COLUMBUS, Ohio -- Ohio State University researchers have developed a new method for making extremely pure, very small metal-oxide nanoparticles.

They are using this simple, fast, and low-temperature process to make materials for gas sensors that detect toxic industrial chemicals (TICs) and biological warfare agents.

The researchers described their work in a recent issue of the journal Materials Chemistry and Physics.

(Boston) - Researchers from Boston University School of Medicine (BUSM) have shown that patients with uncontrolled hypertension respond to treatment intensification regardless of their degree of adherence to antihypertensive medications. This study, which has been published online in Hypertension could have an immediate impact on clinical care, as it challenges a widely held assumption.

(Boston) – Boston Medical Center (BMC) researchers have identified potential safety risks among methadone maintenance treatment (MMT) patients due to the quantity and accuracy of medical record documentation. Improved communication and coordination among substance use treatment and medical providers could mitigate and manage the potential adverse effects of methadone and interacting medications. The BMC study appears in the July issue of Journal of General Internal Medicine.

COLUMBUS, Ohio – A study comparing how two common dietary oil supplements affect body composition suggests that both oils, by themselves, can lower body fat in obese postmenopausal women with Type 2 diabetes.

Errant pixels and blurry regions in a photo, whether digital or scanned, are the bane of photographers everywhere. Moreover, in vision processing research degraded photos are common and require restoration to a high-quality undegraded state. Research published this month in the International Journal of Signal and Imaging Systems Engineering could provide new insights.

Current combination malaria therapies recommended by the World Health Organisation (WHO) provide adequate treatment for mild malaria, according to a Cochrane Systematic Review of the evidence. However, selected trials had high failure rates for some combinations and evidence for the effectiveness of anti-malarial therapies is lacking in some vulnerable groups.

Video from portable cameras is analyzed to calculate the distance of obstacles and predict the movements of people and cars. This information is then transformed and relayed to a blind person as a three-dimensional ‘picture’ of sound.

The concept is seemingly simple and two prototypes have been successfully tested. Laser and digital video cameras become the eyes for the blind man and see the objects and activity going on around him or her.

One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them.

A team of Rice University bioengineering students who invented a device to measure intrinsic hand muscle strength has won two prestigious honors for their patent-pending creation, PRIME. The device could revolutionize the diagnosis and treatment of hand injuries and neurological disorders, specifically carpal tunnel syndrome.

The OrthoIntrinsics team won first place and $10,000 at IShow, an innovation competition for graduate and undergraduate students sponsored by the American Society of Mechanical Engineers in Palm Desert, Calif., this June.

Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors. The approach, which makes novel use of polarized light to create "effective" magnetic fields, could bring the long-sought computers a step closer to reality.

A study of more than 64,000 pregnant women has found that miscarriage rates following amniocentesis and chorionic villus sampling (CVS) - two invasive procedures to detect chromosomal abnormalities and birth defects - were 1.4 per cent and 1.9 per cent, respectively.

The research, published in the July issue of Ultrasound in Obstetrics and Gynecology, also found that the number of procedures carried out by a department had a significant effect on miscarriage rates.

Salem, MA, July 6, 2009 – The Society for Vascular Nursing (SVN) has released the first in a series of guidelines being developed that will focus on the nursing care of patients with vascular disease. Working as a collective group of experts, members of SVN have developed guidelines based on the latest available evidence supporting patient care, 2009 Clinical Practice Guideline for Patients Undergoing Endovascular Repair of Abdominal Aortic Aneurysms (AAA), which appears in the June issue of the Journal of Vascular Nursing published by Elsevier.

Tiny flying machines can be used for everything from indoor surveillance to exploring collapsed buildings, but simply making smaller versions of planes and helicopters doesn't work very well. Instead, researchers at North Carolina State University are mimicking nature's small flyers – and developing robotic bats that offer increased maneuverability and performance.
