'Cosmic ghost' discovered by volunteer astronomer
When Yale astrophysicist Kevin Schawinski and his colleagues at Oxford University enlisted public support in cataloguing galaxies, they never envisioned the strange object Hanny van Arkel found in archived images of the night sky.

Duck-billed dinosaurs outgrew predators to survive
With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in size.

Adults who eat eggs for breakfast lose 65 percent more weight
A study published online today in the International Journal of Obesity shows that eating two eggs for breakfast, as part of a reduced-calorie diet, helps overweight adults lose more weight and feel more energetic than those who eat a bagel breakfast of equal calories.

Metabolic insight to illuminate causes of iron imbalance
New insight into key players in iron metabolism has yielded a novel tool for distinguishing among root causes of iron overload or deficiency in humans, the researchers report in the August issue of Cell Metabolism, a publication of Cell Press. While the body needs iron to produce hemoglobin, a substance in red blood cells that enables them to carry oxygen, too much iron can build up and eventually damage organs.

NASA data show some African drought linked to warmer Indian Ocean
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region's food security.

Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women affected by the condition.

Key site in iron metabolism aids in diagnosing anemia of chronic disease
University of Utah School of Medicine researchers have developed a new tool that facilitates diagnosis of anemia related to chronic illness, as well as diseases of iron overload. The results of a study detailing the new tool are published in the August 2008 issue of the journal Cell Metabolism, a publication of Cell Press.

Medicinal marijuana effective for neuropathic pain in HIV
In a double-blind, placebo-controlled clinical trial to assess the impact of smoked medical cannabis, or marijuana, on the neuropathic pain associated with HIV, researchers at the University of California, San Diego School of Medicine found that reported pain relief was greater with cannabis than with a placebo.

Context and personality key in understanding responses to emotional facial expressions
It is well appreciated that facial expressions play a major role in non-verbal social communication among humans and other primates, because faces provide rapid access to information about the identity as well as the internal states and intentions of others.

Post-partum suicide attempt risks studied
Although maternal suicide after giving birth is a relatively rare occurrence, suicide attempts often have long-lasting effects on the family and the infant. In a study published in the August 2008 issue of the American Journal of Obstetrics & Gynecology, researchers compared two populations of mothers and found that a history of psychiatric disorders or substance abuse was a strong predictor of post-partum suicide attempts.

Students with food allergies often not prepared
College students with food allergies aren't avoiding the foods they know they shouldn't eat. Students of all ages are not treated with potentially life-saving epinephrine as often as they should be. And instructors, roommates and friends often are not aware of what to do if a food-allergic student has a reaction.

Targeted drug therapy found effective in patients with common form of immune-mediated kidney disease
The drug rituximab causes considerable kidney injury healing in patients with membranous nephropathy, a common form of kidney disease, according to a study appearing in the November 2008 issue of the Clinical Journal of the American Society Nephrology (CJASN). The results suggest that this condition, previously destined to progress to kidney failure in 30-40 percent of cases, can actually be healed in some patients.

When neurons fire up: Study sheds light on rhythms of the brain
In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this random synchronization.

Back to the Future: Psychologists examine children's mental time traveling abilities
Planning and anticipating occur so frequently in our everyday lives that it is hard to imagine a time when we didn't have this capability. But just as many other capacities develop, so does this mental time traveling ability. Researchers have recently explored how children comprehend the future and ways that this understanding can be affected by, for example, their current physiological state.
