(Landmark study on lowering the risk of CABG in high-risk patients reported at the American Association for Thoracic Surgery meeting)
NYU Medical Center’s cardiac surgeons Eugene Grossi, MD, and Aubrey Galloway, MD, announced new study findings demonstrating significantly lowered mortality, stroke, and overall risk of complications using off-pump coronary artery by-pass grafting (OPCAB) in high-risk patients. The findings were presented today during the Adult Cardiac Surgery Scienti
In studies that could be vital to an expanding field of industrial biotechnology, scientists at the Center for Biosystems Research are learning to censor what E.coli bacteria are ’talking’ about.
Cell-to-cell cross talking by laboratory E. coli strains engineered to produce antibiotics, industrial polymers or other products in fermentation vessels can lead to stress in the culture and severely limit product output. But scientists with CBR and partners have begun to decipher and over
From the air and the ground, scientists this spring and summer will examine some of the world’s largest thunderstorm complexes, behemoths that can spread hurricane-force wind and torrential rain for hundreds of miles across the U.S. Midwest. The study, scheduled from May 20 to July 6, should provide the clearest picture to date of how such storms wreak havoc and how forecasters can better predict trails of storm damage. The Bow Echo and MCV Experiment (BAMEX) is organized by scientists
In photographs, it looks like a big red spaceship cruising the ocean depths. But it’s actually a new species of jelly that was discovered and described by scientists at the Monterey Bay Aquarium Research Institute. MBARI scientists published their research on this unusual animal in a recent online version of the journal Marine Biology.
With a bell diameter of up to a meter wide, the new jelly, named Tiburonia granrojo or “big red,” would seem tough to miss, except that it lives deep below t
Oil geologists now have a new villain to worry about – the digestive processes of the marine worm.
Clay minerals are the bane of an oil geologist’s life. They sit in pore spaces and block the necks of communication between them, so reducing both porosity and permeability – the two essential characteristics of an oil reservoir, which holds the precious black fluid, like a sponge.
Now, researchers based in Liverpool University have shown that these troublesome minerals are cru
Researchers from Infineon Technologies AG have developed a way to make large textile surfaces such as carpeting or tent cloth “intelligent”. This technology innovation may lead to new products for the monitoring of buildings, the structural control of buildings of all kinds and for use in the advertising industry.
Woven into fabrics, a self-organizing network of robust chips is able to monitor temperatures, pressures or vibrations as required. In addition to the sensor functionality,
Enhances Potential for Future Development of B-Cell Based Therapy for Lupus
Researchers at the University of California, San Diego—supported by the Alliance for Lupus Research and the National Institutes of Health—have for the first time described a method that Staphylococcus aureus (staph) infection uses to inactivate the body’s immune system. A protein produced by the staph bacteria causes previously healthy B cells—a specialized cell of the immune system—to commit suicide, a proce
Children who frequently change schools are more likely than those who don’t to have behavioral health problems, according to a new Cincinnati Children’s Hospital Medical Center study.
The study, to be presented Sunday, May 4, at the annual meeting of the Pediatric Academic Societies in Seattle, shows that school mobility is an independent predictor of behavioral problems – regardless of one’s race, income, maternal education level or any other factor measured in the study.

Interventional radiology procedures are effective in treating uterine fibroids in patients who have symptoms of the disease without causing infertility or premature menopause, a new study shows.
Uterine fibroids are nourished by blood, says Hyun S. “Kevin” Kim, MD, of Johns Hopkins Medical Institutions in Baltimore and the lead author of the study. “We found that if we block the uterine and ovarian arteries feeding the fibroid, the patients symptoms are relieved,” he says. The arteries are
Voice recognition dramatically decreases the turnaround time for radiology reports – referring physicians are often getting results the same day their patients have the radiologic examinations – but technical problems with these systems are reducing some radiologists to typing rather than dictating those reports, a new study shows.
“There are many benefits of voice recognition, but unfortunately we have been facing some technical problems that are impacting our productivity, ” s
Thermography provides the easy checking of points throughout an electric system where faults may arise, and with sufficient warning in order to correct the fault before things get worse.
Infrared thermography provides the visualisation of temperature differences arising at the surfaces of objects. The tool used is a portable and autonomous camera (similar to a home video camera) which is equipped with a detector which permits the measurement and visualisation of thermal images.

Scientists at Bristol University have found evidence for a new protein in the heart that could one day aid development of new drugs to regulate the heart.
The ability of the heart to function as a pump that drives blood around the body depends on the electrical behaviour of muscle cells from various regions of the heart. Different cardiac regions have distinct electrical events, specialised for their particular roles in the heart.
While studying the electrical activity of he
Researchers at the University of Pennsylvania have created the first mammalian gametes grown in vitro directly from embryonic stem cells. The work, in which mouse stem cells placed in Petri dishes — without any special growth or transcription factors — grew into oocytes and then into embryos, will be reported this week on the web site of the journal Science.
The results demonstrate that even outside the body embryonic stem cells remain totipotent, or capable of generating any of the body&
Solving a longstanding scientific puzzle, researchers at the University of Illinois at Chicago have not only discovered how the body’s first line of defense against dangerous microbes inadvertently helps HIV rapidly infect the human immune system.
They’ve filmed the process as well.
In a remarkable series of movies created with images from time-lapse microscopy, UIC microbiologists Thomas Hope and David McDonald have documented how HIV enters human T cells, where it multip
In the fall of 1952, Stanley Miller, now a chemistry professor emeritus at the University of California, San Diego (UCSD), began simulating primitive earthly conditions in an experiment that produced the basic building blocks of life. When he published the results in Science on May 15 the following year, he kick-started research on the origin of life and transformed modern thinking on a dormant area of science.

Results from Model-based functional genomics research provides new insight on the pathogenetic mechanism which causes diseases such as ALS
Ingenium Pharmaceuticals AG and a coalition of international research organizations announced today the publication in Science of research describing a fundamental discovery about the genetic and molecular basis for Motor Neuron Disease (MND), which includes Amyotrophic Lateral Sclerosis (ALS). The research explains a key pathogenetic mechanism of
