Having sex can be fun; and talking about sex can be fun. Talking about sexually transmitted infections with a sexual interest, however, is a totally different matter, according to new research from Indiana University's Center for Sexual Health Promotion.

The study, discussed during the American Public Health Association's annual meeting, found a disconnect between the public health messages that promote STI testing as a way to prevent STIs such as HIV and chlamydia and the conversations - or lack of them - occurring in bedrooms.

"Talking to partners about STIs is an important conversation to have," said Margo Mullinax, lead researcher for "Talk about testing: What sexual partners discuss in relation to STI status and why." "However, findings from this study suggest public health campaigns need to promote specific messages, concrete tips and tools around sexual health conversations stratified by relationship status. Campaigns should also address STI stigma and promote messages of normalcy with regard to talking about STIs."

STIs, if untreated, can lead to a range of health problems including infertility, so a growing public health emphasis has been on preventing STIs through testing. Mullinax said little was known, however, about how STI testing figured into actual conversations between lovers, particularly among the college-age crowd that accounts for a disproportionate number of new STI cases nationwide.

People who speak more than one language and who develop dementia tend to do so up to five years later than those who are monolingual, according to a study.

A team of scientists examined almost 650 dementia patients and assessed when each one had been diagnosed with the condition. The study was carried out by researchers from the University of Edinburgh and Nizam's Institute of Medical Sciences in Hyderabad (India).

They found that people who spoke two or more languages experienced a later onset of Alzheimer's disease, vascular dementia and frontotemporal dementia.

The bilingual advantage extended to illiterate people who had not attended school. This confirms that the observed effect is not caused by differences in formal education.
It is the largest study so far to gauge the impact of bilingualism on the onset of dementia – independent of a person's education, gender, occupation and whether they live in a city or in the country, all of which have been examined as potential factors influencing the onset of dementia.
