| Vaccine linked to 'bleeding calf syndrome' Posted: 29 Aug 2011 06:08 PM PDT New research links bleeding calf syndrome to anti-MHC class I antibodies, produced by the mother in response to contamination of vaccine against Bovine viral diarrhea virus with proteins released by the production process.  |
| Posted: 29 Aug 2011 02:37 PM PDT A team of German and Canadian scientists has shown that today's plague pathogen has been around at least 600 years. The Black Death claimed the lives of one-third of Europeans in just five years from 1348 to 1353. Until recently, it was not certain whether the bacterium Yersinia pestis -- known to cause the plague today -- was responsible for that most deadly outbreak of disease ever.  |
| Putting the squeeze on fruit with 'pascalization' boosts healthful antioxidant levels Posted: 29 Aug 2011 01:46 PM PDT Scientists are reporting new evidence that a century-old food preservation technology, finding a new life amid 21st-century concerns about food safety and nutrition, more than doubles the levels of certain healthful natural antioxidants in fruit. The effect occurs as a bonus in addition to its effects in killing harmful bacteria, viruses and mold in food.  |
| Posted: 29 Aug 2011 12:34 PM PDT How did a bacterium that causes mild stomach irritation rapidly evolve into a deadly assassin responsible for the most devastating pandemics in human history? New DNA sequencing techniques reveal how Yersinia pseudotuberculosis became Yersinia pestis, otherwise know as the plague. The new study offers a glimpse into how the new technology might aid in the development of drugs to fight deadly diseases, including the plague.  |
| How an 'evolutionary playground' brings plant genes together Posted: 29 Aug 2011 12:34 PM PDT Plants produce a vast array of natural products, many of which we find useful for making things such as drugs. Researchers have recently discovered that the genes producing two of these products in the model plant Arabidopsis are clustered together by an 'evolutionary playground' in the plant's genome. Knowing how these clusters assemble and are controlled will be important for improving and exploiting the production of new natural products.  |
| Scientists develop new technologies for understanding bacterial infections Posted: 29 Aug 2011 12:34 PM PDT Understanding how bacteria infect cells is crucial to preventing countless human diseases. In a recent breakthrough, scientists have discovered a new approach for studying molecules within their natural environment, opening the door to understanding the complexity of how bacteria infect people.  |
| Little plant tells big stories: Researchers capture codes to genetic variation in 'model' plant Posted: 29 Aug 2011 08:49 AM PDT An international collaboration of researchers compared genetic data from 19 different strains of a humble plant called Arabidopsis thaliana. The genome sequences of these strains, 18 of which are presented in the study, will now make it easier to study plants' surprisingly wide trait variation that underlies their adaptability.  |
