The results, published today (Sept. 13) in the journal Proceedings of the Royal Society B, revealed that parents do influence their kids' reproductive decisions, albeit mildly. People who reported a close emotional relationship with parents or reported seeing their own parents frequently were more likely to have children during the following five years than those with more distant attachments. The effect was modest, Waynforth said, but surprisingly stronger than the effect of having parents who provided real help in the form of child care or money. That sort of help did not increase people's likelihood of having kids, he said. … [Read more...] about Close Ties to Children May Ensure Grandkids Later

The researchers found that when they mutated the protein complex that adds a methyl group to a specific histone protein, the nematodes lived up to 30 percent longer than the non-mutants. When the mutant nematodes reproduced with normal nematodes, their offspring (even those without the mutation) lived up to 30 percent longer. The methyl addition that caused the extended lifespan seemed to be passed down, even if the actual mutation wasn't. … [Read more...] about Can You Inherit a Long Life?

Casadevall lays out the dilemma: "BSL-4 containment would theoretically protect society by increasing both biosafety and biosecurity. However, at the same time, this very high level of containment would make society potentially more vulnerable, since critical experimental work will not get done simply because BSL-4 facilities are few in number and already engaged in research with numerous other pathogens." … [Read more...] about Mutant H5N1 Virus Stirs Biosafety Debate
The delay is needed to explain the importance of the research and address anxieties the research has raised, Fukuda said. The delay would also allow officials time to re-assess the biosafety and biosecurity conditions necessary for this kind of work. He pointed out, there was no hint of problems at the two facilities in question. … [Read more...] about Mutant Bird Flu Studies Should Be Revealed in Full, Experts Say
