The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where thick and thin protein-filaments interact within the sarcomere, the fundamental building block of both skeletal and heart muscle cells. Any alterations in thick filament proteins can have severe consequences for our health, leading to conditions such... Read more ›

A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry. Read more ›

Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated. A team has now published a major cross-sectional study on the subject. It shows that frequent use of mobile phones is associated with a lower sperm concentration and... Read more ›

Researchers estimated that before humans started pumping mercury into the atmosphere, it contained on average about 580 megagrams of mercury. However, in 2015, independent research that looked at all available atmospheric measurements estimated the atmospheric mercury reservoir was about 4,000 Mg -- nearly 7 times larger than the natural condition estimated in this study.  Read more ›

A new study has shown that women who are taking the oral contraceptive pill are less likely to report depression. The research, which analysed data from 6,239 women in the United States aged 18-55 years old, found that the prevalence of major depression amongst users of the oral contraceptive pill (OCP) was significantly lower, at 4.6%, compared to former OCP users (11.4%).

Researchers found that employees who prioritize career advancement are strongly affected by abusive leadership while employees who prioritized job security remained just as likely to take charge after experiencing abusive supervision. Employees who prioritize advancement tend to hunker down and reduce taking-charge behavior after experiencing abusive supervision. Read more ›
