• 06:00 New test announced for major killer of lung transplant patients

  Read the story at EurekAlert
  A lung transplant can mean a new chance at life. But many who receive one develop a debilitating, fatal condition that causes scar tissue to build up in the lungs and chokes off the ability to breathe.University of Michigan researchers hope a new diagnostic tool they developed to predict bronchiolitis obliterans syndrome will allow doctors to intervene earlier and, ultimately, to provide life-saving treatments.

• 06:00 What triggers mass extinctions? Study shows how invasive species stop new life

  Read the story at EurekAlert
  An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published today in the journal PLoS ONE.The study of the collapse of Earth's marine life 378 to 375 million years ago suggests that the planet's current ecosystems, which are struggling with biodiversity loss, could meet a similar fate.

• 06:00 April grafting optimal for Fraser fir

  Read the story at EurekAlert
  Christmas trees provide a significant source of revenue in southern Appalachia. The most popular species in the region is Fraser fir but they are under attack by a pathogen that causes root rot, kills seedlings, and threatens serious economic losses. To develop planting stock that is resistant to or tolerant of the pathogen, researchers are comparing success rates of the traditional April grafting time with eight summer/early fall grafting dates.

• 06:00 Can bedding plants thrive with recyled water?

  Read the story at EurekAlert
  To conserve dwindling water resources, municipalities are encouraging the use of "recycled water," municipal wastewater that has been extensively treated and deemed safe to reuse for irrigation and other purposes. New research from Texas A&M University provides bedding plant growers with important data about ten common species/cultivars. For the study, bedding plants were irrigated with saline solution to simulate the composition of local reclaimed water.

• 06:00 Children in areas with few pediatricians at higher risk for serious appendix ruptures

  Read the story at EurekAlert
  Children who live in areas with fewer pediatricians are more likely to suffer life-threatening ruptures of the appendix than those in areas with more pediatricians, even when accounting for other factors such as the number of hospitals, imaging technology, insurance coverage and the number of surgeons in an area, according to a study from the Johns Hopkins Children's Center.

• 06:00 Coma and general anesthesia demonstrate important similarities

  Read the story at EurekAlert
  The brain under general anesthesia isn't "asleep" as surgery patients are often told -- it is placed into a state that is a reversible coma, according to three neuroscientists who have published an extensive review of general anesthesia, sleep and coma, in the Dec. 30 issue of the New England Journal of Medicine. This insight and others reported in their review article could eventually lead to new approaches to general anesthesia and improved diagnosis and treatment for sleep abnormalities and emergence from coma.

• 06:00 Doctors should be required to disclose sleep deprived status to patients before elective surgeries

  Read the story at EurekAlert
  While regulations have been put in place to restrict the work hours of doctors in training, no such regulations exist for fully trained physicians. An editorial in this week's New England Journal of Medicine argues that sleep-deprived physicians should not be permitted to proceed with an elective surgery without a patient's informed, written consent.

• 06:00 Hybrid string blossom thinner tested in peach orchards

  Read the story at EurekAlert
  Peach producers have traditionally relied heavily on hand thinning, a necessary but costly and labor-intensive field practice. Researchers in Pennsylvania examined whether a new string thinner prototype designed to thin vase or angled tree canopies could be adapted for varying orchard systems. Field trials demonstrated reduced labor costs compared with hand-thinned controls, and increased crop value due to a larger distribution of fruit in marketable and higher market value sizes.

• 06:00 Improving nitrogen use efficiency lessens environmental impact

  Read the story at EurekAlert
  Most agricultural crops require large quantities of nitrate-rich fertilizer to realize optimal yields. Increased interest in environmentally beneficial "low-input" approaches is challenging researchers to identify genotypes that have a characteristic called "high nutrient use efficiency", or NUE. Using vegetable types with high NUE could help growers lessen environmental impacts while maintaining high crop yields. A new study reported on improved NUE traits that resulted from grafting melon plants onto commercial rootstocks.

• 06:00 Indoor plant intervention: New answers for health care design?

  Read the story at EurekAlert
  Could a plant "intervention" improve the well-being of patients in a difficult rehab process? Scientists from Norway and Sweden found that patients' overall physical and mental health improved during the program, but the presence of new plants did not increase the degree of improvement. However, pulmonary patients in the "plant intervention group" reported a larger increase in well-being during their rehabilitation program more often than lung patients from the "no-plant" control group.
