Thousands more children of consanguineous marriages survive, but with appalling physical or mental problems. These include blindness, deafness, blood ailments, heart or kidney failure, lung or liver problems and a myriad of often incurable and complex neurological or brain disorders.
An extra year in school can increase your IQ by up to five points – and the effects will be with you for the rest of your life, according to a new study.
Researchers claim the latest findings are the clearest evidence yet that education raises intelligence, calling the change ‘small but noticeable’.
It also disproves the common myth that intelligence is unchangeable after birth.
A professor at the Royal Holloway, University of London enjoyed a good laugh recently after submitting an obviously fake study to a prominent academic journal, which accepted and published it – no questions asked.
Gary Lewis claimed to have conducted extensive research into the bathroom habits of conservatives and liberals, concluding that those on the left tend to wipe with their right hands, and those on the right with their left hands.
The advice is ever-changing:
Feeding babies solid food from the age of just three months old could help them sleep better and improve their long-term health, a major study has found.
The Government currently advises mothers to feed babies exclusively with breastmilk until they are at least six months, and only then gradually introduce solids.
But the new study suggests that advice is flawed – and suggests babies do better if solid food is given earlier, alongside breastmilk.
The Environmental Protection Agency is sitting on a report that most Americans are inhaling enough formaldehyde vapor to risk developing leukemia or other diseases, according to a report.
A draft of the health assessment of the chemical used in everything from wood furniture to cleaning supplies and make-up was finished before Donald Trump became president, and the EPA has of yet to release their findings.
Some journals now insist that authors pre-register their research protocol and supply their raw data, which makes it harder for researchers to manipulate findings in order to reach a certain conclusion. It also allows other to verify or replicate their studies.
Because when studies are replicated, they rarely come up with the same results.
Birth rates in the United States have recently fallen. Birth rates per 1000 females aged 25–29 fell from 118 in 2007 to 105 in 2015. One factor may involve the vaccination against the human papillomavirus (HPV). Shortly after the vaccine was licensed, several reports of recipients experiencing primary ovarian failure emerged. This study analyzed information gathered in National Health and Nutrition Examination Survey, which represented 8 million 25-to-29-year-old women residing in the United States between 2007 and 2014. Approximately 60% of women who did not receive the HPV vaccine had been pregnant at least once, whereas only 35% of women who were exposed to the vaccine had conceived. For married women, 75% who did not receive the shot were found to conceive, while only 50% who received the vaccine had ever been pregnant. Using logistic regression to analyze the data, the probability of having been pregnant was estimated for females who received an HPV vaccine compared with females who did not receive the shot. Results suggest that females who received the HPV shot were less likely to have ever been pregnant than women in the same age group who did not receive the shot. If 100% of females in this study had received the HPV vaccine, data suggest the number of women having ever conceived would have fallen by 2 million. Further study into the influence of HPV vaccine on fertility is thus warranted.
