African American chemist Percy Julian

African American chemist Percy Julian Pioneering chemist Percy Julian subject of upcoming NOVA documentary.
The American Chemical Society is hosting a symposium honoring pioneering African American chemist Percy Julian, Ph.D., at its 232nd National Meeting in San Francisco on Sept. 11. The symposium is part of the celebration of Julian, whose life story is the subject of a two-hour PBS/NOVA documentary scheduled to be broadcast on Feb. 6, 2007, during Black History month.

One of the sessions at the symposium -- "Dr. Percy L. Julian Scientist, Humanist, Educator, Entrepreneur, and Inspirational Trailblazer" -- will offer a sneak preview of the documentary, which is entitled, "Forgotten Genius," written and produced by Llewellyn Smith, writer/producer/director of Vital Pictures, Inc.; Steve Lyons, writer/producer of Moreno, Lyons Productions LLC; and Melanie Wallace, senior series producer, NOVA/WGBH.

"Forgotten Genius" is, according to Smith, "a first time portrait of this remarkable American chemist The NOVA documentary brings to the public the forgotten achievements of this 20th century scientist." The film is part of NOVA's Lives in Science series.

Percy Lavon Julian was born in Montgomery, Ala., on April 11, 1899. The son of a railway clerk and the grandson of slaves, his early schooling was spotty in the segregated South of the early 20th century. Even so, he was accepted as a freshman at DePauw University in Greencastle, Ind., at the age of 17; he graduated first in his class in 1920. He then taught for two years at Fisk University before enrolling in a Master's program at Harvard.........

Threat of nuclear terrorism?

Threat of nuclear terrorism?
Nuclear terrorism is the gravest international security challenge today. Is the United States prepared to cope with this very real threat? Is nuclear terrorism preventable? What steps has the U.S. already taken to avoid this catastrophe and what steps should be taken in the future?

Esteemed scholars, scientists, and policymakers address these crucial questions in the September volume of SAGE Publications' The ANNALS of The American Academy of Political and Social Science. All sides of the discussion, from strategic to tactical, from ideological to technical, and from the historical to the contemporary, are explored in this volume, which is edited by Graham Allison of the Belfer Center for Science and International Affairs, John. F. Kennedy School of Government, Harvard University.

This special volume of The ANNALS clarifies and assesses the possibility of a nuclear terrorist attack by taking a comprehensive historical look at this threat over time, while examining and proposing solutions for preventing such a catastrophic event.

"The authors devoutly hope for a future when world leaders recognize this grave danger, taking the actions necessary to defeat it," commented issue editor Graham Allison. "On current trendlines, however, the likelihood of failure is greater than that of success. We hope to remind the world just how horrible nuclear anarchy would be".........

Orange Juice To Keep Kidney Stones Away

Orange Juice  To Keep Kidney Stones Away
A daily glass of orange juice can help prevent the recurrence of kidney stones better than other citrus fruit juices such as lemonade, scientists at UT Southwestern Medical Center have discovered.

The findings indicate that eventhough a number of people assume that all citrus fruit juices help prevent the formation of kidney stones, not all have the same effect. The study is available online and is scheduled would be reported in the Oct. 26 issue of the Clinical Journal of the American Society of Nephrology.

Medically managing recurrent kidney stones requires dietary and changes in lifestyle as well as therapy such as the addition of potassium citrate, which has been shown to lower the rate of new stone formation in patients with kidney stones.

But some patients can't tolerate potassium citrate because of gastrointestinal side effects, said Dr. Clarita Odvina, assistant professor of internal medicine at the Charles and Jane Pak Center for Mineral Metabolism and Clinical Research and the study's lead author. In those cases, dietary sources of citrate such as orange juice may be considered as an alternative to pharmacological drugs.

"Orange juice could potentially play an important role in the management of kidney stone disease and may be considered an option for patients who are intolerant of potassium citrate," Dr. Odvina said.........

Aspirin Might Prevent Prostate Enlargement

Aspirin Might Prevent Prostate Enlargement
Scientists at Mayo clinic have observed that taking non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen may prevent or delay non-malignant prostatic hyperplasia, an enlarged prostate which can cause urinary symptoms in men as they age such as frequent urination, trouble starting urination, awakening frequently at night to urinate, weak urine stream and an urgent need to urinate.

"This study suggests that men's urinary health may be improved by taking NSAIDs," says Michael Lieber, M.D., Mayo Clinic urologist and the lead study investigator. He and co-scientists found the risk of developing an enlarged prostate was 50 percent lower in those who take NSAID in comparison to non-users, and risk of developing moderate to severe urinary symptoms was 35 percent lower, he says.

Jenny St. Sauver, Ph.D., Mayo Clinic epidemiologist and lead study investigator, says, "The association between intake of NSAIDs and the reduction of non-malignant prostatic hyperplasia is strengthened by the consistency and magnitude of our findings. We would not recommend that every man go out and take aspirin, but if they are already taking it regularly for other reasons, our findings suggest another benefit as well".

Non-cancerous prostatic hyperplasia increases as men age, affecting one in four men ages 40 to 50 and almost half of 70- to 80-year-old men. The condition is most often diagnosed when men visit their physicians due to urinary problems that are prompted by the prostate enlargement this condition produces.........

Malpractice Concerns Deter Residents

Malpractice Concerns Deter Residents
The survey results were announced earlier this month at the Florida Obstetric and Gynecological Society (FOGS) annual meeting in West Palm Beach. Aaron Deutsch, MD, lead author of the study and chief resident in the USF Department of Obstetrics and Gynecology, presented the findings. The paper received the 2006 first-place resident research award from FOGS.

"Florida is already a state without enough obstetrician/gynecologists to meet the needs of patients. In some parts of the state, women must wait several months to see an obstetrician, and there are no perinatologists or maternal-fetal medicine specialists to take care of high-risk pregnancies," Dr. Deutsch said. "Our findings suggest this shortage may get even worse".

The USF researchers sent surveys to all fourth-year medical students in Florida in fall 2005. The senior year is when medical students find out where they will conduct their residencies the period of specialized training for licensed medical graduates in their chosen medical field.

Florida mirrors a national trend of fewer medical students applying for ob/gyn residencies. The USF researchers hypothesized that student concerns about the rising cost of malpractice premiums and medical liability in Florida may contribute to the marked decline of students specializing in ob/gyn.........

Ancient Raptors Likely Feasted On Early Man

A new study suggests that prehistoric birds of prey made meals out of some of our earliest human ancestors.

Researchers drew this conclusion after studying more than 600 bones from modern-day monkeys. They had collected the bones from beneath the nests of African crowned eagles in the Ivory Coast's Tai rainforest. A full-grown African crowned eagle is roughly the size of an American bald eagle, which typically weighs about 10 to 12 pounds.

Punctures and scratches on many of the monkey skulls have led some researchers to rethink which animals may have preyed on our human ancestors, said W. Scott McGraw, the study's lead author and an associate professor of anthropology at Ohio State University.

"It seems that raptors have been a selective force in primate evolution for a long time," he said. "Before this study I thought that eagles wouldn't contribute that much to the mortality rate of primates in the forest.

"I couldn't have been more wrong".

The results may also have important implications for the mystery surrounding the death of one human ancestor who lived about 2.5 million years ago.

Archaeologists discovered the skull of a 3½-year old ape-like child in a cave in South Africa in 1924. Researchers believed this child, called the Taung child (Australopithecus africanus), had been killed by a predatory cat. But McGraw said that puncture marks on the monkey skulls he examined closely resemble those found on the skull of the Taung child.........

Biodegradable dinnerware

Biodegradable dinnerware
It's true, I don't host a number of brunches or entertain a lot from home, but if I did, I would definitely get these biodegradable dinnerware sets, not just because they are attractive (call me boring, but I hate paper plates with designs on them, particularly seasonal and holiday themes), but because they are made of 100% biodegradable, compostable sugar cane fiber, and the utensils are made of 80% potato starch and 20% vegetable oil.

Sugar cane fiber is a renewable resource, and these pieces are much sturdier than paper; thus they're "microwavable, freezer safe, oil resistant, and capable of handling hot foods and beverages." Never mind that some people consider using disposable dinnerware tacky when entertaining (maybe it's a cultural thing, but I grew up using paper plates at every family gathering), but if you'd rather use your fine china when guests are over, consider these the next time you're planning a picnic.........

Sparganium Erectum

Sparganium Erectum
Thanks again to marcella2@Flickr for sharing a photograph (original image | BPotD Flickr Group Pool). The last time a photograph from marcella2@Flickr was featured on BPotD, over three dozen images of plants were available by clicking on the marcella2@Flickr link - now there's over five dozen, so you might like to revisit them.

I should first of all note that I've changed the name of the plant posted by marcella2 from Sparganium ramosum to the catch-all Sparganium erectum (a number of Sparganium are listed as being synonymous to Sparganium erectum). I'm following the nomenclature suggested by Missouri Botanical Garden's TROPICOS database, but with reservation. In a conversation with Richard Lansdown ten days ago or so, Richard expressed the opinion that many of the less-examined plants sharing the same name in both Europe and North America are actually quite different from one another. Even the Flora of North America expresses reservation about the nomenclature within this genus, because the last work done on it (in the mid 1980s) did not contain detailed studies of the species across their complete ranges. A grain of salt is required, it seems.

I've an inexplicable soft spot for plants in the genus Sparganium, despite the fact that some have been declared a noxious weed. It may be that the soft spot stems from the exotic appearance - exotic, at least, to someone first learning plants through observing the native plants of Manitoba. I still find them interesting, and I know if I encountered some similar to these, I'd spent quite a bit of time photographing them.........
