EARTH: Unearthing Antarctica's mysterious mountains
2012-02-08
(Press-News.org) Alexandria, VA – Buried more than a kilometer beneath the East Antarctica Ice sheet, the Gamburstev Subglacial Mountains have proven to be a geological puzzle for more than 5 decades. How did these mountains form? When did they form? And what makes this ancient mountain range one of the least-understood tectonic features on Earth?
The Gamburstevs lie under the highest point in Antarctica: the 4,000-meter-high Dome Argus Plateau. The mountain range, in the middle of an ancient continental craton, has a thick, crustal root and high topography. Locked under the ice, frozen in time, what secrets could the Gamburstevs reveal about the evolution of our planet? Look below the ice and read the rest of the story available online here http://www.earthmagazine.org/article/unearthing-antarcticas-mysterious-mountains.

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) highlights the benefits of total knee replacement (TKR) in elderly patients with osteoarthritis, including a lower probability of heart failure and mortality.
Investigators reviewed Medicare records to identify osteoarthritis patients, separating them into two groups – those who underwent TKR to relieve symptoms, and those who did not. Outcomes of interest included average annual Medicare payments for related care, mortality, and new diagnoses of congestive heart failure, ...

Workers' compensation has become part of the fabric of the employer-employee relationship in North Carolina and across the U.S. In essence, an employer purchases insurance to cover the cost of work-related employee injuries and illnesses. This mandated coverage replaces the uncertainty of an employee having to sue his or her employer for work-related medical expenses and lost wages. In almost all situations, when a work injury happens, both parties know medical costs and lost wages will be handled through the workers' compensation system, regardless of who was at fault.

DURHAM, N.H. – Parents are much more likely to blame and doubt their children when their child has been sexually abused by another adolescent instead of an adult, according to new research from the Crimes against Children Research Center at the University of New Hampshire.
"Parents may have higher levels of blame toward their child when sexually abused by adolescents because parents have difficulty with the concept of adolescent sex offenders. Some parents may still expect the offender to be an older stranger rather than someone who their child knows, trusts, and is close ...

Boston, MA – Despite a national mandate to implement electronic health records and computer order entry systems (CPOE) by 2014, only approximately 30 percent of hospitals nationwide have done so and around 40 percent of hospitals in the state of Massachusetts have made this transition. New research from Brigham and Women's Hospital examined the impact of a vendor-developed CPOE in five community hospitals in Massachusetts and found that these CPOE systems are effective at reducing drug-related injury and harm. This research is published online in the Journal of General ...

DURHAM, N.H. – Americans' knowledge of facts about the polar regions of the globe has increased since 2006, but this increase in knowledge has not translated into more concern about changing polar environments, according to new research from the Carsey Institute at the University of New Hampshire.

When it comes to diets, cookies and cake are off the menu. Now, in a surprising discovery, researchers from Tel Aviv University have found that dessert, as part of a balanced 600-calorie breakfast that also includes proteins and carbohydrates, can help dieters to lose more weight — and keep it off in the long run.
They key is to indulge in the morning, when the body's metabolism is at its most active and we are better able to work off the extra calories throughout the day, say Prof. Daniela Jakubowicz, Dr. Julio Wainstein and Dr. Mona Boaz of Tel Aviv University's Sackler ...

The terrible truth about the danger of football head injuries keeps piling up. Many former pro players are burdened later in life with dementia and other forms of long-term cognitive loss. Some of these players are suing the NFL, seeking compensation for their injuries.
But the problem of brain damage suffered in sports competition isn't present only at the professional level. As knowledge of the problem increases, state legislatures have begun to respond with laws aimed at making competition safer in youth sports.
This is a development that Ohio brain injury lawyers ...
