5 studies you may have missed

Here are five medical studies published this week that may give you new insights into your health, mind and body. Remember, correlation is not causation, so if a study finds a connection between two things, it doesn't mean that one causes the other.

Babies could learn melodies in the womb
Journal: PLOS ONE

Turns out your baby could be "Born this Way" - or at least born a Lady Gaga fan.

In this study, moms who played "Twinkle Twinkle Little Star" to their fetuses had babies who showed more brain activity in response to the song after birth than those whose moms didn't play the nursery rhyme.

"These results show that babies are capable of learning at a very young age, and that the effects of the learning remain apparent in the brain for a long time," cognitive brain researcher Eino Partanen told The Guardian.

That health app may not help
Released by IMS Institute for Healthcare Informatics

The IMS Institute for Healthcare Informatics analyzed data from 40,000+ health care apps to determine if the industry is using mobile technology to the best of its ability.

Unfortunately, what they found wasn't very favorable. More than 50% of the apps had been downloaded less than 500 times, and the majority came without any kind of medical guidance.

"Healthcare apps available today have both limited and simple functionality - the majority do little more than provide information," the authors concluded.

We're more moral in the morning
Journal: Psychological Science

Hoping to have an open and honest conversation with your partner? Better schedule it for the early a.m.

Ethics researchers Maryam Kouchaki and Isaac Smith noticed that experiments they did in the morning seemed to produce fewer instances of unethical behavior. So they decided to test that variable.

The researchers asked college students to choose which side of a computer screen had more dots - left or right. Instead of being paid for the correct answer, the students knew they would be paid more if they chose the right side of the screen. Participants tested in the morning were less likely to select the wrong side for more money than those tested in the afternoon.

The researchers concluded that we're more likely to cheat or lie in the afternoon because our self-control is diminished over the course of the day.

Or maybe college students are just broke.

Excessive noise hurts more than our hearing
Journal: The Lancet

We know that listening to loud music can damage our ears, potentially causing hearing loss long-term. But researchers in Europe wanted to know if excessive noise can also cause other health problems.

They concluded that "noise exposure leads to annoyance, disturbs sleep and causes daytime sleepiness, affects patient outcomes and staff performance in hospitals, increases the occurrence of hypertension and cardiovascular disease, and impairs cognitive performance in schoolchildren."

11 new Alzheimer's genes identified
Journal: Nature Genetics

Researchers with the International Genomics of Alzheimer’s Project announced this week they have doubled the number of known genes linked to Alzheimer's disease. They identified the 11 new genes by collecting genetic information from 25,500 Alzheimer’s patients and 49,038 people without the disease from 15 countries.

"This exciting discovery of genes linked with Alzheimer's disease opens up new avenues to explore in the search for treatments for the condition," Dr. James Pickett, head of research for the Alzheimer's Society, said in a statement. "We now need continued global investment into dementia research to understand exactly how these genes affect the disease process."
