We Share Stories Online That Make Us Look Good

The magic formula for creating something that will go viral is a mystery for bloggers, journalists and social media personalities. More often than not, the stories we all decide to share seem utterly random. But scientists have started doing more research into why we share certain stories online while others don't warrant so much as a like -it's because we're mainly interested in ourselves. Researchers from the Annenberg School for Communication at the University of Pennsylvania scanned people's brains using an MRI to try and discover exactly what happens in our minds when we click `share'. The results of the experiment show that the articles we share are most likely to be ones that provide the potential for self-enhancement and social promotion.

How Hand Sanitizers Can Harm Children

Scientists have warned that hand sanitizers might do more harm than good. They have found these alcoholbased, scented products might tempt young kids to swallow the substance -leading to stomach pain, nausea, apnea and even coma.Researchers from US Centers for Disease Control (CDC) and Prevention have identified serious consequences, including apnea, acidosis and coma in young children who swallowed alcohol-based hand sanitizers. The study found majority of intentional exposures to alcohol hand sanitizers occurred in children aged 6-12 years. During 2011-2014, 70,669 hand sanitizer exposures in children aged 12 years were reported, of which 65,293 (92 percent) were alcohol exposures and 5,376 (8 percent) were non-alcohol exposures. These data also indicate that, among older children, exposures occur less frequently during the summer months.

Coloring Hair Can Up Chances of Breast Cancer

Researchers from the University of Helsinki in Finland and Finnish Cancer Registry evaluated the contribution of the use of hormonal contraceptives and hair dyes on breast cancer risk factors. They analyzed self-reported survey data from 8,000 breast cancer patients and 20,000 controls from Finland. The results suggested that use of other hormonal contraceptives was, by contrast, associated with 32 percent higher breast cancer risk among younger women under 50 when compared to women who did not use hormonal contraceptives. The team also investigated the amount of opportunistic mammography, which was found to be very common. More than 60 percent of responders reported having had a mammography before the screening age of 50.
