For the most common form of childhood eye cancer, unilateral retinoblastoma, shortening the time from the first appearance of symptoms to diagnosis of disease has no bearing on survival or stage of the disease, according to a study by researchers at Columbia University Mailman School of Public Health in partnership with the Hospital Infantil de Mexico. The results appear online in the journal Cancer Epidemiology, Biomarkers & Prevention.

DALLAS, March 18, 2014 — When a heart gets damaged, such as during a major heart attack, there's no easy fix. But scientists working on a way to repair the vital organ have now engineered tissue that closely mimics natural heart muscle that beats, not only in a lab dish but also when implanted into animals. They presented their latest results at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.

The talk was one of more than 10,000 being presented at the meeting, which continues here through Thursday.

PHOENIX, Ariz. — March 17, 2014 — Using genomic analysis to study cancer in dogs can help develop new therapies for humans with cancer, according to a proof-of-concept study led by the National Cancer Institute (NCI) and the Translational Genomics Research Institute (TGen).

A new UBC study reveals that corporate leaders are victims of herd mentality when adopting new innovations, sometimes with deadly consequences.

The paper, by Sauder School of Business Associate Professor Marc-David L. Seidel and INSEAD Professor Henrich R. Greve, shows leaders tend to pursue innovations, even as complex as airplanes, based on early adoption by competitors not close scrutiny of the technical merits.

PITTSBURGH, Mar.14, 2014 – A structured, standardized approach to diagnose and treat sepsis in its early stages did not change survival chances for people who develop this deadly condition, according to a national, randomized clinical trial led by experts at the University of Pittsburgh School of Medicine.

A recent study by a University of Northern British Columbia-based scientist associated with the UBC Faculty of Medicine and UNBC's Northern Medical Program demonstrates that Canada's drinking-age laws have a significant effect on youth mortality.

Trading food involves the trade of virtually embedded water used for production, and the amount of that water depends heavily on the climatic conditions in the production region: It takes, for instance, 2.700 liters of water to produce 1 kilo of cereals in Morocco, while the same kilo produced in Germany uses up only 520 liters. Analyzing the impact of trade on local water scarcity, our scientists found that it is not the amount of water used that counts most, but the origin of the water.

Researchers at Case Western Reserve University and colleagues used "big data" analytics to predict if a patient is suffering from aggressive triple-negative breast cancer, slower-moving cancers or non-cancerous lesions with 95 percent accuracy.

Adult survivors of childhood cancer face significant health problems as they age and are five times more likely than their siblings to develop new cancers, heart and other serious health conditions beyond the age of 35, according to the latest findings from the world's largest study of childhood cancer survivors. St. Jude Children's Research Hospital led the research, results of which appear in the March 17 issue of the Journal of Clinical Oncology.

Of thousands of known species of Drosophila fruit flies, just one is known as a crop pest, depositing eggs inside ripening fruit so its maggots can feed and grow. New research from the University of California, Davis, shows the similarities and crucial differences between this pest and its close relatives — and that one related fly has potential to also become a pest.

An ultrasound of the lungs could help doctors quickly determine if a pregnant woman with preeclampsia is at risk for respiratory failure, suggests preliminary research published in the April issue of Anesthesiology.

Although cardiac arrest during childbirth is rare, it may be two times more common than previously reported in the literature, suggests the first large U.S. study on the potentially deadly condition published in the April issue of Anesthesiology. The study, based on data for more than 56 million births, also found that cardiopulmonary resuscitation (CPR) was often successful, and that the survival rate improved between 1998 and 2011.

Germany, Austria and Cuba have at least one thing in common: they have all experienced what it means to be 'left out in the cold' and be considered 'bad company' by Western powers. However, just as Iran and South Africa, these three countries have handled this form of stigmatization very differently. According to new research, the reason for this is that diplomatic pressure and sanctions by the international community (the 'shaming method' ) fail to have the intended effect because isolation and shaming may boost national pride and sense of cohesion and thus support the regime in power.

More than 40 percent of pregnant low-income women discharged from the hospital after a diagnosis of false or early labor did not want to be sent home, with the most common reasons being that they were in too much pain or lived too far away, according to a study by Baylor University's Louise Herrington School of Nursing (LHSON) and Parkland Health & Hospital System.

A 39-year study of wildflower blooms in a Colorado Rocky Mountain meadow shows that more than two-thirds of alpine flowers have changed their blooming patterns in response to climate change.

Not only are half the flowers beginning to bloom weeks earlier, but more than a third are reaching their peak blooms earlier, and others are producing their last blooms later in the year.

The blooming season, which used to run from late May through early September, now lasts from late April to late September, according to University of Maryland ecologist David Inouye.
