Is there meaning and purpose in the universe? This often-debated question is the subject of a June 13 paper by Nobel laureate Brian Josephson and available as a preprint from Research Gate.
Sophisticated physical measurements show how insects and other invertebrates make use of heavy metals to strengthen and sharpen their appendages in a way that is different from the biomineralization process used to form the teeth, bones, and other organs in a wide variety of animals.
The findings of the study, published on September 28 in “Nature Communications”, represent a huge step forward in understanding identical twins.
Nearly 10% of adolescent or teenage girls become pregnant annually, making teen pregnancy a major concern worldwide. A study of the problem in the Nsukka area of Enugu state in Nigeria probed the causes and consequences of teen pregnancies.

Scientists studying probiotics, beneficial bacteria that show promise for their ability to treat inflammatory bowel disease and other intestinal disorders, continue to face a problem: how to keep probiotics from getting obliterated in the gut before they can be helpful.
Researchers at the Universities of Helsinki and Lyon and the Geological Survey of Finland found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional.
