Men's and women's brains wired differently
Why are men and women so different? It looks as if one big reason is their brains. A new study published in Proceedings of the National Academy of Sciences says that the different genders are literally wired differently within the brain. Which may explain why each gender is better at different tasks.
Researchers at the University of Pennsylvania scanned the brains of 1,000 males and females of varying ages. The scans showed remarkable differences in the brain makeup. Male brains are wired with most connections between front and back with limited crossing between left and right brain hemispheres. Female brains, meanwhile, are wired between left and right, crisscrossing both hemispheres.
The wiring explains why men are usually better at learning and completing a sole task and women tend to be better at multitasking. The research participants then performed a series of tasks, which supported this hypothesis. Women scored higher on paying attention, social awareness, and word and face memory. Men scored higher in spatial processing and sensory-motor speed.
This study not only addresses the differences in gender thought processes, but also may also provide more insight into neurological disorders.

Study says you can't be obese and healthy
A new study published in the Annals of Internal Medicine contends that it’s not really possible to be both obese and healthy. The researchers concluded that obesity alone increases the risk of death.
Scientists at Sinai Hospital in Toronto analyzed data from eight other studies involving more than 61,000 people, who were mostly middle age. The researchers looked only at studies that followed participants for a minimum of 10 years.
Of this sector, people who were obese with no metabolic complications—heart disease, high blood pressure, high cholesterol—still had a 24 percent higher risk of experiencing heart problems at some point, compared to people at a normal weight with no metabolic complications. The researchers said that this demonstrates that it’s not possible to be obese and healthy.
However, the study has already drawn criticism from the medical community. Some say metabolic risk factors are much more dangerous for heart health than weight. Another study earlier this year concluded that overweight people tend to live longer than people at a normal weight. The study also couldn’t factor in the physical activity of participants, which could affect the risk of death.
