A study published in Science confirms that Tyrannosaurus rex shares common ancestry with modern-day birds, including chickens and ostriches, based on molecular analysis of ancient protein sequences. This finding provides the first molecular evidence for the evolutionary relationships of a non-avian dinosaur.
Scientists predict that a full ozone hole recovery could modify climate change in the Southern Hemisphere, causing Antarctica to warm like the rest of the world. As stratospheric ozone levels recover, atmospheric circulation patterns and air temperatures above 6 miles high could rise by up to 16 degrees Fahrenheit.
Researchers at CAMH have identified a new gene, CC2D2A, associated with a previously unknown form of intellectual disability characterized by retinitis pigmentosa. The mutation affects protein function, leading to faulty cell activity and the disorder.
New research suggests that injecting sulfate particles into the stratosphere to cool the planet would have a drastic impact on the ozone layer. The study finds that such an approach might delay the recovery of the Antarctic ozone hole by decades and cause significant ozone loss over the Arctic.
A study found that India will account for 60% of the world's heart disease burden by 2010, with a higher rate of severe cases among younger patients. The country also has a lower age at diagnosis compared to developed countries.
A national survey conducted by Kelton Research for the Arnold P. Gold Foundation found that nearly eight out of ten Americans believe doctors need better bedside manners and less than half could describe their doctor's recent conduct as attentive, communicative, or compassionate.
Research published in PLOS Genetics found that hormone-dependent and independent breast cancers originate from distinct genetic variants, suggesting separate biological pathways. This discovery could guide future research into prevention and treatments for the different cancer types.
A new study from the American Cancer Society finds racial disparities in smoking cessation treatment, with black and Hispanic smokers less likely to receive advice and aids. The study also reveals that men and those without a usual source of medical care are less likely to be screened for tobacco use and receive advice to quit.
The COPILOT study found that low-dose peginterferon alfa-2b improved disease-free survival in patients with cirrhosis and portal hypertension, especially those who stayed on treatment. In contrast, the medication was not superior to colchicine in overall patient populations.
