Birds along elevation gradients serve as models for examining physiological adaptations, such as elevated hemoglobin concentrations at high altitudes due to lower oxygen availability. This study aimed to examine how various ecological traits influence the haemoglobin concentration responses of multiple bird taxa to an elevation gradient.

I was doing some research on mitochondrial DNA and and kept getting conflicting information on the entire orientation and direction of its circular structure. Some are clockwise oriented, some counter clockwise, some unify the L and H strand, some split them, some reverse the L and H strands.

It is proposed that happiness be classified as a psychiatric disorder and be included in future editions of the major diagnostic manuals under the new name: major affective disorder, pleasant type. In a review of the relevant literature it is shown that happiness is statistically abnormal, consists of a discrete cluster of symptoms, is associated with a range of cognitive abnormalities, and probably reflects the abnormal functioning of the central nervous system. One possible objection to this proposal remains–that happiness is not negatively valued. However, this objection is dismissed as scientifically irrelevant.

In earlier holocene neolithic and bronze age societies, sharp population increases and downturns closely tracked periods of climate instabilty, pointing at agricultural strategies failing as weather gets unpredictable.

in papers such as these the conclusion is that multi-tasking lowers mental health (lowers working memory & ability to filter out impressions while increasing distractability & stress.)

I was wondering why people warm up in sweatshirts. I guess it helps

Is the post-COVID-19 syndrome a severe impairment of acetylcholine-orchestrated neuromodulation that responds to nicotine administration?

Mycelium skins function as sustainable substrates for high-performance electronic devices and batteries for a green future.

With a Batman (person in costume) present in the subway, seat offered to a pregnant person increased from 37 % to 67 %.

A good, recent overview of methods for recycling various commodity plastics, especially alternatives to mechanical recycling (e.g. chemical depolymerization, gasification). The effects on worker health and the environment in general are also considered.

TLDR: Middle-aged rats who were given varying doses of β-hydroxy β-methylbutyrate (HMB), a metabolite of the essential amino acid leucine showed improvements in memory.

Se suposa que mascles i femelles tenim grans diferències genètiques, i el determinisme biològista pretén que el patriarcat està codificat als nostres gens.

This study explores map applications by evaluating them using WCAG 2.1 Standards. It found that XR Navigation’s Audiom was the most accessible mapping platform. Most mapping platforms, like Google Maps, Bing, and TomTom, have some significant accessibility barriers. Common mapping issues included providing text equivalent alternatives, keyboard accessibility, and color contrast issues. Check out the full article for more information. #accessibility

Dairy milk products are dominant in the market; however, plant-based milks are gaining prominence among USA consumers. Many questions remain about how plant-based milk products compare to dairy milk from a nutrition, public health, and planetary health perspective. Here, we compare the retail sales, nutrient profiles, and known health and environmental impacts of the production and consumption of dairy and plant-based milks and identify knowledge gaps for future studies. For our plant-based milk comparisons, we reviewed almond, soy, oat, coconut, rice, pea, cashew, and other plant-based milks as data were available.

Summary: back in 2008, researchers found a big difference between the incidence and mortality of prostate cancer in Asian and “western” countries (even if situated in Asia). Incidence of the disease in “western” countries was several times higher. Additional data was pulled in to determine if the cause was genetic. People of Asian descent born in “western” countries had a comparably high risk, but people who had immigrated to “western” countries retained a lower risk. Thus, evidence pointed at society. The obvious candidate explanation was eating food that contains phytoestrogens from soy beans.

Sorry but I had to share this, it’s gold, and such an on point critique. And very relevant for anyone informing clinical decisions with RCTs.

This paper covers a potential causal link between cellular senescence and various aging phenotypes. Removing senescent cells exhibiting the kinase inhibitor and senescence biomarker p16 delayed the onset of age-related phenotypes in mouse skeletal muscle, adipose, and eye tissues.
