Dust To Dust: Particles Could Affect Entire Earth, Paper Says
You probably consider those dust particles that make you sneeze and wheeze a nuisance, but those tiny pieces of matter could potentially affect the world's climate, its oceans and even the food chain process, note the authors of a paper appearing in this week's Science magazine. Evolution Of Crop Grasses Linked To Greenhouse Gases
Evolutionary biologists provide strong evidence that changes in global carbon dioxide levels probably had an important influence on the emergence of a specific group of plants, termed C4 grasses. These grasses include major cereal crops, plants used for biofuels, and species that represent important components of grasslands across the world. Facelift Alternatives Rid Patients Of Neck 'Wattle' Without The Downti
Many people want to rid themselves of neck "wattle"to look younger or to wear certain clothes or accessories more comfortably, without having facelifts. Patients have less invasive options to rid the "wattle,"reports a study in May's Plastic and Reconstructive Surgery, through targeted neck rejuvenation techniques. Women &The Sea
This site traces the relationship of females to the sea, from female figureheads on ships and mermaids to women in the military, in yachting and racing, and as ship captains. Includes a timeline (1493-1995), images, bibliography, and links to related sites. From the Mariners' Museum, Newport News, Virginia. Muskox Suffered Loss Of Genetic Diversity At Pleistocene/Holocene Tran
The tundra muskox, one of the few large northern mammals to have survived to thepresent day, saw its genetic diversity decrease greatly at the end of thePleistocene period, around 10,000 years ago. A study published in the openaccess journal BMC Evolutionary Biology reveals that the muskox (Ovibusmoschatus) was genetically much more diverse before the Pleistocene/Holocenetransition, the period that witnessed the extinction of other great mammals suchas the mammoth. Researchers Identify Gene Found In Two Of Five Breast Cancer Patients
A team at the Cancer Centre at McGill University has uncovered the role played by a gene associated with the propagation of breast cancer in two of five affected women. Their study, published in the magazine Nature Genetics, shows that halting the activity of this gene in mice predisposed to cancer slowed the growth of -- and in some cases, prevented -- tumors. A Nagasaki Report
On-the-scene reporting of Nagasaki, written in September, 1945 by American George Weller, "the first foreign reporter to enter Nagasaki following the U.S. atomic attack."Copies of these stories, originally censored by U.S. occupation forces, were discovered after among Weller's effects after his death in 2002. From the Mainichi Daily News, Japan. Research Pinpoints West Nile Virus Antibody Binding Site
Researchers have learned the precise location where an antibody binds to the West Nile virus, and they have suggested a mechanism for how this antibody neutralizes the virus to prevent infection. Be A Control Freak: Allergists Outline New Focus For Asthmatics
A Mayo Clinic allergist and colleagues representing the American Academy of Allergy, Asthma &Immunology and the American College of Allergy, Asthma and Immunology announce they are revising the old classification of asthma patients by disease severity to determine treatment and moving to a new expectation for all asthma patients: excellent symptom control. Watching The Birth And Death Of Exotic Molecules
Researchers from Korea, Italy, France and the ESRF have just observed how a molecule changes structure after being hit with a short flash of laser light. Thanks to very intense pulses of X-rays from the synchrotron and novel data analysis, they were able to confirm a long standing hypothesis regarding the evolution of this molecule. The results are published in Science Express of 14 July.
