Miscounting bioenergy benefits may increase greenhouse gas release

October 22, 2009

EAST LANSING, Mich. -- A fixable error in the way carbon is counted in current U.S. climate legislation and in the Kyoto Protocol could undermine efforts to reduce greenhouse gas emissions by using biofuels, says a premier group of national environmental and land use scientists.

Checkered history of mother and daughter cells explains cell cycle differences

October 19, 2009

When mother and daughter cells are created each time a cell divides, they are not exactly alike. They have the same set of genes, but differ in the way they regulate them. New research now reveals that these regulatory differences between mother and daughter cells are directly linked to how they prepare for their next split.

A major step in making better stem cells from adult tissue

October 18, 2009

LA JOLLA, CA -- October 15, 2009 A team led by scientists from The Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells. The research makes great strides in addressing a major practical challenge in the development of stem-cell-based medicine.

New laryngoscope could make difficult intubations easier

October 15, 2009

AUGUSTA, Ga. -- A new tool developed by a Medical College of Georgia resident and faculty member may make it easier to place assisted breathing devices under difficult circumstances.

About 2 percent of patients that undergo the process, called intubation, experience complications -- regardless if it's performed in an emergency situation or prior to surgery.

What drives our genes? Salk researchers map the first complete human epigenome

October 14, 2009

LA JOLLA, CA -- Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn't tell biologists much about how its function is regulated.

First-of-kind study shows model can be used to rate courtroom psychiatric experts performance

October 13, 2009

Court cases across America often feature expert testimony that offers conflicting conclusions. When this happens in cases involving psychiatric expertise, does it mean that one side or the other is necessarily being less than honest?

SCID kids leading healthy, normal lives 25 years after 'Bubble Boy'

October 13, 2009

DURHAM, N.C. -- Mention the words "bubble boy" and many will recall David Vetter, the kid with big eyes and a thick thatch of dark hair who died 25 years ago after spending almost the entire 12 years of his life in a germ-free, plastic bubble. David was born with severe combined immune deficiency, or SCID, a condition that robbed him of an immune system.

Child safety seat education needs an extra boost

Motor vehicle crashes are a leading cause of death among children despite the widespread availability of effective child passenger restraint systems (CPRSs) such as child safety seats.

Liver cells grown from patients' skin cells

October 8, 2009

Scientists at The Medical College of Wisconsin in Milwaukee have successfully produced liver cells from patients' skin cells opening the possibility of treating a wide range of diseases that affect liver function. The study was led by Stephen A. Duncan, D.

Being overweight super-sizes both risk and consequences of sleep-disordered breathing

October 7, 2009

Overweight individuals are not just at greater risk of having sleep-disordered-breathing (SDB), they are also likely to suffer greater consequences, according to new research.

Ancient China's sand dunes reveal unexpected dryness during heavy monsoon rains

October 6, 2009

The windswept deserts of northern China might seem an odd destination for studying the heavy monsoon rains that routinely drench the more tropical regions of Southeast Asia.

Models begin to unravel how single DNA strands combine

October 6, 2009
