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 Alzheimer’s(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.

“It’s 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.”

Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.

“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.

“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”

To get cash out in the 21st century, you won’t need a bank card, a PIN(个人识别编号) or even have to move a finger. You will simply have to look the cash machine straight in the eye, declares National Cash Registers, a multinational company that makes automated teller machines, or ATMs. NCR has shown its first example machine that is believed to be the future of banking. Instead of asking you for your PIN on a screen, the Super Teller-Stella for short, asks you orally through a loudspeaker to look straight ahead while an infrared camera turns to your head, then your eye, and finally takes an infrared photograph of your iris(虹膜). For identification(识别) purposes, an iris picture is better than a fingerprint, with around 256 noticeable characteristics compared with 40 for fingerprints. This means that the chances of someone else being recognized in your place is about 1 in 1020. Once you’ve been identified, Stella greets you by name and says: “Would you like cash or a statement?” An infrared port allows the machine to send a bank statement straight to your pocket computer.
