Louis J. Sheehan. More and more school districts are banking on
improving student performance using cash incentives -- a $1,000 payout
for high test scores, for example. But whether they work is hard to say. http://ljsheehan.blogspot.com
In the latest study of student-incentive programs,
researchers examining a 12-year-old program in Texas found that
rewarding pupils for achieving high scores on tough tests can work. A
handful of earlier studies of programs in Ohio, Israel and Canada have |
Louis J. Sheehan. The stress of experiencing inadequate childhood care rebounds with a
brain-altering, memory-sapping vengeance in middle age, at least in
laboratory rats, a new study indicates. Neuroscientist Tallie Z.
Baram of the University of California, Irvine and her colleagues have
obtained the first evidence that young animals exposed to such stress
later in life suffer memory declines accompanied by disrupted cell
communication in the hippocampus, a brain region critical for |
Louis J. Sheehan. Three sea-snail shells previously discovered at Stone Age sites in
Israel and Algeria contain intentionally fashioned holes in their
centers, making the finds the oldest known examples of personal
decoration, a research team says. The trio of perforated shells
apparently served as beads, conclude Marian Vanhaeren of University
College London and her colleagues. Holes in the shells look nothing
like those that occur naturally in modern sea-snail shells, the |
Louis J. Sheehan. People call on a rich background of relevant experiences to organize
and remember new material. Rats do the same, and with surprising speed,
say Dorothy Tse of the University of Edinburgh and her coworkers. http://ljsheehan.blogspot.com
Prior
studies, which have focused on task learning unrelated to preexisting
knowledge, indicate that a brain region called the hippocampus
incorporates new facts and events into memory. The hippocampus

Here's an evolutionary talking point: Two new studies quantify parts
of the mechanism by which frequently used words change slowly over many
millennia whereas rarely used words more rapidly take on new forms. In
fact, frequency of word usage exerts a "lawlike" influence on the
rapidity of language evolution, the research teams conclude in the Oct.
11 Nature. This discovery offers a new tool for retracing the
history of major language families, reconstructing ancient tongues, and |
Aircraft designers are always on the lookout for tough but lightweight materials. Chris Broomell of the University of California, Santa Barbara may have found a new candidate—on the head of a worm. http://louiskjksheehan.blogspot.com
The ragworm, sometimes called the sandworm (but not to be confused with the hideous but fictional creatures from Dune),
boasts two ultra-tough pincers that it uses to burrow into ocean
sediment. At 90 percent protein, you’d expect the worm’s mouth-parts to |
If you
think solar is still too expensive, here’s how to get more bang for your
solar-cell buck. http://louis5j5sheehan5esquire.blogspot.com Take a
small solar cell, and slice it into thin slivers. Wrap the slivers around the
edges of a slab of glass. Paint the glass with a high-tech, but cheap, dye —
which you bought online — and voilà! You have a new solar panel. It can collect
much more energy than the pricey cell you started with, and it costs only a
little more. If done |
Who doesn’t love wireless? http://louiskjksheehan.blogspot.com Surfing the Web while sipping a latte at
your favorite café certainly beats being chained to a modem by a data
cable. But for applications that demand a really fast connection, such
as watching live high-definition television, today’s WiFi falls short.
http://louiskjksheehan.blogspot.com The fastest WiFi available maxes out at 600 million bits per second,
fine for watching a clip from YouTube but far from the billions |
In September, the Topps Meat Company of Elizabeth, New Jersey, issued the second largest beef recall
in U.S. history—21.7 million pounds of ground beef. http://louiskjksheehan.blogspot.comThe recall came
after an investigation, carried out by the New York State Department of
Health and the CDC, linked bacteria from Topps’s frozen ground beef
patties to an outbreak of the O157:H7 strain of E. coli that sickened 40 people in eight states.

Researchers may have found a way to give HIV the finger. http://Louissheehan.BraveDiary.com
Removing immune system cells from mice and treating those
cells with a custom protein called a zinc-finger nuclease in the lab made the
cells resistant to HIV infection, scientists report online and in an upcoming Nature Biotechnology. http://Louissheehan.BraveDiary.com
Injecting those cells back into the animals kept their viral
load limited to less than one-tenth that in |

Black pepper is produced from the still-green unripe berries
of the pepper plant. The berries are cooked briefly in hot water, both
to clean them and to prepare them for drying. The heat ruptures cell walls in the fruit, speeding the work of browning enzymes
during drying. The berries are dried in the sun or by machine for
several days, during which the fruit around the seed shrinks and
darkens into a thin, wrinkled black layer, the result of a fungal
reaction. Once dried, the fruits are |
Sargon of Akkad, also known as Sargon the Great (Akkadian Šarru-kinu, cuneiform ŠAR.RU.KI.IN ????, meaning "the true king" or "the king is legitimate"), was an Akkadian king famous for his conquest of the Sumerian city-states in the 24th and 23rd centuries BC.[1] The founder of the Dynasty of Akkad, Sargon reigned for 56 years, c. 2270 BC – 2215 BC (short chronology).[2] He became a prominent member of the royal court of Kish, ultimately overthrowing its king before embarking on the conquest of |
Myrtle family are a family of dicotyledon plants, placed within the order Myrtales. Myrtle, clove, guava, feijoa, allspice, and eucalyptus belong here. http://louis3j3sheehan3.blogspot.comAll species are woody, with essential oils, and flower parts in multiples of four or five. One notable character of the family is that the phloem is located on both sides of the xylem, not just outside as in most other plants. The leaves are evergreen, alternate to mostly opposite, simple, and usually with an

The Arthur Sack A.S.6 was an experimental German aircraft tested during World War II with an unusual circular planform.
Louis J. Sheehan, Esquire
Arthur Sack was a farmer and aero-model construction enthusiast. In June 1939 in Leipzig-Mockau
he attended the First National Contest of Aero-models with Combustion
Engines, where he hand-launched his first aero model with a circular
wing, the A.S.1.
It possessed rather poor flying qualities. Arthur Sack's aeromodel |

Estimates of proven reserves vary wildly. Most estimates include
only Western Siberian reserves, exploited since the 1970s and supplying
two-thirds of Russian oil, and not potentially huge reserves elsewhere.
Following the collapse of the former Soviet Union, Russia’s oil
output fell sharply, and has rebounded only in the last several years.
Russia reached a peak of 12.5 million barrels per day (1.99×106 m3/d) in total liquids in 1988, but production fell to around |

The success of Silvio Berlusconi's hair transplant, four years ago, relied on the fact that the septuagenarian prime minister had enough of a thatch on the back of his head to enable some of it to be transferred to his thinning top. Although hair transplants have advanced to the stage where they are virtually undetectable (no more plugs of hair), they still rely on moving hairs from one place to another. So, though hairlines such as Mr Berlusconi's can be thickened up, or even straightened,

Have you had learned to eat consciously? Has it changed your life? If not, does it sound like something you'd like to try? Share your thoughts.
Chronic dieters in particular have trouble recognizing their internal cues, says Jean Kristeller, a psychologist at Indiana State, who pioneered mindful eating in the 1990s. "Diets set up rules around food and disconnect people even further from their own experiences of hunger and satiety and fullness," she says.
Mindful eaters learn to assess taste
