Walls of shops, remains of streets and gold artifacts have been found and recovered.
Some experts believe that the port cities were destroyed by a series of massive earthquakes, much like the quakes scientists believe felled Troy(特洛伊城), Jericho and other ancient cities. The uniform direction of the collapsed columns and walls suggest an earthquake, Goddio said, but no fault lines have been found nearby.
Other researchers believe a massive wave, caused by either an offshore earthquake or a distant underwater landslide, could explain the catastrophe. Still others think rising seas and a shift in the Nile River outlet doomed the cities.
The argument, as you can see, continues, Goddio said.

Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. reseachers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimers(早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
Our research shows that the hormones of pregnancy(怀孕) are protecting the brain, including estrogen(雌激素), which we know has many neuroprotective (保护神经的) effects, Kinsley said.
Its rat data but humans are mammals just like these animals are mammals, he added in a telephone interview. They go through pregnancy and hormonal changes.(责任编辑：www.360gaokao.com)
