Children who live in homes with adults who use e-cigarettes are exposed to significantly less nicotine from secondhand smoke than children who live in homes with adults who use traditional cigarettes, a new study has found. But e-cigarettes expose children to nicotine and may pose other risks. To fully protect children from nicotine, people should never smoke or vape around them, the researchers said. The perception that e-cigarettes are safer than traditional cigarettes and that they are used more than regular cigarettes in homes is one reason they conducted the study, the researchers said. The study was published Thursday in…

Example results (red, blue, brown, orange) for Models A, B, C, D. The solid and dashed lines show the results when assuming a scalar initial energy of 10% and 1% of the total energy density of the Universe, respectively. Note that Model C has a multi-peaked oscillation signature. Constraints and sensitivities of various GW experiments are also shown. Credits: Physics Review Letter (2024).

A new study has been published. Developmental Cognitive Neuroscience To determine how early life adversity impacts children’s brain development, the researchers found that greater perinatal adversity was associated not only with smaller hippocampal volume in childhood, but also with faster growth of the right hippocampus throughout childhood. Interestingly, this accelerated growth was associated with an increased risk of depressive symptoms later in childhood.Previous research has shown that children exposed to adversity often experience a range of developmental changes. However, few studies have examined brain development across multiple time points to effectively model the pace of development. Researchers sought to gain…

And, in an immeasurable sense, his greatest “hit” may be the theme song he wrote for the Augusta Masters golf tournament,…
