Published Link between high levels of niacin -- a common B vitamin -- and heart disease, study suggests (via sciencedaily.com) Original source
Researchers have identified a new pathway that contributes to cardiovascular disease associated with high levels of niacin, a common B vitamin previously recommended to lower cholesterol. The team discovered a link between 4PY, a breakdown product from excess niacin, and heart disease. Higher circulating levels of 4PY were strongly associated with development of heart attack, stroke and other adverse cardiac events in large-scale clinical studies. The researchers also showed in preclinical studies that 4PY directly triggers vascular inflammation which damages blood vessels and can lead to atherosclerosis over time.
Published Great apes playfully tease each other (via sciencedaily.com) Original source
Babies playfully tease others as young as eight months of age. Since language is not required for this behavior, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behavior in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humor evolved in the human lineage at least 13 million years ago.
Published Smart earrings can monitor a person's temperature (via sciencedaily.com) Original source
Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.
Published How teachers make ethical judgments when using AI in the classroom (via sciencedaily.com) Original source

Published Archaeological evidence of seasonal vitamin D deficiency discovered (via sciencedaily.com) Original source
Rickets ran rife in children following the Industrial Revolution, but new research has found factory work and polluted cities aren't entirely to blame for the period's vitamin D deficiencies.
Published Knowing what dogs like to watch could help veterinarians assess their vision (via sciencedaily.com) Original source
A veterinary ophthalmologist wanted to determine factors, including age and vision, that influence a dog's interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision -- something that has been sorely lacking in veterinary medicine. The study found that dogs are most engaged when watching videos that feature other animals.
