Ernest Just
Ernest Everett Just
Born: August 14, 1883
Died: October 27, 1941
Birthplace: Charleston, SC
Ernest Everett Just: Zoologist, Biologist, Physiologist, Research Scientist.
Ernest Everett Just was born in Charleston, South Carolina on August 14, 1883 to parents Charles Frazier and Mary Matthews Just. Ernest's mother decided to send him North to receive better schooling. Through hard work, Ernest was able to earn enough money to attend the Kimball Academy in New Hampshire. The Kimball Academy was an exclusive school and Just proved himself worthy by excelling in his classes. As the editor of the school newspaper and President of the debating team, Ernest completed the four year program in only three, graduating with honors as the valedictorian of his class. He prepared for college at Kimball Hall Academy, New Hampshire, where he completed the four-year course of study in only three years. Learning under the guidance of world famous zoologist William Patten, Just excelled and received degrees in history and biology. In the graduating Dartmouth College class of 1907, Ernest Just was the only person to be graduated magna cum laude. He won special honors in botany and history, with honors in botany and sociology. In his freshman year at Dartmouth he received the highest marks in the entire freshmen class in Greek; Ernest was conferred as the Rufus Choate scholar for two years. In 1907, Dr. Just began to teach at Howard University. Beginning in 1909, he began to conduct research as a research assistant during the summer months for Professor Frank Rattray Lillie, the second director of the Marine Biological Laboratory at Woods Hole, Massachusetts. In 1916, Ernest Just received the Degree of Doctor of Philosophy magna cum laude from the University of Chicago in experimental embryology, with a thesis on the mechanics of fertilization.
Contributions on the physiology of development were the legacy of Dr. Just s research. His work on the subjects of fertilization, experimental parthenogenesis, hydration, cell division, dehydration in living cells, the effect of ultra violet rays in increasing chromosome number in animals and in altering the organization of the egg with special reference to polarity. Ernest Just died on October 27, 1941 of cancer, leaving behind a wife, Ethel, and three children. He also left behind a world which would eventually recognize him as the most outstanding zoologist of his time.

Who Knew !
Small domesticated dogs probably originated in the Middle East more than 12,000 years ago as the descendants of grey wolves, according to a gene study published on Wednesday.
University of California at Los Angeles researchers Melissa Gray and Robert Wayne led a team that searched for variations of a gene called IGF1 which is a characteristic of small dogs.
"(The variant) probably arose early in their history," said Gray, whose paper is published online by BMC Biology, an open-access journal.
"Our results show that the version of the IGF1 gene found in small dogs is closely related to that found in Middle Eastern wolves and is consistent with an ancient origin."
The work concurs with archaeological work in the Middle East that has unearthed the remains of small domestic dogs dating to 12,000 years ago. Digs in Europe have uncovered older remains, to as much as 31,000 years ago, but these are of larger dogs.
Canine selection may have been carried out by villagers in the Fertile Crescent of modern-day Iraq and other cradles of agriculture.
"Small size could have been more desirable in more densely-packed agrarian societies where dogs may have lived partly indoors or in confined outdoor spaces," says the study.

eARTHqUAKE in CHILE
The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said Monday. The quake, the seventh strongest earthquake in recorded history, hit Chile Saturday and should have shortened the length of an Earth day by 1.26 milliseconds, according to research scientist Richard Gross at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Perhaps more impressive is how much the quake shifted Earth's axis," NASA officials said in a Monday update. The computer model used by Gross and his colleagues to determine the effects of the Chile earthquake effect also found that it should have moved Earth's figure axis by about 3 inches (8 cm or 27 milliarcseconds). The Earth's figure axis is not the same as its north-south axis, which it spins around once every day at a speed of about 1,000 mph (1,604 kph).
The figure axis is the axis around which the Earth's mass is balanced. It is offset from the Earth's north-south axis by about 33 feet (10 meters). Strong earthquakes have altered Earth's days and its axis in the past. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami, should have shortened Earth's days by 6.8 microseconds and shifted its axis by about 2.76 inches (7 cm, or 2.32 milliarcseconds). One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond. It increases in the winter, when the Earth rotates more slowly, and decreases in the summer, Gross has said in the past. The Chile earthquake was much smaller than the Sumatran temblor, but its effects on the Earth are larger because of its location. Its epicenter was located in the Earth's mid-latitudes rather than near the equator like the Sumatran event.The fault responsible for the 2010 Chile quake also slices through Earth at a steeper angle than the Sumatran quake's fault, NASA scientists said. "This makes the Chile fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis," NASA officials said.
Gross said his findings are based on early data available on the Chile earthquake. As more information about its characteristics are revealed, his prediction of its effects will likely change.
The Chile earthquake has killed more than 700 people and caused widespread devastation in the South American country.
Several major telescopes in Chile's Atacama Desert have escaped damage, according to the European Southern Observatory managing them.

Fat America
The anger about Benjamin wasn't the only example of vitriol hurled at the overweight. Cintra Wilson, style columnist for The New York Times, recently wrote a column so disdainful of JCPenney's plus-size mannequins that the Times' ombsbudman later wrote that he could read "a virtual sneer" coming through her prose. A NEWSWEEK post about Glamour’s recent plus-size model (in fact, a normal-sized woman with a bit of a belly roll) had several commenters lashing out at the positive reaction the model was receiving. "This model issue is being used as a smoke screen to justify self-destructive lifestyle that cost me more money in health care costs," one wrote. Heath guru MeMe Roth has made a career crusading against obesity, and made waves when she suggested that American Idol contestant Jordin Sparks needed to lose weight. (That MeMe Roth is considered something of an extremist doesn't stop the media attention) Virtually any news article about weight that is posted online garners a slew of comments from readers expressing disgust that people let their weight get so out of control. The specific target may change, but the words stay the same: Self-destructive. Disgusting. Disgraceful. Shameful. While the debate rages on about obesity and the best ways to deal with it, the attitudes Americans have toward those with extra pounds are only getting nastier. Just why do Americans hate fat people so much?
Fat bias is nothing new. "Public outrage at other people's obesity has a lot to do with America from the turn of the 20th century to about World War I," says Deborah Levine, assistant professor of health policy and management at Providence College. The rise of fat hatred is often seen as connected to the changing American workplace; in the early 20th century, companies began to offer snacks to employees, white-collar jobs became more prominent, and fewer people exercised. As thinness became rarer, says Peter N. Stearns, author of Fat History: Bodies and Beauty in the Modern West and professor of history at George Mason University, it was more prized, and conversely, fatness was more maligned.

weekend post News & Media
Port-au-Prince, Haiti (CNN) -- A man pulled alive from the rubble of a building in Haiti's capital Monday may have been trapped since the January 12 quake that leveled much of the city, doctors reported.
The 28-year-old man, identified as Evan Muncie, was found in the wreckage of a market where he sold rice, his family told staff at a University of Miami field hospital. He suffered from extreme dehydration and malnutrition, but did not appear to have significant crushing injuries, the doctors said.
"He was emaciated. He hadn't had anything in quite some time. He had open wounds that were festering on both of his feet," said Dr. Mike Connelly, of the university's Project Medishare.
The people who brought him to the hospital said they found the man while digging out the marketplace, Connelly said.
What is happening in Hati is sad and unexplainable. No one seen this coming and i wish all families the best
