• 06:00 Study examines quality of life factors at end of life for patients with cancer

  Read the story at EurekAlert
  Better quality of life at the end of life for patients with advanced cancer was associated with avoiding hospitalizations and the intensive care unit, worrying less, praying or meditating, being visited by a pastor in a hospital or clinic, and having a therapeutic alliance with their physician, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

• 06:00 Study finds 'mad cow disease' in cattle can spread widely in ANS before detectable in CNS

  Read the story at EurekAlert
  Bovine spongiform encephalopathy (BSE, or "mad cow disease"), a fatal disease in cattle, causes portions of the brain to turn sponge-like due to propagation of a misfolded protein known as a prion. Previous research has reported that the autonomic nervous system (ANS) becomes affected by the disease only after the central nervous system (CNS) has been infected. Researchers found that the ANS can show signs of infection prior to involvement of the CNS.

  Read the story at EurekAlert
  Rice consumers concerned about reports that rice is linked to diabetes can rest assured that rice can be part of a healthy diet, with scientists finding that the glycemic index of rice varies a lot from one type of rice to another, with most varieties scoring a low to medium GI.

• 06:00 Sustainability of rice landscapes in South East Asia threatened

  Read the story at EurekAlert
  During a meeting in Banaue, the Philippines, scientists from 21 research institutions from Germany, Vietnam, the Philippines, Thailand, UK, Bulgaria and Spain raised several concerns on the future of the rice ecosystems in South East Asia. The meeting was organized within the framework of the international project LEGATO that deals with the multiple risks for rice ecosystems arising from various aspects of global change.

• 06:00 Taking a bird's eye view could cut wildlife collisions with aircraft

  Read the story at EurekAlert
  Using lights to make aircraft more visible to birds could help reduce the risk of bird strikes, new research by the US Department of Agriculture has found. The study, which examined how Canada geese responded to different radio-controlled model aircraft, is the first of its kind and is published in the British Ecological Society's Journal of Applied Ecology.

• 06:00 Technique spots disease using immune cell DNA

  Read the story at EurekAlert
  By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique, described in two recent papers, potentially valuable not only for research but also for diagnostics and treatment monitoring.

• 06:00 Tiny bubbles snap carbon nanotubes like twigs

  Read the story at EurekAlert
  A computer model from Rice University shows that long nanotubes bend and snap like a twig when blasted with ultrasonic energy. The research in the Proceedings of the National Academy of Sciences finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.

• 06:00 Training improves recognition of quickly presented objects

  Read the story at EurekAlert
  "Attentional blink" is the term psychologists use to describe our inability to recognize a second important object if we see it less than half a second after a first one. It always seemed impossible to overcome, but in a new paper in the Proceedings of the National Academy of Sciences, Brown University psychologists report they've found a way.

• 06:00 Triboelectric generator produces electricity by harnessing friction between surfaces

  Read the story at EurekAlert
  Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us -- this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another.

• 06:00 Turning off key piece of genetic coding eliminates toxic effect of statins, SLU research finds

  Read the story at EurekAlert
  In research funded by the National Institutes of Health and the American Heart Association and published in EMBO Molecular Medicine, Saint Louis University investigator Ángel Baldán, Ph.D., found that the microRNA miR-33 plays a key role in regulating bile metabolism. Further, the research suggests that, in an animal model, the manipulation of this microRNA can improve the liver toxicity that can be caused by statins.

  Read the story at EurekAlert
  Despite the ever-louder drumbeat for sustainability and global efforts to advance environmental initiatives, Earth remains on a collision course with "unprecedented levels of damage and degradation." That's according to a new United Nations assessment that includes UC Santa Barbara researchers among its authors.

• 06:00 UNC research: Corals on ocean-side of reef are most susceptible to recent warming

  Read the story at EurekAlert
  Marine scientists at the University of North Carolina at Chapel Hill have linked the decline in growth of Caribbean forereef corals -- due to recent warming -- to long-term trends in seawater temperature experienced by these corals located on the ocean-side of the reef. The research was conducted on the Mesoamerican Barrier Reef System in southern Belize.

• 06:00 Use of drug-eluting stents varies widely; Modestly correlated with coronary artery restenosis risk

  Read the story at EurekAlert
  A study based on more than 1.5 million percutaneous coronary intervention procedures (such as balloon angioplasty or stent placement to open narrowed coronary arteries) suggests that the use of drug-eluting stents varies widely among US physicians, and is only modestly correlated with the patient's risk of coronary artery restenosis (renarrowing), according to a report published online first by Archives of Internal Medicine, a JAMA Network publication.

• 06:00 UTHealth, French researchers discover gene defect for new syndrome

  Read the story at EurekAlert
  Research teams from the University of Texas Health Science Center at Houston and Paris, France have discovered a gene defect linked to a cluster of systemic complications, including life-threatening thoracic aortic disease and intracranial aneurysms. The new syndrome is similar, but distinct from known syndromes such as Marfan and Loeys-Dietz syndrome.

• 06:00 Vaccine and antibiotics stabilized so refrigeration is not needed -- NIH study

  Read the story at EurekAlert
  Researchers funded by the National Institutes of Health have developed a new silk-based stabilizer that, in the laboratory, kept some vaccines and antibiotics stable up to temperatures of 140 degrees Fahrenheit. This provides a new avenue toward eliminating the need to keep some vaccines and antibiotics refrigerated, which could save billions of dollars every year and increase accessibility to third world populations.
