Ask your kid what happened to the dinosaurs, and he or she will likely tell you that an asteroid killed them all. But ask how dinosaurs rose to prominence and you'll likely get a blank stare. Even many paleontologists may have little to say about the subject. But now, as EARTH explores in a feature in the February issue, new fossil discoveries are revealing the backstory of the rise of dinosaurs.

New technology providing the first view of DNA damage throughout the entire human genome developed by Cardiff University scientists could offer a valuable new insight into the development and treatment of conditions like cancer.
Professor Ray Waters, Dr Simon Reed and Dr Yumin Teng from Cardiff University's Department of Genetics, Haematology and Pathology have developed a unique way of measuring DNA damage frequency using tiny microarrays.
Soy protein's ability to lower total and LDL (low-density lipoprotein or "the bad") cholesterol has been extensively studied, but the mechanism whereby soy protein lowers cholesterol remains unresolved. A new study published in the Journal of Clinical Lipidology last month shows that soy protein lowers total cholesterol and non-HDL (non-high-density lipoprotein) cholesterol significantly more than milk protein in patients with moderately high cholesterol levels.
EAST LANSING, Mich. — Researchers have identified how the hormones progesterone and estrogen interact to increase cell growth in normal mammary cells and mammary cancers, a novel finding that may explain why postmenopausal women receiving hormone replacement therapy with estrogen plus progestin are at increased risk of breast cancer.
A new study in the Journal of Consumer Research shows that women are better than men at figuring out unusual products when they're among competing items.
"A lot of times when we look at how consumers respond to innovative change in a product's physical form, we fail to consider that the context where they see the product plays a major role in how they evaluate and interpret it," write authors Theodore J. Noseworthy, June Cotte, and Seung Hwan (Mark) Lee (all University of Western Ontario).
People feel closer to businesses and nonprofits that solicit their advice, but soliciting expectations can distance potential customers, according to a new study in the Journal of Consumer Research.
"Marketers and nonprofits alike regularly solicit input from customers or donors for myriad reasons, most notably to measure consumers' preferences, expectations, and satisfaction," write authors Wendy Liu (USCD) and David Gal (Northwestern University). Interactive media such as Facebook and Twitter are providing even greater opportunities for interaction with customers.
A Letter to the Editor entitled "What should we advise about alcohol consumption?" was recently published by Maurizio Ponz de Leon in Intern Emerg Med.1 Dr.
After a rough day at the office, you might opt for a convenient, pretty restaurant over one with a top-notch menu, according to a new study in the Journal of Consumer Research.
A new study finds that a metabolite commonly elevated in brain cancer and leukemia may promote tumorigenesis by altering the expression of a large number of genes. New research, published by Cell Press in the January 18th issue of the journal Cancer Cell, enhances the understanding of the link between metabolic deregulation and cancer and may help to guide development of new targeted cancer therapies.
The first letter of our childhood surname determines much about our consumer behavior as grownups, according to a new study in the Journal of Consumer Research.
Why are some people more likely than others to wait in line overnight to buy a just-released book or to queue up for the new iPad? "The tendency to act quickly to acquire items such as those above is related to the first letter of one's childhood surname," write authors Kurt A. Carlson (Georgetown University) and Jacqueline M. Conard (Belmont University).
When we don't feel confident about our government, we choose indirect ways of showing support, like buying U.S. based products, according to a new study in the Journal of Consumer Research.
"Today, we can barely watch television for any length of time without hearing about verbal attacks on the government, or a given religion or education system," write authors Keisha M. Cutright (Duke University), Eugenia C. Wu (Cornell University), Jillian C. Banfield (University of Waterloo), Aaron C. Kay (Duke University), and Gavan J. Fitzsimons (Duke University).
At least one in five horses used for leisure are overweight or obese. It's a condition which can lead to laminitis and equine metabolic syndrome.
The pilot study, carried out by The University of Nottingham's School of Veterinary Medicine and Science, showed that rates of obesity among horses are likely to be just as high as they are among people. The results are published online on Monday 17 January 2011 in the journal Veterinary Record.
Scientists at The University of Nottingham have brought cancer cells back under normal control — by reactivating their cancer suppressor genes. The discovery could form a powerful new technology platform for the treatment of cancer of the breast and other cancers.
Breast cancer is diagnosed in about 1.4 million women throughout the world every year, with half a million dying from the disease. A common cause of cancer is when cells are altered or mutated and the body's tumour suppressor genes are switched off.
OAK BROOK, Ill. – Jan. 18, 2011 – A study from researchers in Germany showed that magnetic maneuvering of a modified capsule endoscope in the stomach of healthy volunteers under clinical conditions is safe, well-tolerated, and technically feasible. Maneuverability of the capsule within the stomach was excellent and visualization of the gastric mucosa, the inner lining of the stomach, was satisfactory in the majority of subjects. Apart from a single experiment performed with a supervising flexible gastroscope, this was the first study to use the system in the stomach of healthy subjects.
