source 

Engineers have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer's disease. Additionally, researchers observed male-female-specific differences in the aging process of certain brain cells, with the female cortex exhibiting a higher ratio of 'old' oligodendrocytes to 'old' neurons compared to the male cortex. The discoveries were made possible by a new technique called MUSIC (multinucleic acid interaction mapping in single cells), which allows researchers to peek inside individual brain cells and map out interactions between chromatin--which is the tightly coiled form of DNA -- and RNA.

Distinct population of 'troublemaker' platelet cells appear with aging, lead to blood clotting, disease      (via sciencedaily.com)     Original source 

Researchers have discovered a distinct, secondary population of platelets that appears with aging and have hyperreactive behavior and unique molecular properties, which could make them easier to target with medication.

Metabolism of autism reveals developmental origins      (via sciencedaily.com)     Original source 

Researchers have shed new light on the changes in metabolism that occur between birth and the presentation of autism spectrum disorder (ASD) later in childhood. The researchers discovered that a small number of biochemical pathways are responsible for the majority of these changes, which could help inform new early detection and prevention strategies for autism.

How biological aging clocks tick      (via sciencedaily.com)     Original source 

Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a program. Scientists have now discovered that aging clocks actually measure the increase in stochastic changes in cells.

Who should receive preventive treatment for TB? Individuals of all ages with positive skin or blood test      (via sciencedaily.com)     Original source 

Researcher found that exposed individuals with confirmed TB infection -- i.e. a positive skin or blood test -- should receive priority treatment in settings with a low prevalence of the disease, regardless of their age. However, in high-burden settings, all exposed individuals should be considered for preventative treatment, even without a confirmed infection. This strategy can help end the tuberculosis epidemic and support global public health efforts to reduce TB mortality by 95 percent by 2035 (from 2015 estimates).

More than 321,000 U.S. children lost a parent to drug overdose from 2011 to 2021      (via sciencedaily.com)     Original source 

An estimated 321,566 children in the United States lost a parent to drug overdose from 2011 to 2021, according to a new study. The rate of children who experienced this loss more than doubled during this period, from approximately 27 to 63 children per 100,000. The highest number of affected children were those with non-Hispanic white parents, but communities of color and tribal communities were disproportionately affected.

THC lingers in breastmilk with no clear peak point      (via sciencedaily.com)     Original source 

When breastfeeding mothers in a recent study used cannabis, its psychoactive component THC showed up in the milk they produced. The research also found that, unlike alcohol, when THC was detected in milk there was no consistent time when its concentration peaked and started to decline. Importantly, the researchers discovered that the amount of THC they detected in milk was low -- they estimated that infants received an average of 0.07 mg of THC per day. For comparison, a common low-dose edible contains 2 mg of THC. The research team stressed that it is unknown whether this amount has any impact on the infant.
