Stem cells in urine easy to isolate and have potential for numerous therapies
Could harvesting stem cells for therapy one day be as simple as asking patients for a urine sample? Researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine and colleagues have identified stem cells in urine that can be directed to become multiple cell types.

Exercise is good for you, but it won't cut hot flashes
Exercise has proven health benefits, but easing hot flashes isn't one of them. After participating in a 12-week aerobic exercise program, sedentary women with frequent hot flashes had no fewer or less bothersome hot flashes than a control group. This randomized, controlled study from the MsFLASH Research Network was published today in Menopause, the journal of the North American Menopause Society.

Cleveland Clinic study finds lowest risk treatment for severe carotid and coronary disease
Of the three most common treatment approaches for patients with severe carotid and coronary artery disease, patients who underwent stenting of the carotid artery followed by open heart surgery had the best outcomes, according to a retrospective study from Cleveland Clinic published online today in the Journal of the American College of Cardiology.

Autism symptoms not explained by impaired attention
Two aspects of attention -- reorienting focus and attending to social information -- do not seem to account for the diversity symptoms seen in autistic children, according to new research from Clinical Psychological Science.

BPA exposure disrupts human egg maturation
New research led by Catherine Racowsky, Ph.D., director of the Assisted Reproductive Technologies Laboratory at Brigham and Women's Hospital, shows that exposure to BPA (Bisphenol-A) could be a contributing factor as to why some infertile couples are having difficulty conceiving. The study will be published online on July 31, 2013 in the journal Human Reproduction.

Could planting trees in the desert mitigate climate change?
As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now come up with an environmentally friendly method that they say could do just that. The technique, dubbed carbon farming, consists in planting trees in arid regions on a large scale to capture CO2. They publish their study today in Earth System Dynamics, a journal of the European Geosciences Union.

'Highway from hell' fueled Costa Rican volcano
In a new study in the journal Nature, scientists suggest that the 1960s eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought.

How do student characteristics predict university graduation odds?
While policymakers often blame university systems for low graduation among college students, according to new research, characteristics known about a student before he or she even enters a college classroom can accurately predict graduation rates. This new study, published in SAGE Open, finds that characteristics such as full-time enrollment status, race, transfer credits, and expected family contribution predict successful graduation from college.

Bird brains predate birds themselves
New research provides evidence that dinosaurs evolved the brainpower necessary for flight well before they actually took to the air as birds. Based on computed tomographic scans, the study, published today in Nature, takes a comprehensive look at the so-called "bird brain," revealing that at least a few non-avian dinosaurs had brains that were as large or larger than that of one of the earliest known birds, Archaeopteryx.

Digest this: Cure for cancer may live in our intestines

Polar ecosystems acutely vulnerable to sunlight-driven tipping points
Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor. The research from the University of New South Wales and the Australian Antarctic Division predicts biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm. The study will be published in the journal Global Change Biology.

UCLA and Chinese scientists analyze genetic makeup of human and mouse embryos in amazing detail
UCLA scientists and Chinese collaborators have used the powerful technology of single-cell RNA sequencing to track the genetic development of a human and a mouse embryo at an unprecedented level of accuracy. The success of this technique could lead to genetic diagnoses of diseases with higher resolution and in embryos earlier than ever achieved before, even when the embryo consists of only eight cells.

Genome Biology
Ancient viruses that function in early human development may play role in cancer
The St. Laurent Institute published a study in Genome Biology showing that novel non-coding parts of the human genome known as vlincRNAs (very long intergenic, non-coding RNAs) triggered by ancient viruses, participate in the biology of stem cells, and in the development of cancer. Importantly, the group of researchers from US, Europe and Russia found that the elimination of these vlincRNAs caused the death of cancer cells.
