Are ‘Hookups’ replacing romantic relationships
The casual, no-strings-attached sexual encounters may be replacing traditional romantic relationships among college-goers, a new study suggests.

A good thing, however, is that the students are not actually hooking up as frequently as one might think. According to the study, romantic sex with a boyfriend or relationship partner was found to be twice as common as hookup sex in this particular group of students. For most women, hooking up is experimental.

Eat with your kids to boost their fruit, veggies' intake
Eating meals together as a family, even once or twice a week, increases children’s daily fruit and vegetable intake, according to the researchers at the University of Leeds.

Children, who always ate a family meal together at a table consumed 125g (1.5 portions) more fruit and vegetables on average than children who never ate with their families.

Even those who reported eating together only once or twice a week consumed 95g (1.2 portions) more than those who never ate together.

Even if it’s just one family meal a week, when children eat together with parents or older siblings they learn about eating.

Watching the way their parents or siblings eat and the different types of food they eat is pivotal in creating their own food habits and preferences.

Aerobics best for weight loss
Aerobic exercise that includes walking, running, and swimming are an effective way to lose weight, says a new study.

The exercise is not only beneficial for weight loss, but for fat loss as well. Researchers from the Duke University Medical Centre, US, that conducted the survey on 234 obese adults, found aerobic exercises helped in increasing a person’s overall metabolic rate that resulted in significant weight and fat loss.

The group performing resistance exercises in the survey, however, gained weight due to an increase in lean body mass.

More time on violent video games, more aggression
A new study provides the first experimental evidence that the negative effects of playing violent video games can accumulate over time.

Researchers found that people who played a violent video game for three consecutive days showed increases in aggressive behaviour each day they played. Even a single session of playing a violent video game tends to increase short-term aggression.

Researchers compared playing video games to smoking cigarettes. A single cigarette won’t cause lung cancer, but smoking over weeks or months or years greatly increases the risk.

In the same way, repeated exposure to violent video games may have a cumulative effect on aggression.

Want Your Baby to Learn? Sitting Up Helps
From the Mozart effect to educational videos, many parents want to aid their infants in learning; and a recent research has shown something as simple as the body position of babies while they learn plays a critical role in their cognitive development.

For babies, sitting up, either by themselves or with assistance plays a significant role in how infants learn.

The study’s results show that babies’ ability to sit up unsupported has a profound effect on their ability to learn about objects.

The research also shows that when babies who cannot sit up alone are given posture support from infant seats that help them sit up, they learn as well as babies who can already sit alone.
