Tobacco control policies stop people from smoking and save lives, study finds 2013-07-07

By Georgetown University Medical Center

Tobacco control measures put in place in 41 countries between 2007 and 2010 will prevent some 7.4 million premature deaths by 2050, according to a new study.

'First bionic eye' retinal chip for blind 2013-07-07

By University Hospitals Case Medical Center

A new bionic eye works by converting video images captured by a miniature camera, housed in the patient's glasses, into a series of small electrical pulses that are transmitted wirelessly to an array of electrodes on the surface of the retina. These pulse

Getting a good night's sleep is a nightmare for many Americans 2013-07-07

By Loyola University Health System

Summer means more hours of daylight and for many, it contributes to trouble falling asleep. More than 40 million Americans suffer from chronic sleep disorders, resulting in $18 billion in cost to employers due to sleep loss issues.

Dendritic cell therapy improves kidney transplant survival, team finds 2013-07-07

By University of Pittsburgh Schools of the Health Sciences

A single systemic dose of special immune cells prevented rejection for almost four months in a preclinical animal model of kidney transplantation, according to experts. Their findings could lay the foundation for eventual human trials of the technique.

Inside the minds of murderers: Impulsive murderers much more mentally impaired than those who kill strategically 2013-07-07

By Northwestern University

The minds of murderers who kill impulsively, often out of rage, and those who carefully carry out premeditated crimes differ markedly both psychologically and intellectually, according to a new study.

Better antibiotics: Atomic-scale structure of ribosome with molecule that controls its motion 2013-07-07

By DOE/Lawrence Berkeley National Laboratory

Scientists have created an atomic-scale structure of a bacterial ribosome attached to a molecule that controls its motion. The image is also a possible roadmap to better antibiotics. Somewhere in its twists and turns could be a weakness that a new antibio

Scientists discern signatures of old versus young stem cells 2013-07-07

By Stanford University Medical Center

A chemical code scrawled on histones -- the protein husks that coat DNA in every animal or plant cell -- determines which genes in that cell are turned on and which are turned off. Now, researchers have taken a new step in the deciphering of that histone

Helping SAD sufferers sleep soundly 2013-07-07

By University of Pittsburgh

Gene deletion affects early language and brain white matter 2013-07-07

By Baylor College of Medicine

A chromosomal deletion is associated with changes in the brain's white matter and delayed language acquisition in youngsters from Southeast Asia or with ancestral connections to the region, said an international consortium led by researchers at Baylor Col

Biochemists identify protease substrates important for bacterial growth and development 2013-07-07

By University of Massachusetts at Amherst

Scientists describe using a combination of biochemistry and mass spectrometry to "trap" scores of new candidate substrates of the protease ClpXP to reveal how protein degradation is critical to cell cycle progression and bacterial development. T

Polymer coatings a key step toward oral delivery of protein-based drugs 2013-07-07

By Brown University

In a new study, a "bioadhesive" coating significantly improved the intestinal absorption into the bloodstream of nanoparticles that someday could carry protein drugs such as insulin. Such a step is necessary for drugs taken by mouth, rather than

New maps depict impact of HIV in America 2013-07-07

By Emory Health Sciences

New interactive online maps that show the latest HIV prevalence data for 20 US cities by ZIP code or census tract. AIDSVu also includes new city snapshots displaying HIV prevalence alongside various social determinants of health -- such as poverty, lack o

Radiation from airport scanners: The dose we actually get is low 2013-07-07

By American Association of Physicists in Medicine (AAPM)

A new report has found that people absorb less radiation from airport X-ray backscatter scanner than they do while standing in line waiting for the scan itself.

Researchers reformulate the model of mitochondrial function 2013-07-07

By Centro Nacional de Investigaciones Cardiovasculares

New findings will mean rewriting the biochemistry textbooks. The study redefines the functioning of mitochondria and explains how cells generate energy from nutrients.

Bringing long-term intensive care within hospital walls shows promise for cost savings and improved patient care 2013-07-07

By Columbia University School of Nursing

A new study shows that hospitals with specialized units combining the compassionate care of hospice and the level of care offered in medical-surgical units may provide efficient, cost effective assistance to patients with advanced chronic illness or termi
