• 06:00 A mineral way to catalysis?

  Read the story at EurekAlert
  Catalytic materials, which lower the energy barriers for chemical reactions, are used in everything from the commercial production of chemicals to catalytic converters in car engines. However, with current catalytic materials becoming increasingly expensive, scientists are exploring viable alternatives.

• 06:00 Authors with financial conflicts reporting negative outcomes in major orthopaedic journals

  Read the story at EurekAlert
  Papers published in orthopaedic journals by authors with a conflict of interest were equally likely to report negative results as those authored by researchers without conflicts, according to new research presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons.

• 06:00 Curry spice component may help slow prostate tumor growth

  Read the story at EurekAlert
  Curcumin, an active component of the Indian curry spice turmeric, may help slow down tumor growth in castration-resistant prostate cancer patients on androgen deprivation therapy, a study from researchers at Jefferson's Kimmel Cancer Center suggests.

• 06:00 Domestic consumption main contributor to Africa's growing E-waste

  Read the story at EurekAlert
  West Africa faces a rising tide of E-waste generated by domestic consumption of new and used electrical and electronic equipment, according to a new United Nations report. Domestic consumption makes up the majority (up to 85 percent) of waste electronic and electrical equipment produced in the region, according to the study. The E-waste problem in West Africa is further exacerbated by an ongoing stream of used equipment from industrialized countries, significant volumes of which prove unsuitable for reuse.

• 06:00 Drug halts organ damage in inflammatory genetic disorder

  Read the story at EurekAlert
  A new study shows that Kineret (anakinra), a medication approved for the treatment of rheumatoid arthritis, is effective in stopping the progression of organ damage in people with neonatal-onset multisystem inflammatory disease. This rare and debilitating genetic disorder causes persistent inflammation and ongoing tissue damage. The research was performed by scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, part of the National Institutes of Health.

• 06:00 EEG pattern reflects brain's shift into low-energy, protective mode

  Read the story at EurekAlert
  A distinctive pattern of brain activity associated with conditions including deep anesthesia, coma and congenital brain disorders appears to represent the brain's shift into a protective, low-activity state in response to reduced metabolic energy.

• 06:00 Grass to gas: UGA researchers' genome map speeds biofuel development

  Read the story at EurekAlert
  Researchers at the University of Georgia have taken a major step in the ongoing effort to find sources of cleaner, renewable energy by mapping the genomes of two originator cells of Miscanthus x giganteus, a large perennial grass with promise as a source of ethanol and bioenergy.

• 06:00 Hovering not hard if you're top-heavy, NYU researchers find

  Read the story at EurekAlert
  Top-heavy structures are more likely to maintain their balance while hovering in the air than are those that bear a lower center of gravity, researchers at NYU's Courant Institute of Mathematical Sciences and Department of Physics have found. Their findings are counter to common perceptions that flight stability can be achieved only through a relatively even distribution of weight -- and may offer new design principles for hovering aircraft.

• 06:00 Molecular profiling reveals differences between primary and recurrent ovarian cancers

  Read the story at EurekAlert
  There is a need to analyze tumor specimens at the time of ovarian cancer recurrence, according to a new study published in Molecular Cancer Therapeutics. Researchers used a diagnostic technology called molecular profiling to examine the differences in the molecular characteristics of primary and recurrent ovarian tumors and found significant changes for some biomarkers.

• 06:00 Neurologic improvement detected in rats receiving stem cell transplant

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report that early transplantation of human placenta-derived mesenchymal stem cells into the lateral ventricles of neonatal rats with birth-related brain damage is possible, and that the donor cells can survive and migrate in the recipient's brain. The study was designed to have the rat's brain damage mimic brain injury in infants with very low birth weight.

• 06:00 New drugs schedule makes horse racing a sure thing

  Read the story at EurekAlert
  QUT professor of biosciences, Martin Sillence, said the new research pinpointed the length of time it took for 18 of the most commonly used therapeutic drugs to work their way out of a horse's system, providing greater certainty for horse owners, trainers and vets."Because horses are prohibited from racing with any trace of drugs in their system, the administration of therapeutic drugs to horses in need of care has been a risky business," professor Sillence said.

• 06:00 New understanding of DNA repair could eventually lead to cancer therapy

  Read the story at EurekAlert
  A research group in the Faculty of Medicine & Dentistry at the University of Alberta is hoping its latest discovery could one day be used to develop new therapies that target certain types of cancers.

• 06:00 Night, weekend delivery OK for babies with birth defects

  Read the story at EurekAlert
  Weekday delivery is no better than night/weekend delivery for infants with birth defects, according to a new study. Researchers found that infants with birth defects that were delivered at night or over the weekend fared just as well as those delivered on a weekday -- they stayed at the hospital for the same amount of time, were admitted to the NICU at the same rate, and were given antibiotics or got help breathing just as often.

• 06:00 No entry without protein recycling: RUB researchers discover new coherence in enzyme transport

  Read the story at EurekAlert
  The group of professor Dr. Ralf Erdmann at the Ruhr-Universitaet Bochum discovered a connection of peroxisomal protein import and receptor export. In the Journal of Biological Chemistry, they disclosed that enzymes only get imported into certain cell organelles (peroxisomes) upon coupling of their import to the recycling of their transport protein (receptor).

• 06:00 Numeracy: The educational gift that keeps on giving?

  Read the story at EurekAlert
  Cancer risks. Investment alternatives. Calories. Numbers are everywhere in daily life, and they figure into all sorts of decisions. A new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, examines how people who are numerate -- that's like literacy, but for numbers -- understand numbers better and process information differently so that they ultimately make more informed decisions.
