Women in cities are less likely to have babies

Women are less likely to procreate in urban areas that have more women than men in the population. Although the majority of modern cities have that statistic and thus suffer from lower fertility rates, the effects of female-biased sex ratios – having more women than men in a population – is less studied than male-biased ratios. A new study in Behavioral Ecology, published by Oxford University Press analysed how female-biased sex ratios are linked to marriages, reproductive histories, dispersal, and the effects of urbanisation on society. The research team from the University of Turku, University of Helsinki, and Pennsylvania State University used a massive internal migration event that occurred in Finland during WWII, when 10 per cent of Finnish territory was ceded to the Soviet Union and over 400,000 citizens were evacuated. The Finnish government implemented a settlement act to …

The THC in ganja can linger in breast milk for up to 6 weeks


Researchers at Children’s Hospital Colorado have found that tetrahydrocannabinol (THC), the psychoactive component of marijuana, stays in breast milk for up to six weeks, further supporting the recommendations to abstain from marijuana use during pregnancy and while a mother is breastfeeding. The findings were published in the journal JAMA Pediatrics. “With the increasing utilization of marijuana in society as a whole, we are seeing more mothers who use marijuana during pregnancy,” said Erica Wymore, MD, MPH, primary investigator, a neonatologist at Children’s Colorado and assistant professor of paediatrics at the University of Colorado School of Medicine on the Anschutz Medical Campus. “However, given the lack of scientific data regarding how long THC persists in breast milk, it was challenging to provide mothers with a definitive answer regarding the safety of using marijuana while breastfeeding and simply ‘pumping and dumping’ until …

youth on laptop

While it is always advisable to lessen the screen time for kids, however, the findings of a novel study say otherwise. The novel study advocates that boys who regularly play video games at age of 11 are less likely to develop depressive symptoms three years later. The study led by a UCL researcher was published in ‘Psychological Medicine’. It also found that girls who spend more time on social media appear to develop more depressive symptoms. Taken together, the findings demonstrate how different types of screen time can positively or negatively influence young people’s mental health, and may also impact boys and girls differently. Lead author, Ph.D. student Aaron Kandola (UCL Psychiatry) said: “Screens allow us to engage in a wide range of activities. Guidelines and recommendations about screen time should be based on our understanding of how these different …
