A new study suggests that the number of children a woman has might affect her rate of ageing and her lifespan. Research from the University of Helsinki in Finland found that women who had five children or more, or no children, aged faster than those who had a small number of kids. Researcher Mikaela Hukkanen said: "From an evolutionary biology perspective, organisms have limited resources, such as time and energy. When a large amount of energy is invested in reproduction, it is taken away from bodily maintenance and repair mechanisms, which could reduce lifespan." She added that the finding of shorter lifespans of women who never gave birth was "surprising".
The researchers used historical data in their analysis of parenthood and ageing. They analysed the health data on 14,836 women. Researchers examined DNA data and blood samples, then modelled the effects of reproduction on women’s rates of ageing and longevity. Ms. Hukkanen postulated that having a smaller number of pregnancies could have favourable effects on a mother’s health. One benefit is a possible lower risk of breast and ovarian cancer. However, the "wear and tear" and physical demands of multiple childbirths can negate this lowered risk. Another factor that could increase longevity is the increased social support a mother receives from the state for having children.

The text suggests that the lower risk of breast and ovarian cancer completely offsets the negative physical consequences of multiple childbirths.
Hyundai Motor Group says it will roll out human-like robots in its factories from 2028, as major companies race to use the new technology. The South Korean firm showed off Atlas, a humanoid robot developed by Boston Dynamics, at the Consumer Electronics Show (CES) in Las Vegas on Monday. Hyundai says it "plans to integrate Atlas across its global network", including a plant in the US state of Georgia that was involved in a massive immigration raid in 2025. Other firms that have said they will use humanoid robots in their operations include Amazon, Tesla, and Chinese car making giant BYD.
The Atlas robots will gradually take on more tasks, said Hyundai. The firm owns a majority stake in Boston Dynamics, the technology company famous for Spot, the robot dog. Atlas, which is designed for general industrial use, is being developed to work alongside people and autonomously manage machines. Hyundai said the robots will help ease physical strain on human workers, handle potentially dangerous tasks and pave the way for wider use of the technology. The firm did not say how many robots it would initially deploy or how much the project will cost.
