Resistance, endurance-training best for heart health
A study of triathletes has revealed that the heart adapts to triathlon training by working more efficiently. Triathlons are multi-sport events consisting of swimming, cycling and running various distances in succession. “To our knowledge, this is the first study using MRI to investigate effects of triathlon training on cardiac adaptations,” said lead researcher Michael M.

Oxytocin Increases Trust, Not Gullibility
SATURDAY, Aug. 28 — While the hormone oxytocin makes people more trusting, it doesn’t make them more gullible, a new study shows. Oxytocin — a naturally occurring hormone that functions as a neurotransmitter in the brain — plays an important role in social behavior. Increased levels of the hormone have been linked with better maternal-infant [...]
SATURDAY, Aug. 28 — While the hormone oxytocin makes people more trusting, it doesn’t make them more gullible, a new study shows.
Oxytocin — a naturally occurring hormone that functions as a neurotransmitter in the brain — plays an important role in social behavior. Increased levels of the hormone have been linked with better maternal-infant bonding and greater overall caring, generosity and trust, but it hasn’t been known whether this heightened trust was selective.
In this Belgian study, participants received either a placebo nasal spray or an oxytocin nasal spray, and were then asked to play a trust game in which they received a certain amount of money they could share with a partner.
Study shows students need help to save money, but don’t always know it
A new study has suggested that students could use help saving more money, but they don’t always know it. Most people intend to save more money, and spend less, than they currently do. If they were offered a simple way to do so, would they take it? New research suggests the answer is no. And [...]
A new study has suggested that students could use help saving more money, but they don’t always know it.
Most people intend to save more money, and spend less, than they currently do. If they were offered a simple way to do so, would they take it? New research suggests the answer is no.
And the reason is that their very good intentions can give rise to a sense of optimism that leads them to undervalue opportunities that could make it easier to actually achieve a long-term savings goal.
“Our results highlight the costs of being too optimistic,” said the study’s senior author, psychology professor Derek Koehler.
Researchers at Waterloo asked students in the university’s co- operative education program to set a savings goal at the beginning of a work term, and then asked them again at the end of the term whether they had met their goal. Co-op stu
Childhood obesity rated biggest health problem for kids
A new study has revealed that the problem of childhood obesity is getting worse in the United States. The University of Michigan C.S.

A new study has revealed that the problem of childhood obesity is getting worse in the United States.
The University of Michigan C.S. Mott Children’s Hospital conducted a National Poll on Children’s Health and it showed that adults in the United States rate childhood obesity the biggest health problem for kids.
In May 2010, as many as 2,064 adults were asked to rate 20 different health concerns for children living in their communities.
The top 10 overall health concerns for U.S. children in 2010 and the percentage of adults who rate each as a “big problem” include:
1. Childhood obesity, 38 percent 2. Drug abuse, 30 percent 3. Smoking, 29 percent 4. Internet safety, 25 percent 5. Stress,

Preschool kids use statistics to understand others
Preschool kids can figure out another person’s preferences by using—believe it or not—statistics. In one experiment, children aged 3 and 4 saw a puppet named “Squirrel” remove five toys of the same type from a container full of toys and happily play with them. Across children, the toys that Squirrel removed were the same (for [...]
Preschool kids can figure out another person’s preferences by using—believe it or not—statistics.
In one experiment, children aged 3 and 4 saw a puppet named “Squirrel” remove five toys of the same type from a container full of toys and happily play with them.
Across children, the toys that Squirrel removed were the same (for example, all five were blue flowers).
However, the contents of the container were varied—for one-third of the children, 100 percent of the toys were the same type (so, in this example, all were blue flowers).
For another third of the children, only 50 percent were that type (that is, half were blue flowers and half were red circles).

Childhood adversity ‘can increase heart disease risk in adulthood’
Scientists have found that early life adversity through poverty, social isolation or abuse in childhood is linked to heightened reactivity, which can lead to heart disease later on. “Many diseases first diagnosed in mid-life can be traced back to childhood,” said Karen A. Matthews, a professor of psychiatry and epidemiology at the University of Pittsburgh. [...]

“Having some bad health habits in your 20s and 30s is part of the reason why people get diseases later on. However, it isn”t the whole reason. The evi
Girls as young as seven hitting puberty in US
A new research has revealed that girls in the U.S. are hitting puberty at earlier ages, which makes them prone to the risk of breast cancer in the later stages of life.

A new research has revealed that girls in the U.S. are hitting puberty at earlier ages, which makes them prone to the risk of breast cancer in the later stages of life.
A new study has shown that American girls are hitting puberty as young as seven-years-old.
Jennifer Ashton said that the trend might be related to obesity and environmental toxins.
At age seven, about 10 percent of white girls and 23 percent of black girls had started developing breasts, compared to five percent of white girls and 15 percent of black girls in 1997, according to a study led by Dr.
