Scientists in Connecticut have carried out one of the first psychological studies into eating disorders in Native American (NA) populations. The research, published in The International Journal of Eating Disorders, provides new insights into the extent to which Native American populations experience eating disorders, revealing that women are more likely to report behavioral symptoms then men, while challenging views that NA men and ethnically white men will experience different psychological symptoms.
For the first time, researchers have developed a 3D picture of a herpes virus protein interacting with a key part of the human cellular machinery, enhancing our understanding of how it hijacks human cells to spread infection and opening up new possibilities for stepping in to prevent or treat infection. This discovery uncovers one of the many tactical manoeuvres employed by the virus.
AMES, Iowa – An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas.
John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates.
Scientists have discovered direct evidence of the diet of one of the most important group of ammonites, distant relatives of squids, octopuses and cuttlefishes. The discovery may bring a new insight on why they became extinct 65.5 million years ago, at the end of the Cretaceous.
If you want to be surrounded by females on the prowl, it pays to be cool, at least if you are a male butterfly.
Madison, WI December 28, 2010 – The Australian Government National Water Commission funded a study to establish an approach to assess the quality of water treated using managed aquifer recharge. Researchers at Australia's CSIRO Land and Water set out to determine if the en product would meet standard drinking water guidelines.
(PHILADELPHIA) Elevated fat and cholesterol levels found in a typical American-style diet play an important role in the growth and spread of breast cancer, say researchers at the Kimmel Cancer Center at Jefferson.
In a groundbreaking achievement that could help scientists "build" new biological systems, Princeton University scientists have constructed for the first time artificial proteins that enable the growth of living cells.
The team of researchers created genetic sequences never before seen in nature, and the scientists showed that they can produce substances that sustain life in cells almost as readily as proteins produced by nature's own toolkit.
Medical researchers who crave a means of exploring the genetic culprits behind a host of neuromuscular disorders may have just had their wish granted by a team working at the National Institute of Standards and Technology (NIST), where scientists have performed surgery on single cells to extract and examine their mitochondria.
As the day draws nearer for the world to run out of the unique addresses that allow us to use the Internet—now predicted to happen by the end of 2012—researchers at the National Institute of Standards and Technology (NIST) have issued a guide for managers, network engineers, transition teams and others to help them deploy the next generation Internet Protocol (IPv6) securely.
Two new draft publications from the National Institute of Standards and Technology (NIST) provide the groundwork for a three-tiered risk-management approach that encompasses computer security risk planning from the highest levels of management to the level of individual systems. The draft documents have been released for public comment.
Most of the time cancer seems to creep up gradually over time; cells become premalignant, then increasingly abnormal before they become cancerous. But sometimes cancers seem to pop up as if out of nowhere. Now, researchers reporting in the January 7th issue of the journal Cell, a Cell Press publication, have new evidence to explain how that can happen. Based on the DNA sequences of multiple cancer samples of various types, they show that cancer can arise suddenly in the aftermath of one-off cellular crises involving tens to hundreds of genomic rearrangements.
Using a new technology that relies on thousands of synthetic molecules to fish for disease-specific antibodies, researchers have developed a potential method for detecting Alzheimer's disease with a simple blood test. The same methodology might lead to blood tests for many important diseases, according to the report in the January 7th issue of the journal Cell, a Cell Press publication.
