Yale team finds order amidst the chaos within the human genome
2012-09-06
Within the genome, sex does matter
Yale researchers studying the human genome say they can now tell how much "mom" and how much "dad" is genetically active in each of us.
These gender-specific markers may not determine which parent can take credit — or the blame — for the successes or shortcomings of their offspring; however, they could help explain differences in human populations.
"We can now track the relative genetic contribution of mom and dad," said Gerstein.
All human beings are born with two copies of the genome — one from the mother and one from the father. ...
Loss of tropical forests reduces rain
2012-09-06
Deforestation can have a significant effect on tropical rainfall, new research confirms. The findings have potentially devastating impacts for people living in and near the Amazon and Congo forests.
A team from the University of Leeds and the NERC Centre for Ecology & Hydrology found that for the majority of the Earth's tropical land surface, air passing over extensive forests produces at least twice as much rain as air passing over little vegetation. In some cases these forests increased rainfall thousands of kilometres away.
By combining observational data with predictions ...
Mapping a genetic world beyond genes
2012-09-06
Cambridge, MA. Wed. September 5, 2012 – Most of the DNA alterations that are tied to disease do not alter protein-coding genes, but rather the "switches" that control them. Characterizing these switches is one of many goals of the ENCODE project – a sweeping, international effort to create a compendium of all of the working parts of the human genome that have not been well studied or well understood.
The function of the vast majority of the human genome has remained largely unknown, but the Encyclopedia of DNA Elements (ENCODE) project, launched in 2003, set out to change ...

The Consensus in Sport (CIS) guidelines were developed following the first international conference on concussion in sport in 2001.
This was convened by the International Ice Hockey Federation, FIFA (Federation Internationale de Football Association), and the International Olympic Committee Medical Commission in recognition of the inevitability ...
Tests for silent neck artery narrowing to curb stroke risk: Waste of resources
2012-09-06
Tests to screen for "silent" neck artery narrowing in a bid to curb the risk of a stroke result in many unnecessary and costly surgical procedures, and ultimately save very few lives, concludes an editorial in the Journal of NeuroInterventional Surgery.
In 2-6% of European men aged 60 plus, the major arteries supplying the brain (carotid arteries) are narrowed by 50-99%. This condition, termed carotid stenosis or atherosclerosis, accounts for 10-15% of strokes (data not in paper).
Carotid atherosclerosis is commonest in those with mild peripheral arterial disease in ...
In massive genome analysis ENCODE data suggests 'gene' redefinition
2012-09-06
Cold Spring Harbor, N.Y. – Most people understand genes to be specific segments of DNA that determine traits or diseases that are inherited. Textbooks suggest that genes are copied ("transcribed") into RNA molecules, which are then used as templates for making protein – the highly diverse set of molecules that act as building blocks and engines of our cells. The truth, it now appears, is not so simple.
As part of a huge collaborative effort called ENCODE (Encyclopedia of DNA Elements), a research team led by Cold Spring Harbor Laboratory (CSHL) Professor Thomas Gingeras, ...
Millions of DNA switches that power human genome's operating system are discovered
2012-09-06
The locations of millions of DNA 'switches' that dictate how, when, and where in the body different genes turn on and off have been identified by a research team led by the University of Washington in Seattle. Genes make up only 2 percent of the human genome and were easy to spot, but the on/off switches controlling those genes were encrypted within the remaining 98 percent of the genome.
Without these switches, called regulatory DNA, genes are inert. Researchers around the world have been focused on identifying regulatory DNA to understand how the genome works. ...
Call for a new approach to fighting tuberculosis
2012-09-06
Boston, MA – Each year, nearly 2 million people die from tuberculosis – a treatable disease that has been brought under control in the United States, but continues to ravage other parts of the world. This health inequity should prompt a complete rethinking of the way tuberculosis is fought on a global level, argue Salmaan Keshavjee, MD, PhD, and Paul Farmer, MD, PhD, from Brigham and Women's Hospital (BWH). Their argument appears in an essay published September 6 in the New England Journal of Medicine.
"The global approach to fighting tuberculosis has been lacking," ...

Seeing the birth of the universe in an atom of hydrogen
2012-09-06
Windows to the past, stars can unveil the history of our universe, currently estimated to be 14 billion years old. The farther away the star, the older it is — and the oldest stars are the most difficult to detect. Current telescopes can only see galaxies about 700 million years old, and only when the galaxy is unusually large or as the result of a big event like a stellar explosion.
Now, an international team of scientists led by researchers at Tel Aviv University have developed a method for detecting galaxies of stars that formed when the universe was in its infancy, ...
Genome-wide scan maps mutations in deadly lung cancers; reveals embryonic gene link
2012-09-06
Scientists have completed a comprehensive map of genetic mutations linked to an aggressive and lethal type of lung cancer.
Among the errors found in small cell lung cancers, the team of scientists, including those at the Johns Hopkins Kimmel Cancer Center, found an alteration in a gene called SOX2 associated with early embryonic development.
"Small cell lung cancers are very aggressive. Most are found late, when the cancer has spread and typical survival is less than a year after diagnosis," says Charles Rudin, M.D., Ph.D., professor of oncology at the Johns Hopkins ...
Hospital-acquired UTIs rarely reported in data used to implement penalties
2012-09-06
ANN ARBOR, Mich. — Aiming to cut expenses and improve care, a 2008 Medicare policy stopped paying hospitals extra to treat some preventable, hospital-acquired conditions – including urinary tract infections (UTIs) in patients after bladder catheters are placed.
But a statewide analysis by the University of Michigan shows there was very little change in hospital payment due to removing pay for hospital-acquired catheter-associated UTIs. For all adult hospital stays in Michigan in 2009, eliminating payment for this infection decreased hospital pay for only 25 hospital ...
LEDs winning light race to save energy, the environment
2012-09-06
RICHLAND, Wash. – Today's light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in the next five years, according to a new report from the Department of Energy's Pacific Northwest National Laboratory and UK-based N14 Energy Limited.
"The light-emitting diode lamp is a rapidly evolving technology that, while already energy efficient, will become even more so in just a few short years," said Marc Ledbetter, who manages PNNL's solid-state ...
Exceptional upward mobility in the US is a myth, international studies show
2012-09-06
ANN ARBOR, Mich.—The rhetoric is relentless: America is a place of unparalleled opportunity, where hard work and determination can propel a child out of humble beginnings into the White House, or at least a mansion on a hill.
But the reality is very different, according to a University of Michigan researcher who is studying inequality across generations around the world.
"Especially in the United States, people underestimate the extent to which your destiny is linked to your background. Research shows that it's really a myth that the U.S. is a land of exceptional social ...
