Girls’ brains can begin maturing from the age of 10 while some men have to wait until 20 before the same organisational structures take place, Newcastle University scientists have found.
They discovered that as the brain matures it begins to ‘prune’ information that is stored and focus on what is important. For girls this can happen as early as 10 years old, but for boys it can take until between 15 and 20 for the same.
The entire human race outside Africa owes its existence to the survival of a single tribe of around 200 people who crossed the Red Sea 70,000 years ago, scientists have discovered. While there are 14 ancestral populations in Africa itself, just one seems to have survived outside of the continent.
The earliest human remains found outside of Africa were discovered in Palestine and are thought to be around 100,000 years old. They are remains of a group that left Africa through what is now the Sahara desert during a brief period when the climate grew wetter, turning the desert green with vegetation. This excursion, however, failed and the population died out when the climate started to dry out again.
When people hear that I have six kids, the reaction is usually entertaining. Sure, there are some days when I wonder what I’ve gotten myself into, worry about the world they’ll inherit, and/or consider the environmental footprint of a family like mine.
But most of the time I just celebrate how awesome it is to have six kids. Here are a few reasons why: READ MORE…
In 2005, our lab uncovered one of the most pervasive genetic mutations on SLC24A5, the contributor to the light skin color of Europeans. When compared to Africans, Europeans are 10-20 times more susceptible to the deadliest form of skin cancer—melanoma. Despite their similarly light skin color, East Asians have melanoma incidences similar to Africans.
linguistically “whiteness” = “albinism”…
Even the relatively minor innovations to existing technologies for which African-Americans were responsible are important and vital. But the “LIFE WITHOUT BLACK PEOPLE” piece misses its target due to too many inaccuracies and trivialities. There is much to laud in the roll call of African-American inventors, and someone should do them better service than the “Life without Black People” article does.
If a woman is physically active during pregnancy, she may boost the development of her unborn child’s brain, according to a heart-tugging new study of expectant mothers and their newborns. The findings bolster a growing scientific consensus that the benefits of exercise can begin to accumulate even before someone is born.
A recent study has found that mothers who consumed nuts at least five times a month were almost 70 percent less likely to have a baby with a nut allergy than those who ate nuts less than once a month.
THE solution to one of America’s most vexing problems — our soaring rates of obesity and diet-related diseases — may have its roots in early childhood, and even in utero.
Niijima was first noticed on November 20. On the next day, the Japanese coast guard released video of the island forming, showing billowing smoke, steam, ash, and rocks exploding from a crater that had erupted from the sea.
At the time, Japanese scientists were unsure how long the island would last, as the ocean often reclaims such volcanic islets within a short time.
Since then, however, the island has grown significantly, thanks to ongoing eruptions of the underlying volcano.
