Sex selection for social reasons: religious and moral perspectives

According to a survey, allowing sex selection in Germany and the UK would be unlikely to skew biological sex balance. However, experts argue that selecting the sex of offspring raises ethical concerns about parental desires vs. unconditional acceptance of children. Most respondents have no intention of using sex selection techniques, r...

Could diabetes treatments fight cancer?

Researchers identified a link between LKB1, an enzyme that reduces blood glucose levels, and AMPK, which inhibits cell growth. This connection could lead to more effective anti-diabetes drugs, such as metformin, also being used to treat cancer. The study found that LKB1 plays a crucial role in preventing tumor growth by activating AMPK.

Resistance exercise resets the body clock

Researchers found that resistance exercise can alter the expression of clock genes in human skeletal muscle, causing a phase shift similar to winding on (resetting) the muscle clock. This suggests that peripheral clocks can regulate themselves independently of the central clock.

Hormonal changes in satisfied and dissatisfied shift workers across a shift cycle

Researchers found that dissatisfied shift workers experienced lower morning testosterone levels, while satisfied workers had no significant differences in cortisol or prolactin. The study suggests that low testosterone levels may contribute to shift intolerance due to disturbed sleep and increased need for recovery.
