Louis J. Sheehan, Esquire . At dozens of beaches around the world, huge female sea turtles come
back each year at about the same time. They slowly haul themselves out
of the water near the places they themselves hatched, dig shallow holes
in the sand, and lay clutches of eggs. The predictability of the
turtles' return has made capture of the endangered reptiles and their
eggs a reliable bonanza for poachers. http://louis6j6sheehan.blogspot.com

Louis J. Sheehan, Esquire . It took less than a century after John Deere unveiled his
steel-bladed plow in 1837 for the North American prairie to all but
disappear. For 20 million years, a nearly 1,000-mile-wide swath of
unbroken grassland belted the continent's midsection from northern
Canada to Mexico. Now, only about 5 percent is left, mainly as mixed
and shortgrass prairie in the Plains states. To the east, less than 1
percent of the original lush tallgrass remains, most of it |
Louis J. Sheehan, Esquire . At some time or another, most children in the United States
experience corporal punishment, such as spanking, without suffering
harmful effects on their behavior or mental health. However, studies
conducted over the past 62 years indicate that the more often and the
more harshly parents resort to physical reprimands, the more likely
their kids are to become aggressive, delinquent, and depressed,
contends psychologist Elizabeth T. Gershoff of Columbia |

necessarily work harder, but clusters of them form cooperative units, a
new study suggests. http://louis-j-sheehan-esquire.blog.friendster.com/
This unifying brain process, in which nerve
cells briefly align the peaks and valleys of their electrical
outbursts, may underlie an animal's shifting of attention to a
particular sight, sound, or other sensation, according to a team of
neuroscientists led |
Louis J. Sheehan, Esquire. Eight years ago, when Erik Ramsey was 16, a car accident triggered a
brain stem stroke that left him paralyzed. Though fully conscious,
Ramsey was completely paralyzed, essentially “locked in,” unable to
move or talk. He could communicate only by moving his eyes up or down,
thereby answering questions with a yes or a no. http://louis9j9sheehan.blog.com
Ramsey’s doctors recommended sending him to a nursing facility.
Instead his parents brought him |
Louis J. Sheehan, Esquire. It’s nuclear physics 101: Radioactivity proceeds at its own pace.
Each type of radioactive isotope, be it plutonium-238 or carbon-14,
changes into another isotope or element at a specific, universal,
immutable rate. This much has been known for more than a century, since
Ernest Rutherford defined the notion of half-life—the time it takes for
half of the atoms in a radioactive sample to transmute into something
else. So when researchers suggested in August |
Daily doses of vitamins B-6, B-12 and folate (B-9) don’t raise or
lower a woman’s risk of getting cancer, researchers report in the Nov.
5 Journal of the American Medical Association.
The large trial may put to rest suggestions raised by smaller
studies that these vitamins might deter certain cancers or, as one
study suggested, increase them. http://louis9j9sheehan.blog.com
All three vitamins play key roles in DNA synthesis. Ten years ago,
the United States began to fortify many foods |
